Ensuring Quality And Quantity In Weaving

Anyone who wants to produce top quality woven goods in high volume, and wants to stay competitive in the bidding for orders, must first and foremost have their planning and organization under control. An additional criterion is thorough familiarity with the entire production process, from fibre to fabric, to ensure that fabric production is profitable.


A precondition of optimum production in the weaveroom is meticulous planning. It is at the planning stage that process parameters, sequences of operations and working conditions are defined, all of which are relevant to profitability. The basis for these is optimal installation of the weaving machines, with appropriate transport routes and equipment. Additionally, capacities must be planned and the necessary infrastructure and resources created, including buffer store, air conditioning, lighting, personnel, quality control etc. This article spotlights key points that it is essential to take into account in the planning and organization of a weaving facility.


Yarn Quality


High yarn quality ought to be a matter of course. But its importance has to be pointed out repeatedly, because 80% of weaving machine stoppages originates in upstream process stages. In non-verticalized mills, all yarns supplied should be inspected on receipt. Not only the uniformity of the yarn is important; damaged packages are a sign of poor transport quality, and on the weaving machine they not only impair productivity but also cause waste. If there are no yarn reserves in the weft packages the result will be a weft stoppage. Thread breaks in weaving are the largest cost factor in the entire production process, because they always involve a machine stoppage.


Proportion of the different departments in the total thread break costs
In the textile manufacturing process, thread break costs in weaving are far higher than in all other stages of production. Every stoppage prevented directly improves the company's profits.

New Digital Textile Printing Studio Opens

After nearly five years in a space less than 75 feet square, University of Nebraska-Lincoln ‘s
TCD digital textile printer and related equipment have been relocated to new quarters in Room 227, the former storage center for the historic textile collection.

As the historic textile and historic costume collections are moved to what was once the International Quilt Study Center storage facility, space in the department is being released for other uses, and we'll continue to report on these as the various projects are finished up.

The new space for the printer operation, nearly 275 square feet, has an integral humidifying system that maintains an optimum temperature of 71 degrees and a humidity level of 55%, ideal for best printer performance.

In addition, the Jacquard steamer is now in closer proximity to the printer, and its move means that sessions with the digital printer will no longer mean distractions or interruptions in the classes that were often ongoing where the printer was previously located. The addition of a window to the studio door also means that visitors to the department will be able to more easily observe the printer in action.

Spanish Textile Machinery Industry

Quick Flight to Industry Overview


The European Union has emerged as a one large scale exporter of textile machinery in the international scenario. Some other countable and creditable manufacturers and exporters of textile machinery include Italy, Germany and Spain. In all of them Spain has sprung out as an important manufacturer of textile machinery and has secured its place by the 11th rank world wide. Diversification and innovation played a major role in the retainable position of Spain. About 69 machinery companies gain financial credit worth 245 million Euros in the Spain. This sector evolves 2600 jobs.

Spanish textile machinery industry has flourished with the structure of small and medium sized companies with the strength of less than 50 employees. These companies are still facing very tough competition with the world leaders to achieve the international standards of price, design, quality and service. Weaving machine spare parts, knitting, sewing, accessories and spinning are the different categories included under the textile machinery sector of Spain. 90% of this sector of textile machinery of Spain is occupied by small and medium scale companies which has strength of less than 50 employees.
Now-a-days maximum no. of companies are outsourcing the manufacturers of parts for the workshops designed for special purposes. Some companies have specialization in product research and development and innovations and some have in machine assembly phases.
Technical textile has grown more in the last decade. Major change is seen in “traditional textiles” so changes play major roles in products also like modifying or diversifying products of machinery. The related sectors for this are agriculture, hygiene and medicine, chemicals, packing and packaging and automotive industry.

Research and Development is a Keyword for Growth
Spain is giving special attention on the Research and Development of the textile machinery sector
and has started new centers to give way to new innovation process. Spain’s machinery companies took guidance from these centers to provide most technologically competitive machineries and due to this Spain’s textile machinery are always in demand. The export of machinery in Spain is of 70% of its total production.
The most aimed destination for the Spanish exporters is European Union and it is two third of the total exports of the country. The exports in the countries like Latin America, North America and Middle East is also noteworthy. New destinations like USA, Mexico, France, Turkey and India have new developing markets which are the reasons for the rise in the demand of progress. These destinations are five most targeted destinations for exports of textile machinery in the year 2006.

Geographical Distribution and Production
The good research & Development and innovations lead Spain in the global market in the technical textiles. The investment by this sector is 2.30 billion Euros in research and development projects and 4.60 billion Euros in new facilities and capital goods. The production in different regions of Spain is 3% in Valencia, 64% in Catalonia and 32% in Madrid of total sales. There are only two companies in Madrid though its contribution is of 32%.

Progressive Structural Changes of the Sector
Dyeing and finishing is a very much important sub sector of Spain. This dyeing and finishing sector consists of 32 companies and is the leading sector of country.

Yarn Quality Improved by ACP Quality Package

Preliminary Remarks

Today, the well-known 3-roller double-apron drafting systems of ring spinning frames permit to draft rovings up to a total draft of 80 and more under optimum conditions. The task of the break-draft zone is to introduce the sliding process of the fibres of the twisted roving. In the subsequent main draft zone, the fibre strand is guided between the top and the bottom aprons and drafted to the desired final count of the yarn.

This mode of operation is already very old and has hardly been modified in the last decades.

With the ACP Quality Package by SUESSEN it is now possible, however, to improve the drafting process in the main draft zone and consequently the values of the most important yarn parameters.

The Drafting Process on the Ring Spinning Machine
2.1 The Break-Draft
The purpose of the break-draft zone is to prepare the main draft. The fibres in the roving are stretched and extended up to a degree which allows them to shift in the main zone immediately after leaving the cradle clamping line.

The basic correlation for each individual staple length between the setting of the break-draft zone and of the break-draft of a ring frame drafting system is shown in Fig. 2.

A long break-draft zone with the smallest possible break-draft must definitely be preferred. It reduces very clearly the wear of top roller cots and aprons and the load on the draft gearing, especially in the case of long machines.

In addition, the total system is less prone to climatic modifications, variations in fibre length and fluctuation in the drafting resistance of the roving.

2.2 The Main Draft
As a basic principle, each of the two pairs of rollers in a drafting zone produces a zone of fibre friction by pressure1. The fibre condensation caused by this pressure does not only have a vertical effect, but spreads from both sides into the fibre strand (Fig. 3).

Both fields of friction are finally responsible for fibre guidance and the extent of regularity produced by the drafting process. The two fields of friction should not overlap, nor should their spheres of activity be too far apart.

It is beneficial to the draft and degree of regularity achievable, if within a drafting zone the field of friction of the back roller pair reaches as far as possible into the drafting zone to guide the fibres as long as possible. The front field of friction should be short and strong so that only the clamped fibres are drawn out of the fibre strand. This ideal is however restricted by relatively close limits in design as a result of the geometrical conditions.

'Exempt Textile Sector From Ban On Used Machinery' – Mr Ismy, API

Recently the Indonesian government had announced to ban import of second hand machinery in the country. “This move on the part of the government is to help the domestic machinery industry as well as reduce energy consumption”, Mr Ansari Bukhari, Director General, Ministry of Trade and Industry, had said will announcing the same.

Since this decision may affect the textile industry which imports a sizeable amount of textile machinery, fibre2fashion.com spoke to Mr. Ernovian G. Ismy, Secretary General of the Indonesian Textile Association to get his views on the decision of the Ministry of Industry.

Mr Ismy said, “In our opinion the policy should be re-investigated since the local textile machinery industry is still unable to fulfill demand of machinery from textile industry and due to the ongoing crisis, some of the textile industry players are facing difficulties in purchasing the more expensive new machines.”

Contradicting the decision of the ministry, Mr Ismy added by saying that, “Not all used machines are in-efficient. Actually a few of the used machines are able to work for good periods of time and the biggest stumbling factor is that the textile industry in Indonesia lacks trust and support of the banking and financial agencies to fund purchase of new machineries.”

Indian Textiles - A Rare Combination Of Tradition & Modernity

Abstract

India claims 1st position in terms of the installed weaving capacity in the world, but it does not have much importance in terms of quality weaving as the share of shuttleless looms to the total shuttle looms in India is just 1.62%, which is very meager in comparison to the other countries. So the sector requires modernization by way of replacing the old/ordinary looms with modern looms. This is the need of the hour in order to sustain / expand market share and in meeting the requirement of apparel industry for quality fabrics.


It is conspicuous to every person engaged in the textile business that the textile industry occupies a unique place in the economy of the country by virtue of its contribution to the industry output, employment generation and foreign exchange earning. It commands respect as the largest employer, next to agriculture, providing employment to about 35.00 million people, directly. It accounts for 14% of industrial production and 17% of export.


The textiles of India bear the imprint of the fine craftsmanship of the Indian weaver. The skill of weaving with deft fingers, drawing patterns and creating designs, is an art, which has been handed down through generations from father to son, from time immemorial. These finest gossamer fabrics woven from yarns of superior finish are now being manufactured more and more on powerlooms. The emergence of powerloom has transformed an art into a modern industry, employing more than 7 million workers. The combination of traditional art and contemporary modern designs, have given an unique character to the Indian powerloom textiles. The modernization process undertaken by the powerloom industry has widened the scope of products such as grey, printed and dyed fabrics and cotton made-ups into a variety of sophisticated finished lines of a wide range of widths and sizes. Besides, the industry is now in a position to offer fabrics not only of cottons but also of rich blends of cotton, synthetics and other fibers. The process of economic liberalization has enabled the industry to become globally competitive, not only in terms of price, but also of quality. It is therefore not surprising that the total exports from the sector has grown from Rs.1917.66 crore in 1996 to Rs.8296.15 crore in the year 2005-06.


The top ten major importers of powerloom fabrics and made-ups of 100% cotton are USA, UK, Germany, Italy, Bangladesh, France, Greece, UAE, Sri Lanka, and Spain.

Roll of Technology in Fabric Design & Fashion Industry

Introduction

Technology has propelled the growth of human society in innumerable ways. From the basic needs of food, clothing and shelter to advanced robotics and health care, technology has rapidly assumed the status of an arguably indispensable and highly effective tool in the modern era. Clothing has always been both a necessity with regard to human civilization and a means of showcasing ones culture and interests. Social status, religious leanings, cultural diversity and professional status can all be amply reflected by ones clothes. A wide array of different styles of clothing is now possible, aided by powerful technological tools that supplement and shape the creative ideas of fabric designers.

Evolution of Fabric Design

In accordance with Darwinian principles, man is a remarkable example of adaptability. And a look at the way clothes have evolved only goes to illustrate this. In addition, the progress of mans concept of fashion has also transformed over the ages. Starting from merely covering ones body with natural fur to protect it from the vagaries of the natural elements in ancient periods of human existence to designing special suits and fabrics woven out of exotic materials to meet adverse environment requirements like space and desert surroundings, man has always shown ingenious capability to engineer requisite changes in the fabrics. The concept of fashion too has seen a marked shift with the variety of choices available in the present times. Of course, technology is a major driving force behind fashion trends.

The Role of Technology in Fabric Design and Fashion

One of the most significant outcomes of the famed Industrial Revolution was the mechanization of textile manufacture. The power loom and the mechanized cotton mill resulted in a huge increase in the quantum of production by shortening the time required for production manifold. In the more recent times, there has been a proliferation of novel materials designed, and this has enhanced both the quality and adaptability of fabrics. The so-called smart materials enable the production of clever fabrics, with high-end technology like atomic force microscopy and polymeric nanofibres going into the design, manufacturing and testing of these fabrics. Ranging from special applications like the design of suits for space travel, swimsuits and suits for military purposes to the usage of more durable and adaptable garments for daily use, these methods have proved to be extremely effective. Several research centres have sprung up to investigate these exciting possibilities. The role of computers is unarguably prominent in fashion technology. The visualization of the final design right at the conceptualization stage, down to the finest detail, making suitable modifications if so desired, automating several stages in the manufacturing process and, finally, executing quality control procedures - all of them involve computing at various levels of complexity. Be it creating an eye-catching design using CAD or running the computerized knitting and weaving machinery, automation is fast becoming the buzzword. Fashion courses nowadays invariably include a major technological thrust in the curriculum to enable prospective designers to be abreast with the latest trends.

Exciting Possibilities and Trends

How about having a single garment that one can use both in the summer and winter one that would change texture, colour and even shape in response to external environments? All these are gradually transcending from being mere fantasies to reality. Digital clothing that incorporates sensors in the very clothing that one wears and other fascinating possibilities lie in store - courtesy the largely interdisciplinary explorations into the field of fabric and fashion technology. At a more mundane level, one could most definitely be pleased by the thoughts of having clothes made to precise specifications at a much faster rate and with several times more durability. Technology is scaling tremendous heights and with it, so are all its applications. Textile and fashion design have in store lots of promises and continue to be a standing example of the prowess of technology. As Mark Twain puts it, the finest clothing ever made is a person's skin, but of course, society demands something more. So the quest for better clothing, better fabric and trendier garments continues unabated aided by technological advancements.

Hair Severity: A New Yarn Hairiness Parameter

The conventional measurements of yarn hairiness are not its true representation. Based on extensive studies, Premier has introduced a new parameter - Hair Severity (HS). HS represents the disturbing hairs. The Hair Severity can be tested at 400 m/min in the Premier iQ Qualicenter- the worlds most intelligent evenness tester and process control equipment. The HS Statistics 2007 provides a useful tool for the mills to benchmark the HS levels achieved over different count and material.



Introduction


Hairiness denotes the extent to which fibres protrude from the yarn body. Hairiness is an important surface property which has a direct impact on the performance of the yarn in the subsequent processes. It also has a bearing on the feel and appearance of the fabric. Certain minimum amount of hairiness is desirable for converting the yarn into fabric. However, when the length of the protruding hair crosses a critical limit, it poses severe constraints during fabric formation in Weaving and Knitting. The fabric quality also gets degraded due to Pilling and Fuzzy appearance created by the longer hairs.


Hairiness is a highly variable parameter which is influenced by various factors like Raw material quality, Process parameters in Spinning preparatory, Ring frame and also at Winding. Controlling longer length hairs is of primary importance for a yarn to perform better in subsequent processes. Increased production rates and Compact Spinning technology necessitates precise measurement of yarn hairiness deviation.

Drafting Aprons For Ring Spinning Machines

Aprons in the drafting system are, with the top roller cots and the ring travelers, those components having a strong influence on the quality of the yarn and the efficiency of the ring spinning machines.


Increases in output of the ring spinning machines, updated design of components of top weighting arms and nose bars have increased the demands put on aprons considerably. If one considers that over the last 15years the speeds of spindles have increased by about 40%, yet the lifespan of aprons whose working life is defined by the frequency of flexing, has remained practically the same, the improvements in polymer materials are obvious.


Construction Of Aprons


Synthetic rubber, mainly NBR based, is the most widely used material for the manufacture of top and bottom aprons. There are also leather, synthetic leather, PU and PU-coated materials. Synthetic rubber has become a leading material for this purpose because of its long life, a wide range of uses and because of its resistance to fibre finishing additives and abrasion.


A typical rubber compound for the outer or inner layer of an apron contains the base polymer as well as between 10 and 15 different additives, which also affect the various physical and mechanical properties of the various aprons.


Basically, aprons made of synthetic rubber are made in endless tubular form whereas leather or synthetic leather aprons are made open in strips and subsequently glued together to form an apron. The advantage of the tubular construction is the lack of a seam. The apron is uniform along its entire circumference.

CSITC To Start Third Round Trials In January 2009


The ICAC Task Force on Commercial Standardization of Instrument Testing of Cotton (CSITC) announces the start of the third Round Trials in January of 2009. Participation in a CSITC Round Trial is not limited to test centers using Uster HVI equipment. CSITC evaluations are based on test results and are not dependent on the manufacturer, model or kind of testing instruments used.

The purpose of these trials is to encourage standardization in cotton instrument testing to promote efficiency in cotton production and marketing, and to help participating cotton test centers to ensure that their results be on the same level as other test centers around the world. Test centers enrolled in the trials will receive detailed information about their results to enable them to improve performance. Round trial results for each test center will not be reported to the public, but overall results for the round trials as a whole will be published.

The round trials are conducted four times a year. The U.S. Department of Agriculture will ship a set of cotton samples before each trial to participating test centers with instructions to test the cotton six times each day for five days for length, uniformity index, micronaire, strength, reflectance and yellowness, for a total of 150 tests, and will collect the results. These results will be forwarded to the Fiber Institute of Bremen, Germany, who will analyze them and send evaluations to individual test centers.
