Important Factors That Affect the Textile Finishing


Methods of wet application of finishes on fabrics are mostly either by exhaustion techniques or by padding concentrated solution and depend on the substrate and the feasibility of adopting either of the processes. Applications by foam applicator by spray techniques are common in the case of made up garments.
Whereas padding method of application is feasible for all softeners, exhaust method of application is possible only where the softener has good substantivity. However high substantivity could cause tailing in a pad box application and requires to be controlled - discussed under padding method of application.

Softeners are the most employed finishing agents either by themselves or along with other body builders/modifiers. Majority of the softeners are cationic. Cationic reactive softeners based on amino silicones play very important role to provide the lubricity to facilitate better sewability and also permanency to the finish.

The fabric substrate pH, the stability of the bath pH, the ionic character of the residual chemicals that may be left behind from the previous treatment, incomplete or variation in drying, yellowness, high TDS/ hardness can all influence different finishes differently.

Turkish Carpet Industry Invests In French Machinery

The production of traditional and modern style carpets in the fast growing Turkish city of Gaziantep is about 300 millions square meters in 2008. The process includes state of the art spinning and weaving machines, much of them from France.

Gaziantep, the Turkish cluster for carpet manufacturing - Turkey has a long tradition of carpet craftsmanship. In the South-East of the country, a little more than one hour fly from Istanbul, close to the Syrian border, a 1 million people city, Gaziantep, has grown to become the capital of the machine made carpet industry. Modern housing and manufacturing plants are built at such a speed that the city looks really different every few months.

The textile industry and particularly the carpet manufacturing are responsible for a good part of this exceptional growth explains I.Yalçin Konukoglu, the President of the Gaziantep carpet makers Association.

He explains “in Gaziantep and its close vicinity, there are 189 carpet mills which employ directly or indirectly more than 30 000 employees. These mills represent more than 80% of the Turkish carpet industry and 70% of them are vertically integrated, they spin their own yarns and weave the carpets. Not long ago they were running about 3 000 locally made weaving machines, less than 200 are still in use but 650 modern weaving machines have been erected giving the area an annual capacity of 300 millions square meters.”

President Konukoglu analyses the success of these companies, small or big: “their entrepreneurship spirit with a clear and consistent strategy to go after the mass market worldwide, offer good quality, maintain low production costs and sell at reasonable profits; follow the fashion trends on the different markets worldwide”. One main trend has been the shaggy carpets (long hair), it is here in Gaziantep that it has been developed.

Textile Machinery Trade Fairs: Through The Eyes Of Textile Industry

Trade fairs and events are mainstay for the textile machinery companies market promotion. Various trade fairs and events are organized every year by organizers like ACIMIT, TMMA, CSMA, JASMA, CITME etc. Some fairs like ITMA, JIAM exclusively focuses on textile machinery sector while some other includes machinery as an integral part of textile industry. Such fairs have become potential hub of meeting for buyers and sellers. Unique Selling Preposition of such fairs is that manufacturers can display their machinery to the buyers directly and buyer can examine and negotiate on the spot for different parameters. Buyers can also compare different machines at the same place for their prices, applications and technologies used.



Textile machinery manufacturers and visitors attend such fairs with different expectations and perceptions. Decision to visit fairs/event depends on many factors like geographical location of the fair, visitors profile, past experience with the fair, reputation of the fair within industry etc. Fibre2fashion got the opportunity to know views of eminent personalities in machinery manufacturing industry. Mr. S. R. Gandhi (Dalal Engineering) says We prefer to participate in only those fairs which are only for Textile Machinery.

Amongst Machinery manufacturers fraternity, for companies like Dalal Engineering, ITMA is the most preferable trade fair. For ITMA, Mr. Rainer Thum (Head Marketing - Spindelfabrik Suessen GmbH) quotes Infrastructure in Munich was better than anything they had seen before, including Singapore! We had very good customer attendance, much more than we had anticipated. A major problem for many of our customers was the difficulty in getting visas. Overall it was a very good show.

Our company participates in about 10-15 fairs every year, mainly in Vietnam, Indonesia, India, Pakistan, Bangladesh, Thailand etc. Usually we choose only one fair in one country each year according to the reputation, scale and our experience of last fair, expresses Mr. Wang Xiao hu (Vice President) China Texmatech Co., Ltd.

Scope Of Collaborations And Joint Ventures In Indian Textile Machinery Industry

Technology is the key enabler for rapid growth of the textile engineering industry. Efforts should therefore be directed towards technical upgradation of the textile engineering industry, technology transfer, re-engineering, promotion of joint ventures, BPO and R&D efforts. Technology and brand play the most vital role in the decision of a customer to buy a machine. The other parameter, viz., productivity together with consistency of quality would be concomitant with technology. Factors like energy conservation, eco-friendliness, reduction in labour cost, facility of operation and services would influence demand.

Preamble

The willingness of foreign manufacturers to transfer technology, continuity of transfer, and cost of transfer are aspects to be considered while procuring new technology. In the regimented system prior to 1992, the Indian Textile Engineering Industry was abjectly dependent on borrowed technology. Consequently collaborations and joint ventures in India were largely influenced by the initiatives of the foreign companies. Very often the technology offered was one or two generations behind the latest technology available with the foreign collaborators. So long as the Indian textile industry was enjoying a protected domestic marked it could carry on with such second generation technology. With the opening up of the economy the situation has undergone a rapid change.

Technology transfer affected

The transfer of technology to the TEl after the dismantling of the control regime has been impacted adversely by the following factors:

In the first place, foreign collaborators have sought management control before technology transfer could be considered. Secondly, many Indian buyers found it difficult to infuse considerable fresh capital to absorb latest innovations and designs. Thirdly, because of the strident and sudden scaling down of customs tariff the foreign suppliers found it more lucrative to export machinery from their parent plant than to allow local producers to meet the domestic demand. Lastly, the volatile demand situation for textile machinery and accessories has come in the way of procuring new technology.

The foreign owners of new technology have therefore to be induced with fresh incentives. The primary bait for technology sellers would be royalty payment and large dissemination of technology on a continuous basis. Government has to be a prime mover of this initiative by offering tax breaks to the technology buyer to help royalty remittances. Tax relieves may also be offered on raw materials and other inputs which go into the manufacture of new technology machines by the domestic manufacturers.

How to obtain Technology

A combination of routes has to be vigorously pursued to obtain the latest technology for the rapid progress of the Indian Textile Engineering Industry. These include:

a) Joint Ventures with machinery manufacturers who may be interested in transfer of technology. In the quota free regime, the manufacturers proximity to user market would be advantageous and hence the machinery producers from abroad may be interested to expand their presence in India.
Since a large number of knitting machines of latest technology are being imported from Taiwan it would be advantageous to examine the feasibility of procuring such technology for the growing knitting industry. Access to new technology could also be explored with countries like the U.S.A., Italy, Japan, Korea and Taiwan.

b) Proposals for the establishment of latest looms have to be explored. With the altered perspective of countries like Italy, Germany, Switzerland, USA and Japan towards Indian economy, it would be worthwhile to seek collaborations with the textile machinery makers of those countries to hollow out their operations to India, particularly in the weaving and processing sectors. Countries like Korea, Taiwan and Japan have developed electronics in a big way and efforts to procure the technology should be promoted.

c) Technology transfer may be encouraged through reengineering. Countries like Japan, China, Korea and Taiwan have benefited greatly by resorting to retrofit. India is currently importing a large quantity of used machinery, some of them with improved technology. An institutional arrangement could be set up to re-engineer and disseminate imported technology through a nodal agency.

New Hot Knives Can Cut High-Tech Vectran Fiber

High-tech organic fibers such as aramids are used in a variety of nonwoven and fabric applications where strength, toughness, abrasion resistance and resistance to cutting are important parameters. In safety applications such as personal protective equipment, gloves, chain saw chaps, protective apparel and others, the resistance of the material to blade cuts is essential to success of the product.

Now the downside – during cut-and-sew operations to assemble the final net shape, resistance to cutting by knife blades can be a problem and can increase production time and costs.

One of the more recent entries into the market for protective materials is Vectran, a liquid crystal polymer fiber made by Kuraray. Vectran fiber’s unique properties provide a number of benefits over aramids including superior strength, abrasion resistance and cut resistance. Vectran fiber can provide product designers and engineers with an alternative to aramids for applications from composites used in aerospace to flexible coated fabrics and protective apparel.

While cutting thick Vectran fabric samples for laboratory testing, Kuraray noted a rapid degradation of cutting speeds as blades dulled due to the hard nature of the LCP polymer used to produce the fibers. Because of the difficulty experienced in cutting Vectran, Kuraray turned to the German-based equipment manufacturer, HSGM (Heissschneide- Geräte und -Maschinen) to make recommendations for possible heat cutting of Vectran. Material samples were sent to HSGM’s testing lab in Walluf, Germany.

In heat cutting, the blade of the cutting tool is heated to a temperature above the zero-strength temperature of the fiber. After several cutting trials, HSGM was able to cut Vectran fabrics at a good speed and produce a welded edge, when using the proper heat settings and recommended blades.

“We found the Vectran very difficult to cut by conventional means,” said Stephan Herrmann, general manager, HSGM, Germany. “However, because of the fiber’s unique thermal properties we were able to soon find the right combination of heater and blade design. Comparing hot cutting of Vectran to hot cutting aramids, Vectran could be hot cut easier and a little bit faster.”
