Wet Dry And Functional Fabrics Key Technologies Fabrics

by the Wuhan Textile University, Wuhan Yi Ling Knitting Co., Ltd. and Ji Hua 3509 Textile Co., Ltd., the project "< a href=" http://www.91se91.com/news/index_c.asp > dry wet dry functional fabric < /a > production key technology "has recently won the 2013" textile light "science and technology two prize. At present, the moisture conductive and dry functional fabrics have been widely used in sports and casual clothing, which can effectively improve the clothing environment and thermal comfort of human body. The microclimate between human skin and inner garment fabrics is the key factor that affects the physiological comfort of clothing. Under the condition of changing the level of human metabolism in the atmospheric environment, if the microclimate can be stabilized near the comfortable standard microclimate, it can solve the problems of natural fiber fabrics such as water holding capacity and lack of dry and easy. The key technology of "wet dry and functional fabric production" has been achieved by the use of dry modified polyester low elastic yarn and ordinary polyester low elastic yarn for weaving wet graded knitted fabric and dyeing and hydrophilic finishing. The clothes made of it can sweat quickly into the outer layer of the fabric when people sweat a lot, so that the inner layer is always dry and keeps the good weather in the clothing. It is an ideal sport fabric.

 sports meeting is accompanied by sweating. It is very important for sweating to discharge in time to the psychological feelings and health of the pack. For young people, athletes and all kinds of sports enthusiasts at the growth stage, many engaged in manual workers have a larger amount of exercise, faster metabolism and more sweat. According to statistics, there are about more than 300 million primary and middle school students and sports enthusiasts in China. The annual demand for functional comfort sports fabrics is about 230 thousand tons. If coupled with the consumption demand of the general population for such clothing, it is expected to reach 350 thousand tons, so the total annual demand will reach 600 thousand tons. Therefore, manufacturers are committed to developing dry and wet comfort fabrics to meet the needs of the market. Dry and wet fabrics are also a hot topic in the current research. Wu Jihong, vice president of textile School of Wuhan Textile University, said the project leader. 
 at present, on the research and development of fabrics made of pure natural fibers with unidirectional sweating function, good results have been achieved through yarn modification and fabric structure design, but the durability and durability of products are still insufficient. At the same time, knitted fabrics made of pure natural fibers are also facing the problems of lack of water retention and dryness. Therefore, they are not suitable for sports clothing. 
 Sports fabrics are mostly knitted fabrics with polyester as the main body. Many manufacturers focus on moisture absorption and quick drying of raw materials, so there are many fiber materials with moisture absorption and quick drying function, such as Coolmax, Coolplus, Cooldry, coolking, Cooldry, Topcool, etc. These materials are applied to knitted fabrics, which play a good role in rapid moisture absorption and moisture spanmission, but they can not meet the requirements of people's dryness. In the existing research, the way of fabric printing is used, such as the mini window technology of the Cotton Corp of the United States, to achieve a certain one-way moisture spanfer function. However, the dry and dry function of this method is limited, which can not achieve the real sense of dryness, and the durability can not meet the requirements of use. Polypropylene is also used as a material for such fabrics, which can be dry and dry. However, the UV resistance of polypropylene is very poor, and its anti-aging ability is weak. It is not suitable for sports fabrics.

 establishing a scientific evaluation system 
 in order to fundamentally solve the dryness of fabrics, the research group conducted a lot of research before the development and thought that polyester is a good choice for sports fabrics. In order to obtain the function of wet semiconductor, the dry graded modified polyester and low elastic yarn is woven into wet gradient knitted fabric with the general < a href= "http://www.91se91.com/news/index_c.asp" > polyester < /a > low elastic yarn, and then realized by dyeing and hydrophilic finishing. 
 according to Wu Jihong, due to the wet dry and functional fabric is a new functional fabric. The comprehensive testing of the fabric requires a reasonable testing method. In order to reflect the comprehensive performance of the fabric, besides testing the instrument MMT, the project team has also developed a fabric moisture meter to detect the fabric, which provides a more scientific evaluation for the performance testing of the fabric. It is reported that the tester has been authorized by the invention patent and has been produced on a large scale. After several years of promotion, the product has been accepted by the international sports brand and some domestic sports brands, and has been affirmed by consumers. 
 the project has researched and developed the intelligent moisture conductive and dry type sports fabric with polyester as the main material. The fabric developed has good wet semiconductor intelligent characteristics, and the sweat can be quickly exported to the outer layer of the fabric when the clothes made by the manufacturer are sweaty. The inner layer is always dry and keeps the good weather in the clothing. It is an ideal sport fabric. The project has formed a series of technological achievements with independent intellectual property rights, ranking at the international advanced level. 
 Baotuan scientific research 
 all the parties in the industry, University and Research Institute are showing great powers. 
 the research of this project is of great significance for promoting the spanformation and upgrading of China's textile industry and promoting the development of related industries, and also promoting the development of the national sports industry. 
 in fact, when the research started, the parties of the industry, University and Research Institute have made a clear division of labor. Because the key technology of this fabric production is the integration of material modification, fabric structure design and finishing technology, the single manufacturer is more difficult to develop this product. Therefore, the project is jointly completed by Wuhan Textile University, Wuhan Ying Knitting Co., Ltd. and Jihua 3509 Textile Co., Ltd., the project is designed by Wuhan Textile University, the 3509 Textile Co., Ltd. is responsible for the implementation of yarn modification, Wuhan Yiling Knitting Co., Ltd. is responsible for the implementation of the reorganization, the manufacturer has invested 3 million yuan in research and development, and three parties have implemented intellectual property sharing, and the joint mode of production, study and research is shared by technological achievements. Over the past two years, the total output value of the product has reached 110 million 800 thousand yuan, and profits and taxes are 25 million 900 thousand yuan. "At present, the three parties are ready to apply for their own brands on the production technology products, carry out market-oriented operation, and enlarge and strengthen the product." Wu Jihong said. 
 it is reported that the wet and dry functional fabric achieved by the project has the greatest advantages compared with the conventional moisture absorption and quick drying fabric: the product is lightweight, dry and fast drying with remarkable effect and good durability. The products have been processed into sports and sportswear garments by Adidas, Puma, Kappa, Lining, XTEP and MIZUNO at home and abroad.
