Shandong Daiyin spin The project of "development and industrialization of new summer moisture absorption and quick drying denim products" jointly completed by the Group Co., Ltd. and Wuhan Textile University recently won the second prize of 2013 "Textile Light" Science and Technology Award. "Development and industrialization of new summer moisture absorption and quick drying denim products" In view of the difficulties of traditional cotton lightweight denim products such as difficult weaving, poor wrinkle resistance and poor wearing performance, the research adopted the double filament short fiber composite spinning technology, expanded the application range of raw materials for denim yarn, and developed the hydrophilic finishing technology of denim fabric, The moisture absorption of cotton fiber and the moisture conductivity of filament are combined to realize jeans clothing Function of fabric moisture absorption and quick drying. The project product meets the national standard of functional fabric for moisture absorption and quick drying. The denim fabric made has the characteristics of light, thin, straight, good drapability, and bright luster, which plays an important role in demonstrating and promoting the optimization and upgrading of denim product structure.

Denim fabric can also be light, thin and fast dry

Traditional denim fabrics are mainly thick cotton Denim fabric Mainly, it did not compete with other traditional varieties (such as corduroy, khaki, etc.) in the market, and it is urgent to apply new technologies and new materials to enhance the market competitiveness of jeans. At present, elastic jeans and cool jeans have been studied in China, but the production technology of jeans has not changed significantly.

With the development of clothing fabrics towards the direction of light and thin, the spinning technology of many existing raw materials, such as hemp fiber, wool fiber, cellulose fiber and superfine yarn, is currently the focus of international research and development. It is also an urgent need for cowboy production enterprises to use high-quality fiber materials to spin more high-quality yarn, so that low count hemp fiber raw materials can achieve high added value of cowboy products. The development of multi fiber blended denim yarn with multi varieties, multi-component and multi colors has strong vitality. The new summer moisture absorption and quick drying denim products endow the denim with the necessary wearing properties such as moisture absorption and quick drying in summer through the application of new materials and new technologies, and bring a new style of denim products.

According to the project leader Wuhan Textile University Chen Jun, a senior engineer, introduced that the development of new summer moisture absorption and quick drying denim products completely broke through the concept of thick traditional denim products, and proposed to make full use of the properties of filaments, apply embedded composite spinning and multi-component Sirofil spinning technology to develop the production technology of high-quality new summer denim products, which improved the moisture permeability, breathability, sweat transmission The fast drying and other wearing properties endow the fabric with a new style of soft, smooth, shiny and good drapability.

The scientific research team creatively researched, developed and improved the required production equipment according to the technical requirements for the development of new summer denim products, and developed relevant production equipment, providing a guarantee for the realization of high-quality summer denim products. In order to realize the spinning principle of the above new denim products, the team studied the production technology of denim products. The spinning reduced three processes, greatly reduced the production cost, and realized the efficient production of high-quality denim products.

The project creatively developed the hydrophilic finishing technology of denim fabric, which combines the moisture absorption of cotton fiber with filament Combined with the moisture conductivity of, it improves the functionality of moisture absorption and quick drying of denim clothing fabrics, and realizes clean, green and environmentally friendly production.

　 Sizing realizes PVA free sizing weaving

The traditional spinning and weaving theory has high energy consumption, long process, large floor area and high equipment requirements, while the new denim production technology highlights the characteristics of high quality and short process, less equipment investment, power saving, less labor, and reduced production costs. Therefore, the product has obvious price advantages and strong market competitiveness; At the same time, it also meets the requirements of national low-carbon economy, energy conservation and environmental protection. The trial spinning development of new denim composite yarn has promoted and promoted the development of multi-component, multi-functional embedded new summer lightweight denim products. It really realizes the PVA free sizing and weaving of yarns, eliminates the singeing process, and the cloth surface is still smooth and clean, and the fabric does not need mercerizing. This process method is not only in line with the production and development of non cotton fibers advocated by the state, but also in line with the development requirements of green environmental protection.

It is worth mentioning that the introduction of filament into the new summer moisture absorption and quick drying denim products has greatly increased the strength of the yarn, and the yarn structure is compact, greatly reducing the yarn Hairiness is conducive to the stability of product use. Therefore, compared with other traditional spinning technologies, it has incomparable superior performance in terms of product quality. At the same time, the wearability of the fabric is improved. The developed summer denim fabric can fully meet the needs of downstream customers in terms of innovation and applicability. According to the evaluation standards for the moisture absorption and quick drying performance of textiles, the fabric is tested for water absorption, dripping diffusion time, water evaporation rate and other indicators before and after washing to make its moisture absorption and quick drying meet the requirements of functional fabrics, and meet the consumer's requirements for the moisture absorption and quick drying of summer denim products.

It is reported that the production technology of new summer moisture absorption and quick drying denim products has formed a complete production line of new summer denim products in Shandong Dayin Textile Group Co., Ltd., successfully popularized and applied in the company's spinning and denim weaving industrialization, and formed a new series of summer denim products. Many downstream customers have placed orders. At present, Daiyin has formed a production capacity of 10000 ingots, with a total sales revenue of 303.05 million yuan and a total profit of 59.4 million yuan. New summer denim products adapt to the development of today's market and the requirements of consumers. The fabric style is unique and has strong competitiveness. The product is particularly suitable for making jeans, skirts shirt , shorts and other summer clothing. Good economic benefits play an important role in demonstrating and promoting the optimization and upgrading of denim product structure.

The mechanism of production, learning, research and application is indispensable

It is understood that since 2010, Shandong Dayin Group has taken the initiative to contact Wuhan Textile University for research on jeans production technology in order to meet the needs of enterprise development. Chen Jun has visited the company many times and pointed out that there is a great contradiction between people's preference for jeans and the single function of traditional jeans, It is also proposed that the development of new summer moisture absorption and quick drying denim products is the technology needed to solve people's summer denim clothing. After sufficient technical research in the early stage, Shandong Dayin Group and Wuhan Textile University both believe that the development of new summer moisture absorption and quick drying denim products has broad prospects, and the cooperation between the two sides in production, education, research and application has thus been launched.

The project is mainly undertaken by Shandong Daiyin Textile Group Co., Ltd. and Chen Jun of Wuhan Textile University. In the research process of the project of "Development and industrialization of new summer moisture absorption and quick drying jeans", both parties try their best. Shandong Daiyin mainly undertakes the raw materials, equipment, production tasks and market promotion tasks required for the research, Chen Jun is responsible for the technical guidance required for research and development. In the subsequent research process, Shandong Daiyinhua spent a lot of manpower and material resources on hard research, and finally under the mechanism of industry university research cooperation, the project of "development and industrialization of new summer moisture absorption and quick drying cowboy products" was successful, and the technical level reached the domestic leading level.
