Key Technology Breakthrough Of Hemp Blended Knitted Fabric Development

The development of biomass economy has become an inevitable need! Functional textile learned: Recently, Fujian Fengzhu Textile Technology Co., Ltd. won the innovation contribution award of knitted underwear of China Textile Industry Federation for its "key technology and industrialization of hemp blended knitted fabric development".

Zhang Xin, director of Fengzhu textile technology, told reporters that in recent years, the global demand for "green" environmental protection is growing. Therefore, people gradually realize that the development of renewable biomass resources and the development of biomass economy has become an inevitable need. The comprehensive research and development of industrial hemp fiber meets this need. Zhang Xin, chief technical officer of Fengzhu Textile Co., Ltd., "industrial hemp fiber is mainly used in clothing that contacts with human skin, known as" the second skin of human body ". The hemp fiber has good comfort, at the same time, it also has excellent functions of anti mildew, antibacterial, moistening and skin nourishing, and can also avoid skin pricking due to static electricity.

Because hemp fiber has good moisture absorption and permeability, fast heat dissipation and moisture dissipation, good drapability, antistatic, anti ultraviolet, soft and smooth, no itching and other functions, therefore, in the hot summer, wearing hemp clothing will not feel as stuffy as wearing chemical fiber fabrics, nor will it feel sticky like wearing cotton, silk and other natural raw materials clothing when sweating, but let people feel transparent Cool

Zhang Xin said that in today's consumer trend of "returning to nature and returning to nature", the development of underwear with good comfort, functionality and health care will certainly be favored by the majority of consumers.

In order to solve the problem of poor cohesion and spinning difficulty of industrial hemp, the fine processing process is more complex and the textile dyeing and finishing process is difficult. Fujian Fengzhu Textile Technology Co., Ltd. cooperates with the Textile College of Donghua University to jointly develop hemp blended knitted fabrics with excellent antibacterial properties, moisture absorption, air permeability, softness, comfort and healthy ecology by using its patent research results and postgraduate master's thesis knowledge, so as to promote industrial hemp knitted fabrics in the civil market.

Zhang Xin told reporters that the project uses cotton, viscose, hemp blended yarn as raw materials, ingeniously combines the characteristics of three kinds of fibers: excellent natural antibacterial performance, good moisture absorption and permeability, soft and comfortable functions. The fabrics produced by the optimized dyeing and finishing process make full use of the respective characteristics of cotton, viscose and hemp: good moisture absorption and permeability, good drapability, antistatic and anti ultraviolet Thread, soft and smooth, anti mildew and sterilization. The fabric has the natural and simple appearance style of hemp fabric, and does not produce the prickle feeling similar to other hemp fabrics. It is comfortable, soft, beautiful and excellent wearing performance, especially suitable for the selection of underwear clothing fabric.

Zhang Xin, chief technical officer of Fengzhu Textile Co., Ltd., we have improved the strength, wool effect, whiteness and handle of the fabric by changing the traditional pretreatment process. The screening and research of dyeing dyes has solved the problems of uneven color on cloth surface and white star in production, improved product quality, saturated color, elegant and solemn color, natural and simple, thus achieving our design requirements of "returning to nature and returning to nature."

Zhang Xin said that through the research on key dyeing technology of Fengzhu textile, the influence of dyeing temperature, time and heating rate on dye uptake and levelness was compared, and the dyeing process was determined to maximize the essential characteristics of cotton, viscose and hemp.

This project was initiated and developed in June 2017. With the active cooperation of various departments, the project fabric development and fabric performance index testing will be completed in 2018.

At present, Fengzhu textile has realized mass order production, and the fabric design can be widely applied to indoor, outdoor, children's, middle-aged and elderly underwear, leisure, sports and health care and other clothing fabrics, and has brought economic benefits for two consecutive years. Among them, the new profit will be 14.5 million yuan in 2019 and 10.6 million yuan in 2020.

In addition, the project has great social benefits.

Zhang Xin told reporters that the cotton / viscose / hemp fiber blended fabric developed by the project can replace some high-end underwear knitted fabrics, and solve the problem of high-end underwear fabric price, which ordinary consumers can't afford, so that more people can enjoy the comfort, functionality and health brought by high-grade fabrics. To promote the sustainable and healthy development of China's textile industry is also of positive significance to social and economic development. In the process of research and development of this project, the problems encountered are constantly tested, verified and solved. Finally, the best technology of cotton / viscose / hemp fiber blended fabric is obtained, which makes a certain contribution to the progress of science and technology.
