Most of the antibacterial and deodorizing materials used in underwear products are extracted from metal ions or chemical raw materials. These materials, while having antibacterial properties, often pose certain hazards to the human body, and their performance will also weaken after multiple washes. Can this material be extracted from natural items that are more beneficial to the human body?
"We extract a component called chitosan from shrimp and crab shells and make chitosan fiber blended fabric." " On October 13th, Yi Hongjun, a new materials research and development engineer at Qingdao Jifa Group Co., LTD. (hereinafter referred to as Jifa), told reporters that the "Marine biological chitosan fiber" they have developed is an antibacterial and deodorizing functional material extracted from Marine organisms.
As a traditional industry, the textile industry was once labeled as having low technological content. Founded in 1955, Jifa has grown from a small textile workshop into a private textile enterprise "carrier" with an annual sales revenue of over 10 billion yuan, becoming a leading enterprise in China's knitting industry and a chain leader in Qingdao's textile and garment industry. With technological innovation, it is gradually subverting people's perception of this industry. As Yang Weidong, the chairman of Jifa, said, high-tech should not specifically refer to certain industries. Through continuous technological innovation and cross-border integration, high-tech enterprises can also grow in the traditional textile and garment industry.
Material innovation and fabric innovation
It is reported that "Marine biological chitosan fiber" is a fiber material extracted from natural organisms, which has the functions of antibacterial, deodorizing, hemostasis and promoting healing. It has good biological safety and biocompatibility and has won the second prize of the National Science and Technology Progress Award.
Chitosan fiber fabric, which is made through processes such as spinning, weaving, setting and dyeing, has superior functionality and comfort compared to cotton products and can rival cashmere and silk. Its antibacterial rate against Escherichia coli, Staphylococcus aureus and Candida albicans reaches 7A level.
Chitosan fibers are currently widely used in medical dressings, textile and garment, military supplies and other fields. Yi Hongjun introduced that nonwoven fabrics made from Marine biological chitosan fibers have been widely used in the field of medical dressings. Compared with traditional cotton gauze, they have remarkable hemostatic and analgesic properties. They can absorb exudate in a gel-like form, clean wounds without adhesion, maintain a moist and favorable healing environment for the wound surface, and shorten the healing time.
Not just shrimp and crab shells. On the verge of development, straw, old corn grains, and even mineral water bottles have all been developed for use as new types of fiber materials.
With the improvement of people's living standards, they have put forward higher requirements for clothing, and green and environmentally friendly fabrics are increasingly favored. The Jifa Intelligent Spinning Factory mainly produces high-end, differentiated and multi-functional fiber material yarns, filling the gap in the production of new fiber yarns in Qingdao.
For the textile industry, materials are fundamental and fabrics are key. Jifa has long been committed to the development of environmental protection, green and sustainable development, as well as the research and application of new functional textile materials, technologies and equipment. Every year, it develops over 1,000 new fabrics and carries out nearly 100 innovative projects.
