Recently, Shandong Huafang Co., Ltd. held an expert appraisal meeting on the project of "dyeing and finishing seaweed fiber woven fabric and its industrialization" and passed provincial appraisal. As one of the earliest companies to research and develop seaweed fiber fabrics, the adoption of this appraisal also affirmed the company's efforts in the area of ​​seaweed fiber fabric dyeing and finishing for several years. It is understood that the project by Huafang shares and Shandong Binzhou Textile Research Center and other units to carry out cooperation, completed by the Qingdao six cotton fiber procurement and textile weaving process, Huafang shares from the fabric dyeing and finishing processing. According to the appraisal result, the dyeing and finishing technology determined by this project is in the advanced international level. Pretreatment process patent seaweed fiber is extracted from natural seaweed material spinning processing, as raw materials from natural seaweed, seaweed fiber has good biocompatibility, biodegradable absorbability and other special features, is a new green-green One of the representatives of fiber. Huafang Co., Ltd. as early as the end of 2006 has successfully developed a seaweed fiber fabrics, the "seaweed fiber pre-treatment process" in 2007 to apply for and received the national patent. The process is a new type of pre-packaging process that adds desizing and peracetic acid to the fabric in order to handle the fabric completely and to protect the fiber function and strength from damage. During the entire processing, all drying steps The use of pine drying, to ensure the quality of the fabric and the unique function of seaweed fiber fabrics, seaweed fabric metal cations, alginate will not be lost. According to Li Xijun, director of research and development of Huafang Co., Ltd., this pretreatment process can ensure that the antimicrobial properties of seaweed fiber will not be lost. In the subsequent dyeing and finishing process, its physical properties and physical indexes are not damaged, A one-step dyeing and finishing process gives a good dyeing or bleaching effect. According to the company's characteristics of seaweed fibers, in the subsequent dyeing and finishing process using green processing technology, dyes, additives are used to achieve the national standard of environmentally friendly products. In order to obtain the glossiness and improve the ability of the fabric to absorb the dye, improve the quality and stability of the product and reduce the shrinkage rate, Huafang treated the semi-finished seaweed fiber fabric by mercerization and selected reactive dye to achieve excellent fastness and uniformity Dyeing performance. Seaweed fiber fabric to be name 15 years ago, has been engaged in related research professor of Qingdao University, Zhu Ping is one of the sponsors of seaweed fiber research. Last year, he assumed "seaweed antibacterial fiber development and performance research" passed by the Shandong Provincial Science and Technology Department of Experts Committee identification. Due to work reasons, originally invited to attend the Huafang "seaweed fiber woven fabric dyeing and finishing industrialization research" project appraisal will eventually Professor Zhu Ping did not take place. During the interview, he gave a high appraisal of this project of Huafang Corporation. However, Professor Zhu Ping believes that there is a conceptual misunderstanding in the field of research and application of seaweed fibers in China and the need for standardized naming. The United States Chemical Abstracts (CA) has pointed out: a substance containing a variety of components, when a single component content of more than 15%, the name of the component can be used as the substance name. Zhu Ping said that sodium alginate as a raw material spun high strength pure seaweed fiber used in the field of industrial textiles, because of its excellent antibacterial and flame retardant properties, it can be used as medical coatings and automotive interiors. However, since pure seaweed fiber is not alkali-tolerant, if it is made into clothes, it swells during the washing process. Therefore, the seaweed fiber needs to be modified to have the functions of alkali-resistance and dyeing performance. Currently engaged in seaweed fiber bedding products, apparel production and development of enterprises, most are based on alginate blend modified Tencel or viscose fiber, sodium alginate fabric only accounts for 5% to 10% . He believes that this fabric should be referred to as alginate (sodium) modified viscose or Tencel fibers, and seaweed fiber fabrics there are some differences. It is understood that the fabric Huafu Stock Co., Ltd. belongs to the sodium alginate and Tencel blended, sodium alginate accounts for about 10%, so strictly speaking, alginate modified Tencel fiber fabric. Gradually clear the road to industrialization Professor Zhu Ping revealed that he is engaged in Wuhan Institute of Science and Technology algae fiber composite modification study so that it can be applied to apparel and other end products, there are already Hubei, Sichuan and other places on the seaweed fiber clothing industry The project showed strong interest and demanded to carry out industry-university-research cooperation. However, whether it is pure seaweed fiber fabric, or alginate-modified blended fabric, represent the development of new environmentally friendly functional fabrics, but also the application of technology in the textile printing and dyeing industry. From a practical point of view, the successful development of seaweed fiber woven fabrics and good marketing, indeed Huafang brought economic benefits. Weifang Jia Textile Co., Ltd., Shanghai Mao Yuan Garment Co., Ltd. and other companies in the use of Huafang algae acid modified blends of fiber fabrics, all of the fabric good elasticity, comfort and antibacterial skin care function expressed satisfaction. Huafang company algae acid modified blended fabric industrial network is gradually rolled out. (Chen Xiaojing)
