Development trend of phosphorus flame retardant fabric viscose fiber
Moderator: What problems does this fiber encounter in its market application? What is its development trend?
Xia Lvcong: The application of flame-retardant viscose fiber in my country is still in its infancy, and we need to learn from the application technology of developed countries abroad. Flame-retardant viscose fiber raw material manufacturers need to improve their technical service levels and guide downstream users to master and use the technology.
my country has formulated some standards for textile combustion test methods, but they are not perfect enough. In terms of flame retardant product standards and regulations, there is a gap compared with developed countries and need to be improved and implemented.
As far as the development trend of flame-retardant viscose fiber is concerned, with the improvement of people’s living standards in our country and the continuous improvement of flame-retardant fabric regulations, the development of flame-retardant textiles will continue to expand, and flame-retardant viscose fiber has permanent Flame retardancy, wearing comfort and non-drip characteristics will become the new favorites of the market, and the fields of civilian and military use will continue to expand.
Flame-retardant viscose fiber is regenerated cellulose fiber, and cellulose is an inexhaustible renewable resource in nature. It is the most abundant natural polymer non-petroleum resource in the plant world. It will have more applications. long life cycle.
With the increase in technology research and development, the level of cellulose fiber production technology will make great progress. New technologies will be applied to the production of flame-retardant fibers to improve the physical and mechanical properties of flame-retardant fibers, especially the strength of flame-retardant fibers. and wet modulus, which will open up new methods and approaches for the production of flame-retardant fibers.
Moderator: The advantages of flame-retardant viscose fiber are obvious. Are there any shortcomings in the application of this fiber in the flame-retardant field? How does your team solve these problems?
Xia Lvcong: Flame-retardant viscose fiber mainly faces two problems: First, in terms of fiber structure: the main physical and mechanical performance indicators of viscose fiber have a certain decrease in dry breaking strength and wet cracking strength due to the addition of flame retardants in the blend. , although the process has been adjusted during the spinning process, the fiber strength is still lower than similar foreign products, which limits the application of flame-retardant viscose fiber in some fields.
The second is the wet modulus of flame-retardant viscose fiber: the disadvantage of ordinary viscose fiber is its low wet modulus. Similarly, the wet modulus of flame-retardant viscose fiber is also low. It is necessary to focus on the research on the process method of improving the wet modulus and improving the viscosity. The crystallinity and orientation of viscose fiber, overcome the key technologies of high wet modulus fiber, adopt high wet modulus viscose fiber production technology, improve the wet modulus of flame retardant viscose fiber, and expand the application fields of flame retardant viscose fiber.
Full development requires enterprise alliance
Moderator: As a manufacturing enterprise, how do you think upstream and downstream enterprises can connect so that technological achievements can be better industrialized?
Xia Lvcong: In our country, the development of flame-retardant textiles has just started and is not yet mature in terms of R&D, production, and market. It is even more necessary to unite powerful scientific research institutions and fiber, yarn, fabric, clothing and other enterprises to play a more important role. The role of the industrial chain is to form an industrial technology alliance and promote the healthy development of the industry.
