Development Trend Of Rayon Flame Retardant Fabric Viscose Fiber

The application of flame retardant viscose fiber in our country is still in its infancy. It is necessary to learn from and learn from foreign developed countries.

Flame retardant viscose fiber raw materials manufacturers need to improve the level of technical services to guide downstream users to master and use technology.

Our country

Some standards have been worked out in the combustion test method, but they are not perfect enough. There is a gap between the standards and regulations of the flame-retardant products and the developed countries.

With the improvement of people's living standards and the continuous improvement of fire retardant fabric regulations, the development of flame-retardant textiles will continue to expand. The flame retardant viscose fiber will become a new favorite in the market due to its permanent flame retardancy, comfort and melting characteristics.

Flame retardant viscose fiber is regeneration.

Cellulose, which is an inexhaustible renewable resource in nature, is the first abundant natural polymer non oil resource in the plant world. It will have a longer life cycle.

With the development of technology, the technical level of cellulose fiber production will make great progress. Applying new technology to the production of flame retardant fiber, improving the physical and mechanical properties of flame-retardant fibers, especially improving the strength and wet modulus of flame retardant fibers, will open up new ways and means for flame retardant fiber and dimensional production.

The advantage of flame retardant viscose fiber is obvious. Is there any shortage in the field of flame retardancy? How can your team solve these problems?

Flame retardant viscose fiber mainly faces two problems: first, the fiber structure: the main physical and mechanical properties of viscose fiber. Because of the addition of flame retardants, the dry breaking strength and the wet strength cracking strength of the viscose fiber have a certain decline. Although the process is adjusted in the spinning process, the strength of the fiber is still lower than that of the similar products abroad, which limits the application of the flame retardant viscose fiber in some fields.

The two is the wet modulus of flame-retardant viscose fiber: the biggest drawback of viscose fiber is that the biggest drawback of ordinary viscose fiber is low wet modulus, and the same wet modulus of flame retardant viscose fiber is also low. Therefore, it is necessary to focus on improving wet modulus technology, improving viscose fiber crystallinity and orientation degree, tackling high wet modulus fiber key technology, adopting high wet modulus viscose fiber production technology, improving the wet modulus of flame retardant viscose fiber, and widening the application field of flame retardant viscose fiber.

As a manufacturing enterprise, how do you think docking between upstream and downstream enterprises can make technology achievement better and commercialization?

In our country, the development of flame-retardant textiles has just started, and it is not mature in R & D, production and market. It is also necessary to combine powerful research institutes and fibers, yarns, fabrics, clothing and other enterprises to play the role of the industrial chain, and form an industrial technology alliance to promote the healthy development of the industry.
