Market Development And Application Of Green Flame Retardant Viscose Fiber

In recent years, China's viscose staple fiber expansion expansion, coupled with the financial crisis of the European Union as the representative of the fourth quarter of 2011, has swept the globe, the economy has obviously declined, and the market demand has declined sharply. Spin Industry has brought unprecedented impact. At present, upgrading and upgrading viscose fiber products in China is imminent.

Domestic and foreign viscose fiber enterprises have consensus on upgrading products, but the intensity and effect are quite different: Lenzing Co has said that it will invest 130 million euros to build Tencel fiber factory locally, and its production capacity of Tencel fiber will increase by 67 thousand tons after commissioning. In addition, it will expand the production of Lan Jing modle and Lan Jing FR.

In China, based on the successful development of phosphorus flame retardant viscose fiber, Jilin chemical fiber has developed a coloured flame-retardant viscose fiber which is mainly composed of a black system and a variety of color systems. According to the introduction, the flame retardant viscose fiber of Jilin chemical fiber is developed on the basis of DXL1212, a proprietary phosphorous flame retardant agent with independent intellectual property rights. Shandong Silver Eagle Chemical Fiber Co., Ltd. successfully completed the transformation and upgrading of an industrial production line in 2011, enabling it to have the annual production capacity of 15 thousand tons of flame retardant viscose fiber.

From the current domestic and international flame retardant viscose fiber, Shandong Silver Eagle Chemical Fiber Co., Ltd. uses the silicon nitrogen compound flame retardant produced by Xinxiang Changhong Chemical Co., Ltd., the flame retardant viscose fiber developed has more green environmental protection performance, and its future market prospect is bigger. Although the phosphorus flame retardant viscose fiber is accepted by the market, there will be doubts and concerns about its odor smoke and green environmental performance in the future.

Silicide frc The development and production are different from other products such as matting and so on. It is a revolutionary change in the production process of products, and we need to think and design the whole process of production.

First of all, the main problem in development is not the effect of flame retardancy, but more importantly, the implementation of the process requires specific supporting facilities and technologies, including the settlement of flame retardant in containers and pipes, the deactivation of nitride, etc. Although it is more difficult in actual production, it is a necessary process.

The quality index of viscose has changed greatly due to the increased number of organic silicides in viscose component than that of viscose. The same linear density, compared with ordinary viscose fiber, the actual diameter of flame retardant viscose fiber is much smaller, which in fact increases the difficulty of production. How to provide uniform and suitable viscose for spinning is very important, and also has great influence on the replacement cycle of spinneret components. The problem of filament strength is one of the keys to the smooth process of subsequent textile processing, and also the key to the product as a textile material.

Secondly, after the silk contains flame retardant ingredients, the surface structure and the overall structure of the silk have undergone great changes. To achieve the desired effect of oil, not only the oil with stronger softness, inclusion and smoothness is needed, but also more intensive oil processing control and measures are needed to ensure better follow-up value of the product. In other words, silicone flame retardant viscose fiber needs special finishing technology and finishing agent.

At present, the time for large-scale production of silicide flame retardant viscose fiber is almost mature, and it can produce coloured flame-retardant viscose fibers of various colors. But in terms of market promotion and scale production, fiber enterprises still have a lot of misgivings. The main reason is not the flame retardant technology itself, but the optimization of production process is somewhat difficult, and the corresponding technical measures and management methods need to be re established. The use of flame retardants and other high prices, higher production costs, making the production enthusiasm of enterprises is not high. The technology of silicide flame retardant viscose fiber production needs to be further optimized and refined, especially in short fibers. The market development of products is not enough, the market and customers need to improve their product awareness, and the price advantage of products is not obvious. There is a lack of coordination communication between fire retardant manufacturers and silicide flame retardant viscose fiber production enterprises, and the time to solve the problem of large-scale production is lagging behind.

In addition to the irregular shape of the cross section, the flame retardant viscose fiber is also safe and non-toxic. It can naturally degrade into the soil composition. It has high flame retardancy, good self extinguishing effect, washable and chemical treatment, good moisture absorption and breathability, and better far-infrared performance. It is more warm than ordinary fiber.

After adding flame retardants into the silk, the proportion of the dry wire itself has changed. It has not been applied according to the relationship between the fiber size and the length and the quality of the original fibers. The same quality of the 2 different fibers and the same length has great difference, which is to be considered and valued in the textile process. At present, the development and production of silicified flame retardant viscose staple fiber, which is less powerful than ordinary viscose staple fiber, and its relative elongation is relatively small, so the length of cotton products provided by the manufacturer is suitable for 40mm~45mm, and the best way is to blend with the flame retardant synthetic fiber. On the one hand, it can enhance the overall strength and workability of yarn, and on the other hand, it can also reduce the cost of products while ensuring the excellent flame retardant effect of yarn and fabric. Of course, the strength and elongation of silicified flame-retardant viscose fibers are not satisfactory. The heat shrinkability of silicide flame retardant viscose fiber products is small, and needs to be considered in weaving process.

When the flame retardant is added to the silk bar, the changes in the internal components of the product will lead to a change in its color absorption properties, and the dyeing and pigment selection and process control methods need to be changed to obtain satisfactory lasting dyeing properties. In addition, during the washing process, selective washing methods and processes are needed to maintain a durable flame retardant color performance.

In general, silicide flame retardant viscose fiber has not only a breakthrough in the production process, but also needs to be adjusted and adapted for spinning, weaving and dyeing.

For a long time, in the domestic and foreign markets, the flame retardant viscose fiber has been monopolized by some foreign enterprises because of its technical problems, so the market supply is small and the price is very high. Less mature products are recognized in the market, which greatly limits consumption and restraining the growth and development of the market, although customers and consumers at home and abroad are more interested in protecting and purchasing textile products. The key to the production and development of flame retardant viscose fiber in China is the price of flame retardants. Because of the high price of fire retardant and the high cost of production, they lose their confidence and interest, and of course, the technology and equipment of flame-retardant viscose fiber. The silicide flame retardant viscose fiber has good flame retardant effect, and is safe, non-toxic and natural degradable. It is a real green product, and it also has a lower price advantage for silicide flame retardant, so that silicide flame retardant viscose fiber products have a better sexual price advantage in the market. With the development and marketing of the enterprise, it will continuously improve customer awareness and product consensus, and the further reduction of product prices will also be accepted by the consumers.

No doubt, flame retardancy. textile The market demand will be bigger and bigger. Silicide flame retardant viscose fiber will also receive much attention in the flame retardant fiber market. Its market prospect is huge. It is the upgrading product that can be produced in large scale at present. It is also a real green flame retardant product.
