Viscose staple fiber into alternative cotton optimal period

Due to the dual impact of concentration release of viscose production capacity and economic superposition after 2010, viscose staple fiber continues to be in the doldrums and oversupply is the core contradiction in the current industry. The cotton under the protection of the national collection and storage policy maintained a high of 1.9 million yuan / ton to 20,000 yuan / ton, the spread of viscose and cotton is also from positive to negative, the huge price difference makes the domestic and foreign cotton spinning market appear Some alternative needs, therefore, viscose staple fibers enter the optimal period for replacing cotton.

First, the spread between viscose staple fiber and cotton is from 2,500 yuan/ton to 3,500 yuan/ton, and this year's negative difference is 5,500 yuan/ton (18,000 yuan/ton to 12,500 yuan/ton). The viscose can replace cotton. We will significantly improve the cost pressures on cotton textiles and ease the textile industry difficulties caused by China's high cotton prices.

Second, from the basic performance point of view, viscose staple fiber is a kind of fiber closest to cotton, derived from natural cellulose, and has the characteristics of easier dyeing, no impurities, good spinnability, skin-friendly and so on. The general cotton spinning equipment can spin spunbonds after slight adjustment of the process, and it is also the most similar fiber in the cotton spinning process, and has the advanced function replacement.

Thirdly, from the perspective of downstream products, the main blended yarns, polyester/cotton, can be completely replaced by polyester and viscose, and proper addition of a certain proportion of viscose in pure polyester, pure nitrile and other purified fiber yarns can effectively improve the comfort of textile products. , skin-friendly and breathable. In addition, the blending of cotton and viscose can effectively improve the smooth feel of the yarn, improve the dyeing fineness, and achieve the complementary advantages of the fiber.

In fact, the viscose staple fiber in the domestic market has maintained a demand growth of around 10% a year since 2009, while the consumption of cotton has instead decreased slowly. This also proves that viscose staple fiber has always been an alternative to cotton. However, it should be noted that this substitution is natural and disorderly and basically a result of downstream choices. The promotion of viscose enterprises is weak and unorganized. In particular, there has been a marked slowdown this year, reflected in the slowdown in the demand for viscose staple fibers. From January to March, the apparent demand for viscose staple fibers was 680,000 tons, which was 650,000 tons in the same period of last year. The yarn slow-moving prices continued to decline. At present, the national viscose staple fiber production capacity is close to 3.7 million tons. Compared with the consumption of 10 million tons of cotton per year, if we can further expand the share to 5%, we will be able to drive the demand for 500,000 tons of viscose staple fiber. Therefore, for the viscose staple fiber industry, how to seize the current golden opportunity for alternatives and organically promote alternative cotton work is an effective way to address the status quo of viscose staple fiber in the short and medium term.

The following work should be done at present.

First, as soon as possible through the collaboration of the viscose staple fiber industry and the cotton spinning industry, promote the transformation of the traditional cotton spinning industry, increase the application and promotion of viscose staple fiber in the cotton spinning industry, and increase the viscosity ratio in the cotton spinning industry; second, the viscose staple fiber industry The alternative cotton should be planned as a medium-term strategy. We must learn from the development concept of “Yanmian”. We must organize and plan the fiber research in a targeted manner, optimize the physical properties of the fiber, make it more alternative, and develop alternative cotton. Simulated viscose staple fiber; Third, viscose staple fiber replaces cotton to guide and promote the use of viscose from the downstream product development, such as some blended products, trouser fabrics, tooling fabrics, knitted sweaters for spring, summer and autumn. Denim fabrics and so on; Fourth, viscose staple fiber to strengthen the promotion and promotion of the cotton textile industry chain, organized to promote the popularization and service of spunbond technology.

For the viscose staple fiber industry, how to seize the strategic adjustment period of value replacement and functional replacement, and play its bio-based characteristics as quickly as possible, and promote accelerated replacement of cotton should be an effective way to solve the short-term viscose staple fiber production capacity difficulties.
