Not long ago, the "1000 tons of twist free composite spinning key technology project" supported by Beijing science and technology commission, Beijing dongtu fuxing clothing co., ltd. and Beijing dongtu times spinning co., ltd. passed the acceptance test.
According to the expert group of the municipal science and technology commission, "no-twist composite spinning technology is a major technical breakthrough in traditional spinning technology. The comprehensive utilization rate of textile raw material resources and the comprehensive performance of yarn are improved. This is a unique result of basic innovation in China's textile industry and a revolution in spinning technology. The introduction of this technology also enables China to lead the world in spinning technology, which helps to promote the upgrading of the local textile industry.
No-twist composite spinning is a new spinning process. The theory of twistless spinning which was put forward in the last century has become a reality through the key technologies of fiber lamination and adhesion. The technology enables the recombination of existing textile fibers, the spinning of free twist from zero twist to normal twist, and the establishment of a complete textile design system. Twist - free composite spinning is widely used. By adjusting the size of the inner and outer fibers, the enveloping ratio, the elasticity of the core yarn and the twist of each layer, a new type of twistless composite textile with unique style is formed.
Beijing dongtu times spinning co., ltd. is the contractor of this project, and has conducted in-depth research on non-twist composite yarn at both technical and market levels. To meet the market demand, the merino wool double-bale single-ply weakly twisted stretch yarn, cotton modal single-bale double-ply ultra-weakly twisted yarn, mulberry cashmere double-bale single-ply yarn and cotton bag yarn were developed. Cotton super weak twist yarn. According to the requirements, the company has completed the research on the production technology of the system, broken through the key technology of coating adhesion of non-twist composite yarn, and mastered the technological process required for 1000 tons of non-twist composite yarn. The world's first no-twist composite yarn production line has been built, and the enterprise standard of no-twist composite yarn has been established.
