Problems solved by technology

[0003] At present, the popular cycle of functional products is getting shorter and shorter, which means that the cycle of differentiated products is gradually shortened, the requirements for fibers are getting higher and higher, and the flow of talents, technology, and information is smoother, and the market feedback is rapid. Any product As long as it appears, there will soon be a large number of similar products in the market, thus losing high added value

Embodiment 1

[0010] The preparation method of the plied polytrimethylene terephthalate fiber filament with cooling function uses sub-nanometer zinc oxide as an additive, wherein the mass percentage of the additive is 3.5%, and is added to the polytrimethylene terephthalate by injection. In the melt of propylene glycol formate fiber (PTT), it is made into pre-oriented yarn (POY), and then the product is processed by forward and reverse twisting (S+Z) plying for texturing.

Embodiment 2

[0012] The preparation method of the plied polytrimethylene terephthalate fiber filament with cooling function, selects sub-nanometer zinc oxide as an additive, wherein the mass percentage of the additive is 4.7%, and is added to the polytrimethylene terephthalate by injection. In the melt of propylene glycol formate fiber (PTT), it is made into pre-oriented yarn (POY), and then the product is processed by forward and reverse twisting (S+Z) plying for texturing.

Embodiment 3

[0014] The preparation method of the ply poly(trimethylene terephthalate) fiber filament with cool and cool function adopts subnano-level zinc oxide as an additive, wherein the mass percentage of the additive is 6%, and is added to polytrimethylene terephthalate by injection. In the melt of propylene glycol formate fiber (PTT), it is made into pre-oriented yarn (POY), and then the product is processed by forward and reverse twisting (S+Z) plying for texturing.

Abstract

The invention relates to a preparation method for a stranded PTT (Polytrimethylene Terephthalate) fiber filament with a cooling function. The preparation method comprises the following steps: selecting sub-nanometer zinc oxide as an additive, wherein the mass percent of the addition of the additive is 3.5%-6%; adding the additive into a PTT fiber melt in an injection mode, thereby forming a pre-orientated filament; and adding elasticity and adopting positive and negative twisting stranding method for preparing the product. The preparation method provided by the invention is suitable for the preparation of the stranded PTT fiber filament with the cooling function.

Description

technical field [0001] The invention relates to a preparation method of ply poly(trimethylene terephthalate) fiber (PTT) filament with cooling function. Background technique [0002] In the past ten years, the global high-tech textile market has been climbing rapidly, with an annual growth rate of about 4.8%, among which the growth rate of the Asian market is even greater. In the field of high-tech textiles, polyester has always occupied a large market share, and the demand is very strong. However, compared with foreign developed countries, there is still a large gap in domestic technology and product variety structure. The main surface is the prominent structural contradictions, unbalanced industrial chain development, excess production capacity of conventional products, poor new product development capabilities, and high-tech original technologies. Lag, chemical fiber differentiation rate is only about 30%, far lower than 45-50% in developed countries. At the same time, ...
