Problems solved by technology

[0002] With the progress of society, the chemical fiber industry has developed greatly, and people's requirements for chemical fiber products are getting higher and higher. However, the elastic fiber with spandex as the core has many shortcomings that need to be improved. Chlorine bleaching, not easy to shape, unstable elasticity, difficult to take care of, easy to foam
At the same time, the raw materials of light-shielding elastic fibers on the market are complicated, the price is high, and the elasticity is insufficient, which is not conducive to the market promotion of light-shielding elastic fibers

Abstract

The invention discloses a high-elasticity extinction TSF composite fiber chip fabric which is characterized in that the high-elasticity extinction TSF composite fiber chip fabric is made through extrusion, metering, yarn recombination, filament spraying, cooling, oiling, stretching and shaping, and winding of an extinction PTT constituent melt and an extinction PET constituent melt; the ratio of the extinction PTT constituent to the extinction PET constituent is 6:4-4:6; the extinction PET constituent contain PET and ash; the ratio of PET to ash is 98:2; the extinction PTT constituent contains PTT and ash; and the ratio of PTT to ash is 98.5:1.5. According to the invention, elasticity of the high-elasticity extinction TSF composite fiber chip fabric can be enhanced; certain light shielding effects can be achieved; production efficiency and production quality can be increased; and production cost can be reduced.

Description

technical field [0001] The invention relates to a long fiber, in particular to a high-elastic extinction TSF composite fiber chip spinning and a preparation method thereof. Background technique [0002] With the progress of society, the chemical fiber industry has developed greatly, and people have higher and higher requirements for chemical fiber products. However, the elastic fiber with spandex as the core has many deficiencies that need to be improved. Chlorine bleaching, not easy to shape, unstable elasticity, difficult to take care of, easy to foam. Simultaneously, the raw materials of light-shielding elastic fibers in the market are complicated, the price is high, and the elasticity is insufficient, which is unfavorable for the market promotion of light-shielding elastic fibers. Contents of the invention [0003] The purpose of the present invention is to provide a high elastic matting TSF composite fiber chip spinning and its preparation method. By using the produc...
