Abstract

The invention discloses a one-step composite blended fiber yarn spinning method. The one-step composite blended fiber yarn spinning method includes: subjecting PET (polyester) chips and PTT (polytrimethylene terephthalate) chips to siloing, pre-crystallizing, drying, extruding fusing and filtering to obtain fused masses of their own; subjecting the two fused masses to metering pump treatment, yarn spinning and side blowing after entering a composite spinning box; subjecting one path to bunching oiling to obtain PET filament yarn via a yarn guiding disc, and subjecting the other path to bunching and oiling to obtain PTT filament yarn via a hot roller; mixedly drafting and connecting the obtained PET filament yarn and the obtained PTT filament yarn into a net via a common wire stitching machine; and rolling to obtain composite blended fiber yarn. The one-step composite blended fiber yarn spinning method has the advantages that two different raw materials including PET and PTT are adopted to realize the one-step composite blended fiber yarn spinning method, the spinning process is in centralized control, the composite blended fiber yarn product can be directly produced one equipment set, the producing speed reaches to above 3300meters / minute, efficiency is improved greatly, product quality is stable, weight and length of the products are fixed, and weaving efficiency of downstream enterprises is improved greatly.

Description

technical field [0001] The invention relates to a textile spinning method, in particular to a composite mixed fiber spinning method. Background technique [0002] PTT and PET composite blended yarn has the comfortable feel of nylon, the bulkiness of acrylic fiber, the resilience of spandex, and the high strength and dimensional stability of polyester. The fabric of this fiber is crisp, has good dimensional stability, soft hand feeling, good resilience, anti-chlorine, anti-aging, strong anti-fouling ability and dryness of PTT fiber. It is favored by consumers and is suitable for warp knitting, spraying Water, jet and many other post-processing equipment processing. PTT and PET composite blended yarn effectively reduces the cost of the fabric, and the fabric has both properties, which has great development potential. [0003] At present, PET and PTT composite blended filaments are produced by independent spinning equipment to produce PET filaments and PTT filaments, and then...
