Embodiment

[0031]Produced on the Murata (MUTATEC) 33H (S+Z) machine, the sea-island yarn POY of 150dtex / 36f*37I specification is used as the first raw material yarn A, and the 150dtex / 36f round polyester cationic POY is used as the first raw material yarn B. The two bundles of filaments are drawn out from the original wire frame, separated and sequentially passed through the first double cutter 1, the first micro-moving filament guide 2, and the first wire feeding roller 3, and then enter the first hot box 4. The filament in the box 4 is subjected to 1.84 times the stretching of the second wire feed roller 11 (the draw ratio is generally 1.5-2.2) and The twisted deformation of the torsion transmitted from the false twister 8 has the characteristics of a textured yarn. Guided by the skid wire guides 5 and 6, the cooling plate 7 cools down to reduce the temperature of the filaments, and then enters the false twister 8 for false twisting. 115 degrees), the contact pressure of the apron is ...

Abstract

The present invention discloses the production process of composite wool-like polyester filament yarn. Very fine sea island polyester fiber and conventional polyester fiber are stretched, false twisted and combined to form composite fiber filament, and the composite fiber filament is then combined with high shrinkage polyester fiber with boiling water shrinkage over 20 % via air spray twisting to form the composite wool-like polyester filament yarn. The composite filament yarn is woven, and processed through fiber opening, post finishing and light roughing to form soft and fine wool-like fabric with excellent rebound resilience.

Description

technical field [0001] The invention belongs to a production process of polyester composite filaments, in particular to a method for manufacturing wool-like polyester composite filaments. Background technique [0002] Wool-like polyester filament products are now common in the market. The conventional manufacturing method is to combine polyester filaments with different properties (cationic dyeability, color, special-shaped cross-section, different shrinkage, different single-filament deniers but the smallest) according to the requirements of the fabric. The fineness of the single filament is greater than 0.3D, etc.), through the jointing of the network machine or through the deformation treatment of the false twister or the air texturing machine, to prepare the blended yarn to obtain the style of the woolen fabric, and also to combine FDY and POY in the spinning process Or compound FDY with different properties to produce three different polyester wool-like filaments with d...
