Embodiment 1

[0043] The preparation method of the anti-shrinkage and non-ironing wool-like fabric, its process is as follows:

[0044] (1) Preparation of wool-like mixed fiber yarn:

[0045] Wool-like mixed filaments are extruded on spinneret I and spinneret II;

[0046] On spinneret I, PTT melt (intrinsic viscosity is 1.04dL / g) is directly extruded after distribution, and POY filaments are obtained according to POY process (spinning speed and spinning temperature are the same as FDY); spinneret I The spinneret hole on the top is circular;

[0047] At the same time, on the spinneret II, the PTT melt (intrinsic viscosity is 1.04dL / g) is divided into two paths: one path is directly extruded after distribution; the other path is together with PET melt (intrinsic viscosity is 0.51dL / g) Extrude after distribution according to the parallel composite spinning method; The ratio of the number of spinneret holes n (circular spinneret holes) flowing through is 1:10; the ratio of the equivalent dia...

Abstract

The invention relates to a shrink-proof and easy-care wool-like fabric and a preparation method thereof. After sizing, warping and weaving according to the texture and weaving requirements of knitted fabrics to obtain wool-like fabrics, the wool-like fabrics are sorted to obtain anti-shrinking and non-ironing wool-like fabrics. Wool-like fabric that shrinks and does not need to be ironed; the yarn is composed of wool-like mixed fiber yarn, nylon fiber and wool fiber; the preparation method of the wool-like mixed fiber yarn is: on the spinneret 1, PTT melt is extruded to obtain POY yarn ; On the spinneret II, the PTT melt is extruded in one way (the spinneret m); the other way is extruded with the PET melt in a parallel composite spinning mode (the spinneret n) to obtain the FDY filament; On the silk plate II, the ratio of the number of spinneret holes m to the number of spinneret holes n is 1:5-10; it is made by combining POY yarn and FDY yarn and combining them with a network; the final anti-shrink and non-ironing imitation The curling directions of the monofilaments in the wool-like blended yarns in the wool fabric are randomly distributed. The invention solves the problem that the dimensional stability of wool-like fabric products is difficult to control.

Description

technical field [0001] The invention belongs to the technical field of polyester fibers, and relates to a shrink-proof and non-ironing wool-like fabric and a preparation method thereof. Background technique [0002] In the design of wool-like fabrics, polyester multi-composite and different-shrinkage filaments are usually selected. In the literature (Research on the wearability of PTT / PET composite filament wool-like fabrics [J]. Woolen Technology, 2006 (10): 57-59.) The characteristics of PTT / PET composite filament wool-like fabrics are expounded, and the basic wearability of PTT / PET composite filament fiber wool-like fabrics is tested with reference to ordinary wool-like fabrics and pure wool fabrics. According to the analysis, the softness of PTT / PET composite filament wool-like fabric is similar to that of pure wool fabric, and it has better elastic recovery and wrinkle recovery. However, in the above-mentioned wool-like knitted fabric, because it contains a part of woo...
