Embodiment 1

[0020] A needle punching production process for preparing wool-like knitted fabrics through wool-like silk, comprising the following steps:

[0021] (1) Using wool-like silk as raw material, it is woven with a weft knitting 1+1 double rib weave structure through a large circular machine to obtain a base fabric, in which one yarn of the rib weave is 75D / 72F polyester DTY untwisted yarn, and the other The root yarn is 120D / 144F viscose long fiber untwisted yarn, and the average length of the loops of the rib weave is 3cm;

[0022] (2) Fix the base fabric on the pre-acupuncture machine, lay the net on the front side of the base fabric and stack the short fiber layer, and perform front-side pre-acupuncture. The depth of pre-acupuncture is 4 cm, and the frequency of pre-acupuncture is 10 times / s. Short fiber is that the mass ratio of wool fiber and polyester fiber is 2:95, and the average fiber length is 4mm, and the diameter of polyester fiber is 3um;

[0023] (3) Send the base f...

Embodiment 2

[0026] A needle punching production process for preparing wool-like knitted fabrics through wool-like silk, comprising the following steps:

[0027] (1) Using wool-like silk as raw material, it is woven with a weft knitting 2+2 double rib weave structure through a large circular machine to obtain a base fabric, in which the rib weave is 200D / 288F polyester DTY untwisted yarn and 150D / 288F viscose long fiber The untwisted yarns are arranged side by side, and the average length of the ribbed loops is 4.5cm;

[0028] (2) Fix the base fabric on the pre-acupuncture machine, lay the net on the front of the base fabric and stack the short fiber layer, and perform front pre-acupuncture. The depth of pre-acupuncture is 7 cm, and the frequency of pre-acupuncture is 5 times / s. The short fiber is that the mass ratio of viscose staple fiber and rabbit hair fiber is 95:5, the average fiber length is 8mm, and the diameter of viscose staple fiber is 5um;

[0029] (3) Send the base fabric int...

Embodiment 3

[0032] A needle punching production process for preparing wool-like knitted fabrics through wool-like silk, comprising the following steps:

[0033] (1) Using wool-like silk as raw material, it is woven with a weft knitting 2+2 double rib weave structure through a large circular machine to obtain a base fabric, in which the rib weave is 100D / 168F polyester DTY untwisted yarn and 150D / 132F polyester DTY untwisted yarn The wires are arranged in phase, and the average length of the coils of the ribbed structure is 4cm;

[0034] (2) Fix the base fabric on the pre-acupuncture machine, lay the net on the front of the base fabric and stack the short fiber layer, and perform front pre-acupuncture. The depth of pre-acupuncture is 5 cm, and the frequency of pre-acupuncture is 8 times / s. The short fiber is polyester DTY untwisted yarn and the mass ratio of wool fiber is 95:5, the mass ratio of wool fiber wool and rabbit hair is 1:1, the average length of the fiber is 6mm, and the diamete...

Abstract

The invention provides a needling production process for preparing wool-like knitted fabric from wool-like filaments. The production process comprises the following steps: (1) weaving the wool-like filaments as a raw material by a circular knitting machine on the basis of an interlock stitch structure to obtain base fabric; (2) fixing the base fabric on a pre-needling machine, laying a net on thefront of the base fabric and stacking a short fiber layer for front pre-needling; (3) feeding the base fabric into a main needling machine for front needling; (4) blanching the needled semi-finished fabric to level the fabric surface, and performing pre-heating, drying and high-temperature setting by a stenter to obtain the finished wool-like knitted fabric. Short fibers are fixed on the base fabric of the knitted fabric with a needling process, so that the thickness and gram weight of the knitted fabric are increased, and the wool-like appearance and hand feeling of the knitted fabric are obtained on the basis of less wool fiber, and the bending length of the knitted fabric after needling finishing is similar to that of the knitted fabric by common milling finishing, which indicates thatthe wool-like fabric can be obtained with the production process.

Description

technical field [0001] The invention relates to the field of textile weaving, in particular to an acupuncture production process for preparing wool-like knitted fabrics from wool-like silk. Background technique [0002] With the use of chemical fibers, various natural fibers can be imitated, such as wool-like, hemp-like, silk-like and cotton-like effects. There are two main technical approaches for chemical fiber wool-like: one is to imitate the morphological structure and performance of wool fiber to develop wool-like fiber; the other is to imitate wool fabric from the appearance, style and performance of the fabric, through spinning, The synergistic effect of spinning, weaving, dyeing and finishing, etc. produces fabrics with the style characteristics and performance of wool fabrics. After years of development and exploration, it is difficult to obtain a satisfactory wool-like effect for chemical fiber fabrics only by simply imitating wool from the fiber structure, and it...
