Embodiment 1

[0033] (1) Selection of raw materials:

[0034] Choose polyester yarn and cotton yarn for weaving. Among them, the connecting wire of the interval layer is woven with 75D polyester yarn, the small formation coil is woven with 30D polyester yarn, and the fabric surface coil is woven with 40S cotton yarn.

[0035] (2) Weaving and yarn arrangement process:

[0036] Such as Figure 4 , as shown in 5 and 6, the weaving principle is mainly that the stratum coil does not take off the loop after it is looped, and forms the same row with the surface coil synchronously. Weaving is carried out on a modified weft knitting double-sided circular weft machine, and a six-way loop forming system is used to weave a coil course; according to Figure 5 The knitting needles are arranged in a triangle for movement. The 1st and 2nd knitting tucks are used as connecting yarns, and the 3rd and 4th knitting needles are all knitted to form a loop. The 3rd knitting formation loop does not take off th...

Embodiment 2

[0040] (1) Selection of raw materials

[0041] Choose polyester yarn, cotton yarn, spandex for weaving. Among them, the connecting wire is woven with 75D polyester yarn, the small coil is woven with 30D polyester yarn, and the fabric surface coil is woven with 40S cotton yarn and 20D spandex.

[0042] (2) Weaving and yarn arrangement process

[0043] Such as Figure 4 , as shown in 5 and 6, the weaving principle is mainly that the stratum coil does not take off the loop after it is looped, and forms the same row with the surface coil synchronously. Weaving is carried out on the modified weft knitting double-sided circular weft machine, and the six-way knitting system weaves a coil course, according to Figure 5 The knitting needles are arranged in a triangle for movement. The 1st and 2nd knitting tucks are used as connecting yarns, and the 3rd and 4th knitting needles are all knitted to form a loop. The 3rd knitting formation loop does not take off the loop. When the 4th k...

Embodiment 3

[0047] (1) Selection of raw materials

[0048]Choose polyester yarn, cotton yarn, spandex for weaving. Among them, the connecting wire is woven with 75D polyester yarn, the small coil is woven with 30D polyester yarn, and the fabric surface coil is woven with 40S cotton yarn and 20D spandex.

[0049] (2) Weaving and yarn arrangement process

[0050] Such as Figure 4 , as shown in 5 and 6, the weaving principle is mainly that the stratum coil does not take off the loop after it is looped, and forms the same row with the surface coil synchronously. Weaving is carried out on a modified weft knitting double-sided circular weft machine, and a six-way loop forming system is used to weave a coil course; according to Figure 5 The knitting needles are arranged in a triangle for movement. The 1st and 2nd knitting tucks are used as connecting yarns, and the 3rd and 4th knitting needles are all knitted to form a loop. The 3rd knitting formation loop does not take off the loop. When ...

Abstract

The invention discloses a weft-knitted fabric with a multilayer structure and a weaving method thereof. The multilayer structure at least includes a ground layer, a spacer layer and a surface layer, that is, a four-layer structure of surface layer-ground layer-spacer layer-surface layer; The method is as follows: adjust the angle of the dial triangle and the needle cylinder triangle on the double-sided knitting circular knitting machine, change the trajectory of the triangle, so that the knitting needles do not move to the degree of stripping; the knitting fabric stratum is woven into circles on the knitting needles with small loops , tuck or float, weave on either side or both sides of the fabric; the spacer layer of the woven fabric is connected to the ground layer by tuck or loop, and is not directly hung on the surface layer coil to avoid damage to the fabric surface. influences. The surface layer of the woven fabric is woven by knitting all the knitting needles into loops or by selecting needles to form loops, tucks, and floating threads. The stitches that form the same course can give the fabric surface a textured effect.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a weft-knitted fabric with a multi-layer structure and a weaving method thereof. Background technique [0002] The weft-knitted sandwich fabric is woven on a weft-knitting circular weft machine. It consists of an upper layer, a lower layer, and an intermediate connection layer connecting the upper and lower layers. Generally, the upper and lower layers are made of cotton yarn and other yarns with good skin-friendly properties. The layer is generally made of polyester and other chemical fibers, which have a certain supporting effect. The fabric has a certain elasticity and thickness, can store a certain amount of air, has good mechanical cushioning, excellent elasticity, and good warmth retention, and is widely used in sportswear. [0003] At present, although the weft-knitted sandwich structure fabric is widely used, it still has certain defects. The middle connect...
