Embodiment 1

[0034] (1) Selection of raw materials:

[0035] 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.

[0036] (2) Weaving and yarn arrangement process:

[0037] 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

[0041] (1) Selection of raw materials

[0042] 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.

[0043] (2) Weaving and yarn arrangement process

[0044] 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...

[0048] (1) Selection of raw materials

[0049]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.

[0050] (2) Weaving and yarn arrangement process

[0051] 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.

Abstract

The invention discloses a weft-knitted fabric with multilayer structure and a knitting method thereof; the multilayer structure at least comprises a ground layer, a spacer layer and face layers, namely a face-ground-spacer-face four-layer structure. The knitting method includes: adjusting an angle between a dial cam and a cylinder cam on a double-side circular knitting machine to change a cam track, so that a knitting needle does not move to a loop cast-off degree; knitting a fabric ground layer in a manner that small loops are woven into loops, tucks or floating threads via a knitting needle,wherein weaving is carried out on any one surface or two surfaces of the fabric; knitting a fabric spacer layer in a manner of connecting the ground layer in a tucking or looping mode, with hanging directly on the face layer loops not performed, so that the influence on the cloth surface of the fabric is avoided; and knitting fabric face layers in a manner that all knitting needles are subjectedto knitting to obtain loops or selected needles are subjected to knitting to obtain loops, tucks and floating threads, wherein after the loops of the face layers are knitted into loops, the loops andloops sleeving needle shanks are cast off together, the loops of the same transverse row are formed, so that the fabric face layers are textured.

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...
