Problems solved by technology

[0003] In weft knitting, the most commonly used weaving element is the needle cylinder. The conventional needle cylinder is composed of an upper needle cylinder and a lower needle cylinder. The gap between the spacer and the spacer is the yarn groove, and the yarn passes through different yarn grooves to form a weft knitted fabric. Although this structure is relatively fast, due to the limitations of the needle cylinder itself, the yarn The thickness of the thread and the pattern of the weave can only be circulated along the weft direction. Although some people in the industry have developed irregular needle cylinder micro-units such as those provided by patent 2013207319358 to achieve the adjustment of different needle level widths, but the large circular knitting machine with this structure There are still certain defects in the needle cylinder. In the weaving process, the upper needle cylinder adopts a conventional structure, and the lower needle cylinder adopts the irregular needle cylinder micro-unit as described in this patent. During the weaving process, the pattern, yarn count The change of thickness can only be realized by the lower needle cylinder, which is very prone to wrong stitches, and this irregular structure is easy to cause the yarn to be loose and tight at times, and in serious cases, there may even be thread jumping, which is not conducive to production control
[0004] At the same time, the thickness and style of the front and back of the fabric produced by the traditional ordinary double-sided large circular machine are not much different; in the current clothing market, thick needle clothing is very popular, but most of them are single-sided thick needle, double-sided thick Knitted fabrics are generally thick and not suitable for making spring and autumn clothing

Embodiment 1

[0030] In this embodiment, the double-sided differential knitted fabric is combined with figure 1 , consisting of a front 41 and a back 42, the back 41 is woven with a low needle level, and the front is woven with a high needle level or mixed with a low needle level and a high needle level.

[0031] The weaving process of the above-mentioned double-sided differential knitted fabric is as follows:

[0032] The yarn or fiber is carried out on the double-sided differential needle cylinder, which is composed of the upper needle cylinder 1 and the lower needle cylinder 2, and the upper needle cylinder 1 and the lower needle cylinder 2 are respectively provided with spacers 3, The spacing between adjacent spacers 3 is in a changing state, and the spacing is set at a dense interval; combined with Figure 5 , the top surface of the upper needle cylinder 1 has a slope structure; the yarn or fiber passes through the upper needle cylinder 1 and the lower needle cylinder 2 in sequence, a...

Embodiment 2

[0035] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that: on the upper needle cylinder 1, the distance between adjacent spacers gradually increases first, then gradually decreases, then gradually increases, and then circulates successively to form a dense interval structure; on the lower needle cylinder 2, the spacing between adjacent spacers is the same, and the spacing is not less than the minimum spacing between adjacent spacers on the upper needle cylinder 1; figure 2 The structure shown includes a dense region 41, a transition region 42 and a fluffy region 43; wherein, the dense region 41 is woven with a low needle grade, and the fluffy region 42 is woven with a high needle grade.

Embodiment 3

[0037] In this embodiment, the double-sided differential knitted fabric is combined with figure 2 , consisting of a front 41 and a back 42, the back 41 is woven with a low needle level, and the front is woven with a high needle level or mixed with a low needle level and a high needle level. Specifically in this embodiment, combined with image 3 , the front side 41 includes a dense area 411, a fluffy area 413 and a transition area 412 arranged alternately, the transition area 412 is arranged between the dense area 411 and the fluffy area 413, and the density of the transition area 412 is between the dense area 411 and the fluffy area 413 , and connect the dense area 411 and the fluffy area 413 together in a gradual manner, from figure 2 It can also be seen from the cross-sectional view that the fluffy region 413 is higher than the dense region 411.

[0038] The weaving process of the above-mentioned double-sided differential knitted fabric is as follows: the yarn or fiber ...

Abstract

The invention relates to a double-faced differential knitted fabric and a weaving process therefor, and belongs to the technical field of knitting. The double-faced differential knitted fabric is composed of a front surface and a back surface, wherein the back surface is formed by low needle level weaving; and the front surface is formed by high needle level weaving or low and high needle level hybrid weaving. The process is applied to the operations of weft knitting weaving and the like, so that the operations are stable, fabrics with different densities can be weaved, and a raised line effect with concave-convex change can be achieved.

Description

technical field [0001] The invention relates to a double-sided differential knitted fabric and its weaving process, belonging to the technical field of weaving. Background technique [0002] Knitted fabrics are divided into weft knitting and warp knitting. The vertical and horizontal extensibility of weft knitting fabrics is better than warp knitting, and the production process and production equipment of weft knitting are simpler than warp knitting. Weft knitting can directly produce finished clothing, while warp knitting only It can produce fabrics, so weft knitting applications are more common. [0003] In weft knitting, the most commonly used weaving element is the needle cylinder. The conventional needle cylinder is composed of an upper needle cylinder and a lower needle cylinder. The gap between the spacer and the spacer is the yarn groove, and the yarn passes through different yarn grooves to form a weft knitted fabric. Although this structure is relatively fast, due...
