detailed description

In order to make people understand the features, content and advantages of the utility model and the effects it can achieve, the embodiments of the utility model will be described in detail below with reference to the accompanying drawings. Among them, the drawings used are only used for illustration and auxiliary description, and may not be completely consistent with the actual structure of the utility model after implementation. The scope of rights of the utility model when it is actually implemented.

By describing in more detail with reference to the embodiments and accompanying drawings, the advantages, features and technical methods achieved by the utility model can be understood more easily. In addition, the utility model can also be realized in different forms. Therefore, the utility model It is not limited to the embodiments described below. On the contrary, for those skilled in the art, the provided embodiments can convey the scope of the present utility model more thoroughly, comprehensively and completely. In addition, the scope of the present utility model is Defined by the content described in the claims.

Fig. 1 is a schematic diagram of the breathable circular braid of the present invention. It can be seen from FIG. 1 that the breathable circular knitted fabric 100 is woven by a circular knitting machine according to the structure pattern, wherein the structure pattern includes fabric density and pore planning, and the circular knitting machine has a needle transfer device and a plurality of needle selectors. The tissue pattern is edited and set by the user according to actual needs. In addition, the tissue pattern may also include a jacquard pattern to increase the aesthetics of the breathable circular knitted fabric 100 .

The breathable circular knitted fabric 100 is composed of a plurality of braided parts 10 and a plurality of hole parts 20 . A plurality of knitting parts 10 use a plurality of needle selectors correspondingly arranged in different weaving methods such as loop cams, tuck cams, and float cams according to the fabric density to twist a plurality of yarns 5 into a plurality of loops in sequence 15.

At the same time, the transfer device is used to transfer the upper and lower adjacent yarn rings 15 according to the pore planning to perform loop transfer knitting between the left and right or the upper and lower wefts, or perform transfer knitting between the front and rear wefts, and then multiple yarns 5 are staggered through hook yarns. A plurality of voids 20 are formed by weaving.

Pore planning can define the position and size of a single pore and the arrangement of multiple pores according to the tissue composition designed by the user. The needle transfer device can turn over multiple yarn loops 15 of the upper (lower) needle bed to the lower (upper) needle bed according to the pore planning to increase the edge strength of the multiple pore parts 20, thereby knitting a pattern with a concave-convex feeling, The air-permeable circular braid 100 with a three-dimensional effect and a mesh-like pore structure.

The yarn materials of the plurality of yarns 5 can be selected from natural fibers, natural polymer fibers or synthetic polymer fibers, wherein the natural fibers can include animal fibers such as wool, camel hair, rabbit hair, silk, or cotton, hemp, agar hemp, etc. Vegetable fiber. However, there are many types of natural polymer fibers and synthetic polymer fibers, so details will not be repeated here.

Furthermore, yarn types of different processes can also be selected according to different functional requirements. For example, monofilament fiber yarn can be used to increase the strength and stiffness of the fabric; elastic fiber yarn can be used to give the fabric proper elasticity and shrinkage. Sex; the choice of twisted yarn can also give flexibility in yarn selection.

It is further explained that the type of yarn can be a homogeneous heat-melt yarn with double melting points, using different melting points of the inner and outer layers to meet individual functional requirements. Among them, the outer covering layer with a lower melting point range (130° C. to 220° C.) can not only increase the weaving processability of the yarn, but also increase the dyeing and finishing color fastness of the yarn. The inner layer structure with a higher melting point (150°C to 260°C) can provide the straightness of the fabric to increase the structure of the overall fabric.

Yarn types using the same material can have relatively similar physical properties, so as to reduce the complexity of process parameter control in the weaving process. Furthermore, yarns of the same material can reduce the difficulty of recycling sapwood, so as to increase the proportion of recycling and reduce related costs, and can further achieve the purpose of environmental protection and energy saving.
