Abstract

The invention discloses a woven fabric with perforated lines and a processing technology, and relates to the field of woven fabric processing. The tightness of the first tissue is tighter, and the first tissue is squeezed in the direction of the second tissue, forming a hole-like pattern in the first tissue. When the tightness of the first tissue is tighter than that of the second tissue, the first tissue is closer. The tension between the two tissues is large, so that the first tissue will be squeezed and moved in the direction of the second tissue, so that during the extrusion of the first tissue to the outside, a hole will be formed in the first tissue or between two adjacent first tissues. The formation of grains and hole-like grains makes the air permeability of the ready-made woven fabrics significantly improved compared with the plain weave fabrics currently on the market.

Description

A kind of woven fabric with perforated pattern and processing technology

technical field

The invention relates to the field of woven fabric processing, in particular to a woven fabric with perforated lines and a processing technology.

Background technique

Woven fabrics are composed of looms in the form of shuttles, and the yarns are interlaced in the warp and weft directions. Such fabrics are firm, stiff and not easily deformed due to the interlacing of warp and weft. According to the composition, it includes cotton fabrics, silk fabrics, wool fabrics, hemp fabrics, chemical fiber fabrics and their blended and interwoven fabrics. The use of woven fabrics in clothing is a world leader in both variety and production quantity. Widely used in all kinds of high-end clothing, woven clothing has great differences in processing flow and technological means due to the differences in style, craftsmanship, style and other factors.

However, most of the traditional structures of current woven fabrics are plain weave (the warp and weft yarns of the entire fabric are closely interwoven up and down), which makes the entire fabric less breathable.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the above-mentioned deficiencies, and to provide a woven fabric with a perforated pattern and a processing technology.

[A kind of woven fabric with perforated texture disclosed according to the present invention]

A woven fabric with a perforated pattern, comprising a fabric body, the fabric body comprising a first weave and a second weave connected, the tightness of the first weave is tighter than that of the second weave, and the first weave is tighter than the second weave. The weave is squeezed in the direction of the second weave, forming a hole-like pattern in the first weave, that is to say, the interlacing points of the warp and weft yarns in the first weave are denser than the interlacing points of the warp and weft yarns in the second weave, and the unit length is There are more interwoven points in the inner part. When the tightness of the first tissue is tighter than that of the second tissue, the tension between the first tissue is greater, so that the first tissue will be squeezed and moved in the direction of the second tissue. In this way, during the extrusion of the first tissue to the outside, a hole-like pattern will be formed in the first tissue or between two adjacent first tissues.

Preferably, both the first weave and the second weave are formed by interlacing warp yarns and weft yarns, and the weave density of the first weave is greater than that of the second weave, and the number of weave points per unit length is greater.

Preferably, both the warp and the weft are polyester or monofilament, but it is not limited to these two types of yarns, and other functional yarns can also be used. If monofilament is used, it has a certain degree of support and is not easily deformed, so that the hole-like texture is formed. Better support and better breathability.

Preferably, the fabric body includes a single braided layer, the single braided layer includes a first tissue and a second tissue connected to each other, the entire fabric body can be a single-layer structure with only a single braided layer, and the single-layer structure has better air permeability .

Preferably, the fabric body includes an upper braided layer, an intermediate layer and a lower braided layer, the intermediate layer is used for connection between the upper braided layer and the lower braided layer, and at least one braided layer of the upper braided layer and the lower braided layer includes Connect the first tissue and the second tissue. The entire fabric body can be a multi-layer structure, specifically a three-layer structure. While increasing the thickness of the entire fabric body, a hole-like pattern is formed on the upper knitting layer or the lower knitting layer or the upper and lower knitting layers to improve the overall woven fabric. of breathability.

Preferably, the intermediate layer is made of monofilament woven, and the monofilament is used as a connection point for the connection between the upper braided layer and the lower braided layer. There is a certain support between them, so as to avoid the overlapping of the hole-like patterns between the upper woven layer and the lower woven layer, and further improve the air permeability of the multi-layered woven fabric.

Preferably, the perforated pattern includes a plurality of air holes distributed at intervals. Is the perforated pattern mainly composed of a plurality of ventilation holes? Since the first tissue is squeezed in the direction of the second tissue, a plurality of ventilation holes with a certain aperture will be formed in the first tissue or between two adjacent first tissues. hole.

[According to the processing technology of a woven fabric with a perforated pattern also disclosed in the present invention]

The process includes:

S1: According to the relevant parameters of the fabric, use the software to make EP format files and input them into the shuttle loom, preload the warp yarns on the weaving warp head of the shuttle loom, and put the corresponding weft yarns into the weft storage device of the shuttle loom middle;

S2: Start the shuttle loom for weaving, and the shuttle loom automatically interweaves the weft yarns with the warp yarns in sequence. Specifically: each weft yarn is interwoven with the warp yarns to form an interweaving row. It is the floating point, the weft yarn on the bottom surface is called the settling point, and the continuous floating point or settling point constitutes the floating weave. The first weave, the longer one is called the second weave, and finally forms the fabric body;

S3: cutting the formed fabric body through a shuttle loom to form a required number of fabric parts; compounding the fabric parts and the base fabric to form a fabric fabric;

S4: Cut out the fabric, and then laser process it into the desired woven fabric.

Preferably, the shuttle loom includes 6-10 weft feeders.

Preferably, the woven fabric is any one of a shoe upper, a garment surface, and a packaging bag surface.

By adopting the above-mentioned technical scheme, the beneficial effects of the present invention are:

1. When the tightness of the first tissue is tighter than the tightness of the second tissue, the tension between the first tissue is greater, so that the first tissue will be squeezed and moved in the direction of the second tissue, so that the first tissue will move in the direction of the second tissue. During the extrusion process on the outside, a hole-like pattern will be formed in the first weave or between the two adjacent first weave, and the formation of the hole-like pattern makes the ready-made woven fabrics similar to the more plain weave fabrics currently on the market. The air permeability is significantly improved.

2. The upper is formed by interweaving the warp and weft yarns. During the interweaving process, the interweaving rows are interwoven to form floating weaves of different lengths, and then the first weave and the second weave are formed on the upper, and finally the first weave and the second weave are formed on the upper. The interaction of the two tissues forms a hole-like pattern, which improves the breathability of the entire upper.
