Detailed Description
To further illustrate the technical means and effects of the present invention, the following detailed description is given with reference to the embodiments of the present invention and the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of a method for making a triple layer wire according to the present invention, comprising:
s100, alternately weaving by adopting at least two weaving methods to form a paper layer;
wherein the at least two weaves comprise at least a plain weave, a satin weave, and a twill weave.
The plain weave fabric is characterized in that warps and wefts of a plain weave are interwoven in an upper-lower rule. That is, every other yarn of the warp and weft yarns is interlaced once, so that the interlacing point is the largest, the yarn buckling point is the largest, and the fabric is firm, wear-resistant, stiff and flat, but the elasticity is smaller, the gloss is general, the density of a plain weave fabric is not too high, the fabric is lighter and thinner, the wear resistance is better, and the air permeability is better.
The twill fabric has a complete structure that at least three warps and three wefts are interwoven, and each warp and weft only has one weft warp structure point. The fabric surface is formed with oblique lines by continuous weave points. Twill weave is the appearance effect of the twill exhibited by the surface of a fabric made up of warp or weft floats. The weaving times of the warps and the wefts of the twill fabric are less than those of plain weave, so that the gaps among the warps and the wefts are small, the yarns can be arranged densely, and the fabric is dense and thick. The twill is softer in hand feeling and better in elasticity than plain weave fabrics. However, the twill fabrics have longer floating length, so the twill fabrics have inferior wear resistance and fastness to plain fabrics under the conditions of same thickness and density of warp and weft yarns. The cloth surface has obvious oblique lines, hand feeling, luster and better elasticity.
The satin weave means that the warps (or wefts) are longer in floating and less in interweaving points, form oblique lines but are not continuous, and are regularly and uniformly spaced, and the fabric structure is called satin weave. The satin fabric has longer float length line and the worst fastness, but has soft texture, smooth silk surface and good luster, is noble and gorgeous, and is widely applied to the fabric. The ground weave in the pattern weave such as brocade satin, satin and the like is satin weave. Satin weave structure satin generally refers to the side of the fabric that reflects more warp-wise raw materials: if satin is used in the warp direction, the surface with good gloss is called a satin surface at ordinary times, the satin is different from plain weave and twill in that the upper thread jumper is longer, the twill included angle is smaller, the gloss is stronger, the satin is smoother and more attractive, and the defect is that the yarns are easy to cut and are not soft enough although the yarns are smooth.
S100, the step of forming the paper layer by alternately weaving at least two weaving methods specifically comprises the following steps:
s120, alternately weaving by adopting a plain weaving method and a satin weaving method to form a paper layer;
two surface layer wefts are arranged in each group of minimum circulating structure units, and one weft is in a plain weave method and the other is in a satin weave method through the change of heald frames.
In addition, in other embodiments of the method for manufacturing a three-layer wire, the paper layer can be formed by alternately weaving a plain weave method and a twill weave method.
Specifically, in step S120, the paper layer is alternately woven by using an 1/1 plain weave weaving method and a 2/3 satin weave method.
