Single-sided three-dimensional composite structure fabric and manufacturing method

Abstract

This invention relates to a single-sided three-dimensional composite structure fabric and its manufacturing method, including weaving and dissolving steps. The invention uses a Jacquard double-needle bed Raschel warp knitting machine to weave a double-sided fabric, which includes regions forming a wave crest structure and regions without a wave crest structure. The surface layer of the double-sided fabric, mainly woven from soluble yarns, is then dissolved to form a three-dimensional region including a wave crest structure and a bottom layer, and a single-sided region containing only the bottom layer, resulting in a single-sided three-dimensional composite structure fabric. Because the fabric itself is woven on a warp knitting machine in one piece, the overall structure is stable; because the bottom of the wave crest structure is connected to the bottom layer in loops, the wave crest structure is stable, the jacquard pattern is clear, and the fabric is relatively lightweight and thin overall.

Description

Technical Field

[0001] The invention relates to the field of textiles, and in particular to a single-sided three-dimensional composite structure fabric and a manufacturing method thereof. Background Art

[0002] With the development of economy, people's demand for fabrics is getting higher and higher. Three-dimensional fabrics are loved by consumers because of their concave and convex three-dimensional visual impact.

[0003] Double-sided three-dimensional fabrics are relatively thick and have poor air permeability, while existing single-sided fabrics often do not have a three-dimensional effect on the fabric itself. They are single-sided fabrics with a certain three-dimensional effect obtained through post-processing methods such as molding; there is also a single-sided three-dimensional fabric with a relief effect formed by a yarn pressing plate. However, the fabrics obtained by the above processing methods have a low three-dimensional degree and poor three-dimensional sense of touch. Although the three-dimensional jacquard fabrics obtained by the existing process can have a certain concave and convex feeling, the convex part of the fabric is generally a double-layer structure with a thick thickness, and the fabric cannot achieve a light and thin effect. Summary of the invention

[0004] In view of the above problems, the present application provides a single-sided three-dimensional composite structure fabric woven by a jacquard double needle bed Raschel warp knitting machine, which has both a light and thin effect and a three-dimensional effect. The single-sided three-dimensional composite structure fabric has a distinct concave-convex structure, clear jacquard effect, strong three-dimensional effect, and a light and thin fabric surface and a stable structure.

[0005] The first aspect of the present application provides a method for manufacturing a single-sided three-dimensional composite structure fabric, comprising the following steps:

[0006] Weaving: A jacquard double needle bed Raschel warp knitting machine is used to weave the double-sided fabric in one piece; the double-sided fabric comprises a surface layer, a bottom layer and a connecting yarn, the surface layer comprises a first surface layer and a second surface layer, and the bottom layer comprises a first bottom layer and a second bottom layer; the surface layer of the double-sided fabric is mainly woven with soluble yarn, the double-sided fabric comprises a first region and a second region, the first region comprises a first surface layer, a first bottom layer and a connecting yarn; the connecting yarn forms a wave crest structure, the bottom of the wave crest forms a loop on the first bottom layer, and the top of the wave crest forms a weft insertion structure on the first surface layer; the second region comprises a second surface layer and a second bottom layer;

[0007] Dissolving: immersing the double-sided fabric in a dissolving liquid, so that the soluble yarn dissolves, and a single-sided three-dimensional composite structure fabric is obtained.

[0008] Different from the prior art, the above technical scheme provides a method for manufacturing a single-sided three-dimensional composite structure fabric, which uses a double-sided fabric woven integrally by a jacquard double needle bed Raschel warp knitting machine, and the double-sided fabric includes an area where a wave crest structure is formed and an area without a wave crest structure; then the surface layer of the double-sided fabric mainly woven by soluble yarn is dissolved to form a three-dimensional area including a wave crest structure and a bottom layer and a single-sided area with only the bottom layer, and finally a single-sided three-dimensional composite structure fabric is obtained. Since the fabric itself is a warp knitting machine integrally woven fabric, the overall structure is stable; after the surface layer is dissolved, the wave crest structure forms a raised three-dimensional structure; since the bottom of the wave crest structure is connected to the bottom layer in a loop, the wave crest structure is stable and the jacquard pattern is clear. Since there is no surface layer, the fabric is relatively light and thin as a whole.

[0009] In some embodiments, the jacquard double needle bed raschel warp knitting machine comprises a first ground comb, a second ground comb, and a first jacquard comb; the first ground comb, the first jacquard, and the second ground comb are arranged in sequence; the first ground comb and the second ground comb are arranged on the rear needle bed, and the first jacquard comb is arranged on the front needle bed; the first jacquard comb comprises two half-size jacquard comb bars;

[0010] The basic structure of the first jacquard comb is set to 1-0-1-1 / 1-2-1-1 / / , and the jacquard structure does not change during weaving in the first area, or changes to 1-0-1-1 / 2-3-1-1 / / or 1-0-1-1 / 0-1-1-1 / / ; the first jacquard comb weaves a coil with an extension line in the first bottom layer;

[0011] The first ground comb and the second ground comb cooperate with the soluble yarn to weave the surface layer;

[0012] The first ground comb pulls the loop extension line of the first jacquard weaving from the first bottom layer to the first surface layer and incorporates it into the weaving of the first surface layer, so that the connecting yarn forms a weft insertion structure in the first surface layer.

[0013] The setting and weave change of the first jacquard structure can weave the coils and the extension lines of the coils incorporated into the bottom layer; the first ground comb is set in the front position of the first jacquard, and the coil extension lines can be pressed to the surface layer during the weaving process to form a crest; and the top of the crest is incorporated into the weaving of the surface layer by the first ground comb and the second ground comb, forming a weft insertion structure on the surface layer. After the surface layer is dissolved, the crest forms a raised three-dimensional structure.

[0014] In some embodiments, the jacquard structure of the first jacquard comb is changed into a chain weave structure in the second region weaving.

[0015] In some embodiments, the structure of the first ground comb is a warp plain structure, and the threading method is full threading; the basic structure of the first jacquard is a warp plain structure, and the threading method is open threading; the structure of the second ground comb is a plain structure, and the threading method is full threading or open threading.

[0016] In some embodiments, the jacquard double needle bed Raschel warp knitting machine further includes a third ground comb, which is arranged on the front needle bed, has a plain warp or satin warp structure, and has a full threading method to weave the bottom layer.

[0018] In some embodiments, the jacquard double needle bed raschel warp knitting machine further includes a third ground comb and a fourth ground comb, the third ground comb and the fourth ground comb are arranged on the front needle bed, the organization is a mesh organization, the threading method is full threading or empty threading, and the bottom layer is woven. In this way, the woven single-sided three-dimensional composite structure fabric will have regular meshes.

[0019] In some embodiments, the jacquard double needle bed raschel warp knitting machine further includes a third ground comb and a second jacquard comb, the second jacquard comb includes two half-size jacquard comb bars, the third ground comb and the second jacquard comb are arranged on the front needle bed, the third ground comb has a chain weave structure, and the threading method is full threading; the second jacquard comb has a plain weave structure, and the threading method is empty threading. The single-sided three-dimensional composite structure fabric woven in this way will have regular mesh or irregular mesh. The designer can design the mesh size and distance according to needs.

[0020] In some embodiments, the soluble yarn includes water-soluble yarn and alkali-soluble yarn. The water-soluble yarn can be dissolved in aqueous solution, while the alkali-soluble yarn can be dissolved in weak alkaline solution; the above solutions do not damage the woven yarn and fabric and affect the underlying structure.

[0024] Different from the prior art, the above technical solution provides a single-sided three-dimensional composite structure fabric, which is obtained by reprocessing the double-sided fabric woven by a warp knitting machine. Since the three-dimensional area yarn is the connecting yarn between the surface layer and the bottom layer of the warp knitting double-sided fabric, after the surface layer is dissolved, the connecting yarn forms a three-dimensional area with a crest structure. Because there is no surface layer, the fabric is lighter and thinner overall. And the three-dimensional area yarns are all connected to the bottom surface in a loop, and the structure is stable.
