Description

Improved warp-knitted fabric not easy to curl and capable of being cut at will

The technical field is as follows:

the utility model belongs to in the warp knitting surface fabric field, concretely relates to be a warp knitting surface fabric that modified difficult turn-up can be cut out wantonly.

Background art:

the existing warp-knitted fabric has higher and higher functional requirements on clothes along with the living health requirements of people, pursues lightness, thinness and no trace, and the random cutting can be realized in the production process, which puts higher requirements on the weaving method of the fabric, in order to meet the requirement, the invention patent with the Chinese patent number of 201910413138.7 discloses a cloth, the adopted surface weaving layer adopts a weaving method of a warp pile structure and a ground weaving layer heavy warp flat structure, so that the cloth can obtain better overall elasticity, but because two different weaving methods are mixed, the tension imbalance naturally exists to cause the cloth to be self-rolled, so that the product made of the cloth is easy to have the edge curling phenomenon, the improved scheme is that a third yarn is added to form a transverse elastic structure, but the supporting force in the vertical direction is still insufficient, the edge curling phenomenon still exists, and the product defect is obvious.

The invention content is as follows:

the utility model aims to overcome the defects of the prior art, and provides an improved warp-knitted fabric which is not easy to curl and can be cut at will.

The utility model provides a technical scheme that its technical problem adopted is: the improved warp-knitted fabric which is not easy to curl and can be cut at will is characterized by comprising a body formed by interweaving four strands of yarns through a warp-knitting process, wherein the four strands of yarns are respectively a first yarn, a second yarn, a third yarn and a fourth yarn; the first yarn is of a closed warp-pile weave structure, and the yarn padding number is 1-0/2-3//; the second yarn is in a closed heavy warp flat structure, and the yarn laying number is 2-0/1-3//; the third yarn is a weft insertion weave structure, and the yarn laying number is 0-0/1-1//; the fourth yarn is weft insertion structure and the yarn laying number is 0-0/2-2//.

The third yarn and the fourth yarn have the same diameter.

The first yarn is made of chinlon yarn, and the second yarn, the third yarn and the fourth yarn are made of spandex yarn.

The third yarns and the fourth yarns are periodically inserted into the closed double warp flat structure formed by the second yarns, the weft insertion structure formed by the third yarns is a structure with a stitch length of 1, and the weft insertion structure formed by the fourth yarns is a structure with a stitch length of 2.

The third yarn and the fourth yarn are of partial weft insertion weave structures.

As a modified example, the third yarn and the fourth yarn are of a full weft insertion weave structure.

The utility model discloses a warp knitting surface fabric that modified difficult turn-up can be cut out wantonly adopts on the surface weaves the layer and weaves the current basis on layer with ground, increases the weft insertion organizational structure that third, fourth yarn that have balanced structure made into, and third, fourth yarn adopt horizontal line and vertical alternately to produce the structure of elasticity, can effectual control cloth first, the self-winding problem that the weave that adopts between the second yarn brought, can effectively improve product quality's advantage.

Description of the drawings:

fig. 1 is a schematic diagram of the cloth structure of the present invention.

Fig. 2 is a schematic diagram of the partially exploded structure of the present invention.

Fig. 3 is a schematic view of the second yarn structure of the present invention.

Fig. 4 is a schematic view of the whole exploded structure of the present invention.

The specific implementation mode is as follows:

as shown in fig. 1 and 4, an improved warp-knitted fabric which is not easy to curl and can be cut at will is characterized in that the fabric comprises a body formed by interweaving four strands of yarns through a warp knitting process, wherein the four strands of yarns are respectively a first yarn, a second yarn, a third yarn and a fourth yarn; the first yarn is of a closed warp-pile weave structure, and the yarn padding number is 1-0/2-3//; the second yarn is in a closed heavy warp flat structure, and the yarn laying number is 2-0/1-3//; the third yarn is a weft insertion weave structure, and the yarn laying number is 0-0/1-1//; the fourth yarn is weft insertion structure and the yarn laying number is 0-0/2-2//. The fabric body obtained by the four groups of yarns has transverse elasticity and vertical elasticity, and meanwhile, the yarns are stressed in a balanced manner, so that the self-rolling phenomenon cannot occur, and the fabric body also has the excellent performance of basically cutting at will without stretch cracking.

As shown in fig. 3, each first yarn 11 is interlaced with another yarn by one stitch so that the warp knitting structure formed by knitting the first yarn 11 is a warp pile structure, the extending lines of the warp pile structure span two needle pitches, the warp pile structure is a closed loop structure, the loops of the loop structure are closed loops, that is, the extending lines at the base of the loops cross each other. The closed warp-pile texture is used as the facial texture.

As shown in fig. 3, each second yarn 21 is simultaneously laid on two adjacent needles and knitted into a loop, so that the second yarn 21 is knitted into a double warp flat stitch, which is a closed heavy warp flat stitch, and the loops of the double warp flat stitch are closed loops, that is, the extension lines of the base of the loops intersect with each other. The closed heavy meridian-level tissue is used as the ground tissue.

The third yarn and the fourth yarn have the same diameter. The third yarn and the fourth yarn with the same wire diameter can ensure that the woven weft insertion layer has the same transverse elasticity and vertical tension, and ensure that the cloth cannot be curled.

The first yarn is made of chinlon yarn, and the second yarn, the third yarn and the fourth yarn are made of spandex yarn. Of course, yarns made of other materials may be used, and are not limited to the embodiments of the present invention.

As shown in fig. 2, the third yarn and the fourth yarn are inserted into the closed double warp flat stitch structure formed by the second yarn periodically, the weft insertion stitch structure formed by the third yarn is a structure with a stitch length of 1, and the weft insertion stitch structure formed by the fourth yarn is a structure with a stitch length of 2.

As a modified embodiment, the third yarn and the fourth yarn are in a partial weft insertion weave structure. And part of the weft insertion weave structures can be woven into the required weft insertion structures on the paths close to the cutting lines according to the actual cutting requirements in the production process. The technical effect of the edge curling resistance of the cloth is improved at the edge of the cutting line.

The above disclosure is only for the specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
