Description

Technical Field

[0001] The invention relates to the technical field of knitted fabric textiles, in particular to an anti-pilling knitted fabric. Background Art

[0002] Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. The difference between knitted fabrics and woven fabrics is that the yarns are in different shapes in the fabric.

[0003] In order to prevent pilling, existing knitted fabrics usually use high-fiber and new-material fibers to make monofilament fabrics, and then improve the weaving method to achieve the purpose of anti-pilling.

[0004] However, in actual use, the pilling of knitted fabrics depends on the thickness and friction of the fabrics. For thick fabrics, a plush layer is usually required to keep them warm and soft. As the fabrics are used and rubbed, pilling occurs. The improvement of fabrics and textile methods using traditional techniques can only be applied to thin fabrics. For fabrics that require warmth and softness, the improved fibers cannot achieve the purpose of keeping warm, and therefore cannot meet the anti-pilling requirements for thick knitted fabrics. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-pilling knitted fabric to solve the anti-pilling problem of thick knitted fabrics.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0022] Preferably, after the middle layer fabric is woven, the fabric is placed under a laminator and laminated for 20-30 minutes at a pressure of 500-750N until the thickness of the middle layer fabric is less than the sum of the thicknesses of the outer layer fabric and the inner layer fabric.

[0023] Preferably, the sewing density per unit area of ​​the connecting layer is 2 stitches per square centimeter.

[0024] Preferably, the cables of the connecting layer penetrate the middle fabric layer, the outer fabric layer and the inner fabric layer, and the thickness of the double threads sewn in the connecting layer is less than the thickness of the plush layer.
