Problems solved by technology

However, because the fabric is a weft-knitted structure, the coils are easy to fall apart, and may break during wearing, so it is not suitable for outdoor sports fabrics that require high strength.
In addition, the breathability of the fabric needs to be further improved
[0004] Another example is disclosed in the patent document CN205556966U a kind of cotton imitation knitting fabric of polyester silk, and this fabric is weft-knitted plain weave, and this plain weave is interwoven by the first imitation cotton composite silk and the second imitation cotton composite silk, and its interweaving structure is : Coils are formed from threads along the horizontal direction, and the coils are put on each other; the first cotton-like composite yarn and the second cotton-like composite yarn are both cotton-like different shrinkage composite yarns, and the resulting fabric feels fluffy, and has good water absorption and quick-drying effect , the cloth surface has the effect of short-fiber cotton yarn, but also because it is a weft-knitted plain weave, there is also the problem that the coils are easy to detach; and the composite yarn used is obtained from modified polyester POY and modified polyester FDY through mixed fiber processing, The process is cumbersome and the cost is high
[0005] Another example is the patent document CN103789920A which discloses a production method of a super-imitation cotton warp-knitted fabric with a moisture-conducting function. The super-imitation cotton polyester fiber filament and the "Y" shaped cross-section fine-denier polyester long yarn processed by elasticizing are used. Yarn is obtained by weaving double-combed warp and oblique weaves. It not only has the excellent hygroscopicity, softness and warmth retention of cotton fabrics, but also has good mechanical properties and moisture conductivity of polyester fabrics. , but the surface of the fabric is relatively tight, and the air permeability is not good; in addition, the super imitation cotton polyester fiber filament is compounded by polyester FDY and ultrafine polyester POY through false twist deformation, the process is cumbersome, and the cost is also increased

Embodiment 1

[0093] On the HKS4 tricot warp knitting machine (machine number E28, machine width 136 inches), select 75D-144f-cotton-feeling polyester filament (manufactured by Toray Synthetic Fiber (Nantong) Co., Ltd., with a fusion degree of 45%. The length of the wearing part is 1.5mm), using the front and rear two combs to change the warp and satin weave to weave, and the front and rear two combs have accumulated 11 stitches to make the gray cloth, and then through scouring, dyeing, fluffing and other processing to obtain the gray cloth of the present invention. Cotton-feeling knitted fabrics, see Table 1 for details.

[0094] Among them, scouring: caustic soda 2g / L, scouring agent 2g / L, 90℃×20min, liquor ratio 1:20; dyeing: 130℃×30min, reduction cleaning: 80℃×20min.

Embodiment 2

[0096] Select 75D-144f-cotton-feeling polyester filament (manufactured by Toray Synthetic Fiber (Nantong) Co., Ltd., the degree of fusion is 21%, and the length of the fusion part is 0.42mm), and use two combs at the front and back to weave with changing warp and satin weave , the accumulative transverse movement of the front and back two combs is 7 needles to obtain a gray cloth, and the rest are the same as in Example 1 to obtain the cotton-feeling knitted fabric of the present invention, see Table 1 for details.

Embodiment 3

[0098] Select 75D-144f-cotton-feeling polyester filament (manufactured by Toray Synthetic Fiber (Nantong) Co., Ltd., the degree of fusion is 45%, and the length of the fusion portion is 1.5mm) as raw material, and the rest are the same as in Example 2 to obtain the present invention The cotton-feeling knitted fabric, see Table 1 for details.

Abstract

The invention discloses cotton-feeling knitted fabric. The fabric is a warp knitted fabric formed by the coil of a cotton-feeling polyester filament yarn, the height of the coil is 0.10-1.50 mm, the width of the coil is 0.10-2.00 mm, and the variation coefficients of the height and the width are both 30%-60%, wherein the cotton-feeling polyester filament yarn is provided with a fusion part A and anon-fusion part B. The knitted fabric provided by the invention has extremely strong appearance and hand feeling of cotton, and also has good air permeability.

Description

technical field [0001] The invention relates to a cotton-feeling knitted fabric, in particular to a warp-knitted fabric formed of cotton-feeling polyester filaments. Background technique [0002] Generally speaking, compared with chemical fibers, cotton products have good water absorption and soft hand feeling, but in the process of wearing, there are problems such as poor quick-drying, low strength, and poor dimensional stability. Therefore, using chemical fibers instead of cotton fibers to produce cotton products with Cotton-like fabrics that have the advantages and can solve the shortcomings of cotton are very necessary. [0003] At present, research on imitation cotton fabrics has also become a hot spot. For example, the patent document CN105734805A discloses a cotton-like knitted fabric and its production method. The weft-knitted plain cloth is formed by weaving polyester filaments with alternating thick and fine details on a circular knitting machine, and the pore are...
