Problems solved by technology

[0002] As we all know, as an ideal textile in summer, hemp fiber fabric has the advantages of being comfortable, non-sticky, dry and breathable, but because the chemical composition of hemp is basically the same as that of cotton fiber, it is also easy to deform and wrinkle, and has poor shape retention. In addition, there are the following problems : Easy to fade when washing, should not be exposed to the sun, and should not be hung to dry, etc.
For example, the linen-like plain weave fabrics made of cationic polyester filament and air-textured ordinary polyester filament are processed through strong twisting, pre-shrinking, shaping, dyeing and finishing, but because the air-textured yarn has more loops , will reduce the dryness of the cloth surface, not suitable for spring and summer use
[0004] In addition, in order to obtain a cool feeling, the patent document CN200810146173.9 discloses a fabric formed by using thick fiber false-twisted yarn. Although the production cost is relatively low and the cool feeling is excellent, the dynamic friction coefficient of the fabric reaches 2.0, and the surface of the fabric will It is very uneven, not suitable for wearing next to the skin, and its use is greatly restricted; and it does not have the unique style of natural hemp fiber due to unevenness.

Embodiment 1

[0041] Using 95D-36f-polyester fused with DTY and 75D-36f-bright polyester FDY for weaving, the organization is ordinary jersey, and knitted gray fabric is woven on a 28G single-jersey machine, and the fusion area of ​​the fusion yarn used is The length is 16mm, and its proportion in the length direction is 56%. The mixed rate of the fused yarn in the obtained knitted gray fabric is 56%. After refining and desizing in the cylinder (scouring agent 0.5g / l), the intermediate setting (190°C treatment for 60 seconds), 9% weight reduction processing, 130°C for 30 minutes, disperse dyeing, 160°C resin finishing (hydrophilic agent 10g / l, pH regulator 1g / l), the weight is 120g / m 2 The properties of knitted fabrics are shown in Table 1.

Embodiment 2

[0043]Using 95D-36f-polyester fused with DTY and 75D-36f-delustered polyester FDY for weaving, the organization is ordinary cotton wool, woven into knitted gray fabric on a 28G double-sided machine, and the length of the fused area of ​​the fused yarn used is 16mm, and its proportion in the length direction is 56%, the blending rate of the fused yarn in the obtained knitted gray fabric is 56%, after scouring and desizing in the cylinder (scouring agent 0.5g / l), the weight reduction rate is 12 % reduction processing, dyeing with disperse dyes at 135 degrees for 30 minutes, resin finishing at 160 degrees (hydrophilic agent 10g / l, pH regulator 1g / l), and the weight is 159g / m 2 The properties of knitted fabrics are shown in Table 1.

Embodiment 3

[0045] Using 63D-72f-polyester fused with DTY for weaving, the organization is ordinary jersey, and knitted gray fabric is woven on a 28G single-jersey machine. The length of the fused area of ​​the fused yarn used is 6mm, and its length direction The proportion above is 62%, and the mixed rate of the fused yarn in the obtained knitted gray fabric is 100%, after scouring and desizing in the cylinder (scouring agent 0.5g / l), intermediate setting (185 degrees for 60s), 130 degrees Dyeing with disperse dyes for 20 minutes, resin finishing at 160°C (hydrophilizing agent 10g / l, pH regulator 1g / l) and air beating processing (treatment at 100°C for 20min), resulting in a grammage of 64g / m 2 The properties of knitted fabrics are shown in Table 1.

Abstract

The invention discloses fake hemp knitted fabric and a production method and application thereof. More than 30wt% of yarn in the knitted fabric is polyester blended yarn with a blended area and a non-blended area, the fake hemp knitted fabric is processed through intermediate shaping and / or quantity reducing, and dynamic friction coefficient is 0.2-0.6. By the fake hemp knitted fabric, the problem that natural hemp fiber fabric is prone to deformation and crinkling is solved, and application field of the fabric is expanded. The fake hemp knitted fabric can be used for making trousers, sweaters, T-shirts, jackets, blouses and the like.

Description

technical field [0001] The invention relates to a hemp-like knitted fabric and its production method and application, in particular to a knitted fabric with natural hemp and dry feeling, its production method and application. Background technique [0002] As we all know, as an ideal textile in summer, hemp fiber fabric has the advantages of being comfortable, non-sticky, dry and breathable, but because the chemical composition of hemp is basically the same as that of cotton fiber, it is also easy to deform and wrinkle, and has poor shape retention. In addition, there are the following problems : Easy to fade when washing, not suitable for exposure to the sun, not suitable for hanging to dry, etc. For example, a linen Lycra knitted fabric is proposed in the patent document CN02109321.0. Although the obtained fabric does not irritate the skin, has a strong heat dissipation and sweat absorption capacity, and is superior in elasticity and cool feeling, due to the high content of...
