Problems solved by technology

However, this treatment will have a certain negative impact on fabric dyeing and fabric feel.
Especially when producing high-elastic and heavy underwear for underwear, curling will bring many difficulties in degreasing, high-temperature setting, dyeing and post-processing.
[0005] Third, most of the warp-knitted fabrics meet customers' requirements for smoothness and softness of the fabric, but at the same time, there is a problem of hooking
This kind of hooking phenomenon even appears in the process of putting the product on the shelf and during the dressing process of consumers. This defect of warp knitted fabric greatly reduces the grade of the product.

Abstract

The invention discloses a warp-knitted fabric and a production method thereof, which comprises a guide bar wherein non-elastic yarns pass through the front side of a knitting machine and the 1 x 2 opening heavy warp flat tissue is knitted. Elastic yarns pass through a guide bar arranged at the back of the knitting machine and are knitted into the 1 x 1 closing warp flat tissue. The transverse and vertical elasticity of the warp-knitted fabric knitted by non-elastic yarns and elastic yarns, namely the elongation rate and the elastic modulus under the certain stretch force, are substantially consistent. The invention also discloses a production method of the warp-knitted fabric. According to the method, the elongation rate and the elastic modulus of the warp-knitted fabric under the certain stretch force are substantially consistent. Only the normal heat setting temperature is required without the adding of hardening paste, the hemming problem of the cutting edge of the fabric is overcome. Therefore, the dyeing property and the soft feeling of the fabric are improved, while the yarn hooking problem is avoided.

Description

Technical field: [0001] The invention belongs to the textile field, and in particular relates to a warp-knitted fabric and a production method thereof. Background technique: [0002] There are three major defects in the current warp knitted fabric used in the underwear industry: [0003] First of all, there is a big difference in the elasticity (rebound rate and elastic modulus) of the current warp-knitted fabrics in the warp and weft directions. In other words, it is easy to achieve the same elastic modulus in the warp and weft directions under a certain tension, but it is difficult to ensure the same elastic modulus in the warp and weft directions by stretching. Therefore, our current warp-knitted fabrics can only meet one aspect of the elastic requirements of the fabric, which has greatly limited its use in the underwear industry. [0004] Secondly, the curling problem in the cutting process will greatly affect the utilization rate of garment production and the quality ...
