Problems solved by technology

And the most common solution is a composite fabric, such as the denim fabric disclosed in patent document CN108527978A, a layer of thermal fabric is attached to the denim fabric by sewing or bonding. Peeling, the shedding part will easily cause the fabric to wrinkle, and the layer in contact with the skin is often not comfortable enough, and the fabric is not elastic enough, which is not conducive to sports and comfort

Embodiment 1

[0039] The warp yarn of the thermal insulation denim fabric with four-sided elasticity of the present invention is divided into two parts, which are the outer warp yarn and the inner warp yarn respectively. There are two systems for the surface warp yarn, which are indigo cotton yarn and indigo cotton+PBT core-spun yarn; there are two systems for the inner warp yarn, which are acrylic / modal blended yarn and acrylic / modal+PBT core-spun yarn.

[0040] The indigo cotton yarn count of the front warp is 16S, the indigo cotton+PBT core-spun yarn is 16S+75D / 24F, the inner warp acrylic / modal blended yarn is 21S, and the acrylic / modal+PBT core-spun yarn is 21S+75D / 24F.

[0041] Before weaving on the machine, warp warping, sizing, and warp threading are required.

[0042] Step 1 Warping: There are four different performance yarns in the warp yarns, so the batch warping method is selected, and four warp beams are warped respectively. Calculate the required number of warp yarns accordi...

Embodiment 2

[0049] In this embodiment, as figure 2 As shown in the figure, the binding method is that the surface warp is connected to the inner weft, that is, the surface warp and the inner weft are intertwined. The rest are the same as in Example 1.

[0050] The invention shows a four-sided elastic thermal denim fabric, and the warp yarn system adopts a four-axis weaving process, which ensures the uniformity of the weaving tension of the elastic warp yarn and the non-elastic warp yarn on the upper machine. The warp and weft yarns use elastic core-spun yarn respectively, which endows the fabric with elasticity on all sides of the warp and weft, effectively improving the sports comfort of the denim fabric. The fabric adopts a double-layer bonding structure, and the inner layer of the fabric and the skin contact part are made of functional acrylic modal yarn, which can effectively improve the thermal resistance value and truly achieve the characteristics of winter denim fabrics that are ...

Abstract

A kind of elastic thermal denim fabric adopts woven technology, and the fabric structure adopts double-layer knotted structure, which is divided into surface layer and inner layer. The surface layer is a denim layer and the inner layer is a thermal insulation layer. Warp warping adopts four weaving shaft technology. The surface weave of the fabric is 3 / 1 right twill weave, and the inner weave is 1 / 3 right twill weave. Both the outer and inner weaves use dual-system warp yarns, which are the basic system yarns and the elastic system core-spun yarns, and the outer and inner weaves use the same system of weft yarns, which are elastic core-spun yarns. The double-layer knotted structure ensures the softness and comfort of the fabric. The elastic yarn of the warp and weft system effectively improves the four-sided elasticity of the denim fabric, and the inner fabric is made of acrylic modal blended yarn, which ensures the delicateness and softness of the fabric in contact with the skin. It meets the needs of winter denim fabrics for four-sided elasticity and warmth retention.

Description

technical field [0001] The invention relates to the technical field of textile fabrics. Specifically, an elastic warm denim fabric and a production method thereof are provided. Background technique [0002] With the improvement of the quality of life, consumers have higher and higher requirements for dress comfort. Traditional denim fabrics are generally weft elastic fabrics or non-elastic fabrics. Thin denim fabrics are mainly suitable for spring and summer seasons. Generally, the yarn counts selected are finer, and yarns with different properties are used to achieve light, thin and comfortable performance. Thick denim fabrics are mainly suitable for autumn and winter seasons. Generally, the thick and warm properties of the fabric can be achieved by changing the fabric structure, or using thicker yarns, or through composite fabrics. The thick denim fabrics produced by the prior art are generally weft elastic, and when the human body is in motion, the requirements for str...
