Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of denim fabric, and particularly relates to a warm and cozy jacquard denim fabric and a preparation method thereof. BACKGROUND

[0002] Traditional denim fabric is popular for its strong and wear-resistant characteristics, but there is still room for improvement in terms of fashion and functionality. In order to increase the aesthetic appeal, patterns are often added to denim fabric through embroidery, printing or jacquard, etc. However, the embroidery method is costly and inefficient; the printed patterns are hard, prone to fading and lack of breathability; and the traditional jacquard patterns lack three-dimensionality.

[0003] In addition, in terms of warmth, the traditional method of adding wool or composite is often used, but this results in thick and hard denim fabric, which affects the original crisp style and wearing comfort of the denim fabric, and also makes it difficult to perfectly combine with pattern design.

[0004] Therefore, it is an urgent technical problem in the field to provide a new type of denim fabric that can organically combine functionality, three-dimensional pattern aesthetics and the original style of denim fabric, and a preparation method thereof. SUMMARY

[0005] The present application aims to solve the above problems and provide a warm and cozy jacquard denim fabric that integrates functionality and aesthetics, especially pattern and fabric, does not fall off, has strong three-dimensionality, low cost and high efficiency, and a preparation method thereof.

[0006] The technical solution to achieve the purpose of the present application is: a preparation method of a warm and cozy jacquard denim fabric, comprising the following steps: ① Winding: winding the face warp yarn and the back warp yarn on two weaving shafts respectively to form a double weaving shaft system.

[0007] ② Weaving-in and reed insertion: according to the preset pattern, the face warp yarn and the back warp yarn are inserted into the heddle and the reed.

[0008] ③ Weaving: using a rapier loom or an air jet loom to weave; the face weft yarn is interwoven with the face warp yarn to form the fabric surface, and the back weft yarn is interwoven with the back warp yarn and is connected with the face weft yarn.

[0009] ④ Cutting treatment: after weaving, using laser cutting or mechanical cutting, along the contour track of the preset pattern, the face warp yarn on the front of the fabric is accurately cut, and the integrity of the back warp yarn and the back weft yarn is preserved.

[0010] ⑤ Post-washing finishing: washing the fabric after cutting the face warp yarn, under the mechanical impact and kneading action of water flow, the cut end of the face warp yarn is fully loosened, raised and puffed, and covers on the face weft yarn, making the pattern area obviously raised, and finally forming a three-dimensional and fluffy jacquard pattern.

[0011] In the above step 1, the face warp yarn is indigo-dyed cotton yarn to maintain the traditional appearance of the jean fabric.

[0012] In the above step 1, the body warp yarn is indigo-dyed or undyed cotton yarn.

[0013] In the above step 3, the body weft yarn is a warm yarn, which forms a warm base layer of the fabric.

[0014] Further, the warm yarn is a chemical fiber or natural fiber with good bulkiness, and the fineness is between 150D and 300D, so as to provide sufficient warmth while not affecting the thickness of the fabric.

[0015] Further, the warm yarn is a polyester low-elasticity filament, acrylic or wool blended yarn.

[0016] In the above step 3, the face weft yarn is not limited and can be the same as or different from the body weft yarn.

[0017] In the above step 5, the washing treatment is desizing, enzyme washing, stone washing or softening treatment, and is preferably desizing or enzyme washing.

[0018] The present application has the following positive effects: (1) The warm and tuck-stitched jean fabric of the present application can naturally form a three-dimensional and fluffy tuck-stitched pattern after washing by the unique "cutting the face warp yarn" technology. The tuck-stitched pattern has a unique retro and handmade feeling, and forms a sharp contrast with the uncut area, realizing the unity of functionality and artistry, and meeting the market demand for personalized and differentiated products.

[0019] (2) The tuck-stitched pattern on the warm and tuck-stitched jean fabric of the present application is formed by the yarn of the fabric body, and the color is consistent with the fabric (such as indigo blue). The pattern is integrally formed with the fabric and will not fall off. Unlike the printing process, it will not cause problems such as discoloration and cracking. Compared with the jacquard process, it has better air permeability and stronger three-dimensionality. Compared with the expensive embroidery process, it has high efficiency and low cost.

[0020] (3) The body weft yarn of the warm and tuck-stitched jean fabric of the present application uses a warm yarn, which gives the jean fabric excellent warmth retention performance, breaks through the seasonal limitations of traditional jean fabrics, and realizes the integration of functionality and aesthetics. DETAILED DESCRIPTION

[0021] (Example 1) The preparation method of the warm and tuck-stitched jean fabric of the present embodiment has the following steps: ① Winding: winding the face warp yarn and the body warp yarn on two weaving shafts respectively to form a double-weaving shaft system.

[0022] Wherein, the surface warp yarn is indigo dyed cotton yarn, and the inner warp yarn is white cotton yarn.

[0023] ②Warping and reeding: according to the preset pattern, the surface warp yarn and the inner warp yarn are threaded into the heddle and the reed.

[0024] ③Weaving: using a rapier loom to weave; the surface weft yarn and the surface warp yarn are interwoven to form the fabric surface, and the inner weft yarn and the inner warp yarn are interwoven and are connected with the surface weft yarn.

[0025] Wherein, the inner weft yarn is wool blended yarn, and the surface weft yarn is polyester low-elasticity yarn.

[0026] ④Cutting treatment: after weaving, using laser cutting, along the contour track of the preset pattern, the surface warp yarn located on the front of the fabric is accurately cut, and the integrity of the inner warp yarn and the inner weft yarn is preserved.

[0027] ⑤Post-washing finishing: the fabric after cutting the surface warp yarn is desized and washed, under the mechanical impact and kneading action of water flow, the cut surface warp yarn is fully loosened, raised and puffed, and covers on the surface weft yarn, so that the pattern area is obviously raised, and finally forms a three-dimensional, fluffy hook pattern.
