[0055] To better illustrate the present utility model, the content of the present utility model will be further described below in conjunction with embodiments. The following are specific embodiments.
[0056] Embodiment 1
[0057] Refer to Figure 1 and Figure 2 , in this embodiment, a double-beam weaving method is used to prepare a soft and thick denim fabric 100, and the specific preparation method is as follows:
[0058] (1) The warp yarn 10 uses a blended yarn of cotton fiber and tencel fiber, where the cotton fiber content is 80% and the lyocell content is 20%; the yarn count of the warp yarn is 10S, and the yarn twist is 40 turns / 10 cm. The warp yarn is sized and dyed with indigo dye or sulfur dye.
[0059] (2) The weft yarn 20 uses two weft yarns, namely the first weft yarn 21 and the second weft yarn 22. Among them, the first weft yarn 21 is formed by twisting one strand of polyester filament 211 and one strand of nylon filament 212, and the structure of the first weft yarn 21 is as Figure 1 shown. The yarn count of the first weft yarn 21 is 15S, and the yarn twist is 43 turns / 10 cm.
[0060] The second weft yarn 22 is a double-core elastic yarn. The core layer of the double-core elastic yarn is formed by twisting a support core and an elastic core. The support core is a composite polyester filament with a fineness of 70D, and the elastic core is a spandex filament with a fineness of 40D; the outer layer of the double-core elastic yarn is a pure cotton fiber layer. The yarn count of the second weft yarn 22 is 16S, and the yarn twist is 80 turns / 10 cm.
[0061] (3) Fabric structure and loom draft design: As Figure 2 shown, the fabric structure adopts 5 / 1 left twill + 4 / 2 left twill, and the first weft yarn 21 and the second weft yarn 22 are arranged alternately at a ratio of 1:1 in sequence. The loom warp and weft density is: the warp density is 63 ends per inch, and the weft density is 60 picks per inch.
[0062] (4) The fabric weaving process flow is: winding, warping, sizing, drawing-in, weaving, after-finishing, and finished product. Among them, the after-finishing process is singeing, desizing, stentering, skewing, and shrink-proofing.
[0063] Comparative Example 1
[0064] This comparative example uses a double-beam weaving method to prepare a denim fabric. The preparation method of this comparative example is basically the same as that of Embodiment 1, except that the fabric structure of the denim fabric is different. The fabric structure of this comparative example is 3 / 1 left twill + 1 / 1 left twill.
[0065] Performance test
[0066] (1)The gram weight, breaking strength, tearing strength, Martindale abrasion resistance, weft elastic elongation and weft elastic resilience of the denim fabrics prepared in the examples and comparative examples were measured according to the methods specified in ASTM D3776, ASTM D5034, ASTM D1424, ASTM D4966 and ASTM D3107 respectively.
[0067] (2)Softness: Ten testers gave intuitive feelings by touching the same batch of fabrics for 3 - 5 s respectively, and gave softness evaluations, which were classified from soft to stiff as: comfortable, soft, soft -, stiff, four grades; the majority evaluation was taken as the standard.
[0068] The performance test data of the examples and comparative examples are shown in Table 1 below:
[0069] Table 1
[0070]
[0071] As can be seen from Table 1, the denim fabric prepared by the preparation method of the present application in the examples has the effect of comfortable and soft hand feeling, because the warp and weft yarn interlacing points of the organizational structure adopted in Example 1 are less and the structure is relatively loose. Compared with Comparative Example 1 which adopts the traditional 3 / 1 + 1 / 1 left twill weave, Example 1 improves the softness of the fabric through the improvement of the organizational structure, and the elasticity of the denim fabric is also improved. In addition, the denim fabric prepared in Example 1 also has good abrasion resistance, breaking strength and tearing strength.
[0072] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0073] The above - described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims, and the description can be used to explain the content of the claims.
