[0046] In order to make the purpose, technical solution and advantages of the utility model more concise and clear, the utility model is described with the following specific embodiments, but the utility model is by no means limited to these embodiments. The embodiments described below are only preferred embodiments of the utility model, which can be used to describe the utility model and cannot be understood as limiting the scope of the utility model. It should be pointed out that any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.

[0047] In order to better illustrate the present invention, the present invention is further described below in conjunction with the embodiments. The following are specific embodiments.

[0048] Example 1

[0049] See also Figure 1 In this embodiment, a denim fabric is prepared by a double warp beam weaving method, and the specific preparation method is as follows:

[0050] (1) The first warp yarn is made of 21S pure cotton yarn with a twist of 71 twists / 10cm, and the first warp yarn is piece-dyed; the second warp yarn is made of a blended yarn of polyester staple fiber and viscose fiber, wherein the ratio of polyester staple fiber to viscose fiber is 70:30; the yarn count of the second warp yarn is 32S, and the twist is 86 twists / 10cm.

[0051] (2) The weft yarn is made of elastic core-spun yarn, the outer covering is a blended yarn layer formed by polyester staple fiber and viscose fiber in a ratio of 70:30, and the yarn core is a spandex elastic yarn with a fineness of 20D; the yarn count of the weft yarn is 32S, and the yarn twist is 99 twists / 10cm.

[0052] (3) The ratio of the number of the first warp yarn to the second warp yarn is 1:1, and the regular threading pattern is: the ground yarn is threaded through 1.2.3.4.5.6.7.8.9.10, and the edge yarn is threaded through 11.12, among which the 1.3.5.7.9 heald frames are threaded through the first warp yarn (i.e. the lower axis), and the 2.4.6.8.10 heald frames are threaded through the second warp yarn (i.e. the upper axis).

[0053] (4) Fabric structure and machine process design: The warp and weft density is 100×70, and the fabric structure is 4 / 1 right oblique + 2 / 3 left oblique.

[0054] (5) The fabric weaving process is as follows: winding, warping, sizing, drawing-in, weaving, finishing, and finished product. The finishing processes include singeing, desizing, stentering, skewing, and shrinkage prevention.

[0055] Since the second warp yarn is finer than the first warp yarn, the first warp yarn and the weft yarn form a 4 / 1 right slant when viewed from the front of the fabric, the warp tightness is 85.2%, and the twill texture on the cloth surface is clear; the back side fabric base is 2 / 3 left slant, and the weft tightness is 42.5%. The resulting fabric is lighter, thinner, softer to the touch, and has good elasticity.

[0056] Comparative Example 1

[0057] This comparative example adopts a double warp beam weaving method to prepare a denim fabric, and the specific preparation method is as follows:

[0058] (1) The first warp yarn is made of 21S pure cotton yarn with a twist of 71 twists / 10cm, and the first warp yarn is piece-dyed; the second warp yarn is made of a blended yarn of polyester staple fiber and viscose fiber, wherein the ratio of polyester staple fiber to viscose fiber is 70:30; the yarn count of the second warp yarn is 32S, and the twist is 86 twists / 10cm.

[0059] (2) The weft yarn is made of elastic core-spun yarn, the outer covering is a blended yarn formed by polyester staple fiber and viscose fiber in a ratio of 70:30, and the yarn core is a spandex elastic yarn with a fineness of 20D; the yarn count of the weft yarn is 32S, and the yarn twist is 99 twists / 10cm.

[0060] (3) The ratio of the number of the first warp yarn to the second warp yarn is 1:1, and the regular threading pattern is: the ground yarn is threaded through 1.2.3.4.5.6.7.8.9.10, and the edge yarn is threaded through 11.12, among which the 1.3.5.7.9 heald frames are threaded through the first warp yarn (i.e. the lower axis), and the 2.4.6.8.10 heald frames are threaded through the second warp yarn (i.e. the upper axis).

[0061] (4) Fabric structure and machine process design: The warp and weft density is 100×70, and the fabric structure is 3 / 1 right oblique + 1 / 1 left oblique.

[0062] (5) The fabric weaving process is as follows: winding, warping, sizing, drawing-in, weaving, finishing, and finished product. The finishing processes include singeing, desizing, stentering, skewing, and shrinkage prevention.

[0063] The denim fabric obtained in this comparative example has a warp tightness of 76.8% and a weft tightness of 52.2%.

[0064] Performance Testing

[0065] (1) The elastic extensibility, elastic growth rate and elastic rebound rate of the denim fabrics prepared in the examples and comparative examples were measured according to the method specified in ASTM D3107.

[0066] (2) Softness: Ten testers touch the same batch of fabrics for 3 to 5 seconds and give a softness evaluation. The four levels are divided into comfortable, soft, soft-, and stiff from soft to stiff. The majority evaluation shall prevail.

[0067] (3) Twill texture clarity: Ten inspectors visually observe the twill texture and evaluate the texture recognition. The texture clarity is divided into three levels: "very clear", "generally clear" and "unclear". The majority evaluation shall prevail.

[0068] The performance test data of the embodiments and comparative examples are shown in Table 1 below:

[0069] Table 1

[0070]

[0071] As can be seen from Table 1, Example 1 adopts the method of the present application to prepare a denim fabric with a fabric structure of 3 / 1 right oblique + 1 / 1 left oblique, and the obtained denim fabric is soft and comfortable, with a clear twill texture and good elasticity. However, the fabric structure of the denim fabric prepared in Comparative Example 1 adopts a fabric structure of 3 / 1 right oblique + 1 / 1 left oblique, and the obtained denim fabric is not as soft and has a twill clarity as Example 1, and its elasticity is also not as good as Example 1.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0073] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims, and the description can be used to interpret the content of the claims.
