Description

Technical Field

[0001] This utility model relates to the field of denim fabric technology, and in particular to an environmentally friendly blue denim fabric. Background Technology

[0002] Since its inception, denim clothing has been favored by certain groups due to its unique colors and fabric characteristics. Traditional denim fabrics are typically dyed using starch slurry combined with chemical agents such as PVA and penetrants, as shown in patent application publication number CN117721567A. However, PVA is a large-molecule organic compound that is soluble in water but difficult to degrade naturally, easily causing environmental pollution.

[0003] On the other hand, blue dye, a reducing dye based on natural amino acids, has emerged in recent years. Its production process achieves zero aniline and zero formaldehyde emissions, and it also has a short degradation cycle and high leveling properties, making it environmentally friendly. Therefore, an environmentally friendly blue denim fabric is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide an environmentally friendly blue denim fabric.

[0005] To solve the above problems, the present invention adopts the following solution:

[0006] An environmentally friendly blue denim fabric includes a first layer structure; wherein the first layer structure includes a first warp yarn and a first weft yarn; both the first warp yarn and the first weft yarn are made of biodegradable blue-dyed cotton yarn; the first warp yarn and the first weft yarn are connected by a twill weave.

[0007] Furthermore, the weave structure of the first warp yarn and the first weft yarn is one of 3 / 1 right-hand twill, 4 / 1 right-hand twill, 4 / 2 right-hand twill, or 6 / 1 right-hand twill.

[0008] Furthermore, it also includes a second layer of fabric, which includes a second warp yarn and a second weft yarn; the second warp yarn and the second weft yarn are also made of cotton yarn dyed indigo; the second warp yarn and the second weft yarn are connected to the first layer of fabric by joint splicing.

[0009] Furthermore, the second warp and the second weft yarns are in a 1 / 1 twill weave.

[0010] Furthermore, the second warp yarn is lifted and enters the first layer of the weave to interweave with the first weft yarn in the first layer of the weave; the first warp yarn sinks down and interweaves with the second weft yarn.

[0011] Furthermore, the single yarn strength of the first warp yarn is ≥18.5cN / Tex, and the single yarn strength of the first weft yarn is ≥18.5cN / Tex.

[0012] Furthermore, the first warp yarn is a Sirospun 16-count cotton yarn; the first weft yarn is also a Sirospun 16-count cotton yarn.

[0013] Furthermore, the single yarn strength of the second warp yarn is ≥15.5cN / Tex, and the single yarn strength of the second weft yarn is ≥15.5cN / Tex.

[0014] Furthermore, the second warp yarn has a count of 21 count Siro-spun cotton yarn; the second weft yarn also has a count of 21 count Siro-spun cotton yarn.

[0015] The beneficial effects of this utility model are as follows:

[0016] By using indigo-dyed yarn as the first warp and first weft yarn, the denim fabric produced is more easily degraded. Moreover, indigo is a dye based on natural amino acids, which is environmentally friendly and does not pollute the environment. Compared with traditional dyes, it is more environmentally friendly.

[0017] By adding a second layer of fabric, the denim fabric becomes thicker, retaining the characteristics of denim while increasing its thickness and properties such as windproof and abrasion resistance.

[0018] By setting the second warp and second weft yarns to have a higher count, the second layer of fabric becomes finer, making it more comfortable and skin-friendly to wear. Attached Figure Description

[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0024] Example 1:

[0025] An environmentally friendly indigo-dyed denim fabric includes a first layer structure 5; wherein the first layer structure 5 includes a first warp yarn 1 and a first weft yarn 2; both the first warp yarn 1 and the first weft yarn 2 are made of easily biodegradable indigo-dyed cotton yarn; the first warp yarn 1 and the first weft yarn 2 are connected by a twill weave. By using indigo-dyed cotton yarn, the dye itself is natural and non-toxic; furthermore, under natural conditions, the dye can complete 43% degradation after 28 days, and the impurities from garment washing will not pollute the environment. Finally, compared with spandex or other blended materials, cotton yarn is more comfortable to wear and is also easier to degrade, making it more environmentally friendly. It should be noted that the method of dyeing the cotton yarn with indigo utilizes existing methods.

[0026] The structure of the first warp yarn 1 and the first weft yarn 2 is one of 3 / 1 right-hand twill, 4 / 1 right-hand twill, 4 / 2 right-hand twill, or 6 / 1 right-hand twill. It should be noted that in this example, the twill structure is a warp-faced structure, where the warp-faced structure means that the number of warp points is greater than the number of weft points.

[0027] It also includes a second layer of structure 6, which includes a second warp yarn 3 and a second weft yarn 4; the second warp yarn 3 and the second weft yarn 4 are also made of cotton yarn dyed indigo; the second warp yarn 3 and the second weft yarn 4 are connected to the first layer of structure 5 by joint splicing.

[0028] The single yarn strength of the first warp yarn 1 is ≥18.5cN / Tex, and the single yarn strength of the first weft yarn 2 is ≥18.5cN / Tex.

[0029] The first warp yarn 1 is a Sirospun 16-count cotton yarn; the first weft yarn 2 is also a Sirospun 16-count cotton yarn. The twist coefficient of the first warp yarn 1 and the first weft yarn 2 ranges from 370 to 400. The second warp yarn 3 and the second weft yarn 4 adopt a 1 / 1 twill weave.

[0030] The second warp yarn 3 is lifted and enters the first weft layer 5, interlacing with the first weft yarn 2 in the first weft layer 5; the first warp yarn 1 sinks down and interlaces with the second weft yarn 4. The single yarn strength of the second warp yarn 3 is ≥15.5cN / Tex, and the single yarn strength of the second weft yarn 4 is ≥15.5cN / Tex. The count of the second warp yarn 3 is Siro-spun 21-count cotton yarn; the count of the second weft yarn 4 is also Siro-spun 21-count cotton yarn. The twist coefficient of the second warp yarn 3 and the second weft yarn 4 ranges from 370 to 400.

[0031] During implementation, by using indigo-dyed yarns as the first warp 1 and the first weft 2, the denim fabric produced is more easily degraded. Moreover, indigo is a dye based on natural amino acids, which is environmentally friendly and does not pollute the environment. By setting a second layer of fabric 6, the denim fabric becomes thicker, increasing its thickness and windproof and abrasion-resistant properties while retaining the characteristics of denim fabric. By setting the second warp 3 and the second weft 4 to have a higher count, the second layer of fabric 6 becomes finer, making it more comfortable and skin-friendly to wear.
