Description

How to make gradient color denim

technical field

The invention relates to the field of cloth weaving, in particular to a method for making gradient colored denim.

Background technique

Denim is a thicker yarn-dyed warp-faced cotton twill. The warp yarn is dark in color, usually indigo blue, while the weft yarn is light in color, usually light gray or boiled white yarn. The style is relatively single, lacks new ideas, and is relatively traditional. In view of this, the industry has carried out many improvement schemes to denim.

Chinese invention patent application CN1212172A discloses "the making method with light-colored ice pattern denim", is to directly make patterns with dyes on the denim, then seal the wax, and then place it in the required base color dye for dyeing. In this process, a pattern with light-colored ice patterns is produced, so that the finished product is bright in color and has a light-colored and beautiful ice pattern. The disadvantage is that the wax sealing process is cumbersome and the wax itself may have an impact on human skin.

Chinese invention patent application CN104068538A discloses "a warm-keeping fluorescent denim fabric", which forms a sandwich layer structure in which the fleece layer is inside, the denim is in the middle, and the fluorescent fabric layer is outside. The disadvantage is that the fluorescent fabric is easy to fall off.

Contents of the invention

The purpose of the present invention is to overcome the problem that the improvement scheme of the diversity of color patterns in the prior art is not perfect, and to provide a new method for making denim with gradient colors.

In order to achieve this goal, the technical solution of the present invention is as follows: the method for making gradient colored jeans is characterized in that it comprises the following steps and is executed sequentially,

Step S1, providing pure cotton balls;

Step S2, making bobbins;

Step S3, dyeing the bobbins;

Step S4, forming a warp;

Step S5, indigo warp yarn; and,

Step S6, weaving with weft after drawing in the heald.

As a preferred solution of the method for making gradient colored denim, in step S3, dyes used for dyeing are bleach-resistant dyes.

As a preferred solution of the method for making gradient colored denim, the dyes resistant to bleaching agents are Shihlin dyes or other similar reactive dyes.

As an optimal solution for the production method of gradient color denim, in step S4, the yarn used for the warp beam is obtained from the bobbin, and the density of the warp yarn is warped and paralleled according to the requirements of the denim finished product to ensure that the yarns are parallel to each other. closely arranged.

As a preferred solution of the method for making gradient colored denim, in step S5, the denim is dyed with indigo on the indigo sizing and dyeing machine.

Compared with the prior art, the present invention has at least the advantage of providing a new denim fabric manufacturing method. With the increase in the number of washings or the routine processing of garment manufacturers, the fabric will gradually change from the traditional indigo plain color to colored, giving people a novel feeling.

Description of drawings

Fig. 1 is a flowchart of an embodiment of the present invention. FIG. 2 is a schematic diagram of the operation of steps 1 to 3 in an embodiment of the present invention.

Detailed ways

The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

Please refer to Figures 1 and 2, which show the method of making gradient colored denim. The specific production method flow is as follows:

Step S1, providing pure cotton balls (a conventional step in the prior art).

Step S2, preparing bobbins (a conventional step in the prior art). Cotton threads are extracted from pure cotton balls and wound into groups of bobbins by processing equipment for later use. The number of groups of bobbins depends on the actual processing conditions. For large-scale processing, the number of groups of bobbins should be increased appropriately. For small-scale processing, the number of groups of bobbins should be appropriately reduced. In order to describe this embodiment simply and clearly, the number of bobbins in this embodiment is two groups.

Step S3, dyeing the package yarn to make the package yarn into a colored package yarn. In this embodiment, one of the groups is selected to be dyed red to obtain red bobbins. Choose another group to dye blue to get blue bobbin yarn. The dyes used for dyeing are bleach-resistant dyes (such as Shihlin dyes or other similar reactive dyes) to prevent fading after washing and bleaching.

Step S4, forming warp yarns. The yarns used for the warp beams are taken from red and/or blue cones, respectively, whereby the warp yarns are colored structures (red and blue sliver, all red or all blue). The density of the warp is based on the requirements of the denim finished product, and the warp is paralleled to ensure that the yarns are closely arranged in parallel with each other. During the warping process, the warp yarn should maintain proper tension and elasticity and maintain the consistency of the whole warp yarn. In addition, the warp yarn arrangement density should be uniform and smooth, without unevenness or unevenness. It needs to be added that the warp yarn here does not refer to a single yarn, but is composed of multiple yarns as a whole, which is a concept of a surface rather than a thread.

Step S5, indigo warp. The warp beam is dyed denim indigo through the indigo sizing and dyeing machine, and the denim indigo completely covers the colored structure of the warp yarn.

Step S6, weaving with weft after drafting (a conventional step in the prior art). The woven denim is processed by post-shrinkage setting and other post-treatments like ordinary denim before leaving the factory.

When this denim is used to make clothing or other finished products, and after conventional denim rinsing, enzyme washing or sandblasting, the red and blue colors that were originally covered by indigo will gradually appear as the indigo fades away. As the number of washing times increases, the whole denim product will gradually change from ordinary plain denim to colored strips or all-color finished products, giving people a sense of novelty and change, and adding a new variety to denim products.

The above only expresses the embodiment of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the scope of the patent for the invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
