Description

Method for making denim fabric with gradient intermittent and irregular color lines

technical field

The invention relates to the field of fabric weaving, in particular to a method for making denim fabric with gradually changing intermittent and irregular colored lines.

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 CN1737233A discloses the technological process of "colored denim production process": a. yarn dyeing, first warping pure cotton yarn, and then sizing and dyeing combined machine, according to the ratio of various colored yarns required for the color of the color denim pattern Separate the pure cotton yarn into the dyeing tanks of different colors to carry out jigger dyeing and pad dyeing according to the prescriptions of various color chemicals, and at the same time dye the yarns of various colors in the proportion required for the color of the color denim pattern, then sizing and drying; b. Weaving; c . Finishing; d. Testing, packaging. The disadvantage is that the dyeing process is cumbersome, each yarn needs to be dyed, waste, and the color effect of the finished product is too bright, completely beyond the scope of denim.

Chinese invention patent application CN104068538A discloses "a kind of 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 object of the present invention is to overcome the problem of single style of denim in the prior art, and provide a novel method for making denim with gradient intermittent and irregular colored lines.

In order to achieve this goal, the technical solution of the present invention is as follows: denim fabric with gradually changing intermittent and irregular colored lines, including warp yarns and weft yarns arranged alternately; wherein, the yarns in the warp yarns are alternately changed by more than two colors And the spun colored threads with uniform or different thicknesses have an indigo dyed layer on the colored threads.

The present invention also provides a method for making denim fabric with gradient intermittent and irregular colored lines, which includes the following steps and is executed sequentially,

Step S1, providing yarn: feeding two or more raw cotton materials of different colors alternately to spin colored threads;

Step S2, forming a warp;

Step S3, indigo warp yarn; and,

Step S4, weaving with weft after drawing in the heald.

As a preferred solution of the method for making denim with gradient intermittent and irregular color lines, in step S1, dyes or pigments used for raw cotton materials are bleach-resistant dyes or pigments.

As an optimal solution for the production method of denim with gradient intermittent and irregular colored lines, in step S2, the density of the warp yarns is warped and aligned according to the requirements of the finished denim fabric to ensure that the yarns are closely arranged parallel to each other.

The present invention also provides another method for making denim fabric with gradient intermittent and irregular colored lines, which includes the following steps and is executed sequentially,

Step S1, providing yarn: feeding two or more raw cotton materials of different colors alternately to spin colored threads;

Step S2, indigo yarn;

Step S3, forming warp yarns; and,

Step S4, weaving with weft after drawing in the heald.

As a preferred solution of the method for making denim with gradient intermittent and irregular color lines, in step S1, dyes or pigments used for raw cotton materials are bleach-resistant dyes or pigments.

As an optimal solution for the production method of denim with gradient intermittent and irregular colored lines, in step S3, the density of the warp yarns is warped and aligned according to the requirements of the denim finished product, so as to ensure that the yarns are closely arranged parallel to each other.

As a preferred solution of the method for making denim with gradient intermittent and irregular colored lines, it also includes step S5 of washing.

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 conventional processing of garment manufacturers, the fabric gradually changes from the traditional indigo plain color to the finished product with some plain colors, some intermittent and irregular colored lines or all intermittent and irregular colored lines, giving people a novel feeling.

Fig. 2 is a flowchart of another 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 Fig. 1, what is shown in the figure is an embodiment. A method for making denim fabric with gradient intermittent and irregular colored lines. The specific production method flow is as follows:

1) Provide raw cotton materials with more than two different colors, and the colors may include raw cotton colors. For clear and concise description, in this embodiment, only two colors of red and blue raw cotton materials are used. What needs to be added is that the red and blue in this embodiment are formed by dyes or pigments, and the dyes or pigments used are bleach-resistant dyes or pigments, that is, after bleaching and washing, the color will not change color, and can usually Use Shihlin dyes or other anti-bleaching dyes, etc. Next, the red raw cotton and blue raw cotton are placed on the thread-making machine, fed alternately through changes, and spun red and blue alternately colored yarns with the same thickness or different thickness.

2) Use this fancy yarn as the yarn for the warp beam, warp and parallel the beam according to the warp density requirements of the denim finished product, and wind it parallel to each other tightly on the warp beam.

3) Dye the warp beam with denim indigo through the indigo dyeing machine.

4) Put the sizing-dyed warp beam on the machine for weaving.

5) After-finishing: The woven denim will go out of the factory after post-treatment such as anti-shrinkage and setting like ordinary denim. This step is a routine step for making cowboy steps, so I won’t go into details here.

Please refer to Fig. 2, another embodiment is shown in the figure. A method for making denim fabric with gradient intermittent and irregular colored lines. The specific production method flow is as follows: 1) Raw cotton materials with two or more different colors are provided, and the colors may include raw cotton colors. In order to describe clearly and concisely, in this embodiment, only raw cotton materials of two colors, primary color and green, are used. What needs to be added is that the green in this embodiment is formed by dyes or pigments, and the dyes or pigments used are bleach-resistant dyes or pigments, that is, after bleaching and washing, the green will not change color. Lin dyes or other bleach-resistant dyes, etc. Next, the primary color raw cotton material and the green raw cotton material are placed on the thread-making machine, fed alternately through changes, and spun out a yarn of primary color and green alternately with the same thickness or different changes.

2) Direct the fancy yarn to indigo.

3) After indigo, use this fancy yarn as the yarn for the warp beam, warp and parallel the beam according to the warp density requirements of the denim finished product, and wind it parallel to each other tightly on the warp beam.

4) Drawing and weaving. This step is a routine step for making cowboy steps, so I won’t go into details here.

5) After-finishing: The woven denim will go out of the factory after post-treatment such as anti-shrinkage and setting like ordinary denim. This step is a routine step for making cowboy steps, so I won’t go into details here.

It is not difficult to find that in the above two embodiments, although the denim fabrics use fancy yarns, the fancy yarns have been covered with indigo, so the woven denim fabrics do not have colored lines on the surface. When the denim is made into clothing or other finished products, after the manufacturer’s regular denim rinsing or sandblasting, or after the denim product is washed more frequently by the user, the colored lines that were originally covered by indigo will fade away. The indigo fades and gradually emerges, that is, the finished product that gradually changes from ordinary plain-colored denim to some plain-colored part-colored lines or all colored lines gives people a sense of novelty and freshness, and adds 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.
