Description

Method for developing color on fabric

The invention relates to a method for weaving and dyeing fabrics, in particular to a method for developing color on a fabric. The original yarn is woven into a pattern and then developed through a pigment with corresponding characteristics. In addition to quickly confirming the finished product, it also reduces the hoarding cost. And modification costs.

The traditional method of making patterned fabrics is to dye the raw yarns separately to form colored yarns of different colors, and then weave each colored yarn to form a fabric according to a predetermined pattern. A single raw yarn usually needs to reach a predetermined tonnage before it can be dyed. Machine dyeing, the dyed yarn needs time to wait for the pigment to dry, and the dried colored yarn will be woven into a fabric with a pattern.

The disadvantages of the above-mentioned conventional techniques are as follows:

1. The finished product is made at a slow speed: it takes time to dye a large number of raw yarns, and it takes time to dry the colored yarn after dyeing, and then it will be made into a patterned fabric, so the finished product takes a long time.

2. High modification cost: If the dyed yarn does not match the expected color, or if the customer wants to change the color, the dyed yarn will become a stockpile, which will cause additional accumulation and modification costs.

The invention provides a method for coloring a pattern on a fabric, the steps include: a. Using nylon fiber, cationic polyester yarn, and polyester fiber raw yarn to weave a knitted fabric with a pattern; b. Simultaneously putting different into the dyeing machine 3 types of dyes: acid dyes and cationic dyes And disperse dyes; c. Adding dyeing aid, leveling agent and retarder, dyeing aid refers to the addition of acetic acid, the ratio of 1 liter of water to 1 gram of acetic acid, adjusted to pH 4 to pH 5 Within the range, leveling agent refers to the leveling agent for nylon fiber, 1 gram of leveling agent is added to the fabric with a ratio of 0.1 kg, and retarding agent refers to the addition of thenardite, with a ratio of 1,000 grams of water to 1 gram of Glauber's salt; d. The knitted fabric after weaving is put into the dyeing machine for impregnation, and the patterns woven from different raw yarns match the dyes with corresponding characteristics, so that the finished fabric pattern after taking out shows a predetermined color.

By the above method, the advantages of the present invention are:

1.Fast color confirmation of finished products: After weaving 3 kinds of raw yarns into a patterned fabric, put them into the dyeing vat with mixed colors, and then take out the finished fabrics, you can see the dyed patterns.

2. Good dyeing effect: Dyeing additives can improve the dyeing ability, and leveling agent can make nylon fiber dye uniformly. The retarder is Glauber's salt corresponding cationic polyester yarn, which can slow the dyeing of cationic polyester yarn and control the coloring. Speed approximates the coloring speed of the three types of cloth, reduces the possibility of color blooming, and achieves quality control. In addition, thenardite can increase the vividness of the cationic polyester yarn after dyeing, making the color more vivid.

3. Low cost: In this case, the original yarn is woven with the pattern first, and then put into the dyeing machine for coloring. After dyeing, you can ask the customer to confirm whether the color matching is correct and reduce the stocking cost and modification cost.

As shown in FIG. 1, the present invention discloses a method for coloring a pattern on a fabric. The steps include: a. Three kinds of raw yarns of nylon fiber, cationic polyester yarn, and polyester fiber are passed through according to customer requirements or a predetermined pattern. The computer jacquard machine weaves into a knitted fabric with a pattern, which can be any combination of nylon fiber, cationic polyester yarn, and polyester fiber; b. Put a total of 3 different colors of dye into the dyeing machine at the same time, They are acid dyes, cationic dyes, and disperse dyes. Among them, nylon fibers absorb acid dyes, cationic polyester yarns absorb cationic dyes, and polyester fibers absorb disperse dyes. The color depth of the above-mentioned intermediate disperse dyes needs to be lighter than that of acid dyes and Cationic dyes; c. Dyeing aids, levelling agents and retarders are added. Dyeing aids refer to the addition of acetic acid, 1 gram of water and 1 gram of acetic acid, and the pH is adjusted to the range of pH 4 to pH 5. Here, the leveling agent refers to the leveling agent for nylon fiber, and 1 gram of leveling agent is added to the cloth with a ratio of 0.1 kg, and the retarding agent refers to the addition of thenardite, and the ratio is 1000 grams of water to 1 gram. Glauber's salt;. D knitted fabric into dip the dyeing machine, different raw yarn woven pattern matching dye corresponding to the characteristics of the pattern based on the extracted finished cloth according to the original yarn characteristics and corresponding dyes exhibit a predetermined color.

Next, referring to FIG. 2A and FIG. 2B and matching with FIG. 1, a finished fabric product 10 dyed by using the above method in this case is disclosed. The specific implementation process is as follows: a. First use nylon fiber, cationic polyester yarn, and polyester fiber raw yarn. Knitting fabrics with a plurality of first patterns 11, a plurality of second patterns 12, and a plurality of third patterns 13 are knitted by a computer jacquard machine; among the above, the first patterns 11 are woven from polyester fibers, and the second Pattern 12 is woven from nylon fibers, and the third patterns 13 are made of cationic polyester yarn Weaving, the woven pattern can be, for example, the first pattern 11, the second pattern 12, and the third pattern 13 in FIG. 2A are trapezoids of different sizes, and the first pattern 11 in FIG. 2B A pattern 11, the second pattern 12, and the third pattern 13 are patterned in a radial triangle. The above-mentioned first pattern 11, the second pattern 12, and the third pattern 13 may be arbitrary Combination; b. Put the acid dye, cationic dye and disperse dye in the dyeing machine at the same time. If the disperse dye is used with too dark color, the acid dye and cationic dye will not be able to color nylon fiber and cationic polyester yarn, so When the above three dyes are used at the same time, the color of the disperse dye must be light-colored pigments so as not to affect the coloring of nylon fibers and cationic polyester yarns. In other words, the color depth of the disperse dye needs to be lighter than that of the acid dyes and cationic dyes. For example: acid dyes, cationic dyes and disperse dyes are blue, brown, and white in order; c. Then add dyeing aids, leveling agents and retarding dyes. Dyeing aid means adding B Add 1 gram of acetic acid in a ratio of 1 liter of water, and adjust it to a pH range of 4 to 5. The leveling agent refers to a leveling agent for nylon fibers. Add 1 gram of cloth to a ratio of 0.1 kg of cloth. Leveling agent and retarding dye refers to the addition of thenardite, with a ratio of 1000 grams of water to 1 gram of thenardite; in the above, the dyeing aid can improve the coloring ability, and the leveling agent can make the nylon fiber uniformly dyed. It is a cationic polyester yarn corresponding to Glauber's salt system, which can slow the dyeing of cationic polyester yarn, control the coloring speed to approximate the coloring speed of three kinds of fabrics, reduce the possibility of color blooming, and achieve quality control. In addition, Glauber's salt can increase the dyeing of cationic polyester yarn. The vividness of the back makes the color more vivid; d. Put the knitted knitted fabric into the dyeing machine for dip dyeing. Although the dyeing machine will mix the three kinds of dyes in the dyeing machine, it will show a darker single color, but according to the nylon fiber absorbs the acid dye, Cationic polyester yarn absorbs cationic dyes, polyester fibers absorb disperse dyes, knitting The first pattern 11, the second pattern 12, and the third pattern 13 on the cloth are dyed with corresponding characteristics, for example, the first pattern 11 in FIG. 2A is dyed white (polyester fiber weave). Made with disperse dyes), the second patterns 12 are dyed blue (weaving nylon fibers and colored with acid dyes) and the third patterns 13 are dyed brown (cationic polyester yarn weaving) (Colored with cationic dyes), whereby the patterns woven from different raw yarns match the dyes with corresponding characteristics, so that the patterns on the finished fabric after taking out make the patterns different according to the characteristics of the raw yarn and the corresponding dyes. colour.

The proportion of the dye is related to the amount of cloth and the color depth. Therefore, the proportion of the dye into the dyeing machine will be adjusted according to the above requirements.
