The invention relates to dyeing and more particularly to a process of dyeing different patterns of a textile comprising weaving different textile materials into different patterns and dyeing each pattern with a dye having a different color so that advantages such as quick identification the finished textile, great decrease of the storage cost, and great decrease of the modification cost can be obtained.
A conventional process of dyeing patterns of a textile comprises applying dyes of different colors to different textile materials respectively, and weaving the textiles materials into a finished textile having patterns of different colors. Typically, a predetermined quantity of any textile material (e.g., a number of tons) is required prior to activating a dyeing machine to dye the textile material. Further, a predetermined period of time is required to dry the dyed textile material. Thereafter, the dyed textile material is woven into a pattern on a finished textile.
However, the conventional process of dyeing patterns of a textile has the following drawbacks: Yield is low due to prolonged dyeing time, prolonged drying time, and prolonged patterns weaving time. Modification cost is very high if the color of the dyed textile material is not desired or a client wants to change the color. Further, the dyed textile materials are stored in warehouses and in turn it may incur additional storage cost and modification cost.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a process of dyeing patterns of a textile having characteristics including easy operation, wide applications, quick identification the finished textile, great decrease of the storage cost, and great decrease of the modification cost.
For achieving above and other objects, the invention provides a process of dyeing patterns of a textile, comprising weaving a plurality of patterns on a textile formed of a plurality of textile materials including nylon, cationic polyester yarn (CD yarn) and polyester; pouring acidic dye, cationic dye and dispersive dye into a dyeing machine wherein color depth of the dispersive dye is less than that of each of the acidic dye and the cationic dye; adding auxiliary coloring agent, homogeneous coloring agent and coloring retardant into the dyeing machine wherein the auxiliary coloring agent is prepared by adding 1 g of acetic acid to 1 liter of water to form a solution, and the solution is adjusted to have a pH between 4 and 5; the homogeneous coloring agent is one used by nylon, and is prepared by adding 1 g of homogeneous coloring agent to 0.1 kg of textile; and the color retardant is prepared by adding 1 g of sodium sulfate to 1,000 g of water; putting the textile in the dyeing machine to dye as a finished textile; and removing the finished textile from the dyeing machine wherein each pattern woven by a different one of the textile materials has a color corresponding to the applied dye, and the color of the patterns of the finished textile is color of the dye applied to the patterns woven by the textile material.
Preferably, nylon absorbs the acidic dye, CD yarn absorbs the cationic dye, and polyester absorbs the dispersive dye.
The invention has the following advantages and benefits in comparison with the conventional art:
Quick identification of textile color. Colors of patterns can be seen after putting a half-finished textile having patterns each woven by one of three textile materials in a dyeing machine filled with dyes and being dyed.
Quality dyeing effect. The auxiliary coloring agent can increase color applicability. The homogeneous coloring agent can dye on nylon to be homogeneous. Sodium sulfate in the coloring retardant can slow the process of applying dye to CD yarn. The three textile materials are substantially dyed at the same rate and the possibility of disturbing dye application is greatly decreased. As a result, dye quality is greatly improved. Further, sodium sulfate can increase brightness of dyed CD yarn. As a result, the produced textile is more vivid.
Cost effectiveness. After dyeing the half-finished textile having patterns in the dyeing machine, the manufacturer can invite a client to check whether the colors of the patterns are correct or not. Therefore, it is possible of greatly decreasing the storage cost and the modification cost.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

Referring to
The process of dyeing patterns on a textile comprises the step of (A) activating a computed aided jacquard loom to weave a plurality of first patterns (see white straps of
The process of dyeing patterns on a textile further comprises the step of (B) pouring three different kinds of dye (e.g., acidic dye, cationic dye and dispersive dye) into a dyeing machine. It is noted that both the acidic dye and the cationic dye cannot be applied to both nylon and CD yarn if the applied dispersive dye has a darker color. For the sake of applying dyes to both nylon and CD yarn when above three kinds of dyes are applied, the color of the dispersive dye is selected to be lighter. In other words, color of the dispersive dye is lighter than that of each of the acidic dye and the cationic dye. For example, colors of the acidic dye, the cationic dye and the dispersive dye are blue, brown and white.
The process of dyeing patterns on a textile further comprises the step of (C) adding auxiliary coloring agent, homogeneous coloring agent and coloring retardant into the dyeing machine. The auxiliary coloring agent is prepared by adding 1 g of acetic acid to 1 liter of water to form a solution, and the solution is adjusted to have a pH between 4 and 5. The homogeneous coloring agent is one used by nylon, and is prepared by adding 1 g of homogeneous coloring agent to 0.1 kg of textile. The color retardant is prepared by adding 1 g of sodium sulfate to 1,000 g of water. The auxiliary coloring agent can increase color applicability. The homogeneous coloring agent can dye on nylon to make its color homogeneous. Sodium sulfate in the coloring retardant can slow the process of applying dye to CD yarn. The three textile materials are substantially dyed at the same rate and the possibility of disturbing dye application is greatly decreased. As a result, dye quality is greatly improved. Further, sodium sulfate can increase brightness of dyed CD yarn. As a result, the produced textile is more vivid.
The process of dyeing patterns on a textile further comprises the step of (D) putting the textile in the dyeing machine to dye as a finished textile having colorful patterns. The half-finished textile has a single dark color after the three different dyes have been poured into the dyeing machine. Advantageously, nylon absorbs the acidic dye, CD yarn absorbs the cationic dye, and polyester absorbs the dispersive dye respectively. The first, second and third patterns of the finished textile are dyed by corresponding dyes respectively. For example, the plurality of first patterns are woven by polyester and dyed by the dispersive dye to have a white color (see white straps of
The process of dyeing patterns on a textile further comprises the step of (E) removing the finished textile from the dyeing machine. Each of the first, second and third patterns woven by a different textile material have a color corresponding to the applied dye, and the color of each of the first, second and third patterns of the finished textile is the color of the applied dye associated with the textile material.
It is noted that weight percentages of the applied dyes are associated with the quantities of the textile materials and color thereof. Thus, the quantities of the dyes poured into the dying machine can be adjusted based on requirements.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
