Abstract
The invention provides a changeable dyeing process suitable for cotton cloth fabric aiming at the contradiction between individual dressing and batch production in the prior art, which comprises the following steps: soaking a cotton fabric in a leuco sodium salt solution of the vat dye with a required color until the vat dye is uniformly adsorbed by the cotton fabric, transferring the cotton fabric into a water film, spreading sodium percarbonate on the water film according to a preset pattern, gradually decomposing oxygen by the sodium percarbonate and oxidizing the leuco sodium salt of the vat dye to fix the vat dye on the cotton fabric, and washing the rest of the leuco sodium salt of the vat dye which is not fixed to form a pattern on the cotton fabric. The invention can also obtain the dyed cloth with changeable patterns through the process operation.
Description
Technical Field
The invention belongs to the technical field of dyeing, and particularly relates to a changeable dyeing process suitable for a cotton fabric.
Background
With the progress of society and the improvement of living standard of people, people have higher and higher requirements on clothes, and the colors and patterns of the clothes play an important role in the fashion design of the clothes. Particularly, when a certain pattern becomes a fashion trend, embarrassment of knocking on street, street and tail often occurs, and the personalized consumer groups are larger and larger at present, and people hope that own clothes are customized individually and are unique. However, the existing manufacturers adopt a mass production mode to reduce the production cost, and due to the profit margin of the clothes, the manufacturers cannot process each piece of clothes independently, for example, dyeing generates a unique pattern, so that individual consumer groups and the mass production mode are in contradiction.
Disclosure of Invention
Aiming at the contradiction between individual dressing and batch production in the prior art, the invention provides a changeable dyeing process suitable for cotton cloth fabric, and the dyed cloth with changeable patterns can be obtained through flow operation.
The invention adopts the following technical scheme:
a changeable dyeing process suitable for cotton cloth fabric comprises the following steps: soaking a cotton fabric in a leuco sodium salt solution of the vat dye with a required color until the vat dye is uniformly adsorbed by the cotton fabric, transferring the cotton fabric into a water film, spreading sodium percarbonate on the water film according to a preset pattern, gradually decomposing active oxygen by the sodium percarbonate and oxidizing the leuco sodium salt of the vat dye to fix the vat dye on the cotton fabric, and washing the rest of the leuco sodium salt of the vat dye which is not fixed off to form a pattern on the cotton fabric.
Preferably, the density of the sodium percarbonate relative to water is 2.1-4.0, so that the sodium percarbonate sinks into water when being scattered and falls on a cloth cover without transferring, and active oxygen is slowly released to oxidize leuco sodium salt on a local cloth cover and fix the leuco sodium salt on the cloth cover.
Preferably, the preparation method of the reduced dye leuco sodium salt solution is as follows: and adding the vat dye into an alkaline strong reducing solution, and reducing and dissolving the vat dye into a leuco sodium salt to obtain a vat dye leuco sodium salt solution.
Preferably, the thickness of the water film is based on the fact that the water film can soak cotton cloth fabric.
The invention has the following beneficial effects:
the vat dye has bright color, complete color spectrum and generally higher various fastnesses, especially the fastness to sunlight and washing is inferior to that of other dyes, and the vat dye has wide application. The sodium percarbonate is a novel oxygen bleaching agent formed by compounding sodium carbonate and hydrogen peroxide, has the dual properties of the sodium carbonate and the hydrogen peroxide, can release oxygen when meeting water to show bleaching and sterilizing effects, i.e. the invention utilizes the oxidative bleaching property of the sodium percarbonate, spreads the sodium percarbonate according to the design pattern of the fabric, spreads the position of the sodium percarbonate, and leads the sodium percarbonate to react with the leuco sodium salt of the vat dye, so that the vat dye is fixed on the cotton fabric, thereby forming the pattern; although the dyeing equipment has the preset pattern, the reaction degrees of sodium percarbonate at different positions are inconsistent, and the vat dye is dyed by adopting a leuco body, so that the color can not be controlled in time, the fixing ranges and the fixing degrees of the vat dye at different positions are different, the pattern is diversified, and the cotton cloth fabrics at different positions are different from each other, thereby meeting the individual customized consumption requirements of individual consumer groups.
Detailed Description
In order to make the technical purpose, technical solutions and advantageous effects of the present invention more clear, the technical solutions of the present invention are further described below with reference to specific embodiments.
A changeable dyeing process suitable for cotton cloth fabric comprises the following steps: the method comprises the steps of padding a cotton fabric in a sodium salt solution of indigo vat dye leuco dye by using a continuous padding machine until the vat dye is uniformly adsorbed by the cotton fabric, transferring the cotton fabric to a water film with the depth of 2cm, spraying sodium percarbonate on the water film by using air flow conveying according to a blue and white porcelain pattern, gradually decomposing oxygen by the sodium percarbonate, oxidizing the sodium salt of the vat dye leuco dye to fix the vat dye on the cotton fabric, and washing the rest of the vat dye leuco dye sodium salt which is not fixed off to form a changeable blue and white porcelain pattern on the cotton fabric. The preparation method of the leuco sodium salt solution of the vat dye comprises the following steps: and adding the vat dye into an alkaline strong reducing solution, and reducing and dissolving the vat dye into a leuco sodium salt to obtain a vat dye leuco sodium salt solution.
Finally, it should be noted that: the above embodiments are merely illustrative and not restrictive of the technical solutions of the present invention, and any equivalent substitutions and modifications or partial substitutions made without departing from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
Claims (2)
