Technical Field

The invention relates to a preparation method of a dye-resistant powder, in particular to a preparation method of a dye-resistant powder in a garment washing process.

Background

Generally, the yarn is woven into a cloth and dyed or printed to make a fabric for clothing. In the field of printing and dyeing industry, in order to make dyed fabrics show different shades of colors and show the layering or the falling feeling of the fabric colors, the fabrics need to be subjected to a washing process. The washing is a manual old-making process. There are various ways of washing water, including: general washing, stone washing, enzyme washing, sand washing, chemical washing, rinsing, destructive washing, snow washing, sand blasting, horse monkey spraying and the like. In the process of the water washing process of the fabric, the color of the fabric at part of the fabric is lightened to show the desired color difference, but the color difference is easily re-stained by the pigment remained in the water washing process, even the fabric loses elasticity or breaks elasticity, has no color contrast and low color fastness, and the fabric cannot achieve the ideal water washing effect. In order to solve the problem of dye re-adhesion, people adopt dye-repellent liquid, dye-repellent powder, dye-repellent paste and alkaline oil to prevent dye re-adhesion, and the dye re-adhesion can be divided into polyester dye-resists and surfactant dye-resists according to the components. The invention patent application No. 2018101859928 discloses a preparation method of a resist, which comprises the following steps, taking 100 parts of a novel resist as an example:

s1, preparing the following raw materials in parts by weight: 14-16 parts of polyester dye-proofing powder, 14-16 parts of fatty alcohol surfactant, 11-13 parts of polyamine color fixing agent and 57-59 parts of water;

s2, adding 57-59 parts of water into a reaction kettle, heating to 70-90 ℃, and simultaneously, rotating a stirring blade in the reaction kettle;

s3, slowly adding 14-16 parts of polyester dye-resistant powder under the rotation state of the stirring blade, rotating at the speed of 20-40 revolutions, and closing the heating device after the polyester dye-resistant powder is completely dissolved;

s4, slowly adding 14-16 parts of fatty alcohol surfactant, adding 11-13 parts of polyamine color fixing agent, stirring uniformly, and cooling to obtain the finished product of the dye-proofing powder.

The dye-resistant powder prepared by the process can be quickly dissolved in cold water; in the washing process, the effect is quickly exerted, and the elasticity and the tearing strength of the fabric are not influenced; compared with the similar products, the product has obvious price advantage; can stably carry out washing operation according to dyeing requirements, and has obvious dyeing prevention effect.

The invention patent application number 2017107026256 discloses a high-performance environment-friendly dye-proofing powder for jean ferment washing, which is prepared from hydrolysis products of fatty alcohol-polyoxyethylene ether and styrene-maleic anhydride copolymer in a mass ratio of 1: 1-3, and mixing. The preparation method of the hydrolysate of the styrene-maleic anhydride copolymer comprises the following steps:

(1): according to the molar ratio of styrene to maleic anhydride of 1: 1-5, adding styrene and maleic anhydride into a toluene solution, introducing nitrogen to drive oxygen, heating to 75-80 ℃, and preserving heat for 5-10 minutes;

(2): fully mixing an initiator and toluene, dropwise adding the mixture into the mixed solution obtained in the step (1) by using a dropping funnel, wherein the dropwise adding time is half an hour to one hour, carrying out heat preservation reaction for two to three hours after the completion of the reaction, carrying out the whole reaction under the atmosphere of nitrogen introduction, cooling and filtering after the reaction is finished, washing the obtained product for three times by using methanol, and then carrying out vacuum drying at 50-60 ℃ to obtain styrene-maleic anhydride copolymer powder;

(3): and (3) adding the styrene-maleic anhydride copolymer powder prepared in the step (2) into a sodium hydroxide solution, heating until the powder is dissolved into a transparent solution, condensing and refluxing for half an hour to one hour, cooling, transferring to a hydrochloric acid solution to separate out a precipitate, filtering and collecting the precipitate, and washing and drying to obtain a hydrolysate of the styrene-maleic anhydride copolymer.

The invention can ensure that indigo dye particles dropped off from the denim are uniformly distributed in the cellulase lotion; the preparation process is simple, the raw materials are wide in source, the economic practicality is good, the non-toxic and environment-friendly effects are achieved, the anti-rewetting effect is good, and the added value and the appearance quality of the jeans wear can be effectively improved. The solutions described in the above two patents are obvious to a person skilled in the art, and the solution claimed in the claims does not have the outstanding essential features or significant improvements. Therefore, in the actual production, how to research an applicable dye-resistant powder with obvious effect becomes a technical demand for the development of the industry.
