The invention discloses a low-temperature soaping agent for reactive dyes, belonging to the soaping process of the printing and dyeing industry. The low-temperature soaping agent is formed by compounding high-efficiency surfactant and auxiliaries, and comprises the following components in percentage by weight: 5-20wt% of stearyl alcohol polyether, 10-60wt% of anion- nonionic surfactant, 1-10wt% of sodium carboxymethyl cellulose (CMC), 0.1-5wt% of polyvinylpyrrolidone (PVP), 0.1-5wt% of sodium polyacrylate (PAAS), 1-20wt% of triethanolamine (TEA), and the balance being water. The soaping agent is free of phosphor, alkylphenol polyoxyethylene ether and harmful solvent, can be biodegradable, has low foaming performance and self-chelating performance, is used for soaping reactive dyes after dyeing, has a good soaping effect at a soaping temperature of 60 DEG C, and can save energy and reduce consumption.

The invention relates to low temperature soaping powder and a preparation method thereof. So far, there has been no soaping powder which has excellent soaping performance at low temperature and decolouring performance to soaping residue. The low temperature soaping powder provided in the invention comprises, by weight, 25 to 65 parts of maleic anhydride-acrylic acid copolymer powder, 35 to 85 parts of sodium percarbonate and 35 to 85 parts of sodium perborate. The preparation method for the low temperature soaping powder comprises the following steps: with an aqueous solution of maleic anhydride-acrylic acid copolymer, sodium percarbonate and sodium perborate as raw materials, heating the aqueous solution of maleic anhydride-acrylic acid copolymer to a temperature of 70 to 90 DEG C under agitation, subjecting the aqueous solution of maleic anhydride-acrylic acid copolymer to vacuum distillation for 2 to 5 hours at a temperature of 70 to 90 DEG C and cooling the aqueous solution of maleic anhydride-acrylic acid copolymer to a temperature of 60 to 70 DEG C; subjecting the aqueous solution of maleic anhydride-acrylic acid copolymer to vacuum drying for 8 to 15 hours at a temperature of 100 to 150 DEG C, crushing dried maleic anhydride-acrylic acid copolymer and mixing crushed maleic anhydride-acrylic acid copolymer with sodium percarbonate and sodium perborate to prepare the soaping powder. The low temperature soaping powder provided in the invention has strong soaping performance, strong anti-staining performance, and decolouring performance to soaping residue.

The invention discloses an addition agent acid soaping agent for dyeing. Although the conventional soaping agent composite has good soaping function, but cannot neutralize the alkaline substances which are remained on the cloth, and the cloth is washed by water for multiple times until the pH value of the cloth is close to neutral, the cloth can be used, so a great amount of water resource is wasted. Fatty alcohol polyethenoxy ether is firstly reacted with acrylic acid or maleic acid to generate a polymerization monomer with surface activity, then under the existence of the evocating agent, the polymerization monomer is polymerized with hydrophilic monomer to generate a macromolecular polymer having dispersion chelation performance, and the macromolecular polymer is compounded with the surface active agent to obtain the acid soaping agent. The prepared acid soaping agent integrates the neutralization process and the soaping process after the dyeing of the active dye, so the process flow is greatly shortened, the water is saved, the energy is saved, the emulsion dispersion chelation performance is excellent, the loose color on the texture can be easy to wash, and the staining prevention performance is excellent.

The invention discloses a wool milling anti-staining method, comprising the following steps: (1) laying colored wool material on a white gray cloth to obtain a sample cloth, and then fixing Dupont paper on the wool material of the sample cloth On that side; (2) Put the sample cloth obtained in step (1) into the dyeing machine, soak it, add anti-dyeing agent and soda ash, run at room temperature for 4-6 minutes, then heat up to 50-60°C and run for 50-55 minutes; ( 3) Wash once with water, add acid to neutralize until the pH value is 6, remove the Dupont paper, and dry to obtain. The present invention performs a one-bath process on the wool milling process and the anti-staining process, and cooperates with optimal process conditions to reduce processes and improve production efficiency; it can also reduce production costs and save energy.

The invention belongs to the field of fine chemicals, and specifically relates to an environment-friendly acidic soaping agent and a preparation method thereof. The soaping agent comprises the following components in parts by mass: 10-30 parts of carboxyethylthiosuccinic acid, acrylic acid- 30-50 parts of 2‑acrylamide‑2 methylpropanesulfonic acid (AA / AMPS) copolymer, 20‑50 parts of sodium gluconate, 5‑10 parts of hydrolyzed polymaleic anhydride, 0.1‑2 parts of surfactant, Mixture 0.5-10 parts, water 30-50 parts. The invention acts on cotton and its blended fabrics after being dyed with reactive dyes to remove floating colors better, ensuring the color fastness and brightness of the fabrics; and the soaping agent component does not contain nitrogen and phosphorus, has strong acidity, and can It reduces the acid neutralization process before conventional soaping, reduces the pressure of wastewater discharge, saves manpower and electricity costs, and has a good market advantage.

An environmentally friendly soaping agent is disclosed. Preparation of the soaping agent includes: 1) preparing macroporous silicon dioxide, 2) preparing a chitosan solution, 3) immobilizing laccase and 4) preparing the soaping agent. The soaping agent is advantageous in that: (a) the soaping agent is free of acid washing, thus reducing environment pollution; (b) the soaping agent has excellent properties, namely, the soaping agent has good chelating, dispersing, suspending, and washing properties, and the soaping agent is capable of effectively removing flooding, protecting fabric from being contaminated by the flooding, guaranteeing the colour fastness, and making the color tune more bright and pure and the fabric surface cleaner; (c) the soaping agent can achieve low-temperature soaping, and is suitable for soaping at a temperature lower than 60 DEG C, excellent in anti-staining property and capable of reducing thermal loss; (d) foams are few; and (e) work hours are reduced and are only 30% of work hours of an original process, washing steps are largely reduced, the water using amount is only a quarter of an original water using amount, the process time is shortened, the cost and the treating load of waste water are reduced, and the pollution to the environment is reduced.
