Description

Reactive printing anti-staining soaping agent composition and preparation method thereof
Technical Field
The invention relates to the field of soaping agents, in particular to an active printing anti-sticking soaping agent composition and a preparation method thereof.
Background
After the reactive dye is printed, strict and sufficient washing and soaping are generally required, the size, the floating color (the hydrolyzed dye and the unfixed dye) and the auxiliary agent on the fabric are washed in the soaping process, and the washed high polymer size, the floating color and the auxiliary agent are mixed and dissolved together and easily stain the printed fabric, so that the printed fabric is not white, the color of the colored light is changed or the color fastness is reduced.
The research of many researchers on the reactive printing soaping agent still remains in the soaping process of the reactive dyed fabric, namely, the soaping agent is mainly used for fully cleaning the flooding and the auxiliary agent and preventing the anti-staining, and the soaping agent is mainly prepared by copolymerizing acrylic acid series monomers and NVP (N-vinyl pyrrolidone) or compounding polyacrylic acid polymers and PVP (polyvinyl pyrrolidone). In the reactive printing process, the high polymer slurry is an important soaping object, and for the anti-sticking soaping of the reactive printing slurry, the reactive soaping agent used in the common dyeing process is not suitable, namely the soaping agent used in the reactive dyeing process has poor cleaning and anti-sticking effects on the high polymer slurry.
The difficulty is how to realize the anti-sticking soaping of the sizing agent on the printed fabric, because the commonly used active printing sizing agent not only contains sodium alginate and CMC and CMS which are easy to wash, the substitution degree of the sizing agent is generally not high, the sizing agent is easy to react with cotton fibers so that the binding force of the sizing agent and the fabric is stronger, the soaping is difficult, the hand feeling is poor, and the requirement of high-quality printed fabric is difficult to meet.
Researchers have made a lot of researches on active printing soaping agent, and patent CN102876516A discloses a preparation method of a novel dark color fleece printing soaping agent, which is mainly obtained by synthesizing hydroxymethyl acrylic acid, maleic anhydride and N-vinyl pyrrolidone copolymer and compounding the copolymer with the soaping agent. Has the characteristics of good cleaning performance, excellent dispersing performance, strong anti-contamination capability, good biodegradability and the like. The invention is still based on the conventional polyacrylic soaping agent structure, and the invention does not mention the cleaning effect and the anti-sticking effect of the pulp. Patent CN101531956A discloses an environment-friendly foamless anti-staining detergent and a preparation method and application thereof, the formula mainly comprises acrylic copolymer, a phosphorus-free alkali-resistant efficient chelating dispersion stabilizer and polyvinylpyrrolidone, the formula has strong cleaning capability on flooding, but the soaping effect on printing paste is not clear.
In summary of published data, most researchers still research the reactive printing soaping agent by copolymerizing an acrylic monomer and NVP or compounding the acrylic monomer and PVP. The soaping agent has better washing and anti-sticking capabilities to the floating color of the active printing, and has unsatisfactory washing to the sizing agent with stronger fiber binding force, so that the printed fabric after soaping has unsatisfactory fastness or poorer hand feeling, and the requirement of the high-quality active printing anti-sticking soaping agent cannot be met, therefore, the development of the soaping agent which has excellent washing and anti-sticking effects on the floating color, the auxiliary agent and the sizing agent is very important for improving the quality of the printed fabric.

Still more preferably, the modified polyacrylic acid copolymer has a weight average molecular weight of 105～107。
Further, the adsorption synergist is one or a mixture of two of nano silicon dioxide and nano titanium dioxide.
Further, the builder is a compound of betaine modified silicone oil and algal glycolipid, and the weight percentage ratio of the betaine modified silicone oil to the algal glycolipid is 1: 1-1: 3.

Figure BDA0002854656840000042
wherein n is 10-25, m is 10-25, and n + m is 25-35.
The second aspect of the invention provides a preparation method of the active printing anti-staining soaping agent composition, which comprises the following steps: synthesizing modified polyacrylic acid copolymer emulsion through emulsion polymerization, then mixing with an adsorption synergist and a builder, and stirring for 30min at 40-50 ℃ and 800-1000rpm to obtain the active printing anti-sticking soaping agent composition.
By adopting the technical scheme, compared with the prior art, the invention has the following technical effects:
the modified acrylic copolymer of the invention polymerizes acrylic monomers and unsaturated organosilicon monomers, effectively combines hydrophilic groups (COO-) and hydrophobic groups (silicon-containing components), and the hydrophobic groups are also adsorbed on the surface of the sizing agent in the contact and permeation processes of the hydrophilic groups and the sizing agent, so that the hydrophilicity of the sizing agent is reduced, and further the bonding force between the sizing agent and fibers can be reduced, so that the sizing agent can be easily dropped from the fibers, and the sizing agent can be fully cleaned. The nano-structured adsorption enhancer can permeate into the slurry, so that the slurry is more loose and is easier to wash. The adsorption synergist can also adsorb polyacrylic acid copolymer and builder components, and can fully clean floating color, auxiliaries, especially pulp by virtue of the cleaning and anti-sticking functions of the copolymer and the builder. The betaine modified silicone oil in the builder can disperse the copolymer after adsorbing impurities, further avoid the reverse sticking, and the seaweed glycolipid in the builder can be further combined with the washed slurry (such as CMC and CMS), and is uniformly dispersed and dissolved in the soap lotion to prevent the reverse sticking to the fabric.
