Description

Technical Field

[0001] The invention relates to the field of wax-printing imitation fabric finishing agents, in particular to a wax-printing imitation fabric hand-feel finishing agent and a preparation method and application thereof. Background Art

[0002] The production of imitation wax print fabrics adopts a highly automated and flexible process, which not only reduces labor costs and production cycles, making the cost lower, but also enables the production of various designs and styles in a shorter time, making the colors and patterns of imitation wax print fabrics diverse, meeting the diverse needs of the modern consumer market. However, the feel of imitation wax print fabrics is not as comfortable as that of real wax print fabrics, so imitation wax print fabric feel finishing agents are usually used in the finishing process of imitation wax print fabrics to make the finished fabrics show a unique feel and appearance style of thick and fluffy, soft and elastic, bright colors, and cotton texture.

[0003] However, traditional wax-printed fabric finishing agents are mainly polyacrylate or polyvinyl acetate emulsions, which have very limited effect on improving the thick feel of wax-printed fabrics. Therefore, it is necessary to provide a wax-printed fabric finishing agent that has a better effect on improving the thick feel of wax-printed fabrics and increases the thickness. Summary of the invention

[0004] Based on this, it is necessary to provide a wax-printing fabric feel finishing agent and a preparation method and application thereof to address the above problems; the wax-printing fabric feel finishing agent of the present invention can make the fabric feel thicker and fluffier, and has higher application performance.

[0012] A method for preparing the above-mentioned wax-printing fabric feel finishing agent comprises the following steps:

[0013] Under a protective atmosphere, a xanthate RAFT agent, an emulsifier, vinyl acetate, a stabilizer and water are mixed and stirred to form an emulsion, and an initiator is added to react to obtain a prepolymer emulsion;

[0014] Adding monomers in batches into the prepolymer emulsion to obtain a polymer emulsion, wherein the monomers are selected from at least one of acrylic acid, methyl acrylate, octadecyl acrylate, and hydroxyethyl acrylate;

[0015] The polymer emulsion is mixed with a cationic film, a wax emulsion and a filler to prepare the wax-printing fabric hand finishing agent;

[0016] The general chemical structure of the xanthate RAFT agent is shown in Formula (2): R1 is selected from methoxy, ethoxy, isopropoxy, tert-butoxy, 4-methoxyphenol, 4-formylphenol or 4-fluorophenol, and R3 is selected from phenethyl, methylacetoxy, ethylpropionyloxy or diethylmalonyloxy.

[0017] In one embodiment, based on 0.15-2 parts by weight of the xanthate RAFT agent, the emulsifier is 1-4 parts by weight, the vinyl acetate is 18-35 parts by weight, the stabilizer is 0.5-2.5 parts by weight, the initiator is 0.05-0.15 parts by weight, and the water is 40-50 parts by weight;

[0027] The wax-printing fabric hand-feel finishing agent of the present invention adopts a polymer emulsion with a special block structure, wherein the two-segment structure of polyvinyl acetate and polyacrylate in the polymer emulsion enables the wax-printing fabric hand-feel finishing agent to have obvious two-segment glass transition temperatures and easy self-assembly characteristics, which is beneficial to improving application performance, and the chain segment with a lower glass transition temperature can promote the polymer emulsion to penetrate into the gaps inside the fabric fibers, which is beneficial to increasing the elasticity of the fabric and making the fabric feel thicker and fluffier.

[0028] Therefore, the hand finishing agent composed of a specific ratio of polymer emulsion, cationic film, wax emulsion and filler can make the fabric feel thicker and fluffier, with higher application performance. In addition, the hand finishing agent does not contain formaldehyde, which meets the needs of green and environmentally friendly production. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] For ease of understanding of the present invention, the present invention will be described in more detail below. However, it should be understood that the present invention can be implemented in many different forms and is not limited to the embodiments or examples described herein. On the contrary, the purpose of providing these embodiments or examples is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementation methods or embodiments, and are not intended to limit the present invention. The optional scope of the term "and / or" used herein includes any one of two or more related listed items, and also includes any and all combinations of related listed items, and the combinations include any two related listed items, any more related listed items, or all related listed items.

[0033] The present invention provides a wax-printing fabric hand finishing agent, comprising 50wt%-89wt% of a polymer emulsion having a general chemical structure as shown in formula (1), 1wt%-10wt% of a cationic film, 5wt%-10wt% of a wax emulsion and 5wt%-30wt% of a filler.

[0034]

[0035] Wherein, R1 is selected from methoxy, ethoxy, isopropoxy, tert-butoxy, 4-methoxyphenol, 4-formylphenol or 4-fluorophenol, R2 is a polymerization unit obtained by polymerization of at least one monomer selected from acrylic acid, methyl acrylate, octadecyl acrylate and hydroxyethyl acrylate, R3 is selected from phenethyl, methylacetoxy, ethylpropionyloxy or diethylmalonyloxy, m and n are both integers, m is 20-300, and n is 20-300.

[0036] The wax-print-like fabric hand-feel finishing agent of the present invention adopts a polymer emulsion with a special block structure, wherein the two-stage structure of polyvinyl acetate and polyacrylate in the polymer emulsion enables the wax-print-like fabric hand-feel finishing agent to have obvious two-stage glass transition temperatures and easy self-assembly characteristics, which is beneficial to improving application performance, and the lower glass transition temperature stage can promote the polymer emulsion to penetrate into the gaps inside the fabric fibers, which is beneficial to improving the elasticity of the fabric and making the fabric feel thicker and fluffier.

[0037] Therefore, the hand finishing agent composed of a specific ratio of polymer emulsion, cationic film, wax emulsion and filler can make the fabric feel thicker and fluffier, with higher application performance. In addition, the hand finishing agent does not contain formaldehyde, which meets the needs of green and environmentally friendly production.

[0038] Preferably, the general chemical structure formula of the polymer emulsion includes:

[0039]

[0040] In one embodiment, the cationic film is selected from quaternary ammonium salt type cationic films.

[0041] The wax emulsion includes but is not limited to silicone wax emulsion and / or polyethylene wax emulsion, which can make the finished fabric have a soft and smooth feel.

[0042] The filler includes but is not limited to at least one of sorbitol, glycerol, ethylene glycol, isopropanol or ethanol.

[0043] Preferably, the wax-printed fabric feel finishing agent comprises 60wt%-80wt% of a polymer emulsion as shown in formula (1), 2wt%-8wt% of a cationic film, 5wt%-7wt% of a wax emulsion and 13wt%-30wt% of a filler. By utilizing the synergistic effect of the components, the finished fabric presents a unique feel and appearance style of thick and fluffy, soft and elastic, bright in color and with a cotton texture.

[0044] The conventional process uses emulsion polymerization for random copolymerization to obtain acrylate-modified polyvinyl acetate emulsion as a wax-printing fabric hand finishing agent, preferably using RAFT polymerization process. However, conventional RAFT agents are very active for vinyl acetate propagation free radicals in vinyl acetate monomers, resulting in a greater tendency for them to add to the C=S double bond in the RAFT agent, resulting in an increase in the stability of the addition free radicals, resulting in a decrease in the tendency of the RAFT agent to break and release free radicals during the polymerization reaction, so it is difficult to control it to perform active free radical polymerization. Therefore, it is impossible to obtain a block polymer emulsion by using conventional RAFT agents.

[0045] Based on this, the present invention provides a method for preparing the above-mentioned imitation wax print fabric feel finishing agent, comprising the following steps:

[0046] S1, under a protective atmosphere, mixing and stirring a xanthate-type RAFT agent, an emulsifier, vinyl acetate, a stabilizer and water to form an emulsion, and then adding an initiator to initiate a reaction to obtain a prepolymer emulsion;

[0050] The invention adopts a unique xanthate RAFT agent to carry out RAFT miniemulsion polymerization, solves the problem of difficulty in active free radical polymerization of vinyl acetate monomer, and copolymerizes with acrylate monomer to form a polymer emulsion with a special block structure, so that the wax-printing-like fabric hand-feel finishing agent has obvious two-stage glass transition temperature and easy self-assembly characteristics, improves the thick and fluffy hand effect of the finished fabric, makes the application performance of the hand-feel finishing agent higher, and is also conducive to improving production efficiency, does not contain formaldehyde, and meets the requirements of green and environmentally friendly production.

[0053] The co-stabilizer includes but is not limited to at least one of hexadecane or hexadecanol.

[0054] The initiator includes but is not limited to at least one of potassium persulfate, ammonium persulfate, azobisisobutyronitrile, azobisisobutylamidine hydrochloride, cycloazobisisobutylamidine hydrochloride, and tert-butyl hydroperoxide.

[0056] In step S2, the mass ratio of the prepolymer emulsion to the monomer is preferably 7:1-9:1, more preferably 7.5:1-8.5:1.

[0057] In one embodiment, the monomer addition rate is 4 parts by weight / h to 10 parts by weight / h, more preferably 4 parts by weight / h to 6 parts by weight / h.

[0058] In one embodiment, the monomer preferably includes 40 wt % to 65 wt % of acrylic acid, 20 wt % to 30 wt % of methyl acrylate, 15 wt % to 28 wt % of octadecyl acrylate, and 0.5 wt % to 2 wt % of hydroxyethyl acrylate.
