Problems solved by technology

Starch or modified starch size is the earliest type of textile size used and used in a large amount. It has good adhesion to hydrophilic natural fibers, but poor adhesion to synthetic fibers with poor hydrophilicity. , and desizing is difficult; polyvinyl alcohol PVA size is a polymer synthetic size, which has the advantages of strong size film and good wear resistance, but its adhesion to hydrophobic fibers is not enough, and it is not easy to desizing after discharge Degradation, easy to cause environmental pollution and poison human health; acrylic size is water-based size, its sizing and desizing is simple, and it saves energy and time, non-toxic and pollution-free, and has little environmental pollution

Embodiment 1

[0021] Under nitrogen protection, add 3 g of sodium lauryl sulfate and 3 g of fatty alcohol polyoxyethylene ether into 400 mL of deionized water, and heat the water bath to 70 ° C. Add 0.5g of initiator potassium persulfate, then add 50g of styrene, 20g of methyl methacrylate, 10g of hydroxyethyl acrylate, and 1 / 10 of the mixed monomer of acrylic acid 40g, react at 85°C for 0.5 hours, then drop Add remaining mixed monomers, and polymerize for 3.5 hours. Finally, the temperature was raised to 90° C. to react for 2 hours, cooled to room temperature, and 5 g of emulsified wax was added.

[0022] The solid content of gained aqueous emulsion is 20% (solid content measuring instrument, 105 ℃, 1g, 4 hours), latex particle diameter is 0.1 μ m (Malvern particle size meter), and viscosity is 50mPa S (NDJ-5S viscometer, 30°C).

Embodiment 2

[0024] Under nitrogen protection, 1 g of sodium dodecylsulfonate was added to 400 ml of deionized water, and heated in a water bath to 90°C. Add 2g of ammonium persulfate, then add 25g of styrene, 10g of methyl methacrylate, 30g of butyl acrylate, 10g of isooctyl acrylate, 8g of octadecyl methacrylate, and 1 / 10 of the mixed monomer of 17g of methacrylic acid , reacted at 85°C for 1 hour, then added the remaining mixed monomers dropwise, and polymerized for 4 hours. Finally, the temperature was raised to 90° C., the reaction was continued for 2 hours, cooled to room temperature, and 10 g of emulsified wax was added.

[0025] The solid content of gained aqueous emulsion is 20.5% (solid content measuring instrument, 105 ℃, 1g, 4 hours), latex particle diameter is 0.15 μ m (Malvern particle diameter instrument), viscosity is 60mPa S (NDJ-5S viscometer, 30°C).

Embodiment 3

[0027] Under nitrogen protection, 5 g of sodium dodecylsulfonate and 5 g of fatty alcohol polyoxyethylene ether were added to 400 ml of deionized water, and heated in a water bath at 80°C. Add ammonium persulfate 1g, then add styrene 20g, methyl methacrylate 8g, butyl acrylate 47g, ethyl acrylate 20g, stearyl methacrylate 5g, methacrylic acid 10g, acrylic acid 5g of mixed monomer 1 / 10, react at 85°C for 1 hour, then add the remaining mixed monomers dropwise, and polymerize for 4 hours. Finally, the temperature was raised to 90° C., the reaction was continued for 2 hours, cooled to room temperature, and 15 g of emulsified wax was added.

[0028] The solid content of gained aqueous emulsion is 20.3% (solid content measuring instrument, 105 ℃, 1g, 4 hours), latex particle diameter is 0.12 μ m (Malvern particle diameter instrument), viscosity is 80mPa S (NDJ-5S viscometer, 30°C).

[0029] In summary, the water-based slurry provided by the present invention has the advantages of...

Abstract

The invention belongs to the field of textile technology, in particular to a water-base slurry for textile and a preparation method thereof, which comprises the following raw materials in part by weight: 70 to 90 parts of water, 1.0 to 10.0 parts of emulgator, 0.5 to 2.0 parts of initiator, 5 to 15 parts of emulsifying wax and 15 to 170 parts of monomers; the monomers comprise one or more of styrene, acrylic ester, methacrylate, acrylic acid and methacrylic acid; the water-base slurry is low in cost, good in stability, is non-toxic and pollution-free to the environment, and has a great application prospect in the textile field.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a textile water-based slurry and a preparation method thereof. Background technique [0002] In textile processing, warp sizing must be done before the yarn is woven into cloth to give the yarn a smooth surface, improve its strength and abrasion resistance, and increase the weavability of the yarn. [0003] The textile size currently on the market can be roughly divided into modified starch size, polyvinyl alcohol PVA size and acrylic size. Starch or modified starch size is the earliest type of textile size used and used in a large amount. It has good adhesion to hydrophilic natural fibers, but poor adhesion to synthetic fibers with poor hydrophilicity. , and desizing is difficult; polyvinyl alcohol PVA size is a polymer synthetic size, which has the advantages of strong size film and good wear resistance, but its adhesion to hydrophobic fibers is not enough, and it...
