The invention discloses a preparation method of a composite functional fabric with antimicrobial, anti-ultraviolet, deodorization and self-cleaning functions. The preparation method comprises the steps of preparing an activated modified treatment liquid, preparing a nano-titania dispersion liquid, processing fabrics by virtue of the activated modified treatment liquid, processing the fabrics by virtue of the nano-titania dispersion liquid, and the like. After the composite functional fabric is processed, the UPF value is more than 100, the deodorization rate is more than 95%, the photocatalysis self-cleaning fading rate of the composite functional fabric to chili oil is 96.7%, and the antibacterial rate (to staphylococcus) is 98.6%; after the composite functional fabric is washed for ten times in families, the UPF value is more than 50, the deodorization rate of the composite functional fabric to substances (including ammonia gas, formaldehyde, acetaldehyde, sulfureted hydrogen, nicotine and trimethylamine) is more than 90%, the photocatalysis self-cleaning fading rate of the composite functional fabric to chili oil is 93.9%, and the antibacterial rate (to staphylococcus) is 95.8%.

Preparation method of polyurethane modified organic silicon multipolymer fabric softening agent

ActiveCN103951809AImprove hydrophilicityImprove wearing moisture absorptionGrip property fibresEpoxyPolyethylene glycol
The invention discloses a preparation method of a polyurethane modified organic silicon multipolymer fabric softening agent. The preparation method comprises the following steps: firstly preparing a polyurethane prepolymer by using polyethylene glycol 2000 and isophorone diisocyanate; then preparing alkylhydroxyl-containing silicone oil by using di-n-butyl amine, epoxy 1,3-bis(3-glycidoxypropyl)-1,1,3,3-tetramethyldisiloxane and octamethyl cyclotetrasiloxane; reacting the polyurethane prepolymer with the alkylhydroxyl-containing silicone oil so as to obtain a polyurethane organic silicon multipolymer; and finally adding deionized water, and emulsifying so as to obtain the polyurethane modified organic silicon multipolymer fabric softening agent. The preparation method of the polyurethane modified organic silicon multipolymer fabric softening agent has the beneficial effects that urethane groups and urethane are introduced into organic silicon and serve as hard chain segments for generation of physical crosslinking, meanwhile, polyether is introduced and serves as a hydrophilic chain segment, the problem that as an amino silicon oil softening agent is easy to yellow and demulsify, oil patches are formed on fabrics, is solved, the hydrophilic performance of the fabrics subjected to soft finish is improved, the wearing hygroscopicity of the fabrics is improved, and the durability of the fabrics is good.

Dyeing and finishing process for improving color fastness to light of light-colored fabric of FDY (Fully Drawn Yarn) polyester filament yarn warp and weft four-way elastic textile

The invention discloses a dyeing and finishing process for improving the color fastness to light of a light-colored fabric of an FDY (Fully Drawn Yarn) polyester filament yarn warp and weft four-way elastic textile. The dyeing and finishing process comprises a dyeing process; a formula of a dyeing auxiliary adopted in the dyeing process comprises the following components: 0.5g / L to 1g / L of high-efficiency dispersant, 2g / L to 3g / L of chelating dispersant, 0.3g / L to 0.5g / L of 99 percent glacial acetic acid, X percent (o.w.f.) (on Weight the Fabric) of disperse yellow AM-2R, Y percent (o.w.f.) of disperse red AM-SLR and Z percent (o.w.f.) of disperse blue AM-SLR, wherein the sum of X, Y and Z is not more than 0.5, and a bath ratio is 1: (3 to 4). According to the dyeing and finishing process, the light-colored fabric of the FDY polyester filament yarn warp and weft four-way elastic textile which does not contain a fluorescent whitening agent and is obtained by being dyed by a disperse dye with color fastness to high sunlight is used as greige cloth; the color fastness to light which is up to a rating of 5 to 6 is realized through the specific dyeing and finishing process.

Durable finishes for textiles

The present invention relates to textile treatment compositions for imparting desirable characteristics durably to textile fibers and fabrics, including softness, hydrophobicity, oleophobicity, surface lubricity, abrasion resistance, tear resistance, improved drape, and pilling resistance. More particularly, in one embodiment, the invention is directed to preparations that comprise a carboxylate-functionalized fluorinated polymer and a catalyst that is capable of forming reactive anhydride rings between carboxyl groups on the polymer. In another embodiment, the invention is directed to preparations comprising a polymeric softener having at least one anhydride functional group or at least one reactive group capable of forming an anhydride functional group, together with a catalyst for forming anhydrides from the reactive group or groups. In either embodiment, the resulting reactive anhydride rings bind to substrates, such as textiles and other webs, having free sulfhydryl, alcohol, or amine groups. The invention is further directed to the process for treating textiles and other webs with desirable finishes durable to repeated cleanings. This invention is further directed to the yarns, fibers, fabrics, textiles, finished goods, or nonwovens (encompassed herein under the terms “textiles” and “webs”) treated with the textile-reactive preparations of the invention. Such textiles and webs exhibit a greatly improved, durable characteristics, such as softness and/or hydrophobicity, even after multiple launderings.
