Problems solved by technology

[0003] The object of the present invention is to provide a thermal insulation suit fabric and its preparation process. The fabric is prepared by grafting phase change microcapsule emulsion on the surface of epoxy anti-oxidation fiber, and then weaving and then weaving, wherein the epoxy anti-oxidation fiber There are a large number of epoxy groups grafted on the surface, and the capsule material on the surface of the microcapsules contains a large number of amino groups, which can react with the epoxy groups on the surface of the epoxy anti-oxidation fiber, so that the microcapsules are evenly grafted on the ring. The surface of the oxygen-resistant fiber, the prepared fiber has a high temperature-regulating effect, which makes the prepared fabric have a uniform high thermal resistance effect, improves the thermal insulation performance of the fabric, and effectively solves the problem that the existing thermal surface is usually prepared through the fiber. Introducing temperature-regulating agents or thermal insulation additives in the process, but due to the poor compatibility between the fiber and these additives, the thermal insulation performance is greatly reduced

Embodiment 1

[0024] The concrete preparation process of phase change microcapsule emulsion is as follows:

[0025] Step 1: Weigh 3.1g of sodium dodecylbenzenesulfonate, 10g of tetradecyl alcohol and 12g of water into a reaction vessel and raise the temperature to 65-70°C and stir and mix for 10-15min to obtain an aqueous phase;

[0026] Step 2: Weigh 10g of polyethylene glycol 400 and add it to water and stir to dissolve, then add 3.6g of isophorone diisocyanate to it, mix well, add 2.4g of the water phase prepared in step 1 to it, and then heat up to 50- Stir and react at 55° C. for 10-12 hours to obtain a phase-change microcapsule emulsion.

Embodiment 2

[0028] The concrete preparation process of phase change microcapsule emulsion is as follows:

[0029] Step 1: Weigh 3.1g of sodium dodecylbenzenesulfonate, 10g of tetradecyl alcohol and 12g of water into a reaction vessel and raise the temperature to 65-70°C and stir and mix for 10-15min to obtain an aqueous phase;

[0030]Step 2: Weigh 10g of methyl acrylate and add it into ethanol and stir to dissolve, then add 4.3g of benzoyl peroxide and 11.3g of isobutyl acrylate to it, mix well and add 2.4g of the water phase prepared in step 1 to it, Then the temperature was raised to 80-85° C. and stirred for 10-12 hours to obtain a phase-change microcapsule emulsion.

Embodiment 3

[0032] The concrete preparation process of antioxidant is as follows:

[0033] (1) Weigh 10 g of acrylic acid and add it to 30 g of thionyl chloride solution, heat up to 60-70° C. for reflux reaction for 4-5 hours, and then carry out vacuum distillation to obtain acryloyl chloride;

[0034] (2) Add 10g of 2,4-dihydroxybenzophenone and 90mL of acetone into the reaction kettle at the same time, and add phosphoric acid solution to it to adjust the pH of the solution to 1, then raise the temperature to 60-65°C and pour it into the reaction vessel drop by drop Add 12.3g of the acryloyl chloride prepared in step (1), raise the temperature to 90-95°C and stir for 8-9h after the addition is complete, then add 2.3g of anhydrous aluminum chloride to the reaction kettle in portions, and raise the temperature to 160-165°C heat preservation reaction for 3-4h, then lower the temperature to 50-60°C, and add 1mol / L hydrochloric acid solution to it, stir and react for 1-1.5h, then stand for st...

Abstract

The invention discloses a thermal insulation suit fabric. The thermal insulation suit fabric is obtained by grafting a phase change microcapsule emulsion on the surface of an epoxy antioxidant fiber to obtain a thermal insulation fiber, weaving the thermal insulation fiber after spinning, and thus obtaining the thermal insulation suit fabric. The suit fabric is prepared by grafting the phase-change microcapsule emulsion on the surface of the epoxy antioxidant fiber, and then spinning and weaving, a large number of epoxy groups are grafted on the surface of the epoxy antioxidant fiber, a largenumber of amino groups are contained on a microcapsule surface capsule material, wherein amino can react with epoxy groups on the surface of the epoxy antioxidant fiber, so that the microcapsules areuniformly grafted on the surface of the epoxy antioxidant fiber, and the prepared fiber has a relatively high temperature regulating effect, so that the prepared fabric has a uniform high-heat-resistance effect, and the thermal insulation property of the fabric is improved.

Description

technical field [0001] The invention belongs to the field of fabric preparation, and relates to a thermal insulation suit fabric and a preparation process thereof. Background technique [0002] Suits are usually the first choice for employees of companies and government agencies to wear men's clothing on more formal occasions. The reason why suits are prosperous for a long time is that they have profound cultural connotations. The mainstream suit culture is often used by people. Labeled as "educated, educated, gentlemanly, and authoritative", the main features of suits are crisp appearance, smooth lines, and comfortable wearing. Therefore, in order to show the demeanor and smoothness, it is usually not possible to wear too many clothes inside when wearing a suit, so the thermal performance of the suit is particularly important. The existing thermal surface is usually introduced by introducing temperature regulators or thermal insulation additives during the fiber preparation...
