Embodiment 1

[0040] The contact angle of the cotton cloth described in Example 1 is 0°, because the hydrophilicity of the cotton cloth is excellent, and the water drop is completely spread and absorbed on the surface of the cotton cloth within 5 seconds. According to the definition of the contact angle, the contact angle of the cotton cloth is 0° °.

[0041] Example 1

[0042] Cut the cotton cloth according to the size of 10cm×15cm, after cleaning and drying, accurately weigh its mass as 1.7243g, and put the cotton cloth into the irradiation tube for later use. Prepare 100 mL of a methanol solution of N-isopropylacrylamide with a mass / volume ratio of 15 g / 100 mL (that is, 15 g of N-isopropylacrylamide per 100 mL of methanol), and add 40 mg of copper sulfate to this solution as a barrier. Polymer. Take 40mL of this solution and add it to the aforementioned irradiation tube equipped with cotton cloth. After degassing by ultrasonic vibration, vacuuming, and nitrogen gas, the irradiation tu...

Embodiment 2

[0047] Cut the nylon cloth according to the size of 10cm×15cm, after cleaning and drying, accurately weigh its mass to 0.7040g, and put the nylon cloth into the irradiation tube for later use. Prepare 100 mL of an ethanol solution of N-ethylacrylamide with a mass / volume concentration of 16.7 g / 100 mL, and add 40 mg of copper sulfate to the solution as a polymerization inhibitor. Take 40mL of this solution and add it to the aforementioned irradiation tube equipped with nylon cloth. After degassing by ultrasonic vibration, vacuuming, and nitrogen gas, the irradiation tube was sealed and placed in the cobalt source chamber for co-irradiation grafting. The absorbed dose was 30kGy. After the irradiation, the nylon cloth was taken out and purified with a Soxhlet extractor using ethanol as the purification reagent. After the purification, the anti-scald nylon cloth was dried to a constant weight, and its mass was accurately weighed to be 0.9077g. According to Formula 1, the graftin...

Embodiment 3

[0052] Cut the cotton cloth according to the size of 10cm×15cm, after cleaning and drying, accurately weigh its mass as 1.9724g, and put the cotton cloth into the irradiation tube for later use. Prepare 100 mL of an aqueous solution of N-isopropylacrylamide with a mass / volume ratio of 1 g / 100 mL, and add 40 mg of copper sulfate to the solution as a polymerization inhibitor. Take 40mL of this solution and add it to the aforementioned irradiation tube equipped with cotton cloth. After degassing by ultrasonic vibration, vacuuming, and nitrogen gas, the irradiation tube was sealed and placed in the cobalt source chamber for co-irradiation grafting. The absorbed dose was 5kGy. After the irradiation, the cotton cloth was taken out and purified in a Soxhlet extractor using methanol as the purification reagent. After the purification, the anti-scald cotton cloth was dried to constant weight, and its mass was accurately weighed to be 2.1521g. According to Formula 1, the grafting rati...

Abstract

The invention discloses a preparation method of an anti-scald textile. The preparation method is characterized by comprising the following step of: in a solvent, under the oxygen free condition and the protection of inert gases, irradiating a textile and a graft monomer to enable the textile and the graft monomer to carry out co-irradiation grafting reaction, thus obtaining the anti-scald textile, wherein the graft monomer is a compound with thermo-sensitivity, and the hydrophilicity of the graft monomer can be converted to hydrophobicity at the temperature above 32 DEG C. The invention also discloses an anti-scald textile prepared by the method. The preparation method and the anti-scald textile have the following effects: the preparation method is easy and convenient to operate; the durability of the textile in an anti-scald effect is greatly increased; the use thickness of the anti-scald textile is simultaneously reduced to a lower level; the anti-scald textile disclosed by the invention can realize the anti-scald effect on the premise of retaining inherent skin friendliness and water permeability; and the anti-scald textile can maintain a good anti-scald effect after being used repeatedly.

Description

technical field [0001] The method relates to a finishing method of textiles, in particular to a temperature-sensitive and anti-scald textile and a preparation method thereof. Background technique [0002] In daily life and work, burns often occur. Especially after the textile is soaked, the residue of high temperature water contacts with the skin and further aggravates the burn. Therefore, it is imminent to develop anti-scald textiles. [0003] At present, the main method of textile anti-scalding is to thicken the thickness of textiles and adopt special functional finishing, mainly adopt composite textiles, that is, textile lining or outer covering heat insulation layer. The thermal insulation layer of composite textiles mainly includes the following types: nanoporous thermal insulation materials, inorganic mineral fiber thermal insulation materials, and organic-metal composite materials. [0004] For general textiles, anti-scald is mainly to thicken its thickness and red...
