[0096] The surface pile treatment of the warm pile warm fabric includes the following steps: the short pile in the warm pile warm fabric is subjected to carding treatment, and the floating pile is removed;

[0097] The warm pile warm fabric after the carding treatment is immersed in a reinforcing finishing agent immersion liquid, and the bath ratio is 45:1, wherein the reinforcing finishing agent in the reinforcing finishing agent immersion liquid is acrylic resin, the mass ratio of acrylic resin, toluene and ethyl acetate in the reinforcing finishing immersion liquid is 5:45:50, the immersing treatment time is 30, and the short pile outer layer is subjected to dehydration and drying after immersing;

[0098] The warm pile warm fabric after drying is subjected to carding treatment;

[0099] The combed warm fleece fabric is subjected to low-temperature heat setting treatment at a temperature of 120℃ for 15 minutes.

[0100] The warm fleece fabric undergoes a short-pile reinforcement treatment. This treatment involves using a thermoplastic resin as a reinforcement additive, mixing it with water and ethanol to prepare a self-fluffing spray solution. The thermoplastic resin is water-based polyurethane, and the mass ratio of water-based polyurethane, water, and ethanol in the self-fluffing spray solution is 5:45:50. The self-fluffing spray solution is sprayed onto the roots of the short pile. After spraying, the warm fleece fabric undergoes a heat-setting treatment at 140℃ for 15 minutes.

[0101] The warm fleece thermal fabric was impregnated with a post-treatment solution at a liquor ratio of 40:1. The mass ratio of antistatic agent, softener, water, and ethanol in the post-treatment solution was 5:3:45:25. The antistatic agent was nano-sized graphene particles, and the softener was a fluffy silicone oil softener. The impregnation time was 15 minutes. After removal, the thermal fabric was dehydrated and dried.

[0102] Performance testing

[0103] The thermal insulation performance, abrasion resistance, and elasticity of the thermal insulation textile fabrics from Examples 1-3 and the comparative example were tested. The thermal insulation performance test method was to fill glass bottles of the same material with an equal amount of hot water at a temperature of 50°C, wrap the glass bottles with a single layer of the thermal insulation textile fabrics from Examples 1-3 and the comparative example (the wrapping method and wrapping area were the same), and the fabrics were in a natural, unstretched state. After the glass bottles were placed at a temperature of 25°C for 30 minutes, the temperature of the hot water in the glass bottles was measured, and the thermal insulation rate was calculated. The thermal insulation rate was calculated as (temperature of hot water after placement / initial temperature of hot water) * 100%.

[0104] The abrasion resistance test method involves cutting circular samples with a diameter of 100 mm from the thermal textile fabrics in Examples 1-3 and the comparative example. The circular samples in Examples 1-3 are all cut from the corresponding part of the skin-friendly inner layer of the "well" pattern. A 500g weight is applied, and the weight loss of the fabric is tested after 300 revolutions of abrasion. The weight loss rate of the fabric is calculated as (weight of the sample before abrasion - weight of the sample after abrasion) / weight of the sample before abrasion * 100%.

[0105] The elasticity performance test method involves cutting three sets of strip samples, each 50 mm wide and 200 mm long, from the thermal textile fabrics in Examples 1-3 and the comparative example. The strip samples in Examples 1-3 include strip samples cut from the corresponding area of ​​the skin-friendly inner layer with a "grid" pattern, strip samples cut from the corresponding area of ​​the skin-friendly inner layer with a circumferentially expanded mesh structure, and strip samples cut from the corresponding area of ​​the skin-friendly inner layer with a diagonally expanded mesh structure. A transverse tensile test is performed using one set of strip samples. Specifically, the shorter two sides of the strip sample are clamped, and the sample is pulled to both sides with a force of 50 N on each side. The elongation of the sample is then calculated. In addition, a strip specimen was used for oblique tensile testing. The method was to clamp the two diagonals of the strip specimen and pull the specimen to both sides with a force of 50N at each corner. The elongation of the specimen was calculated as (maximum length of the specimen along the direction of force application after force application - original length of the specimen along the direction of force application) / original length of the specimen along the direction of force application * 100%. A strip specimen was used for longitudinal tensile testing. The method was to clamp the two shorter sides of the strip specimen, with the specimen horizontal, and apply a force of 100N downward to the center of the specimen with a spherical object. The distance from the lowest point of the specimen to the original horizontal plane was obtained.

[0106] After the elasticity test, the above specimens were left to stand for 30 minutes. The lengths of the transverse tensile test specimens and oblique tensile test specimens along the direction of force application were measured, and the rebound effect was calculated. The calculation method for the effect is (maximum specimen length along the direction of force application after force application - maximum specimen length along the direction of force application after standing) / maximum specimen length along the direction of force application after force application * 100%.

[0107] The test results are shown below.

[0111] Based on the above test results, it can be seen that compared to the warm plush thermal fabric in the comparative example, the short plush thermal fabric prepared using the short plush thermal textile fabric disclosed in this application, through the setting of a double-layer fabric structure and the inclusion of composite phase change yarns in the outer layer of the warm plush, results in a significantly higher thermal insulation performance than the warm plush thermal fabric in the comparative example, and also exhibits better abrasion resistance. In the abrasion resistance test, the weight of the circular sample was weighed before the abrasion action. According to the weighing results, it can be concluded that by increasing the amount of ultrafine acrylic fiber in the composite phase change yarn and the composite high-elastic yarn... The ratio of polyester fiber to bulked acrylic fiber helps reduce the weight of thermal fabrics, thereby achieving the goal of obtaining lightweight thermal textile fabrics. By setting a skin-friendly inner layer with a "grid" pattern, the elasticity of the short plush thermal fabric is improved. In addition, the skin-friendly inner layer also has an elastic grid structure with a circumferentially expanded grid structure or a diagonally deformed grid structure. This allows the short plush thermal fabric to be used with thermal fabrics with different weave structures corresponding to the skin-friendly inner layer depending on the part of the fabric to be used. This results in the thermal fabric having good elasticity and resilience under the force of different directions.
