Problems solved by technology

At present, there are three main researches on heat-retaining fabrics: (1) Heat-retaining fabrics based on some special fibers that absorb heat and heat. The kinetic energy is reduced and converted into heat energy release at the same time to achieve the purpose of moisture absorption and heat generation. However, due to the high peak temperature rise and disordered heat production in this method, it is easy to cause low-temperature burns; Add special substances to absorb solar energy and convert it into heat energy, and emit far infrared rays at the same time to achieve the purpose of heating, but the performance of this method is greatly affected by weather changes, and its heating efficiency is very low in the case of weak sunlight , and is limited to outdoors. In addition, the materials used in this method are expensive and the production cost is high; (3) Heat-generating fabrics based on phase change heat storage. The form absorbs, stores and releases heat, so as to achieve the purpose of heat absorption and heat generation, but this method is not washable, and there is a leakage problem of solid-liquid phase transition

Then adopt air-jet loom to weave, and the speed of a vehicle is controlled at 400r / min. The specifications of the woven fabric 1 are: pure cotton fabric, weight 180g / ㎡, width 150cm, yarn count 21S*21S, density 108*58 threads / 10cm.

[0026] Step 2, pre-treatment: Walk the fabric 1 in the overflow machine for two laps to make the fabric 1 run smoothly, then pump in the dissolved lye and auxiliary agent, the lye is NaOH 10g / L, and the auxiliary agent is Add O 3g / L and ABS 1g / L flatly, the dipping bath ratio is 1:30, and then run smoothly for 3 minutes to fully contact the lye with the fabric 1, then raise the temperature to 100°C at a speed of 2°C / min, and keep it warm for 20 minutes. Then lower the temperature at a rate of 1.5°C / min, drain the liquid when it drops to 80°C, wash thorou...

Embodiment 2

[0034] Step 1, weaving: first, sizing the warp yarn, the sizing formula is: PVA-217 is 2%, GH-22 is 1%, the sizing rate is 6%, the pH value is 6.8, and the vehicle speed is controlled at 25m / min. Then adopt air-jet loom to weave, and the speed of a vehicle is controlled at 600r / min. The specifications of the woven fabric 1 are: pure polyester fabric, weight 210g / ㎡, width 150cm, yarn count 21S*21S, density 108*58 threads / 10cm.

[0035] Step 2, pre-treatment: Walk the fabric 1 twice in the overflow machine to make the fabric 1 run smoothly, then pump in the dissolved lye and auxiliary agent, the lye is NaOH 15g / L, and the auxiliary agent is Add O 5g / L and ABS 3g / L flatly, the dipping bath ratio is 1:50, and then run smoothly for 5 minutes to make the lye fully contact with the fabric 1, then raise the temperature to 100°C at a speed of 4°C / min, and keep it warm for 30 minutes. Then lower the temperature at a rate of 2°C / min, drain the liquid when it drops to 80°C, wash thorough...

Embodiment 3

[0043] Step 1, weaving: first, sizing the warp yarn, the sizing formula is: PVA-217 is 3%, GH-22 is 2%, the sizing rate is 8%, the pH value is 7.4, and the vehicle speed is controlled at 20m / min. Then the air-jet loom is used for weaving, the speed is controlled at 500r / min, and the specifications of the woven fabric 1 are: polyester-cotton fabric, 80 polyester / 20 cotton, plain weave, grammage 130g / ㎡, width 150cm, yarn count 45S*45S, Density 110*76 / 10cm.

[0044] Step 2, pre-treatment: Walk the fabric 1 twice in the overflow machine to make the fabric 1 run smoothly, then pump in the dissolved lye and auxiliary agent, the lye is NaOH 12g / L, and the auxiliary agent is Add O 5g / L and ABS 1.5g / L flatly, the dipping bath ratio is 1:50, and then run smoothly for 5 minutes to make the lye fully contact with the fabric 1, then raise the temperature to 100°C at a speed of 2.5°C / min, and keep it warm for 25 minutes , then lower the temperature at a rate of 2°C / min, drain the liquid wh...

Abstract

The invention discloses a preparation method of a self-heating fabric. The technological process is: weaving→pretreatment→soft finishing→drying→heat setting→self-heating wax treatment and health care finishing→heating dripping→finished product. The self-heating wax treatment health care finishing process is: mixing tourmaline stone powder, far-infrared ceramic powder, beeswax and paraffin in a mass ratio of 10-30:5-20:10-30:10-30, heating to 70-90 ℃, and high-speed stirring to mix evenly to prepare a self-heating wax treatment mixture, then drop it on the surface of the heat-set fabric, cool and solidify at room temperature, and form self-heating wax treatment health care particles; the heating dripping process is: polyurethane elastic Crystal glue A and B are mixed evenly, vacuumized, and then dropped on the surface of self-heating wax therapy health care particles, and dried and solidified. The invention effectively prevents skin from being scalded at low temperature, eliminates the influence of weather changes on fabric properties, and at the same time endows fabrics with wax therapy and health care effects, and improves the washability of functional fabrics.
