In recent years, great attention has been paid to the development of textile garments having superior warmth retention properties.
The heat-preservation mechanism of the fabric refers to the performance of clothing fabric, textile and the like for keeping the temperature of a covered person. When the human body is in heat balance, the comfortable temperature is about 33.4 ℃ and exceeds 37.9 ℃, and the human body feels cold and warm. According to the structural form of the fiber, the heat-insulating fabric can be divided into hollow fiber, superfine fiber and space fabric fiber. The hollow polyester fiber has the largest hollow polyester proportion in the hollow fiber, and is also most widely applied in the heat preservation clothing industry. The hollow polyester fiber has a prospect in future cross development with other subjects from filling materials, thermal clothes, thermal trousers to special protective clothing and aerospace clothing.
The literature investigation and research show that the thermal insulation performance of the polyester fabric is widely concerned, such as: chinese invention patent application No. 201820520803.3 discloses a hydrophobic double-hollow thermal polyester filament: the cross-section outline of the invention adopts a structure imitating a T shape with an included angle, and the transverse edge is provided with an inclined surface, so that water drops are difficult to adsorb on the surface, thereby better facilitating the rolling removal of the water drops and the like and achieving the effect of surface dewatering. However, the hollowness of the preparation process is difficult to control, and the wearability of the whole fiber may be influenced.
Tourmaline powder is obtained by mechanically pulverizing raw tourmaline ore after removing impurities. Tourmaline powder can be used in textile industry as environment-friendly charcoal cloth, and superfine tourmaline powder can be made into superfine fiber, and can be made into antimagnetic, dampproof, warm-keeping quilt, cotton pad, electromagnetic radiation-proof shirt, vest, insole, etc., and can also be used in rock bath, sweat stream room, light wave room, sauna facility and environment-friendly home decoration.

The testing temperature is 20 +/-2 ℃ and the humidity is 65 +/-2 percent, the testing principle is that under the specified pressure difference condition, the air flow rate which vertically passes through a given area of a sample in a certain time is measured, and the air permeability R is calculated according to the following formula.
In the formula:qvthe flow rate is the average flow rate of the gas,Athe test area is 167 a conversion factor. The fabric to be tested is subjected to standard washing by referring to a washing method of a GB/T20944.1-2007 color fastness to washing tester, the air permeability of an initial sample and a sample after 10 times of washing are tested, and the test results are shown in Table 1.
TABLE 1 air permeability of Terylene face fabrics a, b, c, d, e, f and unfinished Terylene face fabrics
As can be seen from the table 1, the air permeability ranges of the terylene fabrics a, b and c are respectively 876.1-892.5 mm/s, which are slightly lower than that of the non-finished terylene fabric, and the air permeability is within the normal range; after 10 times of water washing, the air permeability of the fabrics a, b and c is not obviously increased. Therefore, the polyester fabric prepared by the method has good air permeability. The air permeability of the polyester fabrics d, e and f prepared in comparative examples A-C is also good, which indicates that: the using amount of the emulsifier span 80, the temperature and time of the crosslinking reaction and the using amount of the azodiisobutyronitrile have little influence on the air permeability of the polyester fabric.
Testing of heat retention:
in order to better detect the warmth retention property of the polyester fabrics prepared in the invention, the polyester fabrics a, b, C, d, e and f prepared in the above specific examples 1-3 and comparative examples A-C of the invention and the unfinished polyester fabrics (purchased from Santai weaving in Tanzhou)Factory); the dosage of the selected fabric is 300g/m 2 . The heat retention of the material is tested according to GB/T11048-2008-T 'determination of thermal resistance and wet resistance under the steady state condition of the physiological comfort of the textile'. Before testing, the sample is subjected to pre-humidifying and humidifying treatment according to GB6529-86 'atmospheric environmental standard of constant temperature and humidity chamber'. Humidifying the sample in a constant temperature and humidity box for 24 h, wherein the temperature is (20 +/-2) DEG C, and the humidity is (65 +/-2)%; the sample size was 300mm by 300mm, and the preheating time was 15 minutes. The fabric to be tested is subjected to standard washing by referring to a washing method of a GB/T20944.1-2007 color fastness to washing tester, the heat retention performance of an initial sample and a sample after 10 times of washing are tested, and the test results are shown in Table 2.
TABLE 2 thermal insulation Properties of Terylene fabrics a, b, c, d, e, f and the unfinished Terylene fabrics
As can be seen from Table 2, the Crohn value ranges of the polyester fabrics a, b and c are respectively between 1.08 and 1.18 and are higher than the Crohn value of the non-finished polyester fabric; after 10 times of water washing, the Crohn value of the fabrics a, b and c is not obviously reduced. The higher the cromet value, the better the warmth retention of the fabric. Therefore, the polyester fabric prepared by the invention has good heat preservation performance. The thermal insulation performance of the polyester fabrics d, e and f prepared in the comparative examples A to C is slightly worse than that of the fabrics a, b and C, which shows that: the dosage of the emulsifier span 80, the temperature and time of the crosslinking reaction and the dosage of the azodiisobutyronitrile all have important influence on the heat retention property of the polyester fabric.
Comprehensive analysis shows that the polyester fabric prepared by the invention has better heat preservation performance on the premise of not influencing air permeability.
