Description

Insulation textile material

The invention relates to the field of textiles, in particular to a thermal insulation textile material.

Cold protection is an important indicator of winter clothing comfort. Especially for middle-aged and elderly people or people with localized pain, their waist, shoulders, abdomen, legs or joints are often more vulnerable to cold than other parts of the body, which in turn causes pain in these areas. In addition, as humans are challenged by extreme conditions such as outdoor sports, good clothing that protects against the cold is also required to cope with human survival under extreme conditions, such as cold conditions.

The traditional heat preservation method is usually to control the heat dissipation caused by heat conduction, convection and radiation. For example, thick fabrics or cotton wool thermal insulation materials are used for heat preservation, and some of them also use metal coating materials.

Modern people are increasingly demanding comfort, functionality and aesthetics of clothing. Traditional thermal insulation materials are generally bloated, inconvenient to exercise and lack of beauty. Therefore, research and development of textile materials with good thermal insulation effect and related functional products are of great significance.

The purpose of the present invention is to provide a thermal insulation textile material that can generate heat by using the moisture and heat continuously released by the wearer's body to improve the thermal insulation effect.

In order to achieve the above object, the present invention proposes a thermal insulation textile material, which includes: cellulose fiber 10-70%, low heat capacity polyester yarn 2-50% and outer polyester yarn 10-70% according to the mass percentage content ratio.

Further, in the thermal insulation textile material, the outer polyester yarn is located on the surface layer, the cellulose fiber is located on the middle layer, and the low heat capacity polyester yarn is located on the bottom layer.

Further, in the thermal insulation textile material, the cellulose fibers include viscose, lyocell, cotton, or modal fibers.

Further, in the thermal insulation textile material, the low heat capacity polyester yarn is black charcoal polyester.

Further, in the thermal insulation textile material, the outer layer of polyester yarn shrinks to form an intricate porous fiber structure.

Further, in the thermal insulation textile material, the thermal insulation textile material has a weight ranging from 180 gsm to 360 gsm.

Compared with the prior art, the beneficial effects of the present invention are mainly reflected in: the low heat capacity polyester yarn is located on the bottom layer closer to the wearer's body, can absorb and accumulate the wearer's heat, and then slowly release the heat; cellulose fiber has hygroscopic heat generation Function, it can absorb the moisture generated by the wearer to generate heat. In addition, the outer polyester yarn can shrink to produce a porous structure to form an air channel, so a static air layer is formed as an isolation layer, which can isolate the wearer from the outside cold environment. , So as to maintain the temperature.

The following will describe the thermal insulation textile material of the present invention in more detail with reference to a schematic diagram, in which preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention . Therefore, the following description should be understood as a broad understanding of those skilled in the art, and not as a limitation of the present invention.

The invention proposes a thermal insulation textile material, which includes: cellulose fiber 10-70%, low heat capacity polyester yarn 2-50% and outer polyester yarn 10-70% according to the mass percentage content; wherein, the outer polyester yarn is located at In the surface layer, the cellulose fiber is located in the middle layer, and the low heat capacity polyester yarn is located in the bottom layer.

Specifically, the cellulose fibers include fibers such as regenerated cellulose fibers (Rayon), viscose (Viscose) or Lyocell, cotton or modal fibers. The cellulose fiber used can absorb the wearer's moisture and generate heat (Hygroscopic Heat Generation), which can provide better thermal insulation.

The low heat capacity polyester yarn is Black Charcoal Polyester yarn. Because of its low heat capacity, it can absorb and accumulate the wearer's own heat, and can slowly release the heat, and can also produce a better thermal insulation effect.

The outer layer of polyester yarn can form an intricate porous fiber structure after shrinking. A static air layer can be formed in the porous channel fiber structure, thereby acting as an isolation layer, which can isolate the outside cold air to a certain degree, and then produce a better thermal insulation effect.

In addition, because the outer polyester yarn has good shrinkage, it can shrink to produce a porous structure, forming an air channel, which can be applied to more demanding clothing preparation fields, and is more comfortable and suitable for human wear.

In this embodiment, the weight of the thermal insulation textile material ranges from 180 gsm to 360 gsm, preferably, the weight is 270 gsm.

The thermal insulation textile material proposed in this embodiment is a very efficient self-heating material, which is very suitable for cold environments. It can release heat continuously according to the moisture and heat generated by the wearer. The unique combination of silk thread and the gap with the wearer can provide the wearer with a warm and comfortable wearing environment.

The thermal insulation textile material proposed in this embodiment not only has the effect of absorbing heat and generating heat, but also has good insulation characteristics, and also does not need to add any chemical reagents or coatings. The above functions are completely achieved by virtue of the properties of the thread itself. The material itself has a flexible feel, which is very helpful for preparing different types of clothing. According to needs, it can also be made into materials with functions such as waterproof, antibacterial and antimicrobial.

The thermal insulation textile material proposed in this embodiment can increase the temperature by more than 5 degrees Celsius according to the detection average, and has a good thermal insulation and temperature increase effect. The specific test results are as follows:

Please refer to Figure 1. Figure 1 is the effect diagram of the hygroscopic heat generation test. According to the GAP test method S1050, the test is to compare the temperature rise of the test sample under control. When the relative humidity increases from 10% to 90% and the temperature of the test chamber is maintained at At 20 degrees Celsius, the test results show that the temperature rise brought by the thermal insulation textile material far exceeds the baseline by 2 degrees Celsius, and it can still stabilize above 5 degrees Celsius after 3 or 20 washings.

Please refer to FIG. 2, which is the effect diagram of the dry heat production test. Since the material used on the surface of the thermal insulation textile material provided in this embodiment can generate infrared waves (IR waves) under a heat source, this function can enhance the thermal insulation textile material by the human body. The heat generated. It can be seen from Fig. 2 that the results of the dry heat production test: use a 150W halogen headlight equidistant (15cm) to heat the submitted test sample (this product) and the reference sample (100% polyester fabric), after one minute of heating It can be seen that the temperature of the test sample is significantly higher than that of the reference sample.
