Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem of low infrared transmittance of cool fabrics in the prior art, and provide a cool fabric with high human body infrared transmittance and a preparation method thereof. In the preparation process, a thin and transparent plain weave fabric is selected as the base material. Cloth, polyethylene with very high permeability to human body heat radiation is selected as the filling material, and the mixture of polyethylene and thinner fills the pores between the warp and weft tows of the base fabric and does not penetrate through controlling the appropriate pressure and molding time. into the inside of the tow, and then remove the diluent by extraction to prepare connected pores, so that the composite becomes opaque and has breathable and sweat-wicking properties, and finally obtains high permeability to human infrared heat radiation, opaque to visible light, and wear resistance. Good, cool fabric with excellent mechanical properties and good breathable and sweat-wicking properties

Abstract

The invention relates to a cool fabric with relatively high human body infrared permeability, and a preparation method thereof. According to the preparation method, polyethylene and a diluent are mixed and are subjected to melting; the surface of a base cloth is coated with an obtained melted mixture; laminating is carried out at 140 to 170 DEG C under 0.2 to 0.8MPa; cooling is carried out; the diluent is removed; drying and setting are carried out; and surface plasma treatment is carried out so as to obtain the cool fabric with relatively high human body infrared permeability. Compared with conventional fabric, the cool fabric with relatively high human body infrared permeability possesses following advantages: dissipation of infrared thermal radicalization generated by human body can be realized preferably, thermal conductivity is high, dissipation of thermal energy generated by human body can be realized in time, blocking capacity on visible light is relatively high, human body is protected from sun light by the cool fabric, the cool fabric also possesses relatively high porosity and a certain degree of hydrophilic performance, so that sweat generated by human body can be discharged quickly, and the cool fabric possesses a certain degree of wearing resistance.

Description

technical field [0001] The invention belongs to the field of fabric fabrics, and relates to a cool fabric with high human body infrared transmittance and a preparation method thereof. Background technique [0002] For a long time, how to keep comfortable and cool in hot summer has been the subject of people's tireless research. The traditional method is to provide people with a comfortable and cool living experience by building heat-insulated buildings and installing cooling facilities such as air conditioners in the room. However, these measures It is costly and time-consuming, but also causes huge waste of energy. At the same time, people are also tirelessly studying the cool fabrics worn in summer, such as by preparing light, breathable and transparent chiffon fabrics to bring a cool experience in summer. This light, transparent and transparent fabric can make the heat of the human body well through When going out, the outside light can also shine on the human body throu...
