Description

Technical Field

[0001] The invention relates to the field of textile fabrics, in particular to hollow polyester fiber thermal insulation fabrics. Background Art

[0002] Polyester fiber thermal insulation fabrics are widely used, and their excellent tensile resistance makes them have a long service life. Polyester, also known as polyester fiber, is a man-made fiber and one of the common materials for making clothes. It appeared in the middle of the last century and was widely used in the clothing industry as a new synthetic fiber. Polyester is a kind of chemical fiber, belonging to the polyester family, and has the characteristics of easy degradation in the natural environment. It has abundant raw material sources and simple production process, so the cost is relatively low. Due to its wear resistance, wrinkle resistance, and easy cleaning, polyester has been widely used in clothing manufacturing.

[0003] The thermal insulation performance of polyester fabric is closely related to the thickness and density of its fiber. Generally speaking, the thicker the fiber and the higher the density, the better the thermal insulation performance. In addition, the tighter the texture of the fabric and the smaller the air layer, the better the thermal insulation performance. In summary, a single polyester fabric has thermal insulation performance, but the specific thermal insulation effect depends on factors such as the thickness and density of the fiber, the structure of the fabric, and the amount of filling in the clothing. In many cases, in order to achieve the comprehensive performance of the fabric, composite fabrics are used to enhance its performance.

[0004] The existing Chinese patent with publication number CN113502658A discloses a thermal polyester fabric and a preparation method thereof. The thermal polyester fabric can be prepared by the following preparation method: first, zirconium nitrate pentahydrate, anhydrous ethanol and other raw materials are used to prepare zirconium sol; second, under plasma conditions, the zirconium sol reacts with nanographene to obtain a reaction liquid; finally, the polyester fabric is reacted and finished in the reaction liquid to obtain the thermal polyester fabric.
