Abstract

The invention discloses a cool fiber / hemp composite summer sleeping mat and a manufacture method thereof. The composite summer sleeping mat is a double-faced fabric structure, cool colored filament fiber yarns and hemp blended yarns are arranged on the front surface of the composite summer sleeping mat, and hemp blending yarns are arranged on the bottom surface of the composite summer sleeping mat. The cool colored filament fiber yarns are of a leather-core structure, the leather layer is blend of at least one of polymer, a jade powder body and dye, and the core layer is the polymer which is polyamide or polyester. The hemp blending yarns are formed by blending at least one of hemp fibers, viscose fibers and cotton fibers, viscose fibers and bamboo fibers. The cool colored filament fiber yarns arranged on the front surface of the cool fiber / hemp composite summer sleeping mat of the double layer structure serve as the main body, and the hemp blending fiber yarns are arranged on the bottom surface, so that cool and comfortable performance and moisture absorption performance of the summer sleeping mat are well combined when contacted with skin of a human body, and simultaneously the summer sleeping mat has antimicrobial performance, requires no dyeing during the dyeing and finishing process and produces no dyeing waste water.

Description

technical field [0001] The invention relates to a cooling fiber / hemp composite summer mat and a preparation method thereof. Background technique [0002] Summer mat is a summer bedding, usually made of grass and bamboo materials. The preparation method is to use flexible materials (such as yarn or thread) to weave materials in the form of grass, bamboo chopsticks or bamboo strips. . Bamboo summer mat has the advantages of high thermal conductivity and smooth surface, but has the disadvantages of high hardness, discomfort, and poor sweat absorption performance. Although the grass mat is soft and comfortable, its strength after moisture absorption is low and its service life is short. Regardless of the straw mat or bamboo mat, due to the limitation of its folding method, it takes up a lot of space for storage and storage. Hemp fiber not only has good moisture absorption and quick-drying effect, but also has good antibacterial properties and high wet strength; hemp fabric is...
