Problems solved by technology

[0004] The spray-bonded cotton and silk-like cotton currently on the market are mainly made of coarse denier polyester ordinary staple fibers (such as 2.2dtex, 3.3dtex, 5.5dtex polyester ordinary staple fibers) and three-dimensional crimped fibers (such as 6.7dtex, 7.8dtex) Three-dimensional curly fiber), although its bulkiness and resilience are better, but the space between the fibers is relatively large. When there is wind and the temperature difference between the inside and outside is large, the air convection in the warm-keeping wadding is more serious, so the warmth-keeping effect is still to be determined. improve
In addition, because polyester has very good rigidity and uses coarse denier fibers, the thermal in

Abstract

The invention discloses a heat insulation flocculus which is made from the following fiber: 10-64wt/% of fine denier fiber and/or superfine denier fiber, 31-80wt/% of hollow fiber and 5-30wt/% of tacky fiber. The heat insulation flocculus is manufactured by the following method: shredding and mixing various fiber raw materials; carding and spreading webs to form a fiber web; then performing random drafting on the fiber web to cause the fiber web to form a 3D network crossed structure; heating and baking the fiber web to cause at least the surface layer of the tacky fiber to be melted, and binding the surrounding fiber of the fiber web. The use of the fine denier fiber greatly increases the content of still air in the heat insulation flocculus, reduces heat conduction, can divide the space in the heat insulation flocculus into smaller spaces, and prevents or reduces air convection, thus improving the heat insulation performance of the insulation flocculus; the hollow fiber can improve bulkiness and compression resilience of the heat insulation flocculus; and the random drafting causes the bulkiness and the compression resilience of the heat insulation flocculus to be higher.

Description

technical field [0001] The present invention relates to a thermal insulation batt made of fibers and a manufacturing method of the thermal insulation batt. Background technique [0002] Warm flakes are the main accessories of clothing, mainly to prevent cold and keep warm, and their texture is usually relatively soft. The materials used in traditional thermal insulation sheets include natural thermal insulation materials such as cotton wool, cashmere and down. Among these natural thermal insulation materials, down is the best thermal insulation material, followed by cashmere, and then wool. Medium warmth is the worst. Most natural thermal insulation materials have a high moisture absorption rate and poor resilience. After a period of use, the thermal insulation performance of thermal insulation wadding will be greatly reduced. Therefore, natural thermal insulation materials are constantly being eliminated during the development of thermal insulation wadding. Among natural ...
