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 good rigidity and uses thicker fibers, the thermal insulation flakes produced are relatively hard to the touch, which does not meet people's needs for soft and comfortable thermal insulation flakes.

Abstract

The invention relates to insulation flocculus which is made by 20-80 percent by weight of superfine denier fiber, 10-70 percent by weight of fine denier fiber, 5-30 wt% of tacky fiber and 0-5 wt% of bond. The insulation flocculus is made by adopting the following steps of: loosening and mixing the fiber raw materials; carding and lapping to form a fiber web; carrying out disorder traction on the fiber web to enable the fiber web to form a solid meshy across structure; spraying the bond on the two faces of the fiber web; heating and baking the fiber web to enable the tacky fiber to bond the fiber around and to solidify the bond. In the invention, due to the adoption of the superfine denier fiber and the fine denier fiber, heat conduction can be effectively reduced, cross ventilation in the space can be prevented or reduced, and the insulation property of the insulation flocculus is improved. In addition, due to the adoption of the tacky fiber and the bond, the fill power and the compression resilience of the insulation flocculus can be improved, and the fill power and the compression resilience of the insulation flocculus are higher through disorder traction.

Description

technical field [0001] The invention relates to a heat-preserving wadding made of superfine fibers and a manufacturing method of the heat-preserving wadding. 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 natura...
