Problems solved by technology

Especially after washing, man-made fibers are easy to clump and entangle with each other, forming tightly aggregated fiber clusters (different from "fiber balls"), resulting in uneven distribution of thermal insulation filling materials and greatly reducing various performances

[0057] Preparation method of thermal insulation filling material

[0058] An embodiment of the present invention also provides a method for preparing the above thermal insulation filling material, which includes: mixing loose fibers and spherical fiber aggregates, wherein the weight ratio of loose fibers to spherical fiber aggregates is (20:80) to (80:20).

[0059] Among them, as a method of the embodiment of the present invention, the spherical fiber assembly and the loose fiber can be prepared first with the raw material fiber, and then the two are mixed, which specifically includes:

[0060] S101, respectively weighing and obtaining raw material fibers for forming loose fibers and spherical fiber aggregates.

[0061] S102. In the CSKS-130 type opener (purchased from Jiangsu Changsheng Company), the raw material fibers are roughly opened and finely opened to obtain loose fibers; the processing parameters are: cylinder diameter: 500mm, open Roller speed: 800r / min; install...

Embodiment

[0084] 1. Raw materials

Abstract

The embodiment of the invention provides an insulating packing material, a preparation method thereof and an insulating product comprising the same, and belongs to the technical field of insulating packing materials. The insulating packing material comprises loose fibers and spherical fiber assemblies. The weight ratio between the loose fibers and the spherical fiber assemblies ranges from 20:80 to 80:20. On the premise of keeping the good heat retention property and fluffiness of the insulating packing material, the water resistance of the insulating packing material is substantially improved.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation filling materials, and in particular relates to a thermal insulation filling material, a preparation method thereof, and a thermal insulation product. Background technique [0002] In clothing, quilts, etc., it is often necessary to fill with thermal insulation filling materials to improve the warmth retention of the product. This thermal insulation filling material is mostly fluffy and loose materials composed of fine fibers, which are mainly divided into two types: natural and artificial. [0003] Natural thermal insulation filling materials include duck down, goose down, camel down, cotton and other natural fibers. Natural fibers cannot be produced industrially, the cost is high, and the source is unstable. They are affected by animal diseases and plant production reduction. At the same time, many people are allergic to natural fibers, which have affected the application range of nat...
