[0050] Preparation method of thermal insulation filling material
[0051] The present invention also provides a preparation method of the above-mentioned thermal insulation filling material, which includes:
[0052] The elastic fibers are spheronized to form spherical fiber aggregates.
[0053] That is to say, the raw materialelastic fiber can be subjected to conventional ball forming process (of course, it can also be opened, etc.), so as to form a spherical fiber aggregate to obtain the above thermal insulation filling material.
[0054] Insulation products
[0055] The invention provides a thermal insulation product, which comprises:
[0057] The above-mentioned thermal insulation filling material arranged in the closed internal space defined by the covering body.
[0058] That is to say, the above thermal insulation filling materials can be arranged in a closed covering structure, so as to form a practical...
Embodiment 1
[0087] Take 5kg of elastic fiber 1, and after fully loosening, use a ball forming machine (HJZZM-100 pearl cotton machine, purchased from Kunshan Haijin Machinery Co., Ltd.) to form spherical fiber aggregates with a particle size of 2 to 20 mm, and make such figure 1 The thermal insulation filling material of Example 1 is shown.
Embodiment 2
[0089] Get 5kg of elastic fiber 2, and after fully loosening it, use a ball forming machine (HJZZM-100 pearl cotton machine, purchased from Kunshan Haijin Machinery Co., Ltd.) to form spherical fiber aggregates with a particle size of 2 to 20 mm to obtain Example 2 insulation filling material.

Abstract
The invention provides a thermal insulation filling material, a preparation method thereof, and a thermal insulation product, belonging to the technical field of thermal insulationfilling materials, which can at least partially solve the problems of poor durability such as washing resistance and compression resilience of existing thermal insulation filling materials. The thermal insulation filling material of the present invention comprises: a spherical fiberassembly composed of elastic fibers, wherein the elastic fibers have an elastic elongation rate of 80-300% and an elastic recovery rate of 85-99%.
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] Thermal insulation filling material is a loose material composed of a large number of fine fibers, which can be filled into clothing, quilts, etc. to play a role in thermal insulation (such as keeping warm). Since the fine fibers of the thermal insulation filling material can move relative to each other under force, the overall shape of the product can also change with the user's patting and pressing, which fits the user's body better and improves the user experience. [0003] Traditional thermal insulation filling materials mainly use natural down such as duck down and goose down. The physical structure of natural down determines its good bulkiness, compression resilience, heat retention and other propertie...
