[0088] Preparation method of thermal insulation flake material

[0089] The present invention also provides a method for preparing the above-mentioned thermal insulation flake material, which includes:

[0090] Stacking multi-layer fiber single nets;

[0091] Heat setting treatment is performed on the stacked multi-layer fiber monowebs.

[0092] That is to say, fiber single nets can be formed by carding first, and then layers of multi-layer fiber single nets are laid together by laying (such as cross-laying), and then these stacked fiber single nets are heat-set. (For example, treat at a temperature of 120-180°C for 5-15 minutes), so that it can form a thermal insulation flake material.

[0093] Insulation products

[0094] The invention provides a thermal insulation product, which comprises:

[0095] an enclosure defining an enclosed interior space;

[0096] The above-mentioned thermal insulation flake material arranged in the closed inner space defined by the coveri...

Embodiment 1

[0130] Using 3kg of cellulose fiber 1, 3kg of first-type fiber 1, 2kg of first-type fiber 2, and 2kg of low-melting point elastic fiber 1 as raw materials, use Jiangsu Yingyang Nonwoven Machinery scx26 type spray-bonded cotton production line, by mixing -The process of opening-carding-cross-lapping forms a multi-layer network structure with a grammage of 100gsm, and then heat-setting at 145°C for 6-9 minutes to keep the wadding material.

Embodiment 2

[0132] Using 4kg of cellulose fiber 1, 2kg of first-type fiber 3, 1.5kg of first-type fiber 4, and 2.5kg of low-melting point elastic fiber 2 as raw materials, Jiangsu Yingyang Nonwoven Machinery scx26 spray-bonded cotton production line was used. Through the process of mixing-opening-carding-cross-lapping, a multi-layer network structure with a grammage of 100gsm is formed, and then heat-set at 145°C for 6-9 minutes to keep the flake material.

Abstract

The invention provides an insulation flaked material and a preparation method and an insulation product thereof, and belongs to the technical field of insulation flaked materials, the problem at leastcan be partially solved that the existing insulation flaked material is difficult to obtain good softness, resilience, filling power and heat retaining property simultaneously. The insulation flakedmaterial comprises a multilayered and heat-set fiber single-net, wherein each layer of fiber single-net is prepared from, by weight, 10-50% of cellulose fiber, 5-25% of low-melting elastic fiber, and25-85% first class fiber, wherein the cellulose fiber which does not belong to the low-melting elastic fiber, the low-melting elastic fiber which does not belong to the cellulose fiber, and the firstclass fiber which does not belong to the cellulose fiber and also does not belong to the low-melting elastic fiber.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation wadding materials, and in particular relates to a thermal insulation product, a preparation method thereof, and a thermal insulation product. Background technique [0002] The thermal insulation flake material is a sheet or layered thermal insulation material, which can be filled in clothes, shoes, gloves, sleeping bags, etc. to keep warm (such as keep warm). In many cases (such as baby bedding or clothing materials), it is desired that the thermal insulation flake material has a softer touch to improve wearing comfort. [0003] Generally speaking, in order to make the insulation wadding material feel soft, it is necessary to use finer fibers in it, but the softness of the insulation wadding material is contradictory to its resilience and bulkiness, that is, the increase of softness will reduce the thermal insulation performance. The batting material's resiliency, loft, and ultimately ...
