Embodiment

[0019] This example is a high-resilience thermal non-woven fabric, which uses hollow fibers and special-shaped fibers as base materials, and uses environmentally friendly resins with extremely low formaldehyde content and low glass transition temperature as adhesives. It has light weight, good bulkiness, It has the characteristics of high resilience, softness and warmth retention. The products of this embodiment are generally more used in the cuffs of jackets and access control.

[0020] This embodiment is a high resilience thermal non-woven fabric, and its preparation process comprises the following steps:

[0021] 1) Select the base material: select hollow fiber and special-shaped fiber as the base material, and the hollow fiber contains 15-25% of 3D crimped fiber, 65-75% of 1.5D crimped fiber and 5-15% of special-shaped fiber;

[0022] 2) Substrate treatment: it includes,

[0023] A. Substrate mixing: put the whole package of the hollow fiber and the shaped fiber into the...

Abstract

The invention discloses a high-rebound-elasticity warm non-woven fabric. A preparation process of the high-rebound-elasticity warm non-woven fabric comprises the following steps that (1) a base material is selected, specifically, hollow fibers and a profile fiber are selected as the base material which comprises 15-25% of a 3D crimped fiber, 65-75% of a 1.5D crimped fiber and 5-15% of the profile fiber; (2) the base material is treated; (3) web forming is conducted through carding, specifically, the fibers are uniformly subjected to carding to form a cotton web; (4) impregnation and resin spraying are conducted, specifically, the cotton web is fed into an impregnation machine, a softening agent and a penetrating agent are added into the impregnation machine, and acrylic-based resin subjected to foaming treatment is sprayed on the surface of the cotton web; and (5) drying and forming are conducted, specifically, heating and drying are carried out, the cotton web and the acrylic-based resin are subjected to bridge formation. The high-rebound-elasticity warm non-woven fabric has the characteristics of being small in mass, good in fill power, high in rebound elasticity, good in softness and warmth, and the like.

Description

【Technical field】 [0001] The invention relates to a non-woven fabric, in particular to a heat-retaining non-woven fabric with high resilience. 【Background technique】 [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics. In the future, clothing fabrics will develop in the direction of comfort and health, high resilience and Functional textiles related to warmth will become a major trend in future market consumption. In the prior art, the patent application number is 201110172621.4, which discloses a fast high-resilience warm-keeping flake and its preparation method. Although it realizes the function of rebounding and keeping warm, its quality is relatively heavy, and the rebounding effect is not ideal. [0003] Therefore, be necessary to provide a kind of new high resilience thermal non-woven fabric to solve the above problems. 【Cont...
