High-elasticity thermal insulation cotton and method for producing same

Abstract

The invention discloses high-elasticity thermal insulation cotton and a method for producing the same. The cotton is prepared by mixing the following raw materials in percentage by weight: 75 to 85 percent of terylene fiber and 15 to 25 percent of low-melting point complex fiber, wherein the titer of the terylene fiber is between 0.6 and 2.75D. The method comprises the following steps that: the two raw materials are put in cotton mixing equipment for even mixing; the mixed raw materials are combed into a planar flake fiber web by a combing machine; the planar flake fiber is paved into a laminar fiber web by a web paving machine; the top surface and the bottom surface of the laminar fiber web are acupunctured by a needle loom to prepare a fiber blanket; the fiber blanket is put in an oven for thermal fusion, taken out and naturally cooled at an ambient temperature of between 10 and 30 DEG C, so that the high-elasticity thermal insulation cotton is obtained. The high-elasticity thermal insulation cotton produced by the method greatly improves the strength of the thermal insulation cotton; and under the condition of equal thickness, the strength of the high-elasticity thermal insulation cotton is 6 to 9 times higher than that of the prior thermal insulation cotton; moreover, the high-elasticity thermal insulation cotton is also excellent in elasticity, permeability and the like.

Description

technical field [0001] The invention relates to chemical fiber warm-keeping cotton, which is a kind of high-elastic warm-keeping cotton and a production method thereof. Background technique [0002] At present, thermal cotton made of chemical fiber materials is widely used in fields such as insoles, shoe linings, and mattresses on the market. This kind of chemical fiber thermal cotton is characterized by low cost, light weight, washable and so on. But its shortcomings are mainly manifested in: no elasticity, the relationship between thickness and strength increases proportionally, it is very difficult to achieve high strength and good air permeability within a certain thickness range, especially in some fields, requiring chemical fiber Thermal insulation cotton is elastic, which cannot be achieved by current thermal insulation cotton and craftsmanship. Contents of the invention [0003] The object of the present invention is to provide a high-elastic thermal insulation c...
