A kind of thermal insulation wadding with air lock function and preparation method thereof

Abstract

The invention discloses a thermal insulation wadding with an air lock function and a preparation method thereof. The method for preparing a thermal insulation wadding with an air lock function comprises the following steps: uniformly mixing viscose fibers, ES fibers and three-dimensional crimped hollow polyester fibers The fiber raw material is obtained; then the fiber raw material is opened twice and then sent to a carding machine for carding to form fiber web fibers; the fiber web fibers are rearranged with messy sticks, so that the fiber web fibers form a criss-cross structure; the processed The fibers of the fiber web are sent to the laminating machine for laying, and the fiber flakes are obtained; the fiber flakes are pre-punched and needled, and hydrogen peroxide is sprayed on the surface of the fiber web fibers during the needling process, and then sliced ​​to obtain primary flakes ; The primary wadding is directly sent to the atmospheric pressure plasma surface treatment cleaning machine for surface treatment, and then the thermal wadding is obtained. The present invention overcomes the deficiencies in the prior art, and the thermal wadding has better heat preservation effect and air-permeable effect .

Description

technical field [0001] The invention relates to the technical field of thermal insulation wadding, in particular to a thermal insulation wadding with an air lock function and a preparation method thereof. Background technique [0002] In the traditional sense, thermal insulation materials are mainly used to resist the cold outside air and ensure the basic living needs and physiological functions of the human body. Therefore, they are mainly used in clothing, quilts, sleeping bags and other clothing and home textile fields. However, with the expansion of the scope of human activities and the needs of the environment, thermal insulation materials have begun to be widely used in field tents, military combat uniforms, mountaineering equipment, and automotive, aerospace and other equipment fields. [0003] Warm flakes are flocculent flakes and loose fillers. When the garments are finished, linings must be added (some also have linings), and they must be machine-woven or hand-quil...

AI Technical Summary

Problems solved by technology

Due to the strong thermal insulation effect of the existing thermal insulation wadding, the air permeability is not good, so that the moisture in the clothes cannot be effectively discharged through the thermal insulation wadding to the external environment, and some thermal insulation wadding, such as synthetic The fiber itself has poor hygroscopicity, which makes the moisture inside the clothes accumulate, making warm clothes uncomfortable to wear; and in order to improve the ventilation effect, it is necessary to reduce the filling amount of the thermal insulation wadding, which in turn leads to insufficient thermal insulation wadding. Therefore, there is a need for a thermal insulation floc that can generate air locks inside the clothes and at the same time keep warm and breathable. While improving the thermal insulation effect, it does not reduce the air permeability of the clothes.
