Abstract

The invention relates to a method for manufacturing a ceiba heat-preserving material and a ceiba heat-preserving material manufactured by using the same. The method for manufacturing the ceiba heat-preserving material disclosed by the invention comprises the following steps of: 1, pretreating ceiba fibers; 2, opening and mixing ceibas; 3, feeding ceibas; 4, forming a net; 5, stretching; 7, spraying glue; and 8, performing post-treatment, wherein the pretreatment of the ceiba fibers comprises destaticization of ceiba fibers and mechanical premixing at the same time; and the manufactured ceiba heat-preserving material comprises the following fiber raw material components in percentage by mass: 10-30 percent of natural ceiba fiber, 55-80 percent of chemical fiber and regenerated fiber, and 5-15 percent of low-melting-point fiber. Due to the adoption of the method, the problems of easiness in flying, poor net forming property and unstable fiber net quality during treatment of ceibas are solved, and a ceiba heat-preserving material which is soft, comfortable and efficient in preserving heat can be provided.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, and more specifically, relates to a method for manufacturing a kapok thermal insulation material and the kapok thermal insulation material produced therefrom. Background technique [0002] Kapok fiber comes from the fruit of the Kapok family plant, the length of the fiber varies from a few microns to tens of microns, the middle is round and the two ends are slightly pointed, the surface is waxy, and there is almost no curl. The fiber has an inner lumen, and the hollowness is more than >80%. Because kapok fiber has the characteristics of surface hydrophobicity and high hollowness, kapok fiber has been used in life jacket systems, and it has also been reported to be used in marine anti-oil pollution products. [0003] Aspect kapok thermal insulation material, Chinese patent CN100383307C discloses a kind of manufacturing method of kapok batting, selects kapok fiber, low melt...
