Abstract

The invention provides a method for preparing blended fibers with hydroscopic property. The method comprises the following steps: 1. cellulose ester powder is subjected to vacuum drying at a temperature of between 80 and 120 DEG C for 12 to 24 hours, extruded out by a twin-screw rod and diced by a dicing machine to obtain cellulose ester slice; 2. according to the weight percentage, 1 to 20 percent of the cellulose ester slice and 80 to 99 percent of high hydrophobic polymer slice are pre-crystallized respectively and dried for 12 to 24 hours, wherein the drying temperature of the cellulose ester slice is between 100 and 120 DEG C, the the drying temperature of the high hydrophobic polymer is decided according to the variety of the high hydrophobic polymer, and the slices are blended and dried in a vacuum rotary drum oven for 1 to 2 hours, the drying temperature is between 100 and 200 DEG C, and the mixing slice is prepared; and 3. the mixing slice passes through the general melt spinning equipment to prepare the blended fibers with good hydroscopic property. The method has the advantages of good hydroscopic property of the hydrophobic fiber, simple and convenient process, environmental protection, no modification to the production equipment and the like.

Description

technical field [0001] The invention relates to a method for preparing hygroscopic blended fibers, in particular blending and spinning cellulose ester and hydrophobic high polymer to improve the hygroscopicity of the hydrophobic fibers. Background technique [0002] With the development of science and technology and the continuous improvement of living standards, people have put forward new requirements for synthetic fiber fabrics: wearing comfort, can quickly absorb sweat and reduce the relative humidity between the fabric and the skin under hot and humid conditions, eliminate The stuffiness that synthetic fibers usually produce. Since most synthetic fibers are hydrophobic fibers with poor hygroscopicity, their production and application are greatly restricted. For example, polyester fiber, which occupies an important position in synthetic fibers, is favored by people for its advantages of high strength, good wear resistance, good resilience, easy washing, quick drying, an...
