ETD high-shrinkage type elastic double-color fiber and preparation method thereof

Abstract

The invention discloses an ETD high-shrinkage type elastic double-color fiber and a preparation method thereof, and is characterized in that the ETD high-shrinkage type elastic double-color fiber is formed by compositing a first filament body and a second filament body, the ratio of the first filament body to the second filament body is 3:7-7:3, the first filament body is a cationic POY filament,the second filament body is prepared by compositing a component A and a component B, the component A is one of PET, PA and PBT, the component B is one of PET, PA and PBT, and the component A is different from the component B; the preparation method comprises the steps: 1, heating and texturing the first filament body; and 2, stranding the first filament body and the second filament body, to obtainthe high-elasticity double-color fiber. The elastic double-color fiber can be produced, and the production cost can be reduced.

Description

technical field [0001] The present invention relates to a kind of textile field, relate in particular to a kind of ETD high-shrinkage type elastic two-color fiber and preparation method thereof. Background technique [0002] With the progress of society, the chemical fiber industry has developed greatly, and people's requirements for chemical fiber products are getting higher and higher, and chemical fiber products are becoming more and more diverse. However, at present, there are few types of two-color fiber products in the domestic market, and the functions are single and effective. Poor, complex production process. And most two-color fibers do not possess elasticity on the market, and the fiber color with elasticity is single, and scope of application is narrow, can't satisfy the demand of present stage garment fabric market. Contents of the invention [0003] The object of the present invention is to provide a kind of ETD high-shrinkage type elastic two-color fiber an...

[0002] With the progress of society, the chemical fiber industry has developed greatly, and people's requirements for chemical fiber products are getting higher and higher, and chemical fiber products are becoming more and more diverse. However, at present, there are few types of two-color fiber products in the domestic market, and the functions are single and effective. Poor, complex production process

Moreover, most of the two-color fibers on the market do not have elasticity, and the elastic fibers have a single color and a narrow scope of application, which cannot meet the needs of the current clothing fabric market.
