Abstract

The invention belongs to the field of spinning, particularly to a new type modified chopped fiber of permanent porous high-moisture-absorption quick-drying terylene and a preparation method thereof. The modified chopped fiber of terylene provided by the invention is the modified chopped fiber of terylene which can be dyed through the cationic dye under normal pressure and temperature, wherein thesurface and interior of the cylindrical fiber both have irregular permanent porous structures; the pores are mutually communicated; the chopped fiber has a specific raw material composition and proportion; and the irregular permanent porous structures are formed by spinning under the condition of adding no pore-forming agent and have the permanent high-moisture-absorption quick-drying function byutilizing the core absorption effect of inside capillary tubes. The chopped fiber is shaped at 150-170 DEC, so the chopped fiber is fit for blending, white spinning and color spinning, and the defects of heat migration, color fastness, sublimation fastness, and the like, caused by high-temperature shaping in the process of normal terylene color spinning are avoided. The cationic dye under normal pressure and temperature is energy-saving and low-carbon. Other multifunctional fibers can be prepared by using the fiber as carrier and adding functional micron powder and sub-nanometer powder materials.

Description

technical field [0001] The invention belongs to the field of spinning, and relates to a functional chemical fiber product, in particular to a novel permanent microporous, highly moisture-absorbing and quick-drying polyester modified short fiber and a preparation method thereof. Background technique [0002] Moisture absorption and quick-drying technology is an important means to improve the wearing comfort of polyester-containing clothing. Represented by DuPont in the United States and some Taiwanese companies, they have developed and produced physically modified moisture-absorbing and sweat-wicking polyester staple fibers with a cross-section of +, such as DuPont’s COOLMAX , Taiwan's COOLPLUS, etc., after several years of product development practice, clothing fabric manufacturers have gradually discovered that: the moisture absorption and perspiration effect of +-shaped polyester staple fiber is very general, if the fabric or finished clothing is not supplemented with hydro...
