Development and application of high-strength polyester nanofibers

The new ‘Sea/Island’ composite-spinning technology has solved the problem of unstable quality associated with conventional mass-production nanofibers. ‘Sea/island’ composite spinning achieves the high-strength polyester nanofiber based on conjugated (two components) spinning theory. The separation process between sea–islands components is successful with 1000 times faster in alkali solution resolution sea polymer than island polymer. Nanofiber has a very large surface area, absorption, distribution and filtration effect, which are suitable for a variety of applications, including functional sportswear, inner wear, skin-care products, filters, precision grinding cloth, and so on.
