Continuous Development Of Fiber Materials Science, High-Performance Fiber More

< p > there are many kinds of functional fibers, and with the continuous development of fiber materials science, more and more high-performance functional fibers will be developed.

Functional fibers can be divided into natural functional fibers, regenerated functional fibers and synthetic functional fibers according to the source of fibers. According to the properties of materials, functional fibers can be classified into organic functional fibers and inorganic functional fibers; according to the application fields of fibers, they can be divided into functional fibers for industrial use, functional fibers for functional materials, functional fibers for home decoration, etc. according to specific functional characteristics, they can be classified into high-strength fibers, high temperature resistant fibers, high moisture absorbing fibers, moisture absorbing and moisture pmitting functional fibers, antibacterial and bactericidal fibers, heat preservation and temperature regulating fibers, flame retardant functional fibers, shape memory intelligent fibers, radiation resistant fibers, conductive and antistatic fibers.

Microfiber fiber is another type of functional fiber, which consists of suede, peach skin, new silk type and thin wool type super high density fabric.

< p > different functional fibers have different properties.

High hygroscopic functional fibers and hygroscopic and moisture conductive fibers are two kinds of functional fibers.

The macromolecules of high hygroscopicity functional fibers contain groups that can be combined with water molecules such as hydroxyl and carboxyl groups. Their absorbency is very strong and their ability to release moisture is weak.

The moisture absorption mechanism of hygroscopic and moisture conductive fiber is not exactly the same as that of high hygroscopic functional fiber. Besides the amount of hydrophilic group, the moisture absorption mechanism mainly depends on the "core absorption" effect of the hollow fiber with surface micropores.

< p > when spinning, different functional synthetic fiber varieties can be obtained by adding functional ultrafine powders; adding blended ceramic superfine powder can produce far-infrared functional synthetic fibers; adding Cu, Ag and other metal elements and other compounds or other antimicrobial agents can produce synthetic fibers with antibacterial function; adding blended titanium dioxide and Zinc Oxide can produce synthetic fibers with UV protection function; adding different color changing ultrafine powders can obtain various synthetic fibers with discoloration function; adding blended flame retardant materials can obtain synthetic fibers with flame retardant function; and adding blending conductive powder such as carbon black can obtain synthetic fibers with conductive function.
