Problems solved by technology

[0002] Fiber is the most commonly used material for clothing fabrics. Its structure and composition play a key role in the comfort of clothes. The processing process of common special-shaped fibers is generally that there are multiple special-shaped spinneret holes on the spinneret plate, and the spinneret The cross-section of the hole corresponds to the cross-section of the fiber, that is, if the triangular special-shaped fiber is to be processed, the spinneret hole is triangular. When the melt is extruded from a small hole, capillary or slit, the diameter or thickness of the extrudate will be significantly larger than the diameter of the small hole, that is, extrusion swelling will appear), the extrusion swelling of polymer melt The general assembly results in a significant

Abstract

The invention discloses a processing technique of profile fiber having functions of moisture absorption and bacteria resistance and a product thereof. The processing technique at least comprises the following steps: matrix polymer is mixed with bacteria resisting additive or bacteria resisting additive master batch; the mixture is heated and pressurized to form high polymer fusant and the high polymer fusant is jetted out through the jetting slit of each spinneret orifice, or a modified polymer mixed with bacteria resisting additive is directly heated and pressurized to form high polymer fusant and the high polymer fusant is jetted out through the jetting slit of each spinneret orifice; and the high polymer fusants jetted out through the spinneret orifices swell owing to Barus effect, and are mutually adhered to form the profile fiber; wherein, the bacteria resisting additive is inorganic additive, organic additive or polymeric additive. The profile fiber processed by adopting the technique of the invention has high degree of profile, good effect of moisture absorption and sweat volatility and excellent bacteria resistance.
