Embodiment 1
[0030] Prepare a kind of antibacterial polyester nylon composite superfine fiber:
[0031] 1) Making antibacterial masterbatch: blend CuO powder and polyester chips, and prepare antibacterial masterbatch by conventional extrusion and pelletizing methods, wherein the antibacterial masterbatch contains 20% CuO particles and 80% polyester, The particle size of the antibacterial masterbatch is about 3-5mm;
[0032] 2) Drying: take raw materials polyamide-6 or polyamide-66, polyester chips, antibacterial masterbatch and dry;
[0033] Among them, the intrinsic viscosity of polyester chips is 0.67dl / g, which comes from Shanghai Lianji Company, brand: semi-dull; among them, the intrinsic viscosity of polyamide-6 is 2.7dl / g, which comes from BASF company, brand: semi-dull
[0034] 3) melting;

Abstract
The invention relates to an antibacterial polyester and polyamide composite superfine fiber and a preparation method thereof; the cross-section of each monofilament in the antibacterial polyester and polyamide composite superfine fiber is round or basically round, wherein, the *-shaped part which passes through the cross section in the radial direction is polyamide fiber and the residual part completely divided by the polyamide fiber is polyester fiber, wherein, the polyester fiber is PET fiber which is mixed and melted with CuO grains or AgO grains; furthermore, the dispersed phase dimension of the CuO grains or the AgO grains is 200nm to 600nm and the CuO grains or the AgO grains are uniformly dispersed inside the fiber and have an antibacterial function after being dissolved out partly. The antibacterial polyester and polyamide composite superfine fiber and the preparation method successfully solve the problems of decollation and splitting failure and overcome the technical bottleneck that the antibacterial composite superfine fiber can not be prepared in the prior art.
Description
technical field [0001] The invention relates to a polyester-nylon composite superfine fiber used for home textile products and a preparation method thereof. Background technique [0002] With the continuous improvement of people's material and cultural living standards, people have higher and higher requirements for fiber products such as clothing and home textiles. They are not only beautiful and durable, but also pay more and more attention to comfort and health care. Textile products made of various differentiated fibers with these functions are more and more favored by consumers, among which ultrafine fibers have developed rapidly in recent years. [0003] At present, the production methods of ultrafine fibers include: direct spinning, compound spinning, blend spinning, jet spinning, flash spinning, centrifugal spinning and other methods. The method of composite spinning is generally used in China now, and the technology of this composite spinning is relatively mature. ...
