Description

Technical Field

[0001] The invention relates to the technical field of polyester fabrics, and in particular to a cool and smooth fabric and a preparation method thereof. Background Art

[0002] Currently, there are significant technical bottlenecks in the field of functional fabrics for summer: traditional cooling fabrics rely on a single mineral additive, which lacks long-lasting cooling effect and poor thermal conductivity; antibacterial fibers mostly use silver ion coating or physical blending process, resulting in low wash resistance and risk of skin contact; silicone oil finishing agents are often used for softening treatment, which can improve smoothness but are easy to migrate and cause yellowing. Excessive use will block the fiber pores and reduce the air permeability and moisture permeability.

[0003] Existing technologies struggle to achieve the synergistic integration of cooling, antibacterial, and soft properties. They often rely on multi-layer composite structures, resulting in heavy fabrics and unbalanced wearability. Therefore, developing a new fabric that combines cooling, antibacterial, and soft properties has become a pressing technical challenge in this field. Summary of the Invention

[0004] Technical problems solved

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a cool and smooth fabric and a preparation method thereof, which can effectively solve the problem that the polyester fabrics of the prior art are difficult to achieve the synergistic integration of cooling, antibacterial and soft functions.

[0029] Beneficial effects

[0030] The present invention provides an ice-cool and smooth fabric and its preparation method. Compared with the existing well-known technologies, the present invention has the following beneficial effects:

[0031] The present invention prepares antibacterial modified polyester fibers by using a composite modification process of nano-zinc oxide and silane coupling agent KH-560, which can form a chemical bond type loading structure of antibacterial components on the fiber surface, thus far exceeding the wash resistance of ordinary antibacterial fibers. At the same time, the slow-release mechanism of nano-zinc oxide can avoid direct skin contact, with both safety and persistence. Secondly, the cool-sensation modified polyester fibers achieve a dual cooling mechanism through the microencapsulation technology of peppermint essential oil and the compounding of high thermal conductivity minerals. The microcapsules slowly release peppermint essential oil to provide contact cool-sensation, and aluminum nitride powder and jade powder build a fast heat conduction channel, and the cool-sensation effect can last for a long time. Finally, the softener prepared by compounding hydroxyl-terminated silicone oil and amino silicone oil forms a low surface energy lubricating layer on the fiber surface through molecular chain orientation technology, giving the fabric a smooth touch like silk, which can not only improve the antistatic performance but also avoid the yellowing problem caused by the easy migration of traditional softeners. The fabric prepared in the present invention realizes the three core functions of persistent antibacterial, long-lasting cool-sensation and ultra-smooth softness through the synergistic effect of antibacterial modified polyester fibers, cool-sensation modified polyester fibers and softener immersion liquid, thus solving the technical defects of single function and insufficient comfort of traditional fabrics and significantly improving the wearing experience.
