Description

A kind of anti-ultraviolet, antibacterial and moisture-conducting and quick-drying blended yarn and its preparation method and application

technical field

The invention relates to a multifunctional yarn with anti-ultraviolet, antibacterial, moisture-conducting and quick-drying properties, a preparation method and application thereof.

Background technique

Since summer is a season of strong solar radiation, high temperature, and a lot of sweating, clothing, as a barrier between the human body and the outside world, should be able to effectively protect the human body. With the change of consumption concepts and health concepts, people have more and more updated requirements for summer clothing. For this reason, clothing with health care and comfort functions has begun to be favored.

Clothing is made of yarn, and yarn is made of fibers. Among all kinds of clothing fibers, chemical fibers have been widely used because of their excellent spinnability, resource availability and consumer acceptance. However, due to the dense molecular structure and lack of hygroscopic groups of most chemical fibers, they are inferior to natural fibers in terms of wearing comfort and aesthetics, which limits their wider application. Therefore, for chemical fibers, mainly polyester comfort research has become the focus of attention.

Current methods to improve the comfort and functionality of synthetic yarns and fabrics include:

1) Moisture-conducting and quick-drying fabrics can be obtained by spinning and weaving modified polyester staple fibers (filaments) or polyester staple fibers (filaments) with special-shaped cross-sections, which can improve the wet comfort of the fabrics;

2) Antibacterial, moisture-conducting and quick-drying fabrics are obtained by spinning and weaving special-shaped cross-section staple fibers and antibacterial short fibers or special-shaped cross-section filaments and antibacterial filaments, so as to improve the wet comfort and hygiene of the fabrics;

3) The anti-ultraviolet and moisture-conducting quick-drying fabric is obtained by spinning and weaving the filament yarn with special-shaped cross-section added with ultraviolet shielding agent, so as to improve the wet comfort and protection of the fabric;

4) The fabric is finished with a moisture-absorbing and sweat-wicking agent, but there is a problem of timeliness.

US6399705, US6322886, US6303739 and US6454982 have all introduced the preparation method of polyethylene glycol modified polyester filament and the application on yarn and fabric, this modified polyester fiber fabric has hygroscopicity, wicking property, fast Dryness, flame retardancy, antistatic and soft touch are much superior to those of traditional polyester fabrics.

US5888914 introduced the use of water-repellent fiber and hydrophilic fiber blending to obtain comfortable yarns and fabrics with higher hydrophilicity than pure spinning of water-repellent fiber.

US6439270 introduces a warp woven fabric that is lightweight, quick-drying, and unidirectionally absorbs and dissipates sweat. By using polypropylene (PP) and polyvinyl chloride (PVC) with good moisture permeability as warp or weft, the weft is distributed in straight strips, and the warp The undulations shuttle through the weft yarns, so the warp yarns make point contact with the skin to absorb sweat, and then transfer to the weft yarns. The sweat flows in one direction on the fabric and spreads and dries quickly, making the human body feel dry and comfortable.

CN1560341A introduces a new type of moisture-conducting and air-permeable yarn obtained by blending fibers of different types, different finenesses, and different lengths. The fabric woven with this yarn has the function of moisture-conducting and quick-drying.

CN1563533A introduces a new type of moisture-conducting yarn obtained by blending fibers of different types, different finenesses, and different mixing ratios. The fabric woven with this yarn has the function of moisture-conducting, quick-drying, and comfortable contact.

Most of the above-mentioned patents are obtained by introducing the comfort function of polyester fiber fabrics, while the introduction of multifunctional yarns is rarely reported.

。The so-called moisture-wicking fibers mostly refer to the physical modification of synthetic fibers to make hydrophobic fibers into hydrophilic fibers. When spinning, special-shaped spinneret holes are used to produce hollow or special-shaped cross-section fibers, forming many grooves on the surface of the fibers, or forming hollows with many holes on the hollow walls. In this way, moisture can be absorbed and conducted through the capillary effect. Synthetic fibers basically absorb free water, which is lost quickly. As long as it can be diffused quickly, it can be evaporated, so that it has the function of moisture-wicking and quick-drying. The present invention adopts the "ten" cross-section moisture-conducting fiber, and the longitudinal four grooves on its surface are conducive to the conduction of moisture, such as the coolbest product produced by Yizheng Chemical Fiber Co., Ltd.

纤维。Said antibacterial fiber refers to the addition of an antibacterial agent called Triclosan or nano silver ions in the spinning stock solution. Antibacterial agents can effectively inhibit the reproduction of many bacteria, such as: Staphylococcus aureus, Salmonella typhimurium, Escherichia coli and Klebsiella pneumoniae. The antibacterial agent is distributed in the fiber in the form of particles, not scattered in the entire structure of the fiber in a molecular form, so the antibacterial agent particles can slowly dissolve the antibacterial agent to the surface of the fiber like a warehouse, and exert an antibacterial effect. Said antibacterial fiber can adopt commercially available product, as the nano-silver series fiber that China Academy of Textile Sciences develops, the texcare nano-silver antibacterial fiber that Taiwan Haojie Co., Ltd. produces, or the Amicor of British Courtaulds company

fiber.

等。Said anti-ultraviolet fiber refers to the fiber with anti-ultraviolet damage ability or the fiber containing anti-ultraviolet additive. For example, acrylic fiber is an excellent anti-ultraviolet fiber; while nylon has poor anti-ultraviolet ability, it is necessary to add a small amount of additives (such as manganese salt and hypophosphorous acid, manganese borate, aluminum silicate and manganese salt-cerium) to the polymer for making nylon. salt mixture, etc.), that can make anti-ultraviolet nylon. UV-resistant polyester is made by incorporating ceramic UV blocking agents into polyester. The present invention uses nano-scale titanium-based or zinc-based powders as ultraviolet shielding factors and adds them into polyester stock solution for spinning. The light-heat aging resistance of the fabric woven by this fiber is greatly improved, and it has the function of sun protection and cooling, thus Reduce the chance of getting skin cancer. Commercially available products can be used, such as the anti-ultraviolet fiber developed by Shanghai Jiaotong University, and cooltouch produced by Taiwan Xinguang Synthetic Fiber Co., Ltd.
