Description

Anti-ultraviolet knitted fabric and weaving method thereof
Technical Field
The invention relates to the technical field of textile industry, in particular to an ultraviolet-resistant knitted fabric and a weaving method thereof.
Background
Altitude of the plateau area is relatively high, and attenuation effect of the atmosphere on ultraviolet rays is relatively less than that of the plateau area with low altitude; the human smoke is rare, the industrial pollution is avoided, the air is cleaner, and the ultraviolet rays in sunlight are less absorbed; the snow on the plateau has long period and high reflectivity on the snow surface; all three factors enhance the radiation intensity of ultraviolet rays to human bodies. The ultraviolet reflectance at sea is high, sand and sand at sea mutually reflect, the reflection of ultraviolet rays can reach 15-20%, the reflection of seawater is as high as 100% like a mirror, the ultraviolet reflectance of grasslands is less than 5%, grasslands and trees can absorb sunlight for photosynthesis, and asphalt is higher than that of grasslands but not more than 10% in terms of ultraviolet reflectance; the air at sea and the sea is good, and the ultraviolet ray is high in direct incidence; the skin content water rises, so that ultraviolet rays are easier to absorb; these three aspects result in the human body being exposed to very intense ultraviolet radiation at sea and at sea. Ozone absorbs ultraviolet light, so that the ozone layer cavity can cause the increase of ultraviolet radiation; in the ozone layer cavity area, high intensity ultraviolet radiation can pose a great threat to human health.
In recent years, outdoor exercises are popular worldwide, and have become a mainstream exercise form. When people are engaged in mountain climbing, outdoor activities in high altitude areas, maritime play, maritime sports amusement projects and extreme exercises in special areas, the human body is beneficial to health due to the fact that the human body is properly irradiated by ultraviolet rays, and when the human body is subjected to excessive ultraviolet rays in UVB sections, red spots, blisters and burns, even skin cancers, cataracts, immune system disorders and the like are generated; uv light in the UVA range activates melanin in the skin, causing pigmentation, thereby forming black spots. The protection of ultraviolet rays is becoming more and more important for people in outdoor exercises in special areas such as high altitude areas, seasides, ozone layer cavities and the like. With the rapid development of these outdoor exercises and the increasing tendency of outdoor exercise garments, there is a need for ultra-high ultraviolet resistant outdoor exercise garments having ultra-high UPF values and full-band ultraviolet absorption.
Knitted fabrics are classified into warp knitted fabrics and weft knitted fabrics. Weft knitting fabrics generally have good elasticity and extensibility, soft, firm and crease-resistant fabrics, and are easy to wash and dry, but the fabrics are poor in hygroscopicity, stiff and smooth, and easy to break loose, curled, fuzzed, pilled and hooked. Warp knitted fabrics have good air permeability, smoothness, flatness, easy care, ironing, stable structure and difficult detachment, so the warp knitted fabrics are commonly used for manufacturing sportswear, such as swimwear, track and field wear, gymnastics wear, basketball wear and the like, are convenient to stretch in the process of sports and have excellent comfortableness.
With outdoor exercises and the improvement of comfort and functionality, consumers pay more attention to the functionality of the fabric, such as the continuous improvement of performance requirements on ultraviolet resistance, moisture absorption, quick drying, cool feeling, antibacterial and deodorizing of the fabric in the exercise process. For the clothing fabric for outdoor exercises, the ultraviolet-proof and cool feeling functions are particularly emphasized.
Patent document CN103290613a discloses a soft warp knitted fabric, which is woven by warp knitting, and achieves comfort and aesthetic feeling of the knitted fabric, but does not have ultraviolet resistance or sun-screening function.
Patent document CN107868987B discloses a preparation method of an anti-ultraviolet anti-aging insect-resistant fiber, wherein the functional components are complexes formed by lanthanide metals and monobasic organic compounds or complexes formed by polybasic organic compounds, permethrin and deltamethrin. The ultraviolet protection coefficients of the fibers prepared in examples 1-3 were all 50, which still had some room for improvement.
Patent document CN112899801a discloses an anti-ultraviolet aging-resistant synthetic fiber added with rare earth, and a preparation method and application thereof, which not only can keep anti-ultraviolet efficacy for a long time, but also can prevent aging, but also has more complex functional components, namely, a mixture of rare earth oxides such as cerium oxide, yttrium oxide, samarium oxide, gadolinium oxide and the like, inorganic oxides such as silicon dioxide, ferric oxide and the like, benzophenone, salicylic acid, anthranilone, benzhydrol polymerization hindered amine, methylenebis-benzotriazole tetramethylbutylphenol and the like; and the ultraviolet protection coefficient of the fiber prepared in examples 1-3 is 100, which can not well meet the requirements of outdoor sportswear in special areas such as high altitude areas, offshore seasides, ozone layer cavities and the like, and further needs to improve the UPF value and realize full-band ultraviolet absorption.
In the prior art, a method for preparing the textile fabric by adding the ultraviolet resistant auxiliary agent into the master batch is also available. The common anti-ultraviolet auxiliary agent of the master batch comprises organic anti-ultraviolet agents such as benzophenone, salicylate, anthranilate and the like, strongly absorbs ultraviolet light, is well fused with a polymer and has small influence on the mechanical properties of fibers, but has the defects of poor fastness, toxicity of substances generated by molecular chain breakage after absorbing ultraviolet light, and serious influence on human health. The anti-ultraviolet auxiliary agent added in the master batch also comprises inorganic anti-ultraviolet auxiliary agents such as nano titanium dioxide, zinc oxide and the like, can resist high temperature, has good stability, has no irritation to human bodies, basically has no problems of decomposition and the like, but has common absorption and anti-ultraviolet performance in partial wave bands, and can destroy the lasting performance of the anti-ultraviolet after long shielding time.

In some embodiments, the rare earth oxide is nanoscale, nanopowder D 100 Less than 200nm. The nano rare earth oxide can make the knitted fabric have more excellent performance.
In some embodiments, the synthetic fiber carrier is selected from one or more of dacron, nylon, spandex, vinylon, polypropylene, and polyvinyl chloride. Preferably one or more carriers selected from terylene, nylon and spandex.
In some embodiments, the yarn has a thickness of 20d to 40d. The coarser yarn can affect the cloth cover effect of the knitted fabric, so that the finished product effect cannot reach the optimal appearance.
In some embodiments, the textile fiber material is selected from one or more of polyester, nylon, spandex, velcro, polypropylene, and chloraman yarns.
In some embodiments, the knitted fabric is weft knitting using a high gauge high density weaving process.
In some embodiments, the knitted fabric is warp knitted using a high gauge high density weaving process.

The rare earth material has strong capability of capturing hydroxyl, and enhances the moisture absorption and sweat release functions of the cloth and the cool feeling brought by the moisture absorption and sweat release functions. In addition, the spinning performance is good, and the production cost is reduced.
Meanwhile, the function of the ultra-high ultraviolet resistant knitted fabric has great relation with the weaving mode.
