Description

Technical Field

[0001] The utility model belongs to the technical field of knitting, and in particular relates to a high-performance close-gauge warp-knitted outdoor fabric. Background Art

[0002] Knitted fabrics are becoming more and more popular due to their breathable, soft, comfortable and skin-friendly characteristics. Especially as people are increasingly fond of a relaxed and casual lifestyle and the society increasingly advocates outdoor sports such as fitness, new knitted fabrics that are close-fitting, breathable, soft and skin-friendly are increasingly sought after by modern people. This can be seen from the continuous leaps in the sales performance of sports brands. From shoes to tops, pants, and hats, the proportion of sports and leisure continues to expand.

[0003] According to market research, clothing for sports, leisure and fitness is emerging in the clothing field. The fabrics of this type of clothing are completely different from traditional swimwear. They are also spandex elastic fabrics, but they need to have a tight texture and an appearance that resembles woven fabrics. They need to have good elasticity and a smooth feel, and they need to have functions such as moisture absorption, breathability, antibacterial and environmental protection. It is an updated version of traditional elastic fabrics, or a new product that needs to be developed. In addition, long-term outdoor use puts forward new requirements for UV resistance.

[0004] Ultraviolet rays are produced in nature by solar radiation, and the wavelength of the spectrum is 180 to 400 nanometers. According to the different biological effects produced, they are divided into three bands: short-wave ultraviolet rays, medium-wave ultraviolet rays, and long-wave ultraviolet rays. Ultraviolet rays of different wavelengths can be absorbed by different tissues in different layers of the skin. The longer the wavelength, the stronger its penetrating power. Closely related to dermatology are medium-wave ultraviolet rays (UVB280-320nm) and long-wave ultraviolet rays (UVA320-400nm). Most of the UVC short-wave ultraviolet rays (100-280nm) are blocked by the ozone layer, and medium-wave ultraviolet rays are mainly absorbed by the epidermis, damaging the epidermis. Long-wave ultraviolet rays can reach the upper part of the dermis and can act on blood vessels and other tissues. Conventional ultraviolet protection measures include the use of sunscreen and anti-ultraviolet umbrellas. The use of sunscreen can only block part of UVA, but it is not very effective for UVB. Ultraviolet radiation is very harmful to the human body, causing the skin to darken and even produce spots and inflammation. Therefore, people are paying more and more attention to anti-ultraviolet rays, and the market demand for outdoor sun protection is increasing. However, the anti-UV fabrics currently on the market generally have problems such as low UV resistance level, reduced wearing comfort of the fabric after finishing with additives, and unsatisfactory anti-UV timeliness.

[0005] In summary, existing outdoor clothing has the following problems: 1) The fabric is not very comfortable; 2) Ordinary warp-knitted elastic fabrics have weak outdoor UV resistance and the effect is not long-lasting, and the anti-UV ecological effect will further reduce the wearing comfort. Utility Model Content

[0006] The purpose of the utility model is to provide a high-performance dense-gauge warp-knitted outdoor fabric, which is suitable as an outdoor leisure sports fabric and has the effects of anti-see-through, breathable and moisture-absorbent, soft and skin-friendly, clear texture, and no wrinkles or bulging when stretched. It has a long-lasting high-performance anti-UV ecological function and protects people's skin health.

[0007] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0008] High-performance close-gauge warp-knitted outdoor fabric, including fabric, the fabric is woven from 34F nylon and Lycra elastic yarn, the fabric adopts close-gauge E36 needle machine number, double-comb warp knitting organization, the double-comb organization specifically includes front comb GB1 and back comb GB2, the front comb GB1 and back comb GB2 both adopt 01 / 21 / 32 / 12 / / four-row warp satin organization, wherein 01 and 32 are open coils, and 21 and 12 are closed coils.

[0009] It should be noted that in this application, 1) the fabric texture of the traditional E32 needle machine number can no longer achieve the design effect of the new fabric, so it is changed to the dense needle gauge E36 needle machine number to enhance the tightness of the fabric coil texture and reduce the fabric's UV transmittance. 2) The process organization changes the traditional 23 / 10 / / +10 / 12 / / elastic fabric organization to a new non-traditional 01 / 21 / 32 / 12 / / special organization, which minimizes the needle extension line to achieve a new texture effect, and fully considers the use of the opening and closing of the coil, so that the new fabric has a clear texture and dimensional stability, achieving an imitation woven effect, suitable for the tight drape characteristics of outdoor sportswear.

[0010] In one embodiment of the present invention, the specifications of the fabric are: width 140cm, weight 115g / m 2 ,Spandex content: 19.6%.

[0011] In one embodiment of the present invention, the fabric specification is: spandex content: 20%.

[0012] In one embodiment of the present invention, TiO2 is added to the fabric.

[0013] In one embodiment of the present invention, the cross-section of the fabric is a flat caterpillar shape.

[0014] It should be noted that the present application changes the traditional circular cross-section into a flat caterpillar-shaped cross-section to increase the contact area between the fabric and the skin and enhance the reflection and blocking ratio of ultraviolet rays. At the same time, TiO2 powder material is evenly added to the new raw material. The TiO2 powder reflects the UVA entering the fabric, absorbs UVB and converts it into low-energy harmless light for emission. The caterpillar cross-section has better adhesion to block ultraviolet rays, lowers the UVA transmittance, and improves the instantaneous coolness of the fabric. It can also make the new fabric have better anti-see-through effect, and utilizes multiple F-number ultrafine nylon to enhance the softness and skin-friendly effect of the fabric.

[0015] In one embodiment of the present invention, the Lycra elastic yarn is Lycra acid-dyeable spandex.

[0016] It should be noted that for the development of dyeing and finishing processes, environmentally friendly, energy-saving and economical dyeing processes can be considered. When dyeing, it is possible to consider adding an appropriate amount of ultraviolet shielding agent and dyeing in the same bath to enhance the UPF multiple and UVA transmittance of the fabric. In order to improve the comfort of the fabric during finishing, antibacterial, moisture absorption and perspiration, and cool finishing are considered to increase the comfort of the new anti-UV fabric. At the same time, in view of the particularity of the satin needle organization, the improvement of the dyeing and finishing process and the optimal screening of dyes are maximized to ensure the uniform coloring of the new anti-UV fabric and improve the quality. Lycra elastic yarn can also be selected as Lycra acid-dyeable spandex.

[0017] The beneficial effects of the utility model are:

[0018] First, the present application selects the E36 needle gauge with a dense needle pitch, and transforms the traditional E32 warp knitting machine into the E36 needle gauge, so as to achieve effective adjustment of the groove needles, needle cores, and sinkers to meet the requirements of small and tight loop formation.

[0019] Second, the fabric of the present application is woven from high F-number nylon and Lycra elastic yarn. High-F-number high-quality nylon is selected as the raw material and equipped with high-quality Lycra elastic yarn, so that the fabric has unparalleled excellent elasticity and instantaneous resilience, overcoming the disadvantage of woven fabrics that are not close-fitting and enhancing the care and comfort of the fabric for muscles and joints.

[0020] Third, the process organization of the present application is specially designed for the characteristics of outdoor sports fabrics, changing the traditional front-combed 23 / 10 / / warp pile organization to a new and unconventional 01 / 21 / 32 / 12 / / four-row warp satin organization, wherein 01 and 32 are open coils, which enhance the smoothness of the new fabric, and 21 and 12 are closed coils, which enhance the texture effect of the new fabric and reduce the slippage and transferability of the coils, so that the new fabric has a strong dimensional stability and texture. The needle movement distance of each needle in the new process organization is reduced to the shortest needle, which reduces the floating thread effect of the knitted fabric, improves the hooking defect, and enhances the flatness of the fabric. The back combing also changes its traditional 10 / 1 2 / / structure, and adopts 01 / 21 / 32 / 12 / / four-row warp satin structure which is consistent with the front combing needle movement, so that the elastic yarn is covered by nylon inside and not exposed, so as to give full play to its excellent elasticity and recovery. The special process structure makes the new fabric have excellent air permeability, moisture absorption, elasticity and recovery, and also makes the new fabric have fine texture, tight texture, and smooth drape. The new fabric is smooth, crisp, flat and fine, with clear texture. The fabric will not produce wrinkles and bulges when stretched and recovered, and always maintains close-fitting shaping. It will not have rough edges or curling edges when cut, and can be cut arbitrarily without falling apart. It is an ideal outdoor sports leisure and fashion fabric.

[0021] Fourth, the specifications of the fabric of this application are: width 140cm, weight 115g / m 2 ,Spandex content: 19.6% or 20%. In order to make the new anti-UV fabric have better four-sided elasticity, the spandex content is generally controlled at around 20%, and the warp knitted fabric is more comfortable and functional.

[0022] Fifth, the application selects new functional yarns, and in response to the requirements of new anti-UV fabrics, permanent functions are achieved not through a single means of post-finishing, but through special innovations in raw materials. The spinning cross-section in the shape of a flat caterpillar and the uniform addition of TiO2 powder materials to the new raw materials, the TiO2 powder reflects the long-wave UVA entering the fabric, absorbs the medium-wave UVB and converts it into low-energy harmless light, so that the utility model The patented fabric has a natural high-performance anti-UV effect, especially without sacrificing the comfort of the fabric itself.

[0023] Sixth, in order to improve the dyeing quality of new fabrics, consider using Lycra acid-dyeable spandex to make the new fabrics have uniform color effects and good color consistency, which improves the quality of the finished product. If the subsequent dyeing and finishing process is considered, high-quality environmentally friendly dyes can be selected to make the new fabrics have extremely high color uniformity and improve the wearing grade of the new anti-UV fabrics. When dyeing, consider adding an appropriate amount of ultraviolet shielding agent and dyeing in the same bath to enhance the UPF multiples and UVA transmittance of the fabric. In order to improve the comfort of wearing the fabric during post-finishing, consider antibacterial, moisture absorption and perspiration, and cool finishing to increase the comfort of the new anti-UV fabric.

[0024] In summary, the present application can solve the problems that ordinary warp-knitted elastic fabrics have weak outdoor anti-UV function, short-lasting effect, and anti-UV ecological effect reduces wearing comfort, so that the fabric has the advantages of traditional knitting and weaving, and is suitable as outdoor leisure sports fabric, achieving the effects of anti-see-through, breathable and moisture-absorbent, soft and skin-friendly, clear texture, and no wrinkles or bulging when stretched. It has long-lasting high-performance anti-UV ecological function and protects people's skin health. BRIEF DESCRIPTION OF THE DRAWINGS
