[0002] With the improvement of living quality and the booming development of outdoor sports, people have higher and higher requirements for the performance of outdoor fabrics. Weft-knitted single-sided high-needle stretch fabrics have always been the darling of the women's underwear market. However, this type of high-needle underwear fabric has the disadvantages of insufficient sun protection and not being cold. There are basically no high-needle stretch and thin fabrics that are truly used for outdoor sun protection. There are also other types of knitted sun-proof stretch fabrics on the market, but the weight is relatively heavy, mostly 180g / m 2 As mentioned above, the application number 202310451900.7 discloses a quick-drying, highly elastic sunscreen fabric, which is provided with a skin-friendly layer, a waterproof layer, and an anti-wrinkle outer layer, and adopts a multi-layer structure to achieve sunscreen. This type of fabric has many layers, a heavy gram weight, and is not cool enough. The waterproof layer has poor moisture absorption effect. In addition, there are many thin woven sunscreen fabrics on the market. Although this type of fabric has good sunscreen performance, it is not cool enough, has poor moisture absorption and breathability, has no elasticity or very little elasticity, and is uncomfortable to wear.

[0010] Figure 1 It is a triangle pattern woven from an ultra-light, sun-proof, weft-knitted single-sided high-needle stretch fabric. DETAILED DESCRIPTION

[0011] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0012] Reference Figure 1 . An ultra-light, thin, sun-proof, weft-knitted, single-sided, high-needle-count stretch fabric, including a fabric body, which is composed of a veil and a padding yarn. The veil is made of 15-20D / 16-24F matte UV-resistant nylon FDY (FULLYDRAWNYARN, fully stretched silk) yarn, and the padding yarn is made of 15-20D spandex. The fabric body has a weft flat needle structure in which one knitting needle and one yarn form a complete cycle, and the yarn arrangement method of the fabric body is one cycle. By selecting 15-20D / 16-24F matte UV-resistant nylon FDY yarn as the veil, it can effectively shield and absorb ultraviolet rays, increase the reflectivity and absorption rate of ultraviolet rays, reduce the transmittance, and play a sunscreen role; by selecting 15-20D spandex as the padding yarn, the fabric has a certain stretchability and recovery.

[0013] The fabric body is a weft plain needle structure with one knitting needle and one yarn forming a complete cycle. The yarn arrangement of the fabric body is one loop and one yarn, and the combination of the fabric yarn makes the woven fabric body ultra-light and thin, with a small weight of 80-100g / m 2 , good sun protection effect, good stretch elasticity, and has certain moisture absorption and breathability; through 1 knitting needle and 1 yarn to form a complete cycle of weft plain needle structure, the fabric body has high-grade and delicate texture, comfortable to wear, and good cooling effect.

[0014] When weaving the fabric body, a 50-60 needle, 34-inch, 108-way weft knitting single-sided circular machine is selected; the needle arrangement method of the fabric body is: all level 1 needles are arranged, the machine speed during knitting is 10-13 revolutions / min, the single machine output is about 400-450 yards / day, the weaving structure is simple, which is conducive to improving production efficiency.

[0015] The yarn feeding amount of the fabric body is: calculated based on the length of 100 coils, the yarn feeding length of the 15-20D / 16-24F matte anti-ultraviolet nylon FDY yarn of the face yarn is 14-17cm, and the yarn feeding length of the 15-20D spandex of the lining yarn is 5.2-6.5cm. Therefore, through this yarn feeding amount, the fabric body has good elasticity and good recovery effect.

[0016] The longitudinal density of the fabric body is cpc50~60, and the transverse density is wpc39~45.

[0017] In the actual weaving process, the veil is preferably 20D / 16F matte UV-resistant nylon FDY yarn, and the lining yarn is 15D spandex, which can meet the corresponding requirements of the fabric body.

[0018] The ultra-light and thin sun-proof weft-knitted single-sided high-needle stretch fabric of the utility model is subjected to corresponding tests, specifically: tested by the textile UV protection performance test ISO standard EN 13758-1:2001+A12006 method, UPF can reach 100+ or ​​more, and UVA≤5%, which has a very good sun protection effect; tested by the AATCC tensile test method LTD 037.5LBS (wire clamp), the longitudinal elongation is 150-180% and the lateral elongation is 220-260%, which shows that the fabric body has very good tensile elasticity, so that the fabric body has the characteristics of good tensile elasticity and comfortable wearing; in addition, after the contact instant coolness performance test (GB / T 35263-2017), the coolness Qmax value of the fabric body is 0.15J / (cm2.s), so that the fabric body has an instantaneous cool effect.

[0019] The fabric body is woven by adopting the above-mentioned weaving structure, needle arrangement method, yarn feeding amount, etc., and the fabric body is woven on a single-sided large circular knitting machine to obtain the fabric body. After the fabric body is woven, it is subjected to dyeing and finishing process. The production process of the dyeing and finishing process is as follows:

[0020] The woven fabric body goes through the following processes in sequence: washing and degreasing, pre-setting, dyeing, post-setting, testing, and finished product inspection; among them, the fabric is washed with open width water to achieve the purpose of degreasing; the dyeing process adopts the commonly used warp cylinder dyeing.

[0021] Among them, open-width water washing and degreasing: add degreasing agent and soda ash into 180 liters of water, set the temperature of the washing tank to 95°C, and the speed to 10-15 m / min to remove oily substances from the fabric yarn and the weaving process. The fabric is curled after open-width water washing and degreasing.

[0022] Among them, pre-setting: pre-setting is carried out in the setting machine, at a temperature of 185-190°C and a machine speed of 18-21 m / min. The fabric specifications are: width of 132-158 cm, weight of 85-105 g / m 2 The pre-setting temperature is 5 to 10°C lower than the conventional pre-setting temperature to ensure that there is no blistering, bruising, or curling on the fabric surface.

[0023] After dyeing, the fabric is post-shaped in the setting machine at a temperature of 150-160°C and a machine speed of 25-30 m / min, making the fabric smoother. The fabric specifications are as follows: width 127-152 cm, weight 80-100 g / m 2 After finalizing, the density of the finished product is maintained between: vertical density cpc50-60, horizontal density wpc39-45.

[0024] The ultra-light and thin sun-proof weft-knitted single-sided high-needle elastic fabric of the utility model is compared with the conventional related fabrics available on the market. Specifically, comparative example 1 uses the commercially available conventional 140g high-needle plain weave structure round glossy and thin weft-knitted elastic fabric, and comparative example 2 uses the commercially available 190g high-needle conventional weft-knitted plain weave structure sun-proof weft-knitted elastic fabric. The weight of each fabric is tested under standard laboratory conditions of 20°C and 65% humidity using the ASTM D3776 method; the tensile elasticity is tested using the LTD 037.5LBS (clip) method; in addition, the EN 13758-1:2001+A12006 method is used to test the ultraviolet resistance UFP and UVA; and the GB / T 35263-2017 method is used to test the coolness Qmax value. The measured performance test data are as follows:

[0025]

[0026] It can be seen from the above table that the ultra-light and thin sun-proof weft-knitted single-sided high-needle stretch fabric of the utility model has the characteristics of small weight, ultra-lightness and thinness, good transverse and longitudinal stretch elasticity, a coolness Qmax value of 0.15, a relatively good coolness, and good anti-ultraviolet effect.

[0027] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
