[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0029] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] Example 1

[0031] like Figures 1-3 As shown, the anti-slip knitted fabric of Example 1 has a knitting structure with two needle tracks on the upper needle plate and two needle tracks on the lower needle cylinder. The knitting pattern is a six-way cycle. According to the arrangement of the upper needle plate to the lower needle cylinder, the six-way pattern is as follows: the first way is float, tuck, tuck, float; the fourth way is tuck, float, float, tuck; the second and fifth ways are loop, loop, float, float; the third and sixth ways are float, float, loop, loop.

[0032] The yarns woven in the first and fourth rows are the first yarn, while the yarns woven in the second, third, fifth, and sixth rows are the second yarn. Furthermore, the first yarn is a first polyester low-elasticity yarn with a fineness of 75D / 36F, and the second yarn is a combed pure cotton high-twist yarn with a count of 34S. The 75D polyester low-elasticity yarn offers higher strength and better durability compared to finer fibers, making it suitable for products that need to withstand more wear. Although it is not the finest fiber, as a low-elasticity yarn, it still possesses a certain degree of elasticity, capable of adapting to a certain degree of stretching while maintaining its shape recovery ability. Due to its relatively large diameter, the fabric may appear slightly thicker, but it still provides good texture and drape. High-twist yarn, by increasing the twist in the yarn, improves its strength and abrasion resistance. This means that clothing made from 34S combed pure cotton high-twist yarn is more durable and can withstand the wear and tear of students' daily activities. Due to its higher twist, fabrics woven from high-twist yarn have better shape retention and are less prone to deformation, helping clothing maintain a good appearance for a long time, remaining like new even after multiple washes and wears. High-twist treatment effectively reduces pilling on the surface of clothing, making it look neater and cleaner, and extending the lifespan of the garment. Although it is high-twist yarn, because it is made from combed pure cotton, it still retains the natural softness and breathability of cotton fibers, ensuring wearing comfort, which is very important for people who wear clothing for long periods of time. Combed cotton is relatively easy to care for, usually has good wrinkle resistance, is easy to wash and quick-drying, and is very suitable for the needs of frequent use in the school environment. Therefore, the combination of the two can create a blended material that combines the abrasion resistance and easy care of polyester with the comfort and natural breathability of pure cotton, making it ideal for producing high-quality student uniforms.

[0033] In Example 1, the yarn length of the first polyester low-elastic yarn in the fabric is 24.2cm / 100 stitches, and the yarn length of the combed pure cotton high-twist yarn is 28cm / 100 stitches.

[0034] The machine is a UTX-2.1DE knitting machine with a 34-inch / 24-g needle count, a total of 2544 needles, and a machine speed of 18 rpm.

[0035] The UTX-2.1DE loom has 72 yarn paths, and the yarn is threaded in the following order: first yarn, second yarn, second yarn, first yarn, second yarn, second yarn.

[0036] Example 1: Fabric properties: Fabric weight 288 g / m² 2 The finished product has a width of 183cm. In the knitted fabric, the first polyester low-elastic yarn of the first yarn accounts for 17.26% of the weight, and the combed pure cotton high-twist yarn of the second yarn accounts for 82.74% of the weight.

[0037] Example 2

[0038] like Figures 4-6 As shown, Example 2 is based on Example 1, except that the first yarn of the anti-slip knitted fabric is a second polyester low-elastic yarn, and the unit yarns in the second yarn include a third polyester low-elastic yarn and spandex yarn. The fineness of the second polyester low-elastic yarn is 30D / 36F, the fineness of the third polyester low-elastic yarn is 50D / 72F, and the fineness of the spandex yarn is 30D.

[0039] The finer fineness of the second polyester low-elasticity yarn makes the fabric feel more delicate and soft; it also makes the fabric lighter and more breathable overall. The finer fibers help improve the drape of the fabric, making the garment look smoother and more natural. The third polyester low-elasticity yarn (50D / 72F) has coarser fibers, resulting in higher strength and better abrasion resistance, able to withstand more stretching and wear; the higher filament count (72F) provides better structural stability and shape recovery, reducing the risk of deformation; the coarser fiber diameter and increased density give the fabric some windproof and waterproof properties. The most significant characteristic of spandex is its excellent elasticity, capable of stretching 5 to 7 times its original length without damage and quickly returning to its original length; spandex fibers are very light, making garments made from it less burdensome to wear; even under stretching, spandex exhibits good strength and durability, and is not easily damaged. By combining two different finenesses of polyester low-elasticity yarn and spandex, the sweatshirt not only has a soft feel and excellent breathability, but also good elasticity, ensuring flexibility and comfort when wearing it.

[0040] In Example 2, the yarn length of the second polyester low-elastic yarn in the fabric is 20.5cm / 100 stitches, the yarn length of the third polyester low-elastic yarn is 25.2cm / 100 stitches, and the yarn length of the spandex yarn is 10.8cm / 100 stitches.

[0041] It uses a VL-DJ knitting machine with a 34-inch / 32G needle count, a total of 3400 needles, and a machine speed of 18 rpm.

[0042] The VL-DJ loom has 72 yarn paths, and the yarn is threaded in the following order: first yarn, second yarn, second yarn, first yarn, second yarn, second yarn.

[0043] Example 2 Fabric properties: Fabric weight 303g / m² 2 The finished product has a width of 145cm. In the knitted fabric, the weight ratio of the second polyester low-elastic yarn in the first yarn is 15.88%, the weight ratio of the second polyester low-elastic yarn in the second yarn is 65.88%, and the weight ratio of spandex yarn is 18.24%.

[0044] The fabric obtained in Example 1 was tested and its properties are as follows:

[0045] 1. Dimensional change rate after washing: At 40℃, after washing with a solution containing 0.02% sodium perborate and 0.003% bleaching activator, and hanging to dry, the length shrinkage rate is 4.3% and the width shrinkage rate is 1.2%.

[0046] 2. Pilling test: GB / T 4802.1-2008 circular trajectory method, 780 centine Newtons of pressure, reaching level 4 (the higher the level, the better the effect);

[0047] 3. Bullet breaking strength: GB / T 19976-2005, steel ball method, steel ball diameter is 38mm; 959N.

[0048] The fabric obtained in Example 2 was tested and its properties are as follows:

[0049] 1. Water washing shrinkage test: Wash in 40℃ water for 12 minutes, air dry, repeat 3 times, warp shrinkage rate 2%, weft shrinkage rate 2%;

[0050] 2. Fabric twist 1%;

[0051] 3. Stretch recovery performance test: Elongation at 30N tensile force: 119.64% in the warp direction and 160.34% in the weft direction; after removing the tensile force and recovering, the elongation of the fabric is 4% in the warp direction and 8.3% in the weft direction.

[0052] 4. Bursting force: 250N;

[0053] 5. Warp density (number of warp yarns) 86 yarns / inch, weft density (number of weft yarns) 57 yarns / inch.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
