Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a mechanically elastic cotton-like knitted fabric. Background Technology

[0002] Knitted fabric is a type of fabric made by interlocking loops of one or more yarns. It is a flexible fabric formed by bending yarns into loops and interlocking loops. The most fundamental characteristic of knitted fabric is its loop structure. It is elastic, soft and comfortable, and is one of the most common and frequently worn fabric types in our daily lives.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain shortcomings: Currently, most conventional imitation cotton fabrics on the market suffer from the pain point of not being able to achieve both the imitation cotton texture and durable elasticity. Some imitation cotton fabrics have poor elasticity and feel restrictive when worn. Some imitation cotton fabrics rely too much on elastic fibers such as spandex, and their elasticity deteriorates quickly after long-term use. In addition, some fabrics also have problems such as stiff hand feel, poor breathability, and insufficient UV protection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a mechanically elastic cotton-like knitted fabric that exhibits minimal elasticity loss, softness, good skin-friendliness, and low constraint.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mechanically elastic imitation cotton knitted fabric, comprising a fabric body formed by a single-sided circular knitting machine, wherein the fabric body comprises a first yarn, the first yarn having a 10-way weaving structure, and each of the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th ways of the first yarn consisting of 2 loops.

[0006] A further improvement is that the first needle of the first and second needles of the first yarn forms a loop, the second needle gathers the loop, and the rest are not knitted.

[0007] A further improvement is that the second needle of the 3rd, 5th, and 9th needle banks of the first yarn forms a loop, the first needle of the needle plate forms a loop, and the rest are not knitted.

[0008] A further improvement is that the first needle of the 4th, 8th, and 10th needle banks of the first yarn forms a loop, the second needle of the needle plate forms a loop, and the rest are not knitted.

[0009] A further improvement is made: the first needle of the 6th and 7th needle cylinders of the first yarn is knitted in a loop, the second needle is knitted in a loop, and the rest are not knitted.

[0010] A further improvement is that the fabric itself has a width of 158cm, a weight of 155g / m², and is composed of 100% nylon.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This new fabric is woven from a first yarn formed by two loop structures. This yarn has high shrinkage characteristics and forms a spiral twisted structure after high-temperature dyeing and finishing. It generates stable rebound through physical structure rather than relying on the deformation of elastic fiber molecular chains, thus achieving almost no reduction in mechanical elasticity. At the same time, by optimizing the yarn length, the problem of stiff hand feel caused by the initial yarn length being too short is solved, giving the fabric a warm and friendly touch similar to cotton, satisfying consumers' preference for the feel of cotton.

[0012] This utility model fabric uses a double-sided jacquard dot weave structure. Each loop contains four single-layer tufted units distributed in pairs. The tufted yarn padding creates a slightly raised dot texture on the fabric surface, which not only provides a cotton-like rough feel but also increases the fabric porosity. It is woven on a single-sided circular knitting machine and combined with dyeing and finishing processes such as ultrasonic washing. The yarn shrinks rapidly at high temperatures, making the loops tighter. This reduces the risk of fiber snagging due to friction and improves anti-pilling and anti-snagging performance as well as UV protection. At the same time, the double-sided jacquard structure retains a certain porosity to ensure breathability. Attached Figure Description

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Example 1:

[0016] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a mechanically elastic imitation cotton knitted fabric, including a fabric body formed by a single-sided circular knitting machine. The fabric body includes a first yarn, which has a 10-way knitting structure. Each of the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th ways of the first yarn consists of 2 loops. In the 1st and 2nd ways of the first yarn, the first needle of the cylinder forms a loop, the second needle of the cylinder forms a loop, and the rest are not knitted. In the 3rd, 5th, and 9th ways of the first yarn, the second needle of the cylinder forms a loop, the first needle of the needle plate forms a loop, and the rest are not knitted. In the 4th, 8th, and 10th ways of the first yarn, the first needle of the cylinder forms a loop, the second needle of the needle plate forms a loop, and the rest are not knitted. In the 6th and 7th ways of the first yarn, the first needle of the cylinder forms a loop. The second needle forms a loop, while the others are not knitted. The fabric itself has a width of 158cm, a weight of 155g / m², and is made of 100% nylon. It uses 48D / 24F mechanical elastic nylon DTY yarn, which is the first yarn, and is woven on a 32G single-sided circular knitting machine. The process yarn length is 15.5cm / 100G (including tuck) and 20cm / 100G (excluding tuck). It is designed with a double-sided jacquard dot structure (including 4 pairs of continuous single-layer tuck units), which solves the problem of stiffness and gives the fabric a cotton-like feel. At the same time, the yarn has high shrinkage characteristics and will form a spiral twisted structure after high-temperature dyeing and finishing. It generates stable rebound through physical structure rather than relying on the deformation of elastic fiber molecular chains, thus achieving almost no reduction in mechanical elasticity. Meanwhile, the fabric uses a double-sided jacquard dot weave structure, with each loop containing four consecutive single-layer tuck units. The tuck padding creates a slightly raised dot texture on the fabric surface, providing a cotton-like rough feel while increasing the fabric's porosity. It is woven on a 32G single-sided circular knitting machine, combined with ultrasonic washing and other dyeing and finishing processes. The yarn shrinks rapidly at high temperatures, making the loops tighter, reducing the risk of fiber snagging and improving anti-pilling and anti-snagging performance as well as UV protection. The double-sided jacquard structure retains a certain porosity, ensuring breathability. Tested according to ISO 9237:1995, the breathability value reaches 290mm / s; tested according to GB / T 18830-2009, the UPF value reaches 600 and the UVA transmittance is 0.13%. Meanwhile, tested according to GB / T 18830-2009 standard, the UPF value reaches 600, UVA transmittance is 0.13%, and UVB transmittance is 0.17%, far exceeding the national standard requirement of 50+, which can effectively block harmful ultraviolet rays and protect skin health; tested according to BS EN ISO 20932-1:2018 standard, the warp elongation is 68.8% and the weft elongation is 93.3%, and the elasticity comes from the physical structure of the yarn and hardly diminishes, achieving "elastic but not loose", adapting to limb movements and not easily deformed; tested according to ISO 9237:1995 standard, the breathability value reaches 290mm / s, meeting the breathability needs of daily commuting. Example 2:

[0017] 1. Taking NF32170, a type of mechanically elastic imitation cotton knitted fabric, as a representative product for analysis, the following tests were conducted. (1) Basic specification parameters test: fiber content, weight, width, shrinkage rate.

[0018] (2) Physical property tests: tensile elasticity, snagging performance, and pilling performance.

[0019] (3) Functional tests: breathability and UV protection performance.

[0020] 2. Test Results and Analysis (1) The basic specifications of mechanical elastic imitation cotton knitted fabric are shown in Table 2.1.

[0021] Table 2.1 Basic Specifications of Mechanically Stretch Cotton-like Knitted Fabric

[0022] (2) The physical property test results of mechanical elastic imitation cotton knitted fabric are shown in Table 2.2.

[0023] Table 2.2 Test results of physical properties of mechanically elastic cotton-like knitted fabric

[0024] As shown in Table 2.2, the mechanically elastic cotton-like knitted fabric, due to its use of high-shrinkage yarn combined with a weft-knitted loop structure, exhibits excellent anti-pilling and anti-snagging properties because the yarn shrinks rapidly after high-temperature dyeing, resulting in smaller and tighter loops. This reduces the risk of fibers being snagged by friction. However, due to the weft-knitted loop structure, it retains a certain degree of tensile elasticity in both warp and weft directions. Its elongation is greater than that of conventional woven tight fabrics but less than that of conventional weft-knitted elastic fabrics. This avoids the stiffness of woven fabrics while preventing deformation due to excessive stretching, achieving a balance of "elastic but not loose." Furthermore, its elasticity stems from the physical deformation of the high-shrinkage yarn during the high-temperature dyeing and finishing process—the yarn forms a spiral twisted structure after high-temperature shrinkage. This structure can stretch and expand under external force, and returns to its original shape after the external force disappears, thus generating stable tensile and rebound properties. More importantly, this elasticity based on the yarn helical structure has "mechanical long-term stability": since the elasticity does not depend on the molecular chain deformation of elastic fibers such as spandex, but rather on the characteristics of the physical structure, it will almost never experience the elasticity decay or degeneration problems caused by molecular chain fatigue and aging after long-term use of conventional elastic fibers. It can maintain stable elasticity performance during repeated stretching, multiple washings and long-term wear.

[0025] (3) The functional test results of mechanical elastic imitation cotton knitted fabric are shown in Table 2.3.

[0026] Table 2.3 Functional test results of mechanically elastic cotton-like knitted fabric

[0027] As shown in Table 2.3, firstly, the high shrinkage of the mechanically elastic cotton-like knitted fabric results in a tighter, more compact fabric, effectively reducing porosity and thus exhibiting excellent UV protection. Both its UPF and UVA transmittance far exceed the national standard of 50+, effectively blocking the penetration of ultraviolet rays, especially the harmful UVA and UVB rays. Secondly, the double-sided small-dot jacquard weave enhances the fabric's three-dimensionality and reduces airflow resistance, achieving a breathability of 290mm / s, sufficient for daily commuting needs.
