Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, and more specifically, to knitted fabrics made of polyamide fiber material with a small spring molecular structure. Background Technology

[0002] With the booming development of outdoor sports and people's pursuit of a healthy, lightweight, and comfortable lifestyle, consumers have increasingly higher demands for clothing, not only focusing on aesthetics but also having higher expectations for functionality and comfort. Traditional natural fiber fabrics, such as cotton, linen, and silk, while offering excellent skin-friendly comfort, have significant shortcomings in functionality. For example, cotton fibers are highly absorbent, and moisture does not evaporate quickly in humid and hot environments, resulting in a sticky and stuffy feeling when worn; linen fibers wrinkle easily, affecting both comfort and aesthetics; and silk fibers perform poorly in terms of antibacterial and UV protection.

[0003] Meanwhile, new types of synthetic fiber materials are constantly emerging, such as polyamide, polyester, polyurethane, aramid, and high-strength fibers. These synthetic fiber materials have significant functional advantages; for example, polyamide fibers have good abrasion resistance, moisture absorption, and strength; polyester fibers possess quick-drying, wrinkle-resistant, and UV-resistant properties. Moreover, continuous technological advancements in the textile and synthetic fiber industry, such as the application of functional silk-like processes and physical finishing technologies, have strongly promoted the rapid development of functional synthetic fiber fabrics. However, existing fabrics still have some shortcomings, such as the difficulty in moisture absorption of traditional synthetic fibers, resulting in a poor wearing experience.

[0004] Therefore, a knitted fabric made of polyamide fiber material with a small spring molecular structure is proposed, which can take into account both the comfort characteristics of natural fibers and the multiple functional advantages of new chemical fiber materials. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a knitted fabric of polyamide fiber material with small spring molecular structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a knitted fabric made of polyamide fiber material with a small spring molecular structure, comprising multiple knitted structures woven from first fiber yarns and second fiber yarns, wherein the first fiber yarns and second fiber yarns are woven in a double-sided variable structure, and both the first fiber yarns and second fiber yarns are spirally curled into small spring molecular shapes, and each knitted structure is in a six-way cycle, wherein the six ways include the first way, the second way, the third way, the fourth way, the fifth way, and the sixth way, wherein the first way, the second way, the fourth way, and the fifth way are all woven from the first fiber yarns, and the third way and the sixth way are all woven from the second fiber yarns.

[0007] Preferably, both the first fiber yarn and the second fiber yarn are polyamide fibers.

[0008] Preferably, the length of the first fiber yarn loop in the first, second, fourth, and fifth paths is 25cm / 100 loops.

[0009] Preferably, the second fiber yarn coil length of the third and sixth paths is 23cm / 100 coils.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By using 50D / 48F high-fill modified polyamide yarn on a weft-knitted circular knitting machine to develop a variable double-sided elastic knitted fabric, this lightweight polyester fiber yarn features a unique 3D hand feel, a bouncy effect, exceptional stability, long-lasting and stable elasticity, resistance to fatigue and aging, and the fabric does not bulge, deform easily, or curl at the edges. Its superior properties, such as its three-dimensional micro-spring mesh molecular structure, combined with the novel variable double-sided knitting process, result in a fabric that is lightweight, fluffy, soft, smooth, and elastic, resistant to pilling, and offers a comfortable and unrestricted wearing experience. It meets the requirements for comfortable outerwear and is an excellent choice for lightweight and fluffy clothing such as T-shirts and polo shirts. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the fabric structure of this utility model.

[0014] The attached diagram is labeled as follows: 1. First route; 2. Second route; 3. Third route; 4. Fourth route; 5. Fifth route; 6. Sixth route. Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As attached Figure 1 and Figure 2The knitted fabric made of polyamide fiber material with a small spring molecular structure shown includes multiple knitted structures woven from first fiber yarns and second fiber yarns. The first and second fiber yarns are woven in a double-sided variation structure. Both the first and second fiber yarns are spirally curled into small spring molecular shapes. Each knitted structure is in a six-way cycle, where the six ways include the first way 1, the second way 2, the third way 3, the fourth way 4, the fifth way 5, and the sixth way 6. The first way 1, the second way 2, the fourth way 4, and the fifth way 5 are all woven from the first fiber yarn, while the third way 3 and the sixth way 6 are woven from the second fiber yarn.

[0017] Both the first and second fiber yarns are 50D / 48F high-fill modified polyamide yarns.

[0018] The length of the first fiber yarn loops in the first path 1, the second path 2, the fourth path 4, and the fifth path 5 is 25cm / 100 loops.

[0019] The second fiber yarn loop length of the third path 3 and the sixth path 6 is 23cm / 100 loops.

[0020] Specifically, by using 50D / 48F polyamide fiber yarn to create a modified double-sided knitting structure on a weft-knitting circular knitting machine, this fiber yarn is a special elastic fiber produced by modifying the spinning process using high-tech three-dimensional modified polyamide raw materials. By changing the different yarn feeding speeds of the upper and lower rollers of the spinning machine and adjusting the appropriate tension between the yarn beam rotor and the upper and lower rollers, the design specifications are achieved. This causes the yarn to generate a spiral curled small spring molecular structure during the pre-twisting and heating process. The purpose is to solve the problem of achieving an ultra-light and fluffy feel in the fabric that cannot be achieved by ordinary spinning processes due to early intervention in weaving and finishing. The yarn with the spiral curled small spring molecular structure can also improve the physical pilling and snagging performance of clothing fabrics, which is caused by fiber breakage and pilling due to friction and scratching in the wearing environment, thus enhancing the comfort of the fabric in terms of the wearing experience.

[0021] In practice, the first row 1 is knitted synchronously by the upper needle plate and lower needle cylinder of the circular knitting machine. It is divided into the front and back sides of the fabric structure. The front loops are knitted in the lower needle cylinder of the circular knitting machine using a looping process, while the back loops are knitted in the upper needle plate of the circular knitting machine using a looping and floating yarn process. The front process is knitted using two different needles arranged in a cyclical pattern with an interval of 1. Figure 2As shown in the first track 1 loop diagram, the B-type needle knits on the front side of the fabric structure using a looping technique, while the A-type needle knits on the front side of the fabric structure, i.e., on the needle cylinder needle, using a floating yarn (no needle movement) technique. At the corresponding needle cylinder position of the A-type needle, loops are knitted on the needle cylinder position using a looping technique, and at the corresponding needle cylinder position of the B-type needle, loops are knitted on the needle cylinder position using a floating yarn technique. That is, the entire loop track is knitted in an "S" shape between the upper and lower needles (the front and back sides of the fabric structure) in a continuous looping alternation. The yarn for this track is preferably 50D / 48F high-fill modified polyamide fiber yarn, whose inherent special fiber material yarn can effectively improve the structural stability and good lightweight physical properties of the garment fabric.

[0022] The second route, consisting of two loops, is completed simultaneously on the upper needle plate and lower needle cylinder of a circular knitting machine. It is divided into the front and back sides of the fabric structure. The front loops are knitted in the lower needle cylinder using a loop-forming technique, while the back loops are knitted in the upper needle plate using a combination of loop-forming and float-yarn techniques. The front loops are knitted using two different needles arranged in a 1-1 alternating cycle, as shown below. Figure 2 As shown, in the second path 2, the A-type needle is knitted on the front side of the fabric structure using a looping technique, while the B-type needle is knitted on the front side of the fabric structure, i.e., on the needle cylinder needle, using a floating yarn (no needle movement) technique. At the corresponding needle cylinder position of the A-type needle, the needle cylinder is knitted using a floating yarn technique at the needle cylinder position, and at the corresponding needle cylinder position of the B-type needle, the needle cylinder is knitted using a looping technique at the needle cylinder position. That is, the entire loop trajectory is knitted in a "Z" shape continuously and alternately between the upper and lower needles (the front and back sides of the fabric structure). The yarn for this path is preferably 50D / 48F high-fill modified polyamide fiber yarn.

[0023] The third route 3 is woven by alternating 1-1 loops of two different needles, A and B. This route is woven using a looping process on the lower cylinder of a large circular knitting machine, presenting the front effect of the fabric structure. The yarn for this route is preferably 50D / 48F high-fill modified polyamide fiber yarn.

[0024] The fourth method involves the same weaving technique and yarn selection as the fabric structure. Figure 2 The second path, 2, is shown.

[0025] The fifth and fifth weave fabrics use the same weaving techniques and yarn selection as the fabric structure. Figure 2 The first path shown is 1.

[0026] The weaving process and yarn selection for the sixth-row 6 fabric are the same as those for the fabric structure. Figure 2 The third path shown is 3.

[0027] This invention utilizes 50D / 48F high-loft modified polyamide yarn to develop a modified double-sided elastic knitted fabric on a weft-knitted circular knitting machine. This lightweight polyester fiber yarn features a unique 3D hand feel, a bouncy texture, exceptional stability, long-lasting elasticity, and resistance to fatigue and aging. The fabric does not bulge, deform easily, or curl at the edges. Its superior properties, such as its three-dimensional micro-spring mesh molecular structure, combined with the novel modified double-sided knitting process, result in a lightweight, fluffy fabric with a soft, smooth, and elastic feel. It is resistant to pilling and provides a comfortable, pressure-free wearing experience, meeting the needs of comfortable outerwear. It is an excellent choice for comfortable clothing fabrics such as T-shirts and polo shirts, fulfilling the expectations of a fluffy and lightweight design.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
