Description

Technical Field

[0001] This utility model belongs to the field of knitted fabric technology, specifically relating to differentiated cotton-feel knitted lightweight fleece-feel fabric. Background Technology

[0002] In today's textile industry, with the improvement of people's quality of life and their love for outdoor sports, the demand for functional fabrics is growing. Especially in terms of thermal fabrics, consumers not only pursue warmth, but also have higher expectations for the fabric's lightweight, breathability, resilience, and skin-friendliness.

[0003] Traditional knitted thermal fabric manufacturing processes have many shortcomings. For example, common fleece sweatshirts use a three-thread fleece knitted loop structure and achieve their warmth after finishing. However, they rely on the thickness of the fleece for warmth, making them feel bulky in light physical activities. They also have poor breathability and moisture permeability, which can easily lead to a stuffy feeling. Furthermore, after multiple washes, the fibers are prone to tangling, shedding, and pilling, reducing wearing comfort and warmth, and limiting the occasions in which the clothing can be worn.

[0004] Furthermore, existing circular knitting machines have reliability defects in loop formation during the loop loop circulation and needle withdrawal structure of the lower cylinder: 1. After the needle is withdrawn from the lower cylinder, the distance between adjacent needles increases. The traditional cam motion cannot adapt to the different yarn tensions in the withdrawal area and the non-withdrawal area, which will lead to uneven loop lengths. For example, the yarn in the withdrawal area is loose, while the yarn in the non-withdrawal area is tight.

[0005] 2. When the triangular trajectory is switched frequently, the curve smoothness of the ordinary triangular system is insufficient, which can easily cause needle collision or inconsistent tucking height. Utility Model Content

[0006] The purpose of this invention is to provide a differentiated cotton-feel knitted lightweight fleece-feel fabric.

[0007] To achieve the above and other related objectives, this utility model provides the following technical solution: A differentiated cotton-feel knitted lightweight fleece fabric, including a double-sided weft-knitted draw-needle fleece structure, which is applied on a double-sided 32-needle cylindrical knitting machine. The upper needle plate triangle is divided into two sections AB, and the lower needle cylinder triangle uses one section A. Each cycle consists of 4 loops. The first and third loops are woven into loops on the upper needle plate (AB section) and floated on the lower needle cylinder (A section). The second loop is woven into loops on the upper needle plate (A section), floated on the lower needle cylinder (B section), and looped on the lower needle cylinder (A section). The fourth loop is woven into loops on the upper needle plate (AB section), floated on the lower needle cylinder (A section).

[0008] Preferably, a ribbed needle pairing structure is adopted, with the upper needle plate fully threaded and the lower needle cylinder arranged in a 1-empty-1-needle cycle, and the needle pairs are arranged horizontally in sequence.

[0009] Preferably, a double-sided three-dimensional structure is adopted, with the surface layer of the fabric made of polyester bicomponent composite high-elastic imitation cotton filament, and the connecting layer and the bottom layer made of octagonal hollow cross-section ultrafine polyester filament.

[0010] It should be noted that, in adopting the above technical solution, this application also screened and optimized the fabric raw materials. The reasons are as follows: To address the aforementioned technical challenges, the industry has continuously explored and innovated. For example, some designs employ a three-layer air-layer knitting structure combined with differentially shaped fibers, utilizing the cavities of hollow fibers to provide still air and enhance warmth. Simultaneously, structural and technological innovations achieve breathability and warmth retention. Others utilize a special bottom layer design, controlling the coil structure and napping process to solve problems such as poor elasticity and a tighter feel after washing in traditional knitted napped fabrics, thus improving warmth retention and fabric performance. The patent with announcement number CN112030329A uses a three-layer hollow layer structure and a raised polyester coil design in the bottom layer for easy napping with steel needles, solving the problem of traditional plain-weave air-layer fabrics being difficult to nap. However, it does not use hollow fiber yarn to create a fleece-feeling functional fabric.

[0011] In terms of fiber materials, composite yarns of octagonal hollow cross-section polyester and polyester microfiber are gradually gaining attention. Their unique octagonal hollow structure increases the porosity between fibers, improving warmth retention and providing excellent breathability. Polyester bicomponent composite elastic cotton-like yarn also possesses good cotton-like feel and a certain degree of elasticity due to its cotton-like characteristics, giving it unique advantages in fabric applications. However, current research on combining these special fiber materials with innovative weaving structures to prepare high-performance, lightweight, fleece-like knitted fabrics is still insufficient.

[0012] Preferably, the fiber fineness of the polyester bicomponent composite high-elastic cotton-like filament is 60Dtex-80Dtex.

[0013] Preferably, the microfiber polyester filament with an octagonal hollow cross section has a fiber fineness of 40 Dtex-80 Dtex.

[0014] It should be noted that, in adopting the above technical solution, this application has also screened and optimized the fabric raw materials. This application, by employing a double-sided three-dimensional structure, combining octagonal hollow cross-section ultrafine fiber polyester filaments with polyester bicomponent composite high-elastic cotton-like filaments, and a special weaving structure, produces a differentiated cotton-feel knitted lightweight fleece-like fabric with a novel appearance, breathability, and good resilience, as well as comfortable, skin-friendly, and warm properties, to meet the market demand for high-quality functional fabrics.

[0015] Preferably, the hollowness of the polyester bicomponent composite octagonal hollow cross section microfiber polyester filament is >15%, and the coefficient of variation is >16%.

[0016] Preferably, the weight range of the differentiated cotton-feel knitted lightweight fleece-feel fabric is 150-200 g / m². 2 .

[0017] It should be noted that, by employing the above technical solution, the addition of polyester bicomponent composite high-elastic cotton-like filaments gives the fabric excellent resilience and more comfortable, skin-friendly, and warm properties. The addition of polyester bicomponent composite octagonal hollow cross-section microfiber polyester filaments gives the fabric a lighter and softer feel.

[0018] Furthermore, the mass fraction of the polyester bicomponent composite high-elastic cotton-like filament is 50-60%.

[0019] Furthermore, the mass fraction of the octagonal hollow cross-section microfiber polyester filament is 40-50%.

[0020] The beneficial effects of this utility model are: First, regarding the aforementioned defects in the reliability of loop formation in the existing circular knitting machine during the loop loop cycle and needle withdrawal structure of the lower needle cylinder, this application solves the problem by having "every four loops form a cycle, with the first and third loops forming loops in the AB section of the upper needle plate and floating yarn in the A section of the lower needle cylinder; the second loop forming loops in the A section of the upper needle plate, floating yarn in the B section, and forming loops in the A section of the lower needle cylinder; and the fourth loop forming loops in the AB section of the upper needle plate and forming loops in the A section of the lower needle cylinder". In the first and third loops, when the AB section of the upper needle plate forms loops and the A section of the lower needle cylinder is floating yarn, the yarn in the needle withdrawal area (without needles in the lower needle cylinder) is in a floating state, and the yarn tension is naturally released, avoiding excessive tension caused by the lack of needle grip.

[0021] Routes 2 and 4: When forming loops in the non-needle-withdrawing area (with needles in the lower needle cylinder), the upper needle plate releases yarn synchronously (float yarn design), increasing the yarn supply to compensate for the length required for loop formation and preventing the yarn from being too tight in the non-needle-withdrawing area.

[0022] Through the structural design of this application, tension can be actively released in the needle-pulling area and the yarn supply can be increased in the non-needle-pulling area to achieve dynamic tension balance without the need for an additional tension compensation mechanism.

[0023] This application separates complex knitting movements (such as section A of the needle bed in the second row) into a single triangle segment, avoiding the simultaneous processing of knitting, tucking, or floating yarn within the same triangle segment. Other triangle segments perform only a single movement, such as sections B of the first and third rows, which only form knitting. This design avoids problems such as needle collisions or inconsistent tucking heights.

[0024] Secondly, this application also screened and optimized the raw materials for the fabric. By adopting a double-sided three-dimensional structure, combining ultra-fine polyester filaments with octagonal hollow cross-sections and polyester bicomponent composite high-elastic cotton-like filaments, as well as a special weaving structure, this application prepared a differentiated cotton-like knitted lightweight fleece-like fabric with a novel appearance, breathability and sweat-free properties, as well as good resilience, comfort, skin-friendly and warmth retention, to meet the market demand for high-quality functional fabrics.

[0025] Third, this application verifies the actual performance of the fabric. The differentiated cotton-feel knitted lightweight fleece-feel fabric of this application meets the following standards: Thermal insulation rate (GB / T 35762-2017): ≥30%; Clo value (clo): ≥0.3; Thermal resistance (K·m) 2 / W): ≥0.06; Heat transfer coefficient (W / m) 2 (℃): ≥15; Air permeability (GB / T 5453-1997): ≥100mm / s; Moisture wicking performance (according to GB / T 21655.2-2019 standard): ≥3 level.

[0026] Fourth, the differentiated cotton-feel knitted lightweight fleece fabric of this application can achieve a novel and unique appearance and a soft and skin-friendly feel, which can expand the scope of application and not limit the wearing scenarios of clothing. For example, it can be a lightweight, warm, breathable and comfortable sportswear fabric. Attached Figure Description
