Description

Technical Field

[0001] The utility model relates to the field of weft knitting, in particular to an ultra-thin, anti-transmission, freely cut knitted fabric. Background Art

[0002] Knitted fabrics are made of natural fibers, chemical fibers and other yarns. They are made by using loop formation, floating yarn formation, tuck formation, transfer formation, etc., and are formed by using knitting needles on various weft knitting machines to bend the yarns into loops in the horizontal direction and intertwine them with each other.

[0003] Due to the structural characteristics of weft knitted fabrics on the market, after the fabric is cut, the coils at the cut are prone to a series of problems such as unraveling and curling. Currently, most weft knitted fabrics require a series of methods such as piping, locking, and adding gussets to the cuts and edges during the garment making process to solve the problems of unraveling and curling. This not only affects the appearance of the fabric and the wearing effect, but also causes a lot of cutting losses, which is unsightly, uncomfortable, and uneconomical, and obviously runs counter to the current pursuit of fashion, simplicity, and comfort. Weft knitted fabrics are divided into double-sided and single-sided. Double-sided weft knitted fabrics have better anti-unraveling and anti-curling properties than single-sided fabrics. However, in practice, due to various reasons, double-sided weft knitted fabrics are not as widely used as single-sided weft knitted fabrics in some areas of the garment industry.

[0004] The thin single-sided weft-knitted fabrics in the prior art have problems such as curling, curling, and unraveling; and due to structural reasons, such fabrics have defects such as poor air permeability and cannot be cut at will.

[0005] Therefore, it is necessary to provide an ultra-thin, anti-transmission, free-cut knitted fabric to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide an ultra-thin, anti-transmission, free-cut knitted fabric with the properties of plain weave appearance, good elasticity, ultra-thinness, anti-transmission, no shedding, no curling, and free-cutting.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultra-thin, anti-transparent, free-cut knitted fabric, the fabric being a single-sided weft-knitted fabric made by a single-sided weft-knitting circular machine, the basic structure of the weft-knitted fabric being formed by two horizontal coils and one longitudinal coil being looped with each other, the basic structure being: the first coil being a coil-forming structural unit; the second coil being a coil-forming structural unit, the fabric being woven from 20-40D / 24-28F nylon yarn and 20-40D elastic spandex.

[0008] Furthermore, the nylon yarn is a 25D / 24F anti-penetration skin-core nylon composed of a core layer and a skin layer, and the elastic spandex is a 20D low-temperature thermal bonding spandex.

[0009] Furthermore, the length of the nylon yarn for 100 stitches is 15 to 20 cm.

[0010] Furthermore, the finished product weight of the fabric is 90 to 100 g / m2, and the width of the fabric is 135 to 140 cm.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model adopts a weft-knitted coil interwoven knitting structure with stretchable spaces between the yarns, which has better breathability and comfort than woven fabrics. 2. Compared with general free-cut fabrics, this utility model uses a 44-needle 34-inch high-density open-width single-sided weft knitting machine, feeding a skin-core anti-permeability nylon and low-temperature thermal bonding spandex to weave a free-cut single-sided plain fabric that is ultra-thin, anti-permeability, does not fall apart, does not curl, has good breathability, is sun-proof, and is comfortable, stretchable, and dry. 3. This utility model adopts a weft plain needle weaving method, which makes the fabric smooth and has better stretchability, so it will not feel tight when worn. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] See also Figures 1 to 2 As shown, the present invention provides an embodiment of an ultra-thin, barrier-free, free-cut knitted fabric. The fabric is a single-sided plain weft fabric produced on a single-sided circular weft knitting machine. The basic weave structure of the plain weft fabric is formed by interlacing two horizontal rows of coils and one longitudinal loop of coils. The basic weave structure comprises a loop-forming unit (the first loop is a loop-forming unit) and a loop-forming unit (the second loop is a loop-forming unit). The fabric is woven from 20-40D / 24-28F nylon yarn and 20-40D elastic spandex. This nylon-spandex stretch plain weave fabric utilizes 25D / 24F barrier-free nylon core yarn and 20D low-temperature thermally bonded spandex yarn. The single-sided fabric is knitted using a knitting needle arrangement and a diamond-shaped arrangement. After post-processing, it achieves properties such as ultra-thinness, barrier-free, non-fraying, non-curling, free-cutting, excellent breathability, sun protection, and a comfortable, stretchy, and dry feel.

[0016] Please continue reading Figures 1 to 2 As shown, in this embodiment, the nylon yarn is 25D / 24F anti-penetration skin-core nylon composed of a core layer and a skin layer, and the elastic spandex is 20D low-temperature thermal bonding spandex.

[0017] The weft knitting process of this fabric adopts: 2 horizontal rows of coils and 1 longitudinal loop as the pattern return, feeding 25D / 24F anti-leather core nylon and 20D low-temperature thermal bonding spandex, using a 44-needle 34-inch high-density open-width single-sided weft knitting machine. 2 knitting needles form a return position, and the knitting needles are arranged from left to right on the needle cylinder in the order of: 1st level knitting needles, 2nd level knitting needles; 1 loop is a return position, and the water chestnuts are arranged from top to bottom as: loop water chestnut, loop water chestnut.

[0018] The knitting needles are arranged from left to right as shown in the following table.

[0019] The needle arrangement of the needle cylinder is: Level 1 needle Level 2 needle

[0020] Among them: The arrangement of water chestnuts is shown in the following table, where water chestnuts are arranged from top to bottom, and “∧” represents water chestnuts in a circle.

[0021] Syringe angle arrangement: ∧ ∧

[0023] Please continue reading Figures 1 to 2 As shown, in this embodiment, the finished product weight of the fabric is 90-100 g / m2, and the width of the fabric is 135-140 cm.

[0024] The method for weaving the aforementioned ultra-thin, barrier-free, free-cut knitted fabric further includes the following steps: after the greige fabric is unwoven, it is continuously subjected to open-width water washing and degreasing, pre-setting, dyeing, and final setting. The pre-setting temperature is 150-190°C and the machine speed is 18-25 m / min. The final setting temperature is 130-150°C and the machine speed is 18-40 m / min.

[0025] The UV protection factor of the fabric was tested in accordance with GB / T18830-2009 “Evaluation of UV Protection Performance of Textiles”, and the UV protection parameter test data shown in Table 1 below were obtained.
