Description

Technical Field

[0001] The present application relates to the technical field of knitted fabrics, and in particular to a double-sided weft-knitted fabric with moisture absorption, quick drying, antibacterial and UV protection functions. Background Art

[0002] As casual clothing in daily life, knitted POLO shirts are generally required to have a smooth appearance, visually crisp, soft touch, moisture absorption and perspiration, quick drying and breathability, and good antibacterial and antibacterial properties. Existing knitted POLO shirts, if woven with cellulose fibers such as cotton and viscose, have good moisture absorption and breathability, and are soft to the touch, but lack quick drying and easy care functions; if woven with chemical fibers such as polyester and nylon, although they have good quick drying and iron-free characteristics, they have poor moisture absorption, strong aurora feeling of chemical fibers, and poor anti-pilling performance. How to combine the performance advantages of different fibers of the two, so that knitted POLO shirts not only have the moisture absorption, softness, and breathability characteristics of cotton fibers, but also have the stiffness, moisture conduction, quick drying, and easy care characteristics of chemical fibers. The existing technology generally uses chemical fibers and natural fibers to blend or interweave, and the products have the softness, moisture absorption, and breathability of cotton, as well as the stiffness and easy drying characteristics of polyester. However, the existing technology still does not have excellent moisture absorption and quick drying functions. Utility Model Content

[0003] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0004] The present application provides a double-sided weft-knitted fabric with moisture absorption, quick drying, antibacterial and UV protection functions. The fabric not only has the effect of different appearance patterns on both sides, but also has the functions of moisture absorption, quick drying, antibacterial and anti-bacterial, and UV protection, as well as a sensory effect of soft touch and refreshing appearance.

[0005] In some embodiments, the double-sided weft-knitted fabric with moisture absorption, quick drying, antibacterial and UV protection functions includes a fabric body, wherein the fabric body is a double-sided fabric, one side of the double-sided fabric is composed of a smooth effect surface woven by a single yarn, and the other side of the double-sided fabric is composed of a concave-convex effect surface woven by a double yarn, the smooth effect surface is woven by a single-sided loop coil, the concave-convex effect surface is composed of a staggered arrangement of a protruding area and a recessed area, the protruding area is woven by continuous single-sided loop coils, and the recessed area is connected by a single-sided loop coil and a double-sided collection loop coil.

[0006] Optionally, the single yarn is a modified polyester filament with a fineness specification of 75D / 72F.

[0007] Optionally, the double yarns are two modified polyester filaments with a fineness specification of 75D / 72F.

[0008] Optionally, the protruding area is knitted by two consecutive single-sided loops.

[0009] Optionally, the recessed area is knitted by a single-sided loop coil and a continuous secondary single-needle single-row double-sided tuck coil.

[0010] Optionally, the square meter weight of the fabric body is 220g / m 2 .

[0011] The double-sided weft-knitted fabric provided in the present application has both moisture absorption and quick drying as well as antibacterial and UV protection functions, which can achieve the following technical effects:

[0012] First, it has different appearance effects on both sides: the present application adopts single yarn and double yarn alternating weaving, and ribbed double-sided double-layer fabric structure design, so that the two sides of the double-sided fabric have different appearance effects: the single yarn weaving one side of the fabric forms a fine, clean and smooth effect surface with looped coils, and the double yarn weaving one side forms a protruding area through single-sided weaving of adjacent continuous needles, and the single-sided weaving and double-sided looping and looping connection form a recessed area. The protruding area and the recessed area are alternately combined to form a rough concave-convex effect surface, so that the fabric of the present application has a two-sided effect with the same raw materials, different appearance patterns and styles on both sides. The fabric is woven with the same fiber raw materials, which is not only simple in post-finishing processes such as dyeing and processing, but also can be worn on both sides.

[0013] Second, it has the functions of moisture absorption, quick drying, antibacterial and UV protection: modified polyester filament fiber is used. The fiber has hydrophilic groups grafted on the polyethylene terephthalate polymer chain and adopts a Y-shaped cross-section and micro-groove physical morphology structure. Therefore, it has excellent moisture absorption, moisture conduction and quick-drying properties, and the fabric does not need to be treated with auxiliary agents during the dyeing and finishing process to achieve the moisture absorption and perspiration requirements; because the grafted hydrophilic groups have good antibacterial properties, and the fiber has excellent moisture absorption and quick-drying properties, a dry environment is created where bacteria are not easy to reproduce, so that the modified polyester filament l fiber has certain antibacterial and antibacterial effects, and has good UV resistance.

[0014] Third, it has a refreshing appearance and a soft touch style effect: using modified polyester filaments with a fineness specification of 75D / 72F, firstly, using fine denier filaments to improve the overall softness of the fabric; secondly, through the single yarn and double yarn fabric structure design and weaving process design, the single yarn weaving surface has fine yarns, the loops are flat, and the touch is smooth and soft; the double yarn weaving surface, due to the continuous looping of the double yarn on one side, and the double yarn double-sided looping and looping weaving, constitutes a concave and convex effect surface texture, which is stiffer than the single yarn weaving surface. The fabric has a refreshing appearance and a soft touch style effect by combining the single yarn and double yarn weaving and fabric structure design; the ribbed composite structure of the fabric gives the fabric good dimensional stability, and the double-sided single needle single row looping organization point has a micro-pore structure, which increases the breathability of the fabric, so it is suitable for the preparation of business-oriented POLO shirts and can improve wearing comfort.
