Description

Technical Field

[0001] The present application relates to the technical field of knitted fabrics, and in particular to a weft knitted fabric having both moisture absorption, heat generation and antibacterial and quick-drying functions. Background Art

[0002] At present, knitted products with thermal and moisture comfort functions that are light and warm in winter and absorbent and quick-drying in summer are favored by consumers. In the prior art, knitted clothing with warm-keeping functions in winter is generally prepared by selecting fibers with moisture absorption and heat generation functions, fabric structure design containing air layers, and raising the inner layer of fabrics. The moisture absorption and heat generation fabrics are mainly cellulose fibers and natural fibers with high regain. Such fabrics have good moisture absorption and heat generation or warm-keeping functions, but poor quick-drying functions; or, knitted clothing with moisture absorption and quick-drying functions in summer is generally prepared by selecting chemical fiber filaments with special cross-sections, fabric structure design with unequal hydrophilic and hydrophobic effects on the inner and outer layers of the fabric, and unidirectional moisture conduction finishing. The quick-drying functional fabrics are mainly hydrophobic chemical fiber filaments. Such fabrics have good quick-drying functions, but poor hygroscopicity.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0004] 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 elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The present application provides a weft knitted fabric with moisture absorption and heat generation, moisture absorption and quick drying and antibacterial functions, which is applied to sports and leisure knitted clothing.

[0006] In some embodiments, the weft-knitted fabric with both moisture absorption and heat generation and antibacterial and quick-drying functions includes a fabric body, wherein the fabric body is composed of a surface layer, a middle layer and an inner layer, the surface layer and the inner layer are made of fiber blended yarn with moisture absorption and heat generation functions, and are woven into single-sided loops by syringe needles and dial needles configured with rib needles, respectively; the middle layer is made of chemical fiber filaments with moisture conduction and quick-drying functions, and are alternately arranged with collection loops and floating lines by syringe needles and dial needles configured with rib needles.

[0007] Optionally, the fiber blended yarn with moisture absorption and heat generation function is a blended yarn of warm ginger fiber and combed cotton.

[0008] Optionally, the blending ratio of the warm ginger fiber and the combed cotton is 30:70.

[0009] Optionally, the fineness of the blended yarn is 30-50S.

[0010] Optionally, the chemical fiber filament with moisture-conducting and quick-drying function is a modified polyester filament.

[0011] Optionally, the modified polyester filament has a fineness specification of 75D / 72F.

[0012] Optionally, the minimum pattern cycle of the fabric body is 2 vertical rows x 6 knitting rows for each of the cylinder needle and the dial needle.

[0013] The weft knitted fabric with both moisture absorption, heat generation and antibacterial quick-drying functions provided by the embodiments of the present disclosure can achieve the following technical effects:

[0014] First, it has the functions of moisture absorption, heat generation and quick drying: it adopts a three-layer ribbed composite fabric structure design. The surface and inner layers are both made of modified cellulose warm ginger fiber and combed cotton blended yarn, which are formed into a flat surface through a single-sided loop coil configured by rib needles. The blending ratio of warm ginger fiber and combed cotton is 30 / 70. Since warm ginger fiber comes from the herb ginger in nature, warm ginger fiber contains ginger active ingredients such as gingerol in ginger. 30% of warm ginger fiber in the blended yarn can absorb moisture from the body surface and the outside world and convert it into heat energy, providing moisture absorption, heat generation and warmth retention effects; the middle layer is made of modified polyester fiber, which is made of a syringe needle configured by a rib needle. The needle-dial needles, needle-dial needles, warp-tucks and floating threads are alternately arranged to form a moisture-conducting and moisture-dissipating layer. The modified polyester fiber is grafted with hydrophilic groups on the polyethylene terephthalate polymer chain and adopts a Y-shaped cross-section and a micro-groove physical morphology structure. Therefore, it has moisture absorption, moisture conduction and quick-drying properties. The middle layer of syringe needles, needle-dial needles, warp-tucks and floating threads are alternately arranged. The moisture of the inner layer of the fabric is conducted out through the middle layer of warp-tuck suspended arc structure and transferred to the surface layer of the fabric along the thickness direction of the fabric. The middle layer of floating thread structure can diffuse the moisture absorbed from the inner layer of the fabric in the middle layer of the fabric, increase the force of moisture transmission along the thickness direction, and effectively enhance the quick-drying function of the fabric.

[0015] Second, it has excellent antibacterial and antimicrobial functions: the surface and inner layers of warm ginger fiber blended yarns, as well as the middle layer of chemical fiber filaments, all have excellent antibacterial and antimicrobial functions. The ginger in warm ginger fiber contains natural antibacterial ingredients, and the textiles prepared from it have certain antibacterial capabilities, which can reduce the problems of odor and mites; the modified polyester fiber has good antibacterial properties due to the grafted hydrophilic groups, and the excellent moisture absorption and quick-drying properties of the fiber create a dry environment where bacteria are not easy to reproduce, making the modified polyester fiber have antibacterial and antibacterial effects.
