Description

Technical Field

[0001] The utility model belongs to the technical field of knitted fabrics, and in particular relates to a single-sided weft-knitted fabric with the functions of moisture absorption, heat generation, antibacterial and antimicrobial inhibition, which is suitable for knitted clothing fabrics worn close to the skin in autumn and winter. Background Art

[0002] With the advancement of science and technology, people's daily life tastes have been improved, health awareness has been continuously strengthened, and more demands have been made on the comfort and functionality of textiles. Comfortable and healthy functional textiles are gradually becoming the theme and fashion of development.

[0003] Hygroscopic heat generation is the energy conversion and change caused by the interaction between water and fabric. The hygroscopic material in the fabric absorbs the moisture emitted by the human body or the moisture in the air. The water molecules are combined with the fabric in the form of hydrogen bonds. The kinetic energy of the water molecules is converted into heat energy, or the water molecules release energy due to liquefaction. Therefore, using hygroscopic heat generation materials to improve the wearing comfort of clothing has received more and more attention.

[0004] Existing hygroscopic and heat-generating knitted fabrics usually use chemical fiber modified hygroscopic and heat-generating fibers to prepare double-layer structure knitted fabrics. Common hygroscopic and heat-generating fibers include sub-acrylate fibers, modified polyacrylic fibers, ultra-fine denier acrylic fibers, modified acrylic fibers, modified viscose, etc. For example, Chinese utility model patent CN211921835U discloses a one-way moisture-conducting, moisture-absorbing and heat-generating fabric and clothing, which uses polypropylene as the moisture-conducting layer, heating yarn + elastic yarn as the moisture-absorbing and heat-generating layer, and is prepared through a double-sided weft-knitted double-layer structure. Since the fabric contains a certain proportion of hydrophobic polypropylene, the one-way moisture-conducting function can be improved, but the overall hygroscopicity of the fabric is not high, which affects the improvement of the moisture-absorbing and heat-generating function; for another example, Chinese utility model patent CN212335447U discloses a moisture-absorbing and heat-generating functional fabric, which uses moisture-absorbing and heat-generating fiber Porel + spandex, moisture-absorbing and heat-generating acrylic / Modal blended yarn, and is interwoven through a rib-type double-sided composite tissue. It has good moisture-absorbing and heat-generating properties and is suitable for knitted underwear; for another example, Chinese utility model patent CN211079501U discloses a moisture-absorbing and heat-generating knitted underwear fabric, which uses ultrafine acrylic / highly hygroscopic viscose blended yarn, 40D Spandex bare yarn, polyester textured yarn, combed cotton yarn, are prepared by a double-sided quilted structure design formed by gathering, looping, and not weaving, and have good moisture absorption and heat generation properties, and are suitable for knitting underwear; for example, Chinese utility model patent CN215404820U discloses a knitted fabric containing warm ginger fiber, which is a double-sided air layer fabric, the inner layer is woven with warm ginger / cotton blended yarn, the outer layer is woven with cotton / viscose blended yarn, and the middle layer is connected with spandex. The fabric has shearing on both sides and has moisture absorption and perspiration function, but the above fabrics have no other functions such as antibacterial and antibacterial; for example, Chinese utility model patent CN219010604U discloses a moisture-absorbing and heat-generating wool knitted fabric, which is prepared by twisting acrylic-based moisture-absorbing and heat-generating fibers with wool, and then compounded with a warm fabric layer prepared by twisting cashmere yarn and polylactic acid aerogel yarn to give the fabric antibacterial function. The fabric has many layers and the preparation process is complicated.

[0005] In summary, although the existing one-piece woven moisture-absorbing and heat-generating knitted fabrics generally have good moisture-absorbing and heat-generating functions, they lack the composite functions of moisture conduction and antibacterial and antimicrobial properties.

[0017] Compared with the prior art, the single-sided weft-knitted fabric with both moisture absorption, heat generation and antibacterial and antibacterial functions provided by the utility model has the following advantages:

[0018] (1) It has both hygroscopic and heat-generating and antibacterial functions: the fabric adopts a single-sided three-thread padding weft knitted structure, in which the padding yarn of the hygroscopic and heat-generating inner layer and the veil of the hygroscopic and heat-generating outer layer adopt warm ginger fiber blended yarn with good hygroscopic and heat-generating and antibacterial functions, which can make the fabric have good hygroscopic and heat-generating and antibacterial functions; the ground yarn of the hygroscopic and moisture-conducting layer adopts modified polyester supercool filament with good hygroscopicity, moisture conductivity and antibacterial functions, so that the overall hygroscopic and heat-generating and antibacterial functions of the fabric are remarkable; at the same time, the difference in moisture regain of supercool filament and warm ginger fiber blended yarn is used to form a differential moisture absorption gradient between the two layers of fabric interwoven with the ground yarn and the veil, which is conducive to transferring excess moisture of the human body from the inner layer of the fabric to the outer layer of the fabric. Therefore, the fabric also has the characteristics of moisture conduction and keeping the human body surface skin dry.

[0019] (2) Soft touch, with a warm effect: On the reverse side of the three-thread padding fabric, the padding yarn layer and part of the ground yarn layer can directly contact the human skin surface. Since the padding yarn is thick and is in the form of floating yarn on the reverse side of the fabric, and the ground yarn is thinner and is in the form of a suspended arc on the reverse side of the fabric, the majority of the padding yarn is in contact with the human skin. The thicker padding yarn is lightly raised after finishing to form a soft touch layer. The fine velvet on the surface of the inner layer of the fabric not only effectively improves the softness of the touch, but also the fine velvet can store still air. Without increasing the mass of the fabric too much, it effectively improves the warmth of the fabric, making it suitable for knitted garments worn close to the skin in autumn and winter.

[0020] (3) The fabric is light and thin: the weft-knitted single-sided three-thread plating structure uses 16S, 120D, and 32S yarns for the lining yarn, ground yarn, and veil yarn respectively, and the weight per square meter is controlled to be 300g / m 2 The machine with a gauge of 24 needles is used for knitting, and the fabric is thin and light overall. The ratio of tuck and float in the lining yarn is 1:1, and the fabric is relatively tight overall.

[0021] (4) Simple preparation process: The weft-knitted fabric, which consists of a soft touch layer, a moisture-absorbing and heat-generating inner layer, a moisture-absorbing and moisture-conducting layer, and a moisture-absorbing and heat-generating outer layer, is woven integrally from a weft-knitted single-sided padding tissue. During the post-finishing process, only the padding yarn needs to be slightly raised, and the overall preparation process is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 is a schematic diagram of the appearance of a single-sided weft-knitted fabric having both moisture absorption, heat generation and antibacterial and antibacterial functions in an embodiment of the utility model; and

[0023] Figure 2 It is a coil structure diagram of a single-sided weft-knitted fabric having both moisture absorption, heat generation and antibacterial and antibacterial functions in an embodiment of the utility model. DETAILED DESCRIPTION

[0024] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0025] like Figure 1 As shown, the single-sided weft-knitted fabric with both hygroscopic and heat-generating and antibacterial and antimicrobial functions comprises a soft touch layer 1, a hygroscopic and heat-generating inner layer 2, a hygroscopic and moisture-conducting layer 3 and a hygroscopic and heat-generating outer layer 4 which are arranged from inside to outside according to the wearing effect of the clothing.

[0026] The above-mentioned single-sided weft-knitted fabric is made of Figure 2 The weft-knitted single-sided three-thread padding structure containing padding yarn 5, ground yarn 6 and face yarn 7 is prepared by brushing. Specifically, the soft touch layer 1 is formed by brushing the floating yarn of the padding yarn 5, and the appearance is thin fluff, forming a suede surface; the hygroscopic and heat-generating inner layer 2 is formed by warp knitting the padding yarn 5, and the appearance is tucked loops and short-line floating yarns that are not raised; the hygroscopic and moisture-conducting layer 3 is formed by warp knitting the ground yarn 6, and the appearance is a plain needle coil; the hygroscopic and heat-generating outer layer 4 is formed by warp knitting the face yarn 7, and the appearance is a plain needle coil. In this embodiment, the ratio of the tucked loops and floating yarns of the padding yarn 5 in the weft-knitted single-sided three-thread padding structure is one or more of 1:1, 1:2, and 1:3, preferably 1:1.

[0027] Both the padding yarn 5 and the veil 7 are blended yarns of modified cellulose fiber with hygroscopic heat generation and antibacterial and bacteriostatic functions and cellulose fiber with a high moisture regain, wherein the modified cellulose fiber is warm ginger fiber, and the cellulose fiber is one or more of viscose fiber and cotton fiber. In this embodiment, the blended yarn is prepared by a siro compact spinning process with a mass blending ratio of 30:70 between warm ginger fiber and viscose fiber; the fineness of the blended yarn used as the padding yarn 5 is 16S, and the twist is 610 twists / m; the fineness of the blended yarn used as the veil 7 is 32S, and the twist is 840 twists / m.

[0028] Warm ginger fiber is a ginger extract made by extracting the effective ingredients from fresh ginger, concentrating and drying it, grinding it into nano-scale powder, and blending the extract with wood pulp to make a modified viscose, which has hygroscopic heat generation and antibacterial and antibacterial functions. In order to reduce costs, warm ginger fiber is blended with cotton, viscose and other cellulose fibers in a certain proportion to make warm ginger fiber blended yarn, which also has good hygroscopic heat generation and antibacterial and antibacterial functions.

[0029] The ground yarn 6 is a modified polyester fiber with moisture absorption, quick drying and antibacterial and bacteriostatic functions. In this embodiment, the ground yarn 6 is made of modified polyester supercool filament with a specification of 120D / 96F.

[0030] The modified polyester supercool fiber is grafted with hydrophilic groups on the polyethylene terephthalate polymer chain, and adopts a Y-shaped cross-section and micro-groove physical morphology structure, which makes it have excellent moisture absorption, moisture conduction and quick-drying properties. Because the grafted hydrophilic groups have good antibacterial properties, the fiber does not contain any heavy metals such as silver. In addition, the fiber has excellent moisture absorption and quick-drying properties, creating a dry environment where bacteria are not easy to reproduce, and has a certain antibacterial effect.

[0031] In this embodiment, the manufacturing method of the single-sided weft-knitted fabric having both moisture absorption, heat generation and antibacterial and antibacterial functions is as follows:

[0032] Warm ginger fiber and viscose fiber were selected in a mass ratio of 30:70, and the siro compact spinning process was used to prepare blended yarns with a fineness of 16S and a twist of 610 twists / m as the lining yarn, and a blended yarn with a fineness of 32S and a twist of 840 twists / m as the veil; modified polyester supercool filament with a specification of 120D / 96F was selected as the ground yarn.

[0033] It is woven on a single-sided three-wire cushion circular knitting machine with a cylinder diameter of 30 inches and a machine gauge of 24G. The ratio of the cushion yarn's loops to the floats is 1:1.

[0034] The raw fabric after the machine is made into a smooth raw fabric through the processes of mixing cylinder → pre-setting → pre-treatment → two-bath dyeing (one bath supercool, one bath warm ginger / viscose) → soap washing → color fixing → drying → inner layer napping → drying → setting. The width of the smooth raw fabric is 155cm, and the weight per square meter is 290g / m 2 .

[0035] In summary, the warm ginger fiber blended yarn with moisture absorption, heat generation, antibacterial and antibacterial functions was selected, combined with the modified polyester supercool fiber with moisture absorption, quick drying and antibacterial and antibacterial functions, and the fabric was prepared through a knitted one-piece structure design to achieve good moisture absorption, heat generation, antibacterial and antibacterial effects, and the preparation process is simple.

[0036] The above implementation modes are preferred examples of the present invention and are not intended to limit the protection scope of the present invention.
