Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a one-way moisture-conducting warp knitted fabric. Background Art

[0002] As consumers' living standards continue to improve, their functional requirements for consumer products are also increasing, including clothing. In the hot summer or when exercising, people sweat easily. A key development direction for clothing fabrics is how to quickly remove and evaporate sweat to prevent discomfort caused by excessive sweat.

[0003] At present, the research on one-way moisture-conducting fabrics mainly focuses on weft knitted fabrics, woven fabrics or using a combination of hydrophobic and hydrophilic yarns to make the front and back of the fabric have different moisture-conducting capabilities to form a one-way moisture-conducting fabric. For example:

[0004] Patent document CN2024325676U discloses "A one-way moisture-conducting weft-knitted fabric" and reports that the front of the fabric is made up of moisture-conducting yarn coils and moisture-absorbing yarn coils at certain intervals, and the back of the fabric is made up of all moisture-conducting yarn coils. The moisture concentration gradient between the inner and outer layers of the fabric is maintained by the multi-microporous yarn used, thereby ensuring the one-way conduction of moisture.

[0005] Patent document CN110184730A discloses "Unidirectional moisture-conducting single-sided knitted fabric and its preparation process", which reports that drainage holes and drainage grooves are formed on the front side of the jersey plain weave and on the back side of the terry structure through weaving needle arrangement and triangle sorting process, and the unidirectional moisture-conducting function can be achieved without adding water-repellent additives in the finishing stage.

[0006] Patent document CN110117870A discloses "A unidirectional moisture-conducting composite fabric and its manufacturing method", reporting that through a special weft knitting process, the inner surface of the fabric has a protrusion with a small F number. When it comes into contact with sweat, the loose pores of the protrusion will absorb the sweat and use the siphon effect to quickly discharge the sweat to the diffusion surface of the fabric.

[0007] Patent document CN205529306U discloses "A one-way moisture-conducting functional fabric" and reports a weft-knitted fabric including a close-fitting layer and a surface layer. The close-fitting layer is woven with hydrophobic polypropylene fibers and hydrophilic fibers, wherein the area woven with the hydrophobic polypropylene fibers accounts for 75% of the total area of ​​the close-fitting layer and the area woven with the hydrophilic fibers accounts for 25% of the total area of ​​the close-fitting layer. When the close-fitting layer sweats violently, the hydrophobic polypropylene fibers perform a wicking effect to expel sweat while the hydrophilic fibers absorb sweat. The fabric will not stick to the skin, giving the wearer a comfortable experience.

[0008] Patent document CN 207452371U discloses "A knitted fabric with unidirectional moisture conduction function" and reports a weft-knitted fabric woven from several front-side minimum pattern loops. The 1st and 4th horizontal paths are woven with high moisture conduction fibers as the base yarn, and the 2nd, 3rd, 5th, and 6th horizontal paths are woven with fibers with poor moisture conduction properties, such as cotton yarn, as the surface yarn, so that the fabric has the effect of quickly conducting sweat out of the body and evaporating it quickly.

[0009] Patent CN209955444U discloses a "unidirectional moisture-conducting fabric structure" and describes a fabric structure comprising, from top to bottom, a unidirectional moisture-conducting layer, a flow-conducting hydrophobic layer, a waterproof layer, and a breathable layer. The unidirectional moisture-conducting layer absorbs sweat, while the flow-conducting hydrophobic layer prevents liquid from leaking and rapidly absorbs water. Any small amount of liquid that passes through the waterproof layer is discharged into the air through the breathable layer, effectively blocking liquid.

[0010] In summary, the fabrics currently available on the market with the ability to be cut at will still have high requirements for yarn. However, precisely because they do not require cutting and can be worn directly, they are prone to embarrassing situations such as slipping and falling off. Summary of the Invention

[0011] In order to solve the above technical problems, the present invention provides a unidirectional moisture-conducting warp knitted fabric, which utilizes the mutual coverage and coil structure between yarns and the difference in water conductivity of the yarns to form good unidirectional moisture-conducting performance.

[0012] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0013] A one-way moisture-conducting warp-knitted fabric comprises a fabric body, wherein the fabric body is woven from at least two non-elastic yarns Y1 and Y2 through three or more combing bars to form an extension line layer, an intermediate layer and a coil column layer in sequence from the bottom surface of the fabric body to the surface of the fabric body, wherein the extension line layer is a skin-contacting surface, and the coil column layer is a clothing surface; the non-elastic yarn Y1 forms the extension line layer in the form of floating lines and forms coils on the coil column layer; the non-elastic yarn Y2 forms the intermediate layer in the form of floating lines and forms coils in the coil column layer; the extension lines of the non-elastic yarn Y1 overlap the extension lines of the non-elastic yarn Y2; the non-elastic yarn Y2 covers the non-elastic yarn Y1, and the non-elastic yarn Y2 and the non-elastic yarn Y1 have different water-conducting capabilities.

[0014] As a further improvement, the non-elastic yarn Y1 is used for weaving the comb bar GB1 with the same direction of warp and diagonal full weaving to form an extension line layer.

[0015] As a further improvement, the non-elastic yarn Y2 is used for the combing bars GB2 and GB3 to weave a middle layer with a mutually reversed warp satin structure and in an opposite threading manner.

[0016] As a further improvement, the extension line formed by the non-elastic yarn Y1 and the non-elastic yarn Y2 is ≤ 6 needles, preferably 4 needles.

[0017] As a further improvement, the denier of the non-elastic yarn Y1 is selected between 20D and 75D, and the fiber count is selected between 12F and 36F; the denier of the non-elastic yarn Y2 is selected between 30D and 75D, and the fiber count is selected between 36F and 144F; the water conductivity LP2:LP1 of the non-elastic yarn Y2 and the non-elastic yarn Y1 is greater than 1.5.

[0018] As a further improvement, the non-elastic yarn Y1 and the non-elastic yarn Y2 are both chemical fiber filaments.

[0019] As a further improvement, the fabric body is provided with invisible holes, which appear as regular-shaped breathable holes when the fabric body is stretched.

[0020] As a further improvement, the fabric body is provided with decorative buds.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] The yarns with different water conductivity are woven to form the extension line layer, the middle layer and the coil layer respectively, and an overlapping coil structure is formed in the coil layer, i.e. the clothing surface, and the yarns are covered with each other, i.e. the non-elastic yarn Y1 with smaller water conductivity in the extension line layer covers the non-elastic yarn Y2 with larger water conductivity. Overall, the non-elastic yarn Y2 with larger water conductivity covers the non-elastic yarn Y1 with smaller water conductivity. In addition, the clothing surface adopts the two yarns to form loops separately, so that the water conductivity of the extension line layer is smaller than that of the coil layer. After the extension line layer, i.e. the skin-contacting surface, absorbs water, the moisture can be quickly transferred to the coil layer, i.e. the clothing surface, to form good unidirectional moisture conduction performance. According to the GB / T21655.2 method, its water conductivity OWTC is >100%. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, removable connections, or integral connections. They may refer to mechanical connections or electrical connections. They may refer to direct connections or indirect connections through an intermediary, and they may refer to internal communication between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0030] refer to Figure 1-4As shown, a one-way moisture-conducting warp-knitted fabric includes a fabric body, wherein the fabric body is woven with at least two non-elastic yarns Y1 and non-elastic yarns Y2 through more than three combs to form an extension line layer 1, an intermediate layer 2 and a coil layer 3 in sequence from the bottom surface of the fabric body to the surface of the fabric body, wherein the extension line layer 1 is the skin-contacting surface, and the coil layer 3 is the clothing surface; the non-elastic yarn Y1 forms the extension line layer 1 in the form of floating lines and forms coils on the coil layer 3; the non-elastic yarn Y2 forms the intermediate layer 2 in the form of floating lines and forms coils on the coil layer 1; the extension line of the non-elastic yarn Y1 covers the extension line of the non-elastic yarn Y2; the non-elastic yarn Y2 covers the non-elastic yarn Y1, and the water-conducting capacity of the non-elastic yarn Y2 and the non-elastic yarn Y1 is different. In order to enable moisture to be quickly transferred from the skin-contacting surface to the clothing surface, the water-conducting capacity of the non-elastic yarn Y1 is set to be smaller than the water-conducting capacity of the non-elastic yarn Y2. Knitting both non-stretch yarns Y1 and Y2 in a floating yarn structure facilitates moisture transfer and interwoven coverage. The skin-contacting side has weaker water-conductivity, while the garment-facing side has stronger water-conductivity. This allows perspiration to be quickly transferred from the weaker side to the stronger side, dissipating water quickly and improving wearer comfort.

[0031] Specifically, the skin-facing stretch layer is knitted from non-elastic yarn Y1, the middle layer is knitted from non-elastic yarn Y2, and the coil layer is knitted from both non-elastic yarns Y1 and Y2. As a result, the water-conducting capacity increases in the order of the stretch layer, middle layer, and coil layer.

[0032] The non-elastic yarn Y1 is used for weaving the comb bar GB1 with the same direction of warp and diagonal full weaving to form an extension line layer.

[0033] The non-elastic yarn Y2 is used in the comb bars GB2 and GB3 to form an intermediate layer with a mutually reversed warp satin structure and in opposite yarn threading methods. For example, the comb bar GB2 adopts a one-thread-one-hole weave method, while the current comb bar GB3 adopts a one-hole-one-thread weave method; and if the comb bar GB2 adopts a one-hole-one-thread weave method, then the comb bar GB3 adopts a one-thread-one-hole weave method, and the yarn threading methods are opposite.

[0034] The extension line formed by the non-elastic yarn Y1 and the non-elastic yarn Y2 is ≤ 6 stitches, preferably 4 stitches. With this number of stitches, better yarn quantity distribution and weaving can be achieved, maintaining better water-conducting performance.

[0035] The non-elastic yarn Y1 has a denier between 20D and 75D, and a fiber count between 12F and 36F. The non-elastic yarn Y2 has a denier between 30D and 75D, and a fiber count between 36F and 144F. The water conductivity of the non-elastic yarn Y2 and non-elastic yarn Y1 is LP2:LP1>1.5. The non-elastic yarn Y2 is formed in the middle layer, and its water conductivity is greater than that of the extension yarn layer woven with the non-elastic yarn Y1, ensuring that moisture in the extension yarn layer is actively transferred to the middle layer. The coil layer, composed of the loops woven with the non-elastic yarn Y1 and Y2, has even stronger water conductivity. That is, the coil layer has a greater water conductivity than the middle layer, allowing moisture in the middle layer to be actively transferred to the coil layer, achieving differentiated unidirectional moisture transfer.

[0036] The non-elastic yarn Y1 and the non-elastic yarn Y2 are both chemical fiber filaments and are made of the same non-elastic yarn. The non-elastic yarn described in this application can be a yarn without elasticity or a yarn with very low elasticity.

[0037] The fabric body is provided with invisible holes that appear as regularly shaped ventilation holes when the fabric body is stretched. When the fabric body is not subjected to external stretching forces, the invisible holes are squeezed and hidden. However, when the fabric body is stretched by external forces, the invisible holes become visible. For example, the invisible holes can be configured to appear diamond-shaped or elliptical. When the user wears the fabric, stretching their limbs causes the fabric to stretch, revealing the invisible holes and thus improving breathability.

[0038] In addition, the fabric body is provided with decorative buds to play a decorative role.

[0039] The following is an explanation using a production example.

[0040] Three comb bars are used for weaving, namely comb bar GB1, comb bar GB2 and comb bar GB3. Comb bars GB1 and comb bars GB2 are respectively weaved with the same type of non-elastic yarn of different specifications, and comb bars GB2 and comb bars GB3 are weaved with the same type of non-elastic yarn of the same specifications.

[0041] Weaving is performed under the premise that the extension line of comb bar GB1 is greater than the extension line of comb bar GB2 and comb bar GB3. The water conductivity LP1 of the yarn selected by comb bar GB1 is less than the water conductivity LP2 of the yarn selected by comb bar GB2. The specific parameters are as follows:
