Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and in particular relates to a one-way moisture-conducting and cool air layer fabric. Background Art

[0002] The air layer fabric with three-layer sandwich structure usually has skin-friendly and comfortable fiber layers on the surface and inner layer, good wrinkle resistance and easy care characteristics, which effectively improves the texture of the fabric and is often used in weft knitted fabrics such as summer T-shirts, short sleeves or base shirts. However, conventional air layer fabrics do not have a unilateral moisture conduction function. The inner and outer layers are hydrophilic fibers, which can easily lock sweat inside when it is discharged to the outer layer and cannot be completely discharged, or the middle shell silk layer is too fluffy, resulting in poor water transport effect, blocking sweat and preventing it from being discharged in time. In hot environments or when sweating during exercise, the inner layer is saturated with moisture, and sweat cannot be discharged. The clothes stick to the body or are wet when they touch the body, which is extremely uncomfortable.

[0003] Some researchers have applied a unidirectional moisture-conducting printed layer on the inner layer of the air layer to make the fabric have a unidirectional moisture-conducting effect. However, the unidirectional moisture-conducting printed layer used has poor comfort when in contact with the skin and poor water washability, and cannot take into account both wearing comfort and functional permanence while achieving the function.

[0004] Therefore, based on this, the technical solution of the present utility model is proposed. Utility Model Content

[0005] The utility model provides a one-way moisture-conducting and cool air layer fabric, so as to solve the drawbacks of the air layer fabric in the prior art that has no one-way moisture-conducting function or has poor water washing resistance, thereby meeting the market demand for sports T-shirts.

[0006] The utility model provides a one-way moisture-conducting and cooling air layer fabric, which comprises a fabric surface layer, a fabric middle layer and a one-way moisture-conducting and cooling layer in sequence.

[0007] Preferably, the fabric surface layer is a hydrophilic staple yarn layer.

[0008] Preferably, the hydrophilic staple yarn layer is modal staple hydrophilic fiber, lyocell staple hydrophilic fiber, viscose staple hydrophilic fiber, cotton staple hydrophilic fiber or other hydrophilic fiber blended yarns, all of which are commercially available.

[0009] Preferably, the fabric middle layer is a spandex filament yarn layer purchased from Hyosung Spandex.

[0010] Preferably, the one-way moisture-conducting cooling layer is a hydrophobic skin-friendly layer.

[0011] Preferably, the hydrophobic skin-friendly layer is a nylon yarn layer fully wrapped with a nano-membrane modified by low-temperature plasma and grafted with polytetrafluoroethylene, which has hydrophobicity and permanent water-resistant effect. The fabric layer was purchased from Zhejiang Kangjiesi New Material Technology Co., Ltd., and the yarn name is WaterPass.

[0012] Preferably, the one-way moisture-conducting and cooling air layer fabric forms a wetting gradient from the one-way moisture-conducting and cooling layer to the fabric surface layer, so as to achieve rapid conduction of sweat and moisture from the one-way moisture-conducting and cooling layer to the fabric surface layer.

[0013] Preferably, the fabric surface layer has a hairiness structure, and the hairiness extends to the yarn gaps of the unidirectional moisture-conducting and cooling layer.

[0014] The beneficial effects of the utility model are:

[0015] The one-way moisture-conducting and cool air layer fabric described in the utility model adopts the nylon filament yarn of the fully wrapped nano-membrane technology of low-temperature plasma modification and polytetrafluoroethylene grafting, which has a permanent hydrophobic effect, and this technology does not affect the advantages of nylon itself such as softness, wear resistance, good elasticity, and natural coolness brought by large specific heat; modal staple hydrophilic fiber and the like are also used as the surface hydrophilic layer, which has excellent softness and hygroscopicity, and can quickly absorb moisture and lock water. The inner nylon layer with hydrophobic function is combined with the surface hydrophilic layer with hydrophilic effect to form a wetting gradient, so that the sweat and moisture generated by the skin are quickly conducted from the one-way moisture-conducting and cool feeling layer to the surface layer, and at the same time, the moisture of the outer layer is difficult to reversely penetrate to the inner layer, and the water molecule flow is controlled in a hot and humid environment to achieve one-way moisture conduction, so that the skin-friendly side is always kept dry and cool, providing a comfortable microenvironment for the human body, and at the same time, it is softer, skin-friendly, and cool when worn, meeting the functional requirements of sports T-shirts or sports base shirts.

[0016] Furthermore, the innermost layer is a hydrophobic layer, and the surface layer is a hydrophilic fiber. Considering the flatness of the actual single-sided color effect, a separate structure is adopted, connected in the middle with spandex yarn, and the short fiber hydrophilic material on the surface has fluff and can extend to the pores of the hydrophobic yarn on the back side, thereby producing a unidirectional moisture conduction effect due to the kinetic potential energy difference between the front and back sides, and can effectively prevent sweat back-osmosis.

[0025] Example 1

[0026] refer to Figure 1The utility model provides a one-way moisture-conducting and cooling air layer fabric, which includes, from outside to inside (the fabric layer in contact with the skin is the inner layer, and the fabric layer in contact with the outside is the surface layer), a fabric surface layer 1, a fabric middle layer 2, and a one-way moisture-conducting and cooling layer 3. The middle fabric layer 2 is a spandex filament yarn layer, which connects the fabric surface layer 1 and the one-way moisture-conducting and cooling layer 3, and is located between the fabric surface layer 1 and the one-way moisture-conducting and cooling layer 3.

[0027] In the one-way moisture-conducting and cooling air layer fabric, the fabric surface layer 1 is a staple yarn layer woven from hydrophilic modal staple yarns, and modal has good softness, comfort, moisture absorption and air permeability, and can quickly absorb sweat and moisture. The one-way moisture-conducting and cooling layer 3 is a nylon filament yarn layer using low-temperature plasma modified and polytetrafluoroethylene grafted fully wrapped nano-membrane technology, which has a permanent hydrophobic effect and permanent water-resistant function.

[0028] In the one-way moisture-conducting and cooling air layer fabric, the fabric surface layer 1 is the side away from the skin, the one-way moisture-conducting and cooling layer 3 is the side of the fabric that is in direct contact with the skin, the fabric surface layer 1 and the one-way moisture-conducting and cooling layer 3 are connected through the fabric middle layer 2, and a wetting gradient is formed between the inner and outer layers of the fabric, so that the inner sweat and moisture of the one-way moisture-conducting and cooling layer 3 are quickly conducted to the fabric surface layer 1, and are absorbed and locked by the modal staple fiber layer. At the same time, it is difficult for the moisture of the surface layer 1 to penetrate back to the one-way moisture-conducting and cooling layer 3, so that the flow direction of water molecules is controlled in a hot and humid environment.

[0029] In the one-way moisture-conducting and cooling air layer fabric, the one-way moisture-conducting and cooling layer 3 quickly diffuses sweat and moisture when it penetrates into the fabric surface layer 1 (hydrophilic modal staple fiber surface layer), accelerates the evaporation rate of sweat and moisture, and enables the fabric to simultaneously achieve the one-way moisture-conducting and moisture-absorbing and quick-drying functions. The one-way moisture-conducting and cooling layer 3 adopts nylon filaments, which have relatively large specific heat and are good cooling yarns, and realize the function of instant cooling when contacted. The one-way moisture-conducting and cooling layer 3 continuously conducts skin sweat and moisture to the fabric surface layer 1, and takes away heat when sweat and moisture are conducted, so that the skin-friendly side always remains dry and cool, providing a comfortable microenvironment for the human body.

[0030] In the one-way moisture-conducting and cooling air layer fabric, the spandex layer of the fabric middle layer 2 is obtained by synchronously weaving the spandex yarn with the modal staple yarn of the fabric surface layer 1 and the nylon filament yarn of the one-way moisture-conducting and cooling layer 3, and adopting the full-food spandex weaving method, the spandex yarn is wrapped under the modal staple yarn and on the nylon filament, and the fabric middle layer 2 (spandex layer) is formed between the fabric surface layer 1 and the one-way moisture-conducting and cooling layer 3. The spandex layer has good elasticity, so that the fabric can achieve a four-way stretch effect.

[0031] In the one-way moisture-conducting and cooling air layer fabric, the fabric surface layer 1 is made of modal staple fibers and has soft and comfortable properties, the spandex layer of the middle fabric layer 2 has good elasticity, and the one-way moisture-conducting and cooling layer 3 is made of nylon filaments, which are smooth, soft and wear-resistant. The combination of the three forms a one-way moisture-conducting and cooling air layer fabric that can achieve functions such as one-way moisture conduction, moisture absorption and quick drying, and a cool feeling, and is more suitable for wearing during exercise or in a hot environment, meeting the functional requirements of sports T-shirts or sports base shirts.
