Description

Technical Field

[0001] This utility model relates to the field of outdoor fabrics, specifically a soft fabric. Background Technology

[0002] Ordinary fabrics are generally made of pure cotton, synthetic cellulose fibers, or silk, and are woven using plain weave, satin weave, or other composite weaves. While these fabrics have certain advantages in terms of comfort and crispness, they also have the following drawbacks:

[0003] The breathability and moisture-wicking properties of ordinary fabrics need improvement. While pure cotton, synthetic cellulose fibers, and silk are considered relatively breathable and absorbent materials, their perspiration-wicking ability is still insufficient to meet the higher demands of some consumers. When wearing pajamas made of these fabrics, sweat produced by the body cannot evaporate sufficiently, causing moisture to remain on the skin's surface, resulting in discomfort and even skin problems. Therefore, for those who sweat easily or live in humid climates, the perspiration-wicking properties of the fabric are particularly important for wearing comfort. Utility Model Content

[0004] To overcome the problems of poor softness and sweat-wicking performance in existing fabrics, this invention provides a soft fabric with excellent sweat-wicking properties.

[0005] The present invention adopts the following technical solution.

[0006] A soft fabric includes a skin layer, a moisture-wicking layer and a quick-drying layer arranged sequentially. The moisture-wicking layer has a moisture-wicking fleece extending into the quick-drying layer on one side near the quick-drying layer. The quick-drying layer includes multiple hydrophilic nanofibers stacked on top of each other, and multiple hydrophilic protrusions are formed on the hydrophilic nanofibers.

[0007] Preferably, the moisture-wicking layer is made of weft velvet, and the moisture-wicking layer is woven with 5.6tex moisture-wicking yarn, which is a blend of profiled polypropylene fiber and cotton fiber.

[0008] Preferably, the diameter of the hydrophilic nanofiber is 100-500 nm, the hydrophilic protrusions are arranged periodically, the distance between two adjacent hydrophilic protrusions is 10-50 μm, and the hydrophilic protrusions are spherical or ellipsoidal.

[0009] Preferably, the thickness of the skin layer is 3 mm, the thickness of the moisture-wicking layer is 5 mm, and the thickness of the quick-drying layer is 1.5 mm.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention provides a soft fabric comprising a skin layer, a moisture-wicking layer, and a quick-drying layer arranged sequentially. A moisture-wicking fleece extending into the quick-drying layer is disposed on the side of the moisture-wicking layer adjacent to the quick-drying layer. The quick-drying layer comprises multiple stacked hydrophilic nanofibers, each with multiple hydrophilic protrusions. The moisture-wicking fleece can more efficiently transfer moisture to the quick-drying layer, which quickly evaporates the moisture from the moisture-wicking layer, resulting in excellent wearing comfort. Simultaneously, the moisture-wicking fleece provides a larger contact area for the hydrophilic nanofibers, allowing the quick-drying layer to be more firmly fixed to the moisture-wicking layer.

[0016] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0017] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] A soft fabric includes a skin layer 1, a moisture-wicking layer 2, and a quick-drying layer 3 arranged sequentially. A moisture-wicking fleece 21 extending into the quick-drying layer 3 is disposed on the side of the moisture-wicking layer 2 closest to the quick-drying layer 3. The moisture-wicking fleece 21 is positioned away from the skin layer 1 and has numerous raised fibers. These fibers increase the contact area between the moisture-wicking layer and the quick-drying layer 3, thereby increasing the rate of moisture transfer to the quick-drying layer 3 and reducing the drying time of the moisture-wicking layer 2. Simultaneously, the moisture-wicking fleece 21 provides a larger contact area for the quick-drying layer 3, allowing the quick-drying layer 3 to be more firmly fixed to the moisture-wicking layer 2.

[0019] The quick-drying layer 3 includes multiple hydrophilic nanofibers 31 stacked on top of each other, and multiple hydrophilic protrusions 32 are formed on the hydrophilic nanofibers 31.

[0020] In some embodiments, the moisture-wicking layer 2 is woven with weft-pile fabric and is made of 5.6tex moisture-wicking yarn, which is a blend of profiled polypropylene fibers and cotton fibers. The profiled polypropylene fibers have numerous grooves on their surface, thereby creating a wicking effect and preventing liquid from returning to the skin layer 1, thus avoiding an unpleasant tactile experience.

[0021] In some embodiments, the diameter of the hydrophilic nanofibers 31 is 100-500 nm, the hydrophilic protrusions 32 are arranged periodically, the distance between two adjacent hydrophilic protrusions 32 is 10-50 μm, and the hydrophilic protrusions 32 are spherical or ellipsoidal.

[0022] In some embodiments, the thickness of the skin layer 1 is 3 mm, the thickness of the moisture-wicking layer 2 is 5 mm, and the thickness of the quick-drying layer 3 is 1.5 mm.

[0023] The above-mentioned soft fabric can be prepared by the following methods:

[0024] (1) Both the skin layer 1 and the moisture-wicking layer 2 are woven on a rapier loom. The fabric structure of the skin layer 1 is satin weave. The moisture-wicking layer 2 is a weft-pile weave, and its fabric structure is as follows: Figure 2 As shown, the moisture-wicking layer 2 also needs to undergo a shearing process to form moisture-wicking fleece 21.

[0025] (2) The skin layer 1 and the moisture-wicking layer 2 are bonded together using a 45-degree inclined bonding process between the warp yarns to minimize the impact of the bonding process on moisture permeability. Subsequent finishing processes include: splitting, pre-setting, singeing, enzyme treatment, pretreatment, dyeing, flat-width wetting, drying, softening and stretching, and calendering. In this finishing process, a special "five-process" technique is applied: singeing, enzyme treatment, dyeing, softening and stretching, and calendering, giving the skin layer 1 a smooth feel and improved softness, elasticity, and extensibility.

[0026] (3) Finally, a quick-drying layer was prepared. Active additives such as polyetheramine (PEA), polyethylene glycol glycidyl ether (PEGDGE), and γ-(2,3-epoxypropoxy)propyltrimethoxysilane (GPTMS) were dissolved in N,N-dimethylformamide and heated and stirred in a water bath at 50°C for 12 hours to prepare a homogeneous solution with a concentration of 14 wt%, thus obtaining the electrospinning solution. During the phase inversion process, the active additives can effectively adjust the pore size of the separation membrane and undergo a cross-linking reaction, introducing a large number of hydrophilic groups (-CH2-O-CH2-, -COOH, -Si-OH) into the membrane surface and pores, thereby endowing the modified membrane with excellent hydrophilicity. The above electrospinning solution was emitted to the side of the moisture-wicking layer 2 away from the skin layer 1 through an electrospinning machine. The electrospinning parameters were as follows: voltage 25 kV; infusion rate 3 mL / h; spinning time 5 h; receiving distance approximately 20 cm; controlled spinning environment temperature 40°C; humidity 30%. After adjusting the parameters, electrospinning can begin.

[0027] During the spinning process, polyetheramine (PEA) forms entanglements in the solution, exhibiting a certain viscosity. The solution is stretched by the electric field force under a high-voltage electrostatic field. When enough entangled molecular chains are oriented along the jet axis, they can balance the stretching force of the electric field, maintaining the continuity of the jet and thus forming hydrophilic nanofibers 31. Due to the infusion rate of 3 mL / h, some solution will not form hydrophilic nanofibers 31 and will accumulate. As the accumulated solution increases, the jet cannot maintain continuity and will break, thus periodically forming hydrophilic protrusions 32.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
