Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description is given of the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1, a fabric with overall structure, a waterproof, oil-proof and breathable fabric, comprising: surface layer, intermediate layer and inlayer, wherein: the surface layer is waterproof oil-proof layer 1, the intermediate level is ventilative water absorption layer 2, the inlayer is basic cloth 3, waterproof oil-proof layer 1 includes canvas layer 102, canvas layer 102 upper surface has micropore oil resistance film 101, ventilative water absorption layer 2 includes water absorption layer 202, the upper surface of water absorption layer 202 is provided with first ventilative layer 201, the lower surface of water absorption layer 202 is provided with second ventilative layer 203.

The canvas has good waterproof performance, and the canvas is arranged on the surface layer of the fabric, so that the wear resistance can be maximized while the waterproof performance of the canvas is utilized. Since the waterproof performance of the canvas can not completely isolate the water from the fabric, it is considered that when most of the water is isolated from the fabric, a small amount of water still enters, at this time, the water-absorbing layer 202 needs to be arranged in the fabric layer, and a good ventilation environment is needed after the hydrophilic material absorbs water, so that the hydrophilic material can be quickly restored to a dry state after the water absorption is finished, and the material in the fabric layer is prevented from mildewing, so that the ventilation fabric layer with good ventilation performance is arranged on the upper layer and the lower layer of the water-absorbing layer 202 to achieve the purpose.

Further, in a preferred embodiment of the present application, referring to fig. 2, the oil-resistant film 101 has micropores, the oil-resistant film 101 is mainly made of fluorocarbon copolymer, and the upper surface of the canvas layer 102 is covered with the oil-resistant film 101. The perfluorocarbon chain with extremely low surface energy is stretched to the outside as if it were standing on the surface of a polymer molecule like pig hair due to its strong rigidity and poor flexibility. Therefore, when the liquid drips on the surface of the fabric, the liquid is shielded by the perfluorocarbon chain layer, and excellent waterproof and oil-proof effects are exerted, so that the fluorocarbon copolymer has excellent waterproof and oil-proof effects on all fiber fabrics.

Further, in a preferred embodiment of the present application, the first breathable layer 201 is a cotton fabric with a pore structure, and a fabric such as fine spinning may be used. Because cotton surface fabric ventilates moisture absorption effect is good, first ventilative layer 201 sets up in the upper surface of layer 202 that absorbs water, can absorb the moisture that carries in the air in ventilative, before reaching the layer 202 that absorbs water, the moisture in the air has permeated each surface fabric that the hydroscopicity is good for the moisture in the air further reduces, improves the efficiency of absorbing water. In this process, the air permeability is mainly used, so that the cotton fabric with the pore structure can maintain good air permeability to a great extent.

Further, in a preferred embodiment of the present application, the second breathable layer 203 is a PE polymer breathable film. The PE high polymer breathable film is characterized in that a functional inorganic substance is uniformly added and mixed into a polyolefin raw material, so that a product generates air holes due to high-power stretching in the film forming process, and the PE high polymer breathable film has the breathable and moisture-guiding functions. The second breathable layer 203 is disposed on the lower surface of the water absorbent layer 202, and is a breathable layer closer to the skin. The PE polymer breathable film has the functions of ventilation and moisture conduction, and can lead out hot air which is required to be exhausted by a human body, and part of sweat generated by the human body can be absorbed by the base cloth 3, so that the requirement of the PE polymer breathable film on water absorption is not high, and the ventilation is considered seriously.

Further, in a preferred embodiment of the present application, the water absorbing layer 202 is a hydrophilic nonwoven material, and is formed by crisscross combination. Fig. 3 shows a water absorbing layer 202 arranged between a first air permeable layer 201 and a second air permeable layer 203, wherein the water absorbing layer 202 is made of hydrophilic non-woven fabric material, and the hydrophilic non-woven fabric is prepared by adding hydrophilic agent in the non-woven fabric production process, so that the water absorbing layer has strong water absorption, low cost benefit and wide application range. Since the water-absorbent layer 202 needs strong water absorption while maintaining air permeability, the structure of the water-absorbent layer 202 is arranged to be spaced apart from each other in the longitudinal direction and the transverse direction by a cross-type combination. The structure is clearly shown in fig. 3, which leaves a closely packed rectangular tessellation that is breathable. The combination mode of the material of the hydrophilic non-woven fabric and the crisscross can well reflect water absorption, absorb a small amount of water vapor which is not totally blocked by the outer surface from outside, and absorb the scattered sweat on the inner side contacting with the body, so that good ventilation and water prevention effects are realized.

Further, in a preferred embodiment of the present application, the base fabric 3 is mainly made of oxford fabric. The base cloth 3 and the second air-permeable layer 203 are bonded by the second bonding layer 5 of the gauze. The base fabric 3 is the innermost layer of the fabric, most of the base fabric needs to be in direct contact with skin in the use process, the oxford fabric is soft, good in air permeability and good in hygroscopicity, sweat on the surface of the skin can be absorbed quickly, and good comfort is provided.

Further, in a preferred embodiment of the present application, the upper surface of the first air permeable layer 201 and the lower surface of the canvas layer 102 are adhered by the first adhesive layer 4 in a dot-like or stripe-like glue application manner. The upper surface of the base cloth 3 and the lower surface of the second air-permeable layer 203 are adhered in a dot-like or strip-like glue-coated manner by the second adhesive layer 5. The air permeability of the adhesive surface can be maintained to the greatest extent by means of dot-shaped or strip-shaped adhesive coating, large-area adhesive coating is reduced, and the small-area dot-shaped adhesive coating effect is better.

Further, in a preferred embodiment of the present application, the adhesive layers are all gauze fabrics, and the thickness of the adhesive layer is 0.1-0.3mm. The coarse degree of the bonding surface is increased through the gauze structure, the bonding can be more compact in the process of combining the upper surface layer and the lower surface layer, the bonding effect is enhanced, meanwhile, the air permeability of the surface is kept, so that the thickness of the bonding layer is 0.1mm-0.3mm, the thickness of the bonding layer is 0.1mm and is preferably set forth based on the technology for manufacturing the adhesive coating surface, the adhesive surface with the thickness of 0.1mm is ideal thickness, but technical limitations and deviation exist in the implementation process, the requirement of combining the air permeability is met, the thickness of the bonding layer is not more than 0.3mm, the maximum range of the thickness of a general high-definition gauze is about 0.23mm, and the thickness interval of 0.1mm-0.3mm is adopted in consideration of the possible deviation in manufacturing, and the application is preferably 0.2mm in combination with the actual manufacturing condition.

The present utility model is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present utility model.
