The skin-friendly and comfortable knitted fabric comprises a woven fabric body, a woven fabric raw silk layer and a high elastic raw silk layer. A fluff layer is arranged at the edge of the upper surface of the woven fabric body, a woven fabric raw silk layer is arranged on one side of the fluff layer, an elastic band is arranged on one side of the woven fabric raw silk layer, a cotton yarn layer is arranged on one side of the elastic band, and an elastic waterproof layer is arranged on one side of the cotton yarn layer. The skin-friendly and comfortable knitted fabric is conducive to improving the comfort of the fabric through the arrangement of the woven fabric raw silk layer, and the elasticity is relatively large through the arrangement of the high elastic raw silk layer, so that the fabric has better comfort.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example

[0023] Reference Figure 1-3 , a skin-friendly knitted fabric that prevents backflow after absorbing water, comprising a porous fabric layer 1 and a first adsorption layer 2 arranged on the lower side of the porous fabric layer 1, a water-absorbing core layer 3 is arranged on the lower side of the first adsorption layer 2, a second adsorption layer 4 is arranged on the lower side of the water-absorbing core layer 3, and a non-woven fabric covering layer 5 is arranged on the lower side of the second adsorption layer 4;

[0024] The water-absorbent core layer 3 includes a third adsorption layer 36 located between the first adsorption layer 2 and the second adsorption layer 4. A plurality of flow grooves 34 are evenly arranged on the third adsorption layer 36. The density of the flow grooves 34 is 300 to 500 per square meter, and the pore size of the flow grooves 34 is 0.2 mm to 0.3 mm. The flow grooves 34 are all connected to an anti-backflow channel 31. The anti-backflow channel 31 is "J"-shaped, and the placement groove 32 is spherical. The other side of the anti-backflow channel 31 is connected to the placement groove 32, and each placement groove 32 is provided with a water-absorbent ball 33.

[0025] A plurality of first through holes 21 are provided on the surface of the first adsorption layer 2 and the second adsorption layer 4, the density of the first through holes 21 is 1000 to 3000 per square meter, and the aperture of the first through holes 21 is 0.1 mm to 0.15 mm, and each first through hole 21 is connected to a plurality of groups of vertically distributed water-locking chute 23 on the circumference thereof, and the water-locking chute 23 on the first adsorption layer 2 and the water-absorbing core layer 3 are in opposite directions, so that when the fabric is placed on the front side or the back side, the water-locking chute 23 will lock the water to prevent water from overflowing.

[0026] The first adsorption layer 2, the second adsorption layer 4 and the third adsorption layer 36 are all made of ultrafine fibers. The ultrafine fibers are thinner and the specific surface area is larger, thereby forming smaller and more capillary holes, which not only greatly improves the hygroscopicity of the fabric, but also greatly improves its capillary wicking ability, so that it can absorb and store more liquid (oil or water). Therefore, ultrafine fibers can be applied to the development of highly absorbent products, such as highly absorbent pen cores, highly absorbent towels and other products. These gaps can absorb a large amount of water, so ultrafine fibers have strong water absorption, and most of the absorbed water is stored in the gaps and can be dried quickly, thereby effectively preventing the growth of bacteria. The absorbent ball 33 is made of highly absorbent resin, which is a newly developed functional polymer material containing strong hydrophilic groups and having a certain degree of crosslinking. The absorbent materials used in the past, such as paper, cotton, and linen, have a water absorption capacity of only 15 to 40 times their own weight (referring to deionized water, the same below), and their water retention capacity is also quite excellent.

[0027] Working principle: Existing skin-friendly knitted fabrics tend to fit human skin to avoid causing discomfort to human skin, but ignore water absorption, and have great limitations in use. In this embodiment, water penetrates into the third adsorption layer 36 through the first through hole 21, and passes through the flow channel 34, so that the water flows along the flow channel 34 and enters the placement groove 32. The water is absorbed by the strong water absorption of the water-absorbing ball 33. At the same time, the first adsorption layer 2, the second adsorption layer 4 and the third adsorption layer 36 are all water-absorbing, thereby improving the water absorption effect. Secondly, due to the setting of the water-locking inclined groove 23, water overflow is avoided, the water-locking ability is improved, and the water absorption of the cloth body is further improved.

[0028] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
