[0040] Example 1:

[0041] In view of the low comfort, poor air permeability, relatively hot, noisy sound, sleep interference, appearance and texture affected problems of the waterproof pad in the prior art, such as Figure 1 As shown in the figure, it is a preferred embodiment of the knitted waterproof pad of the utility model, the knitted waterproof pad comprises surface material 1, filling layer 2, PTFE film 3 and inside material 4 connected in sequence from top to bottom, and the surface material 1 and the inside material 4 are both knitted fabrics.

[0042] The above-mentioned knitted waterproof pad adopts a four-layer composite structure of surface fabric 1 + filling layer 2 + PTFE film 3 + inner fabric 4, and the surface fabric 1 and the inner fabric 4 are both knitted fabrics, and has the following advantages:

[0043] I. Soft and comfortable touch: Compared with the conventional waterproof pad, which may not be as soft as the ordinary mattress, the hand feeling is hard, the comfort is not high, and the sleep experience is affected, the waterproof pad of the utility model adopts a multi-layer structure, and the composite use of the PTFE film 3 uses a knitted fabric with higher softness as the surface fabric 1 and the inner fabric 4, which maintains good softness, and at the same time, the surface fabric 1 adopts a knitted fabric with soft texture, comfortable touch, and certain elasticity, which can better fit the skin or close-fitting clothes than the woven fabric, so that the use of the waterproof pad is more comfortable, and the waterproof pad can be directly used as a bed surface of a mattress or a bed cover.

[0044] II. Good air permeability and moisture permeability: Compared with the conventional waterproof pad product, which has moisture permeability but low air permeability, for example, the test report No: 230262146 shows that the air permeability is less than 1 mm / s, which may cause a feeling of stuffiness during sleep, the surface fabric 1 and the inner fabric 4 of the utility model adopt a knitted fabric, which has more air permeation channels and better air permeability than a woven fabric; the PTFE film 3 is a microporous film material made of polytetrafluoroethylene resin through a process, which can effectively block liquid water, and the microporous structure allows gas to pass through, which not only has excellent moisture permeability, but also can maintain air permeability, thereby comprehensively making the waterproof pad have good moisture permeability and high air permeability, and is not easy to be stuffy.

[0045] III. Excellent waterproofness: PTFE film 3 is highly hydrophobic and can effectively block liquid water, which is suitable for waterproof and breathable applications. The utility model adopts a multi-layer structure, which can achieve a high level of static water pressure while ensuring softness. The detection resistance reaches a static water pressure value P (kPa) > 50, meets the performance requirements of waterproof grade 5, and has excellent waterproof performance.

[0046] IV. Quiet use: Compared with the existing waterproof pad, which may produce noise when moving due to certain materials, disturbing sleep, the waterproof pad of the utility model adopts a soft knitted fabric and a PTFE film 3, with a filling layer 2 in between, which is more soft and quiet, and is not easy to have the rubbing sound of the conventional composite film, so as to improve the sleep experience.

[0047] V. Easy to clean: The above-mentioned waterproof pad can be directly machine washed to keep clean, and the waterproof function will not be affected after multiple washes.

[0048] Six, better appearance and texture: compared to some waterproof pad products, the waterproof film is more or less composite with non-woven fabric or woven fabric, some products are directly composite with the upper fabric or filling, the appearance and texture are not as good as ordinary pad, which may affect the appearance and use, the utility model adopts a multi-layer composite structure, PTFE film 3 inside, and the surface fabric 1 and the inside fabric 4 are knitted fabrics, the appearance and texture are better.

[0049] Further, the surface fabric 1 adopts a knitted functional fabric, including knitted single-side nylon fabric, knitted single-side spandex fabric or knitted single-side double-component fabric, which aims to further improve the comfort and functionality of the waterproof pad, achieve more comfortable and breathable use, use finer raw materials to improve the fabric hand feeling and comfortable fabric touch.

[0050] The knitted single-side nylon fabric is a cool fabric made of nylon fiber as the main raw material and single-side knitting process, which has the advantages of strong wear resistance, good elasticity, not easy to deform, good moisture absorption, can absorb skin surface sweat, keep skin dry, light texture, good corrosion resistance, not easy to be wormed, easy to store and the like.

[0051] The knitted single-side spandex fabric is a cool fabric made of spandex as the main raw material and single-side knitting process, which has the advantages of high elasticity, good wear resistance, good moisture absorption and air permeability, chemical resistance, dry cleaning resistance and the like.

[0052] The knitted single-side double-component fabric is a fabric made of yarns of two different fiber components and single-side knitting process, which can combine the advantages of different fiber characteristics, have various appearances, good air permeability and moisture absorption, elasticity and stability, and further improve the functionality of the waterproof pad.

[0054] Further, the inside fabric 4 is a knitted double-sided fabric woven from polyester, and the denier of polyester is 30D-80D. The knitted double-sided fabric is mainly made of polyester and is woven by double-layer knitting process. Compared with single-layer knitting, it has the advantages of high stiffness, high comfort, and various designs. Moreover, its soft hand feeling makes the inside fabric 4 adopt soft and thin knitted fabric, which, after being combined with the PTFE membrane 3, effectively improves the softness while being quiet and more comfortable.

[0055] Further, the surface of the knitted double-sided fabric is provided with a sanding layer. The sanding layer is a layer of short and dense nap formed on the surface of the knitted double-sided fabric by sanding process, which improves the moisture absorption. Moreover, the knitted fabric has the characteristic of particularly soft hand feeling, and the grammage is between 90-130gsm to ensure its soft hand feeling.

[0056] Further, the filling layer 2 includes a first non-woven fabric 201, a filler 202 and a second non-woven fabric 203 arranged from top to bottom. For example, the first non-woven fabric 201 and the second non-woven fabric 203 are polypropylene non-woven fabrics. The use of non-woven fabric and filler 202 can achieve the effects of beauty, comfort and practicality, and further improve the softness and quietness of the waterproof pad. The non-woven fabric covers the filler 202 to fix and prevent the displacement of the filler 202, and improves the washing resistance of the waterproof pad.

[0057] Further, the thickness of the PTFE film 3 is 0.01-0.05 mm, which is thinner and softer, and the softness is better and the waterproof performance is not affected.

[0058] Further, the PTFE film 3 is connected with the filling layer 2 or the inside material 4 by the glue compounding process of the environment-friendly hot melt adhesive, and uniform and good bonding can be formed.

[0059] Further, the quilted stitching is fixed outside the surface material 1 and the filling layer 2, and the multi-layer composite structure and the filling quilted stitching are adopted, so that the water washing resistance and the machine washing resistance are better.

[0060] The manufacturing method of the knitted waterproof pad can include: adopting twice compounding, i.e., first, the surface material 1 and the filling layer 2 are quilted by a plurality of needles to obtain an upper piece 5, the inside material 4 and the PTFE film 3 are compounded to obtain a lower piece 6, and then the filling layer 2 of the upper piece 5 and the PTFE film 3 of the lower piece 6 are compounded to obtain the knitted waterproof pad; the quilted pattern of the quilted stitching can be selected as required, and is not limited.

[0061] The knitted waterproof pad can be used as a mattress, and can also be used as a urine isolation pad, a cushion, an outdoor product, etc., and the shape and size of the knitted waterproof pad can be set according to the use requirement.
