Description

Waterproof and breathable protective clothing fabric

Technical Field

The utility model relates to a protective clothing surface fabric, especially a waterproof ventilative protective clothing surface fabric.

Background

A medical protective garment is a garment for medical workers and is mainly used for isolating germs, harmful ultrafine dust, acidic solution, salt solution and the like. At present, medical protective clothing is mainly made of non-woven fabrics, but the non-woven fabrics have poor waterproof performance, so a layer of waterproof coating is generally coated on the surface of the non-woven fabrics to achieve the corresponding purposes of isolating germs, preventing water and the like. Although the existing protective clothing can achieve the protective effects of isolating germs, preventing water and the like, the air permeability of the existing protective clothing is poor, the wearing comfort is not good, and a wearer can sweat a large amount of sweat after wearing the protective clothing for a long time. Therefore, the prior art has the problem of poor air permeability.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a waterproof ventilative protective clothing surface fabric. The utility model has the characteristics of can effectively improve the gas permeability.

The technical scheme of the utility model: the waterproof and breathable protective clothing fabric comprises a polyester knitted fabric, wherein a PU film is arranged on the front surface of the polyester knitted fabric; the density of the terylene knitted fabric is 22 × 40M/CM, and the thickness of the PU film is 15 microns.

In the waterproof and breathable protective clothing fabric, the gram weight of the PU film is 10 g/square meter.

In the waterproof and breathable protective clothing fabric, the polyester knitted fabric is woven by guide bars GB1 and GB2, the weave structure of GB1 is 2-3/1-0//, and the weave structure of GB2 is 1-0/1-2//; yarns adopted by the guide bar GB1 and the guide bar GB2 are all terylene.

In the waterproof and breathable protective clothing fabric, the guide bar GB1 and the guide bar GB2 are full.

In the waterproof and breathable protective clothing fabric, a nano polytetrafluoroethylene microporous membrane is further arranged between the polyester knitted fabric and the PU membrane.

Compared with the prior art, the utility model discloses the dacron knitted fabric and the PU membrane that thickness is 15 microns that are 22 x 40M CM by density constitute, fine and close dacron knitted fabric backer adds waterproof ventilative PU membrane and complements each other, make the surface fabric have good air permeability, the surface fabric can drip the waterproof test that the infiltration is less than 4.5g through 500ml simultaneously, the test result of this fabric is far below 4.5g of standard, only 1-1.5g, the protective clothing made with this surface fabric can effectively keep apart the virus infiltration, protection medical personnel's life safety. Meanwhile, the utility model utilizes the elastic characteristics of the knitted fabric and the PU film, so that the fabric has higher wearing comfort and has smaller influence on the movement of each part of the body; as the protective clothing worn by medical personnel for a long time, the working efficiency can be greatly improved. To sum up, the utility model has the characteristics of can effectively improve the gas permeability.

Additionally, the utility model discloses still through set up nanometer polytetrafluoroethylene microporous membrane between dacron knitted fabric and PU membrane, further improve barrier propterty (like keeping apart bacterium etc.) and waterproof air permeability.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic representation of the organization of guide bar GB1 and guide bar GB 2.

The labels in the figures are: 1-polyester knitted fabric, 2-PU film and 3-nano polytetrafluoroethylene microporous film.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The waterproof and breathable protective clothing fabric is shown in figures 1 and 2 and comprises a polyester knitted fabric 1, wherein a PU film 2 is arranged on the front surface of the polyester knitted fabric 1; the density of the terylene knitted fabric 1 is 22 × 40M/CM, and the thickness of the PU film 2 is 15 microns.

The grammage of the PU film 2 is 10 g/m.

The polyester knitted fabric 1 is formed by weaving a guide bar GB1 and a guide bar GB2, the weave structure of GB1 is 2-3/1-0//, and the weave structure of GB2 is 1-0/1-2//; yarns adopted by the guide bar GB1 and the guide bar GB2 are all terylene. By adopting the weave structures of GB1 and GB2, the density of the woven fabric can reach 22 x 40M/CM, and the density of the woven fabric is effectively improved.

Both bar GB1 and bar GB2 are full penetration.

A nano polytetrafluoroethylene microporous membrane 3 is also arranged between the terylene knitted fabric 1 and the PU membrane 2.

The weaving of the polyester knitted fabric adopts a German KARLMAYER Terry type warp knitting machine, and the polyester knitted fabric is woven by utilizing a guide bar GB1 and a guide bar GB2 of the warp knitting machine.

22 x 40M/CM means that each CM length of the fabric has 22 coils in the transverse direction and 40 coils in the longitudinal direction.
