Description
Technical Field
The utility model relates to a waterproof ventilated membrane, in particular to a waterproof ventilated membrane of sportswear fabric.
Background
The sports clothes refer to clothes worn by people during sports, the sweat volume of the body is large at the moment, the clothes need to have good air permeability, namely, the clothes can quickly exchange heat generated by a human body with the external environment, and the internal temperature of the clothes is adjusted to be proper, so that the dryness and comfort of the skin are kept, but the air permeability of the existing clothes fabric is poor. In addition, most of sportswear worn by people is used for outdoor sports, and the existing sportswear is poor in waterproof performance and easy to wet when meeting water, so that normal use is influenced. Therefore, the prior art has the problem of poor waterproof performance and air permeability.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a waterproof ventilated membrane of sports garment materials.
The utility model has the characteristics of can effectively improve waterproof and gas permeability.
The technical scheme of the utility model: a waterproof breathable film of a sportswear fabric comprises a breathable base fabric, wherein a base film is arranged on the outer side of the breathable base fabric; the base membrane comprises an upper polytetrafluoroethylene microporous membrane layer, a middle polytetrafluoroethylene microporous membrane layer and a lower polytetrafluoroethylene microporous membrane layer; an upper conical hole is formed in the upper polytetrafluoroethylene microporous membrane layer, a round hole corresponding to the upper conical hole in position is formed in the middle polytetrafluoroethylene microporous membrane layer, and a lower conical hole is formed in the lower polytetrafluoroethylene microporous membrane layer.
In the waterproof and breathable film of the sportswear fabric, the breathable base fabric is formed by warp and weft knitting; the warp yarns are formed by blending flat cross-shaped polyester fibers and bamboo charcoal fibers, and the weft yarns are formed by blending W-shaped polyester fibers and mica cool fibers.
In the waterproof and breathable film of the sportswear fabric, the breathable base fabric is provided with the honeycomb-shaped breathable holes.
In the waterproof and breathable film of the sportswear fabric, an antibacterial coating is further arranged between the breathable base fabric and the base film.
In the waterproof breathable film of the sportswear fabric, the diameter of the section of the upper end of the upper conical hole is smaller than that of the section of the lower end of the upper conical hole.
In the waterproof breathable film of the sportswear fabric, the diameter of the section of the upper end of the lower tapered hole is larger than the diameter of the section of the lower end of the lower tapered hole.
Compared with the prior art, the utility model discloses constitute by ventilative base cloth and base film, and the base film comprises upper portion polytetrafluoroethylene microporous membrane, middle part polytetrafluoroethylene microporous membrane and lower part polytetrafluoroethylene microporous membrane again for the membrane wholly has good waterproof air permeability. Particularly, the utility model has good waterproof performance while ensuring the air permeability by arranging the upper conical hole, the round hole and the lower conical hole in sequence; the breathable base fabric is formed by weaving warps consisting of flat cross-shaped polyester fibers and bamboo charcoal fibers and wefts consisting of W-shaped polyester fibers and mica cool fibers, and has good breathability and cool and comfortable performance. To sum up, the utility model has the characteristics of can effectively improve waterproof and gas permeability.
