Technical Field
The utility model relates to a textile material technical field especially relates to a waterproof ventilative layer surface fabric of high moisture permeability.
Background
The waterproof breathable layer fabric is an important combined component in the safety protection of the fire-fighting protective clothing for firemen, has the characteristics of important safety protection functions such as flame retardance, high temperature resistance, water resistance and the like, and is thick and heavy in design in order to meet the requirement of high heat insulation performance, so that the wearing comfort is poor, and the operation efficiency is also influenced. Therefore, the improvement of the wearing comfort of the whole garment becomes the design direction of the garment function.
The waterproof and moisture permeable performance of the waterproof and breathable layer is the most important factor of the overall wearing comfort performance sense of the protective clothing, external water can be prevented from entering the interior of the clothing through water resistance, and the moisture permeable performance can conduct away hot moisture generated by movement of a wearer without influencing the comfort. For GA10 firefighter fire-extinguishing protective clothing, the standard requirement is that the moisture permeability of the waterproof and breathable layer is not less than 5000 g/square meter.24 h. Therefore, the design for improving the moisture permeability of the waterproof breathable layer is an important direction for the design combination of the protective clothing.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an above-mentioned problem of solving among the prior art provides a waterproof ventilative layer surface fabric of high moisture permeability, uses the non-woven fabrics surface fabric that contains the hole as the base cloth material, has reduced the impedance power of penetrating wet PTFE membrane, has improved the moisture permeability of waterproof ventilative layer surface fabric, and the increase of hole air also promotes the heat-proof quality of combination to a certain extent.
In order to achieve the purpose, the utility model adopts the technical proposal that:
the utility model provides a waterproof ventilative layer surface fabric of high pass through moisture, including arranging in proper order: the base cloth layer is a flame-retardant high-temperature-resistant layer and is provided with a plurality of holes, the bonding layer is a flame-retardant high-temperature-resistant glue layer, and the film layer is a PTFE film layer.
Preferably, the base fabric layer is a flame-retardant high-temperature-resistant carbonized nonwoven fabric.
Preferably, the flame-retardant high-temperature-resistant carbonized nonwoven fabric is spun by one or more of carbon fiber, aramid fiber, polyester fiber, polysulfonamide, polyimide and PBI.
