Multi-functional pair of component compound fabric of air-moisture-permeable waterproof
Technical field
The utility model relates to a kind of multi-functional pair of component compound fabric of air-moisture-permeable waterproof, belongs to the weaving face fabric technical field.
Background technology
Waterproof Breathable coating fabric of the prior art mainly is a hydrophilic Waterproof Breathable coating fabric.The moisture permeation mechanism of hydrophilic Waterproof Breathable coating fabric is to be contacted with fabric face by sweat vapour, is delivered to the external world through hydrophilic radical.The greatest problem that this lining exists is exactly: the hydrophilic radical adsorbed water molecule, and make fabric become very thick and heavy, clammy, the human body dress has discomfort.On the one hand, existing processes pass through the wetted surface material, meet water and be prone to produce Peng Run, cause the epithelium wearability to descend, and the fabric moisture transmission performance relatively a little less than, general moisture permeability index is 2500-3500G/M.24H (JIS 1099A1).On the other hand; Existing pore type waterproof moisture permeable fabric utilizes micropore row aproll steam; Make moisture arrange diffusing to extraneous air from temperature and the higher relatively side of humidity with being ordered about passing property; Rather than lean on hydrophilic radical transmission, this row mode of loosing more to discharge mode near the normal sweat of human body, seeming is fit to the comfort requirement of human body more.But because the specific area of pore type waterproof moisture permeable fabric is big; Materials such as dust, the salt in the sweat, grease cosmetics and washing agent in the easy absorbed air, these materials are inhaled in the membrane micropore, cause the obstruction of micropore on the one hand; These dirts can produce capillary effect in micropore on the other hand; Make the infiltration of the globule or ooze out easily, cause As time goes on, pore type waterproof moisture permeable fabric dress ornament water vapour permeability descends.
Therefore, how to design a kind of compound fabric of air-moisture-permeable waterproof, can keep the performance of waterproof and perspire vapour for a long time, become the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model purpose provides a kind of multi-functional pair of component compound fabric of air-moisture-permeable waterproof; This compound fabric can be prevented rainwater; Helping human body sweat vapour again discharges; And can keep the performance of waterproof and perspire vapour for a long time, make lining have better comfort property and wide applications more.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of multi-functional pair of component compound fabric of air-moisture-permeable waterproof; Comprise base cloth layer, said base cloth layer one side is coated with has the hydrophilic layer of polyurethane of refusing oil, and this layer of polyurethane opposite side is bonded with the polytetrafluoroethylene film layer through first glue layer; This polytetrafluoroethylene film layer number of hole per square inch is 85~9,500,000,000, and the average diameter of hole is 0.2um~10um; The outer bed of cloth of vapor-permeable type is bonded in said polytetrafluoroethylene film layer opposite side through second glue layer; The said polytetrafluoroethylene film layer and the layer of polyurethane gross mass of dried state are 80~90% of said base cloth layer quality.
Further improved technical scheme is following in the technique scheme:
As preferably, said base cloth layer is a kind of in cotton, polyester-mixed cotton cloth, terylene and the polyamide fabric.
As preferably, the volume of hole accounts for 80~90% of polytetrafluoroethylene film layer volume in the polytetrafluoroethylene film layer.
As preferably, the mass ratio between said polytetrafluoroethylene film layer and the layer of polyurethane is 1: 6.5~7.
As preferably, the thickness ratio is 28: 6: 2 between said base cloth layer, layer of polyurethane, polytetrafluoroethylene film layer and the outer bed of cloth: 36.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
Multi-functional pair of component compound fabric of the utility model air-moisture-permeable waterproof; Outside having the polytetrafluoroethylene film layer outer surface in micropore hole, be covered with the outer bed of cloth of vapor-permeable type; Thereby can avoid still because the materials such as dust, the salt in the sweat, grease cosmetics and washing agent in the pore type polytetrafluoroethylene film layer absorbed air have been realized the waterproof and the perspire vapour performance that keep stable for a long time; Secondly; In conjunction with having the hydrophilic urethane resin layer of refusing oil and having the polytetrafluoroethylene film layer of hole; When improving external prevention rainwater performance, the performance that has strengthened internal discharge human body sweat vapour is arranged, make fabric have better comfort property and wide applications more; Once more; Because the moisture-permeability waterproof coating has the hole that all has in a large number; And have hydrophilic refuse oil urethane resin layer; Thereby more help discharge, greatly reduce the moisture of residual thin polyurethane film surface, thereby improved the wearability of coating fabric and worn dry and comfortable from the human body water vapour.
Description of drawings
Accompanying drawing 1 is a multi-functional pair of component compound fabric structural representation of the utility model air-moisture-permeable waterproof.
In the above accompanying drawing: 1, base cloth layer; 2, layer of polyurethane; 3, first glue layer; 4, polytetrafluoroethylene film layer; 5, hole; 6, outer bed of cloth; 7, second glue layer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: a kind of multi-functional pair of component compound fabric of air-moisture-permeable waterproof, comprise base cloth layer 1, this base cloth layer 1 is a kind of in cotton, polyester-mixed cotton cloth, terylene and the polyamide fabric.
Said base cloth layer 1 one sides are coated with has the hydrophilic layer of polyurethane 2 of refusing oil; These layer of polyurethane 2 opposite sides are bonded with polytetrafluoroethylene film layer 4 through first glue layer 3; This polytetrafluoroethylene film layer 4 number of hole 5 per square inch is 85~9,500,000,000, and the average diameter of hole 5 is that the outer bed of cloth 6 of 0.2um~10um vapor-permeable type is bonded in said polytetrafluoroethylene film layer 4 opposite side through second glue layer 7; The said polytetrafluoroethylene film layer 4 and layer of polyurethane 2 gross masses of dried state are 80~90% of said base cloth layer 1 quality.
Does the volume of hole 5 account for polytetrafluoroethylene film layer 4 volume in the above-mentioned polytetrafluoroethylene film layer 4?~? %;
Mass ratio between above-mentioned polytetrafluoroethylene film layer 4 and the layer of polyurethane 2 is 1: 6.5~7.
The thickness ratio is 28: 6: 2 between above-mentioned base cloth layer 1, layer of polyurethane 2, polytetrafluoroethylene film layer 4 and the outer bed of cloth 6: 36.
When adopting multi-functional pair of component compound fabric of above-mentioned air-moisture-permeable waterproof; Outside having the polytetrafluoroethylene film layer outer surface in micropore hole, be covered with the outer bed of cloth of vapor-permeable type; Thereby can avoid still because the materials such as dust, the salt in the sweat, grease cosmetics and washing agent in the pore type polytetrafluoroethylene film layer absorbed air have been realized the waterproof and the perspire vapour performance that keep stable for a long time; Secondly; In conjunction with having the hydrophilic urethane resin layer of refusing oil and having the polytetrafluoroethylene film layer of hole; When improving external prevention rainwater performance, the performance that has strengthened internal discharge human body sweat vapour is arranged, make fabric have better comfort property and wide applications more; Once more; Because the moisture-permeability waterproof coating has the hole that all has in a large number; And have hydrophilic refuse oil urethane resin layer; Thereby more help discharge, greatly reduce the moisture of residual thin polyurethane film surface, thereby improved the wearability of coating fabric and worn dry and comfortable from the human body water vapour.
