Abstract

The utility model discloses a waterproof and moisture-permeable complex clothing material used for manufacturing clothes and gloves, which is composed of superfine fiber non-woven fabrics (1) at one side surface of the material and a moister-conductive layer (2) covered on the fabrics. When the moisture gap molecules out of sweating are absorbed by the inner surface of the moister-conductive layer of the clothing material, the moister-conductive layer discharges the sweat molecules outside of the clothes through its moister-conductive function. Meanwhile rain or melted snow at the exterior of the clothing material is not conducted to the interior of the moister-conductive layer, therefore the material has the water-proof and moisture-permeable function. Through testing, the moisture permeability is above 8000g/m<2>24h, and in extremely cold areas about the -40 DEG C, the complex clothing material contains to be soft and also has no crackles after the material is bended repetitively 50,000 times, which proves that the life span of the material is obviously expanded.

Description

Waterproof Breathable composite bed garment material

(1) technical field: the utility model relates to the synthetic fabric production technology; Be specifically related to a kind of people and manufacture the Waterproof Breathable composite bed garment material that clothes, gloves are used.

(2) background technology: people manufacture the synthetic leather lining that clothes, gloves are used in the prior art, are to apply in nonwoven surface to be connected with PVC or polyamine fat material constitutes.Though play certain anti-chill, the effect of rain and snow, but still have the following disadvantages: the one, be coated in the not saturating moisture of synthetic leather lining on the nonwoven surface, people dress the clothes that adopt its lining to manufacture in life and work, when gloves are perspired, the wet gas that produces can't be discharged to extraneous atmospheric environment by the synthetic leather precoat, put the sweat wet gas of staying synthetic leather lining inner layer surface and feel cold and become cold, what make that people are worn on body feels very uncomfortable; The 2nd, manufacture the synthetic leather lining of clothes, gloves and dress the jackknifing breakage of easily hardening at cold district, shortened its service life.

(3) summary of the invention: at the deficiency of above-mentioned existence, the purpose of this utility model is to provide a kind of Waterproof Breathable composite bed garment material, be intended in people's life and work, the lining that is worn on body both can prevent the intrusion of extraneous rain, snow-broth, the wet gas of distributing of human body can being perspired is again in time conducted outside the discharge clothes, and soft the resisting cold of fabric texture is difficult for jackknifing, improves its service life.

For achieving the above object, the technical solution of the utility model is achieved in that this Waterproof Breathable composite bed garment material, and its improvement is: on a side surface of superfine fibre nonwoven cloth, be laminated with and be connected with wetness-guiding layer.

The wetness-guiding layer that the utility model is selected for use usually is to adopt the TPU material film layer with wet guiding function; Or on PTFE material film laminar surface, be covered with several micropores that loose moisture thoroughly and constitute.

The utility model is connected with on the outer surface of wetness-guiding layer at above-mentioned superfine fibre nonwoven cloth usually, is connected with the lining cloth layer.

The utility model adopts above-mentioned a kind of lamination layer structure, by at the bonding strength height, on the nonwoven surface that the superfine fibre that softness and gas permeability are strong constitutes, be laminated with and be connected with TPU material film wetness-guiding layer, wet gas hydrone when human body perspiration generation, when being adsorbed on the TPU material film wetness-guiding layer inner surface of garment material, because the wetness-guiding layer material contains very easily the hydrophilic radical with water molecules, can be with the wet gas hydrone from high-temperature aspect (near the wetness-guiding layer inner surface of human body skin), conduct discharge to low temperature aspect (the wetness-guiding layer outer surface that directly contact with the ambient atmosphere environment temperature).Because the wetness-guiding layer ambient temperature is lower than the temperature of its inboard near human body skin, makes the rain, the snow-broth pearl that place on the wetness-guiding layer outer surface, then can't realize the purpose of Waterproof Breathable by the conduction of lateral wetness-guiding layer inner surface.

The utility model adopts above-mentioned another kind of lamination layer structure, is on the surface of superfine fibre nonwoven cloth, is laminated with and is connected with PTFE material film wetness-guiding layer, and be covered with the micropore of some moistures that loose in its surface.The diameter of described micropore is bigger than the wet gas hydrone diameter that people sweat produces, but it is littler than extraneous rain, snow-broth pearl diameter, so having realized the wet gas of human body both can discharge by the garment material conduction smoothly, prevented that again the globule that extraneous rain, snow form from entering its inner surface by the wetness-guiding layer micropore, realized the purpose of Waterproof Breathable equally.

The clothes that the utility model composite bed garment material is manufactured, gloves are by testing: moisture permeability is at 8000g/m ²More than the 24h, the wet gas hydrone that produces that guaranteed to perspire in people's work or the motion in time conducts discharge; The extremely frigid zones composite bed garment material of-40 ℃ of temperature still softness as before, bend repeatedly 50,000 times flawless, improved its service life significantly.

Fig. 1 has the amplification schematic perspective view of part section for first kind of embodiment of the utility model;

Fig. 2 has the amplification schematic perspective view of part section for second kind of embodiment of the utility model;

Fig. 3 has the amplification schematic perspective view of part section for the third embodiment of the utility model.

(5) specific embodiment: embodiment one.Usually select for use the strong superfine fibre nonwoven cloth of good permeability, bonding strength height and soft bending resistance folding endurance as base cloth layer, on a side surface of described superfine fibre nonwoven cloth 1, evenly being laminated with the wetness-guiding layer 2 that is connected with by special equipment, is to be made of TPU material film layer; The thickness (shown in Figure 1) about 0.02mm of common TPU material film wetness-guiding layer 2.When making clothes, gloves,, be connected with on the outer surface of TPU material film wetness-guiding layer 2 at described superfine fibre nonwoven cloth usually, be laminated with again and be connected with lining cloth layer 4 (shown in Figure 3) for strengthening the soft comfort of its lining internal layer.

Embodiment two.Present embodiment with embodiment one different be that described wetness-guiding layer 2 is on the thin layer surface that is made of the PTFE material, is covered with the micropore 3 (shown in Figure 2) of several moistures that loose thoroughly.Described micropore 3 diameter dimensions are typically chosen in and can make the sweat hydrone outwards conduct discharge smoothly, guarantee that again rain, the snow-broth pearl in the outside air environment can not enter in its micropore 3, and the diameter of micropore 3 is in 0.1 μ-0.4 μ scope usually.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characterictic that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
