Abstract
A composite non-woven cloth with air permeable films (that is non-woven cloth + air permeable film or non-woven cloth + air permeable film + non-woven cloth), relates to the non-woven cloth field, which is compounded from non-woven cloth materials and air permeable film materials through hot melt adhesive. The compounded non-woven cloth is a new waterproof air permeable material, which has the performances of being antibacterial, antistatic, flame retardant, odor resistant, anti-bloodiness, anti- electromagnetic wave, anti-chemical corrosion and with no falling elements or dust. The utility model is characterized in soft hand, comfortable, good waterproof performance and air permeability and big extending ratio, so the utility model can be suitable in the fields of military, medical treatment, clean workshop, protective articles, packing supplies and woman and baby hygienic articles.
Description
Technical field
Technical field under the utility model is a composite non-weaving cloth.
Background technology
Though the composite non-weaving cloth that generally uses has water-proof function at present, can not breathe freely; Though common non-weaving cloth is ventilative non-watertight, and certain limitation is all arranged in the use, be difficult to adapt to growing all trades and professions, particularly relate to the widespread demand of high-tech sector and industry.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of waterproof, resistance to chemical attack, and has the compound nonwoven cloth of highly-breathable energy.
For solving the problems of the technologies described above, the utility model provides a kind of compound nonwoven cloth that contains breathable films, is composited through hot melt adhesive by one deck non-weaving cloth and one deck breathable films material or multi-layer nonwoven cloth and one deck breathable films material.
Described breathable films is the polytetrafluoroethylmicroporous microporous membrane that contains organic/inorganic substance, and at film surface wide dispersion 0.3-10 μ m micropore, the density of micropore can reach 9,000,000,000/cm
2, its gas permeability reaches 3000-10000g/m
224h.
Described non-weaving cloth is a kind of fiber with orientation or random alignment, and by friction, obvolvent or bonding method, perhaps the tablet of making by the combined method of these methods, fibre web formula batts are also referred to as nonwoven fabric.But because of the performance difference of the different nonwoven fabric of material and production technology very big.In the utility model, mainly adopt the immersion non-woven fabrics of present state-of-the-art technology and explained hereafter or spunlace non-woven cloth etc.That this class nonwoven fabric has is soft, good permeability, nothing fall, and wadding takes off characteristics such as dirt.
A kind of compound nonwoven cloth that contains breathable films provided by the utility model, possess waterproof, ventilative, do not have the wadding of falling and take off characteristics such as dirt, antistatic, resistance to chemical attack; Texture, intensity height with natural fabric can be made into products such as medical material, medical operation clothes and operation articles for use, clean working garment, chemical protecting suit, BIG.
Description of drawings
Accompanying drawing is the schematic diagram according to the one kind of form of this practical proposition.
The specific embodiment
Shown in the accompanying drawing, present embodiment is to be composited by the polytetrafluoroethylene (PTFE) breathable films 2 that two-layer spunlace non-woven cloth or immersion non-woven fabrics 1 and one deck are clipped in the middle.
Spunlace non-woven cloth or immersion non-woven fabrics 1 are known technologies.
The manufacture process of polytetrafluoroethylene (PTFE) breathable films 2 is as follows:
The polytetrafluoroethylene (PTFE) breathable films adopts The tape casting production to contain the polytetrafluoroethylene film of inorganic matter, and through multi tension, forms 0.3-10 μ m micropore on the film surface, and the density of micropore can reach 9,000,000,000/cm
2, form film with waterproof, permeability.Its gas permeability reaches 3000-10000g/m
224h is far above other breathable films.
Surface layer and primer spray hot melt adhesive on base material before unreeling, draw, being transported to composite roll, form through pressing, bonding again.The finished product of this product through being processed into all shows through test of many times: good waterproof, ventilative, comfortableness are arranged, and extremely similar to common natural fibre products, possess the favorable protection isolation effect simultaneously.Can effectively prevent the infringement of bacterium, virus, sewage and chemicals, isolate dust, hair, skin exfoliation cell etc. and enter clean environment human body.
Claims (3)
1, a kind of compound nonwoven cloth that contains breathable films is composited by one or more layers non-weaving cloth and one deck breathable films, it is characterized in that: on the described breathable films, wide dispersion have diameter be 10 μ m following micropore.
2, compound nonwoven cloth according to claim 1 is characterized in that: described breathable films is the polytetrafluoroethylmicroporous microporous membrane that contains organic/inorganic substance.
3, compound nonwoven cloth according to claim 1 and 2 is composited through hot melt adhesive.
