Description
Technical field
The utility model is related to one kind both without PUR, just can be non-woven fabric compounded by surface layer without stretched non-woven cloth
The high-elasticity ventilating folding crape formula compound nonwoven cloth on elastic film surface, is mainly used in medical bandage and health is used in a stretched state
Product, category compound nonwoven cloth manufacture field.
Background technology
CN202213263U, title " a kind of compound nonwoven cloth ", by least one layer of elastic non-woven cloth and at least one layer elasticity
Film is composited.The elastic membrane is polyurethane film.The elastic non-woven cloth and elastic membrane are composited by adhesive.Institute
Adhesive is stated for PUR.Elastic non-woven cloth and elastic polyurethane ventilated membrane are in extended state when carrying out composition operation,
The automatic retracted after the completion of compound.Its weak point：One needs elastic non-woven cloth and bullet when being the compound nonwoven cloth composite molding
Property polyurethane ventilated membrane complete compound in extended state, the elasticity of the elastic membrane of the non-woven fabrics after composite molding by elasticity by
The restriction of elastic non-woven cloth, what is obtained is the compound nonwoven cloth being limited with elastic non-woven cloth elasticity, and its elasticity is very limited；Two are
The complex dependence of elastic non-woven cloth and elastic polyurethane ventilated membrane is in PUR, and the basic resin of PUR is ethene and acetic acid
The EVA resin of ethene copolymerization at high temperature under high pressure, and the viscosity of EVA resin itself is very low, need to add tackifier, it is such as modified
Rosin（138 or 145）, C5 Petropols, C9 Petropols, terpene resin etc., the addition of these compositions causes the viscous of PUR
Property enhancing, but its as elastic non-woven cloth and elastic polyurethane ventilated membrane complex media when, elastomeric nonwoven is but plugged significantly
The gas permeability of cloth, substantially reduces the gas permeability of the compound nonwoven cloth after composite molding, or even very poor.
Utility model content
Purpose of design：The weak point in background technology is avoided, design one kind is both without PUR, without stretched non-woven
Cloth, just can answer the high-elasticity ventilating folding crape formula on the non-woven fabric compounded two sides of elastic membrane in a stretched state of surface layer non-woven fabrics and bottom
Close non-woven fabrics.
Design：In order to realize above-mentioned purpose of design.The utility model is in structure design：1st, the film surface of elastic membrane has
The design of many air-vents, is one of technical characteristic of the present utility model.The purpose so designed is：Due to the utility model
The film surface of the elastic membrane is under tension with nonwoven cloth cover without glue（Without PUR）Compound, i.e., air-permeable elastic film is being drawn
Stretch the film surface of air-permeable elastic film under state to be combined with the direct hot pressing of non-woven fabrics, will not occur PUR and block elastic film surface air-vent
Phenomenon.Secondly, air-permeable elastic film is advantageous in that：One is that it can not only make this air-locked elastic membrane become ventilated membrane,
And can increase the extensibility for being covered with the elastic membrane of air-vent --- elasticity is good, is effectively improved the flexible of air-permeable elastic film
Rate；Two be to use air-permeable elastic film of the present utility model, it can it replace current paper diaper elastic waistline auxiliary material to use elastic
Make brought manufacturing equipment complexity, complex manufacturing technology, cost high, efficiency is low, and using adhesive positioning elastic institute
Caused waistline auxiliary material elastic force decline, poor air permeability, the defect that feel is stiff, comfortableness is poor；Two be using of the present utility model
Bandage auxiliary material made by air-permeable elastic film, not only elastic good, good permeability, and also flatness during taut bundle is good, cost of manufacture
It is low.2nd, the design that the elastic membrane with many air-vents is combined with the hot pressing of surface layer non-woven fabrics in a stretched state, is that this practicality is new
The two of the technical characteristic of type.The purpose so designed is：Because the non-woven fabrics for medical bandage and amenities had both been required
With fine air permeability and flatness, require that there is good elasticity again, while price is low, and disclosure satisfy that the face of above-mentioned requirements
The elasticity of layer non-woven fabrics is very small, is substantially negligible and disregards, but needed for medical bandage auxiliary material and paper diaper waistline auxiliary material
Elastic composite nonwoven fabric be then both required to meet flatness, the flexible requirement of strong elastic is required to meet again, is that this this practicality is new
Air-permeable elastic film is formed air-permeable elastic folding crape formula with the compound rear resilience of surface layer non-woven fabrics hot pressing under tension and is combined by type
Non-woven fabrics, had both met that medical bandage auxiliary material is ventilative, smooth, elastic colligation requirement, and paper diaper waistline auxiliary material institute is met again
The requirement for needing smooth, ventilative, strong elastic flexible.3rd, the negative pressure suction inlet that air-vent shapes in elastic membrane is along in boss mouth structure
Design, is the three of technical characteristic of the present utility model.The purpose so designed is：Elastic film surface is being punched by negative pressure ventilation
During, the negative-pressure ward hole in its elastic film surface（Negative pressure air-out one end）Hole along in boss mouthful, the boss platform is just just as cloth
In the multiple hole shape supports of elastic film surface, the orifice part that should be supported due to hole shape is higher than film surface, therefore when other non-woven fabrics are combined,
So that nonwoven cloth cover forms the hollow multi-point support that multichannel and road road are communicated with the boss mouthful of elastic film surface.
Technical scheme：A kind of high-elasticity ventilating rolls over crape formula compound nonwoven cloth, including non-woven fabrics, and the film surface of elastic membrane has a lot
Air-vent, the elastic membrane with many air-vents constitutes high resiliency with the compound rear resilience of surface layer non-woven fabrics hot pressing in a stretched state
Between ventilative folding crape formula compound nonwoven cloth.
The utility model is compared with background technology, and one is without PUR, you can realize surface layer non-woven fabrics and elastic membrane
It is compound, it is ensured that the gas permeability of elastic membrane and non-woven fabrics in itself is not influenceed by PUR；Two be the design of open-celled flexible film, no
The characteristics of only making elastic membrane extensibility greatly increase, and there is high-tension, big extensibility；Three be aperture boss in elastic membrane
Design, realize the compound of non-woven fabrics and elastic membrane boss orifice part, not only considerably reduce non-woven fabrics and elastic membrane
Compound area, and telescopic resilience is good, starts the precedent for making the penetrating compound nonwoven cloth of hollow multi-point support.
