Description
Technical field
One kind be the utility model is related to both without PUR, just can be non-woven fabric compounded by bottom without stretched non-woven cloth
The ventilative folding crape formula compound nonwoven cloth of the elastic hollow of elastic film surface boss oral area in a stretched state, be mainly used in medical bandage and
Amenities, belong to compound nonwoven cloth manufacturing 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 combined.The elastic membrane is polyurethane film.The elastic non-woven cloth and elastic membrane are combined by adhesive.Institute
It is PUR to state adhesive.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：First, need elastic non-woven cloth and bullet during the compound nonwoven cloth composite molding
Property polyurethane ventilated membrane in extended state complete it is compound, the elastic membrane of the non-woven fabrics after composite molding elasticity 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；Second,
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 that ethene is copolymerized 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 during its complex media as elastic non-woven cloth and elastic polyurethane ventilated membrane, but plug elastomeric nonwoven significantly
The gas permeability of cloth, substantially reduce the gas permeability of the compound nonwoven cloth after composite molding, in addition it is 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 be by the ventilative folding crape formula of the elastic hollow on the non-woven fabric compounded two sides of elastic membrane in a stretched state of surface layer non-woven fabrics and bottom
Compound nonwoven cloth.
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 the technical characteristics of the utility model.The purpose so designed is：Due to the utility model
The elastic hole drilling ventilation film is under tension with nonwoven cloth cover without glue（Without PUR）It is compound, i.e., elastic hole drilling ventilation
The film surface of film is compound with the direct hot pressing of non-woven fabrics in a stretched state, and PUR will not occur and block elastic hole drilling ventilation film surface
The phenomenon of air-vent.Secondly, elastic hole drilling ventilation film is advantageous in that：First, it can not only become this air-locked elastic membrane
Into punching ventilated membrane, and the extensibility increase for being covered with the elastic membrane of air-vent can be made --- it is elastic good, it is effectively improved elasticity
The expansion and contraction of hole drilling ventilation film；Second, using elastic hole drilling ventilation film of the present utility model, it being capable of its current paper diaper of substitution
Elastic waistline is high using manufacturing equipment complexity, complex manufacturing technology, cost caused by elastic making, and efficiency is low, and uses
The decline of waistline elastic force, poor air permeability caused by adhesive positioning elastic, the defects of feel is stiff, comfortableness is poor；Second, use
Bandage made by elastic hole drilling ventilation film of the present utility model, not only elastic good, good permeability, and flatness during taut bundle
It is good, low manufacture cost.2nd, because the non-woven fabrics for medical bandage and amenities had both required fine air permeability and smooth
Degree, requires good elasticity again, while price is low, and disclosure satisfy that the elasticity of the bottom non-woven fabrics of above-mentioned requirements very
It is small, it is substantially negligible and disregards, but the compound nonwoven cloth in medical bandage and amenities needed for paper diaper waistline was then both
Flatness is required to meet, the flexible requirement of strong elastic is required to meet again, elastic hole drilling ventilation film exists for this utility model
Air-permeable elastic folding crape formula compound nonwoven cloth is formed with the compound rear resilience of bottom non-woven fabrics hot pressing in the state of stretching, had both met doctor
With the requirement of ventilative, smooth, the elastic colligation of bandage, meet what smooth, ventilative, strong elastic needed for paper diaper waistline stretched again
It is required that.3rd, the negative pressure suction inlet that air-vent shapes in elastic membrane is that technology of the present utility model is special along the design for being in boss mouth structure
The three of sign.The purpose so designed is：Elastic film surface by negative pressure ventilation during being punched, the negative pressure in its elastic film surface
Suction hole（Negative pressure air-out one end）Aperture along be in boss mouth, the boss platform just just as cloth supports in the multiple hole shapes of elastic film surface,
This works as itself and bottom non-woven fabrics hot pressing compound tense because the orifice part of hole shape support is higher than film surface so that bottom non-woven fabrics
Formed compound between face and the boss oral area of elastic film surface, not only greatly reduce nonwoven cloth cover and the composite surface of elastic membrane
Accumulate, and make the hollow multi-point support for multichannel being formed between bottom nonwoven cloth cover and elastic membrane and road road communicates, not only gas permeability
It is splendid, and telescopic resilience is good, starts the precedent for making the penetrating compound nonwoven cloth of hollow multi-point support.
Technical scheme：A kind of ventilative folding crape formula compound nonwoven cloth of elastic hollow, including non-woven fabrics, the film surface of elastic membrane have very
Have many air-vents and air-vent aperture along be in boss mouth more, elastic membrane in a stretched state the boss mouth on its elastic film surface and
Resilience forms the ventilative folding crape formula compound nonwoven cloth of elastic hollow after bottom non-woven fabrics hot pressing is compound.
The utility model is compared with background technology, first, without PUR, you can realizes bottom 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；Second, the design of open-celled flexible film, no
Elastic membrane extensibility is greatly increased, and there is the characteristics of high-tension, big expansion and contraction；Third, aperture boss in elastic membrane
Design, realize the compound of bottom non-woven fabrics and elastic membrane boss orifice part, not only make multiple non-woven fabrics have up and down, left and right,
Front and rear ventilative function and gas permeability is splendid, and telescopic resilience is good, starts and makes the penetrating compound nonwoven cloth of hollow multi-point support
Precedent.
