Description
Technical field
The utility model is related to it is a kind of both without PUR, without stretched non-woven cloth, nonwoven strip, just can by surface layer without
Spin cloth and bottom non-woven fabrics or nonwoven strip is compounded in air-permeable elastic film two sides or both sides under air-permeable elastic film stretching state, and
And can shape to be formed as the resilience of air-permeable elastic film resets needed for air-permeable elastic arc folding crape formula compound nonwoven cloth or folding crape formula
Lateral leakage protection non-woven fabric production line, it is mainly used in medical bandage, sanitary napkin, paper diaper, belongs 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
Ventilated membrane is combined.The air-permeable elastic film is polyurethane film.Elastic non-woven cloth and the air-permeable elastic film is by bonding
Agent is combined.Described adhesive is PUR.Elastic non-woven cloth and elastic polyurethane ventilated membrane are equal when carrying out composition operation
In extended state, the automatic retracted after the completion of compound.Its weak point：First, need bullet during the compound nonwoven cloth composite molding
Property non-woven fabrics and elastic polyurethane ventilated membrane in extended state complete compound, the air-permeable elastic of the non-woven fabrics after composite molding
The elasticity of film is restricted by elasticity by elastic non-woven cloth, and what is obtained is the compound nonwoven cloth being limited with elastic non-woven cloth elasticity, its
Elasticity is very limited；Second, the complex dependence of elastic non-woven cloth and elastic polyurethane ventilated membrane is in PUR, and the base of PUR
This resin is the EVA resin that ethene and vinyl acetate are copolymerized at high temperature under high pressure, and the viscosity of EVA resin itself is very low,
Tackifier, such as modified rosin need to be added（138 or 145）, C5 Petropols, C9 Petropols, terpene resin etc., these compositions
The viscosity enhancing for causing PUR is added, but during its complex media as elastic non-woven cloth and elastic polyurethane ventilated membrane, but
The gas permeability of elastic non-woven cloth is plugged significantly, substantially reduces the gas permeability of the compound nonwoven cloth after composite molding, or even very
Difference.
The application all formerly patent CN102302400 B, titles " elastic ventilated full waist plaster and preparation method ", elastic force leads to
The former of the full waist patch of gas, it includes blown film mechanism, and blown film mechanism mouthpiece both sides are respectively equipped with herringbone shaping membrane guide roller stand
And the outlet directly import to elastic membrane format roll of herringbone shaping membrane guide roller stand, elastic membrane format roll are exported directly to blade cutting edge
The import of format roll, the outlet of blade cutting edge moulding roller are directly molded the import of composite roll to wrinkle, wrinkle shaping composite roll
It is wind-up roll to export opposite.The equipment uses blown film mechanism, thus its shaping membrane guide roller stand 5, film format roll 6, edge are molded
Roller 7, wrinkle shaping composite roll and wind-up roll are vertically arranged.Its weak point：It is compound on its film surface to be not easy to non-woven fabrics.
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, nonwoven strip, just can by surface layer non-woven fabrics and bottom non-woven fabrics or nonwoven strip under air-permeable elastic film stretching state it is compound
On air-permeable elastic film two sides or both sides, and can shape to be formed as the resilience of air-permeable elastic film resets needed for air-permeable elastic arc
Crape formula compound nonwoven cloth or folding crape formula lateral leakage protection non-woven fabric production line are rolled over, is mainly used in medical bandage, sanitary napkin, paper diaper.
Design：In order to realize above-mentioned purpose of design.The utility model is in structure design：1st, the film of air-permeable elastic film
There is the design of many air-vents in face, is one of the technical characteristics of the utility model.The purpose so designed is：Due to this practicality
New the air-permeable elastic film and non-woven fabrics are complex as no glue（Without PUR）It is compound, i.e. the film surface and nonwoven of air-permeable elastic film
