Abstract

The utility model discloses a PE (polyethylene) copolymerized PP (polypropylene) non-woven fabric, which is characterized in that: comprises a PE-PP copolymerization layer positioned in the middle, a PE layer positioned on one side of the PE-PP copolymerization layer, and a PP layer positioned on the other side of the PE-PP copolymerization layer. The bottom layer PP material is flat and smooth after being subjected to Wen Gaojing hot pressing, the printing surface leveling requirement is met, the PE material of the surface layer is stable and low in forming process due to low temperature resistance, the surface layer of the finished cloth is not hard in handfeel, the PE material is smooth, the effect of soft surface handfeel is achieved, and the requirement of customers on soft and soft touch feeling of non-woven fabrics can be met. When the composite material is compounded with other materials by secondary hot pressing, if the composite material is PE material, the PE material surface is used as a composite functional layer, and when the composite material is PP material, the PP material layer is used as a composite functional layer; can better meet the hot-pressing composite requirements of different materials.

Description

PE (polyethylene) co-PP (polypropylene) non-woven fabric

Technical Field

The utility model relates to the field of non-woven fabrics, in particular to a non-woven fabric formed by three die heads.

Background

In the prior art, the non-woven fabric is mainly made of PP (polypropylene) materials, and when the non-woven fabric needs to be hot-pressed with other materials PE and BOPP, the non-woven fabric has the problems of insufficient fastness and the like due to too high temperature. Meanwhile, after the compound fastness is achieved through the excessively high temperature, the problem that the hand feeling of the surface of the non-woven fabric is hardened due to the high temperature is caused.

Disclosure of Invention

The utility model mainly aims to provide PE (polyethylene) co-PP non-woven fabric.

The technical scheme adopted for solving the technical problems is as follows:

a PE copolymerized PP non-woven fabric comprises a PE-PP copolymerized layer in the middle, a PE layer on one side of the PE-PP (polyethylene-polypropylene) copolymerized layer, and a PP layer on the other side of the PE-PP copolymerized layer.

In a preferred embodiment: the gram weight range of the PE-PP copolymer layer is 2-20g/m ² 。

In a preferred embodiment: the gram weight of the PE (polyethylene) layer is 5-30g/m ² 。

In a preferred embodiment: the gram weight of the PP (polypropylene) layer is 5-30g/m ² 。

Compared with the background technology, the technical proposal of the utility model has the following advantages:

in the forming process, the bottom layer PP material is flat and smooth after being subjected to Wen Gaojing hot pressing, the printing surface leveling requirement is met, the PE material of the surface layer is low in temperature resistance, the forming process is stable and low, the surface layer of the formed cloth is not hard in handfeel, the PE material is smooth, the effect of soft surface handfeel is achieved, and the requirement of customers on soft and soft touch feeling of non-woven fabrics can be met. When the composite material is compounded with other materials by secondary hot pressing, if the composite material is PE material, the PE material surface is used as a composite functional layer, and when the composite material is PP material, the PP material layer is used as a composite functional layer; can better meet the hot-pressing composite requirements of different materials.

Detailed Description

A PE copolymerized PP non-woven fabric comprises a PE-PP copolymerized layer 2 positioned in the middle, a PE layer 3 positioned on one side of the PE-PP (polyethylene-polypropylene) copolymerized layer, and a PP layer 1 positioned on the other side of the PE-PP copolymerized layer.

The gram weight range of the PE-PP copolymer layer is 2-20g/m ² . The PE-PP copolymer is in the prior art, for example, CN202010773115.X discloses a high-smoothness PP and PE extinction master batch, a preparation method and application thereof; CN202110565026.0 discloses a process and device for preparing PP/PE low-melting point composite fiber; CN202010500207.0 discloses a method for improving wear-resistant and skin-friendly properties of PP-PE composite nonwoven fabric. The PE-PP copolymer materials are disclosed above.

The gram weight of the PE (polyethylene) layer is 5-30g/m ² 。

The gram weight of the PP (polypropylene) layer is 5-30g/m ² 。

In the forming process, the bottom layer PP material is flat and smooth after being subjected to Wen Gaojing hot pressing, the printing surface leveling requirement is met, the PE material of the surface layer is low in temperature resistance, the forming process is stable and low, the surface layer of the formed cloth is not hard in handfeel, the PE material is smooth, the effect of soft surface handfeel is achieved, and the requirement of customers on soft and soft touch feeling of non-woven fabrics can be met. When the composite material needs to be subjected to secondary hot pressing and compounding with other materials, referring to fig. 2, if the composite material is PE material 1', a PE material surface is used as a composite functional layer; referring to fig. 3, the PP material layer 3' is used as a composite functional layer when the composite material is a PP material composite; can better meet the hot-pressing composite requirements of different materials.
