Embodiment 1

[0009] A kind of non-woven material and its processing method. It is processed by four layers of material. Two layers of spunbonded non-woven fabrics are sandwiched between melt-blown non-woven fabrics to make SMS composite non-woven fabrics according to the SMS composite production process, and then the film is used Technology Composite waterproof and breathable film on SMS composite non-woven fabric to make four-layer spunmelt hydrophilic and anti-penetration non-woven material. It is made after feeding, melting, filtering, metering, spinning, drawing and cooling, web forming, hot air bonding and winding. The raw material of the first layer of spunbond non-woven fabric (S) is isotactic polypropylene with low melting point (32-38g / 10min), which is sprayed first, and skin-friendly and hydrophilic with FDA certification (food certification) are added to the fiber filaments. Oil agent, so that the fiber fineness reaches 1.1dtex-3dtex, and the single layer weight reaches 9-12g / m ...

Embodiment 2

[0012] (1) Put polypropylene slices with a melt index of 32-38g / 10min into No. 1 suction system; put polypropylene slices with a melt index of 1200g / 10min and hydrophilic masterbatches into No. 2 at a ratio of 96:4 Suction system; put polypropylene chips with a melt index of 32-38g / 10min into the No. 3 suction system; mix the hydrophilic oil agent with water at a ratio of 10:60 and put it into the spray system;

[0013] (2) According to the spunbond spray process + melt blown process + spunbond production process, the prepared raw materials are made after feeding, melting, filtering, metering, spinning, drawing cooling, web forming, hot air bonding and winding .

Embodiment 3

[0015] (1) Put polypropylene slices with a melt index of 32-38g / 10min into the No. 1 suction system; put polypropylene slices with a melt index of 1200g / 10min and hydrophilic masterbatches into No. 2 at a ratio of 96:5 Suction system; put polypropylene slices with a melt index of 32-38g / 10min into the No. 3 suction system; mix the hydrophilic oil agent with water at a ratio of 12:48 and put it into the spray system;

[0016] (2) According to the spunbond spray process + melt blown process + spunbond production process, the prepared raw materials are made after feeding, melting, filtering, metering, spinning, drawing cooling, web forming, hot air bonding and winding .

[0017] Adding the raw materials formulated according to the above ratio can effectively ensure the stability of the spunbond production process and ensure the safety of the product in terms of comfort and safety.

Abstract

The invention provides a non-woven material and a processing method thereof. The non-woven material is produced by processing 4 layers of materials, melt-blown nonwovens are placed between two layers of spunbond nonwovens to produce SMS compound nonwovens in accordance with SMS compound manufacturing technique, then the laminating technology is adopted to compound waterproof breathable layers on the SMS compound nonwovens to produce four layers of spunmelt hydrophilic anti-infiltration non-woven material, the non-woven material is finally made after going through the steps such as feeding, meltdown, filtration, measurement, spinning, stretching, cooling, web formation, hot air air-thru bonding and winding; the non-woven material is flexible, safe, sanitary and cheap, thus being widely applied in hospitals, nursing rooms, hotels and other hygiene medical systems.

Description

Technical field: [0001] The invention relates to a nonwoven material, in particular to a soft and elastic four-layer composite spunmelt hydrophilic anti-permeation nonwoven material and a processing method thereof. Background technique: [0002] With the improvement of people's living standards, people pay more and more attention to medical safety and personal hygiene, and the use of disposable medical supplies and sanitary supplies is also increasing. The use of disposable medical surgical sheets and bed sheets for inpatients reduces the workload of patient care and the most important thing is to prevent cross-infection of patients and bring safety to the doctor and treatment; another hotel, guesthouse, restaurant, etc. once The use of non-toxic bed sheets, sofa cushions, cushions, disposable slippers, etc. not only bring people a comfortable feeling for travel and dining, but also meet people's hygiene requirements and prevent the spread of certain contact diseases.
