Method Of Improving Leak Guard SMMS Meltblown Non Woven Fabric

With the improvement of people's living standards and the continuous enhancement of hygiene awareness, disposable hygiene products are more and more commonly used. As one of the main raw materials used in the field of hygiene products, non woven fabrics have also developed rapidly. This paper analyzes the existing problems of leak guard SMMS meltblown non woven fabric, and proposes methods to improve leak guard SMMS meltblown non woven fabric, which provides a positive reference for its further development.

1. Problems with leak guard SMMS meltblown non woven fabric

At present, most sanitary napkins and baby diapers have two-wing three-dimensional anti-side leakage made of leak guard SMMS meltblown non woven fabric, after applying structural adhesive and elastic rubber, and then wrapping multiple elastic bands and folding them. However, in the production of sanitary napkins and baby diapers, since the elastic and thin elastic elastic bands are placed, the elastic bands are easily broken, and the number of waste discharge pieces caused by the rupture of the elastic bands is more than 100 pieces at least, resulting in Raw material waste.

2. How to improve leak guard SMMS meltblown non woven fabric

In view of the existing problems at this stage, this paper proposes an elastic leak guard SMMS meltblown non woven fabric with reasonable structural design, good comfort, high yield of finished products and reduced production cost.

Its components are: water-repellent non-woven fabric, structural adhesive, PE elastic film. The specific design is that one end of the water-repellent non-woven fabric is folded up or down into a U-shape, the PE elastic film is placed in the U-shaped area of the water-repellent non-woven fabric, and the PE elastic film is bonded to the water-repellent non-woven fabric through structural adhesive. Taken together, the PE elastic film is a flat rectangle, the width of the PE elastic film is smaller than the width of the folded edge of the non-woven fabric, and the water-repellent non-woven fabric and the folded edge of the non-woven fabric are also tightly bonded by structural adhesive. The PE elastic film is centered and built in the U-shaped area of the water-repellent non-woven fabric, and the water-repellent non-woven fabric, the PE elastic film, and the folded edges of the non-woven fabric are arranged in parallel.

The beneficial effects that the three-dimensional enclosure can provide are: the three-dimensional enclosure is made of water-repellent non-woven fabric, applying structural adhesive at one time, and superimposing one

A layer of PE elastic film of appropriate width is folded and wrapped by a water-repellent non-woven fabric. In the elastic three-dimensional protective non-woven material

The PE elastic material has the advantages of being not easy to break, soft and moderately elastic, thereby reducing the waste rate of sanitary napkins and baby diapers, increasing the comfort of use, and eliminating the need for elastic rubber, which saves sanitary napkins , The production cost of baby diapers.

The application of spunmelt non woven fabrics in personal care and other hygiene materials is more and more extensive, especially in the application of the surface layer and bottom film of diapers and sanitary napkins. Understanding the current problems of leak guard smms meltblown non woven fabric, and the method of improving SMMS non woven fabric, is conducive to its better development.
