Discussion On The Properties Of Coated Nonwoven For S Cut Spunbonded Nonwoven

1. Spunbonded nonwovens

In the category of non woven fabrics, spunbond non woven fabrics are a relatively young variety, but their development is very rapid, and they have become one of the highest-yielding non-woven fabric varieties. The reason why the development of spunbonded nonwovens is so rapid is that it has the characteristics of short process flow, high product strength and relatively low cost, so its application fields are becoming wider and wider. It is not only closely related to people's life, but also has been used in all fields of national economy. Combined with the actual production process, in order to have a detailed understanding of spunbonded nonwovens and coated nonwovens, experiments were carried out on their morphological structure, physical properties, mechanical properties, air and moisture permeability and their characteristics. , Combined with the test results, it provides a certain reference value for further improving the quality of the product.

2. Features of Coated nonwoven for S cut

In this paper, 2 kinds of Coated nonwoven for S cut and 2 kinds of spunbond nonwovens are selected for testing. By measuring the performance and characteristics of these 4 kinds of nonwoven materials, the following conclusions can be drawn:

(1) White spunbonded nonwovens have good mechanical properties, and their breaking strength, elongation at break, and bursting strength are relatively large. This kind of spunbonded nonwovens is more commonly used in daily life. Generally used for packaging materials or shopping bags. The lightweight properties and good mechanical properties of polypropylene spunbond nonwovens make it an ideal raw material for these types of products.

(2) The spunbonded double-layer nonwoven fabric has a double-layer structure, which has good air permeability and moisture permeability. Although its mechanical properties and dimensional stability are very general, because of its unique structure, it filters impurities in the air It works well. Ordinary masks in daily life are made of spunbonded double-layer nonwovens as raw materials.

(3) Coated nonwoven for S cut has the worst mechanical properties, dimensional stability, and air and moisture permeability. However, it has very good impermeability properties. In the field of medical and health care, Coated nonwoven for S cut spunbonded nonwovens can be used as surgical gowns or protective clothing, with the outer coating, it has excellent permeability resistance, which can protect the human body from harmful substances damage.
