Novel elastic waistline non-woven fabric and forming process thereof

Abstract

The invention relates to the field of hygienic product production raw materials, in particular to a novel elastic waistline non-woven fabric which comprises an upper elastic non-woven fabric layer, a lower elastic non-woven fabric layer and an elastic element clamped between the upper elastic non-woven fabric layer and the lower elastic non-woven fabric layer. The upper-layer elastic non-woven fabric is of a wavy-line-shaped structure with upper-layer wave crest parts and upper-layer wave trough parts which are arranged in a staggered mode in the thickness direction of the upper-layer elastic non-woven fabric, and the lower-layer elastic non-woven fabric is of a wavy-line-shaped structure with lower-layer wave crest parts and lower-layer wave trough parts which are arranged in a staggered mode in the thickness direction of the lower-layer elastic non-woven fabric, when the elastic elastic is in zero-tension natural state, the elastic element is compounded on the upper-layer wave trough parts and the lower-layer wave trough parts, the compounding positions of the upper-layer wave trough parts and the lower-layer wave trough parts correspond to each other, and the upper-layer wave trough parts and the lower-layer wave trough parts are not in contact with the elastic element. The novel elastic waistline non-woven fabric provided by the invention has relatively high wearing comfort.

AI Technical Summary

Benefits of technology

This new type of material has three layers: an outer layer made up mostly of stretchy fibers that create space between them called the top part or core area for airflow through while keeping other parts dry out (wear). Another inner layer consists mainly of stiffened threads arranged like waves on regular lines within another plane. These elements help distribute pressure evenly across all areas inside this design without adding extra weight. It's comfortable because its surface feels smooth when worn by users due to its flexibility and impervious nature. Its technical effect lies in reducing manufacturing cost compared to traditional products.

Problems solved by technology

Technically speaking, there exist different types of elastomeric materials called Elasto® or ELASTANE (registered trademark), each having their own advantages and disadvantages when applied separately. These properties limit how well they work together at creating effective garments like diapers without causing them feeling too tightly around themselves. Additionally, these materials have low moisture vapor transmission rates making them difficult to breathe dry during use over longer periods compared to regular wovens.
