New application of elastic non-woven fabric

Elastic non-woven fabric is a brand-new non-woven product, which breaks the situation of air-impermeability, over-tightness, and small stretchability of elastic film materials. Following the previous part released yesterday, the next part of this article will continue to take you to understand the new applications of elastic non-woven fabrics in the field of mild incontinence products.


At present, there are various types of elastic materials, using various production processes and having different characteristics.


1. Elastic spandex yarn


High stretch recovery, the product is combined with the surface layer non-woven fabric to form a longitudinal stretch non-woven fabric, with mature technology and low cost.


2. Hot melt elastomer


The elastomer spinneret and the surface layer non-woven fabric are combined to form a longitudinal elastic non-woven fabric.


3. Four-sided stretch non-woven fabric/film


It is produced by imitating the sticking process, the elastomer spinneret is laid, the forming is wound, and the product is combined with the surface layer non-woven fabric to form a longitudinally stretched non-woven fabric;


It is produced by the two-component double-layer/multi-layer netting imitation bonding process. The longitudinal elasticity is activated during the production of the product, and it is combined with the surface layer non-woven fabric to form a longitudinally stretched non-woven fabric.





Horizontal elastic non-woven fabric series products


It is understood that most of the elastic non-woven fabrics currently focus on imparting elastic functions in structure and technology to improve the coating effect.


Horizontal elastic non-woven fabric presents the characteristics of textile elastic underwear fabric, excellent stretch recovery, cotton soft or silky touch, cotton or silk appearance.





Appearance of various elastic non-woven fabrics


The silk-like elastic non-woven fabric has a smooth surface and has the silky, soft and luster of silk fabric, which can meet the strength, concealment, adjustable luster, printing, etc. required by the underwear material.


Hand feeling of various elastic non-woven fabrics


The softness of the material depends on the surface non-woven fabric and the processing of the composite process, and a variety of different styles can be made.


The elastic properties of various elastic non-woven fabrics





The elastic non-woven fabric has wide stretchability, and the stretch strength of elastic underwear when worn by different body types is not much different, and it has good fit.


The figure below shows the smooth stretch recovery curve of a 70gsm transverse elastic non-woven fabric when stretched 100-150%.





Summary


It is understood that the cost of horizontal elastic non-woven fabrics for elastic underwear fabrics is only 1/3 of similar cotton textiles and 1/5 of silk products. With good mechanical cutting and bonding properties, it has greatly improved production efficiency through redesigning the process of underwear and apparel and automated production of equipment, and has become the preferred material for disposable underwear and other apparel.
