Elastic nonwovens are a rare special material. Lai Chi's elastic non-woven technology does not incorporate elastic rubber. The elasticity of the elastic non-woven fabric is the memory of the fiber positioning, which produces the pulling force; therefore, the unique point of this elastic non-woven fabric is that it has a high ductility of more than 200% and a gentle retractive force. . Such high ductility and low tensile strength properties are applied to many products, allowing the wearer to fit and eliminate the strain or allergies caused by the elastic band.
