Spandex yarn features:

Spandex Yarn is specially designed soft synthetic polymer which is stronger, lighter and more versatile and used to improve the fit of the diaper.

Spandex Yarn plays a key role in disposable hygiene products such as diapers, sanitary napkins, adult incontinence products, etc., mainly used to provide elasticity, fit, and comfort. The following are its specific applications and technical characteristics:
1. Core application scenarios
(1) Waistband elastic system
Function: Ensure that the diaper/pants hygiene product fits snugly around the waist to prevent slipping or leakage of urine.
Design Form:
Full waist elasticity: Spandex yarn is blended with PP/PE fibers to provide uniform stretchability.
Localized elasticity enhancement: Increase spandex content on both sides of the waist or key areas of the back waist to enhance support.
(2) Leg Cuffs
Function: Adhere to the base of the thigh to prevent lateral leakage.
Technical points:
Double layer elastic structure: outer non-woven fabric+inner spandex yarn composite, adjustable elasticity.
Dynamic Fit: The high rebound rate (>500%) of spandex adapts to the deformation of babies during activities.
(3) Stretch Tabs

Function: In traditional adhesive diapers, adding spandex yarn to the side waistband can enhance stretching and recovery capabilities, avoiding tight or loose adhesion.
