Why Hard Wadding And Glue-Free Wadding Is Widely Applied and Popular
Hard Wadding And Glue-Free Wadding: Hard wadding is manufactured by the hot air process. Compared with ordinary hot air cotton, it contains a higher proportion of low-melting fiber, with a relatively hard hand feel and a grammage generally ranging from 40 to 3000 grams per square meter. It is mainly white and can be made into sheets and coils. It is elastic, tough, wear-resistant, impact-resistant and tear-resistant, and is commonly used for car sofa cushions, mattresses and water beds.
The Influence of Card WireCloth Properties on Neps and Short Linters
The carding process targets the fiber layer (licker-in carding), fiber bundles (flat carding), and pseudo-neps within the fibers (cylinder and flat carding). Adjacent carding teeth in a carding machine are arranged in a crisscrossing or parallel configuration. The relative movement between the teeth occurs in different directions, interacting and generating impact, friction, and carding forces on the fibers. These forces penetrate and break down the fiber bundles into individual fibers, dissolving neps. Excessive or insufficient force will affect the carding teeth’s ability to grasp, card, release, and transfer fibers, leading to an increase in short linters and neps.
