“…The group that the nonwoven fabrics are needle punched at 9 mm has the maximum puncture strength. This result is contrary to our expectation as within a certain range of needle punch, the mechanical properties increase as a result of a greater needle punch depth [44]. In addition, all of the composites have comparable puncture strength.…”

The study employs the mechanical interlocking theory and hot pressing treatment to generate nonimpregnation of highly rebounding composites. This design preserves the high flexibility, elasticity, and stability of elastic polymer while reserving the skin-friendly feature, resilience, and recovery of the highly elastic nonwoven fabrics without using an adhesive. During the preparation of highly rebounding composites, elastic polymers are hot pressed to form films, after which they are combined with highly elastic nonwoven fabrics. The composites are then examined in terms of the mechanical properties and the level of adhesion. Fluffy nonwoven fabrics and elastomer polymers are hot pressed in order to obtain better adhesion and puncture resistance. The tensile and hammer rebound rate test results show that highly rebounding composites that are reinforced using stiff nonwoven fabrics exhibit greater resilient and tensile properties. Comparing to pure nonwoven fabrics, the proposed highly rebounding composites have a structure that is 1.5 time greater compactness, as well as 1.5 times greater a tensile strength and 1.6 time greater resilience. Namely, they provide great variety according to the users’ ends as their performances are better and adjustable. For example, shallowly or deeply needle punched nonwoven fabrics can be separately used in the garments or cushions. The proposed highly rebounding cushion composites are protective materials and are suitable for the application as in cushions, packaging, and buffering protective equipment.

Wet-laid hydroentangled nonwovens are widely used for disposable products, but these products generally do not have good dispersibility and can block sewage systems after being discarded into toilets. In this study, both pulp fibers and Danufil fibers are selected as we hypothesize that the high wet strength and striated surface of Danufil fibers would allow us to produce nonwovens with better dispersibility while having enough mechanical properties. The wet strength and dispersibility of nonwovens are systematically studied by investigating the influence of the fiber blend ratio, fiber length, and water jet pressure. The results indicate that the percent dispersion could be as high as 81.3% when the wet strength is higher than 4.8 N, which has been improved greatly comparing the percent dispersion of 67.6% reported before.
