Abstract:

In order solve the problems of difficult degradation of disposable moist wipes after use and easy blockage of the drainage pipe, the new dispersible and biodegradable wetlaid/hydroentanglement materials for moist wipes were introduced in terms of preparation technology, fiber composition, material attributes and application. Meanwhile, the material structure characteristics and properties (wet strength, dispersion and handling) were compared and analyzed. The results show that the material composed of long and short fiber entanglements and has the attributes of both nonwoven and paper. Moreover, long fiber (short cut regenerated cellulose) entanglements as fiber reinforcement influence the wet strength and dispersibility of the mateiral, and the material hand ling is close to the carding/hydroentanglement nonwoven. Finally, the development trend of materials, including reinforced fiber optimization, application of auxiliary reinforcement and equipment process improvement, were systematically expounded.
