Biodegradable non-woven materials with fluid management properties and disposable absorbent products containing the same

摘要

"BIODESINTEGRABLE NON-BRAIDED MATERIALS WITH FLUID MANAGEMENT PROPERTIES AND DISPOSABLE ABSORBENT PRODUCTS CONTAINING THE SAME". a bio-disintegrable nonwoven material having improved fluid management properties is disclosed. Biodegradable non-woven material demonstrates higher contact angle hysteresis, shorter entry times, improved skin dryness compared to prior art non-woven materials. In addition, biodegradable nonwoven materials also exhibit high rates of humidification, which is unexpected based on high hysteresis values. The nonwoven material can be produced using thermoplastic compositions that comprise an unreacted blend of aliphatic polyester polymer with a continuous phase, polyolefinic microfibers with a discontinuous phase embedded within the continuous phase of the aliphatic polyester polymer, and a compatibilizer for the aliphatic polyester polymer and polyolefinic microfibers. The multicomponent fiber exhibits substantial biodesintegration properties and good humidification capacity while still being easily processed. Biodegradable non-woven materials can be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
