摘要:
A composite structure including at least one natural fiber web layer and at least one nonwoven web layer. In an exemplary embodiment, the natural fiber web layer is made of cotton fibers and the nonwoven web layer is a spunbond or spunmelt layer. The composite structure may be used to form components of an absorbent article, such as top sheets or back sheets of a diaper.
摘要:
A method of manufacturing a nonwoven including the steps of: forming a nonwoven web substantially comprised of continuous fibers; applying a bonding pattern to said nonwoven web using a smooth roll and a calender roll wherein said bonding pattern comprises a pattern having unbonded areas; and subjecting the side of said nonwoven web contacted by said smooth roll to a hydraulic treatment at a pressure of between 25 and 75 bars and a total energy of about 0.01-0.04 kwhr/kg., wherein said continuous fibers are comprised of between 97% and 98.5% by weight of an olefin resin comprising substantially of polypropylene and between 1.5% and 3% by weight of a whitener.
摘要:
A nonwoven web made of substantially continuous fibers and comprising a three-dimensional pattern of protruding closed shapes, wherein the nonwoven web has a compression recovery of at least 30% after being compressed at 1 psi for 24 hours.
摘要:
A nonwoven web including a first layer that includes continuous fibers having a first polymer component and a second layer that includes continuous fibers having a second polymer component. The melting point of the second polymer component is less than the melting point of the first polymer component, and the first layer is hydroentangled with the second layer.
摘要:
The present invention is directed to a nonwoven fabric made from a composite of nonwoven and pulp where the nonwoven has a high loft derived from a heat set three-dimensional relief structure and/or hydroengorged fiber structure. A nonwoven web is hydraulically treated to create a hydroengorged material having an increased loft. Alternatively a nonwoven web is treated to have a heat set three-dimensional relief structure. The treated web is then hydroentangled with pulp to form a cotendered nonwoven/pulp composite fabric.
