摘要： The invention relates to a polymer fibre with improved dispersibility, a method for producing said fibre and the use of said fibre. The polymer fibre according to the invention comprises at least one synthetic polymer and 0.1 and 20 wt. % of a silicone. The polymer forming the fibre forms a solid dispersion medium at room temperature (25° C.) for the silicone present in solid form also at room temperature (25° C.) which forms the more disperse phase. The polymer fibre according to the invention possesses an improved dispersibility and is therefore suitable for producing aqueous suspensions which are used, for example, in the formation of textile fabrics, e.g. nonwovens.

摘要： A non-woven functional core cover for use in combination with an absorbent core, where said functional core cover comprises at least a first fraction comprising lyocell fibres, and characterised in that a majority of said fibres are oriented in the same direction. Thus, the absorbent core cover may be considered an absorbent article component. Thereby, a functional core cover having improved wicking properties and improved wet integrity is realised, the advantages allowing reducing the amount of fluff used in the mix with SAP. A reduction of material used in the absorbent core improves the feeling of wearing the absorbent product, e.g. a baby diaper, which in turn facilitate the movement of the baby. The wicking properties cause liquid to be distributed better across the surface of the core cover, such that more of the absorbent core is exposed to the expelled liquid.

摘要： Described herein is a continuous process for modifying the properties of polyester and polyester based fibers, such as a poly(butylene terephthalate) (PBT) fiber, comprising subjecting the PBT fiber to alkaline hydrolysis, and optionally further comprising functionalizing the PBT fiber by solution grafting such as fluorination. The alkaline hydrolysis and optionally subsequent functionalization such as fluorination process can be continuous, following the melt blowing/spinning or spun-bonding process. Also described is a nonwoven PBT fiber mat obtained by the surface modification process. Further described is a filtration device comprising the nonwoven PBT fiber mat.
