A method of charging a nonwoven web of thermoplastic microfibers to provide electret filter media is provided. The method includes impinging on a nonwoven web of thermoplastic nonconductive microfibers capable of having a high quantity of trapped charge jets of water or a stream of water droplets at a pressure sufficient to provide the web with filtration enhancing electret charge and drying said web.

The invention relates to a method for reducing the pilling behaviour of a fabric containing or consisting of man-made cellulosic fibers, wherein said fabric is treated by the following sequence: Impregnation of the fabric with an aqueous liquor containing at least one kind of acid for a period of 1 to 20 min at between 10 and 30°C, steaming of the impregnated fabric for a period of 2 to 20 min at between 90 and 100°C and washing the fabric neutral. Another aspect of the invention is a fabric containing or consisting of lyocell fibers showing an elongation at break (conditioned) of between 2.9 % and 5.0 % for the manufacture of a fabric with a pilling grade of equal or higher than 3, that was not crosslinked or resin-treated, as well as the use of this fabric.
摘要:
There is provided an impregnated natural fiber including a cuticle and an interior lumen, the cuticle circumscribing the interior lumen; and insoluble particulates possessing a preselected property embedded in the fiber. The particulates comprise at least 0.1-30 wt.% of the impregnated fiber and the particulates are embedded on the cuticle and within the lumen of the fiber. The fiber has an increased strength, micronaire value and rate of water absorption. Also provided is a system for surface treating cellulose sliver fibers. The system includes a vessel containing a moist paste which comprises at least one particulate material possessing one or more preselected desired properties, a thickening agent and water. The paste from the vessel is dispensed directly onto sliver fiber ribbon(s). A bore sonotrode generates ultrasonic waves which embed the particulate material(s) in the sliver fibers.
