Abstract: The present invention relates to a process for the production of a nonwoven fabric. In particular, the present invention relates to the production of a nonwoven fabric having desirable tactile and haptic properties, as well as to the nonwoven fabric itself. The process requires the selection of specific materials and process conditions. The fabric is produced from a masterbatch of isotactic polypropylene homopolymer and a surface-treated calcium carbonate filler.

Abstract: Disclosed are methods and devices for forming a combined polyester and fiberglass mat, in which separate polyester and fiberglass layers can be formed or polyester filaments and fiberglass threads can be mixed together by a disperser to form a polyester and fiberglass web. The polyester filaments and the fiberglass threads can be dispersed by separate dispersers on a web forming belt to form separate layers of polyester filaments and fiberglass threads, or can be dispersed by a single disperser to at least, somewhat evenly disperse, the fiberglass threads and polyester filaments.

Abstract: A method of preparing an electret by saturating a nonwoven fabric with a liquid, such as water, and removing the liquid via suction to generate charges by friction between the fabric fibers and the liquid is described. The saturating can be carried out, for example, by impinging the bottom side of the fabric with a jet or jets of water while the fabric is being pulled under a solid roller. Excess water can also be applied during a water quenching step of a meltblowing or spunbonding process. An apparatus for preparing an electret according to the presently disclosed methods is also described.
