Abstract:
The present invention provides a method for producing softer fibers and nonwoven webs that includes forming a mixture comprising (i) a thermoplastic and (ii) an additive selected from the group consisting of polyethylene waxes, glyceryl monostearate, sorbitan tristearate, CATALLOY KS357 MONTELL polyolefin resin, an amide having the chemical structure CH3(CH2)7CHnullCH(CH2)xCONH2 where x is selected from 5-15 and mixtures thereof; forming the mixture into fibers and optionally creating a nonwoven web.
Abstract:
New methods for and patterns of applying meltsprayed materials in single-layer web and laminate constructions so as to control various characteristics in the webs and laminates is provided. The patterns of adhesive produce scrim or cell-like patterns that allow for control of desirable characteristics. For example, the loft of a laminate may be enhanced, as well as strength properties.
