    Abstract: A FILAMENT, HAVING IMPROVED RESISTANCE TO SOILING, OF A SYNTHETIC POLYMER HAVING MIXED THERETHROUGH ABOUT 0.02 TO 5 WEIGHT PERCENT, BASED ON THE WEIGHT OF THE SYNTHETIC POLYMER, OF AN AMIDE HAVING THE GENERAL FORMULA;

    BIS-((CH3-R-CO-NH-(CH2)X-)2-N-CO-(CH2)N-)BENZENE

    WHEREIN THE HEXAGON REPRESENTS THE BENZENE NUCLEUS, R IS A DIVALENT RADICAL CONTAINING UP TO ABOUT 30, PREFERABLY ABOUT 3 TO 18, CARBON ATOMS WHICH CAN BE LINEAR OR BRANCHED ALIPHATIC, N IS AN INTEGER FROM 0 TO ABOUT 6 BUT PREFERABLY IS 0, X IS AN INTEGER FROM 1 TO ABOUT 6 BUT PREFERABLY IS ABOUT 2 TO 3, AND THE

    -(CH2)N-CO-

    RADICALS CONNECTED TO THE BENZENE NUCLEUS ARE RELATIVELY DISPOSED IN THE ORTHO, META, OR PARA POSITIONS BUT PREFERABLY IN THE META POSITION.

    Abstract: Nonwoven web materials are formed from multiconstituent filaments having the ability to self-bond without substantial polymer flow, disfiguration, or cross-sectional flattening when heat-treated, said multiconstituent filaments being spun from at least two different polymeric materials such that, in a given filament, a first fiber-forming polymeric material defines a matrix and a second polymeric material is dispersed therein in the form of discontinuous fibrils, said matrix comprising at least 50 percent by weight of the filament and having a lower melting point than said dispersed fibrils. The multiconstituent filaments may be combined with other fibrous or additive materials in a variety of ways depending on the use intended for the web.
