    • The method of treating a textile fabric comprising cellulosic fibers to produce a modified fabric intermediate from which permanently shaped wearing apparel having an improved dry crease recovery can be made, comprising the steps of: (1) impregnating the material with a cellulose cross-linking reagent selected from the groups consisting of: (a) reaction products of formaldehyde with carboxamides wherein said reaction products contain 2 or 3 N-methylol groups and methyl ethers thereof; (b) compounds having the following generic formula:R.sub.1 OCH.sub.2 CH.sub.2 SO.sub.2 (QSO.sub.2).sub.n CH.sub.2 CH.sub.2 OR.sub.2where R.sub.1 and R.sub.2 are selected from the group consisting of hydrogen and an alkyl radical of up to five carbon atoms; Q is a divalent organic radical selected from the group consisting of aliphatic radicals containing at least three carbon atoms, aromatic radicals and aklylaromatic radicals; and n is 0 or 1, and said reaction conditions include the presence of an alkaline catalyst; (c) compounds have the following generic formula: ##STR1## where R.sub.1, R.sub.2, and R.sub.3 are selected from the group consisting of hydrogen and alkyl radicals having up to five carbon atoms; Q is a divalent organic radical; W is an electronegative activating group such as --CO--, --CONH, and the like; and n has a value of 0 or 1; and (d) compounds having 2 or 3 N-hydroxypropyl groups and methyl ethers thereof; (2) heating the impregnated fabric in an atmosphere in which the relative humidity is less than 100% in the presence of a catalyst to a temperature for a time sufficient to chemically bond the cross-linking reagent to the cellulosic fibers, thereby producing the modified fabric intermediate in which the reacted cross-linking reagent is insolubilized to the extent that the reacted reagent would not be removed by washing the fabric, the modified fabric intermediate having a dry crease recovery angle which is increased by at least 10% by subsequently heating the fabric.
