| Abstract: |
The pilling propensity of knit fabric from polyester staple fiber can be reduced by scouring the fabric at a temperature in the range of about 160.degree. to 205.degree. F. for from about 15 to 60 minutes in a 0.3 to 1.0% aqueous caustic solution containing about 0.001 to 0.1% of a quaternary ammonium salt of the formula: ##STR1## wherein R is an alkylene radical of 2 to 3 carbon atoms, R' is H or phenyl, R" is a C.sub.12 -C.sub.18 hydrocarbon radical, x is 2 or 3, y is 0 to 3, and Z.sup.- is an anion, preferably the dimethyl sulfate quaternary ammonium salt of bis(hydroxy-tri-1,2-propyleneoxy-2-ethyl)tallowamine. After scouring, the fabric is normally rinsed, neutralized, rinsed again and dried. |
