Process for producing smooth-dry cellulosic fabric with durable softness and dyeability properties

The process for producing a differentially dyed, durably soft, smooth-dry cellulosic fabric comprising:

• (a) immersing a cellulosic yarn into a sufficient amount of an aqueous finishing solution comprising sufficient concentrations of N-methylol crosslinking agent, acid catalyst and alkyl bishydroxyethyl quaternary to impart smooth-dry performance and dye receptivity to the yarn;
• (b) drying the cellulosic yarn of (a) for sufficient time at sufficient temperature to remove moisture;
• (c) immersing another cellulosic yarn into a sufficient amount of an aqueous finishing solution comprising sufficient concentrations of:
• N-methylol crosslinking agent and acid catalyst to impart smooth-dry and dye-resist properties to the yarn;
• (d) drying the treated yarn of (c) for sufficient time at sufficient temperature to remove moisture;
• (e) combining yarn (b) with yarn (d) so as to produce a fabric with preselected dye resist and dye receptive areas;
• (f) curing the fabric at sufficient temperature for sufficient time to interact the finishing components with the fabric;
• and then;
• (g) dyeing the fabric with a cellulosic or other anionic dye thereby producing a differentially dyed, smooth-dry fabric with durable softening properties.

A process for producing a differentially dyed, durably soft, partially smooth-dry cellulosic fabric comprising:

• (a) immersing a cellulosic yarn into a sufficient amount of an aqueous finishing solution comprising sufficient concentrations of N-methylol crosslinking agent, acid catalyst and alkyl bishydroxyethyl quaternary to impart smooth-dry performance and dye receptivity to the yarn;
• (b) drying the cellulosic yarn of (a) for sufficient time at sufficient temperature to remove moisture;
• (c) combining the yarn of step (b) with an untreated yarn so as to produce a fabric with preselected dye resist and dye receptive areas when subjected to dyeing under acidic conditions;
• (d) curing the fabric at sufficient temperature for sufficient time to interact the finishing components with the fabric;
• and then,
• (e) dyeing the fabric with a cellulosic or other anionic dye in a mildly acidic dyebath thereby producing a differentially dyed, durably soft, partially smooth-dry fabric.

A process for producing a crossdyed, durably soft, partially smooth-dry cellulosic fabric comprising:

• (a) immersing a cellulosic yarn into a sufficient amount of an aqueous finishing solution comprising sufficient concentrations of N-Methylol crosslinking agent, acid catalyst and alkyl bishydroxyethyl quaternary to impart smooth-dry performance and dye receptivity to the yarn;
• (b) drying the cellulosic yarn of (a) for sufficient time at sufficient temperature to remove moisture;
• (c) combining the yarn of step (b) with an untreated yarn so as to produce a fabric with preselected dye resist and dye receptive areas when subjected to dyeing under acidic conditions;
• (d) curing the fabric at sufficient temperature for sufficient time to interact the finishing components with the fabric;
• (e) dyeing the fabric with a cellulosic or other anionic dye in a mildly acidic dyebath;
• (f) washing the fabric to remove unreacted dyestuff and then immersing the fabric in an alkaline dyebath containing reactive dyestuff of different color than that of step (e) for sufficient time to dye the fabric and thereby produce a bicolored, durably soft, partially smooth-dry cellulosic fabric.
