Buffered non-formaldehyde durable press textile treatment
First Claim
1. A process for imparting durable press properties to a textile fabric formed at least partially of cellulosic fibers and characterized by avoiding the use of formaldehyde and problems associated therewith, said method comprising impregnating the textile fabric with a formaldehyde-free finishing agent containing glyoxal, reactive silicone, a catalyst, and a buffering agent for reducing acidity in the treated fabric, and thereafter drying the fabric and curing the finishing agent to impart durable press properties to the fabric.

Abstract
This invention relates to a durable press treatment for textile fabrics containing cellulosic fibers and which is characterized by avoiding the use of formaldehyde and problems associated therewith. The fabric is impregnated with a formaldehyde-free finishing agent containing glyoxal, reactive silicone, a catalyst and a buffering agent for reducing the acidity of the fabric. The fabric is thereafter dried and the finishing agent is cured to impart durable press properties to the fabric.

- 7. A process for imparting durable press properties to a textile fabric formed at least partially of cellulosic fibers and characterized by avoiding the use of formaldehyde and problems associated therewith, said method comprising impregnating the fabric with a formaldehyde-free finishing agent comprising glyoxal, reactive silicone, a durable press catalyst, and a salt of a weak acid and a strong base, drying the impregnated fabric, and heating the fabric to effect curing of the finishing agent and to impart durable press properties to the fabric.
- 11. A cured durable press textile fabric formed at least partially of cellulosic fibers, said fabric containing glyoxal and reactive silicone as fiber treating agents for said cellulosic fibers and imparting durable press properties to the fabric, and said fabric also containing a buffering agent for reducing the fabric acidity.
-
12. A treated textile fabric formed at least partially of cellulosic fibers and adapted for being cured by heating to impart durable press properties to the fabric but without the use of formaldehyde and problems associated therewith, said textile fabric containing an uncured formaldehyde-free finishing agent including as fiber treating agents a mixture of glyoxal and reactive silicone, and said fabric also containing a buffering agent for reducing the fabric acidity.
- 15. A non-formaldehyde finishing agent for imparting durable press properties to a textile fabric formed at least partially of cellulosic fibers, said finishing agent comprising a formaldehyde-free aqueous composition containing glyoxal, reactive silicone, a durable press catalyst, and a buffering agent for reducing acidity in the treated fabric.
