  • Durable press process
    Patent number: 4108598
    Abstract: Cellulosic fiber-containing fabrics are made wrinkle resistant by a durable press process which comprises treating a cellulosic fiber-containing fabric with aqueous formaldehyde and a catalyst capable of catalyzing the cross-linking reaction between the formaldehyde and cellulose, heat-curing the treated cellulose fiber-containing fabric, preferably having a moisture content of more than 20% by weight, under conditions at which formaldehyde reacts with cellulose in the presence of the catalyst without a substantial loss of formaldehyde before the reaction of the formaldehyde with cellulose to improve the wrinkle resistance of the fabric.

  • Durable press process employing alkyl sulfonic or sulfuric acid
    Patent number: 3960483
    Abstract: Cellulosic fiber-containing fabrics are made wrinkle resistant by a durable press process which comprises impregnating the fabric with an aqueous solution containing an alkyl sulfonic acid or sulfuric acid, capable of catalyzing the cross-linking reaction between formaldehyde and cellulose, and then exposing the impregnated fabric, while the fabric has a moisture content of over 20% by weight where the cellulose fibers are substantially completely swollen, to formaldehyde vapors and curing.

  • Durable press process employing high mositure content fabrics
    Patent number: 3960482
    Abstract: Cellulosic fiber-containing fabrics are made wrinkle resistant by a durable press process which comprises impregnating the fabric with an aqueous solution containing a water soluble acid, acid salt, or mixture thereof, capable of catalyzing the cross-linking reaction between formaldehyde and cellulose, and then exposing the impregnated fabric, while the fabric has a moisture content of above 20% by weight where the cellulose fibers are substantially completely swollen, to formaldehyde vapors and curing.
