Abstract
The present invention relates to substrate comprising fabric, the substrate treated with a composition comprising: a) formaldehyde; b) polyethylene glycol having a molecular weight of from about 700 gm/mol to about 2500 gm/mol; and c) an acid catalyst; wherein the treated substrate has at least three enhanced fabric benefits, said benefits selected from the group consisting of: i) durable press; ii) hand feel; iii) anti-abrasion; iv) anti-shrinkage; and v) anti-yellowing. The present invention further relates to a system and a process for providing a substrate having the above described enhanced fabric benefits.
Claims22
A process for providing at least three enhanced benefits to a fabric fiber-comprising substrate, said benefits selected from the group consisting of:
- i) durable press, as compared with untreated fabric fiber-comprising substrate;
- ii) hand feel, as compared with untreated fabric fiber-comprising substrate;
- iii) anti-abrasion, as compared with fabric fiber-comprising substrate treated with formaldehyde and catalyst in the absence of polyethylene glycol;
- iv) anti-shrinking, as compared with untreated fabric fiber-comprising substrate;
- and
- v) anti-yellowing, as compared with at least one of untreated fabric fiber-comprising substrate and fabric fiber-comprising substrate treated with formaldehyde and catalyst in the absence of polyethylene glycol;
- wherein said process comprises the steps of:
- A) treating a fabric fiber-comprising substrate with a composition comprising:
- a) formaldehyde;
- b) polyethylene glycol having a molecular weight of from about 700 gm/mol to about 2500 gm/mol;
- and
- c) an acid catalyst;
- and
- B) curing said composition on the surface of said substrate.
A process for providing at least three enhanced benefits to a fabric fiber-comprising substrate, said benefits selected from the group consisting 0f:
- i) durable press, as compared with untreated fabric fiber-comprising substrate;
- ii) hand feel, as compared with untreated fabric fiber-comprising substrate;
- iii) anti-abrasion, as compared with fabric fiber-comprising substrate treated with formaldehyde and catalyst in the absence of polyethylene and catalyst in the absence of polyethylene glycol;
- iv) anti-shrinking, as compared with untreated fabric fiber comprising substrate;
- and
- v) anti-yellowing, as compared with at least one of untreated fabric fiber-comprising substrate and fabric fiber-comprising substrate treated with formaldehyde and catalyst in the absence fo polyethylene glycol;
- wherein said process comprises the steps of:
- A. treating a fabric fiber-comprising substrate with a composition comprising:
- a) from about 2% to about 12% by weight, of formaldehyde;
- b) from about 1% to about 10by weight, of polyethylene glycol
- c) from about 1% to about 12% by weight, of an acid catalyst;
- and
- B. curing said composition on the surface of said of substrate.
