Problems solved by technology

For example, among the methods using durable set modifiers, many are carried out under strong acid conditions which can cause the natural fiber to lose up to 50% of its strength
Furthermore, the increased fabric properties may be short-lived, and while this fact is in many cases accompanied by reduced fiber strength, the overall effect is a decrease in overall fabric quality
Additionally, the addition of antistatic or softening agents can alter the softness properties of the fabric, leading to an increased tendency for the fabric to wear prematurely

Embodiment 1

[0207] Methods for providing at least three enhanced properties to fabric-containing substrates are described below. The substrate is Lenzing rayon. Compositions used to treat said substrates include:

[0208] a) 56.37 grams of 37% by weight formaldehyde in water to form 20.86 grams of formaldehyde

[0209] and 35.51 grams of water;

[0210] b) 15.66 grams of 27.3% by weight aluminum chloride / magnesium chloride catalyst

[0211] FREECAT  9 solution, forming 4.28 grams of catalyst and 11.38 grams of water;

[0212] c) 0.31 grams of Tergitol TMN-6;

[0213] d) 15.66 grams of PEG1000 (polyethylene glycol, the average weight-average molecular weight is about 1000

[0214] g / mol);

[0215] e) 2.25 grams of SM2112;

[0216] f) 129.75 grams of deionized water.

[0217] The solution administered included:

[0218] formaldehyde

[0219] The following system of the present invention assumes that 70.25% by weight of the solution is wet absorbed to deliver 5% PE...

Abstract

The present invention relates to substrate comprising fabric, the substrate treated with a composition comprising: a) an aldehyde, said aldehyde a mono-functional aldehyde, a di-functional aldehyde, or mixtures thereof; b) a polyethylene glycol having the formula: R(OCH2CH2)xOR wherein R is hydrogen, C1-C4 alkyl, and mixtures thereof, and the index x has a value of 15 to 45; c) an acid catalyst; and d) optionally, a surface modifying agent; 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 37 U.S.C 119(e) based on U.S. Provisional Application Serial No. 60 / 180,539 filed February 7, 2000 (Attorney Docket No. 7971P). field of invention [0003] The present invention relates to systems for enhancing the properties of substrates including woven and nonwoven fibers. Substrates treated with the system of the present invention have at least three enhanced properties relative to untreated substrates or relative to existing methods. Background of the invention [0004] Of all the different articles, apart from those related to simple machines, those containing fabrics are the most common and have been known since ancient times. These textile-containing articles most commonly take the form of substrates, especially clothing (apparel), furniture surfaces, shoelaces, cloth. Said substrate comprising fabric may be a natural material, such as cotton, wool, etc., or a synthetic ...
