Polyethylenimines, degree of polymerization = 7 and 14, were reacted with urea to form polymeric noncyclic analogues of ethyleneurea that were subsequently treated with formaldehyde to yield N-methylol derivatives. These reagents were applied to cotton fabric both alone and in combination with dimethyloldihydroxyethyleneurea. Al2(OH)5Cl·2H2O was the preferred crosslinking catalyst. Fabrics finished with these crosslinking reagent systems had durable-press properties generally comparable to those of fabrics prepared by conventional techniques but were characterized by significantly higher levels of retained strength and abrasion resistance.

Seven different types of flame-retarding finishes were applied to light-to-medium weight cotton fabric at add-ons appropriate to pass the DOC FF 3–71 test. The finishes studied were based on tetrakis(hydroxymethyl)phosphonium chloride (THPC), neutralized THPC (THPOH), Fyrol 76, and Pyrovatex CP. The specific finishes were: THPOH-NH3, THPOH-urea-trimethylolmelamine, Proban (THPC-urea precondensate)-NH3, THPC-urea-disodium hydrogen phosphate, Fyrol 76, Fyrol 76-N-methylolacrylamide, and Pyrovatex CP-methylolmelamine. Textile performance properties are reported as a function of add-on of each type of finish; strengths and abrasion resistance of the finished fabrics are considered and discussed as a function of resilience. General trends of decreasing strength and abrasion resistance with increasing resilience were observed for these flame-retardant fabrics. Within this trend there is latitude for selection of finishes that will provide superior performance in the individual textile property such as abrasion resistance, breaking strength, and tearing strength.

Durable-press (DP) treatments were applied to cotton sheeting that was flame-retarded (FR) with 7 different types of commercial candidate finishes. The finishes, based on tetrakis(hydroxymethyl)phosphonium chloride (THPC), neutralized THPC (THPOH), Fyrol 76, and Pyrovatex CP were: THPOH-NH2, THPOH-urea-trimethylolmelamine, Proban-NH3, THPC-urea-Na2HPO4, Fyrol 76, Fyrol 76-N-methylolacrylamide, and Pyrovatex CP-methylolmelamine. Dimethyloldihydroxyethyleneurea in conjunction with glycolic acid was employed for the DP treatment of each type of FR cotton at each of three levels of add-on. Textile performance properties of DP-FR cotton fabrics are reported as a function of add-on of each of the FR finishes. The relationships of retained strength and abrasion resistance to developed resilience are discussed. Actual responses of the various types of FR cottons to DP treatments were quite different, but they were generally similar in that they showed decreased increments in DP appearance rating as the amount of FR agent on the fabric increased. Although some of the samples of DP-FR fabrics had DP appearance ratings that fell in an acceptable range (3.5-4.0), none exhibited a particularly attractive combination of resilience with retention of strength and abrasion resistance on this lightweight fabric. It is expected that overall performance would be better on heavier weight fabrics.

In this study, acrylamide-containing crosslinking agents 2,4-diacrylamidebenzenesulfonic acid (AC-DABS1) and 2,5-diacrylamidebenzenesulfonic acid (AC-DABS2) were synthesized and applied to cotton fabric as durable press finishing agents under alkaline conditions. The target products were characterized by high-performance liquid chromatography (HPLC) and proton nuclear magnetic resonance. The stability of the acrylamide group in alkaline solution was investigated by model compound para-acrylamidebenzenesulfonic acid. The efficiency of AC-DABS1 and AC-DABS2 as durable press finishing agents was examined and compared by testing the wrinkle recovery angle (WRA), tearing strength retention (TSR) and washing durability under different conditions using the steaming process. The performance of fabric treated with 1,3,5-triacroylaminohexahydro-s-triazine (FAP) was also investigated and compared with those treated with acrylamide-containing crosslinking agents. The results showed that the anti-crease effects of FAP were better than those of the new synthesized agents. However, the new synthesized agents have the advantage of water solubility and low cost. The fabric treated with new synthesized agents presented satisfactory WRA and TSR, indicating that AC-DABS1 and AC-DABS2 can be utilized as effective alkaline crosslinking agents. In addition, the different performance of the FAP-treated fabric and fabric treated with the new synthesized agents was illustrated by the HPLC method.
