Crosslinking Agents

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.

Polyaldehyde trehalose (OTr) was prepared and applied to cotton fabric as an anti-crease finishing agent under Lewis acid conditions. OTr contains reactive groups (aldehyde groups) and hydrophilic groups (hydroxyl groups). After the aldehyde groups crosslink with the hydroxyl groups of the fibers, the hydroxyl groups of the OTr improve the hydrophilicity of the finished fabric. The target product was characterized by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance. The optimum process conditions for anti-crease finishing were studied. The optimal anti-crease finishing process for OTr was 10.0%, a MgCl2 concentration of 2.0%, a pH of 3, and curing for 3 min at 150℃. The efficiency of the OTr-treated cotton fabrics was examined, and the anti-crease property, whiteness, tensile strength, hydrophilicity, and staining property of the OTr and conventional anti-crease finishing reagents were compared. The anti-crease property, whiteness, and tensile strength of the OTr-treated fabric improved significantly, but were lower than those of the butane tetracarboxylic acid and glutaraldehyde. Fabric that was treated with the new prepared agent presented a satisfactory hydrophilicity, which indicates that OTr can be used as an effective hydrophilic crosslinking agent.

Durable Press Finishing

Polycarboxylic acids appear to be the most promising nonformaldehyde durable press finishing agents to replace the traditional N-methylol reagents, 1,2,3,4-Butanetetracarboxylic acid (btca) is the most effective crosslinking agent among the acids investigated, but its exceedingly high cost has prevented its use in the textile industry on a commercial scale. In this research, we evaluate the effectiveness of two polymers of maleic acid, i.e., the homopolymer (pma) and the terpolymer (tpma), along with citric acid (ca) for crosslinking cotton cellulose., pma, tpma, and ca have molecular structures similar to btca, but are more cost effective. We have found that pma and tpma are less effective crosslinking agents for cotton than btca, probably due to the low mobility of the anhydride intermediate formed by pma or tpma to access the cellulosic hydroxyl during the curing process. We have found that the hydroxyl of ca and other α-hydroxylpolycarboxylic acids hinder the esterification of those acids with cellulose. The infrared spectroscopy data indicate that ca esterifies the anhydride intermediates of pma and tpma on cotton fabric under curing conditions. Consequently, ca is transformed from a trifunctional acid to a tetrafunctional one with the formation of an ester linkage with pma or tpma.

Washing Durability

Crosslinking of cellulose is considered a necessary process in creating anti-wrinkling cotton fabrics. In the recent years, the concern of buyers regarding the wrinkle-resistant fabric has increased the demand of easy-care finishes. Formaldehyde based easy care finishes are carcinogenic but still used in the textile industry. Low formaldehyde reagents are being developed and tested to replace formaldehyde based easy care finishes. In this research the low formaldehyde easy care finishes; Fixapret ECO and Alkaknit WFR were investigated for their effect on color fastness to crocking, tear strength, tensile strength and durable press rating. Findings of the research showed that the there was a subsequent decrease in tensile and tear strength as compared to original fabric with the increase in resin concentration on both type of dyes. From the results we can say that higher the resin concentration, better the washing durability. This is due to the fact that resin decreases the chance of fiber chain displacement. The fabric with navy blue dye displayed much better performance and compatibility with non-formaldehyde resins as compared to turquoise blue dye.
