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.

This study establishes an eco-friendly anti-wrinkle treating process for cotton fabric. Sodium hydroxide-liquid ammonia pretreatment followed by 6% (w/w) PU100 adding citric acid pad-cure-dry finishing. In this process, citric acid (CA) was used as the fundamental crosslinking agent during finishing because it is a non-formaldehyde based, cost-effective and well wrinkle resistance agent. Environmental-friendly waterborne polyurethane (WPU) was used as an additive to add to the CA finishing solution. Six commercial WPUs were systematically investigated. Fabric properties like wrinkle resistance, tensile strength retention, whiteness, durable press, softness, and wettability were well investigated. Fourier transform infrared spectra and X-ray diffraction spectra were also measured and discussed before and after adding waterborne polyurethane. Tentative mechanism of the interaction among the WPU, CA, and modified cotton fabrics is provided. The effect of cotton fabric pretreatment on fabric performance was also investigated. After the eco-process’s treatment, the fabric wrinkle resistant angle was upgraded to 271 ± 7°, tensile strength retention was maintained at 66.77% ± 3.50% and CIE whiteness was elevated to 52.13 ± 3.21, which are much better than the traditional CA anti-wrinkle finishing based on mercerized cotton fabrics. This study provides useful information for textile researchers and engineers.

Resin Treatment

Cotton textiles received from loomshed undergo various chemical processes before finishing. These processes play an important role in determining the end properties of the unfinished fabric. The effect of processing on tensile strength and fluidity is well known. However, progressive changes in crease recovery, tear strength, and abrasion resistance have not been investigated systematically. Fabric with identical constructions but processed under different conditions often differ considerably prior to resin finishing. In this paper causes for differences in initial crease recovery are discussed. It has been observed that any residual wax present on the fabric after scouring affects the initial crease recovery significantly. Scouring under mild conditions helps to retain a high initial crease recovery. In comparison with thoroughly scoured fabrics, mildly scoured fabrics require less resin to obtain a given crease-recovery angle. The resultant losses in strength after resin treatment are also less.

The main drawback with microorganism's development on fabrics is associated with the maintenance of hygiene and fabric deterioration. In this present investigation a trial has been made to produce an attractive and vibrant textile with eco-friendly antimicrobial dyeing by marigold, a natural resource. Tagetes erecta universally recognized as Marigold is a remarkable source of carotenoids and lutein, grown as a lawn plant. Now a day, lutein is exploding into an indubitably predominant active fitting, employed as an element of the Drugs, Nutrients and Textile Industry. The prospective application of marigold as a characteristic of antimicrobial activity has not been accustomed fully. It is due to the lack of knowledge about its ability and resemblance in material manner. In this work, we have concentrated on the analysis, which was led to deliberate the use of distillate isolate of marigold as an antimicrobial. The antimicrobial competence of the extract was evaluated by coloring on cotton textiles. Testing of the dye ability, its wash quickness and light fastness was done. Educations have validated that antimicrobial coatings have not affected by laundering and shown enhanced colouring effect comprising of fastness to washing, perspiration and rubbing than conservatively dyed textiles. It revealed that the essence of Marigold flower is habitually employed for cotton fabrics as an antimicrobial finish. The samples show very encouraging ends up in terms of antimicrobial resistivity.

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.

To minimize the serious defects of durable press finishing of cellulosic textiles with respect to the great loss in strength properties, new pioneering strengthening approach of cotton fabric based on our previously prepared starch nanoparticles of size around 80–100 nm was used. For this purpose, cotton fabrics were treated with different concentrations of starch nanoparticles via coating technique using pad-dry-cure method, at which the starch nanoparticles are attached to the fabrics with the use of a padder adjusted to appropriate pressure and speed, followed by drying and curing. Fabric stiffness, surface roughness, tensile strength, elongation at break, abrasion resistance, wrinkle recovery angles, add-on %, and degree of whiteness as well as durability of treated fabrics were fully explored. SEM was used for detecting the change in surface morphology of reinforced coated fabric. The results obtained reflect the following findings: (a) all fabric performance like tensile strength, stiffness, wrinkle recovery angle, abrasion resistance and add on % were improved for coated fabrics with starch nanoparticles in comparison with untreated fabric, except that of surface roughness; (b) SEM confirmed the change in surface morphology of cotton fabric after reinforcement treatment using starch nanoparticles; (c) the dry wrinkle recovery angle and tensile strength of cotton fabrics treated in presence of 30 g/l starch nanoparticles are slightly decreased after 10 washing cycles as compared with untreated fabric; and (d) starch nanoparticles introduce an advance in textile finishing with respect to the above-mention fabric performance except that of surface roughness.

In this paper, poly (vinylalcohol glycidyl ether) (PVAGE) was synthesized as a novel reactive stiffening agent to improve the stiffness of cotton fabric. Cotton fabric could be grafted with PVAGE under high temperature and the grafting rate would increase with the increase of PVAGE concentration. The cotton fabric grafted with PVAGE has excellent washing durability. The wearability of cotton fabric grafted with PVAGE was also studied. As the increase of grafting rate, the flexural stiffness increased dramaticly; tensile strength increased a little; cockle elastic decreased slightly; and air permeability and whiteness also decreased but were still in acceptable range.
