In the anti-wrinkle finishing of cotton fabrics, the decreased dyeability of the finished fabrics has always been a difficult problem. A new anti-wrinkle finishing mode was developed to solve this problem by changing the finishing sequence of fabric dyeing and anti-wrinkle. In this research, the partial oxidization of raffinose with sodium periodate generated multiple aldehydes, which acted as multifunctional cross-linkers and endowed cotton fabrics with anti-wrinkle and hydrophilic properties. The structural characteristics of oxyRa were analyzed by FTIR and 13C-NMR. Through response surface methodology (RSM), the finishing model of oxyRa was established from the influencing factors of catalyst concentration, pH, curing temperature and time, and the optimized finishing process: the catalyst concentration was 20.12 g/L, pH was 4.32, curing temperature was 150 °C and curing time was 120 s. Under this condition, the predicted wrinkle recovery angle (WRA) of the finished fabric was up to 249.76°, Tensile strength (TS) was 75.62%, Whiteness index (WI) was 70.69. Importantly, comparing the anti-wrinkle and dyeing performance of the fabric with anti-wrinkle and then dyeing and anti-wrinkle after dyeing, the oxyRa-treated fabrics showed better dyeing properties compared with previously reported dimethyldihydroxyethylene urea (DMDHEU), glutaraldehyde (GA), and 1,2,3,4-butanetetracarboxylic acid (BTCA). Analysis of the combined mechanism of different finishing agents and cellulose, demonstrated the reason why oxyRa can be used to change the order of dyeing and anti-wrinkle finishing.

Butanetetracarboxylic Acid

The silica sol was applied onto 1, 2, 3, 4-butanetetracarboxylic acid (BTCA) finished cotton fabrics with the attempt to improve the physical properties especially the tensile strength which had a big loss in the previous anti-crease finishing processing. The parameters including the dosage of the coupling agent, the concentration and pH of the sol and the processing methods were studied in detail. Compared to the sample finished with BTCA, 11.8% of the increase in the crease recovery angle and 18.6% of the enhancement in the tensile strength of the cotton fabric also treated with silica sol in the better selected conditions were obtained. The abrasion resistance was also improved.

The application of a fluorine-containing water and oil repellent to cotton and polyester/cotton fabrics was investigated. The influence of dosage of the water and oil repellent, curing temperature and time, and pH of application on water and oil repellencies was discussed to determine the optimized finishing process. In addition, some physical properties of finished fabrics were tested. The results showed that the two fabrics finished with the fluorine-containing water and oil repellent at a low dosage exhibited good water and oil repellencies, and the inherent quality of the fabrics had not been adversely affected.

The formaldehyde-free crease-proof finishing agent 1,2,3,4,-butanetetracarboxylic acid (BTCA) was used to treat lyocell fabrics. The effects of BTCA concentration and curing temperature on the wrinkle recovery angle (WRA) and tensile breaking strength of lyocell fabrics were discussed. The results showed that with the increase of BTCA concentration and curing temperature, the WRA value of lyocell fabrics increased obviously and the maximum WRA reached 147°, but breaking strength decreased gradually and the minimum strength retention was 68%. The WRA was durable against laundering. The fabric whiteness difference was not obvious and the whiteness retention of all samples exceeded 98%. After further alkali treatment, the WRA of the treated lyocell fabrics decreased and the fracture strength retention recovered to varying degrees (0.45–10.8%). The developed regression equations were found to be in good correlation ( r2 > 92%) with the selected variables (tensile strength, BTCA concentration, curing temperature). Fourier transform infrared spectroscopy analysis confirmed that the tensile strength loss of BTCA-treated lyocell fabrics was caused by cross-linking of cellulose molecules and acid degradation. Tensile strength loss that resulted from ester bonding could be restored after hydrolysis in alkaline solution. The recoverable magnitude of tensile strength was related to the curing temperature. A high temperature not only promoted the cross-linking of cellulose macromolecules, but also accelerated the acid degradation of cellulose.

In order to take the advantage of the specific property of sericin to improve wear property of cotton fabric, cotton fabric was finished with sericin. Sericin was fixed onto the surface of cotton fabric in the presence of poly-carboxylic acids (CA and BTCA) at high temperature using a pad-dry-cure process. The effects of catalyst concentration, pH value, curing temperature and curing time on the finish were investigated. The optimized finishing conditions for cotton fabric were obtained. The weight gain of treated fabric with BTCA as crosslinking agent was higher than CA. The whiteness, breaking strength, moisture regain, permeability to gas and crease recovery properties of treated fabrics were measured. The results showed that wrinkle recovery angle evidently increased, and the wrinkle recover angle of BTCA combined secrin treated fabric was higher than CA. The breaking strength, moisture regain and whiteness of the treated fabric slightly decreased, the permeability to gas of cotton fabrics were not changed.

Wrinkle free finishing is a widely used functional finishing process to produce wrinkle-resistant cotton fabrics at the expense of tearing strength of fabrics. In this research, full factors and orthogonal experiments were carried out to invesitgate the mechnism between the wrinkle recovery and tearing strength of cotton fabrics. Wrinkle recovery angle (WRA) was tested by AATCC Test Method 66–2003. Fabric tearing strength, interwoven resistance, and yarn strength were tested before and after resin treatment by a tensile testing machine. By full factors experiment, it was found that the specimen could achieve its best wrinkle-free performance at 110°C curing temperature, 2.5 minutes curing time, 80% pick-up percentage and 60g/l resin concentration considering fabric tearing strength. It is found out that after resin treatment in optimum condition, it could effectively improve the WRA and at the same time with the minimum lose of tearing strength of fabric.

In printing and resin finishing of cotton fabrics, the curing step is involved twice, firstly for fixation of reactive dye and secondly for the fixation of resin for proper cross-linking. In developing country like Pakistan, where cotton is a major portion of textile exports, the elimination of one fixation stage is economical and advantageous. This study dealt with the simultaneous fixation of wrinkle-free finish (resin) and reactive dye printing for cost effectiveness. The processed route of treatment imparted a maximum dry crease recovery angle of 230° and color strength up to 89.89%. The produced fabrics were characterized using crocking fastness (dry and wet), color strength sum %, color fastness to laundry, crease recovery angle, and wrinkle recovery by appearance method. Response surface optimizer gave good composite desirability value (0.08300) with color strength % of up to 73.73 and dry crease recovery angle up to 218°.

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.

Catalyst Chemical Vapor Deposition

A floating catalyst chemical vapor deposition method was developed for the synthesis of quasi-one-dimensional (1D) boron nitride (BN) nanostructures. By carefully tuning the experimental parameters such as growth temperature, floating catalyst concentration, and boron precursor, high quality 1D BN nanostructures including nanotubes, nanobamboos, and nanowires were selectively produced. The microstructures of the obtained 1D BN nanomaterials were characterized, and it was found that the nanostructures are composed of hexagonal BN phase with (002) planes stacking in different manners. A growth mechanism of the BN nanostructures was proposed based on the analysis of their structural characteristics and growth conditions.
