In order to solve the difficulty of starch being insoluble under medium and low temperature, a cationic starch slurry modified with etherification was developed. Raw starch was hydrolyzed by sodium hydroxide to improve the dispersion performance, and then the hydrolyzed starch was endowed with cationic groups by N-2,3-epoxy-propyl trimethyl ammonium chloride to improve the dispersion stability. Through various characterization methods, it was found that the quaternary ammonium cationic starch obtained was dissolved in water at medium and low temperature, and the starch structure was changed under the influence of sodium hydroxide and N-2,3-epoxy-propyl trimethyl ammonium chloride. Furthermore, the mechanical properties and abrasion resistance of cotton yarn treated with cationic starch could be significantly improved. Compared with the original yarn, the breaking strength of the yarn treated with cationic starch was increased by 70.05%, the hairiness index of the yarn was reduced by 87.5%, the abrasion resistance was increased by 500.00%, and the stiffness decreased by 276.47%. In addition, the Zeta potential of modified starch was positive, and the degree of etherification substitution of starch ranged from 0.02 to 0.26. The preparation method of etherified starch obtained has the advantages of environmental protection, low cost, and a simple process, which provides a novel way to construct textile size.

“…Zhu et al reported that acid starch (ATS) and 2-acryloxyethyl trimethyl ammonium chloride (ATAC) initiated grafting copolymerization in the ferrous ion redox system, and found that grafted starch with the best grafting percentage of 7.5% significantly improved the adhesion properties of starch with cotton fiber and polyester fiber [ 15 ]. Zha et al studied the grafting parameters of starch and polyacrylic acid (PAA) under different conditions, using ammonium cerium nitrate as initiator, and observed that the abrasion resistance of the sizing yarns was effectively improved, while maintaining a better desizing effect [ 16 ]. Zhu et al employed a series of maleate starches with different degree of substitution (DS) values prepared by treating maleates with maleic anhydride, and the starch films had better elongation and breaking strengths and greater bending resistance after employing low levels of maleation and sulfosuccinic acidification [ 17 ].…”

Warp sizing is a key process in textile production. However, before the yarn/fabric finishing, such as dyeing, the paste adhering to the warp must be eliminated to ensure optimal dyeing properties and the flexibility of the fabric. Therefore, the sizing will often consume a lot of energy and produce a lot of industrial wastewater, which will cause serious harm to the environment. In this study, we have developed an energy saving and environmentally friendly starch-based slurry by modifying natural starch with acrylamide. The paste has excellent viscosity stability and fiber adhesion, and exhibits excellent performance during warp sizing. In addition, the slurry has good water solubility at 60–70 °C, so it is easy to desize at low temperatures. Because of this, the sizing of the warp can be deslimed directly from the yarn during subsequent washing processes. This work can not only reduce some costs for the textile industry, but also achieve the purpose of energy conservation and emission reduction.

“…In comparison to natural starch composites, the starch composite produced through oxidative esterification exhibited higher structural damage, lower crystallinity, and notable improvements in toughness and tensile strength. Zha et al [31] grafted hydrophilic polyacrylic acid branches onto a starch acetate framework using water as the medium. The study demonstrated that the hydrophilic polyacrylic acid branches effectively reduced the crystallinity of starch acetate, mitigated film brittleness, and enhanced the adhesion of starch acetate to fibers and films.…”

In order to actively promote green production and address these concerns, there is an urgent need for new packaging materials to replace traditional plastic products. Starch−based packaging materials, composed of starch, fiber, and plasticizers, offer a degradable and environmentally friendly alternative. However, there are challenges related to the high crystallinity and poor compatibility between thermoplastic starch and fibers, resulting in decreased mechanical properties. To address these challenges, a novel approach combining plasticizer optimization and response surface method (RSM) optimization has been proposed to enhance the mechanical properties of starch−based packaging materials. This method leverages the advantages of composite plasticizers and process parameters. Scanning electron microscopy and X-ray crystallography results demonstrate that the composite plasticizer effectively disrupts the hydrogen bonding and granule morphology of starch, leading to a significant reduction in crystallinity. Fourier transform infrared spectroscopy results show that an addition of glycerol and D−fructose to the starch can form new hydrogen bonds between them, resulting in an enhanced plasticizing effect. The optimal process parameters are determined using the RSM, resulting in a forming temperature of 198 °C, a forming time of 5.4 min, and an AC content of 0.84 g. Compared with the non−optimized values, the tensile strength increases by 12.2% and the rebound rate increases by 8.1%.
