“…The polymer viscosity became larger and larger, indicating that the molecular weight of the polymer also increased. The chelating ability was improved by the formation of more polymers 32 . When the temperature continued to rise to 75 °C, the reactants was too viscous to obtain the final product.…”

Using potassium peroxodisulfate as an initiator and acrylic acid as a monomer, an acrylic acid oligomer was synthesized and then compounded with magnesium salt to form a non-silicone oxygen bleaching stabilizer. By investigating the effects of reaction temperature, reaction time, initiator concentration, monomer concentration, and magnesium salt dosage on product performance, the effect of stabilizers on linen yarn bleaching was analyzed. The synthetic conditions of oxygen bleaching stabilizer were determined by orthogonal test method, namely, acrylic acid monomer concentration 25%, initiator dosage 5%, oligomeric acrylic acid and magnesium salt compound ratio 5:1, reaction temperature 65 °C, reaction time 4 h. At this time, the chelated iron value of the product was as high as 239.314 mg/g, and the chelated calcium value also reached 145.000 mg/g. The dosage of the synthesized stabilizer were determined to be 4 g/L through indicators such as the decomposition rate of hydrogen peroxide and whiteness. The results showed that the environmentally friendly non-silicone oxygen bleaching stabilizer not only had a good ability to inhibit the decomposition of hydrogen peroxide, but also provided bleached linen yarn with a superior degree of whiteness and less metal ion residue, which can effectively solve the “silicon scale” problem and improve the quality of the pre-treatmented products.

“…This is consistent with the results of the only CA treated samples based on our previous research. 5 Though a low adding dosage of WPU can slightly increase the tensile strength of the treated sample, most of the specimens show a decrease in tensile strength as the anti-wrinkle properties are greatly increased. Furthermore, the only 6% PU100 treated cotton fabric also experienced tensile strength loss.…”

“…These wrinkles and shrinkages seriously affect the cotton fabric appearance. 4,5 Crosslinking of the cellulose hydroxyl groups could effectively improve the anti-wrinkle property of the cotton fabrics. 6 Dimethylol dihydroxyethyleneurea (DMDHEU) and other N-methylol compounds are currently the dominant crosslinking agents used for anti-wrinkle finishing due to its excellent performance and cost-effectiveness.…”

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.

“…Some studies have found that the low temperature bleaching system can be carried out under near neutral pH conditions (Long et al 2013;Xu et al 2013). These bleaching activators mainly include tetraacetylethylenediamine (TAED) (Hebeish et al 2009;Long et al 2013;Shao et al 2010;Xu et al 2013), N-[4-(triethylammoniomethyl)-benzoyl]-caprolactam chloride (TBCC) and other lactam-based cationic bleach activators (Chen et al 2016;Lee et al 2010;Lim et al 2006;Luo et al 2019;Xu et al 2015). Other activators like sodium nonanoyl oxybenzene sulphonate (NOBS) (Cai et al 2001), amino nitriles as well as the derivatives of the cyanamide (Neal JM 1998), thiourea (Abdel-Halim andAl-Deyab 2013), pentaacetyl glucose (PAG) (Liu et al 2017) and tetraacetylhydrazine (TH) (Liu et al 2018) are also effective low-temperature bleaching activators.…”

Near-neutral bleaching of cotton fabrics at low temperature is of great importance for saving energy and ecological friendliness in textile industry. In this work, glycerol triacetate (GT) was investigated as an activator of hydrogen peroxide (H 2 O 2 ) for low temperature bleaching of cotton knitted fabrics, and satisfactory whiteness was obtained. The bleaching properties of H 2 O 2 /GT system for cotton was assessed by the CIE whiteness index, H 2 O 2 decomposition rate, concentration of generated peracetic acid (PAA) and bursting strength. Possible factors affecting the performance of H 2 O 2 /GT bleaching system were discussed in detail. Adding only 10 mmol/L GT to the hydrogen peroxide solution (60 mmol/L) to bleach cotton knitted fabrics at 60 ℃ for 60 min, the WI was signi cantly increased from 52.09 to 68.92.By using benzenepentacarboxylic acid as a uorescent probe for hydroxyl radical (HO•) detection, it was found that GT could clearly promote HO• generation and the concentration of HO• closely related to the WI of cotton fabric. Furthermore, the bleaching mechanism of H 2 O 2 /GT system to cotton was proposed by exploring the relationship between WI and HO• concentration. As a bleach activator, GT has more economical bene ts and better solubility in water than that of TAED. The H 2 O 2 /GT system may provide a cost-effective and environmentally friendly approach as alternative to conventional alkaline hightemperature bleaching of cotton.
