However, the low utilization of chemical reagents and poor production efficiency in the cationization process trigger its multiple environmental pollution in the late-stage dyeing industry. Herein, we develop an efficient, clean and low-cost cationic modification method of cotton fabrics, which could greatly reduce both the chemical usage (3-chloro-2-hydroxypropyltrimethyl ammonium chloride ((CHPTAC) and NaOH) and overall treatment costs compared to the conventional approaches. The modification is designed to achieve an efficient and competitive cationization effect through a facile one-bath pad-bake process. Under the pressure of the rolls, CHPTAC with low molecular weight diffuses rapidly and flexibly, ensuring even distribution within the fiber for comprehensive cationization. Notably, the as-prepared cationic cotton exhibits higher color depth with only half the dye utilization in traditional methods. Implementing the proposed one-bath pad-bake cationic process results in reductions of 8.3%, 40% and 50% in CHPTAC, NaOH and water usage, respectively, while a 96% decrease in processing time compared to conventional exhaust method. This novel and efficient approach holds great promise to be widely used in practical application of cationic modification in textile and coloration industry.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 2","pages":"1325 - 1338"},"PeriodicalIF":4.9,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, hexadecyl trimethoxysilane (HDTMS) and butane tetracarboxylic acid (BTCA) are applied to reduce fiber surface energy. This combined approach results in CFs with outstanding superhydrophobic properties, boasting a water contact angle of up to 155°, surpassing nanoparticle-based surfaces. Furthermore, these fabrics exhibit remarkable mechanical and chemical stability, along with enduring washing durability. Notably, they demonstrate effective self-cleaning abilities in the presence of liquid contaminants and excellent oil/water separation performance with a high separation efficiency.

Thus, it is a challenge for professionals to address such issues amicably to achieve a net zero footprint on the environment. Ramie degumming and its effective management is one such challenge that needs appropriate and effective management of discharged chemicals. The present article emphasises a method for processing ramie fibre, employing modern techniques that replace conventional chemical treatments. Thus, the alternative biocatalyst i.e., the enzyme concoction extracted from a novel brown rot fungus <i>Formitopsis cf melia</i> has been used that not only efficiently degum the fibre in a shorter span of time but also in a cost-effective manner. The process provided a degumming time of 6 h with residual gum content of 5.39 ± 0.12%, yield of 94.59 ± 0.95% and whiteness index of 68.3. Further, a two-parameter Weibull distribution has been performed to obtain increased Weibull modulus of the Steam Explosion-Enzymatic Treatment (STEX-ET) processed fibre (4.4857) at an R<sup>2</sup> value of 94.60% and tenacity of 9.84 ± 2.30 cN/dtex compared to the chemically treated process demonstrating better efficiency, reliability and feasibility with improved mechanical properties. The chemical oxygen demand of the degummed solution in the STEX-ET process was 2296.58 ± 68.88 mg/L, emphasizing the environment-friendly aspects of this enzymatic treatment.
