This report employs a combination of alkali and dipodal silane treatments. Bridged bis (3-trimethoxysilylpropyl) amine (BAS), a dipodal silane, was used instead of regular ones to enhance the hydrophobicity of ramie plain-woven fabrics. Before silane application, alkali treatment conditions’ impact on mechanical properties was optimized using response surface methodology (RSM). The desirability function approach and graphical optimization techniques were employed to find out the optimum condition. The RSM demonstrated that a concentration of 6.11% alkali, a duration of 30 min, and a temperature of 39.10 °C yielded the optimal conditions, resulting in a breaking force of 518.27 N and an elongation of 23.36%. After optimization of parameter, alkali treatment of the fabric was carried out. These alkali-treated fabrics were then bulk-treated with BAS. The Taguchi L9 orthogonal array experimental design was applied to identify a variable that has the highest impact on the hydrophobicity. Furthermore, BAS’s impact on water contact angle (WCA), surface morphology, and thermal properties was investigated. Alkali-treated ramie fabrics absorb water due to hemicellulose and lignin removal. However, BAS treatment resulted in a hydrophobic ramie fabric surface, as the combined alkali and BAS-treated fabrics exhibit a WCA greater than 94°, reaching 113.85°. According to thermo-gravimetric analysis, combined alkali and silane treatment improved the degradation temperature of fabrics to 403.25 °C. This improvement is attributed to the formation of six, rather than three, Si–O bonds on the ramie fabric surface.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 11","pages":"4307 - 4320"},"PeriodicalIF":2.2,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the fiber diameter range of 10–15 μm. To improve the incorporation rate of seaweed powders, the particle size distribution and compatibility of seaweed powders in NMMO were first studied. On comparing the powder size distribution of seaweed particle in different disperse liquid, it was found that seaweed powders are partially soluble in NMMO and weaken the inherent alkaline environment, while the remaining powders swell more significantly with increasing NMMO concentration. Following this protocol, an integrated dispersion process was successfully developed with high seaweed loading in low-concentration NMMO solution. The resultant functionalized seaweed modified lyocell fibers (abbreviated as “SL Fiber”) demonstrated effective loading of seaweed particles, comparable mechanical properties, improved heat resistance and antibacterial properties. Thus, the fibers meet the major requirements for hometextiles, packaging materials, filtration, and other fields. The antibacterial rates of fibers against <i>Escherichia coli</i>, Staphylococcus aureus, and <i>Candida albicans</i> all reached the requirements, inhibiting harmful bacteria growth and preventing mold and odor.

In a single-step exhaust method, the blended fabric is treated with 60% calcium chloride-based desiccant at 60 °C for 1 h. The multidirectional liquid transport behavior of treated fabric through properties such as time for wetting, rate of absorbing moisture, maximum radius of wetted area, speed of spreading the test liquid, moisture transport index, and total moisture management capacity is analyzed. The experimental results exhibit improvement in the moisture management property of the treated fabrics from 0 to 0.75. The wettability of the fabric is also enhanced as the water contact angle has reduced from 108.37° to 66.45° after the treatment. Treated samples transport the test liquid across the fabric much more quickly than untreated samples due to fabric–desiccant interaction through a strong hydrogen bond. This is characterized by an FTIR peak at 2341 cm<sup>−1</sup> which gets reduced after treatment. The impact of desiccant treatment on physical properties such as color strength, fabric thickness and weight was also analyzed. The desiccant treatment shows durability up to five wash cycles equivalent to 25 home laundering cycles, dictating a great prospect of applying this method in the moisture management of cotton–acrylic-blended textiles. Moreover, the presence of randomly deposited desiccant particles on the blended fabric surface confirmed by SEM is achieved in a single step, emphasizing the versatility of this method.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"25 11","pages":"4291 - 4306"},"PeriodicalIF":2.2,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
