“…Bacterial degumming is an economically and environmentally friendly method that is commonly used in the degumming of traditional bast fibers. Bacteria or actinomyces that secrete pectinolytic enzyme are able to remove gum substances and produce high quality jute (Das et al, 2012), hemp (Kapoor et al, 2001), ramie (Brühlmann et al, 2000;Cao et al, 1992;Zheng et al, 2001;Shen et al, 2015) and banana fibers (Jacob et al, 2008). The bacterial method conserves more energy and produces less pollution, giving it good application potential.…”

Cotton stalk bark fibers (CSBF) with low lignin content were prepared from combined treatments with bacteria and alkali, processed into blended yarns and knitted fabrics, and dyed with reactive dyes. CSBF previously extracted using alkali and peroxide at atmospheric pressure were coarse (>45 dtex) or contained high lignin content (>11.8%), which limited their industrial applications in textiles. We found that alkali removed lignin more thoroughly at 130℃, especially with the assistance of bacteria pretreatment. Fibers after bacteria and alkali treatments had fineness reduced to 24.0 dtex and lignin content decreased to 3%. CSBF/cotton blended yarns from our CSBF had better evenness and breaking strength than jute/cotton blends. Fabrics from CSBF/cotton blended yarns had higher bursting strength, softer and smoother handle compared to the fabrics of jute/cotton blends. Dye sorption of Reactive Red 120 on CSBF was 15.7% higher than that on cotton. Dyed fabric of CSBF/cotton blends had the same laundering and light colorfastness, but slightly lower staining and wet crocking colorfastness than 100% cotton fabric. Overall, CSBF in our study could be used as a good alternative to traditional bast fibers for highly valuable textile applications. The research results will not only enhance the sustainability of fiber industry but also alleviate the environmental pressure.

“…These data are in accordance with others reported in the literature. 22,37,38 After treatment, the relative content of C 1s decreased from 76.17% (that of O-PET) to 71.29%, while O 1s increased from 21.26% (that of O-PET) to 22.05%, and the relative contents of P 2p and N 1s were 2.42% and 4.24%, respectively. The XPS deconvolution scans for the P 2p spectra of F-PET are shown in Figure 7(b), and the binding energy peaks centered at 133.40 and 134.25 eV correspond to P-O and P=O, 39 indicating that phosphorous compounds, such as P 2 O 5 and phosphate ester, are formed due to the oxidation and pyrolysis process.…”

In this work, a novel anti-flame poly(ethylene terephthalate) (PET) fabric was successfully fabricated by plasma-based technology combined with pad-dry-cure treatment finishing. Low-temperature plasma can graft maleic acid (MA) onto a PET polymer backbone, which can activate the PET fiber and provide the opportunity of reaction with pentaerythritol phosphate urea salt (PEPAS) to achieve an excellent and durable anti-flame ability. Furthermore, the chemical reaction between PET-MA and PEPAS can form a complex and compact net structure that can effectively improve the anti-dripping property of PET. Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscopy analysis showed that MA and PEPAS were successfully introduced onto the surface of the PET fabric, and a compact protective carbon layer was formed during the combustion process due to the synergistic effect of phosphorus and nitrogen. The flame-retardant and anti-dripping properties were evaluated by thermogravimetric analysis, the limiting oxygen index (LOI) and a vertical burning test. The treated samples showed the maximum LOI value of 29.3, possessing excellent thermal stability and self-extinguishing ability and inhibiting melt-dripping ability. Moreover, tensile strength at break of the treated PET fabric was slightly greater than that of the original PET fabric, indicating that this type of treatment had little negative impact on the bulk of the PET fabric. After 20 laundering cycles, the LOI value of the treated sample still remained at 26.8, which indicated durability in the flame-retarding effect.

“…The result indicates that the ratio of the amorphous region in lotus fibres decreases with increase in treatment time. The phenomenon can be explained by the fact that the amorphous region of cellulose in lotus fibres is dissolved during their treatment with hydrogen peroxide and their crystalline structure is rearranged and the crystallinity of cellulose increases as the treatment time is prolonged [ 21 ].…”

An efficient technology for preparing lotus fibres under microwave irradiation was developed. The lotus fibres were characterized by scanning electron microscopy, Fourier transform infrared spectrometry, X-ray diffraction and thermogravimetry. Lotus fibres prepared are a kind of hollow fibres which are composed of a superfine fibre and an external shell. The effect of the treatment time with hydrogen peroxide under microwave irradiation on components, whiteness, moisture regain, removal rate of impurities, fineness, tensile strength and breaking elongation of lotus fibres was investigated. The results show that the cellulose content in lotus fibres increases with increase in treatment time. Whiteness and moisture regain of lotus fibres increase with increase in treatment time with hydrogen peroxide. The removal rate of impurities and the fineness of lotus fibres are improved after they are treated with hydrogen peroxide. Microwave irradiation is supposed to be an efficient method for producing lotus fibres.
