    Abstract: Ultraviolet (UV)-protective textiles have attracted significant attention because of their wide applicability. However, the anti-UV coatings of such textiles have an adverse effect on their wearing comfort, and other properties related to luster, softness and handle were also ignored. In this study, TiO 2 -coated silk fabric with controllable UV-protection properties was successfully fabricated via atomic layer deposition (ALD). The luster, bending properties, crease recovery, mechanical properties, air permeability and anti-UV properties of the TiO 2 -coated silk fabric were investigated. The results showed that the thickness, whiteness, bendability, tensile strength and anti-UV properties of the silk fabric increased progressively while its air permeability, wet crease recovery angle and dry crease recovery angle decreased with an increase in the thickness of the TiO 2 coating. However, the coating did not have a negative effect on the usability of the fabric. Thus, the proposed ALD method is a promising one for modifying the surfaces of elastic textile materials in order to accord them with UV-protection properties.

    Abstract: This work reported the dark dyeing properties of Dioscorea cirrhosa Lour. tuber extracts with different molecular weights on silk. The study on component analysis indicates that the molecular weight of most condensed tannins and polyphenols in D. cirrhosa L. tuber extracts is higher than 1000. The kinetic study demonstrates that the adsorption processes of D. cirrhosa L. tuber extract components with molecular weights higher than 1000, and components with molecular weights lower than 1000 toward silk fabrics are fitted with the pseudo-second order model, and the survey of adsorption isotherms reveals that multiple interactions occurred between dyes and silk, encompassing hydrogen bonding and van der Waals forces. The dyeing research shows that the dyed silk achieves its darkest color when employing D. cirrhosa L. tuber extract components with molecular weights lower than 1000 with a Fe 2+ mordant concentration of 4 g/L and a pH value of 5. The K/S and L* values of dyed silk are 9.05 and 30.77, respectively. Under this dyeing condition, the complex, Fe element content, and Fe 2+ ratio on the silk dyed with D. cirrhosa L. tuber extract components with molecular weights lower than 1000 surface are higher than those of D. cirrhosa L. tuber extracts and D. cirrhosa L. tuber extract components with molecular weights higher than 1000. The present study indicates that condensed tannins in D. cirrhosa L. tuber extracts are not the sole active compounds involved in the silk dark dyeing process. Polyphenols with molecular weights below 1000 in D. cirrhosa L. tuber extracts are shown to influence significantly and, in some cases, dominate the silk dark dyeing process.

    An alkaline pectate lyase D from Dickeya dadantii DCE-01: clone, expression, characterization, and potential application in ramie bio-degumming

    Abstract: Pectinase plays a crucial role in ramie bio-degumming. A pectate lyase gene ( pel4J4) from the high-efficiency degumming bacteria Dickeya dadantii DCE-01 of bast fibers was cloned and connected to pET28a, and then the recombinant plasmid was successfully transformed into Escherichia coli BL21(DE3). The pectate lyase (Pel4J4) induced was purified by ultrafiltration and Sephadex G-100 gel chromatography. The enzymatic properties of Pel4J4 were studied in detail. pel4J4 (GenBank accession number: KC900167) had a sequence length of 1179 bp, encoding 392 amino acids. The extracellular pectate lyase activity of pET28a- pel-BL was up to 204.4 IU/mL. The optimal temperature and pH of the purified Pel4J4 were 55℃ and 8.5, respectively. The stable temperature and pH of Pel4J4 activity were 45℃ and 8.5–10.0, respectively. The catalytic activity is Ca 2+ dependent and promoted by 1 mmol/L Zn 2+ , Fe 3+ , Ca 2+ , and NH 4 + , but seriously inhibited by Cu 2+ and Pb 2+ . The optimal substrate is citrus pectin with more than 85% esterification. The heat-resistant alkaline Pel4J4 could strongly degrade natural ramie pectin, indicating a promising application prospect in ramie bio-degumming.

    Abstract: To explore high-quality microbial resources with the capability of ramie degumming, we collected soil samples from rotten ramie and straw heaps. After enrichment culture by ramie raw materials, bacterial strains with the potential ramie-degumming function were screened using a pectin-hydrolysis plate. Dominant bacteria were identified by combining colonial morphological characteristics with the molecular biology method, and their ramie-degumming effects were verified through comprehensive biological degumming indices. Results demonstrated that Bacillus aryabhattai, Bacillus thuringiensis, Lysinibacillus fusiformis, and Acidovorax temperans were successfully obtained. The highest pectinase activity, 98.2 U/mg, was found by A. temperans. B. thuringiensis showed the best ramie-degumming effect. The residual gum content, single-fiber linear density, and bundle-breaking strength of the degummed ramie fiber treated with B. thuringiensis were 8.32%, 6.80 dtex, and 7.84 cN/dtex, respectively. The residual gum content of the ramie fiber treated with B. thuringiensis met the textile requirement ( 〈 10%), and the values of all other indicators were also satisfactory. Therefore, B. thuringiensis was an excellent strain for ramie degumming, indicating potential industrial applications.

    Study of thermal-sensitive alginate-Ca 2+ /poly( N -isopropylacrylamide) hydrogels supported by cotton fabric for wound dressing applications

    Abstract: In this study, direct deposition, 1,2,3,4-butanetetracarboxylic acid (BTCA) crosslinking, chelating and ultraviolet (UV) photo-grafting methods were employed to bond alginate-Ca 2+ /poly( N-isopropylacrylamide) (PNIPAAm) interpenetrating network hydrogel onto cotton fabric surface for wound dressing applications. Infrared spectroscopy confirmed the presence of alginate-Ca 2+ /PNIPAAm hydrogels on the cotton fabrics. Scanning electron microscopy was used to investigate surface and cross-section morphologies. Differential scanning calorimetry and three-dimensional video microscopy indicated that fabric-supported hydrogels maintained the thermal-sensitive property with a lower critical solution temperature (LCST) of around 34–35℃. The results of water vapor permeation revealed that the water vapor transmission rate at 37℃ was significantly higher than that at 25℃ for the shrink and collapse of the hydrogels above the LCST. Moreover, the breaking stress of the fabric-supported hydrogels was similar to that of the original cotton fabrics, but much larger than the hydrogels by themselves. The UV photo-grafting provided the strongest peel strength, followed by the BTCA crosslinking, the chelating and the direct deposition method. The cotton fabric-supported alginate-Ca 2+ /PNIPAAm hydrogels were stiffer than the original cotton fabric due to the high glass transition temperature of PNIPAAm (about 140℃). The in vitro drug release experiment confirmed that the cumulative release amount was much higher at around 37℃ (above the LCST) than at 25℃ (below the LCST). This showed that the fabric-supported thermal-sensitive hydrogels had functions of keeping the wound area breathable and comfortable, and provided controlled drug release with good mechanical properties, indicating a great potential and significance for wound dressing applications.
