Acid hydrolysis of cellulosic fibres: Comparison of bleached kraft pulp, dissolving pulps and cotton textile cellulose.
The behaviour of different cellulosic fibres during acid hydrolysis has been investigated and the levelling-off degree of polymerisation (LODP) has been determined. The study included a bleached kraft pulp (both never-dried and once-dried) and two dissolving pulps (once-dried). Additionally, cotton cellulose from new cotton sheets and sheets discarded after long-time use was studied. Experiment...
متن کاملAntibacterial Agents in Textile Industry
The spread of HIV and hepatitis viruses by contact of contaminated materials has created increased pressure for protection of personnel with functional clothing; also, all articles of apparel and home textiles are susceptible to problems of hygiene in normal daily use, for example, socks, sport wear and working clothes as well as mattresses, floor coverings, and shoe linings. Textiles for outdo...
متن کاملThe Sorption Behaviour of Cellulose Fibres
Cellulose fibres are the most important materials in textile finishing. Reactivity and adsorption properties of the fibres are critical for the success of the treatment. Of major interest are the properties of fibres swollen in polar liquids. Under this circumstances the less ordered regions determine the fibre properties and therefore the void size and accessible amorphous regions are supposed...
متن کاملA3-Coupling catalyzed by robust Au nanoparticles covalently bonded to HS-functionalized cellulose nanocrystalline films
We decorated HS-functionalized cellulose nanocrystallite (CNC) films with monodisperse Au nanoparticles (AuNPs) to form a novel nanocomposite catalyst AuNPs@HS-CNC. The uniform, fine AuNPs were made by the reduction of HAuCl4 solution with thiol (HS-) group-functionalized CNC films. The AuNPs@HS-CNC nanocomposites were examined by X-ray photoelectron spectroscopy (XPS), TEM, ATR-IR and solid-st...
متن کاملAntibacterial Effect of Carboxymethyl Cellulose Coating Enriched by Zataria Multiflora Essential Oil and Grape Seed Extract
Abstract Background and objectives: The presence of pathogenic bacteria and the factors causing food spoilage are the great challenge for public health. Attention to natural additives instead of chemical preservatives resulted in conducting several studies on plant essential oil and extracts. We aimed at evaluating the antibacterial effect of carboxymethyl cellulose coating enriched by Zataria...
