Antibacterial properties of linen fabric Study

Qualitatively and quantitatively the antibacterial properties of flax fibers were authentic assessment, and use scientific methods to the common determination of the flax fiber is the role of bacteria and fungi in the experiments on ten 2 Experimental 2.1 Materials 36Nmx36Nm bleached pure linen fabric, fabric for the warp density 5l root / London, weft density 47 / British time; 36NmX36Nm pure color rain hemp cloth, fabric above; compared with a cotton cloth 21 × 21, fabric Ibid. 2.2 Methods 2.2.1 contact method will cut the same size in all kinds of small specimens (34mm × 20mm),[link widoczny dla zalogowanych], dropping each specimen bacilli 0.1mL, after a certain time, remove the two , release oscillations in normal saline 10mL elution, lotion for the standard plate count, calculated survival of bacteria at different times. 2.2.2 leaching solution method for each sample taken 20g, were placed in 20mL saline soak for 24 hours, take the leaching solution into broth 4.5mL 0.5mL, made after dilution of the standard plate count, and the natural decline of bacterial suspension Received date :2002-06-05 Author: History of strengthening (1954 a), Chief Engineer, Institute of Textile Industry of Heilongjiang Province, Research Fellow. History of enhancement, 1O: Antibacterial properties of linen Study 3 rate as the control. 2.2.3 Each sample smoked law to take 20g, 250mL of the jar placed in the middle leaving gaps. Dropping bacilli in the (5 × 15) cm2 filter paper, suspended in the central bottle, to be dry. After some time out, shock-eluting, lotions do the standard plate count, an empty jar built the same mushroom as controls. 2.3 Experimental results 2.3.1 2.3.2 contact method results leaching solution method results in the leaching solution at different times of bacteria mortality (%) bacterial species sample types - 3h6h12h (on the next page 8) 5 Conclusion (1) the implementation of high-pressure sizing process, we must choose the high concentration and low viscosity of the slurry as a prerequisite. (2) using two high and one low-sizing process, can enhance the penetration of the yarn to ensure the coating, the sizing structure, the quality of the sizing significant results. (3) using two high and one low technology can improve the yarn strength, 2.3.3 smoked smoked method results at different times after E. coli bacteria samples on the chip type - the starting letter of bleaching linen cloth rain Asahara l2II48h colored cloth cotton cloth bacilli were 2.0X100 ∞ 7.9X1 ∞ 08.3X100D5.9 × leo2.0Xleo2.

In pure hemp fabric, hemp rain Antimicrobial effect of color than cloth bleaching linen cloth. observe the smoked method results can initially determine, linen fabric odor no significant role in killing E. coli. antimicrobial properties of flax fiber in the world causes a problem for the industry. flax whole plant from the plant to be processed into textile products after at least three biological and chemical processing,[link widoczny dla zalogowanych], that is, the biological flax retting processing, chemical retting flax roving linen bleaching and scouring and bleaching. especially the bleaching of linen and linen roving the scouring and bleaching process conditions used in high temperature, strong alkali and high concentrations of oxidants. Thus,[link widoczny dla zalogowanych], the general theory, even if the flax hemp contains some anti-bacterial ingredients, then processed through the enhanced learning will inevitably destroy its anti-bacterial ingredients leaving the final loss of antimicrobial linen textiles. Therefore, the final crack antibacterial mechanism of linen, still have to conduct in-depth research and analysis. and linen fabric antibacterial effect of experimental data obtained, the development of anti-bacterial health-care textiles and linen development of domestic textiles are still of great significance. to increase wear and reduce the hairiness, can improve the open definition, reduce breakage, reduce and twist, twist and other defects stick. (4) using two high and one low-sizing process, sizing sub-cutter smooth cutter is continuously in the dry sub-head, sizing litter less smooth yarn, weaving shaft, good appearance,[link widoczny dla zalogowanych], weaving openings clear, no adhesion phenomenon, to ensure a good axial ratio sizing to improve the weaving efficiency. (5) using two high and one low-sizing process, in linen / cotton can be completely replace the PVA, 30% can reduce the cost of sizing, desizing easy to ensure,[link widoczny dla zalogowanych], to the real nature of green products.
