Effect of enzyme treatment and dyeing on the mechanical properties of linen

In this paper, different concentrations of cellulase enzyme were used for treating linen fabrics. The pretreated linen fabrics were dyed using a bifunctional reactive dye at various concentrations. The effect of enzyme treatment, together with the dyeing process on the low‐stress mechanical properties of the linen fabric, was then investigated. The low‐stress mechanical properties were assessed quantitatively, including the tensile, shearing, bending, compression and surface properties of the enzyme‐treated and dyed linen fabrics. The results revealed that the enzyme treatment with subsequent dyeing could alter these properties to a greater extent, depending predominantly on the concentration of enzyme used.     

A novel technique to minimise energy and pollution in the dyeing of linen fabric

Garments made from linen fabrics have a natural feel and drape. Most commercially available direct and reactive dyes have only a moderate affinity for this cellulosic fibre, although this lack of affinity can be overcome by the use of electrolytes. As a result, high volumes of wastewater containing large amounts of chemicals are discharged from the typical cellulosic material dyehouse. The ‘no‐salt dyeing’ of linen fabric with reactive and direct dyes was achieved by treating linen fabrics with chitosan in a microwave oven. After using the novel dye method, no observed enhancement of either wash or light fastness properties was seen. Dyebath reuse for both reactive and direct dyes was carried out in order to reduce the environmental impact of the dyes. This dyeing method was then applied to dyeing linen fabrics, with each of the items of clothing subjected to layout and cutting according to the design’s patterns; the dyeing results are discussed in this paper.

Combination of Ozonation and Hydrogen Peroxide Bleaching for Linen Fabrics: Optimization of the Process Using Experimental Design Technique

It is well known that ozone can be used as a bleaching agent for cellulosic textile materials. In the context of this study, investigations were undertaken to optimize bleaching of linen fabrics using Box-Behnken Experimental Design. The bleaching process involved two distinct steps where linen fabrics were ozonated under different treatment times then the latter in a subsequent step were subjected to hydrogen peroxide bleaching under a variety of conditions. As a result of study, three optimum recipes were achieved and pretreatment with ozone for 15 min before peroxide bleaching supplies time and chemical savings.     

Effects of enzymatic treatments on surface morphology and chemical structure of linen fabrics

In previous studies; effects of enzymatic treatments on linen fabrics have been mostly investigated in terms of wettability, sorption properties, whiteness-yellowness index, and K/S values after dyeing. However, surface chemistry and topography of enzyme-treated linen fabrics have not been reported enough. The aim of this work was to examine the effect of pectinase treatments on surface structure and chemical properties of greige linen fabrics by using instrumental techniques. After enzymatic treatment, adequate removal of noncellulosic impurities from the fiber surface has been proved by AFM images and O₁/C₁ ratio of the treated surface. Water drop test measurement and absorbance spectrographs of FTIR analysis have supported the results. It was observed that achievement in bioscouring is familiar to conventional alkaline scouring. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012     

Yellow pigment of Metarhizium anisopliae and its application to the dyeing of fabrics

Microbial dyes have received substantial attention because of their natural environmental protection, simple access, and reduced regional and seasonal restriction. In this work, a microbial dye, the yellow pigment produced by Metarhizium anisopliae, was first studied then applied. The strain produced by the culture was identified, and the conditions for producing yellow pigment were optimised. Further, the stability of M. anisopliae yellow pigment was examined, and the pigment was applied to the dyeing of silk and wool fabrics. The results showed that the homology of the strain with M. anisopliae was 99.98%. In liquid fermentation culture, the optimal carbon source was glucose, and the dosage was 30 g/l. The maximum pigment yield can be obtained by culturing with 4% v/v of inoculation quantity at pH 7 and 30 °C. In addition, the effects of pH, temperature and metal ions on the yellow pigment of M. anisopliae were significant. The optimum dyeing process conditions were dyeing temperatures of 80 °C for silk and 90 °C for wool, with a dyeing time of 60 min. This research developed a novel microbial dye and studied its application for the dyeing of protein fibres.

Anisotropy of Wrinkling of Polyester, Polyester@mdash;Linen, and Linen Fabrics

The anisotropy of wrinkling of polyester, polyester—linen, and linen fabrics in standard conditions and in a maximally humid environment was investigated. It was shown that wrinkling of polyester fabric is close to isotropic, whilie polyester—linen and linen fabric exhibits anisotropy to a greater degree the higher the linen content is. An incrasei n the humidity increases wrinkling of the fabrics in all directions, the difference in comparison to the standard state is insignificant for polyester fabric, but is very pronounced for linen, and the blended fabrics fall in the middle.
