Protein Fiber

Protein fibers are attractive topics in the past decades. Among them, soybean protein fiber, the regenerated protein-base fiber, is very popular due to its luster, smooth surface, breathability, and comfort. In order to blend with wool and reach union dyeing, soybean protein fiber was first bleached due to its yellow appearance. Various bleaching processes were introduced in this paper. Reactive dyes for cellulose and for wool, such as Unisol or Megafix dyes, together with proper dyeing process were selected and compared. The results showed that one-time oxidation bleaching is confirmed as the bleaching process due to its compromise of high whiteness and bursting strength. It is unable to reach union dyeing for soybean protein fiber/wool fiber with Unisol or Megafix dyes respectively while it is feasible to reach union dyeing of soybean protein fiber/wool fiber dyeing with Unisol dyes followed by Megafix dyes.

This study assesses dyeing performance of reactive dyes with monofluorotriazine and modified cvinyl-sulfone bifunctional reactive groups in alkaline/acid denaturalization bath to the soybean fibers. It has been shown that 3~4 of the dyeing pH value, 60 minutes and 70°C of dyeing time and temperature were selected for denatured bath. The denaturalization bath can dramatically improve exhaustion and fixation and significantly decrease the chromaticity of the dyeing effluent. Besides, colorimetric properties, fastness and mechanical strength of the dyed fabrics were evaluated to indicate applicability of this dyeing process of soybean protein fibers.

In order to understand the influence of the blended ratio of the soybean protein fibers to the properties of blended fabrics, five soybean protein fiber/modal blended fabrics are knitted and tested. By the analysis of the results, the relationship between the properties of the blended fabrics and the blended ratio of the soybean protein fibers are obtained. With the increase of the ratio of the soybean protein fibers, the tensile strength and the elongation of the blended fabrics increase and the tearing strength and bursting strength of the fabric decrease. With the increase of the ratio of soybean protein fibers, the softness increases and the bending length, abrasion resistance of the knitted fabrics decrease.

In order to describe the relationship between the elasticity and the strength and the blended ratio of soybean protein fiber/combed cotton blended yarn, the strength and elasticity of different kinds of blended ratio of soybean protein fiber/combed cotton blended yarn was measured. The relationship between the strength and the blended ratio of blended yarn is not in accordance with the simple model. With the increase of the blended ratio of the soybean protein fibers, the strength and the elasticity of the blended yarn increased.

Protein fibers are attractive topics in the past decades. Among them, silk and wool fibers are very popular due to their luster, smooth surface and comfort. In order to reach union dyeing of silk/wool blends, chlorination pretreatment or introduction of low-temperature dyeing auxiliary for wool are selected and compared. The results showed that chlorination pretreated wool/silk dyed with weak acid dyes, can reach union dyeing under 80 oC, possibly under 70 oC. On the other hand, introduction of low-temperature dyeing auxiliary can slightly improve the union dyeing at different temperature ranges according to selection of weak acid dyes.

In order to study the method to determine the blended ratio of the soybean protein fibers, the calculation of the mean and standard deviation of the blended ratio of soybean protein fiber/polyester blended yarn by the statistical theory and density gradient method is discussed in this paper. The method can derive not only the mean but also the standard deviation of the blended ratio of the soybean protein fiber/polyester blended yarn. The control range of blended ratio of roving and ring yarn is (63.63%, 65.32%) and (64.16%,66.17%).The control range of the standard deviation of roving and ring yarn is 2.89% and 3.56%. The blended ratio of the ring yarn by the chemical dissolution is 64.5% at the same time. The error of the two methods is only 1.1%.

Spartium Junceum

In this study, the natural dye was extracted from Spartium junceum L. (SJL) flowers and applied on cellulose (cotton) and protein (wool) fabric. Fabrics were pre-mordant with alum prior to the dyeing process. Considering the global requirements on zero waste and green policy, the dyeing process was intended to be as much as possible environmentally friendly but still effective. Therefore, mordant concentration was optimized due to the reduction of the negative impact. The efficiency of the dyeing process was investigated by examination of fabrics’ color characteristics and colorfastness to washing properties. In this paper, we have proved that the extracted dye from Spartium junceum L. is an acidic dye (mordant dye) which is more applicable for the treatment of wool fabrics. In this paper, it was proved that phytochemicals responsible for coloring are part of the flavonoids group. The UV absorption spectra of extracted dye show 4 bands in the region of λmax 224, 268, 308 and 346 nm which are ascribed to bands characteristic for flavonoids. Wool fabric pre-mordant with 3% alum and dyed shows great chromatic (C*) properties where C* value is in a range from 47.76 for unwashed samples to 47.50 for samples after 5 washing cycles and color hue (h°) is in a range 82.13 for unwashed samples to 81.52 for samples after 5 washing cycles. The best result regarding the colorfastness properties is shown by the wool sample treated with 3% alum after 5 washing cycles (total difference in color (Delta E*) = 0.87). These results confirm that metal (Al) from alum mordant make strong chemical bonds with wool substrate and dye since Delta E* values decrease in comparison to Delta E* values of the cotton samples treated the same way. The results revealed it is possible to reduce the concentration of mordant up to 3% and obtain satisfactory results regarding the colorfastness. Nevertheless, future research will go in the direction of replacing synthetic mordant with a more environmentally friendly one.

The Impact

Wool fiber was firstly pretreated by nano-SiO2/Ag antibacterial agent, and then dyed with an acid dyes at low temperature by ultrasonic dyeing. Many factors had an important influence on the dye ability and the antibacterial behavior during the dyeing process of antibacterial wool fiber. The experimental results indicate that the dye-takeup rates of antibacterial wool fiber were enhanced with the increase of the concentration of nano-SiO2/Ag, the dyeing temperature, the dyeing time and the ultrasonic frequency (less than 60Hz). However, the antibacterial ratios of wool fiber were declined in the impact of these factors other than the concentration of antibacterial agent.
