Study On Dyeing Milk Protein Fabric Or Soybean Protein Fabric With PSPC

Purple sweet potato clour is extracted from purple sweet potato.The advantange of PSPC are non-toxicity,harmlessness,non-pollution and better self-stability.It has been used in food,drug and cosmetic.Now it was used in dying of natural fabric.The fabric dyed with natural paint is natural and simple,environmental and safe,and also healthy to people.The protein fiber with powerful, breathable chill-out, feeling soft, shiny bright, and has natural anti-mildew, decay, antibacterial,which are well received by consumers. Milk protein fiber fabrics and soybean protein fiber fabrics using natural plant dyes, which can greatly enhance the added value of bamboo fiber fabrics’ products, satisfy people’s pursuit of clothing appearance, comfort, safety, health requirements.This paper describes the regeneration of natural plant dyes and protein research progress and status of the fabric, through infrared spectroscopy, scanning electron microscopy, spectrophotometric analysis of the Purple Sweet Potato Color structure and performance, and the development trend of the market outlook, and milk fiber and soybean protein fiber morphology and composition analysis of composition, summarizes the regenerated protein fiber. Determined in accordance with their respective characteristics of red pigment from purple sweet potato in milk protein fabric dyeing, fabric dyeing process soybean protein-direct staining, pre-media, mordant dyeing, mordant dyeing, after the media, with loess, aluminum, ferrous salt and mordant.In this paper, orthogonal experiments, range analysis and single factor analysis, the fabric of milk, soybean protein fabric of the direct dyeing of optimum conditions, Purple Sweet Potato Color fabric dyeing regenerated protein has good dyeing properties, but the soap fastness is poor. Through the loess pre-mordant, aluminum pre-mordant, ferrous salt pre-mordant and loess after the mordant, aluminum after mordant, ferrous salt mordant dye staining of milk fabric color characteristic value, dye, color fastness, color contrast, mordant can significantly improve the washing fastness of fabric and dye uptake, dye the milk of loess during pre-mordant dyeing fabric, aluminum pre-mordant dyeing the media better, iron mordant of the latter, reflecting its hyperchromic effect, the dyeing rate is high, but the effects of unstable and dyeing dark colors. Soybean protein fabric through three kinds of mordant pre-mordant dyeing and post-mordant comparison of the effects, mordant can significantly improve the fabric soaping fastness and dyeing rate, pre-mordant dyeing the color than the post-mordant dyeing of vivid colors, loess pre-mordant and aluminum color close to the pre-mordant dyeing, but the pre-mordant loess reddish color, brightness large loess matchmaker more green dye, comprehensive consideration of all factors, the soybean protein fabric dyeing, loess pre-mordant best.This paper also Purple Sweet Potato Color of milk fiber, soybean protein fiber analysis of the mechanism of dyeing, the dyeing rate curve and draw the adsorption isotherm by measuring the milk fiber dyeing thermodynamics and dynamics (diffusion coefficient, half dyeing time, dyeing rate constant) data, elaborated milk fiber and soybean protein fiber dyeing mechanism and to analyze the adsorption isotherm type, the results show that the purple sweet potato color in the milk fiber adsorption is Nernst distribution type adsorption, soy protein Fiber tends to Langmuir-type, research on Purple Sweet Potato Color of product development and has some practical applications guide.
