“…It is having the chemical formulae C15H26N5O6. The sericin, which forms the outer layer, is a form of gum having the chemical formulae C15H23N5O6 [1,2]. Unlike all other natural organic fibers like cotton, flax & wool, silk does not have a cellular structure.…”

Silk is one of the valuable fibers in textile industry. It is used for delicate applications in many areas such as sarees, suitings, curtains and luxurious interiors. To diversify the properties and usages silk is mixed with polyester and lyocell. The fabric is dyed with natural dyes (kum kum, indigo, barberry) as well as synthetic dyes (reactive dye (H), reactive dye (M) and sulphur dye). This mixed fabric is compared with 100% silk for some of the basic properties like absorbency, water retention, wicking, water vapour permeability, air permeability, K/S values, colour fastness and antimicrobial property. The silk mixed fabric gives the appreciable results with the 100% silk fabric.

“…Fabric that was modified with 30% acetic acid and 20% tannic acid was dyed with Reactive Brown 10 and Direct Orange 31. The dye uptake depends on the concentration of dye and electrolyte, and dyeing time and temperature of the dye bath; therefore, an attempt was made to determine the optimum dyeing conditions for making the process more economical (Sheikh, 2006;Chen, 2002 Xanthophylls are responsible for the yellow color of raw silk. UV-light in air causes a xanthoproteic reaction, hence the golden yellow color of raw silk turns to a dull yellow.…”

An improved multivoltine variety of Rajshahi silk fabric is used as material for investigation. This fabric is degummed to remove sericin, as sericin is soluble in hot water and highly responsible for the fading of dyed silk after washing. Rajshahi silk fabric is dyed with Reactive Brown 10 and Direct Orange 31 dyes. The color of the silk fabric becomes even and bright when it is dyed with 2.0% Reactive Brown 10 and 2.5% Direct Orange 31 after 50-60 minutes at 80-100°C. To achieve fast color, the silk fabric is treated with six modifying conditions prior to dyeing and among them, comparatively better modifying conditions are selected on the basis of color fastness upon exposure to sunlight in air and wash fastness in a soap solution. The modified Rajshahi silk fabric with 30% CH3COOH and 20% tannic acid together show better dyeing properties than modifications with other conditions and unmodified silk fabric. Direct Orange 31 shows better colorfastness than Reactive Brown 10 after exposure to sunlight in air and also after washing with a soap solution.

“…The proteins in silk fiber are approximately 75% fibroin and 25% sericin by weight. The sericin strengthens the silk fiber and makes it lack luster; therefore, it must be degummed before dyeing [1][2][3]. Silk fiber is well known for its water absorbency, dyeing affinity, thermal tolerances, insulation properties, and luster.…”

Biopolymers are suitable replacement materials for different chemical processes. In this work, silk yarns were treated with different chitosan concentration and then dyed with mono and bi-functional reactive dyes. The color yield, color difference and color fastness to light and washing of the dyed silk yarns were evaluated. Also, the effects of chitosan concentration, type of the reactive dyes on dye uptake of samples were studied. The bi-functional reactive dye has a high adsorption compared to mono-functional ones. The silk yarn treated with 3% chitosan had higher K/S values, washing and light fastness. The effects of chitosan on the antibacterial properties of silk yarns against two kinds of bacteria: Staphylococcus aureus and Escherichia coli were investigated. The treated silk samples were found to have antibacterial potential due to the antibacterial property of chitosan. Scanning electron microscopy (SEM) photographs reveal the deposition of chitosan on the treated yarns. Washing durability, handle properties, and yellowness of treated and dyed samples were also investigated.
