It's elongation at break gets increased upto 33% at 100% R.H. Elasticity: Silk is considered to be more plastic than elastic fibre. More work has been carried out in the past to improve the aesthetic and comfort properties of silk fabric. They are exceptionally soft and possess the high heat retention and best moisture-wicking properties of any natural fiber [ 8]. However, unfavorable antibacterial . Silk fibre has an elongation at break of 20-25% under standard conditions. Chambray 5. Despite its immense tensile strength, silk is generally prized for other reasons. Eri silk is also lustrous due to its higher translucency coupled with a uniform cross-sectional area of the fiber. They are physical changes in the fabric that result from applying outside forces on the fabric. Fineness: Silk is a very fine fiber. First, the silk fabric was washed with 60C deionized water to remove impurities before use. Rayon Challis 4. Length - silk is the longest fibre of about 1000 mt ( unbroken filament ) 2. 5. 3rd sem.

Silk, a natural protein fiber, is widely used in the textile industry and biomedical materials for its excellent properties. The difference is that hand-reeled threads produce three grades of silk: two fine grades that are ideal for lightweight fabrics, and a thick grade for heavier material. Lyons velvet It can be made of nylon, polyester, silk or cotton and is found in such diverse items as bridal veils, mosquito netting and ballerina's tutus. The functional properties viz., tensile strength, elongation, resistance to abrasion and pillingsignificantly influence the fabric serviceability. Hammered velvet Considered to be one of the most lustrous forms of velvet, this type of fabric has been firmly pressed or smashed rather than crushed. The moisture absorption results in a temporary 10-25 % strength loss of silk fiber. The following are the physical properties of silk fiber.

Types and Properties of Fabric 1. Copper is measured to conduct heat at 401 Watts per Kelvin and skin tissues measure 0.6 Watts per Kelvin. Silk is more resistant to alkalis and organic solvents, except hydrogen bond-breaking solvents. In this study, 2,4,6-trichloropyrimidine (TLP) was used in the production of anti-wrinkle silk fabrics. The hairs are all medullated (hollow) which decreases their weight by nearly 20% when compared to wool and also increases their insulating properties [ 5]. 100% viscose looks similar to silk it is semitransparent and glossy. Wet strength is 75-85 percent of the dry strength. Silk is a lightweight, breathable fabric, which means it reduces the risk of overheating when you're going about your day. They are-Firstly, Color: The color of silk fiber could be yellow, brown, green, or grey. The physical properties of VTMSi grafted silk were analyzed and compared to fibers grafted with conventional monomers such as methyl methacrylate, methacrylamide, and 2hydroxyethyl methacrylate.

Moisture management properties were tested for the developed samples.100% eri silk knitted denim fabric was found with the excellent accumulative one way transport index % and a very good overall . Thermal Properties Spider silk conducts heat at an average rate of 416 watts per meter Kelvin. 2. Physical properties Crimps: Wool fibre is more or less wavy and has twisted. When compared to synthetic fibres, its tenacity may fall in mid range. Main inner portion (70 80%) is made up of fibroin (true fibre) which is surrounded by a thin covering of . Such as: Breathability. Silk within the gum has rough irregular surface. Physical characteristics are the dynamic physical parameters of fabric. The resulting fabric is dappled and highly reminiscent of the coat of a soft, warm animal. Leather can be highly affected by fire considering the combustion rate, extension and combustion time. It is fluid and has a lovely sheen.

Spider's web made of silk is being used in this process to make textiles. fabrics a re not all made the same or have the same characteristics. When a cross section of the Silk thread is observed under microscope, it is roughly in the figure of 8. Manufactured in various weights, from very fine to coarse, it comes in widths . Tulle is a machine-made fabric netting. Of course, there are more properties of silk fibre than its strength. This textile was just recently surpassed in strength by a lab-engineered biomaterial, but it remains the strongest fabric made through natural processes. It has tenacity usually of 30.9-44.1 cN per tex (3.5-5.0 gram per denier). PMID 17338562. It begins to yellow at high temperatures and disintegrates above 165C.

Silk fibre could also be stretched from 1/7 to 1/5 its original length before breaking. The main countries that produce silk today are China, Japan, Vietnam, Korea, Thailand, India, Uzbekistan, Brazil and Romania. Color - gray, brown, yellow Shrinkage - Silk shrinkage percentage is lower than wool. 2.1 Testing Samples. Golden Chartreuse Hand Dyed Silk Velvet Fabric 4. The application range of silk and its products is very broad. Table 1. However, the surface morphology of silk fiber was very smooth and fine, and the tensile strength was not significantly affected regardless of the graft copolymerization with phosmer M and CL. Jacquard patterns are very stable, strong and durable compared to prints. Spun silk knitted fabrics show lower hysteresis of bending moment than . The amino acidic pattern of sulfated silk remained essentially unchanged for short reaction times (< or =2 h). Properties of Silk: Silk threads are very fine, soft and light in weight. They are very thin but strong having high elastic property. The ends of the fibres from 2-15 cocoons are picked up and woven into a . Silk is a highly lustrous fiber. Satin 10. Length: Silk fiber length varies from 400 to 700 meters. Silk fabrics were treated with chlorosulphonic acid in pyridine for different times. Physical properties of silk fibre: 1. The cocoons are then graded, placed in hot water and beaten to facilitate removal of the outer layer of fibre, which is only of secondary value, and to soften the silk glue. Satin Georgette - a heavier type of georgette constructed in a satin weave. The amount of sulfur bound to silk increased during the first 2 h of reaction and then reached a plateau. Flexibility or pliability. Only a concentrated acid or alkali solution can damage the material. 2.
