Also, moisture affects the strength of . Physical properties of silk fibre: 1. It can be seen that silk has good moisture absorption properties. 2. Natural fibers have good hygienic properties due to their good moisture absorption properties. Yarn: diameter, twist, weight or size, count, fiber content for mixed yarns, ply. Whatever, silk can be treated with a 16-18% solution of sodium hydroxide at low temperature to produce crepe effects in mixed fabric containing cotton. The silk fiber is produced as filament in spinning glands. Try out the filters to find exactly what is needed and start shopping now! The action of reducing agents on silk fiber is still a little bit obscure. The flat surfaces of the fibrils reflect light at many angles, giving silk a natural sheen Resilience: Silk retains the form and resists wrinkling very well. Absorbency: the great absorbtive property of silk additionally contributes to its impact in hotter atmosphere. Firstly, Color: The color of silk fiber could be yellow, brown, green, or grey. Under the experimental conditions of 20 C and a relative humidity of 65%, the moisture absorption rates of several fibers are: wool 16%, silk 11%, cotton 8%, viscose 13%, nylon 4%, and polyester 0.4%. Affinity for dyes : Silk has superb affinity for acid dyes however lightweight fastness is unacceptable. Modal fabric is cheaper than silk, but it's slightly more expensive than viscose rayon and roughly equal to the cost of cotton and lyocell. 5.

Silk is a protein fiber of insect origin, being produced as a fine filament of long length from the body fluid of silkworm. a lot of over smoothness of the silk filament yarn reduces the matter of wear and tear from abrasion. Silk fabric possess good abrasion resistance as well as resistance to pilling. Water weakens the fibres, though, so treat your silk carefully when youre washing it. length of individual fiber cells are 6-65 mm ( inch - 2 inch) and mean diameter of about 0.02mm (1/1200 inch). The properties of silk allow these devices to be biologically activated offering new opportunities for sensing and biophotonic components. Silk tears, discolors and stains easily, often requires dry cleaning and is an animal product shunned by most vegans. Velvet made completely of silk is hard to get your hands-on, so youre more likely to find it mixed with rayon.

Thirdly, Tensile Strength: Silk is a strong fiber and it has a tenacity of 3.5 - 5 gm/den. Silk is more sensitive light than any other natural fiber. The strength is greater than cotton fiber. Silk loses strength on wetting. Woven fabrics: weave type, warp and filling yarn count per linear inch

, Knitted fabric: knit type, wale and course count per inch, Finishes: chemicals such as resins, starches, waxes and mechanical effects such as. The amino acidic pattern of sulfated silk remained essentially unchanged for short reaction times (< or =2 h). Alkaline solutions cause the silk filament to swell. The tensile properties of different varieties of silks in terms of tenacity, elongation-at-break and initial modulus have been determined by a number of workers. The wool fibers have a natural crimp and they hold onto other fibers strongly which makes the fabric aslo very strong. Hand characteristic are the changes of the fabric plane with hand manipulations, which exert tensile compression, molding, or supporting forces on the fabric.

Surely, the above physical and chemical properties of silk fiber will help us to be careful about the processing of silk in the different stages of processing from spinning to garment making. It also can be simply clean by delicate soaps and cleansing. These fibers exhibit favorable heat-insulating properties but owing to their moderate electrical resistivity, they tend to build up static charge. Cotton and linen are made from short plant fibres that are spun together to make longer threads. Resilient and durable. Strength: Though fibroin is not severely affected by hydrogen peroxide solution, nevertheless may suffer from the reduction of nitrogen and tyrosine content of silk indicate that hydrogen peroxide may cause breakage of peptide bonds at the tyrosine residues resulting in the weight loss of the fiber. The absorption of water molecules takes place in the amorphous regions of the fiber, where the water molecules compete with the free active side groups in the polymer system to form cross links with the fibroin chains. When it will remain unaffected for prolonged periods at 1400C but it decomposes at 1750C. Unless left for time in damp state or underneath extreme conditions of tropical damp it will unaffected.
