May 23, · PHYSICAL PROPERTIES • Color: The color of silk fiber could be yellow, brown, green or grey. • Strength: Silk is a strong fiber. The wet strength of silk is higher than dry strength. Spider dragline silk, which exhibits extraordinary strength and toughness, is primarily composed of two related proteins that largely consist of repetitive sequences. In most spiders, the repetitive region of one of these proteins is rich in prolines, which are not present in the repetitive region of the other . The absence of prolines in one component was previously speculated to be Cited by:
The silk reeling techniques are excellent methods to produce superior grade raw silk which is used by the textile industry to produce exotic fabric. Silk reeling is the final and purely commercial phase of sericulture. It is concerned with unwinding of the silk filaments of the cocoon.

In this paper, the different physical properties of the eri and mulberry cocoon and their filament were evaluated. Even though the method of rearing, handling, and harvesting of the cocoons is poor, the physical properties of the silk produced in Ethiopia fall within the limits of commercial cocoons produced in major silk producing countries.

Physical physical properties of silk filaments book. Silk fibers from the Bombyx mori silkworm have a triangular cross section with rounded corners, 5–10 μm wide. The fibroin-heavy chain is composed mostly of beta-sheets, due to a mer amino acid repeat sequence with some variations.
The flat surfaces of the fibrils reflect light at many angles, giving silk a natural sheenSimplified Chinese: 丝. The important physical characteristics of different silks include the silk filament length, fiber fineness, and fiber density.
Silk filaments are extracted from a cocoon by a process known as reeling. During reeling, 8–10 ends of silk filaments drawn from an individual cocoon are held together to form a. In this paper, the different physical properties of the eri and mulberry cocoon and their filament were evaluated.

Silk fi bres display unusual mechanical properties: they are strong, extensible and mechanically compressible (Matsumoto et al., ).
Silk is rightly called the ‘queen of textiles’ for its lustre and feel (Manohar Reddy, ). - properties similar to flax, but stronger and more lustrous - per book, strongest of natural fibers and most crystalline - low resilience and flexibility; high modulus - excellent absorbency, dyes rapidly, good resistance to attack by microorganisms - expensive to process, which has limited commercial use.
Silk fibers from Bombyx mori silkworm was degummed with different concentration of citric acid, and the physical properties and fine structure were investigated to elucidate the effects of citric. Dec 25, · Silk filaments can display marked structural and morphological variations along their length.
The physical structure of the filaments is known to be influenced by processing conditions. Physico‐chemical Aspects of Textile Coloration. The atmospheric conditions and other facilities to rear silk filaments are good in Ethiopia. In Awassa, Awash Melkassa, and Kombolcha silk rearing is started with good progress.

Humans have long appreciated silk for its lustrous appeal and remarkable physical properties, yet as the mysteries of silk are unraveled, it becomes clear that this outstanding biopolymer is more than a high‐tech fiber.

Spider dragline silk shows the highest toughness in comparison to all other known natural or man-made fibers. Despite a broad experimental foundation concerning the macroscopic silk thread properties as well as a thorough simulation-based molecular understanding, the impact of the mesoscale building blocks, namely nano-/submicrometer-sized filaments, on the mechanical properties of the threads Cited by: 6.
Silk fiber produced by the larvae of Trichoptera (caddisflies) and Lepidoptera (moths and butterflies) is composed of two filaments embedded in a layer of glue proteins. In an aerial environment Lepidoptera spin silk filaments assembled from heavy chain fibroin (H-fibroin), light chain fibroin (L-fibroin), and the glycoprotein PCited by: A method for the treatment of spider silk filament for use as a thread or composition in the manufacture of cosmetic, medical, textile, and industrial applications, wherein the spider silk filament, derived from genetically modified organisms, is treated with at least one component selected from the group consisting of vitamins, hormones, antioxidants, chelating agents, antibiotics, preserving Cited by: 4.
Velvet is a name of the method of weaving fabric, not the fabric, i.e. silk or cotton. Velvet weave can be made of any fabric. Terms “Pile” refers to the fibers that stick up from the surface and give velvet its characteristic soft fuzzy surface. “Nap” refers to the direction that those fibers lie.

Spider silk is a filamentous natural protein fiber produced by the spiders. Dragline silk produced by the spider offers superior properties t han many of the natural and syntheticfibers.
The natural spinning process, chemical composition, structure and properties of spider silk had remained mystery for a long johnsonout.com by: Handbook of Properties of Textile and Technical Fibres, Second Edition introduces tensile properties and failure and testing of fibers, also examining tensile properties and the failure of natural fibers, such as cotton, hemp, flax, agave, wool and silk.
Next, the book discusses the tensile properties and failure of synthetic fibers, ranging from polyamide, polyester, polyethylene and carbon. Aug 14, · Physical properties of textile fibres Because of this connection, it is appropriate to start this book on the physical properties of fibres with a review of what is known about their structure.
There is much detail, only partly superseded by more recent work, in the book edited by Hearle and Peters  and the review by Hearle and Greer [2.Physical properties of materials Mary Anne White Designed for advanced undergraduate students, Physical Properties of Materials, Second Edition establishes the principles that control the optical, thermal, electronic, magnetic, and mechanical properties of materials.May 01, · Physical properties • Thermal properties - Silk is more sensitive to heat than wool.
• Hand feel - The handle of the silk is described as a medium and its very crystalline polymer system imparts a certain amount of stiffness to the filaments.
