A modern umbrella fabric has specific requirements for colour fastness to light, water and wet rubbing, and permeability. Serviceability in textiles or Performance is the ability of textile materials to withstand various conditions, environments, and hazards.
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is most commonly produced by certain insect larvae to form cocoons. [1] The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture).
The use of titanium dioxide (TiO 2) (as a catalyst/ co-catalyst for these reactions) has become an alternative way to minimize the formation of free formaldehyde and fabric strength loss. [10] DMDHEU is the most commonly used durable-press finish. In this process, the chemical is first applied to the fabric. Then the fabric is heated to allow ...
[1] Unspun short-fiber silk noil; see sericulture Tsumugi cloth, showing slubs. Silk is a filament fiber, and the only natural fiber type to come in filament length naturally (strands can be over 1.5 km long). However, some silk fibers are shorter in length, and must therefore be processed as shorter-staple fibers, not as filament fibers, to ...
The silk is known for its extreme durability and has a natural yellowish-golden tint [2] with a shimmering, glossy texture. [3] It was previously reserved for the use of royalty. [ 4 ] [ failed verification ] Muga is one of the three major types of indigenous wild silks produced in Assam, and is a key variety of Assam silk renowned for its ...
Italian silk polychrome damasks, 14th century. Damask (/ˈdæməsk/; Arabic: دمشق) is a woven, reversible patterned fabric. Damasks are woven by periodically reversing the action of the warp and weft threads. [1] The pattern is most commonly created with a warp-faced satin weave and the ground with a weft-faced or sateen weave. [2]
[1] [2] [3] To produce moire, ribbed rollers are used, and the ribs produce the watermark effect. The rollers polish the surface and make the fabric smoother and more lustrous. [4] High temperatures and pressure are used as well, [5] and the fabric is often damped before being run through the rollers. The end result is a peculiar luster ...
The silk produced is known for its glossy, fine texture and durability. It was previously reported that muga silk cannot be dyed or bleached due to "low porosity", but this is incorrect; muga takes dye like any other silk. This silk can be hand washed with its lustre increasing after every wash. Very often the silk outlives its owner.
