Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.
Organdy was a useful material as a Casement cloth, sheers, and lining etc. [1] In the late 19th through mid 20th centuries, young girls wore dresses made of organdy. [6] In the 21st century, this material has fallen out of favor in the childrenswear market because of its tendency to wrinkle, which can be attributed to its stiffness. [ 4 ]
Polyester-cotton blended clothing is more comfortable to wear in humid climates than polyester alone. [1]: 79 A heavy pair of jeans made of 100% cotton that weigh 14 oz (396.9 g) can be cut down to 11 oz (311.8 g), without compromising durability, by changing the composition to a blend of polyester 50% with cotton or nylon 20%.

It is widely used in the manufacture of insulation and textiles. gossamer
Fabric softeners impart soft hand feel to the treated fabrics. [3] Silk surfacing a surface finishing of cotton to obtain an appearance similar to silk. [8] Plissé is chemical finish in which the fabrics are treated with sodium hydroxide to obtain a puckering effect. [9] Deweighting, or weight reduction, is a treatment for polyester to make it ...
Cationization of cotton is an electro kinetic phenomena ( zeta potential and electro kinetic) for surface charge of cotton. The cotton surface is charged with negative ions. Cationization alters the characterization of the surface of the cotton which allows salt free dyeing and improves the dye ability of cotton. The process involves the ...
Post-consumer cotton is textile waste that is collected after consumers have discarded the finished products, such as used apparel and household items. [1] Post-consumer cotton which is made with many color shades and fabric blends is labor-intensive to recycle because the different materials have to be separated before recycling. [1]
