Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.. A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or human-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of ...
Vinyl coated polyester is a material frequently used for flexible fabric structures. It is made up of a polyester scrim , a bonding or adhesive agent, and an exterior PVC coating. The scrim supports the coating (which is initially applied in liquid form) and provides the tensile strength, elongation, tear strength, and dimensional stability of ...
Thus one can roughly find the number of twists per inch for the single, or one can use the doubled back yarn as a measure. With a thick-and-thin yarn, it is best to count the twist over several inches and average the results. [2] This is because the number of twists per inch will tend to vary between the thin and thick sections.
Adidas <ADSGn.DE> will launch new fabrics made from recycled polyester and marine plastic waste and expand the product lines that use them after the success of shoes made with the Parley for the ...
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%.
Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.

Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness . High specific modulus materials find wide application in aerospace applications where minimum structural weight is required.
