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 ...
Nylon is a family of synthetic polymers characterized by amide linkages, typically connecting aliphatic or semi-aromatic groups.. Nylons are generally white or colorless [1] [failed verification] [2] [failed verification] and possess a soft texture, with some varieties exhibiting a silk-like appearance.
An assortment of different colors of thread Red thread bobbin Multi-colored stranded embroidery floss. A thread is a long strand of material, often composed of several filaments or fibres, used for joining, creating or decorating textiles.
Caprolactam molecule used to synthesize Nylon 6 by ring opening polymerization. Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide.Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers.
Filament yarn consists of filament fibres (very long continuous fibres) either twisted together or only grouped together. Thicker monofilaments are typically used for industrial purposes rather than fabric production or decoration. Silk is a natural filament, and synthetic filament yarns are used to produce silk-like effects.
[1] [2] Nylon 46 is an aliphatic polyamide formed by the polycondensation of two monomers, one containing 4 carbon atoms, 1,4-diaminobutane , and the other 6 carbon atoms, adipic acid, which give nylon 46 its name. It has a higher melting point than nylon 6 or nylon 66 and mainly used in applications which must withstand high temperatures.
In 1938, a research director for Thann & Mulhouse, Joseph Zeltner, first conceived the idea of Nylon 11, which was suggested in the works of Wallace Carothers. [3] Thann & Mulhouse had already been involved in processing castor oil for 10-undecenoic-acid, which would eventually be converted into the first amount of 11-aminoundecanoic acid in 1940 with the help of coworkers Michel Genas and ...
DuPont made public in 1938 that their company had invented nylon. [1] This new invention was the first synthetic fiber, fabrics that are commonly used in textiles today. [2] In 1939, DuPont began marketing nylon monofilament fishing lines; however, braided Dacron lines remained the most used and popular fishing line for the next two decades, as early monofilament line was very stiff or "wiry ...
