This comprehensive guide should provide readers with a deep understanding of sewing needles, from their historical significance to practical usage tips. Whether you’re a beginner or an experienced seamstress, the right knowledge about sewing needles can elevate your sewing projects and help you achieve professional results.
Elastomeric fibers are those fibers that possess extremely high elongations at break and that recover fully and rapidly from high elongations up to their breaking point. The fibers are all used in specialized applications where high elasticity is necessary within the textile structure. An Elastomer is a polymer with the physical property of elasticity. The elastomer is a term derived from elastic polymer, which is often used interchangeably with the term rubber.
Polyolefin fibers are those fibers produced from polymers formed by chain-growth polymerization of olefins (alkenes) and which contain greater than 85% polymerized ethylene, propylene, or other olefin units.
Threads are usually made up of several single strands twisted or plied together. The numbering system for threads has two parts: one related to the thickness of the single strand and the other to the number of strands (ply). Whereas the ply is expressed in thickness and the single strand is specified as a ?count? related to the length per unit weight. Cotton Count system, Tex system, and the Metric Ticket system are some of the commonly used thread numbering systems.
The polyamide fibers include the nylons and the Aramid fibers. Both fiber types are formed from polymers of long-chain polyamides.
Acrylic fibres are polymers formed by addition polymerization of at least 85% by weight of a chemical called acrylonitrile or vinyl chanide. To polymerise vinyl cyanide the double bond between the first two carbon atoms is broken and the molecules attach themselves to each other in a linear chain.
Polyesters are those fibers containing at least 85% of a polymeric ester of a substituted aromatic carboxylic acid including but not restricted to terephthalic acid and f-hydroxybenzoic acid.
Polymers are made up of many molecules all strung together to form really long chains. Things that are made of polymers look, feel, and act depending on how their atoms and molecules are connected.
Sewing Threads are manufactured by twisting short fibres or by continuous filaments yarns. At times two or more yarns are combined to make the thread to get the required strength.
Manmade protein fibers represent a promising and sustainable future for the textile industry. Their biodegradability, comfort, and versatility make them an attractive choice for eco-conscious consumers and businesses. As research and technology continue to advance, manmade protein fibers are likely to play a more significant role in creating textiles that are both environmentally friendly and high-performing. These fibers are a testament to the industry’s commitment to innovation and sustainability in the pursuit of a greener future. Manmade protein fibers are produced by dissolving proteins like casein from milk, soya bean protein, and zein from corn in diluted alkali and forcing these solutions through a spinneret into an acid-formaldehyde coagulating bath.
