What are the types of textured yarns?
The following types of textured yarns are distinguished by production method, properties, and use: high-tensile, low-tensile, crimped, loop, shaped, bicomponent, combination, and high-bulk yarns.
What type of yarns are textured in chemical Texturising?
Thermoplastic yarns, like Polyamides and Polyester, are especially suitable for texturing. Texturing process where the yarn goes through friction discs that create a twist which is then immediately fixed by heat.
Why textured yarns are used?
Texturizing processes make yarns more opaque, improve appearance and texture, and increase warmth and absorbency. Textured yarns are synthetic continuous filaments, modified to impart special texture and appearance.
What are the different methods of texturing?
Texturizing methods includes false twist texturizing, edge crimping, stuffer box, knit-de-knit and air jet texturizing. In this article we will discuss false twisting, stuffer box, Halenca process and edge crimping method of texturing.
What is texturing process?
Texturising or texturizing is the process by which synthetic fibres are modified to change their texture – the physical appearance of the fibre. Texturising techniques can include bulking (where thermoplastic fibres are twisted, heat set and untwisted), crimping and coiling, amongst others.
What is FDY yarn?
Fully Drawn Yarn (FDY) is produced by a process similiar to POY manufacturing except that the yarn is produced at higher spinning speeds coupled with intermediate drawing integrated in the process itself. … Yarns are produced by a continuous polymerisation process.
How many types are there of novelty yarns?
Novelty yarns are classified according to the single or ply structure: Single yarns are Tweed and Slub Yarns. Ply Yarns are Ratine, Spiral, Knot, Snarl and Boucle. Apart from these, there are many other novelty yarns like Chenille, Flake, metallic and textured yarns.
