Abstract: The present invention provides a sparkling dyed double covered yarn comprising: (i) a core yarn; (ii) a first sheath yarn made of a bright polyamide yarn wound around the core yarn to form a single covered yarn; and (iii) a second sheath yarn made of a dyed polyamide yarn wound around said single covered yarn to form a double covered yarn; wherein the first sheath yarn and the second sheath yarn are wound in the same direction. The invention further provides processes for manufacturing a sparkling dyed double covered yarn and fabrics comprising the same.
Abstract: Provided is a process for manufacturing a polyamide yarn exhibiting good dyeability, while utilizing polyamide waste. The recycled polyamide yarn with a high waste polymer content is used for making quality articles by a low cost method, which is further friendly to the preservation of the environment.

Abstract: A process is provided for making a yarn with improved properties, such as lowered susceptibility to picks and snags. The yarn consists of a spandex core that is tightly covered with a nylon fiber, which tight covering is achieved by heat treatment. A knitted fabric is further provided, that is made of yarn consisting of a spandex core and a nylon fiber, which has low susceptibility to picks, as well as to tears during its production and its use.
