Hilados obtenidos a partir de fibras texturadas. Parte II. Propiedades de los Hilados obtenidos.

Arun Naik, Federico López-Amo Marín


Synthetic fibres are mechanically crimped to facilitate their processing during the different stages of spinning. The crimp introduced is not stable and is gradually lost in the ensuing stages of processing. Textured polyester staple fibres are blended with cotton, and their processing behaviour with respect to the surfacegeometry components throughout the whole process is studied. The helicoidal waviness of the textured fibres favours hooking with other fibres of the blend or among themselves. The micro-crimp in the fibres is not only preserved during these processes, but in some cases it even increases because of the fibre's potential to contract on relaxing.
