It's called spinning.
Individual fibers are spun into yarn.
The main difference between polyester staple fiber yarn and polyester filament yarn is that polyester staple fiber yarn is made up of chemicals. Polyester filament yarn contains both man-made and natural fibers.
fib
Tencel is a staple fibre. That is it is cut into staple lengths during production so that it can be processed into yarns and nonwoven fabrics on conventional textile processing machinery. The cut lengths are similar in length to cotton or to wool. Continuous filament Tencel yarns are not produced but in theory could be. In a filament yarn all of the fibres in the yarn have the same length as the piece of yarn.
A yarn in which one type of fiber is twisted or wrapped around another fiber that serves as a core.
The cellulosic manmade fiber industry comprises establishments primarily engaged in manufacturing rayon and acetate fibers in the form of monofilament, yarn, staple, or tow.
Twill is a weaving pattern. Cotton used in twill weaving is a staple commodity.

Textile engineering deals with the process of making a yarn from cotton ,called as spinning.Also we study about the process of conversion of yarn to fabric ,called as weaving.Also we study about dying the the yarn or fabric ,called as Textile chemical processing and also we study about recent trends and methods.
Textured yarn has for lack of better words a texture like confettie, eyelash, or fiber look to it. Micro yarn is very thin yarn.
Microfiber means the staple size in the yarn. Microdenier defines the polyester yarn lessthan 1 Denier
Sock yarn, as its name implies, is generally made from standard yarn. However, sock yarn can be made from virtually any form of fiber, such as wool or nylon.
