A staple fibre is a short fibre
A filament fibre is a long fibre
it has nothing to do with being man made or natural
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.
I think it's a ply yarn. This is because the staple yarns are wrapped around the filament yarns.
Sport weight yarns are usually thinner and lighter weight than worsted weight yarns
In a woven fabric, skew is a measure of by how much the filling yarns are not perpendicular to the warp yarns. Bow is a measure of by how much the filling yarns deviate from being perfectly straight.
Yarns that are spun from short fibres, like cotton. The staple is the length of the fibre, so you might say 'Egyptian cotton is better quality than Indian cotton because it has a longer staple.' Many artificial yarns are extruded, that is made like squeezing toothpaste from a tube, so they don't need to be spun to make a long thread.
The basic difference between denim and non-denim jeans is as follows: Denim fabric's yarns are dyed before weaving the fabric. However, In Nondenims the greige yarns are woven and then greige fabric obtained is called RFD (ready for Dying), PFGD (Prepared for Garment dying) and Non denims. it could be any weave or twill.
Denier is a unit of weight indicating the fineness of fiber filaments and yarns that are woven together to make up the ballistic nylon.
A fibre can be a thin thread from either natural or synthetic sources, such as a seed hair from a cotton boll. Fibres are usually spun together to make continuous strands, which may be further combined by twisting. This is called a yarn. Yarns can be knitted, crocheted or woven into flat sheets which are called fabrics. However the terms are often used more loosely.
textile - originally, a woven fabric; now applied generally to any one of the following: (1) staple fibers and filaments suitable for conversion to or use as yarns, or for the Preparation of woven, knit, of nonwoven fabrics. (2) yarns made from natural or manufactured fibers. (3) fabrics and other manufactured products made with fibers as defined above from yarns. (4) garments and other articles fabricated from fibers, yarns, or fabrics when products retain the characteristics flexibility and drape of the original fabrics.this definition from the Academy of Textiles and Flooring Floorcovering Dictionary
Yarns worn at sea.
Warp yarns usually have more twist than weft yarns.
The plural of yarn is yarns. As in "the yarns are colourful".
