Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.. A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or human-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of ...
Polyester/polyester core spun thread is made by wrapping staple polyester around a continuous polyester filament during spinning and plying these yarns into a sewing thread. [ 3 ] Measurement types and labeling
The product is continuous strands. These are called filament yarns. Examples of synthetic fibers are polyester, polyamide, and acrylic. Silk is the only natural fiber obtained as a filament. [22] [5] [6] If filament fiber is cut into discrete lengths, it becomes staple fiber.

As a spinner spins, they will often stop every few minutes to check to see that the number of twists per inch is the same throughout the yarn, as well as that the number of wraps per inch (the thickness of the yarn) is the same. Measuring the number of twists per inch while spinning singles also helps the spinner create a balanced yarn when ...

The main exception is for cloths used for facial cleansing and for the removal of skin oils (sebum), sunscreens, and mosquito repellents from optical surfaces such as cameras, phones and eyeglasses wherein higher-end proprietary woven, 100% polyester cloths using 2 μm filaments, will absorb these types of oils without smearing.
Polycyclohexylenedimethylene terephthalate (PCT) is a thermoplastic polyester formed from the polycondensation of terephthalic acid and cyclohexanedimethanol. [1] Its chemical structure is similar to that of polyethylene terephthalate (PET), with which it shares properties like dimensional stability and chemical resistance.
