Definitions to know

Denier is an international system for measuring the weight (linear density) of fabric. Officially, it is the number of unit weights of 0.05g/ 450m length. It is a direct numbering system in which the lower numbers represent the finer sizes and the higher numbers the coarser sizes. In the U.S., the denier system is used for numbering filament yarns (except glass), manufactured fiber staple (but not spun yarns) and tow (continuous filaments, such as nylon, polyester, etc., that have no definite twist). In most other countries, the denier system has been replaced by the tex system (a system for linear density equal to the weight in grams of 1km of yarn, filament, fiber or other textile strand).

Hand is the feel of a fabric to the touch.

Wicking occurs when moisture accumulates at the edge of a fabric where substrate yarns may be exposed, or in sewn seams where threads come in contact with the substrate.

Scrim is an open-constructed fabric used as a base material in coated and laminated fabrics.

Warp refers to the threads that run through the length of a roll of fabric.
