Common Phrases Explained
T-shirt manufacturers use many terms to explain their merchandise. The terms usually are not at all times constant and it helps to have a reference guide.
The following is the official Green Man T-Shirts Guide to understanding t-shirt terms:
20s, 20/1, 20s single: Unit of measurement that defines the fineness of cotton thread. A typical spool of single-ply cotton thread is comprised of 840 yards of cotton thread. If it takes 20 spools to weigh one pound, then the thread on those spools is known as 20s cotton, or 20/1. If 30 spools weigh one pound, then the thread on these spools is known as 30s cotton thread, or 30/1. If it takes 40 spools to weigh one pound, then the thread on those spools is known as 40s cotton, or forty/1. The higher quantity means a finer thread, and thus a finer, softer fabric is created. T-shirts made of 30s and 40s are softer, finer, and have better drape than t-shirts fabricated from 20s. The phrases are used many ways, but it’s the number that counts; “20s,” “20/1,” and “20 singles” are the identical. Threads could be twisted collectively into thicker strands. If two 20/1 cotton threads were twisted together, it can be referred to as 20/2.
