T-shirt manufacturers use many terms to spell it out their items. The terms usually are not always consistent and it also helps to experience a reference guide.
The following is the official Green Man T-Shirts Secrets for understanding t-shirt terms:
20s, 20/1, 20s single: Unit of measurement that defines the fineness of cotton thread. An ordinary spool of single-ply cotton thread includes 840 yards of cotton thread. When it takes 20 spools to weigh one pound, then this thread on those spools is known as 20s cotton, or 20/1. If 30 spools weigh one pound, then the thread on those spools is called 30s cotton thread, or 30/1. When it takes 40 spools to weigh one pound, then the thread on those spools is called 40s cotton, or 40/1. The bigger number means a finer thread, therefore a finer, softer fabric is established. T-shirts manufactured from 30s and 40s are softer, finer, and still have better drape than t-shirts crafted from 20s. The terms are widely-used numerous ways, but it's the telephone number that counts; "20s," "20/1," and "20 singles" are exactly the same. Threads is often twisted together into thicker strands. If two 20/1 cotton threads were twisted together, it might be generally known as 20/2.
Bamboo Fabric: Rayon produced from bamboo cellulose. Although rayon is actually a man-made synthetic material, most professionals agree it truly is readily biodegradable. Bamboo fabric is especially soft and possesses excellent drape.
Bamboo: Fast growing plant, classified as a grass, which may be readily processed into rayon to produce bamboo rayon clothing.
Bleach Wash: A procedure that utilizes bleach to soften and distress the design of the fabric being washed.
Boat Neck: An incredibly wide neckline that runs throughout the collarbone area into the shoulder points. Derives from early sailors' shirts, where wide neck enabled quick removal in the event the sailor fell overboard.
Boy Beater: Women's fashion answer to the wife beater. A women's tank top, although it can be any color.
Brushed Cotton: A way to clear out excess lint and fibers from cotton fabric. Brushed cotton usually features a very soft, smooth finish.
Burn-Out: An operation which uses sulfuric acid or another strong acid to "burn-out" aspects of a fabric knit, usually a polyester/cotton blend. The method gives a see-through, very sheer effect.
Cap Sleeves: Usually describes shorter sleeves on women's garments.
Carbon Dioxide: CO2. A chemical compound comprised of two oxygen atoms then one carbon atom. Called a "greenhouse" gas due to the relationship with climate change. Several t-shirt manufacturers are now measuring and recording the CO2 emissions related to manufacturing their shirts.
Carbon Trust: Independent organization founded in 2001 in Great Britain that monitors carbon emissions. The Carbon Trust works together with companies to help lessen their carbon footprint, and today certifies companies and products as possessing a "low carbon" or "no carbon" footprint. A handful of t-shirt companies now manufacture "low carbon footprint" t-shirts.
