The ACT Glossary of Textile Terms has been compiled by members of the ACT Education Committee as a guide for interior designers, specifiers, ACT members, and other interested parties to most of the terminology commonly used in the contract textile industry.
The Glossary is being posted on the ACT website to enable the addition of new terms and definitions as they come into use. Members of the ACT organization have reviewed and cross referenced the contents of this document for accuracy and completeness. ACT however is not responsible or liable for the interpretation or use of any terms published herein.

abrasion resistance: Ability of a fiber, yarn, or fabric to maintain physical properties or appearance despite surface friction. Such friction may result from rubbing against another material or against itself. Abrasion resistance is an important element in the durability of fabric. Common methods for testing fabric abrasion resistance include Wyzenbeek, Martindale, and Taber test methods. See also durability and pilling.
acetate: A fiber manufactured by treating purified cellulose refined from cotton linters or wood pulp. The resulting flakes are dissolved in acetone to make a spinning solution that can be made into continuous filament or staple fiber. Acetate fabrics are wrinkle-, shrink-, moth-, and mildew-resistant. They have a luxurious feel and appearance, as well as excellent drapabilty.
accreditation: Official authorization to conduct certification activities against a standard (i.e., for organic textiles).

Bow is measured by drawing a line perpendicular to the selvage at the point where the arc crosses the selvage. The maximum deviation of the arc from the perpendicular line is measured and recorded. Generally no more than one inch of bowing is acceptable. See also skew.
breaking strength: The load required to rupture fiber, yarn, or fabric during a tensile test. Breaking strength is commonly referred to as the “tensile strength” of the material. The most commonly cited breaking-strength test for contract fabrics (ASTM D5034 the ‘grab’ method) consists of mounting rectangular fabric specimens in the jaws of a suitable tensile testing machine, and moving the jaws apart in the same plane as the fabric under specific conditions until the fabric ruptures. Breaking strength is reported as the average amount of force required to cause rupture of the specimens. Note that “breaking strength” is not a term used to describe the tear resistance of a fabric.

Brocades are often used for drapery, upholstery, eveningwear, and other decorative purposes.
brush pill test ASTM D3511: One of several test methods designed to assess the propensity of a fabric to form fuzzy balls on the surface due to abrasion during use. The Brush Pill test consists of first rubbing fabric specimens in a circular motion against a standard nylon brush under specific load conditions in order to raise fibers from the surface of the fabric. The second part of the test consists of rubbing pairs of brushed specimens against each other using the same motion and the same load conditions to induce the formation of pills. The specimens are then rated for pill frequency by comparing them to a series of reference photographs representing a five-step scale: Class 5 = No pilling Class 4 = Slight pilling Class 3 = Moderate pilling Class 2 = Severe pilling Class 1 = Very severe pilling See also pilling.

California Technical Bulletin 133 (CAL TB 133): A large, open-flame test for upholstered seating developed by the California Bureau of Home Furnishings and Thermal Insulation. The test is required for seating in certain California, Boston, NY/NJ Port Authority, and other occupancies. The test is intended to qualify upholstered furniture for use in “high-risk” occupancies such as healthcare facilities, penal institutions, daycare facilities, and buildings where free and easy egress is not always possible during a fire evacuation. CAL TB 133 is a test for furniture; it is not a fabric test. The test method consists of exposing the seating area of upholstered furniture to an intense flame from a square-shaped burner for 80 seconds. The testing takes place in a standard room instrumented to record the mass loss of the test object, the temperature at the ceiling and at the 4-foot level, and smoke opacity at the 4-foot level. Exhaust gases are collected and analyzed for carbon monoxide (CO) generation and to determine both the peak heat release and the total heat release of the burning furniture.
