|
|
Term
|
Definition
| describes the ability of a fabric or pile to return to its original thickness after compression |
|
|
Term
|
Definition
| refers to a polymer composed of more than one type of mer |
|
|
Term
|
Definition
| describes a fiber-finishing step in which a manufactured fiber is elongated after spinning to alter the molecular arrangement within the fiber, increasing crystallinity and orientation and resulting in a change in specific performance properties. |
|
|
Term
|
Definition
| a fiber-forming process in which a solution of polymer dissolved in a solvent is extruded; the fiber coagulates as the solvent evaporates |
|
|
Term
|
Definition
| a generic subclass of a stretch polymer |
|
|
Term
|
Definition
| a spinning method in which the dissolved polyethylene polymer forms a viscous gel in the solvent, followed by extrusion through the spinneret, solvent extraction, and fiber drawing |
|
|
Term
|
Definition
| a flattening of the cross section of heat-sensitive fibers of yarns resulting from exposure to high temperatures |
|
|
Term
|
Definition
| a type of copolymer; another type of mer is attached to the backbone polymer chain |
|
|
Term
|
Definition
| the ability to soften, melt, or shrink when subjected to heat |
|
|
Term
|
Definition
| describes the process of producing fiber, yarn, or fabric stability through the use of heat |
|
|
Term
|
Definition
| fibers that have been modified in the spinning process to increase fiber strength |
|
|
Term
|
Definition
| refers to a polymer composed of a single type of mer |
|
|
Term
|
Definition
| a generic subclass of an elastic olefin |
|
|
Term
|
Definition
| have been engineered to have a lower flex life, thus decreasing pill formation |
|
|
Term
|
Definition
| the process of producing fibers by melting polymer chips and extruding the melt (the molten polymer) in fiber form. coagulation occurs by cooling |
|
|
Term
| moisture vapor transport rate (mvtr) |
|
Definition
| measures how quickly moisture vapor moves from the side of the fabric next to the body to the fabric's exterior side |
|
|
Term
|
Definition
| a manufactured fiber in which the fiber-forming substance is any long-chain synthetic polyamide in which less than 85 percent of the amide linkages are attached directly to two aromatic rings |
|
|
Term
|
Definition
| a manufactured fiber in which the fiber-forming substance is any long-chain synthetic polymer composed of at least 85 percent by weight of ethylene, propylene, or other olefin units except amorphous (noncrystalline) polyolefins qualifying as rubber |
|
|
Term
|
Definition
| refers to fibers that have a high affinity or attraction for oil |
|
|
Term
|
Definition
| the formation of tiny balls of fiber ends and lint on the surface of the fabric |
|
|
Term
|
Definition
| a special-use fiber made from polyetherimide |
|
|
Term
|
Definition
| a manufactured fiber in which the fiber-forming substance is any long-chain synthetic polymer composed of at least 85 percent by weight of an ester of a substituted aromatic carboxylic acid, including but not restricted to substituted terephthalate units or substituted hydoxybenzoate units |
|
|
Term

|
Term
|
Definition
| produced from synthetic polymers made from basic raw materials |
|
|
Term
