Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The following terms shall be stated on the law label when
				  applicable in addition to other labeling nomenclature required by these
				  regulations for defining the chemical composition of manufactured
				  fibers.
(a) "Acetate": a manufactured
				fiber in which the fiber-forming substance is cellulose acetate. Where not less
				than 92% of the hydroxyl groups are acetylated, the term triacetate may be used
				as a generic description of the fiber.
(b) "Acrylic": a manufactured fiber in which
				the fiber-forming substance is any long chain synthetic polymer composed of at
				least 85% by weight of acrylonitrile units.

(c) "Azlon": a manufactured fiber in which
				the fiber-forming substance is composed of any regenerated naturally occurring
				proteins.
(d) "Glass": a
				manufactured fiber in which the fiber-forming substance is glass.
(e) "Metallic": a manufactured fiber composed
				of metal, plastic-coated metal, metal coated plastic or a core completely
				covered by metal.
(f) "Modacrylic":
				a manufactured fiber in which the fiber-forming substance is any long chain
				synthetic polymer composed of less than 85% but at least 35% by weight of
				acrylonitrile units

(g) "Nylon": a manufactured fiber in which
				the fiber-forming substance is any long chain synthetic polyamide having
				recurring amide groups (-C-NH-) as any integral part of the polymer chain.

(h) "Nitrile": a manufactured fiber
				containing at least 85% of a long chain polymer of vinylidene dinitrile
				(CH2-C(CN)2-) where the
				vinylidene dinitrile content is no less than every other unit in the polymer
				chain.
(i) "Olefin": a manufactured
				fiber in which the fiber-forming substance in any long chain synthetic polymer
				composed of at least 85% by weight of ethylene, propylene or other olefin
				units.
(j) "Polyester": a
				manufactured fiber in which the fiber-forming substance is any long chain
				synthetic polymer composed of at least 85% by weight of any ester of a dihydric
				alcohol and terephathalic acid
				(p-HOOC-C6H4-COOH-).
(k) "Rayon": a manufactured fiber composed of
				regenerated cellulose, as well as manufactured fibers composed of regenerated
				cellulose in which substituents have replaced not more than 15% of the hydrogen
				of the hydroxyl groups.
(l)
				"Saran": a manufactured fiber in which the fiber-forming substance is any long
				chain synthetic polymer comprised of at least 80% by weight of vinylidene
				chloride units
				(-CH2CCL2-).
(m) "Spandex": a manufactured fiber in which
				the fiber-forming substance is a long chain synthetic polymer composed of at
				least 85% of segmented polyurethane.
(n) "Vinyl": a manufactured finer in which
				the fiber-forming substance is any long chain synthetic polymer composed of at
				least 50% by weight of vinyl alcohol units (-CH2-CHOH-),
				and in which the total of the vinyl alcohol units and any one or more of the
				various acetal units is at least 85% by weight of the fiber.
(o) "Vinyon": a manufactured fiber in which
				the fiber-forming substance is any long chain synthetic polymer composed of at
				least 85% by weight of vinyl chloride units
				(-CH2-CHCL-).
(p) "Rubber": a manufactured fiber in which
				the fiber-forming substance is comprised of natural or synthetic rubber,
				including the following categories:
(1) A
				manufactured fiber in which the fiber-forming substance is a hydrocarbon such
				as natural rubber, polyisoprene, polybutadiene, copolymers of dienes and
				hydrocarbons, or amorphous (non-crystalline) polyolefins.
(2) A manufactured fiber in which the
				fiber-forming substance is a copolymer of acrylonitrile and diene (such as
				butadiene) composed of not more than 50% but at least 10% by weight of
				acrylonitrile units . The term "laetrile" may be used as a generic description

for fibers falling within this category.
(3) A manufactured fiber in which the
				fiber-forming substance is a polychloroprene or a copolymer of chlorophene in
				which at least 35% by weight of the fiber-forming substance in composed of
				chloroprene units
