Abstract
Disclosed is a method of protecting glass optical fiber preforms and glass precursor elements for making optical fiber preforms, wherein the preform or glass precursor element is stored within a protective bag. The protective bag preferably has anti-static agents incorporated therein. The protective bags can be employed to protect any glass precursor element used in making optical fiber preforms, for example, glass core canes, glass tubes, or the optical fiber preforms themselves.
Claims17
A method of making an optical fiber comprising:
- providing an optical fiber preform comprising silica or a glass precursor article used to form the optical fiber preform, or a ceramic mandrel substrate for receiving glass soot used to form the optical fiber preform;
- and
- storing the optical fiber preform or the glass precursor article or the ceramic mandrel substrate in a protective bag prior to the optical fiber being drawn from the optical fiber preform, wherein the protective bag is formed from a polyolefin-based material, wherein the polyolefin-based material includes an anti-static additive selected from the group consisting of (a) N,N-Bis(hydroxyethyl)laurylamide, (b) a mixture of octadecanoic acid monoester with 1,2,3 propanetriol, (c) N,N-Bis(hydroxyethyl) C13-C15 alkyl amine, and (d) combinations thereof.
