Definitions

• the present invention relates to a process for lubricating synthetic and natural fibers which comprises applying to the fiber a coning oil which has incorporated therein a polysiloxane copolymer consisting of units of the unit formulae a)zSiO, (B) (C 3)(C11 2u+l) O, and
• This invention relates to a process of applying a lubricant to a fiber and more particularly to a lubricant that effectively facilitates processing and which possesses the unique and added advantage of being easily and readily removed from the fiber prior to subsequent operations or ultimate use.
• the fiber when natural or numerous synthetic fibers are processed prior to knitting or the like, the fiber must be immersed in a coning oil such as mineral oil, butyl stearate, and fatty acids among others to insure an efiicient and productive capacity.
• a coning oil such as mineral oil, butyl stearate, and fatty acids among others to insure an efiicient and productive capacity.
• the fiber following the initial or early processing stages, the fiber is wound about conical containers.
• the use of the coning oil serves a dual purpose; (1) it provides lubricity to increase the rate of processing, and (2) it imparts to the fiber, a surface tackiness of a consistency such that the fiber will remain in position upon the conical container and will not tend to sag or drop to the lower portion of the container which may disrupt production.
• the coning oil cannot provide too great a surface tackiness or when the fiber is unwound for further processing or use, it will stick and interfere with normal operations. Following the above processing stage and prior to ultimate use or subsequent operations, e.g., dying, the residual coning oil must be removed from the fiber. Removal of the coning oil is generally achieved by scouring and other cumbersome methods, however, an inherent disadvantage exists in that the coning oil is sufliciently diificult to remove so that 3,493,425 Patented Feb. 3, 1970 much of it remains on the fiber resulting in countless problems. Also, because the coning oil is especially difficult to remove, considerable expense is encountered due to the fact that removal of the coning oil requires a tremendous increase in labor costs and the like.
• This invention relates to a process for lubricating fibers which comprises applying to the fiber a coning oil, the improvement comprising as an additive to the coning oil, a polysiloxane copolymer consisting of units of the unit formulae 3)3 (B) (CH3) (C H2n+1)SiO, and (C) (CHQSIQ I (C2 4 l )x in which R is a member selected from the group consisting of a hydrogen atom, a hydrocarbon radical containing less than 9 carbon atoms,
• 3 0R radical, and alCN R radical n has a value of at least 9, x has a value of at least 6, and
• (B) Is present in an amount of from 32 to 38 weight percent based on the weight of (A) +(B) +(C), and
• (C) Is present in an amount of from 36 to 44 weight percent based on the weight of (A) +(B)+(C).
• R radical when it is a hydrocarbon radical containing less than 9 carbon atoms are the methyl, ethyl, propyl, isopropyl, butyl, hexyl, phenyl, tolyl, and allyl radicals, etc.
• n has a value of at least 9, hence that radical can be represented as an alkyl radical such as the nonyl, decyl, hendecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, heneicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, triacontyl, tetracontyl, pentacontyl, and hexacontyl radical, among others.

• coning oil as used herein, it is simply meant a lubricant which is applied to both natural and synthetic yarns which assists in the further processing of yarns to piece goods, i.e., knitting and weaving.
• the term coning oil includes material such as mineral oil, butyl stearate, polyethylene oxides, glycol esters, fatty acids and fatty amides, etc. However, for practical considerations and the like, for most operations, mineral oil is generally preferred.
• the polysiloxane copolymers of the present invention can be endblocked by various groups including triorganosiloxy groups wherein the organo groups are the methyl, phenyl, ethyl, vinyl, and trifluoropropyl group; hydroxyl groups, and methyl radicals bonded to the termial silicon atoms through an Si-C bond, among many others.
• the weight percentages of (A), (B), and (C) are especially critical if the objects of this invention are to be achieved. Since very specific properties are of prime importance, the weight percentages heretofore related are of particular significance.
• the above combination provides a polysiloxane cpolymer which exhibits both lubricity and self-emulsifiable characteristics.
• it when added to the coning oil, it enhances lubricity for purposes of processing and since it is also self-emulsifiable, it can be easily removed upon simple contact with water, thus precluding the cumbersome scouring procedures which were previously necessary.
• this very specific additive in effect, lifts the coning oil off the surface of the fiber when subjected to water and acts as an internal scouring agent itself; thus making its use both beneficial and attractive to the textile industry.
• the synthetic fibers that can be so treated include acrylic fibers in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85 percent by weight of acrylonitrile units; modacrylic fibers in which the fiber-forming substance is any long chain synthetic polymer composed of less than 85 percent but at least 35 percent by weight of acrylonitrile units; polyester fibers 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 dihydric alcohol and terephthalic acid; Saran fibers in which the fiber-forming substance is any long chain synthetic polymer composed of at least 80 percent by Weight of vinylidene chloride units; azlon fibers in which the fiber-forming substance is composed of any regenerated, naturally occurring proteins; nytril fibers in which there is at least 85 percent of a long chain polymer of vinlyidene dinitrile where the vinylidene dinitrile content is no less than every other unit in the polymer chain; nylon fibers in which the fiber-forming substance is
• natural fibers such as cotton, wool, etc. can be so treated to derive the aforementioned advantages.
• the amount of the polysiloxane additive incorporated in the coming oil is not particularly critical with the exception that it be present in a sufficient quantity to impart the desired properties. Therefore, it has been found that approximately 0.5 percent to percent of the polysiloxane additive based on the weight of the coning oil is a perfectly satisfactory amount to achieve the desired effects.
• polysiloxane additive of this invention is also potentially useful when employed alone as a fiber finish where unique compatibility is required. For example, to finish tire cord yarns where the cord is placed in the rubber and the finish does not affect subsequent adhesion.
• the yarns were then subjected to simple washing by merely spraying the fibers with water. Subsequent analysis of the fiber confirmed that virtually no residual lubricant remained.
