Coil oil and carried out using this coil oil Yarn processing method

The invention relates to an improved bobbin oil for treating yarns or threads in order to prevent the Oil during application to the yarn or threads and the subsequent yarn or thread processing to diminish.

Yarn or thread processors use to a large extent Spool oils, also known as processing or finishing oils.

The main function of a bobbin oil is to feed the thread or To give thread a lubrication and a good Garnbzw. Forming cone of threads that is the ideal feed package for most textile processing operations. A good cone is neither too hard nor too soft. He has a uniform density and he is different Similar to cones that are wound on different spindles. A good cone gives the yarn or the threads in a uniform manner for the next process, i.e. to the knitting gate, the shearing gate or the lace gate. Because of the spool oil used, a good cone will improve subsequent operations of knitting, shearing and lace-making.

Due to the increased consumption of bulky yarns in knitting factories, the Fiber manufacturer modern false-twist structuring devices. Thereby are primarily train-structured Yarns are used and after structuring, a bobbin oil is applied to the device and that Yarn becomes the reversing device or the silk twister for the subsequent knitting processes fed.

The silk twists also contain partially drawn or drawn yarn and a structuring device is used in them used, whereby the coil oil is applied to this same device and the Knitting devices are supplied in finished form for processing.

For the production of knitted or knitted goods, polyester and nylon threads are currently the predominant fiber pro-

-3-609821 / 0988

dukes However, as fashion dictates, the use of other fibers, e.g. rayon, acetate, Triacetate, acrylate, olefin, modified nylon (Nomex) Threads or mixtures of these threads increase. A coil oil should also be used for all of these fibers low spinability, as is aimed at according to the invention, can be used.

Spool oils are well-balanced products. They must be formulated in such a way that they meet critical requirements suffice, e.g. with regard to the uniform viscosity, the color, the odor, the stability, the Fiber to metal lubricity, fiber to fiber lubricity, anti-static effect and the washability. Chemically speaking, reel oils are carefully controlled blends of a mineral oil and at least one emulsifier, and they can include other additives such as fiber-holding and antistatic Means included.

For many years, yarn converters have had problems with the bobbin oil being thrown off during the Had yarn processing. Throwing off the spool oil is not just a waste, it is the thrown-off oil also poses safety hazards, e.g. slippery floors in the vicinity of the coil machines and respiratory problems and skin irritation when the ejected droplets are dispersed into a fine mist covering the entire area Contaminated work environment. With regard to the throwing off of oil, there are already various mechanical ones Solutions have been proposed, e.g., corrugated floors

609821/0988

and baffles on the coil machines. Of these mechanical solutions, however, have not yet been particularly effective. The best solution has always been To mop the area around the reel machine and to warn the staff to be careful to be. While these efforts have had limited success, manufacturing has of high-speed yarn the amounts of increased oil thrown off in the vicinity of the coil machines and the formation of mist in the atmosphere has thereby been increased. Furthermore, new official regulations for textile factories have been issued, which require additional measures to be taken to avoid unsafe floors. These new regulations have led to a pronounced need for an improvement in the spool oils, thus the spinning off of the oil in the vicinity of the bobbin machine during yarn processing is reduced will.

The present invention now relates to an improved bobbin oil for yarns or threads by means of which the spinning off of the oil is reduced during yarn processing. The improved coil oil is made in the way that one has a polybutene with a molecular weight of about 1200 to about 120,000 of a coil oil mixture adds, which contains a mineral oil and at least one emulsifier.

The improved bobbin oil can be prepared by using an effective amount of one or more the following polybutenes of a coil oil mixture

—5—

adds, which contains a mineral oil and at least one emulsifier. The amount of polybutene used can vary according to the proportion of mineral oil and emulsifier that are present in the coil oil mixture. For example, the improved bobbin oil can be about 0.05 to about 8.00 parts by weight of polybutene, with amounts of polybutene from about 0.10 to about 4.00 parts by weight to be favoured. It can contain about 5 to about 30 parts by weight of emulsifier, preferably about 10 to about Parts by weight, and about 70 to about 95 parts by weight of mineral oil. The above polybutene concentrations are based on 100% active polymer.

Polybutenes useful in the invention are commercially available under a variety of names. These polybutenes can be prepared by taking isobutylene at low temperatures (about -70 C) under Polymerized using Friedel-Craft catalysts. A solvent was used and the monomer to solvent ratio is used to regulate the molecular weight. The molecular weights can range from about 1200 to about 120,000. See R.M. Thomas, J.C. Zimmer, L.B. Turner, CB. Rosen and P.K. Frolich, "Ind. Eng. Chem.", Volume 32, pp 299-304 (1940). In generic terms, all of these products are known as polybutenes. Although they are essentially derived from isobutene, since they are technically produced from isobutene, the varying Contains percentages of n-butenes. Commercially available products are e.g. Indopol Polybutene H-300 and H-1900 with a molecular weight of 1200 and 2300 respectively and Paratac 504, formerly known as ECA 5040,

"The emulsifier can be any soluble anionic or nonionic surfactant having a suitable HLB number. The oil-soluble emulsifier can be a mixture of one or more surfactants that form a compatible formulation with the mineral oil. Suitable anionic surfactants are for example, saturated and unsaturated fatty acids. Suitable non-ionic emulsifiers are, like, for example, ethoxylated alcohols, ethoxylated saturated or unsaturated fatty acids, ethoxylated alkyl phenols and the like. also, oil-soluble polyethylene glycol ether obtained by reaction of a linear secondary C ^ ₁ ^ ₁ --Alkoholen with about 3 to 9 Moles of ethylene oxide can be used, as can oil-soluble mixtures obtained by mixing these ethers. Likewise, oil-soluble polyethylene glycol ethers of oxo-alcohols having the same carbon number and ethylene oxide contents as the linear secondary alcohols and oil-soluble mixtures of ethers can be used These oxo alcohols are used. It may be necessary to use mixtures of emulsifiers in order to obtain preparations that are compatible with the mineral oil. If necessary, a coupling agent such as water, butyl alcohol or the monobutyl ether of ethylene glycol can be used. the
