Description

(54) Preparations for synthetic yarns, yarns, cables, cables and other fibrous formations.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a preparation composition for synthetic yarns, yarns, cables, cables and other fibrous formations which are applied to the fibrous materials during spinning or shaping or both in the form of aqueous dispersions in both operations. non-woven fiber during its cutting and shaping as well as its further textile processing.

The production of melt fibers for textile or technical purposes requires the use of suitable preparations which are necessary for the actual production process, for the spinning operation by upsetting, false twist, hot air flow or structural bending, as well as for processing in the twisting, knitting, tufting, weaving and any other operations.

On the synthetic fiber premixes, we put a stop on good lubricity as well as the ability to promote the formation of a uniform fiber formation, the desired degree of softening of the formed fibers, the protective function against mechanical damage during processing, manifested in sufficient fiber cohesion in the formation, on the antistatic effect, on thermostability in thermal cutting and molding, on the optimal friction properties in the fiber-metal, fiber-fiber, and fiber-sintercorundum system. From the ecological point of view, the good biodegradability of the preparation used is important.

The silicone preparations currently used, for example containing dimethyl silicone oil, respectively. preparation mixtures according to MS. AO 185 368 does not guarantee sufficient cohesiveness of the unsupported fiber for high speed processing. The organic component in them is poorly resistant to oxidation by air and microorganisms, while their silicone component is very difficult to degrade microbiologically. The availability of the silicone component of said preparations is problematic for economic reasons.

Podra pat. U.S. Pat. No. 852,612, fiber materials are treated in aqueous solutions of polyglycol addition products. This formulation is said to be preferred for polyesters.

According to the patent CH 538 554, it is recommended for synthetic fibers that the preparation comprises the aminosol of the alpha-sulfo fatty acid ester and the fatty acid ester.

Podfa pat. prihl. DE 2 447 410 for the preparation of staple fibers is a suitable condensation product of a fatty acid with an amine, while according to U.S. Pat. pat. 151 973 for the staple fiber spinning, it is proposed to use oreparation based on alkanoaminoalkylphenolpolyethylene glycol phosphate.

All of the above-mentioned preparation mixtures and compositions are easily washable, which is a major drawback.

A lubricant based on polyoxyalkylene glycol esters and dibasic acid mixtures is known from U.S. Pat. U.S. Pat. No. 3,925,589, while DE 2 446 542 proposes oil preparations based on mineral oils.

Said preparations do not meet the demands now made on mineral oil-based preparations.

These drawbacks of the preparations eliminate the preparation mixtures in the form of 1 to 20 wt. emulsions in water intended for synthetic fibers, yarns, yarns, mitts, cords and the like in accordance with the present invention, wherein the active ingredient is a mixture comprising:

- 10 to 90 wt. of component A, which is an alkylphenyl polyglycol ether phosphate in which the alkyl is a 6-16C aliphatic hydrocarbon radical containing from 1 to 20 moles of propylene oxide-ethylene oxide copolymer by rel mol. weight 900 to 2000, per mole of alkyl aryl polyglycol ether phosphate.

- 1 to 90 wt. component B, consisting of a mixture of:

up to 85 wt. % sulfonated vegetable oil, such as palm, soybean, castor oil, up to 85 wt. natural oil, such as castor oil, sunflower oil, soybean oil, tall oil, ethoxylated with 3-12 moles of ethylene oxide per mole of oil, up to 85 wt. the condensation product of an aliphatic fatty acid having from 8 to 20 Ca1, 1 mole per mole of the acid with mono- or trialkylolamine, wherein the alkyl in the alkylol is aryl or propyl. Spinning preparation, resp. the molding and final preparation composition according to the invention guarantees a content of 0.2 wt. The active substances on the fiber have good cohesiveness and high quality construction of unwound fiber, very good course of the forming and forming process and high operational reliability even at high processing speeds. The preparation emulsions are stable and oxidation resistant in contact with air, which guarantees the uniformity of the surface treatment of the fibrous materials. Both components of the preparation mixture are microbiologically degradable and meet hygienic requirements. Accordingly, both components for preparing emulsions are both easily accessible and economically advantageous.

Example 1.

In the manufacture of an air-shaped polypropylene cable having a fineness of 26.7 dtex and a total fineness of 2650 dtex, 8 wt. aqueous emulsion of the following active ingredient composition:

% wt. of component A, which is nonylphenyl polyglycol ether phosphate containing 10 moles of propylene oxide-ethylene oxide copolymer and rel. mole weight 1100 and wt. Component B consisting of:

% wt. % sulfonated olive oil,% wt. of ethoxylated castor oil containing 4 moles of ethylene oxide per mole of oil and 60 wt. of the condensation product of ethynolamine with ricinooleic acid in mol. 1: 1 ratio.

An emulsion was prepared by mixing the ingredients with water at 40 ° C for 30 minutes.

The cable spun and treated with this preparation mixture showed very good operational reliability during the spinning, winding, scouring, forming and twisting operations. The shaping was uniform and the product had good physical-mechanical and dynamic properties.

For comparison, an attempt was made with the preparation according to MS. AO 185 368 at a concentration of 8% by weight. of active substances.
