Benefits of technology

"The patent text describes the use of ethercarboxylates to lubricate textile fibers, specifically spinning fibers. The technical effect of this invention is the development of a process for lubricating textile fibers."

Problems solved by technology

As can be easily seen, a single substance can hardly provide these numerous requirements.
However, the prior art does not describe nor suggest the use of ethercarboxylates for the lubrication of textile fibres.

Lubrication of Textile Fibres

[0065] The fibre / ceramic (F / K) and fibre / fibre (F / F) dynamic coefficients of friction and the “stick-slip” (S-S) were obtained for the lubricants described in Table 1. The values of these parameters are shown in Table 2.

[0066] Table 1 shows lubricants according to the present invention (LF.1-LF.10) and comparative examples.

[0067] The coefficients were determined using a Rothschild F-Meter model R-1188. The input tension was set at 0.15 N.

[0068] The friction material used to determine the fibre / ceramic dynamic friction coefficient was a circular ceramic part. In addition, a speed of 50, 100 and 200 mm / min was used with a contact angle of 180°.

[0069] When determining the fibre / fibre (F / F) dynamic coefficient of friction the speed was set at 1 mm / min and the contact angle at 360°.

[0070] The “stick-slip” (S-S), a characteristic phenomenon of low-speed friction, was calculated as the difference between the average maximum value and the average minimum v...

Abstract

The present invention discloses the use of ethercarboxylates for lubricating textile fibres, preferably spinning fibres. These ethercarboxylates have the general formula (I) R—(OCH2CH2)n—O—CH2COOX  (I) where: R represents a C6-C22 aliphatic hydrocarbon chain, saturated or unsaturated, linear or branched, n is a number between 0.3 and 50, X is hydrogen, an alkali metal, an ammonium cation, an alkanolammonium cation or a C6-C22 alkylammonium cation. In addition, the present invention provides a process for lubricating textile fibres that consist of placing in contact these textile fibres with ethercarboxylates of general formula (I).

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of International Application PCT / EP2003 / 014365 filed on Dec. 17, 2003, pending at the time of filing of this continuation application, the contents of which are herein wholly incorporated by reference.FIELD OF THE ART [0002] The present invention relates to the field of textile fibre treatment, specifically to the use of auxiliary spinning composition or finishing compositions, and particularly to the use of ethercarboxylates for lubricating textile fibres, such as spinning fibres. PRIOR ART [0003] The field of textile fibre treatment uses compositions for improving their manipulation and processing. [0004] These compositions, known as auxiliary spinning compositions or finishing compositions, allow, on one hand, to manufacture the textile fibres and, on another, to facilitate the subsequent spinning and weaving processes used to obtain the final textile products. [0005] Auxiliary spinning compositions ...
