Definitions

• 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.
• the field of textile fibre treatment uses compositions for improving their manipulation and processing.
• 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.
• Auxiliary spinning compositions generally provide lubrication, and therefore reduce the friction between the fibres and between the filaments and the guide elements of spinning machines. Additionally, these auxiliary spinning compositions prevent the formation of electrostatic charges and confer a slight cohesion between adjacent fibres.
• fibre finishing compositions should be thermally stable and not corrosive, must be easily applied and removed from the fibres and must be physiologically compatible, as well as providing wetting properties to the fibres and being soluble or emulsionable in water.
• fibre-finishing compositions include lubricating agents as well as emulsifiers, antistatic agents, wetting agents, antioxidants, biocides ' , corrosion inhibition agents and/or pH regulation agents.
• Auxiliary spinning compositions are generally applied by contacting the fibres or yarns and the fibre finishing compositions comprising a solution or emulsion that includes at least one lubricant agent. These compositions can be sprayed or directly applied on the fibres or yarns.
• auxiliary spinning compositions are synthetic sterols, sorbitan esters, silicones, polyethers, esters of phosphoric acid, quaternised fatty amines, fatty acid alkanolamines, ethoxylated fatty acids, ethercarboxylate esters, and block polymers of ethylene oxide and propylene oxide or the like.

• Examples of fibres of chemical origin are:
• fibres of synthetic origin are, acetate and rayon, which are of cellulosic origin.
• fibres of natural origin are:
• the textile fibre on which the lubricant compositions containing ethercarboxylates are applied is a fibre of chemical origin of synthetic type.
• the coefficients were determined using a Rothschild F-Meter model R- 1188.
• the input tension was set at 0.15 N.
• the friction material used to determine the fibre/ceramic dynamic friction coefficient was a circular ceramic part.

• Lubricants described in Table 1 were applied on a continuous multifilament polyester fibre (150/30), in a concentration of 0.5% by weight (active product over fibres weight).
• polyester fibre Prior to this application the polyester fibre was scoured to eliminate any traces of impurities that it may contain.
• the dynamic friction coefficients fibre/fibre (F/F) and the "stick-slip” (S-S) values obtained with the lubricants according to the present invention show that, in general, the use of these lubricants confers an improved cohesion between fibres (higher stick-slip) when they are compared to lubricants corresponding to comparative examples 1-3.
• too high stick-slip values can however have a negative influence in the softness of the fibre, since a "cracant" feeling is then conferred to the fibre.
• better hand properties can be expected for the lubricants according to the present invention than for those corresponding to the comparative examples 4 and 5.
