Definitions

• the present invention relates to a finish composition, particularly for polyolefine fibres. It relates also to a fiber finish process which uses the above mentioned composition.
• Thermosealing polypropylene fibres are widely used in the hygienic-sanitary field in the manufacture of calendered non-woven fabrics for coverstocks, overalls, monouse sheets.
• a marked hydrophobic characteristic is requested to the non-woven fabric: for example, it is requested to be possible to manufacture non-woven fabrics having a high barrier capacity towards aqueous liquids.
• the measure of the hydrophobic capacity is carried out on fiber staples measuring the "sinking time", that is the time necessary so that the staple, placed in water in a wide mesh basket, sinks under the liquid surface of a little tank filled with water (ASTM method D 1117-58).
• the polypropylene fiber in that wholly olefinic, is as such hydrophobic.
• the industrial processes for producing the fiber and for transfiorming it into finished manufactured product involve necessarily the addition, on the fiber surface, of surface active agents, slipping agents, antistatic agents, in the step of the process named finish.
• the presence of the agents substantially modifies the surface characteristics of the fiber and therefore the "sinking time" also.
• hydrophilic/hydrophobic degree of the fiber is, as a matter of fact, industrially adjusted by the use of specific surface active agents.
• the present state of the art is to finish the fiber with a mixture of silicone products, which give hydrophobic capacity and lubrication, and surface active antistatic agents, such as for example, esters such as alkyl phosphates, which give antistatic capacity without interferring with the hydrophobic degree.
• silicone compounds are used as release-agents.
• Object of the present invention is to provide a finish composition free of silicone additives, and which allows to solve the above mentioned problem relating to the insufficient adhesion without compromising in any way the hydrophobic capacity and the processability of the fiber.
• the finish composition comprises, in mixture or separated each from the other, a condensation product (A) of a fatty acid with a polyalkylenamine, quaternized with the condensation product of a chlorhydrin with polyethylene glycol, and a condensation product (B) of a hydrogenated fatty acid and an aminoalkylalkanolamine (also named hydroxyalkylenediamine), neutralized with an alpha-hydroxycarboxylic acid, added with a polyoxyethylated fatty alcohol.
• the component (B) alone shows better antistatic characteristics but not sufficient hydrophoby.
• components (A) and (B) are used in mixture each other, their weight ratio is preferably comprised between 35/65 and 60/40.
• the level or total concentration of finishing agents on the fiber is preferably comprised between 0.3 and 0.6% by weight, more preferably between 0.4 and 0.5% by weight.
• the fatty acid used in the condensation to obtain the component (A) is preferably a saturated C16-C20, more preferably stearic acid.
• the saturated fatty acid is preferably condensed with tetraethylpentamine.
• the chlorohydrin used to obtain the condensation product with polyethylene glycol able to act as crosslinking and quaternizing agent in the preparation of the component (A) is preferably bis-chlorohydrin ether.
• the condensation product between the polyethylene glycol and the chlorohydrin is present, in the component (A) in a small concentration preferably comprised between 0.5 and 5% by weight.
• the fatty acid used in the condensation reaction to obtain the component (B) is preferably a fatty acid obtained by hydrolysis of tallow, whereas the aminoalkylakanolamine is preferably aminoethylethanolamine.
• the alpha-hydroxycarboxylic acid used to neutralize the condensation product of the hydrogenated fatty acid with the aminoalkylalkanolamine is preferably selected from the group which consists of glycolic acid, mandelic acid, lactic acid, hydroxybutyric acid and mixtures thereof. More preferably glycolic acid is used.
• the polyoxyethylated fatty acid used in the preparation of the component (B) as emulsifier is preferably a fatty alcohol deriving from tallow, condensed with ethylene oxide; for each mol of fatty alcohol 15 mols of ethylene oxide are preferably used.
• the present invention has as object also a fiber finish process which compises the treatment of the fiber with the product (A) only as above defined in aqueous solution at a concentration preferably comprised between 5 and 30 g/l in such a way to leave on the fibres an active residue comprised between 0.005 and 0.05% by weight, and the subsequent treatment of the fiber with a mixture of the products (A) and (B) as above defined in a weight ratio (A)/(B) comprised between 30/70 and 60/40 and at a such concentration to leave on the fiber an active residue comprised between 0.1 and 0.8% by weight.
• a polypropylene fiber obtained by spinning on an industrial plant has been subjected to finish on a pilot plant.
• a product (A) obtained from the condensation of stearic acid with tetraethylenepentamine, with about 1% by weight of polyethylene bis-chlorohydrin as quaternizing and crosslinking agent has been applied.
• the concentration of the product (A) in aqueous bath was equal to 15 g/l, in such a way to leave an active residue on the fiber equal to 0.02% .
• a mixture of the product (A) and of a product (B) obtained from the condensation of fatty acids deriving from hydrogenated tallow with aminoethanolamine, neutralized with glycolic acid and alcohols deriving from tallow condensed with about 15 mols of ethylene oxide as emulsifier agent has been applied.
• the "sinking time" on the staple resulted about 24 hours; the processability of the fiber on textile machines for opening, carding and calendering has resulted good.
• the sinking time on the staple has resulted higher than 48 hours; the processability and adhesion of labels to the non-woven fabric were good.
• the sinking time on the staple has resulted higher than 48 hours; the processability acceptable (slight problems due to the static electricity at the highest working speeds).
