Definitions

• An anti-felting finish is imparted to animal fibres by means of synthetic resins, by applying aliphatic and/or [30] Foreign Application Priority Data cycloaliphatic diamines and/or polyamines in aqueous May 14, 1970 Germany 2023671 Solution to the fibre and a Second aqufious solution is used to carry out an already known anti-felting 5 CL N 117/76 T, 117/1395 A, 117/141, treatment by impregnating the fibre with the solution 117/161 KP of a possibly bufiered salt of a polymer base which is [51] Int.
• This invention relates to a process for imparting an anti-felting finish to animal fibres, which is suitable more particularly for finishing fabrics in web form.
• the object of the invention therefore is to find a finishing process whereby webs of woven or knitted animal-fibre interlinings can be finished on conventional finishing plants and from an aqueous bath, with mini-. mum hardening of the touch or feel, so as reliably to prevent any felting or migration of the animal fibres during the wearing and conventional cleaning of the garments provided with the interlining fixed thereto.
• aliphatic or cycloaliphatic diamines or polyamines in aqueous solution are applied to the fibres and then a second aqueous solution is used for an already known anti-felting treatment by impregnating the fibres with the solution of a possibly buffered salt of a polymer base which is deposited on the fibres during the subsequent action of heat.
• All water-soluble diamines and polyamines are suitable, for example ethylene diamine, hexamethylene diamine, dicyclohexyl diamine, diethylene triamine, dipropylene triamine, triethylene tetramine.
• ethylene diamine hexamethylene diamine, dicyclohexyl diamine, diethylene triamine, dipropylene triamine, triethylene tetramine.
• amine calculated as NH and NH group
• the quantity of amine can be increased to about 20 mg of amine per gram of animal fibre.
• Treatment of the fibre may be carried out, for example, on the yarn in an aqueous bath of the amine heated to about C, a treatment time of about 10 to 30 minutes being sufficient.
• the finishing process is carried out on the finished woven or knitted web material by means of a padding machine.
• the material is dried and condensed.
• the drying temperature should not exceed 160C. A temperature action of about 2 minutes is sufficient at C.
• the impregnation with the solution of a salt of a polymer base which is deposited in the form of the free base on the fibre with the application of heat, possibly with the addition of a buffer substance, is carried out in another operation.
• a salt of a polymer base which is deposited in the form of the free base on the fibre with the application of heat, possibly with the addition of a buffer substance.
• anti-felting agents for example, are sulphonium halides which are linked to polyurethane radicals and which are particularly suitable for the proposed combined application with amines and which are therefore preferred.
• Other usable salts of polymer bases are appropriately selected watersoluble salts of polyamidoamines, whose free amino groups can react with organic or inorganic acids to form salts.
• methylol compounds, formaldehyde, formaldehyde liberating compounds such as urotropin, and other finishing agents based on aqueous solutions and dispersions for example reactive (meth)-acrylate dispersions, polyethylene dispersions, urea resins, melamine resins and so on, may be added to the solutions of salts of polymer bases.
• EXAMPLE 1 3 piecesof a loose woven interlining consisting of a wool warp and a camel hair weft having a weight of 1 l0 gram per square metre were degreased on a conventional finishing machine, squeezed out and immediately finished, in the wet state, on a padding machine using an aqueous solution containing 0 gram, 20 gram and 40 g/l of hexamethylene diamine. The absorption of the The bath absorption was 100 gram per 100 gram of fabric. After drying, the material was condensed for 2 minutes at 140C. Ternary 6, 6/6, 12 copolyamide was then applied in spots, the application being 20 gram per square metre.
• EXAMPLE 2 Degrcased sheeps wool and camel hair yarns wound on cheeses were rinsed for 25 minutes with an aqueous solution of dipropylene triamine which had been heated to 95C and which contained 0 gram, 0.5 gram and 1.5 gram of dipropylene triamine per 100 gram of animal fibre. After this treatment, the cheeses were washed with cold water, centrifuged and dried at 120C. The identically treated sheep's wool and camel hair yarns were woven into three interlining fabrics of a weight of about 1 10 gram per metre and then padded with the solution of polyurethane sulphonium halide from Example 1 and treated further.
• the proposed combined treatment is not limited just to animal interlinings.
• any animal fibre for any purpose necessitating anti-feltingtreatment can be treated by the process.
• a process for imparting an antifelting finish to animal fibres which comprises a first step of applying to the fibers at least one compound selected from the group consisting of aliphatic and cycloaliphatic diamines and polyarnines from an aqueous solution thereof and a second step of applying an aqueous solution of a salt of a synthetic resin base to the resulting fibers and heating the fibers to condense the synthetic resin base from the applied solution onto the fibers said synthetic resin base salt being selected from the group consisting of polyurethane sulphonium halides and water-soluble polyamidoamine salts of organic or inorganic acids.
• a process according to claim 1 wherein the compound selected from the group consisting of aliphatic and cycloaliphatic diamines and polyarnines is at least one compound selected from the group consisting of ethylene diamine, hexamethylene diamine, diethylene triamine, dipropylene triamine, dicyclohexyl diamine and triethylene tetramine.
• a process according to claim l-for imparting an anti-felting finish to animal fibres selected from the group consisting of wool and camel hair which comprises a first step of applying to the fibres at least one compound selected from the group consisting of hexamethylenediamine and dipropylene triamine from an aqueous solution thereof, and a second step of applying an aqueous solution of polyurethane sulphonium halide to the resulting fibres and heating the fibres to condense the free base polymer from the applied solution onto the fibres.
