| titleOfInvention | Improvements in the treatment of keratinous fibre fabrics |
| abstract | A keratinous fibre containing fabrics is pressed by a process comprising treating the fabric with a reducing agent capable of splitting the cystine linkages of the keratinous fibres and then paper pressing the fabric under heat and pressure between layers of paper. The reducing agent may be an alkanolamine sulphite containing up to 8 carbon atoms in the alkyl chain, zinc or sodium formaldehyde sulphoxylate, sodium potassium borohydride, sodium ride, sodium potassium borohydride, sodium or potassium bisulphite, sulphite, metabisulphite or hydrosulphite, ammonium bisulphite, sodium sulphide, hydrosulphide, hypophosphite, thiosulphate or dithionate, titanouschloride, sulphurous acid, thioglycollic acid and its water soluble salts, hydrogen sulphite potassium hydrosulphide, ethyl or butyl mercaptan, b -mercapto ethanol and mixtures thereof. The reducing agent may be applied to the fabric as an aqueous solution containing 0.01-20% by weight of the reducing agent by spraying, padding, squeezing, immersion or wetting with blankets saturated with the solution. The fabric may then be rolled and stored or partially air dried and stored prior to paper pressing. It may then be adjusted to a moisture content of 20-40% moisture regain and subjected to paper pressing for from 30 seconds to 10 hours at a temperature of 125 DEG -300 DEG F and pressure of 100-500 p.s.i. The treating solution may also contain a swelling agent, e.g. urea, guanidine hydrochloride, formamide, N,N-dimethyl formamide, acetamide, thiourea, phenol or lithium chloride, bromide or iodide, or a poly hydroxy compound containing more than one hydroxy group and having a molecular weight of not more than 4000, e.g. ethylene glycol, trimethylene glycol, tetramethyleneglycol, pentamethyleneglycol, hexamethyleneglycol, decamethyleneglycol, 1,2 propyleneglycol, dipropyleneglycol, 1,3 butyleneglycol, diethyleneglycol, polyethyeneglycol, polypropyleneglycol, glycerine, diethylglycerol, trimethylol ethane, trimethylol butane or trishydroxymethyl amino methane. Fabrics comprising keratinous fibres, e.g. sheep wool, lamb wool, mohair, alpaca, camel hair, cash-mere, vicuna, llama or angora wool, alone or in admixture with other fibres, e.g. polyacrylonitrile fibres, may be treated. Fabrics having a high lustre and soft handle are produced. |
