Description

Patented May 5, 1931 UNITED STATES HANS FRIEDIAENDER, or BERLIN, GERMANY TREATMENT OF FIBROUS MATERIAL No Drawing. Application filed April 9, 1928, Serial No. 268,798, and in Germany May 17 1927.
This invention relates to the treatment of artificial fibrous material for instance artificial silk, including loose fibres adapted for textile purposes and products formed therefrom.
According tothe present invention artificial fibrous material .(for instance artificial silk) is treated with emulsions of hard waxes to which are added agents adapted to secure the precipitation of the wax upon the fibres.
The invention may be carriedinto effect in such manner that products are obtained containing only a relatively small proportion of hard waxes in relation to the fibre. The proportion may, for instance, amount to not more than 1 to 10 per cent. of the dry weight of the fibre.
The invention extends, as above indicated,
also to the treatment of loose fibres, for in- Preferably in accordance with the inven-' tion an emulsion of Montan wax is used as the hard wax and with advantage Montan wax which has in order to refine and harden it, been first fused and heated to a temperature of 230 to 250 C. while air is blown therethrough is employed.
Optionally in accordance with the invention the emulsions may contain oils and similar materials singly or in combination one with the other.-
In the treatment of artificial fibres the hard waxes may be and are preferably employed in association with known sizing agents for instance resin.
The following particulars are given by way of example to illustrate suitable methods of carrying the invention into efiect Emample 1 An emulsion being formed from Montan wax hardened and refined by heat treatment and resin in' the proportion of 84 parts to 16 parts is used for treatment of artificial silk threads or hanks by dipping same into the emulsion. Alum or aluminium sulphate is added to the artificial fibrous material in order to precipitate the wax and the product stance cotton, linen, silk, wool or artificial.
is treated in known manner for the formatlon of artificial fibrous articles. These may be satined by treatment between hot rollers.
Ewample 2 Montain wax in the artificial silk by means of a precipitant. The emulsion employed .may contain per cent. of hardened Montan wax, 10 per cent. of oil or fat and 10 percent. of resin.
Ema/mph 3 Artificial silk fibres are treated with an emulsified mixture obtained by emulsifying hard wax and resin in the proportion of of the former to 15 of the latter. Precipitation is then effected by the employment of aluminium sulphate. The further treatment is effected in known manner and the proportions of the additions made amount to about 10 per cent. of the dry weight of the fibre.
Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. The process of producing impregnated artificial fibrous materials, which comprises effecting the precipitation in and on theartificial fibre'of hard wax.
2. The process of producing impregnated artificial fibrous materials, which comprises effecting the precipitation in and on the artificial fibre of hard wax from an emulsion thereof.
3. The process of producing impregnated artificial fibrous materials which comprises effecting the precipitation in .and on preformed artificial fibre of hard wax from an emulsion thereof.
4. The process of producing impregnated artificial fibrous materials, which comprises' effecting the precipitation in and on artificial silk of hard wax from an emulsion thereof.
5. The process of producing impregnated artificial fibrous material which comprises effecting the precipitation in and on the fibre of Montan wax.
6. The process of producing. impregnated artificial fibrous materials which comprises effecting the precipitation in and on the fibre of hardened Montan wax.
7. The process of producing impregnated artificial fibrous materials which comprises efiecting the precipitation in and on the fibre of hardened Montan-wax from an emulsion of Montan waxwhich has been fused and heated to a temperature of 230250 C., while air is blown therethrough.
8. The process of producing impregnated artificial fibrous materials which comprises efl'ecting the precipitation in and on the fibre of hard wax from an emulsion thereof containing materials adapted to modify the properties of the hard wax.
go 9. The rocess of producing impregnated artificial br-ous materials which comprises effecting the precipitation in and on the fibre. of hard wax from an emulsion thereof con-' taining' oil.
10. The process of producing impregnated artificial fibrous materials which comprises effecting the precipitation in and on the fibre of hardened Montan wax from an emulsion of Montan wax which has been first fused I0 and heated to a temperature of 230250 0.,
while air is blown therethrough, and which contains a roportion of oil.
' 11. Arti cial fibrous material consisting of a cellulose derivative containing hard wax 85 gisseminated throughout the substance of the 12. Artificial fibrous material consisting of a cellulose derivative containing Montan wax disseminated throughout the substance of 4 the fibre.
13. Artificial fibrous material consisting of a cellulose derivative containing hardened Montan wax disseminated throughout the substance of the fibre.
14. Artificial fibrous material consisting of a cellulose derivative containing Montan wax which has been first fused and heated to a temperature of 230250 0., while air is blown therethrough, disseminated throughout the substance of the fibre.
15. Artificial fibrous material consisting of a cellulose derivative containing hard wax and materials adapted to modify the properties of the hard wax disseminated through- 55 out the substance of the fibre.
16. Artificial fibrous material consisting of a cellulose derivative containing hard wax and oil disseminated throughout the substance of the fibre. 80 In testimony whereof I have signed my name to this s ecificaiton.
