Description
Patented Nov. 11, 1930 UNITED STATES Para NI OFFICE-- THEODOOR KOCH, or nnnnnnnfirnnnnnnbs FROM vIscosE No Drawing. Application filed October 3, 1927, Serial No.. 223,831, and in theNetherlands February Although the high luster of artificial silk was originally considered to be one of its principal properties, for the past few years it has been proposed to bring the luster of this pro-duct in accordance with that of natural silk, and attempts have also been made to obtain a dull product which could eventually be used as a substitute for W001.
For instance the preparation of artificial silk, with a reduced luster, from viscose is already well-known. This is done by spinning immatured or only feebly matured viscose in a spinning-bath which consists of acidulated salt solutions as prevailing in nature. Another method for obtaining the same result consists of adding metal compounds to the viscose, such as calcium-hydroxide and sodium-aluminate, which cause insoluble precipitates in the thread with the constituents of the spinning-bath (sulphuric acid, monosodium-phosphate.) To obtain wool substitute with reduced luster it has already been proposed to dispense with both the ripenings and to spin immediately after zanthogenization in a spinning bath of a dilutemineral acid.
Besides some drawbacks met with in the technical application, these processes have a further disadvantage that the products obtained in this way may hardly take the name of artificial silk, especially with regard to the feeling, tensile strength and elongation.
In contradistinction herewith, the new I products according to my invention, have the advantage that in view of feeling, drying and other properties, they may be compared with ordinary artificial silk or may be even better quality, not having the very dazzling luster of ordinary artificial silk, but more the quiet luster of natural silk. According to my invention however, it is also possible to obtain entirely dull products without any luster whatever, if :for any reasons, they may be re-. quired.
The new composition of matter according to my invention comprises viscose containing chlorobenzene or a mixture of monoand dichlorobenzene.
By the term immiscible is intended those substances which can only be incorporated inastateof fine division in the viscose to form an emulsion by intense agitation as distinct from substances which are I normally solublein'theviscose orreadily form a colloidal solution therein.
In order'to obtain a product of the desired properties, it is of considerable importance that the additions are very finely mixed with the viscose; according to my invention, additions or mixtures ofadditions are used, the specific weight of which must correspond practically with that of the viscose to be worked up.
Example 1 To normal viscose one per cent of monochlorobenzene is added and this substance is divided very finely in the spinning liquid by intensified agitation. The viscose thus prepared is spun in the usual way at a ripeness of about 9.5 Hottenroth at about 4045 C. in a spinning bath containing 12% of magnesium sulphate, 12% sodium-sulphate, and 10% sulphuric acid. Thereupon is the product finished, and the addition evaporates 011 drying the spun material. A thread of good physical properties is obtained, possessing, however, a reduced luster.
The amount ofthe reduction of luster depends upon the proportion of the addition.
Example 2 One per cent. of a mixture of monoand dichloro-benzene of a specific Weight corresponding with that of the viscose of 1.12 is added and thereupon emulsified. At the usual ripening temperature no separation of the mixture takes place, and also no separation after a Week notwithstanding the usual intermediate filtrations.
The spinning liquid is spun at the ripeness and in a spinning bath as described in Example l, whereupon the silk is finished and dried in the normal way. A product isobtained of very much reduced luster of good elongation and tensile strength.
I claim:-
1. As a new composition of matter to be spun into artificial silk, viscose containing chlorobenzene.
This is obtained if, for instance,
2. As a new composition of matter to be spun into artificial silk, viscose containing a mixture of monoand di-chlorobenzene.
V3. Asa new composition of matter to be spun into artificial silk, viscose to which has 7 been added amixture of mono-' and di-chlorobenzene in such relative p'roportionsthat the specific Weight of the addition is practically in accordance With that of the viscose to be ks p-J I 4. As a newcomposition of matter tobe spun into artificial silk, viscose to Which has been addedapproximately li% of aomixturej,
of monoand di-chlorobenzene in such rela-; tive proportions that the specific Weight of the addition is practically in accordance with V e that of the viscose to be worked up; i In testimony whereof I affix my signature.
