Patented Dec. 9, 1930 UNITED STATES PATENT OFFICE THEODOOR KOCH, OF ARNHEM, NETHERLANDS, ASSIGNOR TO ALGEMEENE KUNSTZIJDE UNIE NAAMLOOZE VENNOOTSCHAP, OF ARNHEM, NETHERLANDS PROCESS OF PREPARING ARTIFICIAL TEXTILE PRODUCT WITH REDUCED LUSTER No Drawing. Application filed October 3, 1927, Serial No. 223,833, and in the Netherlands April 7, 1927.
In my patent application Ser. No. 223,831, filed Oct. 3, 1927, I have described a process for preparing artificial textile products with reduced luster, from viscose, according to which chlorobenzene or a mixture of monoand di-chlorobenzene is added to theviscose. According to my invention the said substances are added preferably in such proportions that the specific weight of the additions practically corresponds with that of th viscose to be worked up.
According to my above mentioned process an artificial silk of very good properties, with reduced luster, is indeed obtained. In practice, however, diificulties are encountered and especially if artificial threads below six denier are to be prepared according to the process described in the above patent.
After laborious researches it appeared that the cause of these less favourable results must be seen in the insufficient division of the additions, and that the large number of spinning faults occurring during the spinning of fine denier silk must be ascribed thereto. According to my invention it is possible to prepare silk with reduced luster and a low denier number per elemental fibre with the aid of my above mentioned process.
Further it has appeared that a special proportion exists between the largest allowable diameter of the particles and the denier number per elemental fibre of the silk to be spun.
According to my invention the dimension of the particles of the additions is preferably chosen smaller as finer threads are to be spun, and this in agreement with the equation 40 in which D is the denier number of theelemental thread, a the largest allowable dlamieter in microns of the parts, and c the constant, which for normal viscose amounts to about the dimension of the parts for 0=% is given by the following table allowable diameter of the additions is 6.9. From the equation D 0 (a a) it follows that a fromwhiclrit follows that c= I r In this way the constant c'may be'determined forany viscose, which, as has already been observed,is about Afor a normal spinning viscose. v
If it is desired to determine for a Viscose, so
of which the constant is c, the largest allowablediameter of the additions for a different denier per elemental fibre, one proceeds as follows If a denier of 3 is to be spun, the equation 1s D c(a +a) =9=%(a +a), from which it follows that After it was found that in general for a low denier number the diameter of the added particles should be smaller, it was not to be foreseen that the'largest permissible diameter of the particles would have aspecial function depending upon the fineness of the silk, and that the denier number would be a double function of the diameter.
It is clear that one is enabled by this rule to pie-determine for any desired fineness of the silk which has the largest allowable diameter of the added oarticles; so that by applying the process according to my invention, it is possible to spin very fine .deniers and to obtain a product of reduced luster.
It is obvious that the usual measures for spinning low denier silk have also a. favourable influence in the process according to my invention. Also, as can be expected, the well-known favourable influence of a small amount of zinc sulphate in the spinning bath is perceptible in this process.
I claim:
1. In a process of preparing a solution of viscose containing chlorobenzene for spinning into artificial silk threads with a reduced luster and of a size below 6 denier, the step of emulsifying the solution to such an extent as to form particles of chlorobenzone of a diameter which is a function of the denier number of the threads which are to be spun, which diameter varies according to the formula :D =c(a a), in which D the denier number, a the largest allowable diameter of the particles in microns, and c a corn stant, which for normal viscose is about twothirds.
2. In a process of preparing a solution of viscose containing a mixture of mono and di-chlorobenzene for spinning into artificial silk threads with a reduced luster and of a size below 6 denier, the step of emulsifying the solution to such an extent as to form particles of monoand di-chlorobenzene of a diameter which is a function of the denier number of the threads which are to be spun, which diameter varies according to the formula :D=c(a +a), in which I) is the denier number, a the largest allowable diameter of the particles in microns, and 0 a constant, which for normal viscose is about twothirds.
3. In a process of preparing a solution of viscose containing a mixture of monoand dichlorobenzene for spinning into artificial silk threads with a reduced luster and of a size below 6 denier, the relative proportions of which mixture are such that the specific weight of the mixture of monoand dichlorobenzene practically corresponds with that of the viscose, the step of emulsifying the solution to such an extent as to form particles of monoand di-chlorobenzene of a diameter which is a function of the denier number of the threads which are to be spun, which diameter varies according to the formula :D 0(a +a), in which D is the denier number, a the largest allowable diameter of the particles in microns, and c a constant which for normal viscose is about twothirds.
4. In a process of preparing a solution of viscose containing approximately 1% oil a mixture of monoand di-chlorobenzene for spinning into artificial silk threads with a reduced luster and of a size below 6 denier, the relative proportions of which mixture are such that :the specific weight of the mixture of monoand di-chlorobenzene practically corresponds with that of the viscose, the step of emulsifying the solution to such an extent as to form particles of monoand di-chlorobenzene o-f:a diameter which is a function of the denier number of the threads which are to be spun, which diameter varies according to the formula :D =c(a +0), in which I) is the denier number, a the largest allowable diameter of the particles in microns, and c a constant, which for normal viscose is about two-thirds.
In testimony whereof I affix my signature.
THEODOOR KOCH.
