Patented Dec. 10, 1935 METHOD OF INCREASING TENSILE reor- ERTIES or VISCOSE' apron James Willard Humphrey, Claymont, Del., and John Watson Pedlow, Chester, Pa., assignors to The Viscose Company, Marcus Hook, Pat, a corporation of Pennsylvania No Drawing. Application November 12. 1934, Serial No. 752,784
13 Claims. (Cl. 1106-40) This application is in part a continuation or our copend-ing application of the same title, Serial No. 657,464, filed February 18th, 1933.
The object of our invention is to produce viscose rayon having increased tensile properties.
We have discovered that by adding to the viscose solution organic liquids which do not substantially remain with the finished rayon, but instead are almost entirely lost during the spinning operation when spun in the usual manner, we can produce viscose rayon having greater tensile strength than normal yarn, and also having a marked increase in softness, but without pronounced difierence in dye absorbing capacity or general appearance.
Generically, in carrying out our invention, we add to the viscose solution one or more of a group of materials which we have discovered to be operative for this purpose, and then carry out the spinning operation in the usual manner. This group of materials, all of which are operative for our purpose, consists in those aromatic derivatives of the aliphatic alcohols in which a hydrogen atom which is attached directly to a. carbon atom has been replaced by an aromatic group. In other words, the aromatic group has been substituted for a hydrogen atom other than that of the hydroxyl group of the alcohol.
As a sub-genus of the broad class of compounds disclosed above as being operative for our purpose, we preier the phenyl derivatives of the aliphatic alcohols, in which the phenyl or phenyl derivative replaces a hydrogen atom other than that of the hydroxyl group of the alcohol.
The viscose solution to which the material is added is normally a solution of cellulose xanthate in dilute alkali, the concentration of cellulose being from 7 to 8% and the sodium hydroxide from 6 to 8%. In spinning the solution with the material added thereto the same is pumped through a spinneret into a coagulating bath which generally contains around 8% sulphuric acid, 12% sodium sulphate and it may also contain from to 15% glucose and also .2 to 1.5% zinc sulphate. It is understood that the composition of the viscose solution and the composition of the coagulating bath as given above are merely by way of illustration of current plant practice and that the proper functioning of the material added according to the present invention to produce a stronger and softer yarn is by no means limited to such conditions.
The increase in tensile properties is in proportion to the amount of material added, and can be as high as 35% increase in wet strength,
increase in dry strength, and 20% increase in dry extensibility. With larger amounts of material added these strengths may be increased further, but for economical reasons we prefer to add the material in amount of 1% to 2% by weight on 5 the viscose solution, or approximately to 80% on the basis of the cellulose present in the viscose. The major portion of the material so added apparently does not remain with the finished yarn, but is almost entirely lost during the spinning operation. The added material largely disappears from the yarn during the spin ning operation and thus is positively removed from the extruded filament.
As representative and illustrative of the group of materials hereinbefore disclosed as operative for our purpose, the following specific members of the broad group are given by way of exam ple:
1. Anisyl alcohol, which may be considered as methyl alcohol in which a hydrogen has been replaced by a methoxy phenyl group;
2. Benzyl alcohol, which is methyl alcohol in which a hydrogen has been replaced by phenyl only; and
3. Phenyl ethyl alcohol, which is ethyl alcohol in which a hydrogen has been replaced by phenyl;
4. Paraclor benzyl alcohol, which is a methyl alcohol in which a hydrogen atom attached to the carbon atom has been replaced by the paraclor benzene group.
These examples have been selected because they are commercially available in suitable quantities and at economical prices, and not in derogation of the other members of the disclosed broad class or group.
It is not necessary to have the material soluble in the viscose solution. For example, 1 benzyl alcohol may be added to the viscose as an emulsion or as the sodium salt which is soluble in the viscose solution.
As a specific example of the process, viscose solution is prepared as usual, is filtered, aged, and then within 24 hours of the proper spinning time, 1 by weight of benzyl alcohol is thoroughly emulsified in the viscose solution at the proper spinning age and under normal spinning conditions this viscose is then spun, reeled, processed, etc. Tensile tests made on this yarn show that there is an increase in wet strength of approximately of dry strength approximately 5%, and of dry extensibility of approximately 15%.
What we claim is:
1. Method of increasing tensile properties of viscose rayon which comprises adding to the viscose solution an aromatic derivative of an aliphatic alcohol, the aromatic group replacing a hydrogen atom other than that of the hydroxyl group of the alcohol, the major portion of which does not remain with the extruded filament, but is almost entirely lost during the spinning operation, whereby viscose rayon'is produced having materially greater tensile properties than viscose rayon similarly spun without the addition and loss of any such material.
2. Method of increasing tensile properties of viscose rayon which comprises adding to the viscose solution a phenyl derivative 01. an aliphatic alcohol, the phenyl or phenyl derivative grouping replacing a hydrogen atom which is attached directly to a carbon atom whereby a solution is obtained which upon spinning produces viscose rayon'having materially greater tensile properties than viscose rayon similarly spun without theaddition of any such material.
.3. Method of increasing tensile properties of viscose rayon which comprises adding to the viscose solution a phenyl derivative of an allphatic alcohol, or the group consisting of anisyl, benzyl phenyl ethyl, and paraclor benzyl alcohols, whereby a solution is obtained which upon spinning produces viscose rayon having materially greater tensile properties than viscose rayon similarly spun without the addition of any such material.
