Description
Die gesponnene Kunstseide aus Celluloseacetat wird im allgemeinen durch Leimen für das Weben vorbereitet, wodurch die Fäden der natürlichen Rohseide mehr oder weniger ähnlich gemacht werden. Dieser Leim muß nach dem Verweben entfernt werden, bevor man zum Färben schreiten kann.The spun rayon from cellulose acetate is generally made by sizing for the weaving prepared, making the threads of natural raw silk more or less can be made similarly. This glue must be removed after weaving before one can proceed to dyeing.
Das Leimen geschieht auf mannigfache Weise; die Verfahren, die für das VerwebenGluing is done in a variety of ways; the procedures necessary for weaving
ίο am geeignetsten sind, also bevorzugt werden, sind diejenigen, bei denen der Leim nur schwer wieder entfernt werden kann. Es ist hierzu nötig, die Gewebe mit heißer Seife zu behandeln, was sehr schädlich ist; die Acetatfäden verlieren hierbei einen Teil ihrer Widerstandsfähigkeit und ihren Glanz, werden also matt.ίο are most suitable, i.e. preferred, are those where the glue is difficult to remove. It is this requires treating the fabric with hot soap, which is very harmful; the acetate threads lose part of their resilience and shine, so become frosted.
Die aus roher Naturseide und Acetatseide hergestellten Mischgewebe müssen ebenfalls vor dem Färben oder Bleichen zunächst energisch behandelt werden.The blended fabrics made from raw natural silk and acetate silk must also vigorously treated before dyeing or bleaching.
Zum Entbasten der Naturseide verwendet man ein sehr heißes Seifenbad, das von der Acetatseide nicht vertragen wird. Es ist also nötig, das Acetat gegen den verderblichen Einfluß dieser Bäder zu schützen. Es ist zudem unerläßlich, daß diese Bäder neutral !A very hot soap bath is used for deboning the natural silk Acetate silk is not tolerated. So it is necessary to use the acetate against the perishable Protect influence of these baths. It is also essential that these baths are neutral!
sind und Alkali in keiner Form enthalten, da sonst das Acetat angegriffen wird.and do not contain alkali in any form, otherwise the acetate will be attacked.
Es muß also beim Entbasten ein Zusatz von Soda, der sonst oft zur Beschleunigung der Behandlung angewendet wird, durchaus vermieden werden.So when deboning, soda must be added, which is otherwise often to speed things up treatment should be avoided.
Es ist nun wesentlich, daß die Stoffe, die das Acetat schützen sollen, die Seife nicht am Schäumen hindern. Andernfalls wäre die Seife wirkungslos und das Entbasten wie das Entleimen würde gar nicht oder nur unvollkommen bewirkt: Ein Stoff, der diese Bedingungen erfüllte, war bisher nicht bekannt, und es war also unmöglich, ein stark geleimtes Gewebe aus Acetatseide zu entleimen oder ein Mischgewebe aus Acetatseide und natürlicher Rohseide zu entleimen und zu entbasten.It is now essential that the substances that are supposed to protect the acetate, not the soap prevent foaming. Otherwise the soap would be ineffective and the degreasing would be like the removal of glue would not be effected at all or only incompletely: a substance that would Conditions met was previously unknown, and so it was impossible to get a strong To remove glue from a glued fabric made from acetate silk or a mixed fabric made from acetate silk and natural raw silk to remove glue and deboning.
Es ist nun gefunden worden, daß ein Zusatz neutraler Kalisalze (Chlorid, Sulfat, zweibasisches Phosphat usw.) zu den Bädern den gewünschten Zweck vollständig erfüllt.It has now been found that adding neutral potassium salts (chloride, sulfate, dibasic Phosphate, etc.) to the baths completely fulfills the desired purpose.
Die Kalisalze haben (im Gegensatz zu den Salzen anderer Metalle) die merkwürdige Eigenschaft, die Seife nicht am Schäumen zu hindern; sie schützen durchaus die Celluloseacetatfaser, die nach der Behandlung alle ihreThe potash salts (in contrast to the salts of other metals) have the strange property not to prevent the soap from foaming; they thoroughly protect the cellulose acetate fiber, all of theirs after the treatment
Eigenschaften beibehält, selbst wenn eine Temperatur von ioo° verwendet worden ist.Maintains properties even if a temperature of 100 ° has been used.
Ein Gewebe aus Acetatseide, stark geleimt, wird in einem Bade, dessen Menge dem 20- bis öofachen Gewicht des Gewebes entspricht und das 0,5 bis 2 Prozent neutrale Marseillerseife und 5 Prozent Chlorkalium enthält, umgezogen. Man erhitzt auf 95 bis 100°, bis die Appretur entfernt ist, was etwa 30 bis 60 Minuten dauert, und wäscht dann gründlich mit reinem Wasser.A fabric made of acetate silk, heavily sized, is used in a bath, the amount of which is 20 to Öof the weight of the fabric and the 0.5 to 2 percent neutral Marseilles soap and contains 5 percent potassium chlorine, moved. The mixture is heated to 95 to 100 °, bis the finish is removed, which takes about 30 to 60 minutes, and then washed thoroughly with pure water.
B eisp i el 2.Example 2.
Man ersetzt im Beispiel 1 das Kaliumchlorid durch ein anderes neutrales Kalisalz (Sulfat, zweibasisches Phosphat usw.).In Example 1, the potassium chloride is replaced by another neutral potassium salt (Sulfate, dibasic phosphate, etc.).
Ein Gewebe aus roher Naturseide und Acetatseide wird in einem Bade umgezogen, das 0,5 bis 2 Prozent neutrale Marseillerseife und i 10 Prozent Kaliumchloridsulfat oder ein anderes neutrales Kalisalz enthält. Man behandelt bei 90 bis 100°, bis der Bast der Rohseide und die Appretur der Kunstseide entfernt worden sind, was nach 30 bis 60 Minuten der Fall ist. Man spült dann in reinem Wasser.A fabric made of raw natural silk and acetate silk is changed in a bath that 0.5 to 2 percent neutral Marseilles soap and 10 percent potassium chloride sulfate or something else contains neutral potassium salt. It is treated at 90 to 100 ° until the bast the Raw silk and the finishing of the rayon have been removed, which takes 30 to 60 minutes the case is. You then rinse in pure water.
Die angegebenen Mengen von Kalisalz stellen übrigens kein Minimum dar; geringere Mengen haben ebenfalls günstigen Einfluß auf die Erhaltung der Celluloseacetatseide.Incidentally, the stated quantities of potash salt do not represent a minimum; lesser Amounts also have a beneficial effect on cellulose acetate floss maintenance.
Wenn die Rohseide viel Bast enthält, so kann ein zweites schwächeres Seifenbad erforderlich sein, das nachher, verstärkt, als erstes Bad dienen kann.If the raw silk contains a lot of raffia, a second, weaker soap bath may be necessary that afterwards, strengthened, can serve as a first bath.
