Description

       

   <EMI ID=1.1> 

  
Les solutions alcalines d'albumine utilisées pour le filage a

  
sec ont tendance à fermentation ou putréfaction* L'apparition

  
de la fermentation ou putréfaction se constate non seulement par

  
le dégagement d'une odeur désagréable, mais elle se manifeste

  
au...si dans les qualités de la .solution au point de vue du filage.

  
La filabilité de la solution alcaline d'albumine diminue lorsque

  
le degré de fermentation croît, et elle disparaît en fin de

  
compte totalement. Il est par conséquent nécessaire d'empêcher

  
autant que possible la fermentation des solutions alcalines d'albumine destinées à être soumises au procédé de filage à sec.

  
Il a main tenant été constaté que, dans l'appareil servant

 <EMI ID=3.1> 

  
 <EMI ID=4.1> 

  
lisation, tandis que la vitesse d'écoulement est considérable au

  
centre des sections transversales. Si l'on produit donc une

  
consolation rapide des solutions à filer, par une augmentation

  
de la quantité refoulée par unité de temps, on n'obtient encore

  
aucun résultat, étant donné que,. pendant leur écoulement à travers l'appareil, les solutions fraîches sont continuellement infectées

  
par les parties de solutions plus anciennes qui sont restées en

  
contact avec les parois des canalisations. Il en résulte aussi

  
une attaque rapide des solutions fraîches, et un développement

  
indésirable de la putréfaction.

   <EMI ID = 1.1>

  
Alkaline solutions of albumin used for spinning have

  
dry tend to fermentation or putrefaction * The onset

  
fermentation or putrefaction is not only observed by

  
the release of an unpleasant odor, but it manifests itself

  
au ... if in the qualities of the solution from the point of view of spinning.

  
The spinability of the alkaline albumin solution decreases when

  
the degree of fermentation increases, and it disappears at the end of

  
totally counts. It is therefore necessary to prevent

  
as far as possible the fermentation of alkaline solutions of albumin intended to be subjected to the dry spinning process.

  
It has now been observed that, in the device serving

  
 <EMI ID = 2.1>

  
different speeds, at different points of the cross-sections

  
 <EMI ID = 3.1>

  
 <EMI ID = 4.1>

  
lization, while the flow velocity is considerable at

  
center of cross sections. If we therefore produce a

  
rapid consolation of solutions to be spun, by an increase

  
of the quantity repressed per unit of time, we still do not obtain

  
no result, given that ,. as they flow through the apparatus, fresh solutions are continually infected

  
by the parts of older solutions that have remained in

  
contact with the walls of the pipes. It also results

  
rapid attack of fresh solutions, and development

  
unwanted putrefaction.

 <EMI ID = 7.1>

  
rinse all the pipes and all the receptacles through which the solution circulates, for this purpose, the

  
 <EMI ID = 8.1>

  
pipe, or the supply of rinsing water to the desired inuroits.

  
Another advantageous measure is to shorten as much as possible the paths followed by the solution within

  
 <EMI ID = 9.1>

  
arrange for all paths followed by

  
the solution to. spinning in the apparatus are free of pocnes or places where the solution can stay for a long time. For this purpose, round the elbows, avoid spaces in which the solution can stay for a long time, and make the sections transparent.

shortens as much as possible the paths followed by the spinning solution in the spinning apparatus.
