called sizing.
When the threads are woven, it is necessary to remove the sizing therefrom before subjecting them to the preparatory dyeing treatment. ing the sizing are numerous; for the reason that the sizing methods which are most used, because they are most advantageous for weaving, are not those in which what may be termed the 'desizing is accomplished in the easiest manner.
In order to desize the fabrics which have been treated for weaving, they must be treated in very hot soap baths, which is very detrimental, as the artificial silk loses its lustre, becomes cotton-like in appearance, and less resistant.
Mixed fabrics of raw natural silkand of artificial silk need also to be thoroughly treated before dyeing or bleaching.
In order-to accomplish the degumming of raw natural silk, it is necessary to use a very hot soap bath to which cellulose This treatment is technically acetate silk could not be exposed at all,
when treating 1 it is therefore necessary, mixed fabrics, to protect the artificial silk against the noxious action of the degummin bath. Moreover, this bath must be abso utely neutral and not contain alkali in any form, or the acetate fibres would be more or less attacked.
It is therefore necessary to avoid adding to the degumming baths sodium carbonate,
which salt is often added to accelerate'the operation. On the other hand, the agent protecting the artificial silk fibre must not the soap from forming a lather,

the degumming would not take place, or would occur in a very imperfect manner.
Hitherto such an agent was unknown, and it was not possible to dye fabrics of artificial silk, strongly sized, and still less possible to dye mixed 'fabrics'of artificial and raw natural silk. Ithas been discovered that the addition of neutral salts of potassium sulphate, dibasic phosphate, and the like) to the degumming soap bath provides a solution to the problem of protecting the artificial fibre and is satisfactory in eve respect.
These salts (in contradistinction to the salts of other metals) have the curious property of not preventing in the least the soap from forming a lather, while they perfectly protect the fibre of cellulose acetate silk, which retains after the treatment all its original properties even if the temperature of the bathhas been raised to 100 C.
Eivample I.
V Example I I In Example I, for the potassium chloride is substituted a'nother neutral potassium salt m (sulphate, 'dibasic phosphate or the like);
0 Example III.
' A mixed fabric of artificial and of raw natural silk is treated in a bath containing 0.5 to 2% of neutral soap (Savon de Marseille) and 10% potassium chloride, sulphate or other neutral potassium salt. The temperature is raised to -100 0., until the gum of the natural silk and the sizing of the artificial silk are removed and have passed into the bath, which requires from 30 to 60 minutes. The fabric is then withdrawn and rinsed with soft water.
It will be understood that the potassium 98 salts may be used in quantities less than those mentioned in the examples, and still have a beneficial effect on the preservation of the artificial Silk.
It the raw silk contains much gum, one will give a second and lighter soap bath which, replenished, may be used for the first bath in the following operation.
What I claim and desire to secure by Letters Patent is 1. A process of treating fabrics, which consists in subjecting the fabric to a hot Soap bath containing a neutral potassium salt.
Zia process of treating fabrics, which consists in subjecting the fabric to a hot soap bath containing potassium chloride.
3. A process of treating fabrics, which consists in subjecting the fabric; to a hot soap bath containing .5 to 2% of neutral soap and .5 to 10% of potassium chloride.
4t. A process of treating fabrics, which mamas consists in subjecting the fabric to a soap bat-h containing a neutral potassium salt, and raising the temperature of such bath to 100 C.
5. A. process of treating fabrics, which consists in subjecting the fabric to a soap bath containing .5 to 2% of neutral soap and from .5 to 10% of potassium chloride, and raising the temperature to 100 C.
6. A process for treating mixed fabrics composed of artificial silk fibre and natural raw silk to remove sizing from the former and degum the latter, which consists in subjecting the fabric to a hot soap bath containing a neutral potas ium salt.
In testimonv whereof I have signed my name to this specification.
