Description

PETER SCHMID AND KARL GROSS, 0E BASEL, SWITZERLAND; SAID GROSS ASSIGNOR TO SAID SCHMID.
' METAL-CHLORID BATH FOR WEIGHTING SILK.
No Drawing.
To all whom it may concern:
Be it known that we, PETER SCHMID, a citizen of the Swiss Republic, and KARL Gross, a subject of the King of Prussia, both residing in Basel, Switzerland,-have invented a new Metal-Chlorid Bath for Weighting Silk, of which the following is a full, clear, and exact specification.
It is known that the weighting ofsilk is generally carried out by treating the silk alternately with metal chlorid baths (preferably with tin chlorid baths) and with alkali metal phosphate baths and finally with an.
bath can be advantageously a silk waste,
which already may contain silkworm-chrys alises, as for instance bassinets (Italian gallettamini, French palettes).
The preparation of the new silk weighting bath is illustrated by the following examples:
Example I: In 2 liters zinc chlorid of 54 to Baum are introduced 100 grams pure silk and 100 gr. silkworm-chrysalises (these 200 gr. silk and chrysalises are dissolved in the zinc chloridbath at a low temperature). To this solution is added the quantity of tin chlorid necessary to obtain a mixture containing equal quantities of both chlorids and this mixture is then diluted with water till a solution of 27 to 28 Baum is obtained.
Example II: 100 gr. pure silk and 100 gr.
. silkworm-chrysalises are dissolved in 2 liters tin chlorid of about 27 Baum. In this Specification of Letters Patent.
Patented Aug. 1, 1916.
Application filed October 7, 1915. Serial No. 54,499.
example the tin chlorid can be replaced by zinc chlorid.
In all examples the indicated proportion of sllk and chrysalises may be varied, also the proportion of tin chlorid and zinc chlorid in Example I can be varied.
In all examples the silk weighting bath can be prepared by substituting for the silk and the chrysalises the product obtained by boiling the same with water. The new silk weighting baths are applied 1n the usual manner in liquid form to the silk, while the phosphate baths alternating with them may be employed in form of liquid or of froth. Obviously common salt and acid may be added where necessary to the silk weighting bath.
The use of the new silk weighting bath has the advantage that when a mixture of zinc chlorid and tin chlorid is employed for weighting silk, the same satisfactory results are obtained as by employing the more expensive tin chlorid alone. In all cases the silk weighted by use of the new metal chlorid bath shows a better afiinity for the dye.
What we claim is:
1. A metal chlorid bath. for weighting silk comprising a solution of at least one metal chlorid with silk and silkworm-chrysalises,
ber 1915, in the presence of two subscribing witnesses.
