PROCESS FOR LUSTERING- AND FINISHING SILK THREADS.

Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed October 27, 1908. Serial No. 4=59,740.

To all whom it may concern: Be it known that I, EDWARD Form, a cltlzen of the United States of America, and av resident of New York, county and State of 5 New York, have invented a certain new and useful Process for Lustering and'Finishing Silk Threads, of which the following is a specification.

My invention relates to methods oftrea l0 ing silk threads in which a finishing or lustering solution is first applied to the threads and the threads thereafter ironed and polished. Threads thus treated present smooth, unbroken, and highly polished surfaces to the eye, the fibers which usually project laterally from silk threads being all laid during the operation and retained in such condition by the finishing or lustering material. This laying of the fibers is, however,

not desirable in most cases, the loading and polishing of the threads being what is desired, and not the laying of the fibers. When the threads are finally used in the weaving of silk cloth the-loaded and polished threads will give the body required and also the polished surface or sheen so sought after, but goods made of threads sotreated, when rubbed together, will not produce the desired rustle or swish, and" it is the absence of the projecting fibers which is accountable for this. The trade and public require this rustle or swish of silk cloth, and it isthe object of my present inventionto treatsilk threads in such a manner that though loaded and'polished the fibers shall still be permitted to project laterally therefrom so that this rustle or swish may result in goodsmade up there" from. To this end I rupture or break the 40 surface of the lusteringor finishing material after it has been applied, dried, and ironed upon the threads, so as to release the fibers which have been laidthereby andto permit them to once more project laterally from the surface of the threads. This rupturing of the surface of the finishing material may be brought about in any'desired manner, and

suitably dissolved and held in solution while being applied. The threads may be dried andv ironed in any suitable manner, as, for instance, by drawing the same over a heated contact surface, all in a manner which will i be well understood by those skilled in this a Suitable take-up means, as, for instance, a spool winding apparatus may be provlded for drawmg the threads over the surface and winding them on to spools into condition ready for further use. What I clalm 1s: 1. The herein described process of lustermg and finishing'silk threads which consists in first applying a finishing or lustering solution to the threads, whereby the threads are loaded andthe fibers laid, in then drying and ironing the threads so treated, and in finally rupturing the surface of the dried and ironed finishing or lustering material to release the laid fibers.

2. Thehereindescribed process of luster- Jing and finishing silk threads which consists 1n firstapplying a finishing or lustering solution to the threads, whereby the threads are loaded and the fibers laid, in then drying and ironing the threads, and in finally rubbing the threads across the edge of a contact element so as to rupture the surface of the dried and ironed finishing or lustering material in order to release the laid fibers and to permit them to project laterally.
