Description

Patented Nov. 13, 1951 UNITED STATES PATENT OFFICE METHOD OF CREPING NYLON Abraham L. Dorgin, New York, N. Y.
No Drawing. Application March 16, 1949, Serial No. 81,845
14 Claims. 1
This invention relates to the formation of a nylon crepe fabric.
An object of the invention is to provide a creped fabric without embossing or similar process and which, in its finished state, consists solely of nylon or any other similar synthetic yarn.
A further object is to provide a yarn of the character hereafter described which may be woven into fabrics along with other yarns to produce novel effects in the cloth.
I use a yarn which comprises nylon or similar synthetic yarn combined with raw silk in one thread. It may be thrown with half right twist and half left twist or with a one way twist. The number of turns given the yarn is determined substantially by the size of the thread desired. For example, the combination of a 40 denier filament yarn with one end of 20 to 22 denier raw silk would be given about 60 to 65 turns per inch. The silk would constitute about 25% to 50% of the yarn by weight.
This yarn is then used in the manufacture of fabrics either for warp, or filling, or both, depending upon the construction of the cloth desired.
The woven or knitted fabric is boiled off in the usual manner. This boiling off process causes the silk to shrink or contract. In shrinking or contracting, the silk contracts or crinkles the nylon or similar synthetic yarn with which it has been thrown imparting a creped or crinkled effect to the fabric. The nylon or similar synthetic yarn is then set in the aforementioned contracted positi n by the application of heat. The degree of heat applied depends on the type and construction of the fabric but for the reasons set forth below it is desirable that in all cases this degree of heat exceed the boiling point of water.
I have found that the boiling off process supplies sufficient heat to the nylon or other similar synthetic yarn to set it without the necessity of the setting procedure described above. However, the setting by the boil off process sets the nylon or similar synthetic yarn only to the extent of the degree of heat of boiling water, viz., 212 F. I prefer, therefore, after the boil off to set the nylon or similar synthetic yarn at a temperature in excess of the boiling point of water to avoid any possible damage in the laundering process of the finished garment.
The nylon or similar synthetic yarn having been set, it will retain its creped position and is no longer dependent upon the silk for this purpose.
the fabric in a hot caustic solution, the strength Accordingly, the silk is dissolvedby immersing of which depends upon the construction of the cloth itself. The fabric is then treated with an acid bath which neutralizes any of the caustic solution which may remain on the fabric. This caustic solution and acid bath may, if desired, be employed before the setting by the application of heat described above because as shown above, the boiling off process supplies a sufiicient setting to the nylon or other similar synthetic yarn to allow for the removal of the silk after such setting.
The silk having been completely dissolved and removed from the fabric, the result is a fabric which is nylon or similar synthetic yarn with a permanently set creped effect.
Fabrics, when made and finished as set forth above have all of the advanta es of nylon or similar synthetic fabrics as heretofore made with the added advantage that the creped structure forms air pockets and therefore prevents the clinging of the garment to the body of the wearer.
A spun nylon may be used instead of a continuous filament with the same results.
It will be appreciated that many uses may be made of a fabric constructed in accordance with the aforesaid invention but the essential feature of the invention is the contracting and setting of the nvlon or similar synthetic yarn so that it imparts a creped effect to the fabric.
Thrown silk may be used in the place and stead of raw silk.
It is of course possible to form the com osite threads of n lon material and silk and treat them to contract the silk on the nylon thread to produce the creped effect, then treat the thus cre ed composite thread to remove the silk, and then form a fabric of the creped nylon threads, if desired.
I claim:
1. A method of making a fabric wholly of nylon which comprises forming a fabric with yarn consisting of nylon combined with silk. shrinking the silk to give a creped position to the nylon, setting the nylon in this creped position by the application of heat, and dissolving the silk to remove it from the fabric.

5. A method of making a fabric wholly of nylon yarn which comprises forming a fabric comprising such nylon yarn combined with silk in one thread, boiling oil the fabric and shrinking the silk which in turn gives a creped position to the nylon yarn, setting the nylon yarn in this creped position by the application of heat and dissolving the silk and removing it from the fabric by immersing the fabric in a hot caustic solution and in a neutralizing acid bath.
