Description

July 17, 1934. A. NUERNBERG APPARATUS FOR TREATING FABRICS Original Filed Aug. '27. 1931 INVENTOR (iii/raw (/Vue/wJe/y BY ATTO R N EY WITNESSES 224% 9220 Patented July 17, 1934 UNITED STATES PATENT OFFICE Renewed June 9, 1934 2 Claims.

An object of the invention is to provide a new and inexpensive method of treating fabrics which gives the fabric treated a richer finish which is apparent when the fabric is 5 handled, and which is also apparent to the eye of the observer.

Another object of the invention is to provide a method of the class described which, while not increasing the weight of the fabric treated, will give the fabric the appearance of being heavier in weight than it is.

Still another object of the invention is to provide an apparatus for carrying out the method.

Additional objects of the invention will appear in the following specification in which the preferred from of the invention is described.

In the drawing similar reference characters refer to similar parts in all the views in which Figure 1 is a side sectional elevation showing the apparatus used in carrying out the method, and

Figure 2 is a plan view of Figure 1.

It will be understood that the method which is the subject matter of this application may be used to treat silks, Woolens, cottons, rayons, and all other fabrics.

In carrying out the method which is the subject matter of this application, the fabric is heated, for instance by dry heat or by hot moisture or steam, the fabric being immediately thereafter chilled with a refrigerant fluid, which is preferably not only below 32 Fahrenheit, but is preferably below zero, the fabric being immediately thereafter again heated, by dry heat or hot moisture. It will be understood that the fabric may be treated qiuckly in the open without expensive apparatus or machinery, and, therefore, inasmuch as the fabric may pass quickly through the apparatus, the fabric may be treated at very little expense.

Preferably, the refrigerant which is used to treat the fabric between the heating stages is 45 a gas, and this gas may be carbon dioxid, air

which may be compressed, or any other compressed gas which, when released through small openings create the proper chill for the fabric being treated.

50 In carrying out the method, the fabric may be disposed on a reel 10, the fabric 11 passing over a roller 12, and then across the top 13 of the heating chamber 14, the top 13 of this chamber 14 having preferably outlets 15 for the steam. The fabric then passes under a roller 16, the rollers 12 and 16 serving to hold the fabric in close proximity to the top 13 of the steam table 14, the fabric passing from under the roller 16 between two or more sets of nozzles, the upper set of nozzles being indi- 50 cated by the reference characters 17, and the lower set of nozzles being indicated, by the reference characters 18. These nozzles 1'7 and 18 are spaced apart so that the fabric may pass between the said nozzles, as illustrated in Fig- 5 me 1 of the drawing. The nozzles 17 and 18 are fed with a refrigerant by a pipe 19, which is preferably connected with a container 20 for feeding the refrigerant fluid through the pipe 19 to the nozzles 17 and 18. From between the nozzles 17 and 18, the fabric 11 passes under a roller 21 and then over the top 22 of a second steam table 23, the steam table 23 having outlets 24. From the steam table 23, the fabric passes over a roller 25 and then to a reel 26 on which the fabric is wound.

The steam tables 14 and 23 have pipes 27 through which steam is directed to the said tables, the steam at the tables 14 and 23 serving to heat, and preferably to moisten, the fabric with steam before and after the fabric is treated by the passage of the refrigerant through the nozzles 1'? and 18 against the fabric.

The first or last stage may be dispensed with to obtain different finishes, provided, however, that the all important middle or refrigerant stage is strictly adhered to in conjunction with either the last or first stage or both as already described.

What is claimed:

1. In an apparatus for treating fabrics, two heated tables spaced apart, a spray nozzle disposed between the heated tables, means to feed a refrigerant fluid to the nozzle, means to supply steam to the tables, and means to direct a fabric over one of the tables, by the nozzle, and to and over the other table.

2. In an apparatus for treating fabrics, two heated tables spaced apart, nozzles disposed between the tables for directing sprays in the direction of each other, means to feed a refrigerant means to the nozzles, means to supply the tables with steam, and means to direct a fabric over one of the tables between the nozzles and over the other table.
