Abstract
Abstract The method of treating textile material by passing the same under tension through a body of treating liquid in a treating zone while applying rubbing contact to the textile material at staggered points on opposite sides thereof and while subjecting the treating liquid and points of rubbing contact to vibration. A constant head of the treating liquid is maintained in the treating zone by adding treating liquid to the zone at a rate faster than it is being absorbed by the textile material. The excess treating liquid is collected, filtered and returned to the treating zone so that continuous circulation thereof occurs.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
48 words
The method of treating textile material as defined in claim 1, including the step of: vibrating the body of treating liquid and vibrating the rubbing points of contact on said opposite side of said textile material during the application of the rubbing contact pressure to the textile material.
Claim 2
Dependent Claim
64 words
The method of treating textile material as defined in claim 1, including the step of: continually draining off a portion of the treating liquid from said body; adding treating liquid to said body at a rate faster than it is being drained; and removing the excess treating liquid after being added in order to maintain a constant volume of treating liquid in said body.
Claim 3
Dependent Claim
43 words
The method of treating textile material as defined in claim 3, including the step of: continuously collecting together the excess treating liquid removed from said body, and the treating liquid drained from said body; filtering the same; and returning it to said body.
Claim 4
Dependent Claim
101 words
The method of treating textile material as defined in claim 1, including the step of: maintaining the liquid body at a constant level by simultaneously and continuously draining treating liquid from a lower portion of said body, replenishing said body with treating liquid at a rate faster than it is being drained therefrom; withdrawing the excess treating liquid from the upper portion of said body after it has been added to said body; collecting together the excess treating liquid supplied to said body and the treating liquid drained from said body; filtering the same; and returning it to said liquid body.
Claim 5
Dependent Claim
28 words
The method of treating textile material as defined in claim 1, wherein the body of treating liquid is maintained under a constant gravity head in a treating zone.
Claim 6
Dependent Claim
37 words
The method of treating textile material as defined in claim 6, including the step of squeezing excess treating liquid from the textile material after it has passed through the body of treating liquid in the treating zone.
Claim 7
Dependent Claim
19 words
The method of treating textile material as defined in claim 1, wherein the treating liquid is a dye solution.
Claim 8
Dependent Claim
20 words
The method of treating textile material as defined in claim 1, in which the treating liquid is a sizing material.
Claim 9
Dependent Claim
33 words
The method of treating textile material as defined in claim 1, wherein the textile material is moved through the body of treating liquid at a rate of 300 to 500 yards per minute.
Claim 10
Dependent Claim
29 words
The method of treating textile material as defined in claim 2, including the step of electrically heating the treating liquid to maintain the same at a substantially uniform temperature.
Claim 11
Dependent Claim
52 words
The method of treating textile material as defined in claim 2, wherein the points of rubbing contact in the body of treating liquid are vibrated at an amplitude of from next to zero to one-half inch and at a frequency that is optimum for the viscosity of the particular treating liquid employed.
