Method and apparatus for treatment of pile fabric

BACKGROUND OF THE INVENTION
This invention relates to an improved method and apparatus for removing pile distortions in fabric created by heat-setting and/or dyeing.
In the case of pile fabrics, which have been heat-set at a high temperature with the pile erect and then dyed at a lower temperature during which the pile is substantially disturbed, as in jet dyeing, it is then desired to have the pile return to its original erect condition. One attempt in solving this problem is the tensionless dryer. In this machine, the pile fabric is fed onto a mesh belt that is then transported through a long heated tunnel where either mechanical action or perpendicular air blasts directed at the belt cause the fabric to undergo rather gentle undulations. The fabric is statically charged by friction with the air or contact with various parts of the dryer. The required processing time results in a drying unit over one hundred feet long with a low fabric line speed. There are quality problems associated with a lack of control over the fabric for such a long distance and well as marks that occur when the fabric strikes the upper section of the tunnel.
Another type of pile conditioning device is the use of a high velocity air jet such as U.S. Pat. No. 4,837,902.
In this case, the fabric is heated to the desired temperature and the conditioning is accomplished almost instantaneously by vigorous sawtoothed shaped waves that are small in amplitude, but effective due to high accelerations normal to the fabric surface produced by the wave's small bending radius and high velocity. The disadvantage of this process is direct contact of the heated fabric with the air stream, which tensions the fabric and can set in distortions in sensitive knit fabrics. Also, this process is less effective with highly permeable fabrics, as the air may not be trapped between the fabric and plate.
Yet another type of device vibrates and charges the pile fabric in the heated condition by contact with pneumatically excited diaphragms. The contact of the fabric with the diaphragms combined with the rapid vibrations induced by the air stream cause the diaphragm to wear out at a rate in which replacement can be a daily occurrence.
Still another type of device vibrates and charges the pile fabric biaxially by means of a rotating cylindrical roll with spaced protrusions or depressions along the exterior surface of the cylinder, followed by optionally vibrating the fabric axially by means of a second rotating cylindrical roll having flat portions continuously extending along the longitudinal axis of the second cylinder. The repeated and rapid front to back and side to side movement of individual pile fibers caused by multiple vibrational waves during biaxial treatment allows the fibers to return to their preferred heat-set orientation.
The present invention solves the above problems in a manner not disclosed in the known prior art.
SUMMARY OF THE INVENTION
A method and apparatus for continuous treatment of webs of fabric having upright pile comprised of wetting the fabric to at least 50% saturation, heating the fabric to approximately 225.degree. to 350.degree. Fahrenheit and then brushing the fabric in both the pile and counter-pile directions. The presence of liquid and steam plasticize and lubricate the fibers, thereby allowing an easier, more complete return to the uncrushed state.
An advantage of this invention is that it does not require the high temperatures of dry face finishing and also results in a less cloudy or a more clear face finish.
It is another advantage of this invention that it is able to work on wet fabrics so that jet-dyed pile fabrics straight from the dye jet are able to be treated without the need for intermediate drying. This not only reduces processing costs but also reduces wear and tear on the fabric by eliminating a costly pass down a tenter range utilized for drying.
Another advantage of this invention is that the treatment is completely uniform without any highlights.
Still another advantage of this invention is that the crushed pile might be in any direction and will be processed and come out in only one solitary direction.
Another advantage of this invention is that there is a blooming of tuft which provides a cover effect and fullness. It also creates a greater softness in the fabric due to the spreading out of the tuft.
Yet another advantage of this invention is that the fabric may be dried at the same time as treated. This will eliminate another processing step.
Yet another advantage of this invention is that it will allow face finishing of lower melting point fibers such as polypropylene and polyethylene. It is more effective in the transference of treatment to the fabric.
Still another advantage to this invention is that it is very effective with less point contact.
These and other advantages will be in part apparent and in part pointed out below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now by reference numerals to the drawings, and first to FIG. 1, assembly to erect pile fabric is generally indicated by numeral 2. The pile fabric 8 is initially removed, with the pile side down, from a buggy 4 movably supported by four rollers 6. The pile fabric 8 is then directed angularly upward by a first idler roll 10 and then angularly downward through second idler roll 12 which submerges the pile fabric 8 in a container of liquid 16. This liquid can be any variety of chemicals, however, water is preferred. Furthermore, the temperature of the liquid is not critical and can range from between above freezing to boiling. The container of liquid 16 is held in place by a support frame 14. The pile fabric 8 then passes through a pair of nip rolls 18 and 20, respectively. The pile fabric 8 then passes by a vacuum slot 24 having a tube mechanism 22 for expelling the stream of air. This will remove trapped liquid from the pile fabric, leaving it at 100% saturation with no entrapped liquid. However, this does not have to be 100% saturation and can be anything above 50%. The pile fabric 8 then moves vertically upward and then passes over idler roll 26 and onward to the first heating and brushing mechanism generally indicated by numeral 100.
Referring now to FIGS. 1-9, all four heating and brushing mechanisms have identical frame structures. Identical components will only differ by the first number with numbers in the nine hundred series being identical for all heating and brushing mechanisms.

The density of the bristles depend on the effect desired and the type of pile fabric brushed. Cleaning roll 183 needs to be able to engage the bristles of cylindrical brush 184.
