Claims
- 1. A method for positioning the pile threads of a textile web having a pile in which the web is required to enter and leave a treatment station with its pile facing upward, the pile threads of the textile web fabricated from a heat sensitive synthetic material comprising the steps of:
- (a) filling a vertical tank with a heated liquid of predetermined temperature, said tank being substantially vertical and having a top and bottom and spaced sides extending substantially vertically between said top and bottom, with an inlet and outlet opening in one of said sides, near the top thereof, said filling being to a point closely adjacent said inlet and outlet opening;
- (b) forming a passageway of width at least equal to the width of said textile web under said vertical tank;
- (c) routing said textile web through said passageway beneath said tank from the one of said sides opposite said opening and upward to said opening and into said heated liquid;
- (d) guiding said textile web through said heated liquid, first vertically downward and then vertically upward for a predetermined period of time in such a manner that only the backside of said web is contacted by anything other than said heated liquid;
- (e) removing said textile web from said heated liquid in such a manner as to change the direction of said web from vertical to substantially horizontal thereby bringing said web to a substantially horizontal position immediately after removal from said heated liquid; and
- (f) removing said web from said tank through said opening above the point at which said textile web is quided into said vertical tank while maintaining said web substantially horizontal for a second period of time.
- 2. The method of claim 1 further comprising the step of dyeing said textile web subsequent to the steps of claim 1.
- 3. The method of claim 1, and further including the step of forced cooling said web after removal from said heated liquid to shorten said second predetermined period of time.
- 4. The method of claim 3, wherein said step of forced cooling includes removing, by suction from the pile side and without contact, a substantial portion of the heated liquid which is retained by said web upon removal from the heated liquid in said tank, after said web has passed through said opening.
- 5. The method of claim 4, and further including the step of removing, by suction from the pile side without contact, a portion of the heated liquid which is retained by said web immediately after said web leaves said heated liquid while said web is still within said tank.
- 6. The method of claim 5 further comprising the step of returning the removed heated liquid, collected in said steps of removing said liquid from said web to said vessel.
- 7. The method of claim 6 further comprising the step of agitating said web prior to routing said web through said vessel.
- 8. The method of claim 5 further comprising the step of agitating said web prior to routing said web through said vessel.
- 9. The method of claim 1 further comprising the step of agitating said web prior to routing said web through said vessel.
