DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
My invention relates to treating cotton staple to impregnate such and like fibers with chemicals. The process and apparatus quickly and thoroughly impregnates cotton and like fibers with chemicals.
BACKGROUND ART
Conventional methods of chemically treating fibers as in U.S. Pat. Nos. 1,635,865 and 2,868,005 and the currently made PETRIE/Wira Wool Scourer treat a mass of fibers by impacting such mass with impellers in a mass of liquid to drive fibers into the liquid while this process and apparatus provide for treating individual fibers by kneading actions on individual fibers while separated from the remainder of the mass of fibers and thus drive liquid into fibers and so impregnate such fibers with chemical-containing liquors.
DISCLOSURE OF INVENTION
The process provides for mixing fibers with chemical-bearing liquor, positioning the fibers in extremely thin films, arranging such thin films on flat support surfaces, dewatering the resulting thin films and thereafter kneading such fibers to impregnate the lumen of such fibers with liquor. Such operation rapidly locates the chemical bearing liquor within the fiber, whereby such chemicals are more permanently located within such fiber than by processes using only the exterior surface of the fiber. The apparatus and process also provide a momentum and impact action on the exterior surface of the treated fibers that enhances the absorption of liquid into such fibers.
BRIEF DESCRIPTION OF DRAWINGS
FIG. 1 is a plan view along the section 1A--1A of FIG. 2, of aparatus 20 at rest and empty.
FIG. 2 is a vertical longitudinal sectional view, along Section 2A--2A of FIG. 1, of apparatus 20 when at rest.
FIG. 3 is a side view of apparatus 20 along the direction of arrow 3A of FIG. 1 and partly broken away along section 3B-3C-3D.
FIG. 4 is an enlarged showing of a typical fiber portion as portion 4A of FIG. 5, and is to scale.
FIG. 5 is a diagrammatic perspective view of a fiber showing the reversals of the spiral pattern therein.
FIG. 6 is a transverse enlarged view along section 6A--6A of FIG. 4 to show the structure of the fiber internally.
FIG. 7 is a diagrammatic perspective view of paddle assembly 50 during operation of the apparatus 20.
FIG. 8 is a diagrammatic scale view of zone 8A of FIG. 7 to show detail of the paddle plate structure.
FIGS. 9-11 and 12-14 are diagrammatic views of kneading action on single fibers 187 and 207 respectively during operation of the apparatus 20.
BEST MODE FOR CARRYING OUT THE INVENTION
The apparatus 20 comprises a housing assembly 21, a paddle assembly 22, a roller assembly 24 and a drive assembly 23 on a base 159. Housing assembly 21, power assembly 23 and discharge roller assembly 24 are firmly attached to a rigid base 159 which rest on the ground 158. Paddle assembly 22 is supported in housing assembly 21. Power assembly 23 is operatively attached to and drives the paddle assembly 22 and parts of the discharge roller assembly 24. The frame 159 firmly locates the housing assembly 21 relative to the drive assembly and the roller assembly.
In operation a mass of cotton fibers is fed into the housing assembly and is acted upon by the paddle assembly and the discharge roller assembly 24.
The housing assembly comprises, in operative combination, a vertical longitudinally extending left side housing panel 31, a vertical longitudinally extending right side housing panel 32, a floor panel 33, a roof panel 34, vertical feed end panels 35 and 37, vertical discharge panels 36 and 38 and chutes 161, 163, 166 and 167. Panels 31-38 are rectangular in shape and imperforate and rigid. These panels are firmly joined together at their edges to form a rigid housing chamber 40 that is rectangular in vertical longitudinal section, as shown in FIG. 2 and in horizontal transverse section, as shown in FIG. 1, as well as in vertical transverse section.
The housing assembly 21 encloses a housing chamber 40. The housing chamber 40 has a horizontal rectangular housing inlet or feed opening 48 located and extending between the
