Definitions

  • ABSTRACT This disclosure teaches a method and a related apparatus for pretreating cellulosic fabrics with liquid ammonia to improve their comfort characteristics as well as their resistances to shrinking and wrinkling and to enhance their affinities for dyes, flame retardants, resins and the like and generally to condition the fabrics better for subsequent finishing operations.
  • a fabric is impregnated with liquid ammonia and is subjected quickly (from about 0.6 to about 9.0 seconds and preferably from about 1.8 to about 3.6 seconds) to removal of the ammonia by drying the fabric so as to achieve these desired results without effecting substantial shrinking of the fabric.
  • the time interval between the impregnation with and the removal of the ammonia from the fabric is controlled preferably by regulating speed of advance of the fabric and by regulating length of path of the fabric from the impregnation with the liquid ammonia. to commencement of the removal.

  • Liquid ammonia has been used for preshrinking of certain fibers and it has been used (as discussed in U.S.
  • the present invention provides a method and related apparatus for mercerizing cellulosic fabrics with liquid ammonia by immersing the fabrics in the liquid ammonia and then quickly removing the liquid ammonia from the fabrics (within from about 0.6 to about 9.0 seconds and preferably within from about 1.8 to about 3.6 seconds), before the fibers of the fabrics have an opportunity to shrink in any substantial amounts.
  • one object of the present invention is to use liquid ammonia instead of an aqueous caustic soda solution for mercerizing cellulosic fabrics so that the fabrics derive improved extensibility (or stretch), improved resistances to shrinking and wrinkling (or creasing) as well as enhanced affinities for dyes, flame retardants, resins and the like, all without degradation of fibers.
  • Another object of this invention is to enable mercerizing of many fabrics, such as denims and corduroys, which could not be mercerized practically by use of aqueous caustic soda solutions.
  • Still another object of this invention is to accommodate mercerizing of knitted fabrics by liquid ammonia.
  • Still another object of this invention is to control shrinking (especially of knitted fabrics) during liquidammonia mercerizing.
  • Still another object of this invention is to provide an apparatus of the type suggested which incorporates means for an operator to regulate speed of advance of the fabric and means to regulate length of path of the fabric from impregnation with the liquid ammonia to commencement of removal of the ammonia.
  • Still another object of this invention is to minimize tension requirements, so that mechanical requirements of the apparatus are simplified. Minimizing of tensions also reduces power needs of the apparatus.
  • Still another object of this invention is the use of an apparatus of the type suggested with a small treating volume so that necessary startup and shutdown periods are kept to a minimum.
  • Still another object of this invention is to furnish an apparatus of the type suggested that is economical to build and operate and is well suited otherwise to its intended function.
  • the apparatus is for carrying out treatment of cellulosic fabrics on an industrial scale. In order that this treatment might be done, it is necessary that the apparatus be capable of processing large quantities of fabrics with consistent and uniform results in a safe manner. Furthermore, it is important that the apparatus be capable of processing a wide variety of fabrics, light and heavy, low cellulosic content and high, loosely woven or knitted and tightly woven or knitted, etc.
  • FIG. 1 is a somewhat idealized elevational sectional view of an apparatus to carry out liquid-ammonia mercerizing of cellulosic fabrics.
  • FIG. 2 is a somewhat idealized plan view of the apparatus of FIG. 1.
  • FIG. 3 is an enlarged elevational schematic representation of a tension control system which forms a part of the apparatus.
  • FIG. 4 shows shrinkage and treatment time relations in the warp direction at various tensions for a cotton fabric.
  • FIG. 5 shows shrinkage and treatment time relations in the fill direction at various tensions for a cotton fabric.
  • FIG. 6 depicts barium activity number as a function of treatmenttime with liquid ammonia for a cotton fab- I'lC.
  • FIG. 7 is a photomicrograph of fibers from a cotton fabric untreated.
  • FIG. 8 is a photomicrograph similar to that of FIG. 7 for a cotton fabric treated for one second.
  • FIG. 9 is a photomicrograph similar to that of FIG. 7 for a cotton fabric treated for five seconds.
  • FIG. 10 is a photomicrograph similar to that of FIG. 7 for a cotton fabric treated for thirty seconds.
  • FIG. 4 is a plot of shrinkage in the warp direction as a function of duration of liquidammonia treatment with various tensions applied to the warp for a cotton fabric.
  • the curves from the 10 pound load to the 1 pound load were determined empirically and refer to tensions of 10 pounds to 1 pound per inch of fabric width respectively.
  • the curve labeled No load is an extrapolated estimate of shrinkage which would occur under no load.
  • a test method to determine degree of mercerization is covered in AATCC 89-l958T. This test is based on the fact that mercerized cotton absorbs more barium hydroxide than does untreated cotton, and so barium hydroxide may be used to determine quantitatively the extent of mercerization. In using this test it is important that no other barium ion absorbing materials be present, for example finishes or other fibers. Carefully scoured and cleaned specimens from a sample (and an unmercerized control) are immersed in 30 milliliter baths of 0.25N barium hydroxide, an alkali, for 2 hours at F. .10 milliliters of each solution are then titrated with 0.lN hydrochloric acid.
  • the mercerized cotton sample will absorb a greater amount of barium hydroxide than will the control sample; therefore, the amount of barium hydroxide remaining in solution will be lower, and the amount of hydrochloric acid required for neutralization will be lower.
  • the amount of hydrochloric acid required for neutralization thus becomes a quantitative measure of the amount of barium absorbed.
  • mercerized samples should have a barium activity number of from 150 to to be considered properly mercerized.
  • FIG. 6 there is plotted an envelope of data on barium activity numbers taken on materials treated with liquid ammonia for various durations. Assuming that the representative curve for the data presented falls in the center of the envelope, it is approximated by the dashed median curve between 0 and 30 seconds.
  • FIGS. 7 through 10 were taken from random yarns selected from the respective specimens. These yarns have been mounted in a medium which has been selected carefully not to effect the condition of swelling of cellulosic fibers. Specimens then were sliced into thin wafers in planes normal to their fiber axes and were photographed at 500 magnifications using light transmitted through the specimens.
  • the photomicrograph from an untreated control specimen is shown in FIG. 7 and reveals the typical bean shape of cotton fibers. A few of the fibers appear to be swollen and lack the bean shape; however, the number of these fibers is small compared to the total number of fibers shown in the photomicrograph.
  • the photomicrograph for a yarn specimen given a I second liquid-ammonia treatment shows a number of fibers on the outer surface of the yarn to be swollen while fibers near the center retain their classic bean shape.
  • An inspection of the yarn which was treated for 5 seconds, as shown in FIG. 9, and the yarn which was treated for 30 seconds, shown in FIG. 10, indicates a larger number of fibers on the outside surface to be swollen.
  • the yarns of FIGS. 7, 8, 9 and 10 were taken from fabrics which correlate with point 0, l, S, and 30 of time on the curve shown in FIG. 6. There is a significant difference in the degree of swelling (mercerizing effect) observed for liquid ammonia treated cotton fibers when compared to the untreated control cotton fibers. This clue and thesteep slope of the barium activity versus duration of liquid ammonia treatment curve in FIG. 6 led to a deduction, which was thereafter proven empirically, that satisfactory mercerization can be effected without undesirable shrinkage effects, provided the time for ammonia treatment of cellulosic fabrics is kept to a sufficiently short duration.
  • FIGS. 1, 2 and 3 A preferred arrangement of apparatus for carrying out the method of this invention is shown in FIGS. 1, 2 and 3.
  • a web 11 of a cellulosic fabric is advanced continuously through an ammonia treatment chamber 12 in which an immersion trough 13, a bow roller 14, a pair of padder rollers 15, a tension controller 16, a delay roller system generally designated 17 and a dryer 18 are housed.
  • the fabric web 11 is fed through an inlet seal 19, around a roller 21 and under a wetting roller 22 into a pool 23 of liquid ammonia in the immersion trough 13.
  • the immersion trough 13 has near its upper level a float 24 connected via an arm 25 to a switch 26.
  • the switch 26 relates to a solenoid 27 which operates a valve 28 in a line 29.
  • the line 29 feeds the immersion trough 13 via a line 31 penetrating into a cabinet 32 which encloses the chamber 12.
  • a manual valve 33 is opened and another manual valve 34 is closed.
  • the valve 33 in the line 29 is closed and the valve 34 in the line 31 is opened.
  • the contents in the immersion trough 13 may be emptied via a valve 35 and a line 36 into a pan 37 which is provided with a heating coil 38 to vaporize the ammonia therefrom for discharge via line 39 and vent 41 to suitable incineration or recovery means (not shown).
  • the immersion trough 13 may be raised or lowered (as indicated by dashed lines in FIG. 1) to control immersion of the fabric web 11 into the pool 23 of liquid ammonia.
  • vent 41 communicates with suitable exhaust means (not shown).
  • the cabinet 32 is jacketed with an insulating material 42 interposed between an inner lining 43 and an outer lining 44.

  • the fabric web 11 After being wetted with the liquid ammonia in the immersion trough 13, the fabric web 11 is delivered to the bow roller 14 which spreads and smooths the fabric web 11 before it passes between the padder rollers 15. Excess liquid ammonia removed from the fabric web 11 (by the action of the padder rollers 15 as well as by the action of the bow roller 14) is caught in a pan 52 for gravity-flow return to the immersion trough 13. From the padder rollers 15 the fabric web 11 is delivered to a roller 53 and thence over a series of alternating stationary rollers 54, 55 and movable rollers 56, 57.
  • This series of rollers comprises the delay system 17.
  • the movable rollers 56, 57 are movable vertically as will be discussed in detail to control length of path of the fabric web 11 between the time it is impregnated with liquid ammonia in the trough 13 and the time removal of the liquid ammonia commences by drying of the fabric web.

  • the blanket 61 is endless and it is cycled by means of rollers 63 over a heated drum 64.
  • the fabric web 11 leaves dryer 18 via exit rollers 65 and the outlet seal 45 out of the ammonia-treatment chamber 12. Spraying of the fabric web with water or steam and redrying can also be employed thereafter to remove any ammonia that remains in the fabric.

  • the lowering of the support member 66 lowers the rollers 56, 57 to reduce accordingly the web tension and this continues until the tension reduces enough to fall within a prescribed range at which time the flexible confinement 79 expands sufficiently to move the movable contacts 77, 78 out of engagement with the stationary contacts 75, 74 and the motor M then shuts off.
  • a similar mode of operation occurs if the web tension falls below a certain value, except in this case the flexible confinement 79 expands to move the movable contacts 77, 78 upwardly into respective contact with the stationary contacts 73, 76 thereby energizing the motor M and effecting current flow in the direction of arrow i to rotate the motor M in the other direction to cause raising of the rollers 56, 57 accordingly to increase the web tension.
