    1524392 Shrink proofing wool KROY UNSHRINKABLE WOOLS Ltd 14 May 1976 [15 May 1975] 20652/75 Heading D1L Wool as sliver, roving, yarn or thread is shrink proofed by immersion for a depth of 1 metre or more into an aq. soln. of hypochlorous acid, the wool being introduced into the soln. at a rate of 7-25 cm/sec and in a direction not exceeding 10‹ from the vertical so that air is displaced from between the fibres and the fibres completely wetted prior to completion of the wool/hypochlorite reaction. The soln. preferably comprises water aspirated with Cl 2 , gas to a pH of 2.0-2.6 with a temp. of 6-20‹C. As shown wool sliver, sandwiched between a pair of endless sieve conveyors 9, 12, is introduced between rolls 5, 14 into the L.H. arm of the U-shaped tank 2 and withdrawn between squeeze rolls 6, 13. Fresh Cl 2 soln. is introduced at 7 and spent liq. removed by drain 6.

    专利说明:

    The invention relates to textile finishing and can be used in the processing of wool fiber material for its non-shrinking.
    The known method of liquid treatment of wool fibrous material by immersing it in an aqueous solution of hypochlorous acid for non-shrinking finishing of fibrous material followed by wringing ij
    The disadvantage of the known method is the difficulty of obtaining uniform processing, since the reaction rate between the wool fiber material and the processing hypochlorous acid is so fast that some fibers can only be wetted with a reagent solution, which has already lost hypochlorous acid in its initial reaction stage, and this leads, further to uneven processing.
    . The purpose of the invention is to improve the quality of processing.
    This goal is achieved by the fact that according to the method of liquid treatment of wool fiber material followed by pressing, when dipped wool material is moved at an angle to the vertical, not exceeding 10, and immersion is carried out at a depth of not less than 1 m at a speed of 7-25 cm / s
    When etodM solution of hypochlorous acid is used with a pH of 2-2.6 and the temperature of the solution is maintained within b-20 ° C.
    The drawing schematically shows a device for implementing the method.
    The device comprises a bath 1 for the treatment liquid, inside which a displacer is installed, 2 for reducing the volume of the bath 1 liquid. Under the displacer 2, a roller 3 is placed with a gap relative to the last one.
    Above bath 1, guide rollers 4 and 5 are installed, which are positioned relative to roller 3 so that the tangent to each of rollers 3 and 4, 3 and 5 is almost vertical, not exceeding 10 to the vertical,
    For supplying the processing liquid to the bath 1 in the upper part of the latter there is a pipe 6, and for discharging the liquid - a pipe 7 located on the opposite side. The pipes 6 and 7 are located at a height of not more than 1 m above the axis of rotation of the roller 3 in order to maintain the appropriate depth of the liquid in the bath.
    For transporting the wool fiber material into the interior of the tub 1, there are two endless mesh conveyors 8 and 9 spanning the support rollers. The conveyor 8 covers the guide rollers 3, 10 and 11, and the conveyor 9 covers the direction of the rollers 4, 5, 12 and 13. The net of the conveyor allows air to escape from the fibrous material from the capillaries, and also contributes to the penetration of the processing liquid into In this case, a solution of hypochlorous acid, into the inside of the fibrous material as it enters the bath.
    The pipeline b for supplying the treatment liquid to the bath 1 is located higher than the pipeline 7 for draining the liquid. Piping 6 and 7 are provided with valves (not shown) to regulate the flow and discharge of fluid from bath 1. Level: The liquid in bath 1 when it is supplied is above the level of liquid 15 when it is drained, i.e. during operation of the device, a constant flow of liquid is carried out.
    The plunging speed of the wool fiber material is controlled by changing the speed of the mesh conveyors 8 and 9. In order not to damage the structure of the wool fiber material, the speed of the mesh conveyors 8 and 9 should be the same.
    The rollers 5 and 11, located at the exit of the fibrous material from the bath 1, should flow tightly one to the other so as to squeeze out any excess liquid from the fibrous material. The pressed liquid will flow back into the bath 1. As the processing liquid is maintained at a height of at least 1 m above the axis of rotation of the guide roller 3, the wool fiber material will also be immersed to a depth of at least 1 m at an angle to the vertical, not exceeding 10. At the same time, all the capillaries of the fibrous material will be free from air and filled with the processing liquid.
    Example. Wool fibrous material is passed between mesh conveyors 8 and 9 with a curvature of 18 cm / s. Bath 1 contains a solution of hypochlorous acid with a pH of 2. The immersion of the fibrous material is carried out at an angle to the vertical, not exceeding Yu. This is due to the fact that the air is displaced upward by the processing liquid, the displacement rate is constant, and the wetting will be uniform.
    5 Swine 1 is kept in the filled

    condition. At the exit of the fibrous 2.0-2.6, and the temperature of the processing material is squeezed out using a roller solution is maintained in pre5 and-11. cases 6–20 ° C.
    Fibrous immersion rate
    Material can be varied from 7fabricated fibrous material
    up to 25 cm / s, a solution of hypochlorous later becomes good
    Acids can be used with pH coloring and other properties.
