Definitions

  • My present invention relates to improvements in the compressive shrinking of woven textile fabrics.
  • it is a principal object of my invention so to compressively shrink certain textile fabrics as greatly to improve the surface finish thereof, while substantially increasing the output of existing machines upon which they are processed.
  • the fabric passes beneath a heated metal block during its travel around the roll above mentioned, with the result that the polishing effect otherwise obtained, is enhanced.
  • some of the moisture in the web escapes through the pores of the felt, and after the shrinking operation the web is further dried by passing it over one or more heated drums against which it is constrained by a suitable belt.
  • the invention is thus particularly concerned with the compressive shrinking of fabrics of the type whose surface is ridged or exhibits a raised pattern, as for example, denims and twills, as well as satins, sateens, herringbones, etc., or such surface may be a pile surface.
  • the raised pattern surfaces are characterized by the recurring presence of floats of warp yarns over the filling yarns, or vice versa, the term float being applied to a type of weaving in which the warp yarns span two or more filling or weft yarns (or vice versa).
  • the appearance of the fabrics above mentioned is in general much enhanced if the somewhat rough character or bloom of the surface produced is preserved during the compressive shrinking step. However, when these fabrics are passed through the compressive shrinker of the rubber belt type, this roughness tends to be smoothed out, with consequent loss of bloom and impairment of the value of the fabric.
  • my invention is also applicable to the compressive shrinking of any fabric as to which one face need not be polished; thus in some instances two plies of fabric may be processed back-to-back, in which case one face of each fabric will receive a high polish, whereas the backs thereof will not, but the output of the machine will be doubled.
  • More specific objects of my invention are hence to provide a novel method for achieving the improved results above set forth. It is a further object of my invention to provide a novel arrangement of apparatus which will permit the conveying of single plies of textile fabric separately to the compressive shrinker, and during such travel separately to subject them to treatment by moisture and heat to render the fibers plastic, and thereafter combine them in a single sheet for introduction into the shrinker. A still further object is so to contrive such arrangement as to keep the longitudinal axes of the respective plies in substantially the same vertical plane.
  • I first condition the webs as by subjecting them to controlled moisture and heat conditions prior to the shrinking step, as is usual, but in so doing, I preferably pretreat each web or ply separately in known manner.
  • the webs may each be subjected to the action of so-called clip tenters or stretchers, or similar devices, which place the web in tension crosswise. In this manner any tendency to form longitudinal wrinkles is prevented, and the two webs are brought to the same width.
  • the tenter acts to guide the fabric to the shrinker. While highly useful in many instances, the tenter may not be necessary in others, as when the web does not need to be placed under tension widthwise.
  • a further advantage is that the two fabric webs which are processed may have somewhat different shrinkage characteristics, but after processing will nevertheless have achieved substantially the same desired stability to resist shrinkage. In this situation, both fabrics will be compressively shrunk to the amount required by the one having the highest potential shrinkage whereby the other fabric will be somewhat over-shrunk.
  • FIGURES 1 and 1A when placed end to end at line aa show diagrammatically in side elevation, a layout of apparatus suitable for carrying out the improved method
  • FIGURE 2 is a diagrammatic view in elevation illustrating the principle of compressive shrinking on a rubber belt machine.
  • FIGURE 1 denotes one of the webs, the under web, which is brought to the machine in bulk supply in folded condition in a cart 11, while 12 denotes the upper web which is brought to the machine folded in cart 13.
  • Web 10 is fed over conventional conveying and tensioning rolls and scrimp bars among which may be mentioned roll 15, scrimp bars 16, rolls 17, 18, 19, 20, 21, 22, which bring itwithin the moistener 25 comprising a chamber 25a which affords time for the moisture from nozzle 25b to take full effect by virtue of the vertical runs afforded by conveying and tensioning rolls 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35.
  • Thence ply 10 passes out of chamber 25a beneath guide roll 36 to heating drum 37, the purpose of which is to heat the web sufficiently to promote the plastic action of the moisture without undue drying.
  • both webs are preferably respectively fed to clip tenters 40, 40 where they are placed in crosswise tension and brought to the same width.
  • clip tenters 40, 40 For a more detailed showing of the clip tenters 40, 40, reference may be had to the Schreiner Patent 2,082,981 of June 8, 1937.
  • Rubber belt 42 having left the surface of the drum 46 thereupon passes over pulley rolls 48 and 49.
  • the shrunken webs 10 and 12 are now separated and passed over dryer drums 50 and 50 respectively, against which they are constrained by the action of felt bands or belts 52 and 52 respectively.
  • web 10 After passing around almost the entire periphery of the drum 50, web 10 is conveyed (by means of the rolls shown) to cart 56 wherein it is caused to be folded by action of member 55.
  • 57 and 57' denote the usual dryer drums for the felt belts 52, 52'.
  • web 12 after leaving shrinker 41 passes through the belt dryer 50 disposed above dryer 50, and is conveyed to cart 56' guided by member 55'.
  • FIGURE 2 The action of the rubber belt shrinker is more fully shown in FIGURE 2, wherein it will be noted that the outer surface of the belt 42 has been expanded while passing over roll 44. However, when the belt 42 makes the reverse curve around the heated drum 46, such outer surface necessarily contracts, and thereby causes a lengthwise compacting and shrinking of the webs 10 and 12.
  • Patent 2,721,370 For a more detailed though concise description of the manner of operation of this device, reference may be had to Patent 2,721,370 at column 7, third complete paragraph. It may be stated however, that the temperatures and pressures used for running the double plies through the machine are in nowise critical.
  • the property possessed by the textured fabrics compressively shrunk by my improved process of having the face thereof unpolished may further be utilized in the operation of machine cutting of garment or other pieces from a stack of fabric lengths so treated, which sometimes mounts to 400 or more layers. The entire stack is cut through by a suitable mechanically operated knife. Because of the fact that the unpolished surface of one layer is in contact with the back surface of the succeeding layer, a minimum disturbance of the layers results during the cutting operation.
  • the method which comprises simultaneously but separately feeding a pair of webs of said fabric in an endwise direction, conditioning said moving webs by the action of added moisture and heat to render plastic the fibers thereof, progressively tensioning the moving moisture conditioned webs widthwise to a selected common width,
  • a first moistening device A means for conveying a first single ply from a bulk supply to said moistening device A
