Definitions

  • the greige or the backgray receives color driven through the printed textile and receives the full amount of color emptied from those engraved areas which extend beyond the selvage of the goods.
  • Backgrays are usually as long as the piece of goods being printed. They are removed periodically from the printing range, color is discharged, the backgray is washed and then returned to the printing range. Washing progressively weakens the backgray fabric. Ultimately the backgray becomes scrimped, torn and unusable.
  • the yardage of printed goods that may befprinted on one yard of backgray varies enormously. Depending upon the pattern, weave and type of work that a printing establishment handles, the life of a backgray may range anywhere from a very small multiple of the yards of goods which were printed to possibly 200 times the yardage of the printed goods. In all cases, however, the initial cost of the backgray and the cost of maintaining it add considerably to the cost of the printing operation. However, the most serious ditiiculty associated with the use of backgrays occurs during cloth shortages, as during a national emergency, when many mills find it hard to obtain backgray cloth in sufiicient amounts.
  • wash blankets are water and color impermeable and therefore can be washed and dried quickly in a continuous operation. They are put on the printing machinein the form of a long loop or endless belt, with the goods to be printed lying directly upon the wash blanket as they travel through the printing station. The blanket then passes through a continuous Washer where the colorsmeared blanket is scrubbed by rotary brushes and rinsed by water sprays; then it passes through a continuous drier.
  • the blanket returns to the printing station in a clean, color receptive condition.
  • the wash blanket process has workedwell on a limited number of patterns where the design is light and the amount of color deposited on the blanket is small.
  • a smooth faced blanket does not work well when the amount of color deposited on the blanket is considerable, since the smooth face of rubber has very little capacity to pick up color.
  • wash blankets have been modified in various ways to increase the capacity of rubber faced blankets to carry color- Nevertheless, although wash blankets are widely used, there are still many designs and many fabrics which must be printed by the use of a backgray.
  • the present invention is concerned with an improvement in wash blankets which extends their range of usefulness to an extraordinary degree. In fact, on the printing machine on which these blankets were tested and on which a large variety of fabrics, designs and colors were printed, no design or fabric tested required the use of a backgray.
  • the, filament is a synthetic, linear high polymer
  • the crystals of the polymer are preferentially oriented along the fiber axis as a result of cold-drawing
  • the polymer possesses low to negligible water absorption
  • the softening point of the polymer is above the temperature used for curing the rubber and above the boiling point of water;
  • the yarn made from the filament also possesses elastic properties (although the elasticity of the yarn as contrasted with the high elasticity demanded of the filament may be in the same order as that possessed by some yarns spun from natural textile fibers);
  • the elastic cushioning layer of rubber in which the fabricsurface layer is bedded takes an active part in the series of happenings which have 'just been described.
  • the layer permits a relative movement of the individual filaments of the yarn when a rolling pressure is appliedyand second, its exerts an outwardly directed thrust on the yarn which forces the liquid from the lowermost capillary areas,
  • the fibers utilized'iri our invention do not form a filter mat and the color does' their interfilamentary space to a deleteriworking face on a tert'le print bauket is progressively.
  • the blanket is usually pa sed through squeeze rolls as the final step of the washing op .ration. Further drying of the blanket is normally necessary. This is accomplished bycarrying the blanket around the periphery of a few textile drying cans which are heated in the usual manner. By the time any given area of the blanket returns to the printing station, the original dry conditon of the yarn has been restored.
  • the speed at which a textile range equipped with such a blanket may be run is apparently set by the speed at which finishing operations may be conducted on the cloth. Some designs cannot be developed, dried and fin shed as fast as others. Top speed so far reported is 192 yards a minute for a 28-yard blanket, and at this speed a high quality print which was satisfactory in every respect was produced. In no case, to date, has the top speed of a textile range been limited by blanket condition.
  • a printer can produce high quality unflushed patterns without spending nearly as much time in the setting of the individual color rolls as was necessar'y in the past.
  • our improved textile blanket consists of a color absorptive working face adhered to an] elastic cushioning layer which in turn is secured to a body sand wich of several plies of duck coated with a rubbery interply cement.
  • the individual plies of the print blanket structure are respectively spliced according to any manner known in the art to form an endless belt, the splice in each ply being preferably offset from that of any other ply to increase the tensile strength of the blanket.
  • the entirev assembly is cured under heat and pressure preferably in.
  • the preferred means which we use to-prevent the penetration of therubber through the color absorpa tive working surface is to cause the elastic cushioning layer of rubber to set up or to recover to such a degree that it is no longer fiowable under the high pressure which is used in the cure of the blanket. porate a heat curing type of resin in the cushioning layer,
  • the first step is conducted by heating the blanket while applying such a low pressure that the rubber compound will not flow through the interstices of the weave.
  • the specific adhesion of the elastic cushioning layer to the synthetic linear polymer is not so high as when heat curing resins are used, but it is adequate for most purposes.
  • Textile print blankets perform two functions. Their surface layer carries away surplus color, but the blanket also acts as a power transmission belt. It drives the washer and frequently a considerable portion of the auxiliary apparatus in a printing range.
  • body construction of our print blankets forms no part of our present invention and that body constructions may vary greatly, depending upon the power transmission requirements of the printing range.
  • the example of the construction of the body sandwich which follows is one that has been found satisfactory for a wide range of requirements on printing machinery. It is set forth merely for the purpose of making the disclosure complete and is not to be considered as limiting the scope of the invention beyond that defined in the appended claims.
  • Rubber compounds used in the following examples make a tough, solvent resistant cushioning layer which has excellent adhesion to the body and to the working Interply cements produce a strong adherent bond.
  • Rubber technologists will, however, recognize that the formulae are illustrative and that a large number of rubbery compounds of alternative formulae and compounded with different techniques can be used with equivalent results. Additionally, the technologists will recognize that rubber may be cured throughout a very wide temperature range depending upon its specific formulation. Although we prefer to cure the blanket at 315 to 325 F. and at pressures of about 500 lbs.
  • weaves having a count of less than that equivalent to 30 x 30 in a 210/2 filament nylon will be so open that the specific absorptivity per square inch of the blanket will be reduced below that which appears to be required.
  • the condensation reaction product of hexamethylene diarnine and adipic acid is chemically distinct from polymeric acrylonitrile and that, in turn, is chemically distinct from the condensation product of a polycarboxylic acid and ethylene or other glycols, yet such chemical substances are operative.
  • Many more synthetic resins which are known would. likewise be operative if they were available as yarns or textiles.
  • the fabric forming the working layer be insoluble in the medium in which the color is suspended.
  • the greater proportion of the colors used in textile printing are suspended in water, and also most of the washing operations conducted on the blanket use water as the wash liquid alone. Therefore, in considering insolubility, commercially satisfactory results will be produced if the surface of the blanket is insoluble in Water.
  • a minor proportion of textile printing makes use of solvent solutions of a curing type resin emulsified in Water. It is advantageous to produce blankets which are resistant to the solvents which are used in the process, as well as to water.

  • the textile fabric which is chosen for the surface ply is composed of filaments which have a so-called dog bone cross section.
  • a dog bone filament often results when the filament is spun from a solventsolution. If the volume of the filament shrinks as they solvent dries, and after the surface of the filament has become fixed, a cross section of the filament which results may be described as a modified figure E or a dog lensqshaped, cross section and the filaments, rather than having a more or less random arrangement in the yarn, line themselves upat least on the outer surface of the yarnas shingles on a roof.
