  • the filaments chosen for preparation of the fabrics of this invention must comprise a plurality of components adhered together in substantially side-by-side relation. While three or more components may be employed if desired, for practical purposes twocomponent systems are preferred. The components may be present in various ratios relative to one another. T wo-component systems may, for instance, contain 20% of one component and 89% of the other, or various ratios, such as :58, 43:68, or 36176 may be employed.
  • the component having the higher shrinkage on heat setting have the higher denier so that the finer filaments will predominate in the surface of the fabric to give a soft hand while the heavier filaments on the interior contribute to resilience.
  • the splitting apart of the components to form separate filaments may be achieved in any desired manner, provided that the filaments are not xcessively damaged in the process. Suitable treatments involve lexing or mechanical worlc'ng of the filaments in the dry state or in the presence of liquids.
  • the preferred process is to treat the filaments with a hot aqueous solution while subjecting the fabric to vigorous agitation to flex the filaments.
  • the level of adhesion between the filament components is controlled so that the filaments remain adherent during yarn treatment and fabric preparation and separate upon being subjected to the desired conditions after the fabric is formed.
  • the aqueous solution may, optionally, contain various detergent soaps, emulsified solvents, etc., that may be desired to remove sizing or for other purposes.
  • suitable swelling agents for one or both of the components may be employed to aid in component separation.
  • suitable swelling agent for the particular polymeric system employed will be readily apparent to those skilled in the art. With a polyamide-polyester system, for instance, an aqueous solution of sodium phenylophenate is suitable. Also in such a system the average level of adhesion forces between the dry filament components of the same component filament is preferably at least about 13 g./cm.
  • the cohesion between the components in the filaments can conveniently be determined by cutting about 8 cm. lengths of the filaments, splitting the components apart at one end by lexing the end, or if necessary by immersing the end in a swelling agent for one of the components, e.g., a aqueous formic acid solution, attaching one of the split apart components to a sensitive strain gage and the other component end to a rod which is drawn away from the strain gage at a constant rate of 2.4 cum/min.
  • the force required to pull the components apart is recorded by an electronic recorder attached to the strain gage.
  • the strain gage employed was a Statham Instrument Company gage having a range of 0 to +0.15 oz.
  • the signal from the gage was fed to a preamplifier, then to an amplifier and finally to a conventional Sanborn recorder.
  • the rod to which one of the component ends was attached was heated in a horizontal position in a container of water by means of two corks.
  • a filament or strand of yarn was attached to one end of the rod and the other end of the yarn passed around a small motor driven roller to draw the rod away from the strain gage at a slow, constant rate of 2.4 era/min.
  • the length L of the interface between the adhered components of the composite filament is determined and the measured force, F, divided by this value. This length L measured on a photomicrograph taken at high magnification of a transverse cross section of the composite filament by rolling a map reader along the clearly visible line at the interface of the different components.
  • the composite filaments have the characteristic that they crimp when subjected to boiling water but subsequently split when subjected to sufficient levels of mechanical working or flexing.
  • the filaments which shrink to the lesser extent under these conditions having the characteristics that they shrink to a greater extent than the other filaments when heated to a temperature within about 20 to 30 C. of the softening point of the particular polymer.
  • the initial crimping in the hot solution results in a desirable bulking of the fabrics.
  • the filaments in the fabric which have the lower shrinkage on ⁇ heat setting should have the lower denier, the denier per filament of the lower denier filaments preferably beng no greater than about 1.6. For other eflects, higher deniersrnay be used.
  • Another advantage of considerable interest of the fabrics of this invention is that they exhibit a subdued non-synthetic luster and good cover without the use of a delustering agent in the fiber, although delustered fibers may be used to enhance this eifect if desired.
  • Another advantage of the present invention is that fabrics containing sharp edged filaments are obtained. This contributes significantly .to the silk like character of the yam and fabric.
  • Various cross-sectional shapes in the original composite filament as shown in FIGURES 9-14 may be employed to give, on separation into its component, sharp edged filament.
  • the sharp edge in order to contribute to the silk-like properties is defined by two longitudinally extending filament surfaces intersecting in an acute angle sigrificzmtly less than 90.
  • Such filaments cannot be obtained directly by extrusion since the polymer or polymer solution employed tends to assume a circular cross section and, even though the shape may be varied considerably, sharp edged filaments cannot be produced by this means.
  • laments with round cross sections may be split into semi-circular cross sections having sharp edges or a round cross section may be split into an ellipse and a crescent depending on the configuration of the orifices used in the extrusion.
  • Filaments having substantially rectangular shape may be split into two genermly triangular shapes having the desired sharp edges or other shapes as desired.
  • Various other shapes may be used in the original composite filaments to obtain filaments of various cross-sectional shapes in the final fabric.
