Definitions
- This invention relates generally to a technique for making a fiat fabric, and more particularly to a continuous process wherein a web of synthetic material is converted into ribbon-like yarns which are supplied directly into a weaving loom to produce a flat fabric.
- the conventional technique for producing ribbon-like, synthetic yarns to be Woven into a flat fabric involves extruding the synthetic material into a web which is oriented and slit into individual ribbons. These ribbons are then Wound on a beam for use as warp yarns or onto suitable packages for use as filling yarns. In weaving operations, the ribbon yarns are thereafter unwound from the beam and the packages.
- existing techniques involve discontinuous winding and unwinding operations, as well as transfer operations which add materially to the over-all cost of production.
- a significant feature of the invention is that it eliminates such conventional operations as packaging and 3,503,106 Patented Mar. 31, 1970 p CC beaming, thereby effecting significant production economies.
- Another object of the invention is to provide a continuous technique of the above type in which the folding serves to conceal the cut edges of the strips, thereby facilitating proper weaving operations, the folding serving to improve the edge tear-strength and hence the tear values of the resultant fabric.
- an object of the invention is to provide a low-cost, sheet-like woven fabric whose structural characteristics are superior to those heretofore produced at higher cost.
- thermoplastic material such as polypropylene
- molten thermoplastic material such as polypropylene
- FIG. 1 schematically shows a system for carrying out a continuous technique for producing a sheet-like woven fabric in accordance with the invention
- FIG. 2 is a perspective view of one of the folding units
- FIG. 3 is a side view of the folding unit and of the associated calender rolls.
- FIG. 4 is a transverse section taken through a ribbon produced by folding a strip.
- FIG. 5 is a plan view of the sheet-like fabric produced by the weaving operation.
- the raw material used to make fabric in accordance with the invention may be any known form of molecularly orientatable, thermoplastic polymeric material such as polyethylene, polypropylene, polyamide, polyester.
- Polymers are synthetic substances composed of large molecules that have been formed by the union of a group of single molecules with one another.
- the selected raw material is rendered molten and extruded through a suitable extruder assembly 10 to form a film-like web 11.
- a suitable extruder assembly 10 to form a film-like web 11.
- the manner in which the raw material is converted into Web-form is entirely conventional, and any standard equipment may be used for this purpose.
- Web 11 is pulled from extruder 10- by feed rolls 12, the Web being cooled before it reaches these rolls, so that it is below its softening point. Longitudinal orientation is then effected by the process of drawing to irreversibly stretch the web and thereby increase its tensile strength considerably. This is accomplished by cooled draw rolls 13, the peripheral speed of which is greater than that of heated feed rolls 12, the ratio between the two rolls being termed the draw ratio.
- the stretch-oriented web 14 emerging from draw rolls 13 is conveyed into a slitter mechanism 15 Where it is divided by rotary blades or equivalent means into a multiplicity of individual flat strips S to S Alternatively, slitting may be effected prior to orientation. Because orientation imparts to the material a tendency to fibrillate at the edges when subjected to stresses, strips S to S emerging from the slitter have somewhat rough edges containing fine fibrils.
- Each strip is conveyed through a folding unit (F to P which, as shown separately in FIG. 2, may take the form of a conical sleeve 16 having a tapered bore 17 therein with an oblong cross-section of progressively diminishing dimensions.
- a folding unit F to P which, as shown separately in FIG. 2, may take the form of a conical sleeve 16 having a tapered bore 17 therein with an oblong cross-section of progressively diminishing dimensions.
- the folded-over edges are pressed down by calender rolls 18, as shown separately in FIG. 3, to form fiat and relatively narrow ribbons R and R,,, the creased edges of the ribbons being the folded-over edges of the strip.
- the creased edges of the ribbon present a smooth surface.
- the width of the strip is such that when folded over as described above, the resultant ribbon constitutes a yarn of the desired denier.
- Ribbons R to R are then fed into a standard loom 19 for weaving man-made yarns, such a Draper loom, the ribbons being interwoven to form a fabric having a flat surface, as shown in FIG. 5.
- a standard loom 19 for weaving man-made yarns, such a Draper loom, the ribbons being interwoven to form a fabric having a flat surface, as shown in FIG. 5.
- the strips are made in a one-mil thickness to produce folded-over ribbons or flat yarn of two-mil thickness.
- a continuous technique for producing a flat fabric comprising the steps of:
