MGNAMARA 2 Sheets-Sheet 2 METHOD AND APPARATUS FOR MAKING TEXTURED FABRICS Robert J. McNamara, Folsom, Pa., assignor to Joseph Bancroft & Sons (10., Wilmington, Del., a corporation of Delaware Filed Nov. 22, 1961, Ser. No. 154,186 Claims. (Cl. 28-1) This invention relates to a method and apparatus for making a textured fabric and more particularly to a method of forming bulked and flat areas in a predetermined pattern in a knitted or woven fabric.
An object is to provide a novel and improved method and apparatus of the above type.
Another object is to provide a method of treating a crimped yarn during weaving or knitting so as to produce the above textured effect.
More specifically the invention applies to a method of weaving or knitting wherein a yarn sheet is taken from a warp beam and fed into the loom or knitting machine for fabrication. If the yarn on the beam is of the type which has been previously crimped and wound under tension on the cop or beam the yarn is in a temporarily straight form wherein the crimp has been straightened out but will be restored when the yarn is relaxed during fabrication.
The invention is based upon the fact that the crimp may be permanently removed from the yarn by subjecting the yarn, while in the straight form, to setting conditions. Accordingly heat is applied by a pattern roll or the like to selected positions of the yarn sheet as it is fed from the warp beam to the loom or knitting machine. When the yarn is relaxed after fabrication the crimp will be restored only to the areas which have not been heated by the pattern roll and a patterned or textured eifect is obtained.
United States Patent 0 The nature of the invention will be better understood from the following description, taken in connection with the accompanying drawings in which a specific embodiment has been set forth for purposes of illustration.
In the drawings:
FIG. 1 is a plan view of a portion of a fabric embodying the invention;
FIG. 2 is a partial section taken on the line 2-2 of FIG. 1;
FIG. 3 is a vertical, longitudinal section taken on'the line 3-3 of FIG. 4 illustrating one type of apparatus for making the product of FIG. 1; and I FIG. 4 is a horizontal section taken on the line 44 of FIG. 3.
Referring to the drawings more in detail the invention is shown as embodied in apparatus comprising upper and lower warp beams 10 and 11 respectively carrying warp sheets 12 and 13 respectively of the type commonly used in warp knitting machines of the tricot type as shown for example in the Young Patent 2,476,344, dated July 19, 1949.
The warp 12 is of the crimped type such as nylon continuous filament yarn which has been crimped in a stuifer crimper and wound on a cop or beam under a tension to substantially remove the crimp and leave the yarn in straight condition. However the crimp will be restored by heating the yarn in tensionless state after weaving or knitting.
In accordance with this invention the warp sheet 12 while still in the straight state is passed over a guide rod 14 in a downwardly inclined direction over a series of cam faces 15 carried by earns 16 which are mounted eccentrically on a cam shaft 17. The cams 16 may be individuallyadjusted about the shaft 17 and fixed in place 3,096,559 Patented July 9, 1963 by set screws 18. Each cam face 15 is of a width to engage a plurality of the warp yarns 12 so as to elevate such yarns at a selected point during the rotation of the shaft 17.
A shoe 20 which may be heated by suitable means such as resistance rod 21 is positioned above the yarn sheet 12 adjacent the cam faces 15 and in a position to be engaged by the yarns as they areelevated by the cam faces. The cam shaft 17 is mounted on an adjustable bracket 22 for varying its position with respect to the warp sheet.
The shoe 20 is mounted on brackets 23 from which it is heat insulated by pads 24. The brackets 23 are apertured for adjustment purposes, and are mounted on a rod 25 which is adjustably mounted in clamping bars 26. The yarn sheet 12 then passes under a guide rod 27 and over a tension rod 28 which is mounted on a pivoted arm 29. From the tension rod 28 the yarn sheet passes to a fabricating station shown as a knitting or weaving machine 30 such as a tricot knitting machine as disclosed in the Young patent above referred to.
The warp sheet 13 passes over a rod 31 to the machine 30 where it is woven or knitted with the yarns 12 to form a knitted or woven product.
In the operation of this apparatus the yarn 12 is heated when it is pressed against the shoe 20 by the cams 16. Since the yarn is held under tension during this heating it becomes set in straight condition and the crimp in this portion of the yarn is permanently removed. The crimp in the portions of the yarn which are not thus heated, however, will be restored when the fabric is heated and relaxed after fabrication.
By arranging the earns 16 in a predetermined manner a pattern effect may be obtained. In the embodiment shown the cams are alternated and displaced by so as to produce a checkerboard effect as shown in FIG. 1. In this figure the flat areas 41 correspond to the areas in which the yarns have been heated by the shoe and the bulked areas 42 represent the areas where the crimp has been retained. This patterned, textured effect can be varied as desired by suitable setting of the cams 16.
While the invention has been shown as adapted for use with a tricot knitting machine using a pair of warp beams it may also be applied to the warp beam of a loom for obtaining a similar effect.
Whatis claimed is:
1. The method of making a textured fabric which comprises feeding a sheet of crimped yarn to a fabricating station under a tension to substantially remove the crimp, applying heat to selected parts of said yarn sheet in a predetermined pattern to produce a permanent straight set in the heated potrions of the yarns, fabricating said yarn sheet into a fabric and heat-treating said fabric to relax the yarns and to restore the crimp to said yarns except in the areas of said straight set yarns whereby a patterned textured effect is obtained.
2. The method set forth in claim 1 in which said yarn sheet is passed in heat exchange relationship with a heated pattern member adapted to apply heat to selected areas of said sheet.
3. Apparatus for making a textured fabric comprising a warp beam carrying a set of crimped yarns, means feeding a sheet of said yarns from said beam to a fabricating machine, a heating shoe positioned along and normally out of contact with said yarn sheet, a pattern member adapted to raise selected yarns of said sheet into contact with said shoe for heating the yarns to permanently set the yarn in straight form in the heated areas.
4. Apparatus as set forth in claim 3 in which said pattern member comprises a series of cams disposed along the path of said yarn, and means mounting said cams for adjustment for varying the pattern effect.
3 5. Apparatus as set forth in claim 3 in which said 2,953,116 pattern member comprises a rotating member having 3,009,312 raised areas adapted to contact and raise said yarns into 3,034,196 contact with said heating shoe.
