Abstract
Method to continuously merge two multifilament yarns supplied from bobbins on a creel by merging and entangling the two yarns in a commingling air jet and supplying directly to a warper to form a warp beam. The method includes feed rolls upstream and downstream of the air jets providing an overfeed of the yarns to the jet of about 2.3%.
Description
21 ~7067 CONTINUOUS PROCESS TO PROVIDE A HEATHER YARN
This invention relates generally to the continuous production of a warp beam of a multiplicity of merged or entangled yarns from a plurality of bobbins mounted in a 5 creel.
It is known to air entangle a multiplicity of yarns from a bobbin into a single yarn and then take up the merged or entangled on another bobbin which is combined with other bobbins and supplied to a warp beam. The supplied yarns can be yarns of the same color or texture or can be yarns of di~l~-ll colors. These yarns normally are 10 taken up on a bobbin prior to warping and require the additional step or steps of loading them onto a creel and then threading them up to a warper to provide a warp beam of such yarns.
It is therefore an object of this invention to provide a continuous process of merging a plurality of yarns from bobbins mounted on a creel and, in line, continuously 15 directing the merged yarns on a warp beam.
Other objects and advantages of the invention will become clearly apparent as the specification proceeds to describe the invention with reference to the accompanying drawing, in which:
Figure 1 is a side schematic view of the new and hllpl()ved process and Figure 2 2 0 is a top view taken on line 2-2 of Figure 1.
Looking now to the drawings, the reference numbers 10 and 12 represent a false twisted single ply, 250 denier, 100 fil~ment polyester yarns that are being supplied from bobbins 13 on a creel 14. In the prerelled form of the invention, the yarn 10 is light grey and the yarn 1 2 is a dark grey in order to form a heather yarn 18 but it should be ~1 ~37067 understood that other synthetic filament yarns, such as nylon, of di~erellL deniers, numbers of filaments and colors can be used within the scope of the invention.
The yarns 10 and 12 are delivered from the creel 14 to feed rolls 20 and 21 through a comb 22 which supplies one yarn 10 and one yarn 12 to each air entanglement 5 jet 24 mounted on the air manifold 26 supplying air to each air jet 24 so that they operate.at a pressure between 30 - 90 psi, preferably 60 psi, to entangle each pair of yarns 10 and 12. Since the yarns 10 and 12 are di~ele"l colors, the entangled yarn 18 has a heather appearance and is basically a two ply, 250 denier, 200 fil~ment yarn. To allow the jets 24 to provide this heather effect, the output feed rolls 30 and 32 are 1 0 supplying yarn to the warper 34 at a rate of 400 meters/minute which the input feed rolls are supplying yarn at a rate of about 409 meters providing an overfeed of yarn of about 2.3%. This overfeed can vary between 1 and 4 %. Prior to the output rolls 30 and 32 the entangled yarns 18 each pass through a separate space in the dent 36 to m~int~in them separate as the feed rolls 30 and 32 feed them to the warp beam 38 of the 1 5 warper 34.
The above described process provides an entangled yarn, preferably a heather yarn, warped and ready for use in a single continuous process from bobbins to the warp beam çli~in~ g the intermediate steps of winding bobbins and recreeling at the warper to form a warp beam. Furthermore, the continuous system described provides a yarn 2 0 having a heather hand and appearance especially when knit or woven into a fabric.
It is contemplated that modifications of the process can be made without departing from the scope or spirit of the invention and it is desired to be limited only by the scope of the claims.
