Definitions
- atension stable slub effect yarn can be obtained by supplying a first core yarn to a turbulence chamber, having yarn inlet and exit passage ways, under conditions of zero overfeed so that no bulk is inserted into the yarn, and injecting a second cffeet yarn under conditions of overfeed by the action of a fluid jet, the fluid being permitted to exhaust out of the inlet and exit passage ways of the turbulence cham bef, the combined yarn from the turbulence chamber then being forwarded through an intermingling jet and finally wound up in the form of a coherent slub effect yarn,
- the effect yarn becomes looped and entang gled and at random intervals becomes attached in the form of balls to the core yarn and is withdrawn with the core yarn from the turbulence chamber.
- the intermingling jet then firmly locks the effect yarn into the core natively it may be withdrawn from a supply package by the tension imparted by the wind-up apparatus and, optionally, ayarn tension device maybe employed above the turbulence chamber to assist in maintaining sufficie'nt tension in the yarn to avoid bulking.
- the exit passageway of the turbulence chamber isof smaller diameter than the inlet passageway.
- the inlet passageway may be restricted by a capor baffle at the entrance to confine yarn and fluid movement which could adversely affect the stability of the incoming core yarn.
- the effect yarn is injected into the turbulence chamber near to the junction of the inlet and. exit passageways.
- the effect yarn is preferably injected into the turbulence chamber in a direction perpendicular or substantially perpendicular to the forwarding direction of the core yarn.
- the nature of the slub effect yarn is affected by the positioning of the intermingler jet, the air pressure therein and in particular by the angle between the axis of the intermingler yarn passageway and the axis ofthe turbulence chamber yarn passageway. Increasing the amount of air exhausting from the intermingling jet and entering the outlet passageway of the turbulence chamber, i.e., decreasing the above angle, produces long thin slubs; decreasing the amount of air by increasing the angle produces short thick slubs.
- the nature of the slub effect yarn is also affected by the nature of the effect yarn and the extent of overfeed of said effect yarn. ln a preferred embodiment of the invention, the angle between the yarn emerging from the intermingler jet and the axis of the intermingler yarn passageway is at least 5 0.
- yarns which may be employed for either the feed yarn or the core yarn.
- Yarns of, for example, polyester, polyamide, rayon, acetate or acrylics may be employed as may yarns of naturally occurring fibres such as wool, cotton, etc.
- yarns may be bulked yarns, staple yarns or continuous filament yarns.
- the turbulence chamber has a core inlet passage way 5 and an outlet passageway 6.
- the inlet passageway may be of cylindrical, conical or square cross-section. It may be baffled or unbaffled and may be open or restricted at the entrance.
- the passage way has a step 7 (but this is not essential) such that the outlet passageway is of smaller diameter than the. inlet passage way.
- Below the turbulence chamber is an intermingler 8, a free running roller 9 and a guide 10 which is located above a conventional wind-up apparatus, not shown.
- effect yarn package 12 carrying effectyarn 11 is mounted opposite to the turbulence chamber 4 together with a guide l3'and an air disperser 14.
- the effect yarn is positively fed tothe air disperser through a pair of nip or feel rolls.
- a pair of feed rolls l5, 16 may be located between the core yarn package and the turbulence chamber.
- a steam heater 17 may be situated between the free running roller and the wind-up to give loop deformation and change the tactile properties of the yarn.
- EXAMPLE 1 Using the apparatus as illustrated in the. drawing; a 167 dtex, 30 filamentpolyester core yarn was passed through the turbulence chamber to the wind-up at a speed of SOOft/min and a 78 dtex, 20 filament nylon 66 effect yarn was injected through theair disperser l4 3 tached itself to the core yarn and the combined core and effect yarn then passed through the intermingler jet 8 around the free running roller to the wind-up.
- EXAM Pl sE 2 Theapparatus as illustrated in the drawing was used except that the effect yarn was positively fed to the air disperser 14 by a nip roll system with the disperser situated to inject the effect yarn into the upper portion of the turbulence chamber exit passageway and the pair of nip rolls 15, 16 was omitted.
- the process conditions were as follows: i
- Core yarn l 10 dexitex/48 filament po1y(ethy1ene terephthalate) yarn
- Effect yarn 84 decitex/36 filament poly(ethylene terephthalate yarn
- I Wind-up speed: 1 100 ft/min
- Overfeed 'of effect yarn ll5l25% Air pressureto disperserz5-l0 p.s.i.
- Air pressure to intermingler 70-80 p.s.i.
- the slub effect yarn so produced had a decitex of 245 and contained 45 and 55 wt percent of core and effect yarns respectively.
- a 1,000 metre length of the slub effect yarn contained 4,194 slubs of which 56 percent were of length between 1 to 2 cm, 37 percent were of length between 2 to 5 cm and 7 percent were of length between 5 to 10 cm.
- the slub effect yarn was particularly suitable for weft knitting outlets.
- a process for producing a tension stable slub effect yarn which comprises supplying a-first core yarn to a turbulence chamber, having yarn inlet and exit passage ways, under conditions of zero overfeed so that no bulk is inserted into the yarn, and injecting a second effect yarn under conditions of overfeed by the action of a fluid jet, the fluid being permitted to exhaust out of the inlet and exit passage ways of the turbulence chamber, t-hecombined yarn from the turbulence chamber then being forwarded through an intermingling jet and f1- nally wound up in the form of a coherent slub effect yarn.
