Filed Apr. 4, 1960, Ser. No. 23,872 4 Claims. (Cl. 28--59.5)
The invention relates to a method of and apparatus for continuous finishing of viscose yarn for use in manufacturing imitation Persian lamb cloth.
The hereinafter described method of continuous finishing of viscose yarn for use in manufacturing imitation Persian lamb cloth ensures improved quality of the resulting products.
The proposed method is characterized in that the yarn is impregnated with a well known solution used for fabric impregnation consisting of melamine-ureaformaldehyde condensate and a water repellent preparation with subsequent squeezing and drying and an additional stretching of the impregnated threads after squeezing.
The apparatus for carrying out the aforementioned process comprises the following interrelated elements and assemblies disposed in a line to provide a continuous operation: the yarn supply reel, the impregnating trough, the squeezing mechanisms, rolls for stretching the yarn, heated drier rolls and an automatic device for distributing the yarn on a winding reel.
Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing wherein:
The single FIGURE of the drawing is a diagrammatic view showing the apparatus of this invention.
The apparatus may comprise an axle 1 with catch 2 at the end, designed for rotatably supporting the yarn advancing reel 3, the impregnating trough 4 with the mixture of melamine-urea-formaldehyde condensate and water repellent preparation, the squeezing arrangement, the yarn stretcher rolls 5 and 6, the heated drier rolls 7 and 8 and the automatic device for distributing yarn on the Winding reel 9, the latter being located on the axle 10' posi tively rotated by suitable drive means, it being noted that the viscose yarn passes over suitable guide pins, disposed above and inside the trough or container 4.
The yarn squeezing device, installed adjacent and following the trough 4 is made in form of a bracket (not shown in the drawing) supporting two parallel plates 11 and 12 provided with opposed yieldable surfaces. Plate 11 is stationary, while plate 12 is spring-loaded for movement toward plate 11 and is fixed on the bracket by means of two screws 13 with adjusting nuts 14. The degree of squeezing is proportional to the tensioning of springs 15.
The yarn stretcher rolls 5 and 6 are positively rotated by suitable drive means, their circumferential speed being 15% less than the speed of the heated drier rolls 7 and 8. The rolls 7 and 8 are duralumin cylinders with inserted pins for bearings. Along the roll axles are disposed electric heaters or the rolls may if desired be steam heated.
The rolls 7 and 8 are disposed in one vertical plane, one roll having a horizontal axle and the other roll having its axle inclined at an adjustable angle to the axle of the first roll; this angle of axle inclination determines the pitch between the coils of the thread wound over both rolls drivingly connected by a continuous chain and rotated from the machine drive means.
The yarn dried and subjected to thermal processing upon the rolls 7 and 3, is advanced to the winding reel 9 "ice through the yarn guide 16 connected with the nut of the automatic yarn distributing mechanism. This nut engages a lead screw which continuously rotates in the same direction and is provided with rightand left-hand threads, ensuring the reciprocating motion of the nut and guide along the screw.
The characteristic feature of the proposed process of continuous finishing of viscose yarn for the manufacturing of imitation Persian lamb cloth is the operation of stretching of impregnated threads by means of rolls 5 and 6, as this operation ensures uniform mechanical properties of viscose yarn and consequently a good resistance of the imitation fur to degradation by weathering and mechanical action.
It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended claims.
What is claimed is:
1. An apparatus for the continuous finishing of yarn comprising a rotatably mounted reel for a supply of yarn, an impregnating trough containing an impregnating liquid composed of melamine-ureaformaldehyde condensate and a water repellent, said yarn passing from said reel through said trough, squeezing means engaging the yarn emerging from said trough to facilitate impregnation and remove excess liquid therefrom, a pair of spaced driven stretching rolls over which said yarn passes from said squeezing means, a pair of spaced drying rolls disposed in a common plane with the axis of one roll inclined with respect to the axis of the other roll, means for heating said drying rolls, said yarn passing from said stretching rolls over said drying rolls in a series of spirally disposed convolutions, a reciprocating yarn guide and a driven yarn receiving reel, said yarn passing from said drying rolls through said guide and onto said receiving reel.
2. An apparatus as defined in claim 1 in which said squeezing means comprises a pair of parallel opposed plates, yieldable opposed yarn engaging surfaces on said plates and adjustable compression spring means for urging one plate toward the other.
3. An apparatus as defined in claim 1 in which said yarn guide is reciprocated by a nut threadedly engaging 'a driven lead screw having right and left hand threads.
4. An apparatus for the continuous finishing of yarn comprising a rotatably mounted reel for a supply of yarn, an impregnating trough containing an impregnating liquid composed of melamine-ureaformaldehyde condensate and a water repellent, said yarn passing from said reel through said trough, squeezing means engaging the yarn emerging from said trough to facilitate impregnation and remove excess liquid therefrom, a pair of spaced driven stretching rolls over which said yarn passes from said squeezing means, a pair of spaced drying rolls disposed in a common plane with the axis of one roll inclined with respect to the axis of the other roll, means for heating said drying rolls, said yarn passing from said stretching rolls over said drying rolls in a series of spirally disposed convolutions and a driven yarn receiving reel, said yarn passing from said drying rolls onto said receiving reel.
