A yarn object which, even though made of ultra-high-molecular-weight polyethylene, can be satisfactorily prevented from color fading caused by contact with other objects or the like, can be produced easily at low cast, and can maintain high strength. The yarn object is colored with a colorant. The yarn object includes a core yarn 2 colored with a predetermined colorant and an outer-layer yarn 3 disposed on the periphery of the core yarn. The outer-layer yarn 3 is disposed in such a manner that the core yarn 2 is prevented from contacting with other objects. The outer-layer yarn 3 includes a transparent filament and a space 4 is formed between the outer-layer yarns 3. The color applied to the core yarn 2 is externally visible through the transparent outer-layer yarn 3 and the space therebetween 4.

A process for producing a tapered multifilament yarn comprising feeding a drawable filament to a drawing apparatus and changing the take-over speed relative to the feed speed of the filament in order to change the thickness of the filament in a longitudinal direction, characterized by making the take-over speed slower than the feed speed under heating in a part of the filament in the longitudinal direction and thereby shrinking and thickening the part of the filament. According to the process, the ratio of the thickness of the thickest part of the tapered multifilament yarn to the thickness of the thinnest part thereof can be easily increased.

COLORED YARN OBJECT, PROCESS FOR PRODUCING THE SAME, AND FISHING LINE
A colored yarn object which, even when made of ultrahigh-molecular polyethylene, can be satisfactorily prevented from suffering crocking caused by, e.g., contact with other object, and which can be easily produced at low cost and can retain high strength. The yarn object has been colored with a colorant. It comprises a core yarn (2) colored with a given colorant and an outer-layer yarn (3) disposed on the periphery thereof. The outer-layer yarn (3) is disposed so as to prevent the core yarn (2) from coming into contact with other object. The outer-layer yarn (3) comprises a transparent filament and is disposed so as to leave a space (4) between adjacent parts of the outer-layer yarn (3). The color imparted to the core yarn (2) can be seen externally through the transparent outer-layer yarn (3) and the space (4).
A process for producing a tapered multifilament yarn which comprises feeding a stretchable filament to a drawing apparatus and changing the takeoff speed relative to the feeding speed to thereby change the thickness of this filament in the lengthwise direction. The process, which is for easily and efficiently producing a tapered multifilament yarn, is characterized in that in lengthwise-direction part of the filament, the speed of takeoff with heating is made slower than the feeding speed to thereby shrink and thicken the part of this filament. Thus, the proportion of the thickness of the thickest part of a tapered multifilament yarn to the thickness of the thinnest part thereof can be easily made high.

An object of the present invention is to provide a method of manufacturing autohesion thread such that a smooth surface is offered, the cutting thereof is easy, filaments composing thread are not frayed in cutting, and additionally drainability are superior, and then plural kinds of filaments can be combined. The invention provides a method of manufacturing a line of fusion thread characterized in that plural filaments comprising thermoplastic resin are paralleled, twisted and/or braided if desired, and subsequently drawn under heating at a draw ratio of less than 1.0 to thereby substantially fuse the adjacent filaments to be subsequently drawn under heating at a draw ratio of more than 1Ø
