難しく、第３図に示すノズルが好ましい結果を与える。The spunlike yarn of the present invention can be obtained, for example, by the following method. FIG. 2 schematically shows an example of an apparatus for obtaining a high-strength spunlike yarn of the present invention. The core yarn 1 and the side yarn 2 are fed by feed rollers R+ and R2, respectively. Depending on the overfeed rate R2Δ1 of the side yarn, a difference occurs in the size of loops, curls, or fuzz. A preferred overfeed rate is 1.05 to 1.5. N is used for air processing nozzles, and entanglement may be improved by applying a fluid such as water to the core yarn before entering the nozzle. Although it is possible to use a known air processing nozzle, since the molten liquid crystal polymer fibers have a very high initial elastic modulus and are hard, it is difficult to entangle them, so the nozzle shown in FIG. 3 gives preferable results.

q/cdG. It is preferable to change the direction of the yarn path using the guide G after it comes out of the nozzle, since the length of the loop can be reduced. A high-strength spunlike yarn having fluff on the surface of the yarn can be obtained by bringing a friction element rotating between the guide G and the take-up roller R5 into contact with the yarn and cutting the loop.
