Abstract

The invention relates to the field of spinning, and discloses a warmth-retaining and wear-resisting nylon 6 pre-oriented yarn. The preparation method includes the first step of mixing, wherein polycaprolactam chips, heat insulation particles and wear-resisting functional masterbatch are mixed; the second step of melting, wherein the materials are subjected to heating and melting extrusion in a screw extruder; the third step of spinning, wherein the melted materials are spun in a spinning assembly, the product is jetted from a special-shaped spinneret plate to form a melt trickle, and after blast cooling, monofilaments are formed; the fourth step of oiling and bundling, wherein oiling and bundling are carried out at a nozzle to form bundles; the fifth step of pre-interlacing, wherein the bundles are subjected to pre-interlacing on a pre-interlacing device; the sixth step of winding, wherein the bundles are subjected to winding forming at a winding head. The warmth-retaining and wear-resisting nylon 6 pre-oriented yarn has the advantages of excellent warmth retaining performance, wear resistance and the like on the basis of maintaining original performance, and can be applied to some specific fields with high warmth retaining requirements and high wear resisting requirements.

Description

Technical field [0001] The invention relates to the field of spinning, in particular to a warm-keeping and wear-resistant nylon 6 pre-oriented yarn. Background technique [0002] Pre-oriented yarn refers to an incompletely stretched chemical fiber filament with an orientation degree between oriented yarn and drawn yarn obtained by high-speed spinning. Compared with undrawn yarn, it has a certain degree of orientation and stability. Well, it is often used as a special yarn for stretched false twisted textured yarn (DTY). Nylon 6 is one of the commonly used textile fibers. It has a series of excellent properties and is widely used in clothing, home textiles, decoration, agriculture, fishery and other fields. [0003] The Chinese patent with application number 201110432639.3 discloses a porous micro-denier nylon 6 pre-oriented yarn, its preparation process and its equipment. Add random copolymer additives of methacrylate, maleic anhydride and phenhexene in the screw melt extrusion s...
