Abstract

The invention discloses a method for preparing fishing flexible blended and modified polyethylene monofilaments, relates to a method for preparing fishing polyethylene monofilaments and aims to provide a method for preparing the fishing flexible blended and modified polyethylene monofilaments. A stirring machine, a single-screw extruder, a twice-drafting electrical heating drafting machine, a filament winding machine and a filament separating machine are adopted. The method is characterized by comprising the following steps of: mixing a sieved spinning-grade dry HDPE resin, a dry VERSIFYTM 6002 elastomer, white oil or a turpentine aid; uniformly mixing the materials to obtain an HDPE / VERSIFYTM 6002 elastomer blend and fusing and extruding the blend by using the single-screw extruder; cooling and pre-drafting fused and extruded primary filaments, thermally drafting the pre-drafted filaments twice, rapidly cooling the thermally-drafted filaments with high-pressure air current after the total drafting multiple is controlled to be between 9.63 and 9.87 times and winding modified PE monofilaments by using the winding machine; and separating the modified PE monofilaments into the fishing flexible blended and modified polyethylene monofilaments by using the filament separating machine.

Description

technical field

[0001] The invention relates to a method for preparing polyethylene monofilament for fishing in the technical field of aquatic products. Background technique

[0002] Polyethylene (PE) monofilament is one of the fishing fiber materials in the field of agricultural science and fishery technology. People have specific requirements for its strength, roundness, extensibility and softness. A new polyethylene monofilament material for fishing with moderate resistance and good cross-section roundness. In the existing aquatic technology field, the ordinary PE monofilament for fishing is improperly controlled in the monofilament production process, which may lead to poor roundness of the pre-drawn yarn, slow crystallization speed of the primary yarn, and low strength of the pre-drawn yarn, which will further affect The strength, feel and appearance of the monofilament and its downstream fishery material products; the existing common PE monofilament for fishing is mad...
