Embodiment Construction

[0018] An embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0019] Adopt the spinning process flow shown in Figure 1, the first step of spinning: the polypropylene particles with a melt index of 2-4g / 10min enter the feed port 1 on the screw extruder 2 by their own weight from the feed hopper, Screw pressure is 80kgf / cm 2 , due to the rotation of the screw, the polypropylene particles move forward along the screw groove, and a heating element is installed on the outer periphery of the screw sleeve; the heating temperature of the screw extruder 2 where the polypropylene particles are located from the feeding section to the discharging section is: 1 Zone (feed section) 240°C, Zone 2 280°C, Zone 3 280°C, Zone 4 280°C, Zone 5 285°C, Zone 6 285°C, Elbow 280°C, Flange 280°C; heat transfer through the sleeve For polypropylene particles, the polypropylene particles are heated and melted and then compressed and extruded by the ...

Abstract

The invention relates to a production method of superfine polypropylene composite fully-drawn wallpaper fiber. The method is characterized in comprising the following steps of: (1) melting polypropylene grain under high temperature, wherein the draw ratio of a spray head is 30-40; (2) cooling by means of lateral air blowing, wherein the air quantity is 750-850NM3 / chroneme, the wind speed is 0.1-0.3m / s, and the wind temperature is 12-16 DEG C; (3) winding after oiling through a lower wire guide pan, an upper wire guide pan and a friction roller, wherein the winding speed of a spinning wind is 850-950m / min, and winding to be a winding spindle; (4) shaping in a drawing way: statically balancing the winding spindle for 4-6h, and shaping in a drawing way through a first heat pan, a contact type heat pan, a second heating pan and a cold pan, wherein the drawing multiple is 4-6 times, the feeding speed is 40-50m / min, and the winding speed of the winding spindle is 180-220m / min; and (5) cutting off and bagging. The preparation method effectively overcomes the rigidity of the normal polypropylene filament yarn, leads the polypropylene filament yarn to have good rebound resilience and soft handle feel, and leads each performance index of the product to meet the requirement of the material of the wallpaper.

Description

Technical field: [0001] The invention relates to a production method of polypropylene fiber, in particular to a production method of ultrafine polypropylene composite fully drawn wall covering fiber. Background technique: [0002] The existing polypropylene filament 667dtex / 110f used for wall covering materials not only has low breaking strength, but also has a hard monofilament. The breaking strength after testing is 3.5-4.4cN / dtex. Because the monofilament is hard, it cannot be well bonded with other wall covering materials during use, and it is easy to expose the wall surface, so it cannot meet the requirements of wall covering materials. Contents of the invention [0003] The purpose of the present invention is to provide a kind of ultra-fine polypropylene composite full-drawing that can overcome the above-mentioned shortcomings of the prior art, can make polypropylene filaments have excellent resilience and soft feel, and can meet the requirements of wall covering mat...
