Embodiment 1

[0033] Equipment: TE34×34 co-rotating intermeshing twin-screw mixing extruder, manufactured by the Ministry of Machinery Industry, Extrusion Machinery Research Institute, screw diameter: 34mm, aspect ratio: 28L / D, screw speed: 30-300rpm.

[0034] Keep polypropylene chips, polyamide, copolyester and PP-g-MAH in a vacuum oven at 80°C for 2h, raise the temperature to 120°C and keep vacuum drying for 4h, then blend and extrude on a twin-screw extruder, and cut grain. The twin-screw extruder has seven temperature control zones, the operating temperature of the screw zone is 180°C, 240°C, 240°C, 240°C, 240°C, the melt is 245°C, and the head is 245°C.

[0035] Among them: polypropylene (PP) adopts Y2600 (MFI=24.8, Tm=172°C, provided by Shanghai Petrochemical Plastics Division); polyamide chip (Tm=225°C, industrial grade, special material for high-speed spinning, provided by Yueyang Petrochemical); The polyesters are copolyester chips containing sulfonic acid groups (intrinsic viscos...

Embodiment 2

[0041] Adopt the same industrial conditions as in Example 1, wherein: polypropylene 90%, polyamide 4%, copolyester 3%, PP-g-MAH 3%. The volume specific resistance is 8.8×10 8 (Ω·cm). The relative strength is 1.65 (cN / dtex). The highest spinning speed is 3600m / min.

Embodiment 3

[0043] Dye solution formula: dye 2% owf, acetic acid 5% owf, ammonium acetate 5% owf, liquor ratio 1:100

[0044] The acetic acid / ammonium acetate in the dye solution is used as a buffer to adjust the pH value of the dye solution, and the pH value of the dye solution is controlled at about 4-5 during dyeing.

Abstract

The invention relates to a static electricity resistant coatable multifunctional polypropylene fiber and its preparing method. Its components and weight percentage includes: polypropylene 80-95%, copolyester 1-10%,maleic anhydride graft polypropylene 5-4% polyamide 2-6%. The static electricity resistant coatable multifunctional polypropylene has good fiber mechanical behavior with spinning speed higher than 3600m / min, the quarternary mixed modified fiber has higher coating rating and static electricity resistance.

Description

technical field [0001] The invention relates to a polypropylene fiber, in particular to an antistatic dyeable polypropylene fiber. Background technique [0002] Polypropylene, also known as polypropylene fiber, is a new fiber variety that began to be industrialized in the 1960s. Isotactic polypropylene was first successfully developed by Italian chemist Giulio Natta and others. Polypropylene fiber is the lightest fiber in synthetic fibers, 40% lighter than cotton and 30% lighter than polyester fiber, and can float in water. It has light weight, good warmth retention, stain resistance, mildew resistance, high strength and good wear resistance. Moreover, properties such as chemical corrosion resistance are very attractive to the textile industry. In 1957, the Italian Montecatini company realized the industrial production of polypropylene fibers using Ziegler-Natta catalysts. Due to its rich sources of raw materials, simple production process, low cost, and excellent propert...
