Embodiment 1

[0024] A two-component spun-bonded nonwoven fabric and a production method thereof, comprising the following steps:

[0025] (1) The slices of component PE and component PP with a melting point of 145°C were screened at a ratio of 1:1, and then dried and balanced at a vacuum of 45Pa and a temperature of 75°C for 35 hours;

[0026] (2) Heat and melt PE and PP polymers in a screw extruder at a temperature of 150°C. After melting, enter the melt filter to filter out impurities in the melt, and then calculate according to requirements. Enter metering pump and weigh, pressure 10Mpa after filtration, spinning system heat medium temperature 250 DEG C;

[0027] (3) The melt through the extruder is extruded from the spinning hole into the air, and while the thin stream of melt is cooled in the air, it is stretched at a certain speed to become thinner and longer. At this stage, the polymer melt is refined Simultaneous solidification, the fiber web is initially formed, and the pre-setti...

Abstract

The invention provides a production method of double-component spun-bonded non-woven fabrics. Double-component PP / PE filaments are adopted and are processed through slicing, filtration, hot air drying, heating and melting, positive pressure stretching, slitting and package and other processes, fiber filaments are externally loose and curled and are internally tightened and straight after deformation and have fluffy and stereochemical structures. Compared with common filaments, the original high strength, abrasion resistance and other excellent properties of fibers are kept, the structures and morphology similar to silk fiber flocculi are obtained, especially the filaments have excellent elasticity, few hairiness, good anti-pilling properties and high in firmness, web forming is uniform, gram weight can be up to 9 G, the width can be up to 3.2 M, and the pulling strength is longitudinally greater than 18 N and is transversely greater than 9 N.

Description

technical field [0001] The invention relates to a production method of a two-component spun-bonded nonwoven fabric. Background technique [0002] In the field of textile synthetic fibers, bi-component fibers are also called composite fibers. It is the melt or concentrated solution of two fiber-forming polymers, which are respectively input into the same spinning fiber according to the differences in components, proportions, viscosities or varieties. The filament components are merged at the appropriate part of the component and sprayed out in the same spinning hole to form a fiber, so that two kinds of polymers can exist on the same infinitely long fiber at the same time, which is called bicomponent fiber. Common structural forms are: skin-core type, side-by-side type, island-in-the-sea type, and orange segment type. [0003] Bi-component fibers are mostly produced by wet method, for example, they can be made into permanently crimped acrylic composite fibers. Wet spinning...
