Embodiment Construction

[0037] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, first, 0.01-2wt% of erucamide, 5-15wt% of polyethylene glycol and 40-80wt% of polypropylene are melt-blended and modified by a screw granulator to prepare polymer particles, and then the The polymer particles are blended with the polyolefin elastic copolymer and ultra-high molecular weight polyethylene chips; the preferred screw granulator has 5 heating zones, the aspect ratio is 30, and the temperature in the first zone is 160-190°C , the temperature in the second zone is 180-210°C, the temperature in the third zone is 200-230°C, the temperature in the fourth zone is 230-250°C, and the temperature in the fifth zone is 240-260°C.

[0039] Thereafter, the polymer melt is fed into the spunbond forming system to form a polypropylene-based filament web 1, and then the pre-fixed web, pre-wet, first-stage hot drawi...

Abstract

The invention relates to a polypropylene-based filament elastic super-soft non-woven material and a production method thereof. The production method of the polypropylene-based filament elastic super-soft non-woven material comprises the following steps: (1) elastic and super-soft blending modification of a thermoplastic copolymer: carrying out melt blending modification on 40 to 80 weight percentof polypropylene with 0.01 to 2 weight percent of erucyl amide and 5 to 15 weight percent of polyethylene glycol by using a screw pelletizer, thus preparing polymer particles; blending the polymer particles with 18 to 40 weight percent of polyolefin elastic copolymer and 8 to 12 weight percent of UHMWPE (Ultra-high Molecular Weight Polyethylene) slice; (2) spun-bond forming of a polypropylene-based filament net; (3) hot rolling and pre-curing of the polypropylene-based filament net; (4) pre-wetting; (5) first-stage hot drawing; (6) secondary forming through hot rolling; (7) second-stage hot drawing; (8) cooling; (9) coiling. The polypropylene-based filament net prepared by the invention is relatively excellent in elasticity, softness and fluffiness, does not contain substances having adverse effects on a human body and is safe to use.

Description

technical field [0001] The invention relates to a polypropylene-based filament elastic supersoft nonwoven material and a production method thereof. Background technique [0002] Polypropylene-based filament nonwoven material, as a filament fiber material with polypropylene polymer as the main raw material and melt spunbonding method as the processing method, has good softness, air permeability and good strength. , It has a wide range of applications in the fields of medical and health care, filtration and separation. Among them, the application of polypropylene-based spunbonded nonwoven materials in the field of medical and sanitary products such as wound dressings, diapers and sanitary napkins has greatly increased with the increase of China's population and the improvement of convenience consumption awareness. However, with the sharp increase of its output, people's requirements for softness and elasticity have increased; how to improve the flexibility and elasticity of p...
