Fine-denier polypropylene spunbond needle-punched non-woven fabric with ultra high tensile stress at specific elongation and manufacturing process thereof

Abstract

The invention discloses a fine-denier polypropylene spunbond needle-punched non-woven fabric with ultra high tensile stress at specific elongation and a manufacturing process thereof. The fine-denierpolypropylene spunbond needle-punched non-woven fabric with the ultra high tensile stress at the specific elongation is prepared from a raw material polypropylene and an auxiliary material anti-ultraviolet master batch; the thickness of a polypropylene filament is 6-8D, and the polypropylene is prepared from, by weight, 90-96 parts of polypropylene slices and 3-6 parts of the anti-ultraviolet master batch; the fine-denier polypropylene spunbond needle-punched non-woven fabric with the ultra high tensile stress at the specific elongation is prepared through the processes of raw material transport, mixing, fusion, extrusion, spinning, cooling, drafting, separator laydown, fiber web needling reinforcement, stentering, shaping and coiling; the product has natural chemical stability, long service life, light texture and high strength, does not have toxic substances, and is environmentally friendly, good in product uniformity and high in mechanics index.

Description

technical field [0001] The invention relates to a polypropylene spun-bonded needle-punched nonwoven fabric, in particular to a super-strength fixed-stretch fine-denier polypropylene spun-bonded needle-punched nonwoven fabric and a manufacturing process thereof. Background technique [0002] At this stage, the needle-punched nonwovens used in industrial supplies, automotive supplies, filter materials, papermaking blankets, geotextiles and other products in China are mainly short-fiber needle-punched nonwovens, but short-fiber needle-punched nonwovens have insufficient strength, High price and other shortcomings, for this reason, spunbond nonwovens produced by acupuncture methods such as polypropylene (PP) spunbonded needlepunched nonwovens (hereinafter referred to as PP spunbonded needlepunched fabrics) are being developed as substitutes. PP spunbonded needle-punched fabric not only has better strength, but also has better filterability, drainage, reverse osmosis, mechanical ...
