Super-soft spunbond nonwoven cloth double reinforcing and forming technology

Abstract

The invention provides super-soft spunbond nonwoven cloth double reinforcing and forming technology. The technology includes following steps: fully mixing and feeding 81-86.5 parts of polypropylene PP, 12.5-16 parts of allyl elastomer, 0.5-1.5 parts of soft masterbatch and 0.5-1.5 parts of titanium dioxide into a hopper; fusing, filtering, and entering a spinning system; cooling filament obtainedby spinning through lateral cooling air to obtain primary filament; performing airflow drafting on the primary filament to obtain a fiber net; feeding the fiber net into a hot mill through continuousconveying of a finished net conveying belt for reinforcing, and performing spunlace reinforcing after hot milling to obtain nonwoven cloth; spraying antibacterial finishing liquid to the nonwoven cloth through an antibacterial treatment system, and conveying the nonwoven cloth into an oven for drying. A spunbond-spunlace double reinforcing process is adopted to produce the nonwoven cloth to replace conventional hot air cloth production, so that the nonwoven cloth has the characteristics of being fluffy, soft and skin-friendly. A novel nonwoven cloth processing technique is adopted, so that a direction is provided for development of the nonwoven cloth in the future.

Description

【Technical field】 [0001] The invention relates to the technical field of non-woven fabric production, in particular to a double-reinforced forming technology for ultra-soft spun-bonded non-woven fabrics. 【Background technique】 [0002] Non-woven fabrics are non-woven fabrics. It is a non-woven fabric formed by directly using high polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then strengthened by water entanglement, needle punching or hot rolling, and finally finished. Woven cloth. Spunbonded non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber The net becomes a non-woven fabric; spunlace non-woven fabric: it sprays high-pressure fine water onto one or more layers of fiber nets to entangle the fibers with each other, so that the fiber nets ca...

Spunbonded non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber The net becomes a non-woven fabric; spunlace non-woven fabric: it sprays high-pressure fine water onto one or more layers of fiber nets to entangle the fibers with each other, so that the fiber nets can be reinforced and have a certain strength. The hand feel of spunlace is not soft enough, while the spunlace non-woven fabric is comfortable and soft, but its strength is insufficient. Now a super-soft spunbond non-woven double reinforcement forming technology is proposed.
