Abstract
The invention provides an antibacterial flame-retardant nonwoven composite, comprising a first nonwoven layer, a base material layer and a second nonwoven layer sequentially from top to bottom; a first antibacterial layer and an anti-radiation layer are disposed sequentially between the first nonwoven layer and the base material layer, and a second antibacterial layer and a flame-retardant antistatic layer are disposed sequentially between the second nonwoven layer and the base material layer; the first antibacterial layer is a porous nano activated carbon silver-supported antibacterial agent coating 15-50 nm in particle size, and the second antibacterial layer is a bio-polypeptide antibacterial agent layer; the first and second nonwoven layers are made from polyadipic acid/butylene terephthalate, polypropylene and polycaprolactam through melt-blowing; the medical nonwoven composite prepared herein is antibacterial, anti-radiation, flame-retardant and antistatic and is mainly used in the field of medical use.
Description
Technical field
The invention belongs to non-woven fabrics field, particularly relate to a kind of medical antibacterial flame-retardant non-woven composite and system thereof
Preparation Method.
Background technology
Non-woven fabrics (non-weaving cloth) is a kind of fabric that need not spin cotton and weave cloth and formed, simply by textile staple or
Long filament is oriented or supports at random row, forms fibre net structure, then uses machinery, the method such as hot sticky or chemical to reinforce and form.Letter
Single says exactly: it is not the yarns interwoven by one one, knits together, but by fiber directly by the side of physics
Method is bonded together, so, when in you take your clothes viscous title time, it finds that, be can not take out the end of a thread one by one.
Non-weaving cloth breaches traditional weaving principle, and has that technological process is short, speed of production fast, yield height, low cost, purposes
Extensively, the feature such as raw material sources are many, have a wide range of applications in daily production and life.But, along with health of people consciousness
How raising and the attention to quality of life, give oneself the excellent performance through wide variety of nonwoven cloth material, become current
One popular problem.Chinese patent CN1970865A discloses and a kind of is added in non-woven fabrics fiber by the fiber of electroplate
Technology, there is the ability killing common bacteria.Chinese patent CN201109221Y discloses a kind of antibacterial composite non-woven fabric material
Expecting, it is composited by trilaminate material, and outer layer is the water accepting layer that water suction non-woven fabrics makes, and intermediate layer is PE, PU film or waterproof
The waterproof layer that air film makes, nexine is the antibiotic layer that antibacterial nonwoven cloth made makes, and is allowed to be provided simultaneously with water suction, waterproof, antibacterial
Function.Chinese patent CN 104695137A discloses a kind of anti-static nonwoven fabric, this non-woven fabrics by polyester, polyamide-based polymerization
Thing, antistatic additive prepares, and non-woven fabrics fiber diameter prepared by this invention is relatively thin, obtain non-woven fabrics have specific surface area big,
The advantages such as porosity is high, filter efficiency is excellent, flexibility good, comfort is strong, can be widely applied to medical with industrial face mask, warming
The fields such as material, filtering material, medical and health, oil absorption material, cleaning wiping cloth, battery separator and deadener.China is specially
Profit CN204076983U discloses a kind of non-woven fabric composite material for making medical mask, including skin-friendly layer, water accepting layer, the
One PE layer, degerming layer, the 2nd PE layer and hydrophilic PP nonwoven layer, described skin-friendly layer is bonded with one layer of water accepting layer, described water suction
