Special antibacterial agent for spunbond non-woven fabric
I. Overview of the Requirements for Antibacterial Modification of Spunbond Nonwoven Fabrics
PP spunbond non-woven fabric is widely used in fields such as medical protection, hygiene care, and household filtration. The common base material is prone to the growth of Escherichia coli, Staphylococcus aureus, and mold, presenting problems such as cross-infection, unpleasant odors, and moldy conditions.
Adding special antibacterial additives can endow the non-woven fabric with long-lasting antibacterial properties from the raw material stage, without compromising the basic physical properties such as breathability, softness, and stretchability of the fabric. This also enhances the product's added value and hygiene safety level.
II. Core Technology Principles of Dalian Tianwei Chemical Co.,Ltd Nonwoven Fabrics Antibacterial Agent
Employing a silver-zinc composite inorganic slow-release antibacterial system, combined with the nano-zirconium phosphate carrier loading process:
Silver ions quickly penetrate the bacterial cell membrane and kill pathogenic bacteria within a short period of time.
Zinc ions can effectively inhibit the metabolic and reproductive activities of the bacterial population, preventing repeated proliferation.
The antibacterial components are embedded within the fibers, which are resistant to friction and do not easily disperse or leak out. Moreover, they are not prone to causing microbial resistance.
Adapt to two mainstream processes for spunbond fabric production:
Melt blending: During the production process, PP raw materials are mixed in, and a single-piece molding is achieved, with durable antibacterial properties.
Post-treatment of immersion coating / spraying: The surface of the finished non-woven fabric is well adhered. The operation is simple.
Broad-spectrum and highly effective antibacterial
The antibacterial rate against common bacteria, fungi and molds is ≥ 99.9%, meeting the medical and maternal-infant hygiene testing standards.
High-temperature-resistant compatible spunbond process
Excellent thermal stability, capable of withstanding the high-temperature extrusion molding process of spunbonding. The processing is free from volatilization, yellowing or color spots, and does not affect the fabric's feel and transparency.
Environmental protection, safety and skin-friendly
Free of formaldehyde, chlorine and irritating heavy metals, it complies with RoHS and REACH environmental standards. It is non-toxic and non-irritating, and can be directly in contact with the skin and the base materials of baby products.
Compatible and stable, with low addition amount
It is compatible with PP raw materials and various non-woven fabric additives. A small amount of addition can achieve long-term antibacterial effects without increasing the production cost burden.
Long-lasting weather-resistant and mold-resistant
In high-humidity and long-term usage environments, the antibacterial effect decays less significantly. It can effectively inhibit mold growth and unpleasant odors on the fabric, and extend the service life of the non-woven fabric.
IV. Application Scenarios of Adhesive Nonwoven Fabrics
Medical protection: Disposable protective suits, surgical drapes, medical masks, isolation sheets, disinfection cloths
Hygiene for Mothers and Infants: Surface of disposable diapers, inner fabric of sanitary napkins, urine barrier pads, baby care non-woven fabric
Household daily use: Pet beddings, dust removal and cleaning cloths, non-woven fabrics for home textiles interiors
Industrial filtration: New air and air conditioning spunbond filter substrates, to prevent bacterial colonies and mold growth on the filter materials
