Solution Blow Spinning Nonwoven for Medical and Filtration Applications in India
Solution blow spinning nonwoven medical filtration India raw materials are supplied by Favourite Fab to air filter manufacturers, medical barrier fabric converters, and wound care producers. Solution blow spinning produces microfibre and nanofibre webs using high-speed pressurised air — without the high-voltage electrical field required by electrospinning. B2B manufacturers source solution-blown nonwoven rolls from Favourite Fab for scalable microfibre production at competitive wholesale pricing with India-based supply reliability.
What Is Solution Blow Spinning Nonwoven
Solution blow spinning (SBS) is a fibre-forming process that combines elements of electrospinning and meltblowing. A polymer solution is fed through a concentric die — an inner nozzle surrounded by an outer high-speed air annulus. The pressurised air accelerates and stretches the polymer solution jet into fine fibres. The solvent evaporates during fibre flight, and the dried fibres are deposited on a collector screen to form a nonwoven web.
Unlike electrospinning, SBS requires no high-voltage power supply, making it safer to scale for industrial production. Unlike meltblowing, SBS processes polymers in solution rather than as a melt — enabling use of biopolymers and temperature-sensitive polymers that cannot be melt-processed.
Fibre diameters achievable by SBS range from 200 nm to 5 µm, depending on polymer concentration, air pressure, and nozzle geometry. This places SBS between electrospinning (finer fibres) and meltblowing (coarser fibres) in the fibre diameter spectrum — at a process complexity and cost level accessible for industrial-scale production.

Applications in Hygiene and Medical Manufacturing
Solution blow spinning nonwoven medical filtration India applications are expanding as manufacturers seek biopolymer-based and scalable microfibre solutions. Air filter producers use SBS microfibre layers as a middle filtration stage in multi-layer HVAC and cabin air filter assemblies. The microfibre layer captures 1–5 µm particles that pass through the upstream coarser pre-filter layer.
Medical mask manufacturers use SBS filter media as the filtration layer in surgical masks and procedure masks. SBS media made from PLA offers a biodegradable alternative to PP meltblown — addressing sustainability requirements in healthcare procurement.
Wound care dressing converters use biocompatible PLA and PLGA SBS webs as the wound-contact layer in advanced dressings. These biopolymer fibres support cell attachment and can be formulated to degrade in contact with wound exudate, reducing dressing change frequency.
Drug delivery researchers and pharmaceutical manufacturers use SBS to incorporate active pharmaceutical ingredients directly into fibre webs for transdermal and wound-applied drug delivery systems.

Frequently Asked Questions
What is the difference between solution blow spinning and meltblowing?
Meltblowing processes molten polymer at high temperature, limiting it to thermoplastics like PP and PET. Solution blow spinning dissolves the polymer in solvent before processing, enabling biopolymers like PLA, PLGA, and cellulose acetate — and producing finer fibres at lower processing temperatures. SBS is preferred when polymer thermal stability or biodegradability is required.
Can Favourite Fab supply biodegradable solution blow spinning nonwoven?
Yes. We supply SBS nonwoven made from PLA (polylactic acid) and PLGA. These biopolymer webs are compostable under industrial composting conditions. PLA and PLGA grades are also available in biocompatible versions for medical and wound care applications.
What filtration efficiency does solution blow spinning nonwoven achieve?
SBS microfibre webs achieve 85–98% filtration efficiency at 1 µm depending on fibre diameter and basis weight. For higher efficiency at submicron particle sizes, we recommend combining SBS with our electrospun nanofibre layer. Multi-layer configurations are available.
Is solution blow spinning nonwoven suitable for medical device packaging?
SBS nonwoven can be used as a breathable barrier layer in medical device packaging when made from compatible polymers and tested to ISO 11607. Contact our technical team for packaging-grade material specifications and validation support.
How does solution blow spinning compare to electrospinning?
Electrospinning produces finer fibres (50–500 nm) but requires a high-voltage field and is more challenging to scale industrially. Solution blow spinning produces slightly coarser fibres (200 nm–5 µm) using air pressure only, making it safer and more scalable at lower capital cost. For sub-200 nm applications, electrospinning remains the preferred process.
Does Favourite Fab export solution blow spinning nonwoven?
Yes. We export SBS nonwoven rolls to filter manufacturers, medical device companies, and dressing converters in Southeast Asia, the Middle East, Africa, and Europe. Full export documentation and technical data sheets are provided with each shipment.
