The meltblown process is a nonwoven manufacturing process converting polymers into continuous filaments into a random laid nonwoven fabric. The process involves high velocity air blowing molten resin from an extruder tip onto a conveyor to form a fine fibrous and self-bonding web.
The fibres in the meltblown web are laid together by a combination of entanglement and cohesive sticking. The ability to form a web directly without stretching gives meltblown technology a distinct advantage over other systems.
In the meltblown system, molten polymers are forced through small slit openings and high temperature air is impinged (300-500 miles/hr) at both sides of the exiting film. The fast-moving air streams effectively stretch or attenuate the molten polymer and solidify it into a random array of discontinuous fibers. The fibers are then condensed as a randomly entangled web and compressed between heated rolls.
The meltblown process is unique amongst nonwoven processes. It can be compared to a high tech method of making cotton candy. In making cotton candy, the sugar is melted and pressure is fed through small openings in a spinning wheel, the sugar then thickens and is stretched into fibres by centrifugal forces.
Spunbond nonwoven fabrics are formed after the polymers have been extruded and stretched to form continuous filaments. The filaments are laid into a net and is then bonded to make the web of nonwoven fabric. This is one of the most popular methods of producing polymer-laid nonwovens and is based on the melt spinning technique.
Polymers are melted and extruded, then spun into fine fibers which are laid and bonded by heated rollers to form spunbond fabrics. By bonding together extruded spun filaments to create a consistent web of material, spunbond can be produced using endless filaments of fiber or flakes.
Due to its versatility the product can be used in a variety of industries including: medical and hygiene, agriculture, construction, packaging and the automotive industry. Our spunbond nonwoven fabric is a high-performance material, with good resistance to heat, as well as high tensile strength and stability.
Elastic laminate is comprised of breathable elastomeric film and a nonwoven web traditionally used to provide barrier properties in disposable products. Laminates of films have been used to create materials which are both impervious and somewhat cloth-like in appearance and texture.
Examples of usage includes, health and surgical products such as drapes, gowns, and disposable work wear. It also is used in personal care absorbency products such as diapers, training pants, sanitary napkins, bandages, wipes and incontinence products.
Needle punched nonwoven fabrics are made from various fibrous webs in which fibres are bonded together mechanically through entanglement and friction after fine needle barbs repeatedly penetrate through the fibrous web.
In needle punching, barbed needles are punched vertically through the web to hook and entangle tufts of fibres resulting in a nonwoven fabric resembling felt in appearance.
Needle punched fabrics frequently are found in carpeting and other floor coverings, wall coverings, blankets, padding material, insulation materials, and industrial fabrics for vehicles and other industries.
The use of wire forming machines allows us to achieve a wide variety of customer specifications of wire shaping.
When shaped for the usage in PPE such as masks, having a durable nose bridge wire can allow for a comfortable secure fit and minimizes the need to adjust the mask.
Wire forming can be adopted in all industries, and we can customize and design solutions for your wire forming needs.
