Non-woven fabrics are much more popular than meltblown fabrics in daily life, such as nonwoven handbags, wrapping paper, and outer layer of masks, etc. Can you distinguish clearly between these two kinds of fabrics? If not, don’t worry, and Hail Roll Fone will explain the major four differences between them.
Meltblown fabric, also known as melt-blown non-woven fabric, is simply a sub-category of nonwoven fabric process. However, there are many differences between melt-blown and non-woven fabrics, mainly in terms of material, characteristics, process and application.
1. Different materials
Melt-blown fabric is mainly made of polypropylene and its fiber diameter can reach 1~5 microns.
Non-woven fabric, also known as needle-punched cotton or needle-punched non-woven fabric, is generally made of polyester fiber and polyester fiber material and produced by using pp spunbond non woven fabric machine.
2. Different characteristics
With more voids, fluffy structure and good wrinkle resistance, melt-blown fabric has a unique capillary structure of ultra-fine fibers to increase the number and surface area of fibers per unit area, thus enabling melt-blown fabrics to have good filtering, shielding, and oil absorption properties, which makes it become the core material of masks.
Non-woven fabric has the features of moisture-proof, breathable, flexible, lightweight, flame retardant, non-toxic and tasteless, inexpensive, and recyclable, etc.
3. Different applications
Melt-blown fabric can be used in the fields of air and liquid filtration materials, isolation materials, absorbent materials, mask materials, oil-absorbent materials and wiping cloths.
Non-woven fabrics, compared to meltblown fabric, are more widely and commonly used. Non-woven products are colorful, light, environmentally friendly and recyclable with various patterns and styles, and are suitable for agricultural film, shoes, leather, mattress, decoration, chemical, printing, automobile, building materials, furniture and other industries.
In short, melt-blown fabrics are suitable for specialized fields with higher standards, while non-woven fabrics are more versatile in general.
4. Different manufacturing processes
With regard to melt-blown fabrics, polymer slices with high melt index are extruded and heated to melt into a high-temperature melt with good flowability. The melt stream ejected from the spinneret is blown into very fine fibers by high-temperature and high-speed hot airflow, which are gathered into a fiber network on a receiving device (such as a netting machine) and bonded to each other to form a fabric using its own residual heat.
There are many manufacturing processes for non-woven fabrics, including spunbond, meltblown, hot-rolled and spunlace. Most of the non-woven fabrics on the market now are produced by pp spunbond non woven fabric machine. It generally uses polymer slices, staple fibers or filaments directly to form a web of fibers through airflow or machinery, then hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishing to form a non-woven fabric.
