- What is nonwoven fabric?
-
Non-woven fabric, also known as non-woven cloth, is a type of fabric that is not woven in the traditional way.
Instead, it is made by shaping natural or synthetic fibers into a cloth-like structure through physical and chemical techniques. Depending on the raw materials and manufacturing processes, non-woven fabrics will have different properties.Non-woven fabrics eliminate the cumbersome process of traditional weaving. They can be directly manufactured by simply inputting raw materials. They have advantages such as diverse raw materials, short processing time, fast speed, low cost, and wide range of applications.
In daily life, they are used in clothing, masks, face masks, cotton pads, wet wipes, and bags. In industry, they are used in automotive materials, shoe materials, filter materials, and even gardening and geotechnical applications.
- Raw materials for non-woven fabrics
-
The raw materials for nonwoven fabrics can be divided into natural fibers and man-made fibers. Natural fibers include cotton, wool, silk, and hemp, while man-made fibers include polyester fiber (PET), polyethylene fiber (PE), polypropylene fiber (PP), rayon, and so on.
Different fibers have different properties. Natural fibers are generally more difficult to obtain and therefore more expensive, while man-made fibers have a wider range of applications and lower costs. Ultimately, the choice of raw materials should be based on their properties and functionality.

Needle-Knitted Nonwoven Fabric
Also known as needle-punched nonwoven fabric, it uses a dense array of needles to pierce and hook the fibers at high speed on the fabric surface, causing the fibers to become entangled and bonded together.
Nonwoven fabrics manufactured using the needle-punching method are characterized by their durability and high strength, and are widely used in flooring, filtration, carpets, leather base fabrics, shoe reinforcement materials, shoe midsoles, automotive materials, agricultural planting bags, etc., and are the main products of our company HSINNJY !
Stitch-Bonded Nonwoven Fabric
Also known as sewn nonwoven fabric, it is reinforced by sewing yarns together after the fibers are carded and laid into a web. It has the characteristics of high strength and high durability and is often used as a bonding base fabric and reinforcing material.
This is also one of the main products sold by our company!Water-Jet Nonwoven Fabric
By spraying extremely fine, high-pressure water jets onto the combed fiber web, the force of the water causes the fibers to wrap and reinforce, resulting in a clean and delicate fabric that is not prone to lint.
This makes it ideal for applications that come into contact with human skin, such as face masks and wet wipes.Hot Air Nonwoven Fabric
Some fibers are melted by hot air or other heating methods, causing the fiber web to bond together into a fabric. Due to its fluffy properties, it can be used as a medical and hygiene material such as sanitary napkins and diapers.
It is also often used in filter cloths, sound-absorbing and heat-insulating materials, etc.Spunbond Nonwoven Fabric
The molten raw material is ejected from the nozzle and stretched into continuous filaments, which are then stacked to form a mesh, and then reinforced to become a fabric.
It can be found in carpet base fabrics, roofing waterproofing materials, filter materials, and car interior linings.Meltblown Nonwoven Fabric
The molten raw material is sprayed out of the nozzle while hot air is blown out, forming extremely fine fibers that are blown onto the roller and bonded together to form a mesh structure.
Because the fibers are extremely fine and have a high density, they are suitable as a filter layer for masks and other filter materials.
