Nonwoven fabrics, known as nonwovens, are used in a wide range of applications. Needled nonwoven fabrics are divided into dry, wet, and spunlace methods. The needle-punched nonwoven we are talking about today is one of the nonwoven dry nonwoven fabrics. It is made of polyester, polyester, and polypropylene. And these are then treated with appropriate heat pressure after several needling processes. Needled nonwovens are used in various industries. Because it can be made into thousands of products according to different processes and different raw materials.
Needled nonwoven fabric is made of short fibers through a series of processes. And then the fiber network is reinforced into cloth by felting needles to finally form a needle-punched nonwoven fabric. As a nonwoven fabric, it has no warp-weft distinction, the fabric-forming fibers are disorganized. And the difference in performance between warp and weft is not great. Typical products of needled nonwoven fabrics are synthetic leather-based fabrics, needled geotextiles, etc.
Currently, there are several forms of needled nonwoven processes. Pre-puncture, main puncture, patterned needling, circular needling, and tubular needling.
Needled nonwoven fabric products are colorful, bright, fashionable, environmentally friendly, versatile, beautiful, etc... The patterns and styles can be diversified, and the quality is light, recyclable, and non-polluting to the environment. It is suitable for agricultural film, shoe making, leather making, mattress, mother and child quilt, decoration, chemical industry, printing, automobile, building materials, home furniture, and clothing interlining, medical and health disposable surgical gown, mask, cap, bed sheet, hotel disposable tablecloth, beauty, sauna, gift bag, boutique bag, shopping bag, advertising bag, etc... Categorized as follows.

Needled nonwoven fabric is a new generation of eco-friendly materials with the following specific characteristics.
1. Suitable for various fibers, mechanical entanglement does not affect the original characteristics of the fiber.
2. Flexible entanglement between fibers, with good dimensional stability and elasticity.
3. Good permeability and filtration performance.
4. Full and fluffy handfeel.
5. Eco-friendly and pollution-free, the edge material can be recycled.
6. Can be manufactured according to the requirements of various geometric patterns or three-dimensional molding products.
7. Good strength, water repellent, non-combustible, colorful.
8. Non-toxic, tasteless, environmental protection when burning.
The approximate process flow of the needled nonwoven fabric is. Weighing and feeding - Opening machine - Cotton feeding machine - Carding machine - Spreading machine - Needling machine - Ironing machine - Winding machine - Finished product. The following is the process diagram of needled nonwoven fabric.
Step 1.
Weighing feeding. According to the actual need to calculate the different fiber proportions. According to the proportion of weighing feeding
Step 2.
Opening, blending, carding, spinning out, spreading network. These processes are completely dependent on machinery and equipment to complete. The stability of product quality depends on the stability of the equipment, and the staff's work ethic.
Step 3.
Needling: the use of needling equipment for operation, the staff by the product style and requirements, adjusting the needling conditions, and determining the number of needling machines used. The staff must also confirm the wear and tear of the needles and determine whether to change them according to the actual situation and if necessary, use special needle plates.
Step 4.
Check and roll: Before rolling, the machine detects whether there is any needle leakage on the non-woven fabric by means of metal detection.
The sources of needle-punched nonwoven fabrics are mainly concentrated in several places in China. Changshu in Jiangsu, Nangong in Hebei, and Dongguan in Guangdong. Changshu mostly focuses on colored nonwoven fabrics, Nangong mainly does high-density felt, and Dongguan in Guangdong mainly focuses on customized needled nonwoven fabrics, which are of higher quality than the other two places and are suitable for customers with high requirements for quality.
