Needle-punched non-woven fabric is a kind of non-woven fabric, which is made of polyester and polypropylene raw materials and
is appropriately hot-rolled after repeated acupuncture.
According to the unused technology, with different materials, hundreds of products are made. It is made of polyester and polypropylene raw
materials, which are carded, combed, pre-acupuncture and main acupuncture.
Needle-punched nonwoven structure:
The center is added with a mesh interlayer, and then double-passed, air-laid acupuncture and composite into a cloth. The post-pressure filter cloth has a three-dimensional structure. After heat setting, after singeing,
the surface is treated with a chemical oil agent to make the filter cloth appearance. Smooth, uniform distribution of micropores, the density of the product is good from the surface, the surface of both sides is smooth and
breathable, and the filtration on the plate and frame compressor proves that high-strength pressure can be used, and the filtration precision is up to 4 microns.
The non-woven fabric has no latitude and longitude lines, is very convenient for cutting and sewing, and is light and easy to shape.
It is very popular among handicraft lovers.
Because the needle-punched nonwoven fabric is a fabric formed without spinning woven fabric,
only the woven short fibers or filaments are oriented or randomly stretched to form a web structure, and then mechanical, thermal
bonding or chemical methods are employed. Reinforced.
Instead of interlacing and braiding the yarns one by one, the fibers are bonded directly together by physical means,
so when you get the sticky name in your clothes, you will find that It is impossible to draw a single thread.
Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output, low cost,
wide application and many sources of raw materials.
The relationship between non-woven fabric and spunbond fabric
Spunbond and non-woven fabrics are affiliation. There are many production processes for the manufacture of non-woven fabrics, among which the spunbonding method is one of the
non-woven fabric production processes of spunbonded non-woven fabrics (including spunbonding, meltblowing, hot rolling, hydroenthalation, now Most of the products on the market are non-woven fabrics produced by the spunbond method)
According to the composition of the non-woven fabric, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different ingredients will have different non-woven styles.
The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of the two fabrics are very close, which can be judged by high temperature test.
Non-woven use:
Non-woven products are rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and elegant, with various patterns and styles, light weight, environmental
protection, and recyclability. They are recognized as environmentally friendly products that protect the earth's ecology.
Suitable for agricultural film, shoemaking, leather, mattress, quilt, decoration, chemical, printing, automotive, building materials, furniture and other industries, and clothing lining, medical and health
disposable surgical gowns, masks, caps, sheets, hotels Disposable tablecloths, beauty, sauna and even today's fashionable gift bags, boutique bags, shopping bags, advertising bags and more.
Environmentally friendly products, versatile and economical.
Non-woven environmental protection
The non-woven fabric is made of a chemical fiber and a plant fiber on a wet or dry paper machine under the condition of using water or air as a suspending medium, and is a non-woven fabric although it is a cloth without being woven.
Non-woven fabric is a new generation of environmentally friendly materials, which has the advantages of strong strength, breathable waterproof, environmental protection, flexibility, non-toxic and tasteless, and low price.
It is a new generation of environmentally friendly materials with water repellent, breathable, flexible, non-combustible, non-toxic, non-irritating and rich colors.
If the material is naturally decomposed outside, it has a long life of only 90 days. It is decomposed within 8 years in the room. It is non-toxic, odorless and has no residual substances when burned, so it does not pollute
the environment, so environmental protection comes from this.
Non-woven material characteristics
Non-woven fabric is a kind of non-woven fabric, which directly uses high-polymer slicing, short fiber or filament to pass the fiber through airflow or
mechanical netting, and then through hydroentanglement, needle
punching, or hot-rolling reinforcement, and then finishing. Formed non-woven fabric.
The new fiber product with soft, breathable and flat structure has the advantages of no lint formation, strong, durable, silky softness, also a kind of reinforcing material, and
also a cotton feeling, compared with
cotton, non-woven The cloth bag is easy to form and is cheap to make.
Material characteristics:
1. Light weight: Polypropylene resin is the main raw material for production. The specific gravity is only 0.9, only three-fifths of cotton, which is fluffy and feels good.
2. Soft: Made of fine fiber (2-3D) light-point hot melt bonding. The finished product is soft and comfortable.
3. Water and air permeability: polypropylene chips do not absorb water, the water content is zero, the finished product has good water repellency, and it is composed of 100% fiber with porosity, good gas
permeability, easy to keep the cloth surface dry and easy to wash.
4. Non-toxic, non-irritating: The product is produced in accordance with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, has
no odor, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, which is free of insects and can isolate the bacteria and insects in the liquid. Antibacterial, alkali corrosion, and finished
products do not affect the strength due to erosion.
6. Antibacterial properties. The product has water-extracting properties, is not moldy, and can isolate the bacteria and insects in the liquid, and is not mildewed.
7. Good physical properties. It is made by directly spinning polypropylene into a mesh, and the strength of the product is better than that of the general staple fiber product, the strength is non-directional, and
the longitudinal and transverse strengths are similar.
bonding or chemical methods are employed. Reinforced.
Instead of interlacing and braiding the yarns one by one, the fibers are bonded directly together by physical means, so when you get the sticky name in your clothes,
you will find that It is impossible to draw a single thread.
