  Spunbonded nonwoven fabric Spunbonded non-woven fabric, mainly made of polyester and polypropylene, has high strength and good high temperature resistance Definition editing spunbonded non-woven fabric: after extruding and stretching the polymer to form continuous filaments, the filaments are laid into a web, and then the web is transformed into non-woven fabric through self bonding, thermal bonding, chemical bonding or mechanical reinforcement
Good high temperature resistance, low temperature resistance (polypropylene fiber can be used for a long time at 150 ℃ and polyester fiber can be used for a long time at 260 ℃), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth proof and non-toxic
The main materials of spunbonded non-woven fabrics are polyester and polypropylene
The main products of spunbonded non-woven fabrics are polypropylene and polyester (long fiber and short fiber)
The most common and commonly used applications are non-woven bag, non-woven packaging, etc; It is easy to identify spunbonded non-woven fabrics
Generally, the two-way fastness is good
Generally, the rolling point of spunbonded non-woven fabrics is rhombic
The application level can also make flower packaging cloth, luggage cloth, etc
the characteristics of wear resistance, firmness and good hand feel make him the best choice for making such products Hot rolled non-woven fabric , Hot rolled non-woven fabric editing discussion upload video this entry lacks an overview map

Hurry to edit it! Hot rolling is the last net forming technology in the production process of non-woven fabrics
It is a process of cooling and silk laying to achieve fabrics, Hot rolling has high heat (100 ~ 150 ℃ & middot; the rolling wheel rolls the uniform fiber to melt and form a network, so there will be rolling spots on the cloth surface of hot-rolled non-woven fabric, which is similar to pinholes, but does not penetrate
The specific size depends on the size and density of the steel thorn on the rolling wheel
[br /] To sum up, as a process, hot-rolled non-woven fabric is not a specific kind of fabric, but the general name of a kind of non-woven fabric formed by similar processes
Generally speaking, The hot rolling treatment process is spunbonded polypropylene non-woven fabric (PP), polyester non-woven fabric (PET), PA nylon (PA)
The biggest difference between these three types is the difference of processing raw materials
main raw material editor (1
Natural fiber: cotton, wool, hemp and silk; (2
Conventional fiber: viscose fiber, polyester fiber, acetate fiber, polypropylene fiber and polyamide fiber; (3) differentiated fiber: superfine fiber, profiled fiber, low melting point fiber, high crimp fiber and antistatic fiber; (4) high functional fibers: aromatic polyamide fibers, carbon fibers, metal fibers
feature editing non-woven fabrics can have many characteristics and distinguishing properties, such as non entangled edges and unique fiber orientation in the fabric
They can be soft or hard, strong or weak, oriented and omnidirectional in performance, with one or both sides smooth or uneven, providing bulk or very compact, two or three dimensions, Solid or patterned openings, absorbent or repellent and porous puncture
Many of these functions can be combined in one receipt to meet an end-use product
Nonwovens can stretch, stretch, recover and have a specific aperture, but cannot be drawn
This is a very important difference between nonwovens and textile fabrics
In addition, they can provide excellent substrates for coatings, composites, lamination, printing, embossing and forming, so they are often used in packaging materials
Relatively speaking, nonwovens as packaging materials are more expensive than ordinary packaging cartons, This is also the reason why it has not been widely used
If non-woven fabric manufacturers want to fully open this big market, reducing costs and taking the green route is undoubtedly the biggest challenge Advantages 1
Light weight: polypropylene resin is the main production raw material, with a proportion of only 0
9, only three fifths of that of cotton
It is fluffy and feels good
2
Softness: it is composed of fine fibers (2-3D) and formed by light spot hot melt bonding
The finished product has moderate softness and comfort
3
Water drainage and air permeability: polypropylene chips do not absorb water, have zero moisture content, and the finished products have good water drainage
They are composed of 100% fibers, have porosity and good air permeability, and are easy to keep the cloth dry and easy to wash
4
Non toxic and non irritating: the product is made of food grade raw materials conforming to FDA, does not contain other chemical components, has stable performance, is non-toxic, has no peculiar smell and does not stimulate the skin
5
Antibacterial and chemical resistant agents: polypropylene is a chemical blunt substance, which is not eaten by insects, and can isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, finished products will not affect the strength due to erosion
6
Antibacterial property
The product has water pulling property and is not moldy
It can isolate the erosion of bacteria and insects in the liquid and is not moldy
7
Good physical properties
It is made of polypropylene spinning, directly laid into a net and thermally bonded
The strength of the product is better than that of ordinary staple fiber products
The strength has no directionality and the longitudinal and transverse strength is similar
8
In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene
Although the names of the two substances are similar, they are very different in chemical structure
The chemical molecular structure of polyethylene is quite stable and difficult to degrade, so it takes 300 years for plastic bags to decompose; The chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, so it can be effectively degraded, and enter the next environmental cycle in a non-toxic form
A non-woven shopping bag can be completely decomposed in 90 days
Moreover, non-woven shopping bags can be reused for more than 10 times, and the pollution degree to the environment after abandonment is only 10% of that of plastic bags
Disadvantages 1 Poor strength and durability compared with textile cloth 2 Can not be cleaned like other cloth 3 The fibers are arranged in a certain direction, so they are easy to crack at right angles, etc
Therefore, the improvement of production methods mainly focuses on the improvement of preventing division
Uses (1) medical and sanitary non-woven fabrics: surgical clothes, protective clothing, disinfection bags, masks, diapers, civilian rags, wiping cloth, wet face towel, magic towel, soft towel roll, beauty products, sanitary napkins, sanitary pads, disposable sanitary cloth, etc
(2) Non woven fabrics for home decoration: wall cloth, tablecloth, bedspread, bedspread, etc

The fibers used in the production of classified non-woven fabrics are mainly polypropylene (pp
) and polyester (PET)
In addition, there are nylon (Pa
), viscose fiber, acrylic fiber, polyethylene (HDPE) and chlorine fiber (PVC)
According to the application requirements, non-woven fabrics are divided into two categories: disposable and durable
The difference between non-woven fabrics and dust-free fabrics
Non woven fabrics, also known as non-woven fabrics, are a new generation of environmental protection materials with the characteristics of water repellent, breathable, flexible, non combustion supporting, non-toxic, non irritating and rich colors
If non-woven fabrics are placed outdoors and decomposed naturally, their maximum life is only 90 days, and they are placed indoors for 5 days Decomposition within one year, non-toxic, tasteless and free of any residual substances during combustion, so it does not pollute the environment and is suitable for washing
It directly uses polymer chips, short fibers or filaments to form new fiber products with soft, breathable and planar structure through various fiber mesh forming methods and consolidation technology
It has the environmental protection performance that plastic products do not have, and its natural degradation time is far lower than that of plastic bags
Therefore, the non-woven bag made of non-woven fabric is also recognized as the most economical and environmentally friendly shopping bag
