Spunbond Machine

Spunbond Machine, the main material is polyester and polypropylene, with high strength and high temperature resistance

definition


Spunbond Machine: After extruding and stretching the polymer to form continuous filaments, the filaments are laid into a web, and the web is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement methods to make the fiber web. into a non-woven fabric.

Features


Good high temperature resistance, good low temperature resistance (polypropylene can be used for a long time at 150°C, polyester can be used for a long time at 260°C), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance , sound insulation, moth-proof, non-toxic.

The main purpose


The main materials of Spunbond Machines are polyester and polypropylene.
The main products of Spunbond Machines are polypropylene and polyester (long fiber, staple fiber) non-woven fabrics. The most common and commonly used applications are non-woven bags, non-woven packaging, etc.; for Spunbond Machines It is easier to identify, generally has good two-way fastness, and the rolling point of general Spunbond Machines is diamond-shaped.
At the application level, it can also be used as flower packaging cloth, luggage cloth, etc. The characteristics of wear resistance, firm hand feeling, etc. make it the best choice for making such products.

Process flow


Polypropylene: polymer (polypropylene + return material) – large screw high temperature melt extrusion – filter – metering pump (quantitative conveying) – spinning (spinning inlet and outlet stretching and suction) – cooling – Air Traction – Net curtain forming – Upper and lower pressing rollers (pre-reinforcement) – Mill hot rolling (reinforcement) – Winding – Reverse distribution and slitting – Weighing and packaging – Finished product storage
Polyester: processed polyester chips – large screw high temperature melt extrusion – filter – metering pump (quantitative conveying) – spinning (spinning inlet up and down stretching and suction) – cooling – air traction —— Net curtain forming —— Upper and lower pressing rollers (pre-reinforcement) —— Hot rolling of rolling mills (reinforcement) —— Winding —— Reverse distribution and slitting —— Weighing and packaging —— Finished product storage

Type of technology


The world’s spunbond non-woven technology mainly includes Lacoffel technology from Reifen, Germany, STP technology from Italy, and Kobe Steel technology from Japan. The current situation, especially with Reffin technology becoming the mainstream technology in the world. Has developed to the fourth generation of technology. It is characterized by the use of negative pressure ultra-high-speed air drafting, and the fiber can be stretched to about 1 denier. Many domestic enterprises have already made imitations. Since there are many cutting-edge problems in its core technology that have not been solved or mastered, it will take time for domestic equipment manufacturers to reach the technical level of Refine.

Meltblown cloth production line application range

Melt blown Machine (Melt blown Machine) is a product made of high melt index PP (polypropylene) as raw material and composite non-woven fabric. It is the core material of the mask. The diameter of the spinning fiber can reach 0.001-0.005 mm. It has many voids, fluffy structure, good wrinkle resistance, and has a unique capillary structure. The ultra-fine fibers increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. . Its main uses include air filtration, acid breaking liquid filtration, food hygiene filtration, industrial dust mask production, etc. In addition, it can also be used as medical and sanitary products, industrial precision wipes, thermal insulation materials, oil absorbing materials, battery separators, imitation leather base cloth and many more

Air purification field


Used for air purification filter element and air filtration, it has the advantages of low resistance, high strength, long service life and low price.

Medical field


Medical masks, dust masks, protective clothing, and SMS products compounded with spunbond fabrics to make surgical gowns and other medical supplies

Medical masks generally adopt a multi-layer structure, referred to as SMS structure: a single-layer spunbond layer (S) on both sides, a single-layer or multi-layer meltblown layer (M) in the middle, and the meltblown layer brings virus filtering to the mask. The main material is the Melt blown Machine in the middle, referred to as melt-blown cloth. Meltblown cloth is the core material of the mask. The meltblown cloth mainly uses polypropylene as the main raw material. It is melted and filtered by a screw extruder and extruded from the spinneret hole of the nozzle, and is subjected to high-speed hot air at the exit of the spinneret hole. The flow is sprayed to obtain ultra-fine short fibers that are stretched and formed, and the fiber diameter can reach 1 to 5 microns. It has many voids, fluffy structure and good wrinkle resistance. The ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths and other fields.

Filter material


With excellent filtration performance and good diaphragm material, it has been widely used in the field of filtering acid and alkaline liquids and oils

Industrial wipes


Relying on the adsorption of fine fibers as an oil-absorbing material, it is used in environmental protection projects, oil-water separation projects, and cleaning of oil and dust.

Thermal material


Meltblown fibers have large surface area and high porosity to prevent heat loss and are widely used in clothing and thermal insulation materials.

Health field


Suitable for diapers, incontinence pads, women’s sanitary napkins, wipes, shoe covers and other cleaning needs material applications

Decorative cloth


Household items: spring cloth, bedding, seat supplies, etc.

Industrial cloth


The field of mud bag automobile, bagging, geotextile wrapping cloth, agricultural protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.

Packaging Supplies


Shopping bags, rice bags, tea bags, clothing packaging, etc.
