Description
Technical field
The present invention relates to a kind of Polywoven Bag technical fields, and in particular to a kind of drawing process of mesh bag.
Background technology
Mesh bag is exactly the plastic braid with big-sized mesh for conversational implication, at present in developed country's farm packet
Some places of China are included, the careless net of packet generally to be utilized to be packaged it in rolls when transporting turf, Rice bars；In addition, potato, vegetables and fruits etc.
Also transportation and sale is carried out after being packed by mesh bag again, so mesh bag is applied in more and more occasions.Mesh bag needs
Enhance intensity could more preferably meet its be packaged or packaging needed for, a method enhancing intensity is material modification, another method
Be exactly drawing process improve, how by drawing process improvement come improve mesh bag intensity be mesh bag manufacturer be badly in need of.
Invention content
In view of currently known technology there are the problem of, the technical problem to be solved by the present invention is to be that providing one kind can improve
The tensile strength of flat filament more preferably meets the mesh bag drawing process that mesh bag makes requirement.
The present invention adopts the following technical scheme that complete：
Mesh bag drawing process, it is characterised in that include the following steps：A, is added to screw extruder after raw material is mixed, raw material exists
It is heated in the barrel of screw extruder and melts and squeezed out in the molten state by the die head of screw extruder, control traction
Than the thickness of the tubular film of extrusion is made to reach sets requirement；Tubular film is carried out water cooling by b, and water temperature is controlled in 45-50
Degree；Tubular film is cut into wide embryo silk by c with blade；D, embryo silk pass through the first baking oven, and it is fixed to carry out primary heating stretching
Become flat filament after type, the raising of tensile elongation is controlled in 20-25%；E, flat filament passes through the second baking oven after cooling, carries out secondary add
Hot-stretch is shaped, and the raising of tensile elongation is controlled in 5-10%；F, flat filament carry out water cooling, and water temperature is controlled in 45-50 degree；G, it is flat
Silk table face carries out static elimination processing；H, flat filament winding are wound into coiled strip.
In 130-150 degree, the embryo silk elapsed time is 2-3 seconds for the temperature control of first baking oven.
In 108-112 degree, the embryo silk elapsed time is 2-3 seconds for the temperature control of second baking oven.
Temperature in the barrel of the screw extruder is controlled at 260 degree.
After adopting the above technical scheme, the key of the present invention is that flat filament have passed through heating draw forming processing twice；
First time drawing and setting strictly controlled heating temperature and by the time, and embryo silk is made to be added with the high temperature of 130-150 degree rapidly
Heat, so as to stretched for the first time it is elongated during inner materials tentatively homogenized processing；Second of drawing and setting is also tight
Lattice controlled heating temperature and by the times, made flat filament by rapidly with the high-temperature heating of 108-112 degree, so as to stretched for the second time
Inner materials are further homogenized processing in elongated process, most improve the tensile strength of flat filament later.
Specific embodiment
The mesh bag drawing process of the present invention, includes the following steps：A is added to screw extruder, raw material after raw material is mixed
It is heated in the barrel of screw extruder and melts and squeezed out in the molten state by the die head of screw extruder, control traction
Than the thickness of the tubular film of extrusion being made to reach sets requirement, the temperature in the barrel of screw extruder is controlled at 260 degree；B,
Tubular film is subjected to water cooling, water temperature is controlled in 45-50 degree；Tubular film is cut into wide embryo silk by c with blade；D,
Embryo silk passes through the first baking oven, becomes flat filament after carrying out primary heating draw forming, and the raising of tensile elongation is controlled in 20-25%,
In 130-150 degree, the embryo silk elapsed time is 2-3 seconds for the temperature control of first baking oven；E, flat filament passes through the second baking oven after cooling, into
The secondary heating draw forming of row, in 5-10%, the temperature of the second baking oven is controlled in 108-112 degree for the raising control of tensile elongation,
The embryo silk elapsed time is 2-3 seconds；F, flat filament carry out water cooling, and water temperature is controlled in 45-50 degree；G, flat filament surface carry out static elimination
Processing；H, flat filament winding are wound into coiled strip.
After tested, the mesh bag flat filament made from above-mentioned drawing process, in 3 thickness, drawing force can be carried by original 30N
Height arrives 33N, and tensile strength improves 10% or so.
