Problems solved by technology
[0003] At present, the woven fabrics manufactured, sold and used at home and abroad, such as grass-proof cloth, thermal insulation quilt cover, sun net, ton bag, plastic woven bag, etc., are made of polypropylene PP or polyethylene PE, and their defects are PP or PE has poor UV resistance and high temperature resistance, short service life, and serious environmental pollution. PET polyester material has strong UV resistance and high temperature resistance, and its woven fabric has a long service life, but its raw material PET polyester exists The glass transition temperature is high, the melt viscosity is small, the molecular chain is rigid, and the molecular rearrangement is slow. The process of manufacturing PET polyester flat yarn is extremely sensitive to moisture and temperature, so domestic and foreign professional and technical personnel are still unable to make PET PET polyester flat yarn drawn from polyester

The invention discloses a PET (polyethylene terephthalate) polyester flat filament drawing machine technique. According to the technique, PET (polyethylene terephthalate) flat filaments are produced using PET polyester raw material melt or waste polyester regenerated melt so as to produce woven cloth. The technique is characterized in that polyester cast film formed by a melt coming out through aflat film die head is pasted on a cooling roller under the action of an electrostatic pasting device, is cooled down and quickly enters water in a cooling water tank to be further cooled and crystallized to shape; the cooling roller is in contact with the water in the cooling water tank for cooling; film drawing, slitting, strip drawing, heating stretching, secondary heating stretching and heat setting are carried out before winding, and flat filament cones obtained after winding are supplied to a subsequent procedure for producing woven cloth. The PET (polyethylene terephthalate) polyester flat filament drawing machine has the advantages that The woven cloth produced from PET polyester material, such as weed barrier cloth, thermal insulation cloth, sunshade net and packaging bags, has good anti-aging performance, high temperature resistance and high strength.
