Abstract
The invention discloses a reinforced non-layered terylene spun-bonded hot rolling non-woven fabric, which is prepared by taking 0 to 5 percent of polyester reinforced masterbatch and a remaining amount of filament-grade polyester slice mixture as raw materials through high-temperature fusion, spinning, tubular air drafting, yarn swaying and net laying, and hot rolling coiling, wherein the temperature of each region of a screw extruder, the spinning temperature, the drafting air pressure as well as the temperature, the pressure and cross parameters of upper and lower rolls of a rolling mill are controlled during the processing. The invention adds the reinforced masterbatch into the raw materials, ensures that the produced terylene filament spun-bonded hot rolling non-woven fabric has no layering phenomenon, greatly improves the strength, is obviously different from a conventional product, and meets the use requirement of customers.
Description
Technical field
The present invention relates to a kind of terylene non-woven fabric, especially high grammes per square metre polyester filament spun-bonded hot rolling non-woven fabric.
Background technology
The polyester filament spun-bonded hot rolling non-woven fabric is to be raw material with long filament level polyester (be called for short PET) section, through crystallizing and drying, high-temperature fusion, spinning, the drawing-off of air-flow tubular type, pendulum wire lapping, hot rolling, batch that continuous one-step produces.At present, polyester filament spun-bonded hot rolling non-woven fabric product especially substance be 100g/m
2Above product, owing to limit by processing mode, the nonwoven fabric of producing all has lamination in various degree, and powerful low, such as producing 250g/m
2Product, layering is serious, and the longitudinal fracture brute force has only about 400N/5cm, and customer requirement reaches more than the 550N/5cm.140g/m
2Product, layering are also very serious, and its longitudinal fracture brute force is generally about 300N/5cm, and customer requirement must reach more than the 350N/5cm.This down phenomenon limits the use of terylene non-woven fabric product in some special industries.For example: in building trade, the terylene non-woven fabric product that house wrap is related requires the nonwoven fabric can not layering.In order to satisfy this demand of client, must a kind of not stratified enhancement mode polyester filament spun-bonded hot rolling non-woven fabric product of invention.
Summary of the invention
For addressing the above problem, the present invention improves existing technology, provides a kind of reinforced non-layered terylene long filament spun-bonded hot rolling non-woven fabric, to satisfy client's specific demand.
For achieving the above object, the not stratified enhancing terylene spun-bonded hot rolling non-woven fabric of the present invention is to be raw material with the long filament grade polyester chip, processes through high-temperature fusion, spinning, the drawing-off of air-flow tubular type, pendulum wire lapping and hot rolling reeling; It is characterized in that:
Described raw material is to be mixed by the polyester enhancing masterbatch of 0-5% (weight) and the long filament grade polyester chip of surplus;
When high-temperature fusion, the control screw extruder is respectively distinguished temperature and is respectively 275 ℃ in a district; Two district 283-286 ℃; Three district 288-292 ℃; Four district 292-295 ℃; Five district 290-293 ℃; Six district 289-292 ℃;
When spinning, spinning temperature is 287-292 ℃, and the spinning pump rotating speed is 18-24r/min;
When the drawing-off of air-flow tubular type, drawing-off air pressure is 4.8-5.2bar;
In hot-rolled process, milling train up-down rollers temperature is respectively 264-269 ℃ and 242-246 ℃, and roll left and right sides end pressure is respectively 12.5-13.2Mpa and 12.5-13.2Mpa, and the end intersection is respectively 18-23mm and 18-23mm about roll.
Need to prove:
1, in the crystallizing and drying operation, polyester need be strengthened the separately pre-crystallization of master batch, dry separately, then that drying is good master batch is poured in the Masterbatch drying chamber stand-by.Metering is then adjusted the weight and the adding proportion of two kinds of raw materials of Masterbatch machine according to measuring result and adding proportion.Starting the Masterbatch batch mixer mixes.
2, in the high-temperature fusion operation, it is relevant with the measuring pump rotating speed that screw extruder is respectively distinguished temperature, and it is high more that the big more temperature of measuring pump rotating speed needs, otherwise more little.
3, in spinning process, the measuring pump rotating speed is got over the high spinning temperature and is suitably improved.Since after adding polyester (PET) enhancing master batch, whole melt viscosity reduction, so the also corresponding reduction of spinning temperature, polyester (PET) enhancing master batch adding proportion is big more, and spinning temperature is low more, but must fluctuate about 5 kilograms by the assurance melt pressure.
4, in air-flow tubular type draft process, drawing-off air pressure reduces drawing-off pressure not twine milling train and be as the criterion because of the drawing-off deficiency causes as far as possible, and tow is not exclusively finalized the design, so that roll better, is difficult for layering.
5, in hot-rolled process, should heighten the temperature of top roll as far as possible, make to roll a little and roll, intersection and pressure also should be transferred greatly as far as possible, and certain simultaneously uniformity of noting whole cloth cover will cause the local delamination phenomenon as long as pressure is inhomogeneous.
It is 100-250g/m that processing technology of the present invention is fit to the processing substance
2The polyester filament spun-bonded hot rolling non-woven fabric.
Good effect of the present invention is: with polyester strengthen the section of master batch and long filament level polyester dacron evenly mixed after, again spinning technique and parameter are adjusted, make whole cloth cover roll a uniformity, clear, thereby effectively improve terylene non-woven fabric in length and breadth to brute force, powerful whole improve nearly 15-52%.Such as: the production substance is 140g/m
2Nonwoven fabric, when not adding polyester enhancing masterbatch, brute force only is 300N/5cm, when the polyester with the section of 98% long filament level polyester dacron and 2% strengthens master batch evenly mixing is as raw material, under the situation of adjusting process parameter, vertical powerful mean value can reach 352N/5cm, and brute force has improved 17.3%.Again such as, the production substance is 250g/m
2Nonwoven fabric, when not adding polyester and strengthen masterbatch, brute force only is 400N/5cm, when the polyester with the section of 97% long filament level polyester dacron and 5% strengthens master batch evenly mixing is as raw material, under the situation of adjusting process parameter, vertical powerful mean value can reach 609N/5cm, and brute force has improved 52%.No longer include lamination by optimizing each procedure technology parameter, make the polyester filament spun-bonded hot rolling non-woven fabric of producing, brute force has obtained large increase, obviously is different from conventional products, has satisfied client's instructions for use.
In order to verify good effect of the present invention, terylene spun-bonded (long filament) fabric hot rolled nonwoven fabrics of producing with processing technology of the present invention is detected, according to not stratified examination criteria testing result such as following table:
