In the current domestic and international polyester staple fiber tow process for cooling, interior ring blow moulding (adopting circular spinnerets, cooling air outwards to be blown by the center) is divided into the form of high damping and two kinds of blowings of superelevation damping:
(1) polyester staple fiber tow process for cooling has ring blow moulding in the high damping, ring blow moulding in the superelevation damping.Between 4000pa.s～5000pa.s, a blowing rectification tube is micropore sintered metal cylinder to the ring blow moulding to the cooling air air main blast of molten polyester cooling curing in the high damping.This rectification tube complex manufacturing technology of drying, in 1～2 year service life, one-time investment quite high (be equivalent to the technology of the present invention 100 times) need purge with high pressure air during cleaning.
(2) between 6000pa.s～10000pa.s, a blowing rectification tube adds porous metals rectification tube for high molecular foam material to the interior ring of employing superelevation damping blow moulding to the cooling air air main blast of molten polyester cooling curing.This complex manufacturing technology of drying, high molecular foam material are the imported material of a kind of " with promptly abandon ", and in service life short (10～20 days), cost of investment height (be equivalent to the technology of the present invention 10 times) need add clear water with cleaning agent during cleaning.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of Preparation method of low damping inner loop porously fibrous for the above-mentioned defective that solves prior art.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of Preparation method of low damping inner loop porously fibrous, its polyester fondant with inherent viscosity 0.63～0.65 is that raw material carries out in the fiber manufacture process, other steps in adopting prior art, interior ring blow moulding also has the cooling air air main blast≤2500pa.s through a blowing rectification tube, a blowing rectification tube adds porous metals rectification tube for woven wire, spinnerets hole count 〉=3701～4620, blowing wind speed 0.8～2m/s, blowing rectification tube inlet pressure 1500～1800pa.s, 1200pa.s falls in rectification pressure, the feature of Blowing drum blast 200～350pa.s.
The structure and the material of a described blowing rectification tube are: the woven wire material is a stainless steel, wire twine footpath 0.05～1mm, several 30～70 orders of wire net mesh; Porous metals rectification tube material is a stainless steel, plate thickness 1～3mm, and perforate aperture 1～3mm, percent opening 10～30%, open-cellular form is for evenly distributing from top to bottom; Length 400～the 700mm of rectification tube.
The blowing manufacture craft that the present invention adopts is simple, adopts common clear water to clean and adds common compressed air purging, and service life, one-time investment was low more than 2 years, and the simple expense of service procedure is low.
The invention has the advantages that: (1) low resistance process route, air-conditioning system can be selected fan with low voltage for use, has reduced the voltage withstand class of airduct, and the equipment investment of whole system is reduced; (2) the unit attaching capacity of air-conditioning draught fan reduces, and air-conditioning technology chilled water amount reduces, and the material consumption energy consumption greatly reduces; (3) the production equipment requirement is low, and the product-specific investments cost reduces, and increases economic efficiency.Ring blows the porous polyester staple fibre and has product top grade rate height in the low resistance that makes with this method, quality such as maintain the leading position among the colleague at home, and also production run is stable.
