Abstract
The invention discloses a profiled-yarn drying net for papermaking, which comprises a system warp and two system wefts. The warp is interwoven with a first system weft to form the front surface of a fabric. The warp is interwoven with a second system weft to form the back surface of the fabric. The two system wefts are formed by two different kinds of filaments with different cross section shapes, and the weave structure of the two system wefts is called as 'weft backed weave'. The warp is a profiled yarn, the first system weft is a profiled yarn and the second system weft is a round yarn. The cross section of the profiled yarn is rectangular and the cross section of the round yarn is round. Based on the profiled-yarn drying net, since the round filament of the first system weft is changed to the profiled yarn and the warp is interwoven with the first system weft to form the front surface of the fabric, i.e. the paper attaching surface of the drying net, the invention has the advantages that the contact area between the surface of the filaments and paper accounts for approximately 60-70 percent of the surface area of the filaments, the net surface flatness is good, the thickness of the profiled-yarn drying net is reduced, the change of water vapor condensation is reduced when the water vapor passes through the drying net, and the drying efficiency is effectively improved.
Description
Technical field
The present invention relates to profiled-yarn drying net for papermaking, a kind of drying section of paper machine that is applied in of saying so more specifically plays oven dry and supports the filling-backed weave profiled-yarn drying net for papermaking that transmits page.
Background technology
The paper grade (stock) dry net is the essential valuable dehydration equipment of papermaking enterprise, is applied in drying section of paper machine, plays oven dry and supports the transmission page.
Fast development and paper quality requirement raising along with paper industry, paper industry is more and more higher to the quality requirement of paper grade (stock) dry net, Papermaking fabric industry technology personnel are according to the requirement of paper industry, constantly explore, research and develop novel paper grade (stock) dehydration equipment, constantly satisfy the needs of paper industry.
Produce round yarn drying net since the eighties in 20th century, substituted traditional papermaking dryer felt, improved the drying efficiency and the service life of Papermaking fabric greatly.To 20 end of the centurys, development along with paper industry, the paper motor speed is more and more faster, and paper quality requires more and more higher, and circle yarn drying net and page contact-making surface are point-like, contact area is little, easily form wire mark on the page, round simultaneously yarn drying net adopts common monofilament production, and the endurance of monofilament and hydrolytic resistance can be poor, service life is short, therefore is difficult to satisfy the demand of paper industry fast development.Papermaking fabric industry technology personnel are according to the demand of paper industry, developed profiled-yarn drying net, warp adopts shaped filaments, the monofilament cross section is a rectangle, and monofilament surface and page contact-making surface are planar, and contact area is big, page does not have wire mark or wire mark is light, monofilament has the high anti-hydrolysis performance simultaneously, and endurance and hydrolytic resistance can be good, long service life.Since 21 century, the paper industry develop rapidly, develop into paper machine speed above 2000 meters/minute from km speed of a motor vehicle paper machine, the continuous increase of paper machine speed, requirement to Papermaking fabric also improves constantly, the paper grade (stock) dry net is no exception, and it is extremely urgent to satisfy the develop rapidly of papermaking paper industry to develop new profiled-yarn drying net.
Traditional profiled-yarn drying net adopts system's warp and two system's parallels, the parallel of two systems all is a circular monofilaments, warp be interspersed in two-layer up and down between, flexibility is big, monofilament surface and page contact area account for monofilament surface long-pending about 50%, do not reach the contact area maximization fully, still have bigger room for promotion.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of profiled-yarn drying net for papermaking at problems of the prior art, its objective is the contact area that improves monofilament surface and page, thereby improve the wire side flatness, and the air permeability performance of dry net and hydrolytic resistance energy, the service life of prolongation dry net.
For solving the problems of the technologies described above, the technical solution used in the present invention is: this kind profiled-yarn drying net comprises system's warp and two system's parallels, warp and first system's parallel interweave and form the front of fabric, warp and second system's parallel interweave and form the reverse side of fabric, two system's parallels are made up of two kinds of difformity cross section monofilament, and its institutional framework is called " filling-backed weave ".
Described warp is a shaped filaments, and first system's parallel is a shaped filaments, and second system's parallel is the circle silk, and the cross section of shaped filaments is a rectangle, and the cross section of circle silk is circular.
Described first system's parallel quantity is 1: 1 with the ratio of second system's parallel quantity.
The sectional dimension of described warp can be identical with first system's parallel sectional dimension, also can be different.
Described warp adopts the high anti-hydrolysis monofilament polyester, and first system's parallel adopts high anti-hydrolysis monofilament polyester or non-anti-hydrolysis monofilament polyester, and second system's parallel adopts high anti-hydrolysis monofilament polyester or non-anti-hydrolysis monofilament polyester.
The raw material monofilament of described profiled-yarn drying net for papermaking is high anti-hydrolysis monofilament polyester or non-anti-hydrolysis monofilament polyester, also can be polyether-ether-ketone (PEEK) or polyphenylene sulfide (PPS), and the cross section of raw material monofilament is rectangle or circle.
A kind of profiled-yarn drying net for papermaking with above-mentioned special construction has the following advantages:
1, this kind profiled-yarn drying net for papermaking is on the profiled-yarn drying net production basis, first system's parallel circular monofilaments is adjusted into shaped filaments, warp and first system's parallel interweave and form the front of fabric, be the paster face of dry net, monofilament surface and page contact area account for about the long-pending 60-70% of monofilament surface, and the wire side flatness is good, and reduced the thickness of profiled-yarn drying net, when steam passes through profiled-yarn drying net, reduce the chance of water vapor condensation, can effectively improve drying efficiency.
2, the warp of this kind profiled-yarn drying net for papermaking and second system's parallel interweave and form the reverse side of fabric, i.e. the subsides cylinder face of dry net.Drying section at the paper machine, put dry net on the drying cylinder, dry net and page form " drying cylinder bag district ", " drying cylinder bag district " seals except that two ends basically, " drying cylinder bag district " obtains good bag area ventilation along with the rising of dry net air permeability, and evaporation rate is greatly improved, and monofilament has the high anti-hydrolysis performance simultaneously, endurance and hydrolytic resistance can be good, long service life.
