Specific embodiment
For further illustrating the technological means and its effect that the utility model taken, below in conjunction with of the present utility model
Embodiment and its accompanying drawing are described in detail.
With reference to Fig. 1, Fig. 1 is that a kind of flow process of the manufacture method first embodiment of the utility model double ends flat filament dry net is shown
It is intended to.In this embodiment, the manufacture method of double ends flat filament dry net includes：
S100 adopts the first warp and the first parallel intertexture to form paper forming layer；
S200 adopts the second warp and the second parallel intertexture to form machine level.
S100 forms paper forming layer step using the first warp and the first parallel intertexture and specifically includes：
S120 adopts the first warp and the first parallel to pass through at least two weaves intertextures and form paper forming layer.
S200 forms machine level step using the second warp and the second parallel intertexture and includes：
S220 adopts the second warp and the second parallel at least two weave intertexture to form machine level.
In the above-described embodiments, by arranging the first warp and the second warp, increased the contact area with page, make paper
Page becomes paper effect good, does not have wire mark, and Longitudinal extending is minimum, long service life；And the first parallel and the second parallel are set, make to do
Between the two-layer up and down of dry net, the changing of the relative positions reduces, and does not have inter deterioration, wearability is improved, simultaneously under paper machine maximum tension
Run and do not extend and bounce back, stability is strengthened, and service life is longer.
Optionally, at least two weaves at least include plain weave weave, satin weave method and twill weave method.
Wherein, average pattern fabric:Tabby warp thread and weft yarn are interweaved with rule one on the other.Namely through weft yarn
Just interlock once every a yarn, so intertwined point is at most, yarn flexing point at most, makes fabric strong, wear-resisting, stiffening, smooth,
But elasticity is less, gloss is general, and plain cloth density can not possibly be too high, more frivolous, and preferably, gas permeability is preferable for wearability.
Twills:Three warp thread and three weft yarns at least to be had in one complete organization to be interweaved, every warp thread latitude
One latitude can only be had on yarn through interlacing point.In fabric face, oblique lines is constituted by continuous interlacing point.Twill-weave is by warp
Float long line or latitude floats the appearance effect that long line constitutes the twill that fabric face presents.The number of times ratio of twill warp and weft interweaving
Plain weave is few, be through weft yarn between hole less, it is closeer that yarn can arrange, thus fabric is dense abundant.Twill is relatively
Plain cloth is soft, and elasticity is good.But due to twills, to float long line longer, through weft yarn thickness, density identical condition
Under, wearability, fastness are not so good as plain cloth.Cloth cover has substantially oblique lines, feel, gloss, elasticity preferable.
Satin weave refers to that warp (or parallel) flotation line is longer, and intertwined point is less, though they form oblique lines, is not continuous
, separation distance from each other is regular and uniform, and this fabric construction form is referred to as satin weave.The floating long line of satin fabric is longer,
Fastness is also worst, but soft texture, and silk fabric face is smooth, gloss might as well, the richest and the most honour magnificent, therefore apply very wide in fabric.As
What the ground tissue in the flower tissues such as tapestry satin, flower soft silk adopted is all satin weave.Satin organizational structure's figure satin face generally refers to
Fabric reflects the one side more than warp-wise raw material：As color fourth warp-wise bright yarn, then I cries it at ordinary times in that face of good luster is satin face,
Satin weave is different from plain weave and twill is to reach the standard grade, and wire jumper is longer, and twill angle is less, and gloss is higher, more smooth, more attractive,
But shortcoming is easily to cut silk to pieces although smooth not soft.
With continued reference to Fig. 1, the step before S100 interweaves formation paper forming layer using the first warp and the first parallel is also wrapped
Include：
S020 wire rod is checked：Examined item by item through footpath, pyrocondensation, tensile strength, acid-alkali-resistant degree index according to what the production schedule required
Test, and inspected by random samples in batches or full inspection according to concrete production requirement；
S040 warping：Make each monofilament even tension consistent by external force；
Step after S200 interweaves formation machine level using the second warp and the second parallel includes：
S300, tests net：Woven webs are carried out with Pre-testing, processes dictyosome flaw, the registration of market of going forward side by side condition, carry for rationally cutting net
For foundation；
One-step building：Sizing faller speed, heating-up temperature are arranged according to the number of turns, longitudinal tension force is multiplied by according to net width and sets
Definite value, calculates longitudinal total tension input forming machine and carries out stretching control, horizontal tentering device is carried out by setting value input forming machine
Shrink and control, make net after shaping, reach regulation elongation, shrink and stability that is ventilative, improving net and service life；
S400 cuts out net：Cut net by the net type of user's requirement, ventilative, specification, have to before cutting net be entered according to production work ticket
The strict preliminary examination of row, avoids problematic dictyosome, rationally spells and cuts it is ensured that becoming net rate；
S500 grafting：By grafting operation, the parallel of one fixed width of being dismantled in the dictyosome cutting two ends, respectively by helical ring
Weave enter in dictyosome, finally by helical ring, net is coupled together with special connecting line；
Bis- sizings of S600：The main socket that processes of secondary sizing is smooth, and upper machine fortune turns around, and network interface is smooth；
S700 product inspection：With reference to polyester webs professional standard GB/T26455-2011, rechecked, length and width, thoroughly comprehensively
Gas, through close, filling density, net flatness, joint strength etc.；
S800 packaging and storage, packing case is pressed specification and is customized, and wears silk, the quality certification, puts into by regulation, and packing case outward appearance model is advised
Lattice, direction, protection against the tide indicate, handle with care etc. that mark is clear.
