Description

A kind of thin paper machine woollen blanket

Technical field

The utility model relates to pulp technology for making paper more particularly to a kind of thin paper machine woollen blankets.

Background technique

In paper technology, in order to slough the water in wet web, existing paper machine usually has wet end, press section and does Dry portion.These parts, the direction setting transmitted along wherein wet web by the sequence of wet end, press section and drying section.Work as wet web When passing through the equipment that another is arranged according to wet end, press section and drying section from a paper making equipment, side transmission, while being taken off Water is finally dried in drying section.

China Patent No.: 200920351393.5 disclose a kind of Multi-layer wide-amplitude pressing paper-making felt from top to bottom successively by Base cloth layer, reverse side flocking layer, surface flocking layer and internal layer flocking layer etc. composition, it is characterized in that base cloth layer by three layers or more warps with The strong fabric layer that weft is woven into the thickening, reinforcement of an entirety is constituted, above and below the base fabric with paper machine running contact Two sides is implanted into the dedicated nylon fibre layer of felt of two layers of different fibre diameter, the upper layer of base fabric on needled flocking machine respectively Warp is the fiber wool-like yarn with certain elasticity, and lower layer's warp is polyamide fibre strand, and the weft of base fabric is chinlon filament monofilament；Through item Breaking strength reaches 4500-6500N/5cm, and latitude item breaking strength reaches 1800-3000N/5cm, and Air permenbility reaches 400-1100mm/s.Base Layer of cloth is woven into the strong fabric layer structure of the thickening, reinforcement of an entirety by being arranged by three layers or more warp and weft, is produced Woollen blanket recovery it is good, intensity is high, water separation capability is strong, surface without felt mark, improve into the quality of paper.

But in the paper making process, need woollen blanket that can more effectively squeeze out the moisture in wet web.It is used for the first time in woollen blanket The squeezing outlet capacity of woollen blanket is kept also to be important for a long time afterwards.The origin of these demands be in a paper machine woollen blanket by repeatedly Ground squeezes, and therefore, the function of squeezing water gradually deteriorates.And want to extend the service life of woollen blanket, hair is kept before woollen blanket is replaced It is also important in blanket with enough abilities for squeezing water.In order to squeeze the water out from paper web, woollen blanket is suitable for passing through paper machine Pressure section.It must also pass through the pressure section of a cleaning device.Woollen blanket per pass presses section, is all extruded.Although section is pressed to apply It gives woollen blanket pressure, but in order to keep its seepage of water, needs to keep the elasticity of woollen blanket.Hair is allowed due to woollen blanket natural resiliency The time that blanket reverts to its three-dimensional structure becomes very short.The variation of woollen blanket size becomes unavoidably, and detrimental effect is hair Blanket loses stability at runtime, and even if it is expected that its service life is about 40 days, squeezing is also showed that in several days The deterioration of outlet capacity.

Utility model content

Therefore, for above-mentioned problem, the utility model provides a kind of thin paper machine woollen blanket, it mainly solves existing skill The stability of paper machine woollen blanket is poor in art, and Zhashui ability deteriorates fastly, and woollen blanket is caused to replace frequent problem.

To achieve the above object, the utility model uses following technical scheme: a kind of thin paper machine woollen blanket, including warp knit Made of base, the upper surface of the base is provided with upper fibrage, and the surface of the upper fibrage is provided with reverse side flocking layer, The lower surface of the base is provided with high water absorption layer, and the lower surface of the high water absorption layer is provided with lower fibrage, the high water absorption Layer includes the upper and lower, and the upper layer includes several upper wefts arranged side by side, is wound on each upper weft Coiling is serially connected with warp on each upper winding line, and the lower layer includes several lower warps arranged side by side, each described It is wound with lower winding line on lower warp, is serially connected with lower weft on each lower winding line, the upper and lower pass through yarn It is staggered and is intertwined and connected across upper warp and lower warp.

Further, the upper winding line and lower winding line are that high hydroscopic resin is made.

Further, the upper fibrage and lower fibrage are pierced by needle is respectively arranged with upper through-hole and lower through-hole, described The diameter of upper through-hole is less than the diameter of lower through-hole.

Further, the reverse side flocking layer is laid with by the short fibre of cotton synthetic fibre.

By using preceding solution, the beneficial effects of the utility model are: the utility model paper machine woollen blanket, high by setting Water absorption layer increases the water absorbing properties of woollen blanket, for quickly absorbing the moisture on wet web, and increases the stability of woollen blanket, makes It obtains woollen blanket and keeps higher Zhashui ability in extrusion process repeatedly, increase service life, reduce the replacement frequency of woollen blanket；It is logical It crosses upper winding line and lower winding line made of high hydroscopic resin to be respectively wound around on weft and lower warp, so that the upper and lower The surface layer of double-deck high-hydroscopicity energy is formed, and is staggered by yarn and is intertwined and connected across upper warp and lower warp, so that on The high water absorption layer of layer and lower layer's setting layer closely connects, and the tightness and stability of woollen blanket is improved, so that woollen blanket is repeatedly Higher Zhashui ability is kept in extrusion process；Further, upper fibrage and lower fibrage are respectively arranged with by needle thorn Through-hole and lower through-hole, the diameter of upper through-hole are less than the diameter of lower through-hole, and the upper through-hole of small-bore is added by the effect of high water absorption layer The water absorbing capacity of fast woollen blanket, and being distributed in for uniform moisture winds on line and lower winding line.Line is wound in increase to twine under Moisture is quickly discharged by lower through-hole in extrusion process in the service life of coiling, realizes efficient Zhashui ability.
