Description

HMLS type dacron ultrafine fiber woven filter cloth

Technical field

It the utility model is related to filter cloth field, more particularly to HMLS type dacron ultrafine fiber woven filter cloth.

Background technology

Industrial filter cloth is the filter medium being fabricated by natural fiber and synthetic fibers, is mainly used in separation of solid and liquid and work Industry dedusting, it is additionally operable to separation of solid and liquid, gas solid separation；Gas solid separation.Traditional terylene filter cloth has intensity higher, has certain resistance to Corrosivity.But it is poor to equally exist particle fissility, the shortcomings of antistatic behaviour difference.

Utility model content

The utility model is directed to the problems of the prior art, there is provided HMLS type dacron ultrafine fiber woven filter cloth.

In order to solve above-mentioned technical problem, the utility model is addressed by following technical proposals：

HMLS type dacron ultrafine fiber woven filter cloth, including the filter layer on top layer and the branch that is arranged on the downside of filter layer Support layer, filter layer and supporting layer and filter cloth is formed by interlacing point weaving connection, filter layer is mutually heavy by table warp thread and outer weft yarn Floating to be formed, the institutional framework of filter layer is twill-weave；Supporting layer is mutually risen and fallen and formed by back warp yarn and back weft yarn, supporting layer Institutional framework be plain weave；The material of table warp thread and back warp yarn is HMLS type ultra-fine polyester fiber, outer weft yarn and inner The material of weft yarn is terylene short fiber.

Preferably, the fiber number of table warp thread and back warp yarn is 1300 Denier, table warp thread and back warp yarn are 144 and ultra-fine washed The terylene HMLS type dacron thread of synthetic fibre fibre single thread composition, there is sth. made by twisting；The thread count of filter layer and supporting layer is 80 × 24.Carry The F numbers of high HMLS Polyester, and before warping technology, to carrying out heat treatment through wire material, ensure the smoothness of material, Reduce the generation of fault in weaving process.From larger F numbers, the organizine for enabling to be twisted has larger bulkiness, filter Cloth is overall more plentiful, and the interception capacity of debris is strengthened.

Preferably, the mass area ratio of filter cloth is 665~735g/ ㎡.

Preferably, the fiber number of superfine fibre is 1.5 Denier.Superfine fibre greatly reduces silk because fiber number is superfine Rigidity, the fabric feeling made is extremely soft, and fiber finer can also increase the layer structure of organizine, increases specific surface area and hair Thin effect, make it have good moisture absorption dissipates moist.And dacron ultrafine fiber has excellent intensity, dimensional stability is soft It is suitable.HMLS type polyester industrial yarn has the advantages that fracture strength is big, and modulus of elasticity is high, elongation percentage is low, impact resistance is good.

Preferably, the warp thread of filter cloth and the density of weft yarn are warp-wise：322/10cm, broadwise：94/10cm.Can More interlacing point is obtained, improves interception capacity of the filter cloth to debris.

Preferably, the twill-weave of filter layer is the twill-weave under two on two.Twill-weave have interlacing point it is fine and closely woven, The advantages that fabric strength is high, and the collection to fine particle can be stood the advantages that strong, filtering rate, and cake discharge ability is stronger.

Preferably, the cross section of table warp thread and back warp yarn is cylinder, the outer surface of table warp thread and latitude warp thread is provided with The surface of annular groove along the circumferential direction and translot along its length, table warp thread and back warp yarn obtains polytetrafluoroethyl-ne by impregnating Alkene film.Polyester monofilament improves the HMLS performance of filter cloth by the way of carbon fiber and dacron ultrafine fiber combination.Simultaneously Make filter screen that there is static electricity resistance, outside dipping poly tetrafluoroethylene causes polyester monofilament to obtain the performance of polytetrafluoroethylene (PTFE), such as carried The high temperature of environment workable for polyester monofilament filter cloth, while polytetrafluoroethylene (PTFE) has extremely low coefficient of friction, so as to reduce Filter cloth filter opening plugging rate, ensure that the filter efficiency of filter cloth, reduce wash number, while cake discharge is simpler.

Preferably, carbon fibre web is provided between filter layer and supporting layer.It is antistatic that carbon fibre web can have filter cloth Property, while carbon fibre web can provide intensity for the structure of filter screen, improve the anti-fold ability of filter screen.

The utility model uses above-mentioned technical proposal, has the advantages that：

(1) warp thread of filter screen uses HMLS ultra-fine polyester fiber, makes filter cloth feel extremely soft, and fiber finer can be with Increase the layer structure of organizine, increase specific surface area and capillary effect, make it have good moisture absorption dissipates moist.And terylene surpasses Fine fibre there is excellent intensity, dimensional stability, while filter cloth to have fracture strength is big, modulus of elasticity is high, elongation percentage is low, resistance to The advantages that punching property is good.The F numbers of HMLS Polyester are improved, and before warping technology, to carrying out heat treatment through wire material, are protected The smoothness of material is demonstrate,proved, reduces the generation of fault in weaving process.From larger F numbers, the organizine for enabling to be twisted has Larger bulkiness, filter cloth is overall more plentiful, and the interception capacity of debris is strengthened.

(2) filter layer has that interlacing point is fine and closely woven, fabric strength is high using twill-weave, and the collection to fine particle can be stood by force The advantages that, filtering rate, the advantages that cake discharge ability is stronger.There is longer service life simultaneously.And supporting layer uses plain weave Tissue, plain weave have intertwined point is more, quality is strong, endure scrape, surfacing, more frivolous wearability is good, good permeability, energy It is enough to provide reliable support and wearability to filter cloth, increase the service life of filter cloth.

(3) broadwise uses polyester staple fiber, and being relatively used long fibre has more preferable filter effect.Warp-wise is using ultra-fine simultaneously The polyester fiber yarn of polyester fiber composition is overcome using the unconspicuous shortcoming of polyester staple fiber filter cloth ash-removal effect, while high Mould low-shrinkage superfine fibre filter cloth has stretch-proof, Stability Analysis of Structures and filter efficiency etc. multi-functional in one, compared with ordinary polyester filter cloth Performance tool has greatly improved.

(4) outer surface of table warp thread and back warp yarn is provided with poly tetrafluoroethylene, and poly tetrafluoroethylene can be by opening up Annular groove and translot be tightly attached to the outer surface of table warp thread and back warp yarn.So that filter cloth obtains the phase of poly tetrafluoroethylene Performance is closed, improves the acid resistance and alkali resistance of filter cloth.Meanwhile polytetrafluoroethylene (PTFE) has resistant to elevated temperatures feature, the resistance of filter cloth is improved Combustion property, and because its coefficient of friction is extremely low, so the blocking rate of filter opening is relatively low, so as to reduce cleaning frequency.
