Abstract
The utility model provides a kind of dust-filtering three dimensional fabric, comprise three-dimensional woven, described three-dimensional woven comprises at least two-layer weft yarn, is provided with one deck warp thread between adjacent two layers weft yarn, and warp thread and weft yarn are fixed together by bundled yarn, wherein, described weft yarn has two kinds, is respectively the first weft yarn and the second weft yarn, and the line density of the first weft yarn is higher than the line density of the second weft yarn, on thickness direction, the first weft yarn and the second weft yarn are arranged alternately.The utility model is simple in structure, and cost is low, weaves conveniently, and good filtration effect, is easy to Industry Promotion, can be for dust-filtering, and also can be for other filtration art such as waste water, waste oil.
Description
Technical field
The utility model relates to a kind of dust-filtering three dimensional fabric.
Background technology
Along with the development of industrial technology, discharge amount of exhaust gas increases, and dust granules too high levels in air is brought and had a strong impact on for the health of people's life.Dust granules is also one of key factor of the impact safety in production of a lot of production scenes and employee's life and health.Therefore, the research and development of the dust-filtering material of low cost, high efficiency, good endurance are extremely important.
At present, dust-filtering fabric mainly contains non-weaving cloth, two-dimentional woven fabric, multilayer mixed goods and three dimensional fabric etc.Non-weaving cloth has cheap, and preparation is simple, and the large advantage of industrialization output, but because its inner pore passage structure can not, by preparation technology's control, be mostly bending blind hole, once cause being stopped up and cannot recoiling by dirt, can not continue to use.And nonwoven material poor mechanical property, easily deforms, also limit its service life limited.The porosity that common machine is weaved cotton cloth is that the deinterleaving method by changing filling yarn fineness and filling yarn is controlled, and be mostly through hole, but the aperture of woven fabric is generally larger, not strong to the interception capacity of particle; Be filtered particle and very easily interweave and point out accumulation and assemble at longitude and latitude, fabric pore is diminished, reduce filter efficiency.Multilayer mixed goods has the defect that easily occurs that layering causes filter effect to reduce.Three dimensional fabric mechanicalness is excellent, and overall performance is good, but due to the existence of bundled yarn, has obvious passage on its thickness direction, and strainability is affected.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, and overall performance is excellent, and thickness direction space is even, and barriering effect is good, the dust-filtering three dimensional fabric of long service life.
In order to achieve the above object, the utility model provides a kind of dust-filtering three dimensional fabric, comprise three-dimensional woven, described three-dimensional woven comprises at least two-layer weft yarn, between adjacent two layers weft yarn, be provided with one deck warp thread, warp thread and weft yarn are fixed together by bundled yarn, wherein, described weft yarn has two kinds, be respectively the first weft yarn and the second weft yarn, the line density of the first weft yarn is higher than the line density of the second weft yarn, the line density of the first weft yarn is 15tex-50tex, the line density of the second weft yarn is 5tex-15tex, on thickness direction, the first weft yarn and the second weft yarn are arranged alternately.
Preferably, in every layer of described weft yarn, the first weft yarn and the second weft yarn are arranged alternately.
Preferably, described warp thread, the first weft yarn, the second weft yarn and bundled yarn are made up of monofilament, multifilament, air deformation yarn, cladded yarn or the skin-core structure composite yarn of polyamide fibre, terylene or polypropylene fibre.
Preferably, described three-dimensional woven is three-dimensional orthogonal woven structure.
Preferably, the thread count of described three-dimensional woven be 10-20 root/centimetre.
Compared with prior art, the beneficial effects of the utility model are:
Fabric construction densification of the present utility model, good integrity, is straight configuration through weft yarn, and fabric is not yielding, long service life; Intermeshing between the adjacent weft that in fabric, thickness is different, be staggered, thereby fabric construction densification and thickness direction are realized uniform space dust are played to effective iris action.Fabric is three-dimensional woven multilayer integrative-structure, fabric layers, and yarn variety, line density and thread count can regulate according to wanted Chalk-dust filtering granular size.The utility model is simple in structure, and cost is low, weaves conveniently, and good filtration effect, is easy to Industry Promotion, can be for dust-filtering, and also can be for other filtration art such as waste water, waste oil.
Brief description of the drawings
Fig. 1 is dust-filtering three dimensional fabric structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples to the new step explanation of the utility model;
Embodiment
As shown in Figure 1, for dust-filtering three dimensional fabric structural representation, described dust-filtering three dimensional fabric comprises three-dimensional orthogonal woven structure, described three-dimensional orthogonal woven structure is altogether five layers, comprise two-layer warp triple layer weft yarn, between adjacent two layers weft yarn, be provided with one deck warp thread 3, warp thread 3 and weft yarn are fixed together by bundled yarn 2, described weft yarn has two kinds, be respectively the first weft yarn 1 and the second weft yarn 4, selecting line density is that the nylon monofilament of 10tex is as warp thread 3 and bundled yarn 2, selecting line density is that the polyamide fibre air deformation yarn of 5tex and 15tex is respectively the second weft yarn 4 and the first weft yarn 1, on thickness direction, the first weft yarn and the second weft yarn are arranged alternately, in every layer of weft yarn, the first weft yarn and the second weft yarn are arranged alternately.Fabric is weaved on three-dimensional orthogonal loom.The thread count of fabric is 24 pieces/centimetre, and Fabric Design width is 30 centimetres, 30 centimetres of length.Described dust-filtering three dimensional fabric is for filtering the dust of diameter >10 micron.
Weaving process:
First, adopt two wefting insertion technique, in a weft inserting apparatus (being made as weft inserting apparatus A), odd-level weft yarn is the second weft yarn 2, and even level weft yarn is the first weft yarn 1; Odd-level weft yarn corresponding in another weft inserting apparatus (being made as weft inserting apparatus B) is the first weft yarn 1, and even level weft yarn is the second weft yarn 2.
While weaving, first use weft inserting apparatus A wefting insertion yarn, bundled yarn 2 interweaves, and makes the warp thread 3 of other layers, weft yarn as a whole with 2 one-tenth of bundled yarns, beat up, stepper motor batches, and re-uses weft inserting apparatus B wefting insertion yarn, and bundled yarn 2 interweaves, beat up, stepper motor batches, and completes weaving of a complete cycle.According to actual needs, control the length of fabric by controlling weaving cycle number.When weaving after the length of 30 centimetres, three-dimensional dust-filtering fabric knitting is complete.
