Abstract
The utility model relates to polyester staple fiber with pentagonal cross section, and belongs to special-shaped fiber. The polyester staple fiber with the pentagonal cross section comprises a fiber body and bulges, and is characterized in that the cross section of the fiber body and those of the bulges take the shape of pentagrams, and the denier of the fiber is 6D-25D. The polyester staple fiber has the advantages of reasonable structural design, and high penetrability, air permeability and capability of catching solid particles.
Description
Technical field
The utility model relates to a kind of pentagon cross section polyester staple fiber, belongs to a kind of profiled filament.
Background technology
In the increase of the continuous progress of science and technology and the market demand, chemical fibre industry fast development both domestic and external.Simultaneously; countries in the world are for the protection of environment and the cycling and reutilization of limited goods and materials; to improve atmosphere, water system environment, reach the consideration of environmental issues such as energy-saving and emission-reduction, for smoke filtration, air filtration, water filtration and brewage filtering materials such as filtration and further investigate.The use of polyester staple fiber on the filtering material of non-weaving cloth also more and more widely.
Because filtering material in use will be considered the factors such as capturing ability of its permeability, gas permeability, solids, thereby the selection to fiber is important when making the nonwoven fabric filter material.The nonwoven fabric filter material of exploitation early mainly uses the circular-section terylene staple fibre of 2D-15D, the filter material of this circular cross-section, the common not enough problem of permeability that exists.For solving permeability, the gas permeability of filter material, method commonly used is to use the relatively slightly fiber of a bit, though can make the permeability of this filter material, gas permeability increase like this, its solids capturing ability descends.Have in the market that filter material is compound therewith by the material with medium or different medium, improving its capturing ability, but this method can make production cost increase.
Demand for the permeability, gas permeability and the solids capturing ability that satisfy the non-weaving cloth filter material simultaneously, begin on the market by using fiber cross section heteromorphosis to solve this problem, have and use the terylene chemical fibre of trilobal, triangle, circular hollow to make filter material, make its performance improved.But the effect of improving is limited.
Summary of the invention
Technical problem to be solved in the utility model provides the good pentagon cross section polyester staple fiber of capturing ability of a kind of reasonable in design, good penetrability, good permeability, solids.
It is this pentagon cross section polyester staple fiber that the utility model solves the problems of the technologies described above the technical scheme that is adopted, and is made up of fiber bodies and projection, is characterized in: the cross section of described fiber bodies and projection is pentalpha, and the fiber number of fiber is 6D-25D.
The length on each limit of pentalpha described in the utility model is identical.
The shape size on each limit of pentalpha described in the utility model is identical.
The utility model is compared with prior art and had the following advantages and effect: the utility model provides a kind of pentagon cross section polyester staple fiber that is used for filtering material, this fiber characteristics is that the cross section is " five-pointed star " shape, each blade all symmetrically, improve the bulking intensity and the hole quantity of the material of nonwoven fabric, improving gas permeability, infiltrative while, improving the solids capturing ability.The nonwoven fabric filter material that this fiber is made has good embodiment in the seizure of permeability, gas permeability, solids.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment has been described a kind of pentagon cross section polyester staple fiber that is used for filtering material, form by fiber bodies 1 and projection 2, the cross section of fiber bodies 1 and projection 2 is a pentalpha, by the projection 2 five angles forming be evenly distributed in fiber bodies 1 around, the size at each angle is all identical with shape.In the present embodiment, the fineness of fiber is 6D.
The utility model, the fineness of fiber can also be adjusted into 6D or 25D as required.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
