Abstract
The multifilamentary filter cloth is formed by interweaving multifilamentary long-fiber polypropylene warps and long-fiber polypropylene wefts in a variable mode. The innovative weaving method comprises the following steps: 4/4 change interweaving method is adopted, that is, one circulation arrangement mode of the warp and the weft is that four warp are positioned at the upper layer of the weft, four warp are positioned at the lower layer of the weft, and one weft is advanced when two adjacent warp are changed up and down; the weaving equipment used was: the denier P1 type rapier loom can change varieties rapidly; the types and materials of the adopted silk threads are as follows: the multifilament long fiber polypropylene warp yarn is 500D (145T/S) and has a density of 560 pieces/10 cm, and the multifilament long fiber polypropylene weft yarn is 840D untwisted and has a density of 200 pieces/10 cm. The multifilament filter cloth has the advantages of good permeability, high filtering speed, good regeneration performance, easy cake removal and cleaning, good chemical and mechanical properties, durability and the like, and is suitable for a filter press to filter 5 mu m tiny particle materials with higher viscosity.
Description
Technical Field
The utility model belongs to the technical field of the weaving of industry filter cloth, a multifilament filter cloth that change that filter press was used was interweaved is related to.
Background
The filter press is a general intermittent operation pressure filtration device, and is suitable for solid-liquid separation of various suspensions. The filter cloth is a core element of the filter press, and the performance of the filter cloth (including trapping, permeation, regeneration, physical and chemical properties and mechanical properties) determines the precision and filtration rate of solid-liquid separation, and also directly influences the production capacity and power consumption of the filter press.
The silk thread type of the textile filter cloth is divided into monofilament (one silk) and multifilament (woven by forming one silk by a plurality of fibers); the monofilament filter cloth is a new generation of filter medium, has high filtering efficiency, easy cleaning and high strength, but has poor trapping capability; the multifilament filter cloth is a common filter medium, has strong trapping capacity and is suitable for filtering small-particle materials. The silk thread material of the filter cloth is mostly synthetic fiber polypropylene fiber, terylene, chinlon and the like, the polypropylene fiber has better permeability and regeneration performance, the terylene has better trapping and physical and chemical properties, and the chinlon has better mechanical property. The weaving method of the filter cloth comprises the following steps: plain weave, twill weave, satin weave, non-woven needle-punched molding; the air permeability of the plain filter cloth is poor; the twill filter cloth has high porosity and good air permeability; the satin filter cloth is smooth and has the best air permeability, and is respectively suitable for filtering different materials.
The multifilament filter cloth woven by the existing weaving method has the following defects that the weft (the thread vertical to the selvedge) is a short fiber silk thread: the cloth cover has more hairiness and is not smooth enough, and when small-particle materials with higher filtering viscosity are applied, the permeability is poor, the filtering speed is low, the regeneration performance is poor, and cakes are not easy to fall off; the mechanical property is poor, the product is easy to damage and not durable, and the service life is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defect of current multifilament filter cloth, solving corresponding technical problem, providing a long fiber multifilament filter cloth that changes interweaving.
The true bookThe technical scheme adopted for solving the problems in the prior art is that the variably-interwoven multifilament filter cloth is formed by interweaving warp yarns (warps) and weft yarns (wefts) in a variable mode, and the cloth surface is twill, and is characterized in that the conventional weaving method is improved to be 4/4 variably-interwoven method, namely, four warp yarns are positioned on the upper layer of the weft yarns in a circulating arrangement mode, four warp yarns are positioned on the lower layer of the weft yarns, one weft yarn is advanced when two adjacent warp yarns are vertically changed, the multifilament filter cloth adopts multifilament yarns in the type of silk yarns, the warp yarns of the multifilament filter cloth are 500D (145T/S) and the density of the multifilament filter cloth is 560/10 cm, the multifilament filter cloth is 840D untwisted and the density of the multifilament filter cloth is 200/10 cm, and the variably-interwoven multifilament filter cloth has the air permeability of (8-11) L2The filter has smooth cloth surface, less hairiness, good permeability and high filtering speed between/S, and is suitable for a filter press to filter 5 mu m micro-particle materials with higher viscosity.
Furthermore, the weft yarns are yarns vertical to the selvedge, the existing short fiber yarns are changed into long fiber yarns, and the long fiber yarns have good mechanical properties, can bear higher tension, and are durable and long in service life.
Furthermore, the warp yarns and the weft yarns are all made of polypropylene fiber materials, and the woven multifilament filter cloth has a matte layer, smooth cloth surface, good regeneration performance, easy cleaning and easy cake removal.
The utility model provides a multifilament filter cloth that change was interweaved has advantages such as the permeability is good, filter speed is fast, the regeneration property is good, take off the cake easily and wash, chemistry and mechanical properties are good, durable, has both improved the performance of filter cloth, has prolonged the life of filter cloth again.
