Description

TECHNICAL FIELD The present invention relates to a material used as a cartridge filter for removing impurity particles in a liquid such as water, a solvent, oil or a gas such as air.

2. Description of the Related Art Cartridge filters generally have a hollow cylindrical bobbin that has a structure in which fiber yarns are laminated and wound to form a fiber layer having a large number of continuous holes, and are used in various fields as water treatment and other materials. Has been done. The passing mechanism is, for example, in water treatment, when raw water passes through a fiber layer having a large number of continuous pores formed by laminating and winding from the outer peripheral surface toward the perforated bobbin, impurity particles are trapped and filtered. The treated and overtreated clear water is collected through a perforated bobbin. For this reason, the performance of the material largely depends on the material and shape of the fiber yarn to be wound in layers.

Conventional materials of this type include synthetic fiber multifilaments that have undergone special bulky processing and synthetic fiber nonwovens that have been pleated in order to create a density gradient in the laminated fiber layers. Many are used.

Problems to be solved by the invention As described above, the material used for the cartridge filter is
It is specially processed for a cartridge filter, and although it is sufficiently satisfactory in overperformance, it requires special processing and is mainly costly as a disposable cartridge filter.

The present invention solves the above problems, and an object thereof is to provide an inexpensive material having excellent performance.

Means for Solving the Problems In order to solve the above-mentioned problems, the material of the present invention is obtained by winding a twisted end selvage of an auxiliary selvage yarn when weaving with a shuttleless loom around a bobbin with holes. It is characterized by that.

The material of the present invention uses the waste selvage of the auxiliary selvage yarn generated during weaving by the shuttleless loom, but the auxiliary selvage yarn used when weaving by the shuttleless loom such as the water jet loom or the air jet loom is It is provided separately from the woven fabric structure in order to adjust the tension of the weft during weaving. Generally, several warps are prepared separately from the weave structure, and the weft ends are textured with this warp to form auxiliary selvage during weaving, and this auxiliary selvage is twisted by rotation to adjust the weft tension. . The auxiliary selvage yarn is separated from the main body of the fabric by cutting the weft yarn with a heat cutter after weaving, and has been conventionally discarded as a selvage yarn.

Action In the above configuration, the auxiliary selvage of the auxiliary selvage in the shuttleless loom to be wound around the perforated bobbin is composed of several warps and wefts and has a large excess area, and is twisted and cut at the time of weaving Since it becomes a throw-off ear, it is sublime due to the entanglement of the warp and weft, and the weft protrudes like a pile on the surface,
As a material, it has a high collection efficiency of impurity particles, and is extremely inexpensive because it has been conventionally disposed of.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic plan view of a part of the material of one embodiment of the present invention with a part cut away, FIG. 2 is a schematic configuration diagram of the main part of the selvage of auxiliary selvage used in the material, and FIG. It is a schematic plan view of the principal part of the twisting and disposing of the auxiliary selvage used. In FIG. 1, a material 1 is obtained by winding a throw-away ear 2 around a bobbin 3 made of a metal in a laminated winding to form a fiber layer having a large number of continuous holes. As shown in FIG. 2, the waste selvage 2 has several wefts 2A in which wefts 2B are textured, which are twisted as shown in FIG. 3, and the wefts 2B project fluffy on the surface. This material 1 can be manufactured at low cost, and has extremely excellent over-performance when used as a cartridge filter due to the sublimation of the throw-off ear 2 and the presence of the fluffy weft 2B.

In the above material 1, the warp yarn 2A and the weft yarn 2B that form the cut end 2 are preferably synthetic fibers such as polyester and nylon, which have excellent dimensional stability even when wet, and have a fineness of 30 denier to 100 denier used for ordinary woven fabrics. All multifilaments are applicable. The number of warp yarns 2A is usually 3 to 5, and the number of weft yarns 2B to be driven is determined by the woven structure and is usually 20 to 100 yarns / inch, but any of these can be applied. Furthermore, the number of twists of the throwing selvage 2 is determined by the weft tension at the time of weaving, and is usually twisted at a twist number of 20 to 70 times / inch. Any of these can be applied, but the higher the number of twists, the more sublime it becomes. In addition, it is preferable that the weft 2B protruding in a pile shape on the surface is prevented from coming off. Further, the twisted waste ear 2 itself is rich in elasticity due to twisting shrinkage, but it is contracted by further simple drying treatment or wet heat treatment to increase elasticity, which is more preferable as a material.

The perforated bobbin 3 is a hollow cylindrical bobbin having a large number of holes 4, may be made of synthetic resin such as polypropylene, and may have an outer diameter of 25 to 40 mm. Further, the winding density, the porosity, the traverse angle, the winding layer thickness, and the like when the throwing tab 2 is wound around the perforated bobbin 3 can be variously selected according to the grain size of the excessive object.

Effect of the Invention As described above, the material of the present invention has the efficiency of collecting foreign matter by winding the twisted auxiliary selvage of the auxiliary selvage yarn when weaving with the shuttleless loom around the bobbin with holes. It has excellent performance and excellent performance, can be manufactured at extremely low cost, and has a particular effect of contributing to the reuse of the waste ear that was conventionally industrial waste.
