Problems solved by technology

[0002] The traditional filter felt is made of needle-punched twisted short silk base cloth, which has poor adaptability and is easy to deform. After use, the hole distance and density will change to varying degrees, which affects the use effect and has a short service life.

Embodiment Construction

[0022] 1. Textile preparation: multi-strand 1000D polypropylene non-twisted filament raw materials are treated without pollution and breakage.

[0023] 2. Warp yarn preparation: warp yarn winding shaft, 72 yarns per 10cm.

[0024] 3. Weft yarn preparation: reverse the weft yarn to make the weft pipe even, so as to prevent the multi-strand untwisted yarn from fluffing.

[0025] 4. Upper machine textile: upper machine textile untwisted filament base fabric, steel buckle is specially made, upper warp shaft, threading buckle upper warp and weft 1000×1000D.

[0026] 5. The untwisted filament base fabric is shaped: the base fabric is shaped according to the designed width and warp and weft density, the setting temperature is 300°C, the setting heat control distance is 5cm, and the speed is 300m / h.

[0027] 6. Measure the weight of composite filter felt raw materials and base cloth: measure the weight of raw materials and base cloth, the base cloth is in the middle, with polyester l...

Abstract

The invention relates to a technique for filament untwisted base fabric compositing filter mat, which is a filter mat technique in high-density and high-strength filter materials used in industry and environmental protection. Traditional filter mat is produced by needling twisted staple base fabric and is easy to deform, and hole distance and density thereof are changed after use and use period is short. The technique of the invention comprises spinning preparation, weft yarn preparation, spinning on machines, base fabric forming, measuring the weight of compositing filter mat raw material and base fabric, extruding and thermoforming, cutting, punching and edge sealing. The filament untwisted base fabric compositing filter mat produced by the technique has smooth surface, fast filtering speed, no deformation after washing for a plurality of times, long use period, guarantee of effective filtering area and unchanged hole distance, is acid and alkaline resistant and easy for disassembly and assembly and cleaning, has little water consumption for cleaning and maintenance and low labor intensity, achieves the optimal effects of yield, output, quality and emission reduction, and is energy-saving, emission-reducing and cost-saving. Products produced by the technique can be applied to the high-tech fields of petroleum, optical fiber, concrete, metallurgy, soybean fiber, bioengineering, textile printing, environmental protection, etc.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to a high-density, high-strength, and long-life filament untwisted base cloth composite filter felt technology used in industry and environmental protection. Background technique [0002] The traditional filter felt is made of needle-punched twisted short silk base cloth, which has poor adaptability and is easy to deform. After use, the hole distance and density will change to varying degrees, affecting the use effect, and the service life is short. Contents of the invention [0003] The object of the present invention is to provide a filament untwisted base fabric composite filter felt process that prolongs the product life cycle, has high strength, good stretchability, high density, and is not easily deformed, and is suitable for use in various industries and environmental protection. [0004] The filament untwisted base cloth composite filter felt process of the presen...
