Problems solved by technology

[0003] However, nylon materials are greatly affected by seasonal climate or environmental temperature and humidity. Especially in the rainy season in the south, the relative humidity in the air is relatively high, and can even reach saturation. After the nylon filter cloth absorbs moisture, its horizontal and vertical Elongation and the elongation rate will increase with the increase of humidity. At the same time, the filter cloth will feel hard and the surface will wrinkle. The unstable size of the nylon filter cloth will make the filter cloth products wrinkle, the filter cloth filter plate will be inaccurate, and the production process will be difficult. A series of problems such as bag dislocation seriously affect the service life of filter cloth

Embodiment 1

[0027] Example 1: Warp nylon monofilaments with a diameter of 0.225 mm to ensure uniform warp tension, and use five three-flying weft surfaces to strengthen the satin weave, with a warp density of 520 threads / 10cm and a weft density of 157 threads / 10cm. , draw the reed, and weave on the machine. The woven nylon filter cloth is calendered with a calender. The calendering temperature is 165°C, the speed is 7m / min, and the pressure is 7MPa. Put the calendered nylon filter cloth into Soak in water for 6 hours to obtain a pre-soaked nylon filter cloth. Take out the pre-impregnated nylon filter cloth, place it in a setting machine for high-temperature setting, the setting temperature is 148°C, the speed is 6m / min, and then it is dried;

Embodiment 2

[0028] Example 2: Warp the nylon monofilament with a diameter of 0.235mm to ensure uniform warp tension, and use five three-flying weft surfaces to strengthen the satin weave, with a warp density of 520 threads / 10cm and a weft density of 142 threads / 10cm. , draw the reed, and weave on the machine. The woven nylon filter cloth is calendered with a calender. The calendering temperature is 160°C, the speed is 6m / min, and the pressure is 8MPa. Put the calendered nylon filter cloth into Soak in water for 8 hours to obtain a pre-soaked nylon filter cloth. Take out the pre-impregnated nylon filter cloth, place it in a setting machine for high-temperature setting, the setting temperature is 145°C, the speed is 7m / min, and then it is dried.

Embodiment 3

[0029] Example 3: Warp nylon monofilaments with a diameter of 0.235 mm to ensure uniform warp tension, and use five three-flying weft surfaces to strengthen the satin weave, with a warp density of 567 threads / 10cm and a weft density of 161 threads / 10cm. , drawing reed, weaving on the machine, and the woven nylon filter cloth is calendered by a calender. The calendering temperature is 163°C, the speed is 7.5m / min, and the pressure is 7.5MPa. The calendered nylon filter cloth Soak in water for 8 hours to obtain a pre-soaked nylon filter cloth. Take out the pre-impregnated nylon filter cloth, place it in a setting machine for high-temperature setting, the setting temperature is 148°C, the speed is 6m / min, and then it is dried.

Abstract

The invention provides a chinlon monofilament filter cloth with a stable size and a production method thereof. The production method of the chinlon monofilament filter cloth with the stable size comprises the following steps: S1, taking chinlon monofilaments, then warping the chinlon monofilaments to ensure that the tension of warp yarn is uniform, then sequentially adopting satin weave, carrying out drafting and reed drawing, and weaving on a machine. According to the chinlon monofilament filter cloth with the stable size and the production method thereof, internal stress generated in a weaving process is reduced, the yarn is pressed into flat shapes from elliptical shapes, interwoven pores among the yarn and gaps among fibers are reduced, the surface of the filter cloth is flat and compact, a proper amount of water can play a role similar to a plasticizer, so that the chinlon fibers are slightly plasticized, therefore, the hydrogen bonding force on the surfaces of the chinlon fibers is weakened, the strength is high, the wear resistance is good, and the service life is long. The filter cloth has the advantages of compact pores, high filtering efficiency, small blockage, easiness in material stripping, difficulty in material leakage and the like, and is suitable for different high-temperature and strong-alkalinity working conditions such as coal washing, mines and sewage treatment.

Description

technical field [0001] The invention relates to the field of nylon monofilament filter cloth, in particular to a size-stable nylon monofilament filter cloth and a production method thereof. Background technique [0002] With the improvement of people's living standards, the country pays more and more attention to the requirements of environmental protection, the entire filtration market is developing rapidly, and the application of fiber filter materials in pollution control and environmental governance is becoming more and more extensive. The filter cloth material is the "heart" of the filtration and separation equipment and an important part that determines the separation effect. Filter cloths made of polyester, polypropylene, nylon, vinylon, and cotton are widely used in pharmaceutical, chemical, dye, steel, construction, sewage, chemical, ceramics, cement, coal washing, mining and other industries. Among them, nylon filter cloth is widely used in coal washing, mining an...
