Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 2-5, the metal wire 4 is connected to the interior of the needled felt fiber 2, the outer side wall of the metal wire 4 is provided with a plurality of splicing ports 5, the splicing ports 5 are square, the metal wires 4 are vertically and staggeredly distributed in the needled felt fiber 2, a space is formed among the four vertically and staggeredly distributed metal wires 4, the space is square, and the outer side wall of the metal wire 4 is wound with polyester fiber.

The two metal wires 4 which are mutually vertical and staggered can be spliced together through the splicing ports 5 arranged on the metal wires 4, the side length of the square splicing ports 5 is equal to the diameter of the metal wires 4, and the depth of the square splicing ports 5 is equal to half of the diameter of the metal wires 4, so that after the two metal wires 4 are spliced together through the splicing ports 5, the two metal wires 4 above the splicing ports 5 can be kept horizontal, the abrupt situation can not be generated, and the needled felt is smoother.

The metal wire 4 can dredge the static that produces in the needle felt dust filtration operation process, prevents because of the gathering of needle felt surface static, adsorbs more dust, causes harmful effects to the filtration efficiency of needle felt to the dust, and the easy static of gathering of accumulational dust ignites and causes dangerous accident.

The shape of the space formed among the four metal wires 4 which are mutually perpendicular and staggered is square, the size of the square is the same as the diameter of the needled felt fiber 2, so that the metal wires 4 can limit the position of the needled felt fiber 2, the metal wires cannot move greatly under the action of external force, the positions of the needled felt fibers 2 after needling operation are compact, and the condition of dust leakage caused by large holes at individual parts due to needling cannot occur.

The interlaced metal wires 4 divide the gaps between the interlaced needled felt fibers 2 into four square spaces with the same size, so that the space through which dust can pass originally is reduced, the amount of dust which can be filtered by the needled felt fibers 2 is increased, and the dust filtering effect is enhanced.

The polyester fiber wound outside the metal wire 4 enables the metal wire 4 to be adhered to the outside of the metal wire 4 more easily when other coloring and smearing operations are carried out, so that the condition that the color of the produced needled felt is uneven and the appearance is not attractive and the sales is not influenced due to the fact that the metal wire 4 is difficult to color is prevented.

As shown in fig. 6, a waterproof breathable film 8 is connected to the upper surface of the needled felt fiber 2 close to the lower part of the wear-resistant layer 1, a hydrophobic coating 7 is connected to the upper surface of the needled felt fiber 2 close to the lower part of the waterproof breathable film 8, a plurality of sliding grooves 6 are formed in the upper surface of the hydrophobic coating 7, and the inner side walls of the sliding grooves 6 are connected with super absorbent resin.

The waterproof breathable film 8 can be used for blocking small water drops in air flow coming along with dust flow, so that the water drops are difficult to enter the position of the needled felt fiber 2 inside the needled felt, the needled felt fiber 2 is prevented from being wetted, dust is easy to adhere to the wetted needled felt fiber 2, the filter holes of the needled felt are blocked, and the dust filtration of the needled felt is influenced.

The water vapor in the air flow flowing along with the dust can reach the position of the hydrophobic coating 7 after passing through the waterproof breathable film 8, the water vapor is blocked at the position of the hydrophobic coating 7, more water vapor is gathered, the water vapor is condensed into small water drops on the surface of the hydrophobic coating 7 and is absorbed by the super absorbent resin in the chute 6, and the dust filtration cannot be adversely affected by the needled felt fibers 2.

The preparation steps of the super absorbent resin in the chute 6 are as follows:

adding starch into a reactor under the condition of introducing nitrogen, stirring, carrying out gelatinization operation at the temperature of 90 ℃, cooling to normal temperature after gelatinization, and adding 10 parts of acrylamide, methacrylic acid and acrylonitrile; 10; 9, carrying out graft copolymerization on the three in starch at the temperature of 30 ℃, adding water for decomposition at the temperature of 60 ℃, and drying and crushing a product to obtain the super absorbent resin.
