[0002] The paper machine blanket is a very commonly used equipment in the paper industry. It is installed in the paper making equipment, and its diameter plays a vital role in the forming and surface quality of the paper. It is used in a huge amount, but in actual use, the current The traditional structure used in paper machine net blankets, although it can meet the needs of use, but the structural strength, wear resistance and surface quality of the net blankets are relatively poor. As a result, the quality stability of the prepared paper products is seriously insufficient, and the production cost is relatively high, and the production efficiency is low. Therefore, in response to this problem, it is urgent to develop a new paper machine clothing and its related production process to meet practical needs

Embodiment 1
[0026] Such as figure 2 Shown, a kind of production technology of paper machine net blanket comprises:
[0027] The first step is connection, first connect the carrier layer and the transition layer through connecting lines,
[0028] The second step is to heat up the welding. The connected carrier layer and the transition layer are heated to 80°C and kept warm. While raising the temperature of the carrier layer, the thermoplastic polymer of the porous composite polymer layer is heated to a molten state. It is fully mixed with hard non-metallic spherical particles and evenly sprayed onto the transition layer connected by one of the carrier layers;
[0029] The third step is to connect and set the shape, cover the rest of the carrier on the porous composite polymer layer, and then evenly spray a coagulant on the carrier layer connected to the porous composite polymer layer, and the temperature of the coagulant is 10 ° C, and When the coagulant is sprayed, the surface tension ...

The present invention discloses a papermaking machine felt comprising at least two carrier layers, a porous composite macromolecular polymeric layer covering at least one surface of the carrier layers, a transitional layer for connecting the carrier layers and the porous composite macromolecular polymeric layer, and a woven fabric layer applied on the outer sides of the carrier layers and the porous composite macromolecular polymeric layer, wherein the carrier layers are connected by the porous composite macromolecular polymeric layer. The production process of the invention is simple and easy to control, the degree of standardization of the production process is high, and the prepared felt has the good properties of carrying capacity, structural stability, abrasion resistance, high temperature resistance and chemical resistance, so that on the one hand, product quality and performance of the papermaking machine felt are effectively improved; on the other hand, production process difficulty and production and use cost of the papermaking machine felt are effectively reduced.
