Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a continuous production process of PE breathable membrane composite fabrics, which solves the problem that the traditional production process is divided into two steps for production, in order to ensure that the water content of the breathable particles meets the production requirements during transshipment. Requirements, film encapsulation, drying and multi-step dehumidification steps are required for the breathable particles, which increases the production cost of PE (polyethylene) breathable membrane fabrics and increases the unit price of fabrics, which is not conducive to the production needs of enterprises

Abstract

The invention provides a continuous production process of PE breathable film composite fabric, and relates to the technical field of production of PE breathable film composite fabrics. The continuousproduction process of the PE breathable film composite fabric comprises used raw materials of, in percentage by weight, 44.5% - 54.5% of polyethylene, 45% - 55% of calcium carbonate and 0.5% of an additive. The continuous production process comprises the treatment processes of 1, putting the polyethylene, the calcium carbonate and the additive into a stirring device for fully and uniformly stirring; 2, then adding the mixed material into a mixing mill for heating, mixing and plasticizing, melting, impurity filtering and grain cutting; 3, carrying out drying and dehumidification treatment on the material subjected to grain cutting; and 4, heating and melting the dried and dehumidified granular material. By adopting the continuous production process, it can be guaranteed that the processingrhythm of the PE breathable composite fabric is compact, and redundant packaging treatment steps are reduced, so that the production cost of a product is reduced, and the production profit of an enterprise is increased.

Description

technical field [0001] The invention relates to the technical field of production of PE breathable film composite fabrics, in particular to a continuous production process of PE breathable film composite fabrics. Background technique [0002] The conventional production process of PE (polyethylene) breathable film is to heat and knead through a mixer to disperse calcium carbonate evenly in polyethylene, and then form breathable particles, which are then sent to the extruder, heated and plasticized, and passed through a T-shaped film. The die is extruded to form a film, and then the film is heated to an appropriate temperature, stretched and shaped properly, and then rolled to make a PE breathable film. [0003] The traditional production process is divided into two steps. In order to ensure that the water content of the air-permeable particles meets the production requirements during transshipment, it is necessary to carry out film packaging, drying and multi-step dehumidifi...
