Abstract

The invention relates to melt-blown cloth and a preparing system and a preparing process thereof. The melt-blown cloth comprises the following components including, by weight, 75 parts of polypropylene resin, 35 parts of polyethylene terephthalate, 22 parts of titanium dioxide, 3 parts of a dispersing agent, 5 parts of a stabilizing agent and 3 parts of an auxiliary agent. The process comprises the following steps of 1, putting a raw material solution into a discharging device, and pressing the solution into a spray head assembly after the discharging device is started; 2, under the drafting action of two high-temperature airflow generators, forming superfine fibers by using the raw material solution sprayed out of the spray head assembly; 3, conducting bonding on the sprayed superfine fibers under the action of self-bonding, and forming the melt-blown cloth on a receiving device through cooling of two high-temperature airflow generators; 4, enabling the running receiving device to drive the melt-blown cloth to be conveyed leftwards and wound on a cloth winding roller; and 5, cutting the two ends of the melt-blown cloth by two edge cutting devices.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production, more specifically a melt-blown cloth and its preparation system and preparation process. Background technique [0002] The patent number is CN201410524317.5, a method for preparing fluffy melt-blown cloth, the invention relates to a method for preparing fluffy melt-blown cloth; raw materials are heated, melted and extruded through a screw extruder, filtered through a filter, and then transported through a pipeline The melt is measured by the metering pump, and then sent to the die head, and fine fibers are formed under the drafting action of high-speed hot air. Under the action of negative pressure, the fiber is laid on the web forming table to form a non-woven fabric; it solves the problems of hard hand feeling of the cloth surface, poor fluffy performance of the fiber, and thin cloth surface thickness; it is fluffy, tough and soft to the touch. However, this device cannot c...
