Problems solved by technology

[0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is formed by orienting or randomly arranging short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. In the existing production process, the raw materials need to be heated and stirred, but when heated and stirred, they are heated from the bottom, which leads to uneven heating and reduces the heating effect; on the other hand, because the stirring will not bottom, so when stirring the molten mixture, the reduction effect will be reduced

Abstract

The invention discloses a processing technology of a melt-blown non-woven fabric. The processing technology comprises the following steps: a, crushing, specifically, crushing a polypropylene raw material; b, stirring, specifically, putting the raw materials into a stirrer, adding a thermal toughening agent, and stirring; c, carrying out spinning treatment, specifically, carrying out spinning treatment on a molten mixture; and d, processing, specifically, processing fiber yarns prepared in the step c to obtain a melt-blown fiber layer, wherein the stirrer in the step b comprises a main body, a heating device, a motor, a stirring roller, a stirring device, a feeding hole and a discharging hole. The raw materials are uniformly heated through the heating device, and the raw materials are prevented from sticking into the main body during melting to affect the stirring effect; the uniformity of the bottom of the mixture is improved through a stirring plate, and the stirring effect is further improved, so that the product quality is improved; and the stirring device realizes heating and mixing of the thermal toughening agent, so that the thermal toughening agent is directly mixed in the mixture in the stirring process, the stirring effect is improved, and the product quality is further improved.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a processing technology of melt-blown non-woven fabrics. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is formed by orienting or randomly arranging short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. In the existing production process, the raw materials need to be heated and stirred, but when heated and stirred, they are heated from the bottom, which leads to uneven heating and reduces the heating effect; on the other hand, because the stirring will not The bottom of the tank, so the reduction effect will be reduced when the molten mixture is stirred. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a process for improving the uniform stirri...
