Problems solved by technology

[0005] The melt-blown cloth currently produced is mostly used for dust masks and industrial composites. It has high requirements for the tensile strength of the material, but the cloth surface feels hard, the fluffy performance of the fiber is poor, and the thickness of the cloth surface is thin, which cannot meet the industrial requirements. Wiping cloth requirements for fluffy softness and cloth thickness of melt blown cloth

Embodiment Construction

[0015] See figure 1 , select polypropylene pellets with a melt index of 1200-1800 to transport them to the hopper of the screw extruder, heat and melt them through the screw extruder 1, transport them to the die head 5 for spinning, and draw them into fine fibers in the high-speed hot air 6, After the cooling of the side blower 7, the fibers are laid and bonded into cloth with the assistance of the front overflow fan 9, the suction fan 10 and the rear overflow fan 11.

[0016] The temperature of the screw extruder 1 is 170-190°C in the first zone, 225-245°C in the second zone, 230-250°C in the third zone, 230-250°C in the fourth zone, and 230-250°C in the fifth zone. ℃, the temperature of zone 6 is 230-250℃, the temperature of filter 2 is 230-250℃, the temperature of pipeline 3 is 230-250℃, the temperature of die head 5 is 230-250℃, the temperature of side blower 7 is 11-13℃, cooling fan The output ratio is 45%-55%, the temperature of drafting hot air 6 is 230-250°C, the outp...

Abstract

The invention relates to a fluffy melt-blow cloth preparation method. The method comprises the following steps that raw material is heated and melt via a screw extruder and then extruded to be filtered via a filter; then the melt and filtered raw material is conveyed to a metering pump for melt measurement via a pipeline; the melt is sent to a die head and forms fine fibers due to a traction action of high-speed hot air; and the fibers are cooled via cross air blasting and are then lapped on a net forming bench to form a non-woven fabric due to a negative pressure action of a front overflow draught fan, a pumping draught fan and a back overflow draught fan. By the use of the fluffy melt-blow cloth preparation method, problems of hard cloth surface hand feeling and poor fluffy performance of the fibers as well as thin cloth surface can be solved; and the fluffy melt-blow cloth is fluffy, has great tenacity and soft hand feeling.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing fluffy melt-blown cloth. Background technique [0002] Meltblown technology originated in the 1950s. It is a technology developed by the U.S. Navy to collect radioactive particles in the upper atmosphere to manufacture air filters with ultra-fine filtration effects. In the 1970s, my country was established by Shanghai Textile Science The research institute started the research on melt-blown technology, and its results have been applied in practice. [0003] Exxon Corporation of the United States started research on meltblown technology in the 1960s and was the first to obtain patented technology. Since then, Reifenhauser in Germany and Accurate Products in the United States have adopted the patented technology transferred by Exxon. In addition, 3M Corporation in the United States, Freudenberg in Germany, Asahi Kasei Corporation in Japan, NKK C...
