Problems solved by technology

At present, there are melt-blown non-woven fabrics containing essential oil fragrances on the market, but essential oils are extremely volatile, resulting in too short fragrance retention time, which cannot achieve the effect of improving the odor of masks for a long time, so a melt-blown non-woven fabric with long-lasting fragrance retention is needed non-woven fabric

Embodiment 1

[0022] The first step is to melt the raw material; polypropylene pellets with a melt index of 1500g / 10min are used as the raw material.

[0023] Use a screw extruder to mix the raw materials evenly and melt them into a polypropylene melt; the screw extruder has 6 zones, the temperature of the first zone is 183°C, the temperature of the second zone is 195°C, the temperature of the third zone is 215°C, and the temperature of the fourth zone is 215°C. The temperature in the zone is 230°C, the temperature in the fifth zone is 220°C, and the temperature in the sixth zone is 220°C.

[0024] The second step is to spin the polypropylene melt under high-pressure hot air to form a polypropylene melt-blown non-woven material; the high-pressure hot air has a pressure of 0.08 MPa and a temperature of 210°C.

[0025] The fifth step is to use an air-blown spinning machine to evenly spray the mint-flavored natural essence on the polypropylene melt-blown non-woven fabric material, and dry the ...

[0028] The first step is to melt the raw material; polypropylene pellets with a melt index of 1400g / 10min are used as the raw material.

[0029] Use a screw extruder to mix the raw materials evenly and melt them into a polypropylene melt; the temperature in the first zone is 182°C, the temperature in the second zone is 194°C, the temperature in the third zone is 214°C, the temperature in the fourth zone is 228°C, and the temperature in the fifth zone is 218°C °C, the temperature in the sixth zone is 219 °C.

[0030] The second step is to spin the polypropylene melt under high-pressure hot air to form a polypropylene melt-blown non-woven material; the high-pressure hot air has a pressure of 0.1 MPa and a temperature of 220°C.

[0031] The fifth step is to use an air-blown spinning machine to evenly spray the rose-flavored natural essence on the polypropylene melt-blown non-woven fabric material, and dry the material with a hot air flow to obtain a finished product. The paramet...

Abstract

The invention relates to a production process of a melt-blown non-woven fabric with multiple fragrances. The production process comprises the following specific steps: by taking polypropylene particles with the melt index of 1000-1500g / 10min as raw material, uniformly mixing the raw material by using a screw extruder and melting the raw material into polypropylene melt; spinning the polypropylenemelt in high-pressure hot air to form a polypropylene melt-blown non-woven fabric material; uniformly spraying natural essences with different fragrances on the polypropylene melt-blown non-woven fabric material by using an air-jet spinning machine, and drying by using hot air to form finished products. The melt-blown non-woven fabric can be used for manufacturing masks, the essence is sprayed tothe non-woven fabric through an air-jet spinning machine, filtering efficiency of the masks is not affected, and the melt-blown non-woven fabric is harmless to human bodies, simple in structure, easyto use, high in breathability and good in dust-proof effect and has the effects of being fragrant, preventing vomiting, effectively relaxing bodies and mind, relieving pressure and fatigue and the like. The fragrance of the melt-blown non-woven fabric can be preserved for a long time, and can be preserved for more than half a year.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a production process of a melt-blown non-woven fabric with various fragrance types. 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 Corpo...
