Abstract

The invention relates to a melt-blown die head for nanofiber preparation. The melt-blown die head comprises a die head main body, a spinneret plate and an air plate, and the spinneret plate and the air plate are detachably mounted in the die head main body; a spinneret hole is formed in the spinneret plate, multiple slots are formed between the spinneret plate and the air plate, multiple air flowing channels are further formed in the die head main body, and the air flowing channels are communicated with the slots; air tube connection end sockets are arranged on the outer wall of the die head main body and are communicated with air flow collection cavities through air conveying pipes, interval steady flow parts are fixedly connected with one end face of the spinneret hole of the spinneret plate, a pipe connection device is fixedly connected with the other end face of the spinneret hole, and the spinneret hole is connected with a material outlet of a screw extruder through the pipe connection device. The melt-blown die head for nanofiber preparation has the advantages of being simple in structure, easy to manufacture, practical and efficient.

Description

technical field [0001] The patent of the present invention relates to the field of melt-blown nonwovens, especially a melt-blown die for nanofiber preparation. Background technique [0002] Melt-blown nonwoven technology began in the 1950s. It is a one-step technology that directly prepares ultrafine fibers and their fiber webs using polymer slices as raw materials. [0003] Earlier research, patent literature and related patent literature on the melt-blown nonwoven process, technology and die device include: [0004] 1. Naval Research Laboratory Report 4364 "Manufacture of Superfine Organic Fibers," Apr.15, 1954. [0005] 2. Wente Van A., Industrial and Engineering Chemistry, 48, No. 8 (1956, pp1342-1346). [0006] 3. Naval Research Laboratory Report 4364 "Formation of Superfine, Thermoplastic Fibers," Feb.11, 1959. [0007] 4. US patent document USP3379811. [0008] 5. US patent document USP3437725. [0009] 6.
