Description
Technical Field
The invention relates to the technical field of melt-blown non-woven fabric equipment, in particular to a combined type special-shaped melt-blown spinning die head.
Background
Melt-blown nonwoven fabrics were produced by subjecting a melt of a high polymer extruded from an extruder to extreme drawing by high-speed hot air or other means (e.g., centrifugal force, electrostatic force, etc.) to form extremely fine short fibers, which are then agglomerated to a porous drum or a screen to form a web, which is then bonded to itself or consolidated by thermal bonding, and in the early 20 th century, 50 th generation, the american navy laboratories began to study the air jet spinning method in which nylon was melted and extruded through a special spinneret while the melt of the high polymer was finely drawn by high-speed hot air to form ultrafine nylon nonwoven fabrics having a fiber diameter of 5 μm or less, and thus, the melt-blown nonwoven fabrics were the earliest ultrafine fibers and the finest ultrafine fibers directly spun up to now, and almost simultaneously, the american company Inc (northern, d The fabric, which was patented in the united states, published a paper on the "jet-spun fiber" manufacturing process, and the product was used primarily as a filter material in the united states air force and in some special situations.
The development of the melt-blown non-woven fabric in China is relatively early, and related units begin research in the aspect as early as the 20 th century and the 50 th century. In 1960, the Beijing synthetic fiber laboratory works and the Beijing chemical research institute of chemical industry department cooperated, and the perchloroethylene superfine non-woven fabric is successfully researched by adopting the air jet → electrostatic spinning → roller web forming process. In recent years, many domestic units have made a lot of work in the aspects of melt-blown spinning theory research, key equipment processing, product application development and the like, and have made certain progress, and dozens of domestic production lines (batch type) are in existence. However, the processing technology of the large-width spinneret plate is not related, so that the application and development cannot be kept up with the standard, and the development speed is relatively slow. Whether the yield, the quality or the product specification has a certain distance compared with the foreign level. In order to accelerate the development of the melt-blown non-woven fabric, more than ten melt-blown production lines are introduced in China one after another, so that the non-woven fabric is melt-blown in China. The production capacity is greatly improved.
Nonwoven fabrics produced by the meltblowing process have fine fibers, a large specific surface area, small voids and a large porosity, and therefore, are excellent in filtration properties, shielding properties, heat insulation properties, and adsorption properties. In order to achieve the use purpose, the diameter of the fiber is at least less than 0.25mm, so the melt-blown fabric is widely applied to the fields of medical and civil masks, heat-insulating materials, medical and sanitary materials, sound-insulating materials and the like. The existing mechanical manufacturing industry is developed, but the manufacturing problem of the slender holes is difficult and heavy, one important factor influencing the quality of the melt-blown fabric is the length-diameter ratio of the nozzle holes, the larger the length-diameter ratio is, the better the quality of the melt-blown fabric is, and the length of the nozzle holes is at least more than 3mm when the good melt-blown fabric is required to be manufactured; another problem affecting the quality of meltblown fabric is the shape of the fibers forming the meltblown fabric, and in the existing meltblown fabric technology, the diameter and the cross section of the nozzle hole of the meltblown die head are all circular, so that the fiber surface area is reduced, the specific surface area of the meltblown fabric is reduced, and the manufactured meltblown fabric is low in adsorbability.
The traditional melt-blowing die head is mainly characterized in that slot type blowing is utilized to form a certain angle to be distributed on two sides of a spinneret orifice, the spinneret orifice is in a slender circle shape, the existing mechanical drilling technology has technical barriers for drilling of micro holes with a certain length, or only circular slender holes can be obtained by drilling, and the slender holes in other shapes cannot be obtained by drilling.
The invention 202010025102.4 discloses a special-shaped spinning nozzle structure, which comprises a middle block module and an edge block module, wherein the edge block module is arranged at the outer side of the whole body of the middle block module, an airflow channel is formed between the edge block module and the middle block module, special-shaped spinneret holes with different pore diameters are arranged on a spinneret nozzle, so that special-shaped fibers obtained by spinning have special geometric shapes, and the bulkiness, porosity and tensile strength of a non-woven fabric are improved by entanglement among the special-shaped fibers.
Since the core of the filter material, which may be a melt-blown nonwoven fabric, is the adsorptivity of the fibers, and the conditions determining the adsorptivity of the fibers include the thickness of the fibers and the specific surface area of the fibers, the finer the fibers, the larger the specific surface area of the shaped fibers, and thus the more effective the shaped fine fibers can be made. The prior art discloses the shape of the nozzle hole, but does not disclose the manufacturing method of the special-shaped shape, and the current machining and drilling technology has technical limitation on obtaining round elongated holes by using the drilling technology, the drilling of the special-shaped elongated holes is more extensive, the price of the small holes with larger length-diameter ratio is more expensive, one melt-spraying cloth nozzle needs hundreds or thousands of nozzle holes, the manufacturing cost is high, and no effective solution is provided for the special-shaped elongated holes.
