Abstract
The invention discloses a nonwoven fiber fabric, which comprises directly-formed V-shaped fibers arranged in the fabric. The fibers are composed of 65-75% melt-blown fibers and polyester short fibers to form a continuous, fluffy and elastic fabric structure without large clearances. The invention further discloses nonwoven fiber fabric production equipment, which comprises a receiver, a carding machine and a screw extruder, wherein the carding machine is arranged on the upper left of the receiver, and the screw extruder is arranged on the upper right of the receiver. A spinneret is connected to the bottom of the screw extruder, a lapping machine is arranged between the carding machine and the receiver, and a static generator which is positioned below the spinneret is arranged at the tail end of the lapping machine. The nonwoven fiber fabric with high filler is in V-shaped arrangement when viewed from a longitudinal vertical cross section and has ideal fluffiness and uniformity.
Description
technical field [0001] The present invention relates to fiber non-woven fabrics, in particular to a V-shaped melt-blown non-woven fabric when viewed along a longitudinal vertical section, and also relates to a production equipment for the V-shaped non-woven fabric. Background technique [0002] Nonwoven products can be seen everywhere in daily life, such as diapers, sanitary napkins, rags and filter products, etc. Many important properties of nonwoven products need to be performed by ultrafine fiber nets. The melting of ultrafine fiber nets Spray quality is a difficult point in the processing of non-woven fabrics. [0003] The non-woven fiber fabrics in the prior art are mainly made of polypropylene blended and injected with high-temperature and high-pressure air melt-blown. When viewed from the cross-sectional direction of the obtained product, the fibers in the middle part are arranged in a disorderly and irregular shape, and it is difficult to obtain ideal bulkiness. and...
