Embodiment Construction

[0009] The present invention is described in further detail below in conjunction with embodiment.

[0010] The invention discloses a production process of melt-blown non-woven fabric, comprising the following steps:

[0011] a) Extrude a mixture containing 50-80% PP granules, 5-15% PP powder, and the balance PP cooling masterbatch from the extruder, and control the temperature of the four zones of the extruder at 160-220°C, Then it is measured, and at the same time, it is filled with high-temperature and high-pressure air for spinning;

[0012] b) Combing the superfine fibers containing 20-50% PET fibers with a specification of 1.5D-6D, and then sending them together with the spun mixture into a drum receiving device for laying, so as to obtain a semi-finished product;

[0013] c) The upper and lower surfaces of the semi-finished product are glued and the composite specification is 10-5Cg / m 2 PP non-woven fabrics to obtain products.

Abstract

The invention discloses a production process for meltblown nonwovens. The production process comprises the following steps of: a) extruding a mixture of polypropylene (PP) particles, PP temperature reducing masterbatches and PP powder by using an extruder, controlling four-area temperature of the extruder to be 160-220 degrees, metering, and introducing high temperature high pressure air for spinning; b) carding superfine fibers containing 20 to 50 percent of poly(ethylene terephthalate) (PET) fibers, and feeding the fibers, together with the spun mixture, into a roller receiving device for laying a net to obtain a semi-finished product; and c) gluing the upper and lower surface of the semi-finished product and compounding PP non-woven fabrics in the specification of 10-50g / m<2> to obtain the product. The nonwovens produced by the process have fibers arranged in a V shape in the section direction, have high packing ratio, and have ideal sound absorption coefficient, puff extent and uniformity.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production process of a V-shaped melt blown nonwoven 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 the difficulty in the processing of meltblown nonwovens. [0003] The melt-blown non-woven fabrics in the prior art are mainly made of polyester mixed and then injected into high-temperature and high-pressure air melt-blown non-woven fabrics. From the cross-sectional direction of the obtained product, the fibers in the middle part are arranged in a disorderly and irregular shape, which is difficult to obtain. Ideal sound absorption, loft and uniformity with low filling. Contents of the invention [0004] The ...
