Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0027] like Figure 1-4 , a method for processing melt-blown nonwoven fabrics containing short fibers, using a melt-blown nonwoven fabric processing device, the melt-blown nonwoven fabric processing device includes a screw extruder 1, a metering pump 2, a filter 3, a spray The silk mixing device 4 and the receiving device, the screw extruder 1, the metering pump 2, the filter 3 and the spinning mixing device 4 are sequentially connected through the melt conveying pipeline, and the mixed finished product 8 output by the spinning mixing device 4 is received by the receiving device; It is characterized in that: the spinner mixing device 4 includes a rectangular spinneret, a mixing chamber, an inner layer discharge device and a feed inlet, and the rectangular spinneret is divided into an outer edge area 11, a filament forming area 12 and a central A...

Abstract

The invention reLates to the technicaL fieLd of non-woven cLoth, in particuLar to a processing method for meLt-bLown non-woven cLoth containing short fibers. In the method, a processing device for themeLt-bLown non-woven cLoth is invoLved. The processing device comprises a screw extruder, a metering pump, a fiLter device, a spinneret mixing device and a receiving device, and mixed finished products output by the spinneret mixing device are received by the receiving device; the spinneret mixing device comprises a rectanguLar spinning nozzLe, a mixing cavity, an inner Layer discharging device and a feeding port; the inner Layer discharging device comprises an upper Layer discharging device body and a Lower Layer discharging device body. Compared with a traditionaL processing method for themeLt-bLown non-woven cLoth, the processing method for the meLt-bLown non-woven cLoth adopts the spinneret mixing device which is designed independentLy, can add the short fibers evenLy into meLt-bLownfibers and prevent the situation that the short fibers and others fLy around when added into the meLt-bLown fibers, and as a resuLt the environment of a workshop is poLLuted, and improves the utiLization efficiency of the short fibers and others.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a method for processing meltblown nonwoven fabrics containing short fibers. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics and non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. Among the many nonwovens, meltblown nonwovens are an important category. However, most of the traditional melt-blown nonwovens have a single composition, which restricts the application of melt-blown products. Today, technicians have begun to add short fibers or functional additives to melt-blown nonwovens to make the...
