Problems solved by technology

The smaller the center distance between the air drafter and the spinning device, the higher the density, the more uniform the fiber web, and the smaller the deviation rate of product thickness and square meter quality. The center distance between the air drafting device and the spinning device currently on the market All above 60mm, which is not conducive to the production of high-density non-woven fabrics

Embodiment Construction

[0006] Such as figure 1 As shown, the present invention is realized by adopting special-purpose airflow drafting device and spinning device, and airflow drafting device is that several tubular drafters 1 are fixed on the air guiding device 3, and the The center distance is between 35 and 55mm, and it communicates with the air hole 2 on the air guiding device. The device is composed of a spinning plate 6. The yarn receiving device 7 and the fixed shaft 5 are composed of the center distance between the spinning devices of 35-55 mm. The high-speed compressed air flows into the tubular drafter through the air guide device 3, and the primary fiber is in the tubular drafter. Under the action of high-speed compressed air, it is drawn to a fineness of 1.5-3 deniers, and the fibers are dispersed by a spinning device to form a fiber web.

Abstract

A tube-type drawing devillicating method comprises a special air flow drawing device and reciprocators. A plurality of tube-typed extension apparatus are arranged on an air flow guide device, the centre distances of the tube-typed extension apparatus are between 35 to 55mm, the tube-typed extension apparatus are communicated with the air holes which are arranged on the air flow guide device, separators are connected with the lower ends of tube-typed extension apparatus, reciprocators are separately connected with every separator, the reciprocators are composed of a swing board, a pick-up device and a fixed shaft, and the centre distances among the reciprocators are 35-55mm. The invention has the following advantages: a non-woven fabric which is made by the method has high density, the fiber web is uniform and the deviation ratio of the thickness and mass per square meter of the product is small.

Description

technical field [0001] The invention relates to a method for tubular drawing and splitting. Background technique [0002] In the production process of spunbonded nonwovens, the primary fibers are drawn under the action of high-speed compressed air in the air drafter (drawing tube), and the fibers are dispersed by a swinging disc to form a fiber web. The smaller the center distance between the air drafter and the spinning device, the higher the density, the more uniform the fiber web, and the smaller the deviation rate of product thickness and square meter quality. The center distance between the air drafting device and the spinning device currently on the market Both are above 60mm, which is not conducive to the production of high-density non-woven fabrics. Contents of the invention [0003] The present invention is achieved like this, and it adopts special-purpose air draft drafting device and spinning device. It is characterized in that the airflow drafting device is t...
