Title:
COMPOSITE INTERLACED FILAMENT YARN AND INTERLACING METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/124513
Kind Code:
A1
Abstract:
A composite interlaced filament yarn and an interlacing method therefor. The interlaced filament yarn is a filament yarn subjected to an interlacing process, the filament yarn is a multiple-filament yarn, and the composite interlaced filament yarn is composed of a plurality of continuous repeat units in the longitudinal length; each repeat unit is composed of a splitting part I (2), an interlacing part I (3), a splitting part II (4) and an interlacing part II (5) which are connected in sequence; the interlacing intensity of the interlacing part I (3) is different from the interlacing intensity of the interlacing part II (5). The interlacing method comprises: sequentially passing a composite filament yarn that is not subjected to an interlacing process through a tensioner (6) to adjust the pre-tension of the composite filament yarn, and passing same through a yarn path (9) of a nozzle (7) and then winding same by means of a winding roller (8), so as to obtain the composite interlaced filament yarn. In the method, a nozzle hole I (10) and a nozzle hole II (11) are formed in the nozzle (7); when the composite filament yarn passes through the yarn path (9) of the nozzle (7), the nozzle hole I (10) and the nozzle hole II (11) intermittently inject a compressed airflow into the yarn path (9), wherein, per single injection, the time at which the nozzle hole I (10) and the nozzle hole II (11) inject the airflow is identical, the injection interval is identical, and the pressure intensity of injection of the compressed airflow into the yarn path (9) by the nozzle hole I (10) is greater than the pressure intensity of injection of the compressed airflow into the yarn path (9) by the nozzle hole II (11). By means of the interlacing method for a composite filament yarn, the application range of the interlacing technology is widened.
