Title:
METHOD FOR IMPROVING FASTNESS OF INTERLACING OF INTERLACING MULTIFILAMENT
Document Type and Number:
WIPO Patent Application WO/2023/124514
Kind Code:
A1
Abstract:
A method for improving fastness of interlacing of interlacing multifilament using a DTY spinning process. The multifilament (1) which is not subjected to interlacing is adjusted by a tensioner (2) for a pre-tension, is held by a feeding roller (3) and a feeding leather roller (4), is fed into and passes through a yarn channel (6) of a nozzle (5), is held and led out by a yarn guiding roller (8) and a yarn guiding leather roller (9), and is wound by a winding roller (10), so as to obtain the interlacing multifilament; and a connecting line between a holding point between the feeding roller (3) and the feeding leather roller (4) and a holding point between the yarn guiding roller (8) and a yarn guiding leather roller (9) coincides with a central axis of the yarn channel (6), the feeding roller (3) and the yarn guiding roller (8) has an equal linear speed, and when the multifilament passes through the yarn channel (6) of the nozzle (5), a nozzle port I (11) and a nozzle port II (12) respectively intermittently inject a compressed airflow into a yarn channel A and a yarn channel B, and the pressure intensity of the compressed airflow injected into the yarn channel (6) by the nozzle port I (11) is greater than the pressure intensity of the compressed airflow injected into the yarn channel (6) by the nozzle port II (12). The multifilament after interlacing is not prone to loosening during weaving, which can achieve weaving without twisting and starching, thereby shortening a weaving process.
