The blended air-jet spun yarn of linen-like polyester fiber and ordinary polyester fiber is exploited in NO.

In this article,the effects imparted by the quality of the semi-product on the strength and evenness of air-jet spun yarns were simply analyzed,and those imparted by the technology of air-jetspinning machine,such as nozzle pressures、drawing ratios、collector breaths etc,were emphasized.

Position optimization of the two nozzles on the the double nozzles air-jet spinning machine;

The Influence of the Installation Position of the Air-jet Spinning Nozzel on the Yarn Strength;

The first nozzle structural parameters of air-jet spinning machine mainly include jet orifice obliquity,nozzle inside diameter,jet orifice number.

Open-end jet spinning is a new spinning method, which works in such a way that a high-speed air current forms the open end with the aid of roller drafting, while a high-speed rotating air current inserts twist to the sliver.

As to the current situation of high cost and limited market in China for the special top roller on the hi-speed air-jet frames MJS802H and MJS802RH,introduction is made to the development and application effect of the special top roller TCP76 regarding dynamic performance,strength,elasticity,pressure deformation and rigidity given anti-abrasion of the top roller.

Unidirectional glass/polypropylene composites was fabricated in a hot press by using air jet commingled yarn of 50∶50 wt% glass fibers/polypropylene filaments.
