Identifying the cause of destruction of textile linear structures

The article presents investigations into the mechanism of continuity loss of textile linear products. A method and tools for implementing it have been developed with the aim of investigating loose textile products, and determining the causes of their destruction. Special emphasis is placed on the usability of the procedure we accepted for investigating the resistance of the product's structure to the action of an aerodynamic force which occurs during the transport of weft with a weak structure. Two mechanisms of yarn breakage, especially that of loose wefts, have been differentiated. The first consists in breaking fibres which form the yarn, and the second in mutual slippage of fibres. Both mechanisms can be determined by analysing the force-elongation curves over yarn stretching in both static and dynamic conditions. The influence of an air stream acting longitudinally to the yarn, its velocity and time of action were also determined, with the aim of recognising the conditions of pneumatic weft transport.
