Problems solved by technology

However, in practical applications, it is often difficult to precisely control a wide temperature range (85-220°C) according to fibers of different properties; Satisfies the precise control of temperature, but because the heating wire is prone to open flames when heated, and the hot to red heating wire can easily cause a fire when the thermostat fails, so it is strongly avoided for the textile industry, and because of the need to use temperature control system, thus losing the effect of economical and cheap

Abstract

The invention discloses a wetting ironing method of a spinning fiber bundle and a PTC ironing device used by the wetting ironing method of the spinning fiber bundle, and belongs to the spinning technical field. The method includes the steps of enabling the spinning fiber bundle to pass through and be wetted by, under an advancing condition, a wetting device at a twisting triangular area portion in front of a front leather roller and a front roller of a twisting device which is arranged on and corresponds to a ring spinning frame, controlling the advancing speed of the spinning fiber bundle and water content of the wetted spinning fiber bundle, enabling the wetted spinning fiber bundle to enter the PTC ironing device, installed on the ring spinning frame along with the wetting device, to be ironed after getting out of the wetting device, controlling the ironing temperature of the PTC ironing device, and enabling the spinning fiber bundle which is ironed by the PTC ironing device to be wound on a spool through a winding device of the ring spinning frame to form a spindle. The amount of filoplume is reduced and therefore quality of yarn is improved; filoplume is prevented from being produced, a good and even evenness effect is obtained, the ignition point range of the yarn is avoided, and safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for moistening and ironing spinning fiber bundles, and also relates to a PTC ironing device used in the method. Background technique [0002] The PTC mentioned above refers to a positive temperature coefficient thermistor (usually referred to as a ceramic thermistor in the industry). As known in the textile industry, yarn hairiness not only affects the weaving efficiency of the loom, but also affects the finishing effect of the fabric, especially the final quality of the fabric, making it difficult to improve the grade of fabrics that are on the market. In addition, since the quality of yarn depends largely on the control of hairiness, whether yarn hairiness can be effectively eliminated in the spinning process is the prerequisite for ensuring yarn quality and the basis for improving fabric grades. [0003] Starting from the idea that the yarn is the first...
