A production method for false twisting and texturing of yarn and a detection method for tail joints in the process of false twisting and texturing of yarn

Abstract

The invention discloses a production method for false twisting and texturing of yarn and a detection method for over-tail joints in the process of false twisting and texturing of yarn. The elastic process, and: (1) Make the yarn of multiple yarn coils connected head to tail in sequence pass through the detection channel and then perform the false twist and elastic process, and the detection channel passes through a yarn coil that has finished the yarn Switch to the position change information of the last yarn roll connected in sequence from head to tail to collect, and each position change information collected identifies a tail joint; (2) When a position change information is collected, there will be an over end joint; After the false twisting and texturing of the tail joint, the rolled coil is switched off, and a new false twisting and texturing is performed again, and so on; Automatic detection of over-end connector information avoids misrecording or omissions that are prone to occur due to excessive reliance on manual intervention, and improves efficiency and reduces costs.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a production method for false twisting and elasticizing of yarns and a method for detecting over-tail joints in the process of false-twisting and elasticizing of yarns. Background technique [0002] "Yarn false-twisting and elasticizing" refers to a yarn with certain characteristic properties obtained by false-twisting and elasticizing a certain yarn, including but not limited to polyester yarns that are relatively common in the textile field, such as POY ( Pre-oriented yarn (high-speed spinning)) and DTY (stretch textured yarn, usually called polyester low elastic yarn), DTY uses polyester pre-oriented yarn (referred to as POY) as raw yarn and then through stretching, false twist texturing processing Post-production, in this process, since POY exists in rolls, there must be tails and heads of rolls in the process of making it into DTY. There are two production methods, one is...

[0002] "Yarn false-twisted texturing" refers to a yarn with certain characteristic properties after false-twisted texturing, including but not limited to the more common polyester yarns in the textile field, such as the POY ( Pre-oriented yarn (high-speed spinning)) and DTY (drawn textured yarn, usually called polyester low-elastic yarn), DTY uses polyester pre-oriented yarn (referred to as POY) as the original yarn and then processed through stretching and false twist deformation. Afterwards, in this process, since POY exists in rolls, there must be a tail and a head in the process of making it into DTY. There are two production methods, one is when After one roll of POY yarn is produced, another roll is replaced. This method requires frequent manual lifting of the new yarn roll, which is inefficient and overly dependent on manual work. It is easy to make mistakes or forget to lift the roll, and there are many waste yarns. Another way is: in order to improve production efficiency and other purposes, the head and tail between multiple POY rolls are generally connected in sequence in production. Some of the DTY rolls will contain over-end joints (for example, it is common in the prior art, usually a 15 kg POY is false twisted and bombarded to make three 5 kg DTYs, and the last DTY usually exists Over-end joints), in order to improve the grade of DTY silk rolls, at present, the information of such over-end joints is usually recorded manually, and then cleared in the later stage, but this method also relies too much on manual intervention, which is prone to misrecording Phenomena or omissions, and the efficiency is low, the labor cost is high, and there may be more waste silk, and the cost of raw materials is not easy to reduce
