 Yarn is a basic material in the textile industry and is widely used in various types of fabrics. For this reason, the quality of the yarn is the key to determining the textile quality in the later stage of textile processing. For example, in the case of polyester synthetic fiber spinning, a yarn tension checker is generally attached to a false twisting machine provided at the later stage of the process, and if there is a quality change due to a mechanical or human error in the false twisting process, an immediate Anomalies are detected based on the check data to reduce material consumption. However, there is no countermeasure against the above-mentioned variation of the raw fiber, and this is a problem that is currently awaited to be solved in the textile industry.

[0003] In the current high-speed spinning, any of fully drawn yarn (FDY), semi-drawn yarn (POY) and forward-oriented yarn (FOY) is used in the whole spinning process or in the subsequent high-speed false twisting process. However, when the yarn was pulled at high speed, the fiber was ruptured or fuzzed due to friction, and a phenomenon of being charged with static electricity occurred, and it was easy to cause deformation during processing. The only way to control this phenomenon is to add oil during the spinning process.However, the oil must be added in an appropriate amount, and if it is too large or too small, it will directly affect the quality of the yarn. Was.

Further, the uniformity of the crystal of the chemically reactive molecule of the spinning material has a certain correspondence with the tension of the yarn, and the molecular crystallinity has a certain value in all of the strength, elongation and elasticity of the yarn. Has an impact. In the current spinning process, samples are checked on the surface of the product. However, it consumes time and effort, and a 1 / 1,000,000 sample is treated as representative of the overall quality, resulting in increased product consumption and manufacturing costs. Was expensive.
