Whether it is chemical fiber, or special fiber, such as glass fiber and carbon fiber, it is necessary to measure the oil content of the fiber surface.The oil content not only affects the quality of fiber, but also affects the economic benefit of production cost.Time-domain NMR technology can quickly determine the oil content in fiber, which is very important for product quality control.

The solid content of fiber soakage is the key index that affects the oiling rate of fiber, so it is necessary to carry out regular detection to ensure the normal production of fiber.Traditional solid content detection methods need to dry the emulsion for as long as 2 hours, which makes it difficult to quickly detect abnormal changes in the production process.However, NMR time domain technology only needs one or two minutes to accurately determine the solid content of the emulsion.
