  Spin Finish Measurement

  November 6, 2022 Applications / Articles

  Spin finish is an important quality control parameter in textile, it's directly determines whether the fiber can meet the requirements of use. Uneven spin finish is a common problem in chemical fiber production. Fibers with low oil content are prone to static electricity, while fibers with high oil content are prone to entanglement, both of which will seriously affect the n ...

  Low field NMR Study on Seed Germination Process

  October 18, 2022 Applications / Articles / Food & Agriculture

  Low field NMR Study on Seed Germination Process Seed Germination Process The seed germination process is divided into 4 steps: imbibition, water and enzyme activation, seed embryos break through the seed coat, and grow into seedlings. Imbibition: soak the seeds in water or the seeds in moist soil, the hydrophilic substances in the seeds will absorb water molecules, w ...
