Then the properties of the slurry, sizing and the raw yarn, such as the infrared spectrum, the melting point and water-solubility were surveyed, and the results were compared. The results indicated that the slurry can develop the physical and mechanical properties and be suitable for sizing to...
The value of flow time was an average of three values with a standard deviation within ±0.2 s. The flow time of H2SO4 and each of the polymer solutions were used to calculate the relative and specific viscosities. Single point intrinsic viscosities were then calculated using the Solomon and...
