Abstract

In general, the study showed that swelling index (water retention), a simple test commonly used in the industry, is as good a parameter as the nitrogen content, which is difficult to measure, for evaluating the level of wrinkle-free treatment. Wrinkle-free treatment can generally reduce the tear strength and the dynamic water absorption rate. The former is a property important to fabric durability and the latter is a property important to clothing comfort.

  1. (1)

    The swelling index (water retention) has a strong linear relationship with the total nitrogen content in the fabric. The higher nitrogen content, the lower the swelling index (water retention).

  2. (2)

    The fabric tear strength is highly correlated with the total nitrogen content or the swelling index (water retention). High nitrogen content or low swelling index (water retention), which may be resulted from the wrinkle-free treatment, causes low tear strength

  3. (3)

    High nitrogen content or low swelling index (water retention) reduces the water absorption rate of the fabric and increases the contact angle when the water drop is in initial contact of the fabric.
