    Abstract: A continuous process for the wet chemical treatment of fibers employs one or more squeezing/opening operations post chemical treatment to provide even chemical distribution on the fibers being processed. For squeezing the fiber batt impregnated with chemicals, one or more sets of squeeze rollers which include at least one roller with grooves are used to remove the liquid chemicals from the fiber batt efficiently. The squeezing operation can be coupled with the ability to collect and recycle chemicals for reuse in the chemical treatment process. The continuous process for the chemical treatment of fibers may employ the use of a blending box for the dried chemical-treated fibers in order to compensate for any uneven chemical distribution on fibers occurred during the chemical treatment process.

The copolymers are usually used here in the form of aqueous dispersions. The fiber materials are in particular fabrics, for example made of polyolefin. Treatment with the copolymers imparts to them oil- and water-repellent properties and also repellent properties toward low molecular weight alcohols.

  • Publication number: 20130280513
    Abstract: A hygroscopic fiber is a fiber including polyamide 56 resin, and having a ?MR of at least 3.0%. A method for manufacturing the fiber is by a direct spin draw method in which: a polyamide 56 fiber discharged through a spinneret is cooled and solidified by cooling air; a spinning oil is deposited thereon and the fiber is stretched; and the fiber is taken up. The manufacturing method satisfies (1) the spinneret discharge line rate is between 14 m/min and 30 m/mm; and (2) the product of the take up velocity and the draw ratio is between 3900 and 4500.
