Method of chemical treatment for fibers

摘要

Repeatable and reliable chemical treatment for loose fibers is achieved by spraying or immersing loose fibers in a chemical treatment bath, and continuously moving the soaked fibers through a continuous centrifuge. The continuous centrifuge controls the wet pickup of the chemical formulation on the fibers and assures a substantially even chemical distribution on the centrifuged fibers. The centrifuged fibers may be dried to fix the chemicals in the chemical formulation to the fibers and/or to remove water from the chemical formulation. Recycling of the chemical formulation from the continuous centrifuge allows for the process to be performed more economically and in a more environmentally friendly fashion.

主权项

1. A method for continuous chemical treatment of loose fibers, comprising the steps of:
applying a chemical formulation to loose fibers as said loose fibers continuously move through a chemical treatment bath; holding said loose fibers stationary while continuously conveying said fibers through said chemical treatment bath wherein said step of holding is performed by holding said loose fibers between two perforated conveyors; and then centrifuging with a continuous centrifuge said loose fibers with applied chemical formulation received from said chemical treatment bath to produce centrifuged loose fibers that have a substantially even chemical distribution.
