Abstract
An apparatus and method for modifying an aspect of an exterior polymer material or polymer type material of a linear substrate with a fluid. The apparatus include a variable exposure gap within which the linear substrate is exposed to the fluid. The width of the exposure gap is varied with the speed of the linear substrate traversing the exposure gap to maintain a constant exposure time of the linear substrate with the modifying fluid.
Claims15
A method for modifying an aspect of a linear substrate within a device filled with a modifying fluid, the method comprising:
- providing the device filled with the modifying fluid comprising additives;
- receiving the linear substrate at a feed speed;
- traversing the linear substrate through the device at a given speed to infuse the additives to the linear substrate, wherein when traversing through the device, the linear substrate is in a fluid communication with the modifying fluid, wherein traversing the linear substrate through the device further comprises increasing or decreasing the feed speed of the linear substrate;
- defining an exposure length of the linear substrate as a length of the linear substrate that is in the fluid communication with the modifying fluid in the device;
- and
- adjusting the exposure length of the linear substrate based on the feed speed and a predetermined exposure time, wherein adjusting the exposure length of the linear substrate comprises further adjusting the exposure length of the linear substrate based on an acceleration of the linear substrate from the feed speed due to the increase or the decrease of the feed speed and a measurement of infusion level of additives from the modifying fluid in the linear substrate exiting the exposure length, and wherein adjusting the exposure length of the linear substrate based on the measurement of infusion level of additives from the modifying fluid in the linear substrate exiting the exposure length comprises:
- increasing the exposure length when the measured infusion level of additive is below a desired infusion level of additive, and
- decreasing the exposure length when the measured infusion level of additive is greater than the desired infusion level.
A method for modifying an aspect of a linear substrate extended through a device filled with a modifying fluid, the method comprising:
- providing a device filled with a modifying fluid comprising additives;
- extending a linear substrate through the device;
- defining an exposure length of the linear substrate within the device, the exposure length comprising a length of the linear substrate that is in the fluid communication with the modifying fluid in the device;
- traversing the linear substrate in the device at a given speed to infuse the additives to the linear substrate, wherein traversing the linear substrate through the device further comprises increasing or decreasing the given speed of the linear substrate;
- adjusting the exposure length of the linear substrate based on an acceleration of the linear substrate from the given speed due to the increase or the decrease of the given speed and a measurement of infusion level of additives from the modifying fluid in the linear substrate exiting the exposure length, wherein adjusting the exposure length of the linear substrate based on the measurement of infusion level of additives from the modifying fluid in the linear substrate exiting the exposure length comprises:
- increasing the exposure length when the measured infusion level of additive is below a desired infusion level of additive, and
- decreasing the exposure length when the measured infusion level of additive is greater than the desired infusion level.
