Abstract:
Apparatus and process for reclaiming textile fiber waste utilizes an inner perforated duct and an outer continuous duct for removing air-borne fibers from air handling systems of equipment such as cotton carding machinery. A pressure differential switch monitors the operation and when a selected pressure differential occurs, the perforated duct is purged and the collected fibers in the form of a web are drawn through a conduit and returned for further processing.
Abstract:
The invention relates to bleached cotton fibers and to absorbing materials for disposable articles. Its object is a process for shortening bleached cotton fibers consisting in(a) moving a fiber pad (1) between a trough-plate (2) and a feed roller (5) exerting a pressure between 0.3 and 0.6 MPa on the fiber pad,(b) pulling the fiber pad (1) beyond the trough-plate (2) bevelled at (9) so as to cut the long fibers constituting the fiber pad,(c) reconstituting the sheet.This process makes it possible to obtain fibers which can be used directly in diaper-making machines. The disposable articles so produced offer remarkable absorbing properties.
Abstract:
In opening and cleaning fibers an improved method to increase the proportion of usable fibers in processable textile fiber stock using a plurality of bale opening machines feeding fiber to a line of fiber cleaning and mixing machines, following which the fibers are fed to a plurality of carding machines. At least some of the machines settings are adjusted to remove a higher level of waste, including trash and good fiber, than would conventionally be acceptable. The waste from the machines is centrally collected and passed to a fiber retriever which removes good fibers to return them into the line of cleaning and mixing machines.
Abstract:
An apparatus for opening and cleaning fiber tufts, includes an opening roll, a feeding mechanism for advancing the fiber tufts to the opening roll; a screen disposed along one part of the circumferential surface of the opening roll and located downstream of the feeding mechanism, as viewed in the direction of rotation of the opening roll. The screen permits impurities, propelled by centrifugal forces, to pass therethrough. The screen is eccentric with respect to the opening roll. There is further provided a shroud disposed along one part of the circumferential surface of the opening roll and located downstream of the screen. The shroud is movably supported for assuming an open position in which fiber tufts may pass from an annular clearance between the opening roll and the screen to an outlet and a closed position in which passage of the fiber tufts is blocked from the clearance to the outlet.
Abstract:
The present invention consists of an apparatus and method whereby fibers such as cotton or otherwise are cleaned and carded prior to yarn formation to insure that the maximum quantity of fibers are utilized while removing substantially all non-lint from the fiber. Minimum fiber loss occurs while providing a sliver of excellent quality. The process herein includes the steps of carding the fibers whereby a portion of usable fibers, lint and other foreign matter are removed and are thereafter displaced to a condenser means. After condensing, the usable fibers which are still commingled with the waste are then extracted and recycled to the carding apparatus after blending with fresh stock in a uniform manner to provide a consistent blend for sliver formation or other uses.
