摘要

Process for embobinar an elastic fiber around a core package improved for elastic fibers, a process for forming a fiber elastic and the screen.It is disclosed a process for an improved embobinar elastic fiber on a core to form a package and / or a roll of warp for use in operations of knitting or weaving.The improvement comprises conforming elastic fiber to a form having a cross section of fiber such that the width of the fiber is at least three times the thickness of the fiber before embobinar fIbra in a package of supplies.Another aspect of the invention involves forming an elastic fiber using a spinning process of casting by extrusion with a matrix having one or more openings that have two or more axes geometric generatesLmente perpendicular, being that one of the geometrical axes is at least 1.5 and preferably at least about 3 times longer than the other geometric axis.The fiber of the present invention having an elongated cross section can be used to make the supply packages for knitted or woven cloth improved.And also for making non-woven fibre structures improved and improved binders.
