Spandex: Opening Cases
Spandex: Removal of packages
The yarn should be used first in, first out as supplied. Do not use packages of different weights, sizes or age. The yarn tubes should be handled very carefully so that outside yarn layers are not disturbed. Outside yarn layers should not be touched.
The yarn should be loaded randomly in such a manner that tubes from the same box do not lie next to one another in the warp. If the creel is scheduled to be down for any length of time, then the tubes must be stored back in the original shipping cartons out of light and protected from atmospheric fumes.
Pre-tension Elongations – For those warping machines using a pre-tension feature, pretension is a function of the desired final warp beam elongation.

Care and Handling of Warp Beams
Storage of beams at temperatures above 95° F (35° C) or below 20° F (-7° C) should be avoided. These temperatures could cause adverse effects on processing performance.
