of sterilization wraps that are u201c sided u201d for other reasons while this has simplified the process of wrapping items this has also resulted in the unanticipated production of shear and pressure holes as discussed above it is desirable that sms material for use in this disclosure be made in the sequential manner as described above wherein the individual layers are deposited onto a moving forming belt first a spunbond fabric layer then a meltblown fabric layer and last another spunbond layer and bonded to form the laminate as noted above however the layers may be made separately stored for a time in roll form and unrolled and bonded together to form the laminate in a separate step in still another alternate method of manufacturing one or more of the layers e g the spunbond layer may be made separately and stored as a roll at a later time the spunbond layer may be unrolled and the other layers e g the meltblown spunbond formed and directly deposited onto the spunbond layer the disclosures have found that an asymmetrical sms laminate construction or one having differing basis weights between the two outer spunbond layers can reduce the number of pressure and or shear induced holes significantly if oriented appropriately relative to the application of use in addition when used as a gown fabric the asymmetrical sms can improve the attachment of ties to the gown in order to test this proposition numerous sms laminates of varying basis weights within the range of those used in sterilization wrap were produced symmetrical control fabrics and asymmetrical test fabrics as detailed in table 1 were tested using two methods a simulated use test and a sliding compression test the simulated use test compares the relative.
