Abstract

A multi-layered article for bedding or clothing protection formed of a base layer and having a waterproof or water resistant side, together with a plurality of sheet layers, each sheet layer having a waterproof or water resistant side; and commonly welded together preferably with performations. The sheet layers are individually removable as needed.

1 . A multi-layered protector article comprising:
 a generally rectangular unfolded base layer; and   a generally rectangular upper portion including a plurality of removable layers overlaid on one another, said upper portion commonly adhered to and with said base layer by at least one weld, at least part of said at least one weld co-located in a line with a plurality of perforations where at least some of said weld is used to demarcate the perforations;   wherein each of said plurality of removable layers is defined by said plurality of perforations along at least one side and each said removable layer is individually removable from said article at said perforations, said article is formed at least in part using a bioplastic, and said article is at least in part biodegradable.   
     
     
         2 . The multi-layered article of  claim 1 , wherein said removable layer includes a waterproof membrane on at least one side. 
     
     
         3 . The multi-layered article of  claim 2 , wherein the side opposing the side with said waterproof membrane is comprised of at least one of cotton, rayon, polyester, bamboo, lyocell, hemp, or flax. 
     
     
         4 . The multi-layered article of  claim 2 , wherein said waterproof membrane is micro-porous or non-porous and has a thickness of at least 0.001 mm. 
     
     
         5 . The multi-layer article of  claim 2 , wherein said waterproof membrane includes a laminated side. 
     
     
         6 . The multi-layered article of  claim 2 , wherein the waterproof membrane comprises at least one of at least one of polyethylene, polyurethane, polyvinylchloride, polybutylene, latex, or silicone. 
     
     
         7 . The multi-layered article of  claim 2 , wherein said generally rectangular base layer further includes a portion arranged to wrap around the side of a mattress and elasticized edging for fitting to said mattress with each said waterproof layer functioning as a mattress protector. 
     
     
         8 . The multi-layered article of  claim 1 , wherein said at least one removable layer includes an unperforated tab. 
     
     
         9 . The multi-layered article of  claim 8 , wherein each layer of said plurality of removable layers is removable through use of said perforations and tab. 
     
     
         10 . The multi-layered article of  claim 1  wherein said at least one weld is an ultrasonic weld. 
     
     
         11 . The multi-layered article of  claim 1 , wherein said article is a clothing protector. 
     
     
         12 . The multi-layered article of  claim 1 , wherein said article is a seat cover. 
     
     
         13 . The multi-layered article of  claim 1 , wherein said article is formed, at least in part, of a non-woven material with a parallel or cross grain pattern with at least about 20 grams per square inch. 
     
     
         14 . The multi-layer article of  claim 1 , wherein a second side of each removable layer faces away from said base layer, and is formed of at least of non-woven fabric. 
     
     
         15 . The multi-layer article of  claim 1 , wherein said base layer includes an element for attaching to a person. 
     
     
         16 . The multi-layer article of  claim 1 , wherein at least one said removable layer, includes a water resistant layer. 
     
     
         17 . The multi-layer article of  claim 1 , wherein said perforations are arranged at least in part linearly in alignment with said at least one weld. 
     
     
         18 . A method of manufacturing a layered bed sheetset, comprising the steps of:
 forming a bottom fitted sheet including elasticized edging having a waterproof or water resistant side;   forming an upper sheetset comprising a plurality of sheet layers overlaid one over the next, each sheet layer having a waterproof side; and a comfort side; and   ultrasonically welding said plurality of sheet layers to said bottom fitted sheet along at least one ultrasonic weld line in a welding process;   wherein each said sheet layer includes at least one generally linear perforation, said perforation comprising a series of openings where said series extends generally linearly for a length at least approximately equal to the length of the bed for which the protector is intended.   
     
     
         19 . The method of manufacturing of  claim 18 , wherein the waterproof side of each sheet layer is attached to its respective sheet layer by heating or gluing. 
     
     
         20 . The method of manufacturing of  claim 18 , wherein said at least one ultrasonic weld line is coincident with said at least one generally linear perforation.
