Publication number: 20180274143Abstract: A nonwoven recyclable fabric and associated methods are provided. The fabric is formed from 100% polyester, and may also include surface coatings such as hydrophilic coatings to promote heat transfer as well moisture vapor transmission rates and/or a silicone coating to promote fabric smoothness and reduce abrasiveness of the fabric. The polyester fibers forming the fabric are obtained from a mixture of monocomponent high melt polyester fibers and bicomponent high/low melt polyester fibers. The bicomponent fibers have a high melt polyester core, and a low melt polyester outer sheath. The fibers are hydroentangled with one another. After entanglement, the low melt outer sheaths are melted to form a low melt binder interspersed with the high melt polyester fibers and the remaining high melt polyester cores. The binder fuses to these fibers to provide desirable strength characteristics.Type: ApplicationFiled: March 24, 2017Publication date: September 27, 2018Applicant: PURLIN, LLCInventor: Joseph D. Wahlquist

Patent number: 4929480Abstract: An absorbent structure for collecting and retaining exuded fluids from food products such as meat and poultry is disclosed herein. The structure has a fluid permeable top sheet and a fluid impermeable bottom sheet with an absorbent core of pulp coform material located therebetween. In a preferred embodiment the periphery of the top and bottom sheets are sealed to form a pouch and the pulp coform material is stratified into a first top layer and a second bottom layer. Superabsorbents such as carboxymethylcellulose may be added to the coform material to aid in fluid retention. In the preferred embodiment the superabsorbent is located in the bottom layer of pulp coform while the top layer of the pulp coform is substantially devoid of the superabsorbent.Type: GrantFiled: July 20, 1987Date of Patent: May 29, 1990Assignee: Kimberly-Clark CorporationInventors: David G.

Patent number: 4379192Abstract: An absorbent impervious barrier fabric in the form of a laminate has a fibrous section including a mat of polymeric melt blown microfibers and an impervious polymeric film adjacent said mat, said fibrous section and film being united in compacted bond regions formed by the application of heat and pressure and comprising pillars of bonds extending completely through the fabric from the outer surface where the fibrous elements are fused to the interface between the mat and the film where microfibers are fused to the film without disrupting the imperviousness of the film, the bond intensity tapering from said fused regions toward the essentially unbonded central plane of said mat to provide a double gradient in bond intensity in said pillars of bonds. One embodiment of the fabric has a fibrous section with a surface layer web of continuous and randomly deposited filaments and a microfiber mat with the web having intermittently discrete prebonded regions in addition to the compacted bond regions.Type: GrantFiled: June 23, 1982Date of Patent: April 5, 1983Assignee: Kimberly-Clark CorporationInventors: Joseph D. Wahlquist, Jay Shultz
