Roofing Material and Related Method
A roofing material including a bitumen or other hot melt coating disposed across a base sheet of stitch-bonded fabric incorporating a blend of standard and bi-component polyester staple fibers stitch-bonded with a plurality of parallel stitch lines of stitching yarn running in the machine direction. The bicomponent fibers may be heat activated and cooled prior to application of the hot melt coating thereby providing dimensional stability.

MODIFIED UREA-FORMALDEHYDE BINDERS FOR NON-WOVEN FIBER GLASS MATS
A method of forming a binder composition includes providing a urea-formaldehyde resin and combining one or more starch compounds with the urea-formaldehyde resin to form a starch modified urea-formaldehyde resin. The one or more starch compounds may be combined with the urea-formaldehyde resin so that the starch modified urea-formaldehyde resin includes about 1 wt. % to about 10 wt. % of the one or more starch compounds.

CARBON/CARBON COMPOSITES AND METHODS OF MAKING CARBON/CARBON COMPOSITES HAVING INCREASED FIBER VOLUME
A method of making a carbonized preform for a carbon-carbon composite brake disk may comprise: stacking a plurality of textile fabric layers, each textile fabric layer in the plurality of textile fabric layers including oxidized polyacrylonitrile (PAN) fibers, each textile fabric layer in the plurality of textile fabric layers being more uniform than a typical fabric layer formed from cross-lapping; each fabric layer being thinner than a typical fabric layer from cross-lapping, needling the plurality of textile fabric layers to form a needled non-woven board; cutting a fibrous preform from the needled non-woven board; and carbonizing the fibrous preform. The resultant non-woven carbonized preform maintains a higher fiber volume and more consistent properties throughout than what would otherwise be achieved using a typical fabric layer from cross-lapping.
Fire retardant mattress core cap and method of making same
A fabric made by the method of providing a non-woven batt having flame retardant fibers, stitch bonding the non-woven batt with an elastic yarn, and heat treatment the stitch bonded, non-woven batt. The stitch bonded non-woven batt is exposed to a temperature in a range of 65° C. to 200° C. for a period in a range of 30 seconds to 120 seconds, and contracts in the machine direction in a range of 5% to 65% and in the cross-direction in a range of 20% to 70%. In an embodiment, the fabric is adapted for use as a mattress core cover.

Hygiene product
The invention concerns a hygiene product comprising at least one layer of a nonwoven wherein the nonwoven layer comprises man-made cellulosic fibers wherein the layer or the layers has or have a rewet value of equal to or less than 30% and a liquid strike through time of equal to or less than 6 seconds for the use in disposable hygiene products, such as diapers, feminine pads and incontinence products or in wet wipes like toilet wipes, facial wipes, cosmetic wipes, baby wipes and sanitary wipes for cleaning and disinfection.

STITCHBONDED, WASHABLE NONWOVEN TOWELS AND METHOD FOR MAKING
A stitchbonded washable towel made from a stitchbonded fabric having a cellulosic nonwoven sheet of cellulosic fibers, and an integrated nonwoven sheet of an outer sublayer of wood pulp fibers, and an inner layer of textile fibers substantially entangled with the wood pulp fibers, and confronting the cellulosic nonwoven sheet of cellulosic fibers. The stitchbonded fabric as uses a pattern of stitching yarns that fixes the cellulosic nonwoven sheet to the integrated nonwoven sheet. A post-treatment of the stitchbonded fabric in a heated aqueous solution containing soil release polymer gathers the fabric into the towel, and provides stain and soil re-deposition resistance.
