Patent number: 11905626Abstract: The present invention provides an easy settable stretch fabric comprising three types of yarns: a rigid fiber, an elastic fiber, and a low-melt fiber, wherein the low-melt fiber comprises low-melt polymer which can be fused in the temperature between 60° C. to 200° C., being higher than the temperature used for normal textile process and household laundry, but lower than the temperature used for heat setting elastic fiber. The low-melt fiber can be selected from a group of fibers made from modified polyester, nylon, and polypropylene and the copolymer from them in the form of staple or filament.Type: GrantFiled: December 24, 2015Date of Patent: February 20, 2024Inventors: Tianyi Liao, Geoffrey D. Hietpas, Brian Scott Alcott

Patent number: 8252706Abstract: A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.Type: GrantFiled: March 1, 2006Date of Patent: August 28, 2012Assignee: INVISTA North America S.àr.l.Inventors: Dimitri P. Zafiroglu, Geoffrey D. Hietpas, Debora Flanagan Massouda, Thomas Michael Ford, Patricia A. Ford, legal representative

Publication number: 20120100351Abstract: Included are bonded laminate constructions that have a modulus which approaches the sum of the modulus of the individual components of the laminate. By reducing variation in the modulus, the stretch or elasticity of the bonded or laminated fabric or garment is maximized. The bonded laminates include a bonding component that may be an elastomeric film, an adhesive, or a combination of a film with adhesive.Type: ApplicationFiled: May 7, 2010Publication date: April 26, 2012Applicant: INVISTA North America S.a.r.l.Inventors: Carmen A. Covelli, Douglas K. Farmer, Geoffrey D. Hietpas

Patent number: 7310933Abstract: The invention provides a bicomponent staple fiber comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) wherein the bicomponent fiber has a substantially oval cross-section shape having an aspect ratio A:B of about 2:1 to about 5:1 wherein A is a fiber cross-section major axis length and B is a fiber cross-section minor axis length, a polymer interface substantially perpendicular to the major axis, a cross-section configuration selected from the group consisting of side-by-side and eccentric sheath-core, a tenacity at 10% elongation of about 1.1 cN/dtex to about 3.5 cN/dtex, a free-fiber length retention of about 40% to about 85%, and a tow crimp development value of about 30 to 55%, and a spun yarn comprising the bicomponent staple fiber.Type: GrantFiled: October 10, 2006Date of Patent: December 25, 2007Assignee: Invista North America S.ar.l.Inventors: Geoffrey D. Hietpas, Steven Wayne Smith

Patent number: 7036299Abstract: A spun yarn of cotton (35 wt %-80 wt %) and a bicomponent staple fiber (20wt%-65wt%) of poly(ethylene terephthalate) and poly(trimethylene terephthalate) based on total weight of the spun yarn. The spun yarn has a total boil-off shrinkage of about 22%. The bicomponent staple fiber component has a tow crimp development value of about 35%-70%; a tow crimp index value of about 14%-45%; a length of about 1.3-5.5 cm; and a linear density of about 0.7-3.0 decitex per fiber. The difference between the crimp index and the crimp development values is about 24%-35% absolute.Type: GrantFiled: December 19, 2002Date of Patent: May 2, 2006Assignee: Invista North America S.a.r.l.Inventors: Geoffrey D.
