The fabric is prepared by pre-impregnating the fabric, transversely stretching the fabric on a tenter frame, coating a latex composition on both surfaces of the fabric while maintaining the fabric in its transversely stretched condition, and after drying the fabric, overcoating one surface only of the coated fabric with a tackified, latex composition which may contain a chemical linking agent which enhances the bond between the elastomer and the fabric by forming a chemical bridge between them. A method for manufacturing coated fabric is also disclosed.Type: GrantFiled: October 15, 1985Date of Patent: January 20, 1987Assignee: Dayco CorporationInventor: Delmar D. Long

Patent number: 4624813Abstract: An elastomer coated bias fabric for reinforcing power transmission belts and the like is disclosed wherein one face of the fabric is provided with an uncured, tacky, carboxylated elastomeric composition. In one embodiment, the fabric is prepared by pre-impregnating the fabric with a neoprene latex composition followed by coating the neoprene composition on both faces of the fabric, and after drying the fabric, overcoating one face only of the coated fabric with a tackified, carboxylated neoprene latex composition. A method and apparatus for manufacturing the coated fabric is also disclosed.Type: GrantFiled: July 5, 1984Date of Patent: November 25, 1986Assignee: Dayco CorporationInventor: Delmar D. Long

Patent number: 4618512Abstract: Synthetic-cellulosic blended fabric is padded with a solution of nitrogen rich N-methylol crosslinking agent, acid catalyst, antimony oxide and a halogen containing alcohol; dried at about 140.degree.-190.degree. F. and then cured at about 250.degree.-400.degree. F. for sufficient time to impart smooth-dry and flame retardant properties to the fabric. Aqueous polyethylene or silicone emulsion softeners can be added to the padding solution if desired. Dibromoneopentyl glycol makes an exemplary halogen containing alcohol. The process can be varied to first pad with antimony oxide, dry, and then repad with a solution of: nitrogen rich N-methylol crosslinking agent, acid catalyst, and a halogen containing alcohol, dry again and cure, at the above specified temperatures.Type: GrantFiled: June 28, 1985Date of Patent: October 21, 1986Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Robert J. Harper, Jr.

Patent number: 4574107Abstract: A method for producing a coated woven fabric, in which the support material comprises disintegrable chemical weft threads which are subsequently removed without the other threads being affected, method wherein:a first support fabric is produced of which only part of the weft threads are disintegrable, and in a weave in which said disintegrable weft thread is so arranged that, were it to be removed, the result would be, not a woven fabric any longer, but a superposition of three criss-crossed layers of parallel warp threads, one layer of weft threads being squeezed between two layers of warp threads, respectively;then, said support fabric is coated with a coating composition;and finally, the deposited coating is gelled in the right temperature conditions to remove the disintegrable weft thread.Type: GrantFiled: September 7, 1984Date of Patent: March 4, 1986Assignee: Tissage et Enduction Serge Ferrari S.A.Inventor: Serge Ferrari
