Claims
- 1. A process of making a reinforced gasketing material having an improved reinforcing fiber therein, the process comprising the steps of:
- (a) applying, via fog box, approximately 4% (on weight of fiber) moisture to a tow of homopolymer acrylic fiber; and
- (b) feeding the moistened tow of homopolymer acrylic fiber into an input chute of a Buss-Condux 300/400-4 cutting machine at a rate of 4.0 lbs/min., the tow having an average denier per filament of 21, the tow having 0.1% (on weight of fiber) of a water soluble finish thereon; and
- (c) cutting the moistened tow of homopolymer acrylic fiber in the cutting machine in order to create a ministaple; and
- (d) regulating length of the cut tow by installing a screen in the cutting machine, the screen having 3/16 inch diameter round-shaped holes therein, the screen having an open area of 32.5%; and
- (e) combining the moistened, cut tow of homopolymer acrylic fiber with rubber in order to make a body layer mix, the acrylic fiber to rubber ratio having a value of substantially 2.0.
- 2. In a processe for manufacturing an improved reinforcing fiber for gasketing material, the process comprising the steps of:
- (a) applying, via fogbox, approximately 4% (on weight of fiber) moisture to a tow of homopolymer acrylic fiber;
- (b) feeding the moistened tow into an input chute of a Buss-Condux 300/400-4 cutting machine at a rate of 4.0 lbs./min., the tow having an average denier per filament of 21, the tow having 0.1% (on weight of fiber) of a water soluble finish thereon;
- (c) cutting the moistened tow in the cutting machine to create a ministaple; and
- (d) regulating the length of the cut tow by installing a screen in the cutting machine, the screen having 3/16 inch diameter round shaped holes therein, the screen having an open area of 32.5%.
- 3. A process for manufacturing reinforced gasketing material having a reinforcing fiber therein, comprising the steps of manufacturing the reinforcing fiber according to the process of claim 2 and thereafter combining the moistened, cut tow of homopolymer acrylic fiber with rubber in order to make a body layer mix, the fiber to rubber ratio having a value of substantially 2.0.
