| 6477740 | Stretch breaking of fibers An apparatus and method for stretch breaking fibers wherein the formation of relatively small (lengths less than 30 microns) fractured fibers is substantially reduced. This reduction is achieved by applying a dampening fluid to the bundle of fibers during... | 11/12/2002 |
| 4924556 | Stretch-break machine with drafting and breaking zones in superimposed levels A machine for stretch-break converting man-made fibers or fiber slivers, h the machine having one or more distortion zones, one of which can be embodied as a heating zone, and one or more breaking zones, whereby the distortion and breaking zones can be d... | 05/15/1990 |
| 4856146 | Comosites of stretch broken aligned fibers of carbon and glass reinforced resin A coating of a viscous lubricant applied prior to stretch-breaking permits forming slivers of stretch-broken carbon fibers. When an anti-static ingredient is added to the viscous lubricant cohesive slivers of stretch-broken glass fibers can be formed. Com... | 08/15/1989 |
| 4856147 | Composites of stretch broken aligned fibers of carbon and glass reinforced resin A coating of a viscous lubricant applied prior to stretch-breaking permits forming slivers of stretch-broken carbon fibers. When an anti-static ingredient is added to the viscous lubricant cohesive slivers of stretch-broken glass fibers can be formed. Com... | 08/15/1989 |
| 4771596 | Method of making fiber composite A fine heterogeneous hybrid spun yarn is blended from electrostatically conductive staple fibers and electrostatically non-conductive staple fibers so that the yarn is electrostatically conductive only over short discrete lengths. When used in pile fabric... | 09/20/1988 |
| 4569811 | Method of making a staple-fiber band A staple-fiber band is made by first spinning synthetic-resin filaments with spinnerets and drawing the filaments as roving at a predetermined feed speed from the spinnerets. The roving is then cooled without greatly stretching it so it has relatively hig... | 02/11/1986 |
| 4547933 | Process for preparing a high strength aramid spun yarn High strength, high modulus, continuous filament aromatic polyamide yarns are stretch broken under high tension while being sharply deflected in a lateral direction by mechanical means to provide a sliver which is processed by conventional means to a high... | 10/22/1985 |
| 4528050 | Producing filler material, particularly for cigarette filters Filler material, particularly for cigarette filters, is produced by feeding a first stream of substantially continuous filaments of filler material onto a pin roller which is driven at a speed such that the filaments are broken by the pins into irregular ... | 07/09/1985 |
| 4514880 | Formation of nonwoven webs or batts from continuous filament tow or yarn strands A method and machine for forming nonwoven batts containing refractory fibers such as carbon, glass, ceramic or metallic fibers, includes a conveying table (12) provided with scalloped rollers (90, 92) which separate tows of filaments (16) and spread the f... | 05/07/1985 |
| 4501046 | Method and apparatus for producing synthetic multifilament yarn A method and apparatus is provided for producing a synthetic multifilament yarn having the appearance, bulk and hand characteristics normally associated with spun yarns of staple fibers. The yarn is air jet textured to form loops, coils, bows and the like... | 02/26/1985 |
| 4477526 | High strength aramid spun yarn High strength, high modulus, continuous filament aromatic polyamide yarns are stretch broken under high tension while being sharply deflected in a lateral direction by mechanical means to provide a sliver which is processed by conventional means to a high... | 10/16/1984 |
| 4389751 | Apparatus for severing a fibre layer of staple fibres The present invention concerns an apparatus for severing a fibre layer (3) composed of mutually slidable staple fibres, and containing two driven pairs of rolls (9/10; 11/12) forming two nip lines for the fibre layer (3) guided therebetween. Severing is a... | 06/28/1983 |
| 4356690 | Fasciated yarn Fasciated yarn having uniform yarn construction and high strength, comprising a staple fiber group having a special staple assortment for making such a fasciated yarn.... | 11/02/1982 |
| 4080778 | Direct spinning process for stretch-breaking continuous filaments to form entangled yarn A zero twist, staple fiber yarn of good strength, outstanding cleanness and good uniformity is produced from continuous filaments by a direct spinning process followed by entangling to a pin count of less than 50 millimeters. Filaments of less than 70 per... | 03/28/1978 |
| 3945188 | Method of spinning synthetic textile fibers Method of spinning threads consisting at least partially of synthetic fibers comprising stretch-breaking continuous filaments to obtain fibers having staple length distribution similar to that of natural fibers, crimping said fibers, and open-end spinning... | 03/23/1976 |
