Designing a Braider for Sutures.

The design of a braiding machine for sutures and the economics of its manufacture depend on the availability of standardized components for a wide range of specifications. Easy access, despite a large track and gearing system, and mechanical stability are important aims in design. The guide on the end of the tension spring is both very li..

Production of Aligned Short fiber Composites with Novel Flow Processing Methods.

Experimenters fabricated a series of short fiber reinforced polymer matrix composites with a novel fiber alignment method that employed hydrodynamic flow through a multi-ply staggered mesh. Tests compared the tensile strength and elastic modulus of composites that were reinforced with the hydrodynamically aligned fibers with the correspon..

Breakthrough in Mass Production of Composites.

Cambridge Consultants (CCL), a United Kingdom based manufacturer of resin based reinforced composites, recently introduced a range of equipment for the mass production of three dimensional preforms from a variety of fibers. The new process, the details of which CCL has not yet released, facilitates different preform shapes that are reinfo..

Boosting Fiber Content in Composites.

Heinsco Limited recently developed Unifibre, a fiber reinforcement sheet based on tows. during fabrication, epoxy coated high tenacity polyester yarns--called tramp yarns--bind the tows into a thermally cured sheet. Because the spacing between the tramp yarns averages 200 centimeters, the tramp yarns represent only 0.3 percent of the tota..

Quality Control in the Carpet Industry.

PIV Electronics of Scunthorpe recently introduced its Posituft control system to help carpet manufacturers more accurately control yarn and fabric feed rates. According to the United Kingdom based company, the Posituft control system enhances the consistency of amchine made dimensional measurements, so much so that extremely precise speci..

Modern Trends in Carpet Backing.

The three types of backings used in the carpet industry include precoat, anchor coat, or back sizing; secondary or jute backing; and foam backing. Precoat, anchor coat, and back sizing involve the application of a latex compound with a lick roller or knife blade to anchor individual tufts to the primary woven fabric backing. Secondary jut..

Ford Seat covers from Poland.

As of autumn 1994, the Ford Motor Company will have some of its automotiv seat covers made in Poland. Seat covers will be made for the Escort automobile. The company will invest $50 million to consruct a new factory to produce the seat covers in Plonsk. The investment will result in the creation of 1,000 new jobs. Aoubt 600,000 covers wil..

Cellulose Based Packaging Material.

Environmental pollution from viscose yarn production processes can be reduced if the cellulose is dissolved directrly and not obtained by chemical reactions involving sulfur compounds. The monohydrate of N-methyl morpholine-N-oxide (NMMNO) is the most suitable solvent for direct cellulose dissolution. Research at the Thuringian Institute ..
