- Description
-
Careful inspection is given every pirn or shipping bobbin of textile nylon yarn before it is wrapped and packaged. The inspector is one of a large group that makes sure every package is in proper condition for the manufacturer when it leaves the DuPont plants at Seaford, Delaware; Martinsville, Virginia and Chattanooga, Tennessee. Nylon for tire cord and industrial product is made by Du Pont in Richmond, Virginia.

- Description
-
Several ends of the sliver prepared in the Campbell tow-cutting machine are here entering a second machine and passing under a fluted roll into a gill box, the fallers of which may be seen at the left end. This second stage of the tow-to-top operation further blends drafts and condenses the sliver, which is then, as in the case of the DuPont Fiber D rayon shown here, drawn into yarn for rugs.

It gives protection to tiny filaments during knitting or weaving. After sizing, yarn is stored in a controlled atmosphere for 36 hours to permit the solution to set. Knitters and weavers boil off the solution in the final manufacturing step.

Rayon tow is here being converted into top on a machine invented by N.S. Campbell, of Greenwich, Connecticut. The operator has inserted several ends of DuPont Fiber-D rayon tow into the far end of the machine. They then pass between a pair of helical sheers, the upper member of which can just been seen at the top of the machine. The cutter cuts the tow diagonally to convert the continuous filaments into short fibers or a given length, which then feed into a gill box, at the center of the...
Show moreRayon tow is here being converted into top on a machine invented by N.S. Campbell, of Greenwich, Connecticut. The operator has inserted several ends of DuPont Fiber-D rayon tow into the far end of the machine. They then pass between a pair of helical sheers, the upper member of which can just been seen at the top of the machine. The cutter cuts the tow diagonally to convert the continuous filaments into short fibers or a given length, which then feed into a gill box, at the center of the machine. The web of cut fibers is seen emerging from the gill box and passing into a dynamic funnel, assisted by the arrangement of guide belts. The funnel and controller put a false twist into the condense web. The resulting sliver, being wound on the tube in the foreground, has thus been made without benefit of cards and combs.

Rayon tow, manufactured by the DuPont Company, is here being fed into a Perlok tow-to-top machine. The bands of continuous filaments are broken between the sets of rollers at the right without ever losing their original parallelism. In the producing of top by this method, the entire carding and combing process is bypassed.

- Description

Many of the qualities of nylon which make it so outstandingly suitable for brush bristles of all kinds, sutures, fishing leaders and tennis strings are dependent upon the step of drawing or stretching the filament after it has been formed by the spinning machine. This photograph shows spools of nylon filament being soaked in water in preparation for being stretched.

Production of nylon is a complex art requiring super cleanliness and rigid control of temperatures and pressures. In the manufacture of yarn at the textile fiber plants, the nylon salt solution is first piped into evaporators where much of the solvent is removed to form a more concentrated solution. This flows into an autoclave-like a giant pressure cooker-where small molecules link up to form long chain-like molecules. When this is completed, the nylon is a molten syrupy material. It flows...
Show moreProduction of nylon is a complex art requiring super cleanliness and rigid control of temperatures and pressures. In the manufacture of yarn at the textile fiber plants, the nylon salt solution is first piped into evaporators where much of the solvent is removed to form a more concentrated solution. This flows into an autoclave-like a giant pressure cooker-where small molecules link up to form long chain-like molecules. When this is completed, the nylon is a molten syrupy material. It flows from a slot in the bottom of the autoclave onto the surface of a broad, slowly revolving casting wheel. A shower of water hardens the polymer into a translucent milk white ribbon, which is then chipped up into small flakes. The nylon chips from several autoclaves are blended and poured into hoppers. Grids melt the flakes and a carefully designed pump forces the viscous molten nylon through the fine holes of a spinneret to form the yarn filaments, which solidify as they hit the air. The filaments are gathered into a yarn and wound on bobbins (above). The yarn is later stretched, or drawn to increase its strength. The DuPont Company makes the yarn but does not manufacture fabrics, hosiery or other finished products from nylon. It sells the yarn to other companies which transform it into the competed consumer products.
