Effect on nylon

Low sling, low viscosity fluorescent coning oil. Imparts a super-white fluorescent effect on nylon. 

Non-mineral oil coning oil for use for use on nylon and polyester yarns. Most effective on nylon stretch yarns that are subsequently knitted into apparel containing rubber yarn. 

Imidazoline derivative. Powerful liquid cationic softener especially effective on nylon tricot knits. Excellent antistatic qualities. Is suitable for solvent applications. 

The DSC scans support findings from the XRD data, showing two distinct crystal structures arising in the polymer. Some contribution to this effect is expected from chain segmentation during the extrusion process (79, 20), however the effect on nylon 6 polymorphism due to the presence of clay is undeniable. 

Solvent bonding is suitable for all amorphous plastics. It is used primarily on ABS, acrylics, cellulosics, polycarbonates, polystyrene, polyphenylene oxide, and vinyls. Solvent welding is not suitable for crystalline thermoplastics. It is not effective on polyolefins, fluorocarbons, or other solvent-resistant polymers. Solvent welding is moderately effective on nylon and acetal polymers. Solvent welding cannot be used to bond thermosets.

Decabromododiphenyl Oxide—Polyacrylate Finish. This finish, effective on both polyester and nylon fabrics, is one of the most effective finishes available (ca 1993) for cotton—polyester blends (131). Relatively high cost and difficulty in appUcation may have prevented more widespread use. 

Alaige number of patents cover bis(ben2imida2ol-2-yl) derivatives (9) (48—50). Besides being effective on cotton, compounds of this type show good affinity for nylon.

Flame retardants designated for nylon include halogenated organic compounds, phosphorous derivatives, and melamine cyanurate (160—163). Generally, flame retardants are difficult to spin in nylon because of the high loading required for effectiveness and their adverse effects on melt viscosity and fiber physical properties. 

The crystallinity can be dismpted by substituents on the chains that interfere with the alignment process. Amorphous nylons are produced by deUberately engineering this effect, eg, nylon-NDT/INDT (also known as PA-6-3-T or PA-TMDT), which uses trimethyl-substituted hexamethylenediamine isomers combined with terephthaUc acid. 

The effect of temperature on properties can be seen in Figure 2, which shows the effect on modulus of increasing temperature of unmodified and glass-reinforced nylon-6,6. Impact strength, however, shows a steady increase with temperature as it does with moisture.

The data presented in Figure 19.7 were obtained on a Sonntag-Universal machine which flexes a beam in tension and compression. Whereas the acetal resin was subjected to stresses at 1800 cycles per minute at 75°F and at 100% RH, the nylons were cycled at only 1200 cycles per minute and had a moisture content of 2.5%. The polyethylene sample was also flexed at 1200 cycles per minute. Whilst the moisture content has not been found to be a significant factor it has been observed that the geometry of the test piece and, in particular, the presence of notches has a profound effect on the fatigue endurance limit. 

For some plastics, particularly nylon, the moisture content can have a significant effect on the creep behaviour. For such plastics, creep curves are normally available in the wet and dry states and a knowledge of the service conditions enables the appropriate data to be used.
