NYLO N s A TRIUMPH OF CHEMICAL RESEARCH NOW IN N.Z "Nylon, 7> hailed in America and Eng land as the new high grade flbre for tex- tiles, will first reach New Zealand as bristles in toothbrushes. "Nylon" is & synthetic fbre produced Irom coal: air and water and was dis covered in 1938 as & result of ten years of intensive research instituted by Messrs_ du Pont de Nemours. It surpasses in strength and elasticity any known textile fbre, whether cotton, linen, wool, silk or rayon-~it is actually one and 8 half times stronger than silk: "Nylon" has many uses, 1t can be pro- duced in filaments a8 fine as 8 spider'$ web from which yarns of any size can be spun, and also in the form of bristles, rods, sheets, etc: Production and manufacture of "Nylon" yarns, fabrics and bristles is already advanced in U.S.A. Last year the amount produced exceeded 5,000,000 pounds weight. The bulk of this material went into the production of "Nylon" yarn and was used mostly for hosiery. In England to-day "Nylon" 18 being manufactured by Imperial Chemical Indus tries in two forms ~in yarn and bristles The war has restricted the large scale production of "Nylon" yarns, and "Nylon" hosiery will probably not be available until after the: war. The whole output of yarn has been taken over by the British Air Department for the manufacture of parachutes. "Nylon" bristle has considerable ad vantages over hog bristles in toothbrushes ~~it wears better and does not break ofr Or 80 soft in service. It absorbs only one ffth as much moisture a8 hog bristle and absorbs it more slowly. The surface of "Nylon" is smooth and hygienic, 1s not susceptible to bacterial attack, and does not become soggy and dirty in use: A recent test in a machine simulating the use of & toothbrush, the abrasion and fatigue was such that after 70,000 scrubs the "Nylon" brush was intact, with every tuft in place and only a few bristles out of alignment, whereas in & high grade hog bristle brush, subjected to the same test, the bristles were broken and flat tened down: "Nylon" toothbrushes made from this wonderful material are now manufac tured in New Zealand and will be released throughout the country during the next few days: They will be individually pack aged to reach you in" perfect condition_ and will cost n0 more than the ordinary high grade bristle brush: Ask your chem- ist 0r dealer to show you the new "Nylon toothbrushes every genuine "Nylon" brush has the word "NYLON" stamped prominently on the handle:
