On the Treatment of Rayons with Synthetic Resins by Means of an Improved Method. (VI) : Introduction of a new (Wear) Tester of Universal Purposes Together with the Data and the Interpretation thereof using Samples of Fabrics and Filaments of Natural as well as Man-made Origin， especially Samples of the Special Resin Finish through “Pre-heating Quenching” Method

摘要

With a view to further elucidating the special resin finish through “Pre-heating & Quenching" method that one of the authors (N. S) has hitherto developed， a new type of tester has been contrived，which is also available for manifold purposes and for various kinds of samples in the forms of fabric as well as yarns and filaments. Various tests were made with fabrics and filaments of natural and artificial origin， including silk， ramie， cotton， wool， and nylon， vinylon， viscose rayon， acetate-rayon blends and Bemberg.The mechanism of the tester is rather simple， but the function is unique. It has been found that the inherent properties of each species of samples reveal themselves within each own graph or curve obtained through the testing data.Hence it can be possible to distinguish a truly converted and highly improved resin finish from its counterfeit of the same fabric by the comparison of the characteristic curves.On the basis of the same fabric also a successful finish through the “Pre-heating & Quenching" method could withstand to the tests in the practically significant region 3 ~ 4 times (and some indeed 10 ~ 13 times) as much as the ordinally finish on the market.It is also convenient for studying the properties of blends，being capable of measuring wash fastness of resin finish or abrasion fastness of dyeing.It is now being so planned as to be able to measure， by the use of this new machine and its attachments， static electrification or heat generation during flex and abrasion testing of the sampIe.By the advent of this new machine and through the interpretation some interesting facts， both theoretical and technical， have been revealed， and it is now expected that the tester will contribute to and throw a light upon the future betterment of the finishing in this line.
