Abstract

|
This studies has been carried out how to effect on electrostafic propensity of synthetic fabrics by coating with 0.5% acrylic polymer solution which was previously developed by the author to improve anticrease nature of silk.
The work conditions are:
(A) Applied synthetic polymer was acrylic polymer 525, developed by the author.
(B) Electrostatic voltage for various fabrics were carried out by Korea standard abrasion method, KS K 0555.
(C) Applied fabrics for the investigations were carried out by using abrasion partner with Korea standard (KS K 0905) cotton, nylon, polyester and the self sample fabric.
(D) Electrostatic propensity investigations were carried out by use of sample as silk, nylon, polyester and acrylic fabrics, seperating before finish or after finish.
(E) Washing after the finish or the original fabric was carried out by Korea standard method, KS K 0465.
Through the investigations, be happened to find many interesting matters and the obtained results are as followings.
1. Electrostatic voltage for the finished fabrics increased more than their original silk, nylon, acrylic fabrics except polyester fabric. (See Table 5)
2. Electrostatic voltage for the finished polyster against K.S. polyester decreased remarkably than the original fabric test.
3. In spite of no problem on electrostatic propensity of silk, it showed high electrostatic voltage between the same nature fabric abrasion, because silk is very weak against abrasion and because the test method had been developed to be useful for only synthetic fabrics.
4. Electrostatic voltage increased more in case of abrasion between different nature of fabrics than the same nature of fabrics.
5. Electrostatic voltage of each fabric increased by repeat of wash.
6. Many investigation data were followed with Contact Electrification Series Principle, another word, the farther each other located fabric on the series abrasion was, the higher electrostatic voltage.(See Fig. 6)
7. Such investigation gives warning of use on the mix fiber spinning service as far as concern with electrification.
8. It may also call attention for such increase of electrification in case any finishing of silk textile.
