Abstract
By the integration of electro-conductive properties in the fabric structure a
flexible textile can be obtained that does not reduce the quality of comfort,
maintenance and wearability of clothing. Each type of yarn has its advantages
and disadvantages, for example, metal coated polymer multifilament yarn has a
lower resistance to heat than metal multifilament yarn, but it is more flexible.
During this research conductive knitted patterns were made and tested. For the
experiments more suitable yarns for knitting were selected, which had a lower
resistance and were visually less changing of the knitted pattern in appearance:
silver coated multifilament polyamide, products of two different companies;
stainless steel multifilament yarn and polyester/stainless steel spun yarn. The
single-faced patterns of non-conductive yarn and straight and figural conductive
traces of conductive yarns were knitted. A test was made with the purpose of
finding out the electrical resistance of knitted textile affected by force. Knit
warm-up potency was researched during temperature measurement tests.
Knitting test pieces were also evaluated by aspect of technical structure and
visual appearance. Generally, it was concluded that steel yarns could not be used
for knitting while silver coated polyamide yarns are suitable for the manufacture
of knitted heating elements. As a result of this research, knitwear with a textile
heating element was made.
Keywords: electrically conductive yarn, electrical resistance, resistive heating
