ANALISIS KOMPARATIF KEKUATAN TARIK DAN KETAHANAN LUNTUR WARNA PADA VARIASI KONSTRUKSI KAIN TIE DYE PRODUKSI UMKM SURAKARTA

Testing and analyzing fabric quality is crucial in the fashion industry to ensure regulatory compliance and meet consumer expectations. Tie-dye fabrics, as increasingly popular products, require specific testing to ensure their quality and durability. This study aims to analyze and compare the strength characteristics of grey fabrics made from rayon and cotton before and after stamp batik and tie-dye treatments, as well as evaluate their color fastness to soap washing. Standard testing methods were employed to measure tear strength, tensile strength, and elongation in both weft and warp directions. Results showed that rayon fabric exhibited higher tear strength (1728 g weft, 1354.67 g warp) compared to cotton (1237.3 g weft, 1194.67 g warp). However, cotton demonstrated superior tensile strength (126.2 N weft, 293.64 N warp) compared to rayon (103.6 N weft, 189.006 N warp). Fabric elongation was higher in rayon (23.37% weft, 14.08% warp) compared to cotton (10.08% weft, 11.48% warp). Stamp batik treatment increased tear strength in rayon but decreased it in cotton, while both fabric types experienced decreased tensile strength and increased elongation. Tie-dye treatment resulted in decreased tear and tensile strength but increased elongation in both fabric types. This research provides valuable insights into the changes in fabric strength characteristics following stamp batik and tie-dye treatments, which can serve as a reference for the textile industry in optimizing production processes.
