PERFORMA KENYAMANAN TAKTIL KAIN RAJUT DARI BENANG CAMPURAN BIDURI

Abstract

Kenyamanan taktil merupakan salah satu aspek yang menentukan kenyamanan pada pakaian secara keseluruhan. Dalam studi ini, performa kenyamanan taktil pada tiga variasi kain rajut single jersey yang mengandung serat biduri, yaitu: thermolite -biduri (TB) 50%:50%, micropolyester -biduri (MB) 50%:50%, dan excel biduri (EB) 50%:50%, dibandingkan terhadap kain kapas (K) 100% dan poliester (PES) 100%. Kelima jenis kain tersebut juga divariasikan menjadi dua jenis kerapatan jeratan, yaitu rendah dan tinggi. Karakteristik kenyamanan taktil dievaluasi dengan menggunakan alat uji fabric touch tester (FTT). Hasil uji menunjukkan bahwa berdasarkan kriteria nilai primary sensory index (PSI), kain rajut dengan konstruksi kerapatan tinggi dapat menghasilkan nilai smoothness (kehalusan permukaan) , softness (kelembutan) , dan kenyamanan taktil total yang lebih baik dibanding kerapatan ABSTRACT Tactile comfort is one aspect that determines the overall comfort of the clothing. The work focused on studying performance relevant to the tactile comfort of single jersey knitted fabric. The fabrics were made using three fiber blending variation, include: thermolite-biduri (TB) 50%:50%, micropolyester-biduri (MB) 50%:50%, and excel-biduri (EB) 50%:50%. The 100% cotton (K) and 100% polyester (PES) fabrics were made as the comparator. All fabrics were also varied into low and high-density. Tactile comfort characteristics were evaluated using a fabric touch tester (FTT). The test results show that based on the criteria for the value of the primary sensory index (PSI), knitted fabrics with high-density construction can produce better smoothness, softness, and total tactile comfort values than low density. MB knitted fabric with a mixed composition of 50% biduri fiber and 50% polyester microfiber has the potential to produce better tactile comfort and softness characteristics than other fabrics, including 100% cotton and polyester. All high-density biduri knitted fabrics had higher warmness values than cotton and 100% polyester as comparator. TB knitted fabric with a mixed composition of 50% biduri fiber and 50% thermolite has the best warmness value compared to other fabrics.
