“…Treatment with an enzyme is a powerful cellulose composition, gives a clear look to the pile, and improves absorbency and softness. For this reason, biosingeing removes protruding fibers and slobs from fabrics, significantly reduces pilling, softens fabric hand, and provides a smooth fabric appearance [15]. Some researchers studied how to get quality products in dyeing and finishing process modification of textile fabric with an environmentally friendly process like biofinishing [16].…”

In the present day, numerous researchers have paid more attention to the dyeing and finishing quality of environmentally friendly textile products in the world because the lack of outstanding products is an alarming problem. Therefore, the purpose of the present study is to treat the fabric with cellulase enzymes to improve the dyeing and finishing quality. The effects of varying chemical concentrations, temperatures, and processing times were examined in the model and different process parameters were optimized in the preparation biosingeing process. The results of the Box–Behnken design were obtained as R2 = 0.7243, 0.9027, and 0.9966 for optimum absorbency, weight loss, and tensile strength, respectively. The treated fabric was analyzed using FTIR to know the unknown functional group and the chemical bonds on the fabric molecule. Testing of physical properties of the treated fabric was done and the result was comparable with other untreated fabrics. The treated fabric performance was studied at 40, 50, and 60 minutes and at temperatures of 30, 55, and 80°C. The experimental investigation has been carried out to determine the effect of biosingeing on different physical parameters, such as the tensile strength of treated cotton fabric (437 N), which was almost similar to that of the untreated fabric (443 N), with almost no significant differences. K/S value for the biosingeing fabric of treated fabric was 17.58, but the that of the untreated fabric was 15.6, which was significantly different. Thus, the enzymatically treated fabric is of good quality because the protruding fiber was removed in biosingeing process. This ecofriendly singeing preparatory process is an alternative process for terry towel fabrics.

“…Peningkatan ukuran molekul enzim selulase dapat dicapai dengan teknik imobilisasi. 2 Imobilisasi bioaffinity memungkinkan lebih banyak pengendapan enzim pada permukaan yang kecil, memiliki aktivitas katalitik yang lebih tinggi, meningkatkan stabilitas bila dibandingkan dengan enzim yang diimobilisasi menggunakan ikatan kovalen. 6 Produk T-shirt dengan bahan kapas sering adanya bulu yang timbul dipermukaan.…”

Tren fashion, khususnya proses pelusuhan pakaian jadi banyak dikerjakan untuk menghasilkan efek khusus agar memiliki kenampakan berbeda setelah pencucian. Proses pencucian dapat dikerjakan diantaranya biopolishing, stone wash dan acid wash/ice wash, hal ini dilakukan untuk memodifikasi produk akhir memberikan tampilan berbeda dan meningkatkan kemampuan kenyamanan pakaian. Proses biopolishing adalah proses penyempurnaan menggunakan enzim, bertujuan memperbaiki kenampakan, pegangan kain, sifat permukaan lebih halus, bebas pilling, dan memiliki daya serap tinggi. Penambahkan batu apung memperluas tingkat pelusuhan dibagian-bagian tertentu, dan memberikan tampilan berbeda.Percobaan menggunakan mesin washing skala laboratorium dengan variasi konsentrasi enzim 1%, 2% , dan batu apung 1/3 dan 1/2 suhu 60oC selama 30 menit pada mesin washing skala laboratorium. Pengujian meliputi pilling kain, pengurangan berat (SNI ISO 7211-6), ketuaan warna (SNI ISO 105-J03), ketahanan jebol cara diagfrgma (SNI ISO 13938-1), dan ketahanan gosok metode martindale (SNI ISO 12947-1). Hasil pengujian menunjukkan bahwa semakin tinggi penggunaan konsentrasi enzim dan batu apung, grade pilling semakin besar, pengurangan berat makin besar, tingkat ketuaan warna makin rendah, kekuatan jebol makin turun, dan semakin besar pengurangan tebal dan berat pada uji tahan gosok dengan metode martindale. Kondisi optimum diperoleh pada konsentrasi enzim 1 % dengan penggunaan batu apung 1/2 volume mesin washing skala laboratorium.

The purpose of this study is to select an appropriate commercial neutral cellulase enzyme for denim garments bio-polishing to achieve specific industrial goals. A full factorial experimental design was used to evaluate the effect of factors considered in the optimization of the bio-polishing process (fabric ID: x1, treatment time: x2, treatment temperature: x3, enzyme concentration: x4, storage time: x5, inactivation step: x6 and enzyme type: x7). Experiments were conducted using laboratory washing machine. Subjective evaluation was performed at a pilot and at an industrial scale. Tear, tensile strength and subjective evaluation concerning hand feel, fabric color, indigo dye pocket back staining and fuzziness extent were evaluated. Results showed that x6 and x7 had significant effects on the fabric tear and tensile strength loss. In the optimization, the great dependence between observed and predicted tear strength and tensile strength loss, the correlation coefficient of the models (R 2 > 0.85) and the important value of F-ratio proved the validity of the models. Results showed that denim leg panels treated with the enzyme Lava-Cell NSZ presented a minimum loss of tear and tensile strength. A low-temperature and time enzymatic bio-polishing process was developed at industrial scale.
