Abstract

The dyeing process with natural dyes has disadvantages, including poor color fastness. A mordanting process is required to overcome these disadvantages. Conventional mordanting processes often use metal salts. This research will substitute the mordanting process using surfactants as mordant substances. The pH of the process influences the application of dyeing with natural dyes. This study aims to determine the effect of the pre-mordant process using surfactants and the pH of the dyeing process on the color characteristics of cotton and silk fabrics dyed with Cocos nucifera L dye extract. The surfactants used were cationic and non-ionic polymeric surfactants. This study was conducted in phases. The first phase involved the extraction of coconut fiber, and the second phase involved pre-mordanting the fiber with surfactants. The third stage is the dyeing process, which has variations in pH 3, 7, and 9. The evaluation results show that cationic surfactants have the potential to be used as a mordant and provide an increased anti-bacterial effect on processed fabrics. The optimal use of cationic surfactants was obtained using a concentration of 9 g/L and pH 7 for the cotton dyeing process. The optimum concentration was obtained at 9 g/L for the silk dyeing process, and the dyeing pH was 3.

Abstract

Pengental memegang peranan penting dalam tingkat keberhasilan kualitas pencapan. Pada pencapan zat warna reaktif hasil optimum diperoleh dengan penggunaan campuran natrium alginat dan CMC. Pengental jenis natrium alginat memiliki waktu simpan yang singkat. Oleh karena itu, dalam penggunaannya perlu ditambahkan zat anti bakteri sehingga viskositas pengental tetap stabil. Salah satu zat anti bakteri alamiah yaitu daun sirih hijau. Sebelum digunakan, daun sirih hijau diekstraksi sampai diperoleh massa kental daun sirih hijau. Pengujian aktivitas anti bakteri dilakukan sebelumnya dan menunjukkan bahwa ekstrak daun sirih hijau dapat menghambat pertumbuhan bakteri dalam pengental induk. Penelitian dilakukan dengan penambahan ekstrak daun sirih hijau ke dalam pengental induk campuran dengan konsentrasi 0, 2, 5, dan 8 g/kg, yang disimpan dalam waktu kurun waktu 0 sampai 7 hari. Hal ini dibuktikan pada hasil uji aktivitas antibakteri dan viskositas pengental induk yang stabil hingga hari ke-7, berbeda dengan tanpa penggunaan ekstrak daun sirih hijau yang viskositasnya makin menurun drastis tiap harinya. Pada penggunaannya, makin banyak konsentrasi ektrak daun sirih hijau yang digunakan maka viskositas makin stabil dan ketajaman motif pun makin baik namun ketuaan warna makin menurun.

Abstract

A Characteristic often found in textile products is softness. The compound widely used as softener is silicone compound. The aim of this research is to determine the properties that will be obtained from the type of fabric being processed by comparing the use of silicon types, namely amino-propyl-functional polydimethyl siloxane (PDMS) and blocked amino silicone to each fabric. Firstly, research was conducted by varying the pH of the finishing process. Determined optimum pH will be followed by determining concentration of 15“60 g/L for each type silicone. The experiments was carried out on pad- dry- cure method. The tests carried out include fabric stiffness, tensile strength, resistance to repeated washing and heat, yellowing effect, Fabric Touch Tester and Water Contact Angle testing. It was found that there was no significant influence of pH on the use of amino-propyl-functional polydimethyl siloxane and blocked amino silicone compounds, so the next process was carried out at pH 7. Increasing the concentration of the softener will provide a better softening effect and optimum concentration at 45 g/L for both types of fabric used. Blocked amino silicone has better resistance to repeated washing compared to amino-propyl-functional polydimethyl siloxane. Heat testing shows that differences in molecular structure have no influence on both fabrics. Fabric processed using amino-propyl-functional polydimethyl siloxane provides a yellowing effect. Amino-propyl-functional polydimethyl siloxane provides good hydrophilicity. The softness value of blocked amino silicone is better performance on cotton fabric.
