Study on enzyme washing process of hemp organic cotton blended fabric

Abstract

Purpose At present, the enzyme washing process is widely used in hemp garment in the industry. However, it has many disadvantages. First, it is inefficient and labor-intensive, which can only be produced in small quantities and will take much time for workers to check. Second, its cost is high. The strength loss of the garment is up to 20 percent, with a bad damage. Presently, the enzyme washing process of the gray fabric is not industrialized. The purpose of this paper is to obtain a stable and efficient process for the enzyme washing of the gray fabric. Design/methodology/approach The whiteness, weight loss rate, strength, dyeing property and fabric style of enzyme washed gray fabrics were studied. Findings The results showed that the enzyme treated fabric has soft handle, smooth surface, good elasticity and high levelness, as well as low strength reduction rate under the optimized condition of bath ratio of 1:12, cellulase dosage of 0.3 percent, pectinase dosage of 1 g/L, treatment temperature of 55°C, treatment time of 80 min and pH of 6. Originality/value First, the process is environment friendly, green and sustainable and, second, it will make the industrialization of the enzyme washing process of gray fabrics, with a high commercial value.

Hemp as a potential raw material toward a sustainable world: A review

“…Fabric treated by sodium hydroxide with flame retardant compound improves the fire-retardant properties and fabric shrinkage [ 148 ]. Enzyme treatment [ 149 ] makes the hemp fabric softer, smoother, more elastic and highly leveled with minimal strength loss. When hemp is blended with wool, due to the increased amorphous are, it becomes less flammable [ 144 ].…”

Effects Optimization of Bio-Polishing Industrial Process Parameters

“…Textile products requirements have increased due to changes in the buyer's expectations and their awareness of quality and environment. It removes the weakened fibers and surface pills and significantly reduces pilling, resulting in smoother appearance and improved softness [6]. Cellulase is a complex enzyme system composed of endoglucanase (1,4-β-D-glucon 4-glucano-hydrolase), cellobiohydrolases (1,4-β-D-glucan cellobiohydrolase) and cellobiases (β-D-glucohydrolases) [7] [8].…”

A cleaning and reusable biochemical degumming method for hemp fibers through immobilized pectinase lyase on calcium alginate microspheres

“…Compared with the free enzyme, the immobilized enzyme can be reused many times and is easy to separate and recycle. 17 Calcium alginate is the most commonly used matrix for the immobilization of enzymes. The immobilization of enzymes on calcium alginate is an embedding method, which does not change the chemical properties of the enzyme.…”
