Embodiment 1
[0054] Example 1 An unbleached and undyed knitted cotton textile prepared by an ecological cleaning method, the preparation process comprising:
[0055] (1) Pre-washing of knitted cotton textiles
[0056] Soak the knitted cotton textiles to be treated in a clear water environment system about 30 times the weight of the knitted cotton textiles, so that the knitted cotton textiles to be treated are completely infiltrated; then, the water temperature of the clear water environment system is raised to 30°C, and lipase is added, Carry out heat preservation treatment; Knitted cotton fabric is pure cotton fabric (100% cotton, gram weight 190g / m 2 , friction coefficient 3-4, bursting strength ≥ 500N); the amount of lipase in the clean water environment system is 0.5g / L; Fully react with lipids or other oily impurities on knitted cotton textiles to form water-soluble alcohols, fatty acids and other water-soluble impurities and remove them. The lipase is acid lipase; the enzyme activi...
Embodiment 2
[0070] Embodiment 2 An unbleached and undyed knitted cotton textile prepared by an ecological cleaning method, the preparation process comprising:
[0071] (1) Pre-washing of knitted cotton textiles
[0072] Soak the knitted cotton textiles to be treated in a clean water environment system about 30 times the weight of the knitted cotton textiles, so that the knitted cotton textiles to be treated are completely infiltrated; then, the water temperature of the clean water environment system is raised to 50°C, and lipase is added. Carry out heat preservation treatment; knitted cotton textiles are pure cotton fabrics (100% cotton, weight 190g / m 2 , friction coefficient 3-4, bursting strength ≥ 500N); the amount of lipase in the clean water environment system is 2g / L; Grease or other oily impurities on knitted cotton textiles are fully reacted into water-soluble alcohols, fatty acids and other water-soluble impurities to be removed. The lipase is acid lipase; the enzyme activity o...
Embodiment 3
[0087] Example 3 An unbleached and undyed knitted cotton textile prepared by an ecological cleaning method, the preparation process of which comprises:
[0088] (1) Pre-washing of knitted cotton textiles
[0089] Soak the knitted cotton textiles to be treated in a clean water environment system about 50 times the weight of the knitted cotton textiles, so that the knitted cotton textiles to be treated are completely infiltrated; then, the water temperature of the clean water environment system is raised to 40°C, and lipase is added, Carry out heat preservation treatment; knitted cotton textiles are pure cotton fabrics (100% cotton, weight 190g / m 2 , friction coefficient 3-4 grades, bursting strength ≥ 500N); the amount of lipase in the clear water environment system is 2g / L; Grease or other oily impurities on knitted cotton textiles are fully reacted into water-soluble alcohols, fatty acids and other water-soluble impurities to be removed. The lipase is acid lipase; the enzym...
