Abstract

The invention relates to a rope-form pretreatment process based on a low-alkaline scouring agent. The process comprises steps of batching, singeing, enzyme desizing, rope-form low-alkaline scouring with a two-step method and rope-form oxygen bleaching. The enzyme desizing efficiency is improved by the aid of an efficient penetrant, a sizing agent on fabric is effectively removed by using the low-alkaline scouring agent, and the use amount of alkali in the scouring process is reduced. The use amount of caustic soda is reduced while the pretreatment effect is guaranteed, the pH value of wastewater is reduced, and the biodegradability of the wastewater is improved.

Description

technical field

[0001] The invention belongs to the application technical field of textile printing and dyeing pretreatment, and relates to a rope pretreatment process of pure cotton fabric based on a low-alkali scouring agent. Background technique

[0002] Cotton fabric has the advantages of strong hygroscopicity, good warmth retention, and comfortable wearing, so it has become one of the most commonly used fabrics. However, the natural impurities on the cotton fiber and the size, auxiliaries and contaminants applied during the textile process have seriously affected the dyeing, printing, finishing and other properties of cotton fabrics. Therefore, the first process of dyeing and finishing cotton fabrics is Pre-treatment to remove natural impurities on cotton fibers and sizing applied during the weaving process.

[0003] Traditional printing and dyeing pretreatment processes mainly include rope pretreatment and flat width pretreatment. Compared with open width pretreatmen...
