Abstract

The invention belongs to the technical field of textile finishing and processing, and particularly relates to a continuous processing method for a durable yellowing-resistant high-whiteness cotton type fabric. Pure cotton grey cloth is sequentially subjected to singeing, desizing, boiling-off, bleaching and mercerizing processes to obtain a semi-finished pure cotton fabric; the pure cotton fabricis padded in whitening finishing liquid, and the pick-up rate of the fabric is controlled to be 60-65%; then steaming fixation and floating color removal are carried out; and finally, the whitened fabric is subjected to soft finishing and rolling. According to the continuous processing method for the durable yellowing-resistant high-whiteness cotton type fabric, a whitening formula is reasonable in configuration, the whiteness of the whitened fabric under a CIE D65 light source reaches 160, the anti-phenol yellowing level of the fabric reaches the level 4 and above, the yellowing level of thefabric after the fabric is placed at 40 DEG C for 30 days reaches the level 4 and above, and the wearing performance of the high-whiteness cotton type fabric is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of textile finishing and processing, and in particular relates to a method for continuously processing durable yellowing-resistant high-white cotton fabrics. Background technique [0002] Pure cotton, cotton / nylon, and cotton / polyester products are mostly white, and the fabric is prone to yellowing during storage and long-term storage, resulting in a large decrease in whiteness, and the original high whiteness quality cannot be achieved after rework, which affects the quality of the fabric. Wear performance. These problems have seriously hindered the further development of high-quality white cotton type fabric. [0003] Patent CN 105297392B discloses a high-whiteness pure cotton fabric processing technology, through singeing, desizing, scouring, oxygen bleaching, mercerized fabric, padding whitening solution, steaming, washing and drying, and then Stretching, pre-shrinking. The technology disclosed in thi...
