Abstract

The invention discloses a sand wash process for modal yarns. By the aid of the sand wash process, the problem of influence on the wearing comfort of underwear woven from existing modal yarns due to easiness in skin irritation after pile on the surfaces of the existing modal yarns already subjected to sand wash is in contact with human bodies can be solved. The sand wash process mainly includes four steps of sand wash, soft wash, pile removal and finishing and drying. The sand wash process has the advantages that processing and treatment are carried out by the aid of auxiliaries such as sand wash agents, cellulase and chitosan, accordingly, the modal yarns have unique old-fashioned feel, and the purpose of improving the wearing comfort of underwear woven from the modal yarns can be achieved.

Description

technical field [0001] The invention relates to a fabric washing process, more specifically, it relates to a sand washing process for modal yarns. Background technique [0002] Sand washing is a kind of water washing process. It refers to washing the fabric with alkaline additives. The alkali corrodes the fiber, making the surface of the fiber uneven and frizzy, making the fabric have a unique old feeling, and because of the alkali Corrosion, the originally relatively hard fiber structure becomes soft, making the fabric softer and more elastic. Sand washing is suitable for fabrics such as silk, rayon, cotton, linen and chemical fibers and their clothing. [0003] At present, the Chinese patent with the publication number CN104420164A discloses a sand washing method for silk garments, which includes three steps of sand washing, softening and grinding, and cold grinding. In order to achieve effective color retention and prevent over-treatment, the silk garments after treatmen...
