Abstract

The invention provides a novel ionic-liquid-based modified cotton fiber for infants and a preparation method of the cotton fiber. The method comprises specific operation steps as follows: (1) impurities on the surface of a cotton fiber are removed, the cotton fiber is washed clean and subjected to ball-milling treatment, a pre-opened cotton fiber is obtained and subjected to low-temperature oxygen plasma treatment, and a surface-activated cotton fiber is obtained; (2) scattered cotton is placed in an ionic liquid, water-bath heating and stirring are performed until complete dissolution, then waste silk is added, water-bath heating and stirring are performed continuously until complete dissolution, modified starch is added, the mixture is fully stirred, and a cellulose-protein mixed solution is obtained through filtration; (3) the surface-activated cotton fiber is impregnated in the cellulose-protein mixed solution, impregnated, taken out, washed with water and dried, and the ionic-liquid-based modified cotton fiber for the infants is obtained. According to the prepared modified cotton fiber for the infants, fold-resistant, washable and skin-friendly properties of the cotton fiber are improved, original physical properties of the cotton fiber are reserved, and the cotton fiber is green and natural.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a modified cotton fiber for infants based on ionic liquid and a preparation method thereof. Background technique: [0002] As we all know, there are many types of clothing for infants and young children, because the characteristics of infants and young children vary greatly in different periods in terms of body shape, physiology, and psychology during the growth process. All are different, so the styles and characteristics of clothing are ever-changing and very rich. [0003] Infants and toddlers are the most delicate and fragile period in a person's life. It is also a period of rapid growth and development. The metabolism is vigorous, but the development of various organs is not perfect, the functions are immature, the immune function is low, and the defense mechanism is poor. In view of the characteristics of babies who sleep a lot, sweat a lot, excrete ...
