Abstract

The invention relates to a method for preparing super absorbent antibacterial blended cotton cloth. The method comprises the following steps: (1) swelling treatment; (2) carboxymethyl-modification treatment; (3) washing with warm water; (4) pickling and neutralizing; (5) washing with cold water; (6) sterilizing; (7) softening; (8) freeze-drying. The cotton cloth is prepared by blending alginate fibers and cotton fibers, and the alginate fibers have excellent softness, high using comfort, excellent antibacterial effect, high hygroscopic gelling property, excellent overall removable property, high oxygen permeability, excellent biocompatibility and excellent biodegradability and absorbability; the freeze-drying technology is adopted rather than the traditional drying or airing, so that air gaps of the cotton fibers in the swelling and freezing process are fully maintained, and the adsorption property of the cotton fibers is improved.

Description

technical field [0001] The invention relates to a preparation method of cotton gauze, in particular to a preparation method of highly water-absorbing and antibacterial blended cotton gauze. Background technique [0002] Medical absorbent gauze and medical absorbent cotton are the main hygienic materials used in the medical industry for wound dressing, protection, and cleaning of patients. The gauze can promote wound healing of patients, and the gauze has soft texture, low price, wide sources, simple production and processing process, and can be repeated and practical. The fibers in the existing medical absorbent cotton gauze generally have limited water absorption capacity, which cannot provide a moist environment for the wound, which is not conducive to wound healing, and it is easy to cause secondary adhesion of the wound, and in severe cases, it will cause infection. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the presen...
