Preparation method of soluble textile material with knitted structure

Abstract

The invention relates to a preparation method of a soluble textile material with a knitted structure, and relates to the field of medical dressings. The method comprises the following steps: weaving yarns to obtain a yarn fabric; carrying out modification treatment on the yarn fabric to obtain a modified yarn fabric; the modified yarn fabric is sequentially cleaned and dried, and the soluble textile material is obtained. In the preparation process of the soluble textile material, yarns are woven to obtain a weft-knitted spacer fabric and a yarn fabric with a three-dimensional structure, and after the yarn fabric is obtained, the yarn fabric is modified, dried and cleaned to finally obtain the soluble textile material. The soluble textile material obtained through the preparation method has a three-dimensional structure and soluble substances, under the application scene of medical binding, the three-dimensional structure can enable the soluble textile material to contain more liquid, the effect of the soluble textile material is fully played, and then the hemostatic performance of the textile material is improved.

Description

technical field [0001] The application relates to the field of medical dressings, in particular to a preparation method of a soluble textile material with a knitted structure. Background technique [0002] In medical scenarios, hemostatic materials are usually used to stop bleeding on patients’ wounds, as a pre-step for wound diagnosis and treatment. Among the hemostatic materials, soluble hemostatic materials have the same hemostatic effect due to their special properties that they can form gels when they meet liquids. It is superior to other types of hemostatic materials. [0003] Based on clinical medical practice, the following requirements are put forward for the application scenarios of biodegradable medical hemostatic materials: they need to have good biodegradability, plasticity and certain mechanical strength. In this case, in the related art, woven fabrics and nonwoven fabrics having a certain mechanical strength are generally used. [0004] However, since both t...

AI Technical Summary

Problems solved by technology

[0004] However, since both woven and non-woven fabrics have a planar structure, the ability to absorb liquid is limited, which will lead to ineffective soluble performance of the hemostatic material, thereby affecting the hemostatic performance

That is to say, the hemostatic material in the related art is limited by its own structure in the use scene, and cannot exert good hemostatic performance
