Medical color cotton tela and its production

Abstract

This invention discloses one method for medical colorful gauze in 100% cotton, its procedure is as follows: A1, coat, using coating methods, colouring agent to the unilateral surface of the body of the gauze; B1, dry the colouring agent to form the finishing layer. This invention uses the method of coating instead of the ordinary disseminated Process. Because the gauze is not required to immerse with long time and tensile dry in the colouring agent, the completion time is short, the efficiency for production is high, the gauze produced by this method substantially saves the cost and improves product quality.

Description

【Technical field】 [0001] The invention relates to an all-cotton medical colored gauze and a production method thereof. 【Background technique】 [0002] In surgery, a blue or green or other cool-colored medical gauze is usually used, and the absorbed blood appears dark black, so as to eliminate the fear of red blood for patients and medical staff, and because the color is different from human organs It is convenient for medical staff to check and recycle. At the same time, medical colored gauzes of different colors are used by various medical staff participating in the operation during the operation, which is convenient for distinguishing responsibilities. [0003] The dyeing of this medical gauze usually adopts the traditional dip-dyeing method. But there are the following disadvantages: [0004] 1. The process is long and the process is complicated. The process flow is rolling-into the vat-wetting-dyeing-hot water washing 2-3 times-warm water washing 2-3 times-soaping-ho...

AI Technical Summary

Problems solved by technology

[0005] 2. The gauze dyeing process is long, repeated washing, a large amount of water loss, resulting in waste, increased cost and pollution;

[0006] 3. The fabric needs to be soaked for a long time, then stretched and dried, and the fabric is prone to shrinkage and stretching deformation such as weft skew and weft arc, which will lead to problems such as strength reduction and cloth surface grinding;

[0007] 4. The color of the dip-dyeing method is single; the production batch is limited by the equipment and lacks the flexibility of production
