Abstract
The alkali-hydrogen peroxide one bath process of medical absorbent cotton and absorbent gauze includes the following procedures: 1. hot water washing procedure, temperature is 60-180deg.C, washing for 10min; 2. kiering and bleaching procedure, placing NaOH whose concentration is 2-100g/L, hydroperoxide stabilizing agent whose concentration is 1-5g/L and cotton or gauze into reaction still according to the bath ratio of 1:15, heating to 10-100deg.C, retaining for 10min, then heating to 90-150deg.C, retaining for 60min, then discharging water; 3. hot water washing procedure, temperature is 90-150deg.C, washing for 10min; and 4. neutral water washing procedure, concentration of H2SO4 is 0.2-1.5g/L, washing for 30min.
Description
Technical field
Particularly a kind of medical absorbent cotton/gauze alkaline oxygen bath technology is handled in the degreasing, the bleaching that the invention belongs to fabric.
Background technology
The production technology of existing medical absorbent cotton or gauze is that soda boiling, chlorine float, pickling, oxygen are floated, neutral washing process, the operation multichannel line length of this technology, big energy-consuming, environmental pollution is serious, technology controlling and process requires tight, and product easily produces yellowing, the quality problems of turning to be yellow, become fragile.
Summary of the invention
The technical issues that need to address of the present invention are a kind of medical absorbent cotton/gauze one bath process of design, and its process route is short, power consumption is few, constant product quality.Technical scheme of the present invention is that a kind of medical absorbent cotton/gauze alkali-oxygen one bath technology is characterized in that: (1) hot water wash operation, temperature 60-180 ℃, washed 10 minutes; (2) boiling and bleaching process is 2-10g/L with concentration, NaOH, concentration be the H of 1.5-9g/L
2O
2, to be the bleeding agent of 1-8g/L, hydrogen peroxide stabilizer that concentration is 1-5g/L and cotton or gauze pack in the reactor by 1: 15 bath raio concentration, being warmed up to 50-100 ℃ kept after 10 minutes, be warmed up to 90-150 ℃ again, the heating-up time is 40 minutes, keeps draining after 60 minutes; (3) hot water wash process temperature 90-150 ℃, washed 10 minutes; (4) neutral washing step, H
2SO
4Concentration is 0.2-1.5g/L, washs 30 minutes.The present invention is owing to adopted the efficient stable agent and a purpose of finishing degreasing, bleaching and impurity elimination in bathing, thereby the present invention has compared with the prior art, and technological process is short, power consumption is few, the remarkable advantage of constant product quality.
