Embodiment Construction
[0022] The embodiment of the present invention provides a production process of medical cotton loose fiber, the whole process mainly includes cotton loose fiber preparation, scouring, bleaching, neutralization, softening and finishing.
[0023] Specifically, see figure 1 As shown, the production process includes:
[0024] Step S110, opening the loose cotton fiber bag, removing the packing rope, hoisting it into a high-temperature and high-pressure yarn cooking pot for scouring;
[0025] Step S111, put 1 / 3 demineralized water into the bleaching equipment, then add a predetermined amount of caustic soda (amount: 5-10g / l), stabilizer (green environmental protection oxygen bleaching stabilizer, amount: 0.5-1.5g / l) and hydrogen peroxide, after mixing evenly, add the remaining 2 / 3 demineralized water, then add the scoured cotton loose fiber into the bleaching equipment, gradually raise the temperature to 95-100°C, and bleach for 55-65 minutes. Compare

The invention provides a production process of medical cotton fiber. The production process comprises the steps of opening a cotton fiber package, removing a packing rope, and hoisting into a high-temperature and high-pressure yarn boiling pot for scouring; adding 1 / 3 of softened water to bleaching equipment, then adding a preset amount of caustic soda, stabilizing agent and hydrogen peroxide, uniformly mixing, then adding all of 2 / 3 of residual softened water, then adding cotton fiber after scouring to the bleaching equipment, gradually increasing the temperature to 95 to 100 DEG C, bleaching for 55 to 65 minutes, wherein the bath ratio is kept 1:(8 to 10) in the whole process, then deoxidizing, neutralizing and washing with water; softening the cotton fiber after bleaching, then dehydrating and drying. According to the production process, in the condition that the product quality is not reduced, the production efficiency can be greatly improved, the production time can be shortened, and additionally, the environmental pollution is reduced by adopting an environmental process.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a production process of medical cotton loose fibers. Background technique [0002] Medical cotton is the abbreviation of medical absorbent cotton, which refers to the cotton loose fiber used in the medical and health care industry, such as medical cotton balls, cotton swabs, alcohol cotton and other sanitary materials. Medical cotton generally adopts cotton with poor quality below grade 5 (grade 6, grade 7). A more scientific and reasonable production process is required to produce medical cotton loose fibers that meet the regulations. [0003] In the prior art, taking sanitary material production enterprises in Shandong as an example, most enterprises adopt the two-bath two-step method of scouring and bleaching, and the work process is lengthy, wherein the scouring time is 6-10 hours, and the bleaching time is 24-30 hours , the production time of the whole production pr...
