As shown in figure 1, the granules are prepared.
Thirdly, evaluation of the sterilization effect of the instant sterilization and virus removal master batch after washing in water
The prepared instant type sterilizing and virus removing master batch of comparative example 44, comparative example 45, comparative example 46 and example 42 was used for evaluating the sterilizing effect when washing clothes. Referring to the sterilization detection method of GB21551.5-2010 antibacterial, sterilization and purification functions of household and similar electric appliances-Special requirements of washing machines, standard washing materials are added into a common 10 kg washing machine without sterilization function: the bleaching medium plain cloth required by GB/T411 is characterized in that a kerchief of 330mm x 330mm is prepared by desizing treatment of 21 +/-2 counts of warp yarns and 21 +/-2 counts of weft yarns. Test sample cloth: the bleaching medium plain cloth required by GB/T411 is characterized in that 21 +/-2 counts of warp yarns and 21 +/-2 counts of weft yarns are subjected to desizing treatment to prepare square cloth with the thickness of 100mm multiplied by 100mm, and the total weight is 3 kilograms.
Uniformly coating 1mL of diluted bacterial liquid solution on each test sample cloth with the thickness of 100mm × 100mm, preparing 2 washing machines with the same model according to the operation method and referring to appendix A in GB21551.5, adding the instant antibacterial master batch into one washing machine, and not adding the instant antibacterial master batch into the other washing machine (see appendix A)As before), after the washing program is started and the washing is finished, the test cloth is taken out, the number of the residual viable bacteria on the test sample block is tested by a fire bacteria counting method, the bacteria to be detected are staphylococcus aureus and escherichia coli, and the concentration of the bacteria liquid is 1.0 × 109～9.0×109CFU/mL. The experiment was repeated 3 times, and the sterilization rate was calculated, and the average value, the amount of the instant antibacterial masterbatch and the sterilization effect are shown in table 7.
The calculation formula is as follows:
table 7.
The sterilizing effect is shown in table 7, when the addition amount of the instant antibacterial master batch is more than 0.1g, the sterilizing rate of escherichia coli, staphylococcus aureus and candida albicans reaches as high as 99.9%, and a good antibacterial effect can be achieved, when the addition amount of the instant antibacterial master batch is far more than 0.1g, the antibacterial effect achieved is basically the same as that when the addition amount is slightly more than 0.1g, but in specific application, the dosage can be adjusted according to the pollution degree of the washed clothes and different types of bacterial pollution, for example, the dosage of the polluted clothes in hospitals and the like can be properly increased, the capacity, the rotating speed and the power of different washing machines are different, and the dosage of the antibacterial master batch also has different dosages. In the embodiment, when clothes are washed, the addition amount of the instant antibacterial master batch is between 0.1g and 1g, so that the antibacterial fabric has a good antibacterial effect and can save resources.
According to the preparation of the guanidine salt polymer/polyethylene glycol composite antibacterial agent, polyethylene glycol contains a large number of hydroxyl groups, the polyethylene glycol has good water solubility, the polyethylene glycol with the molecular weight of 600-2000 is preferable, the polyethylene glycol with the molecular weight of 60000 has a slow dissolving speed in comparative examples 1-16, the polyethylene glycol has a slow water solubility and relatively poor compatibility with the guanidine salt polymer, undissolved solid particles are arranged on the surface of clothes after washing in a washing machine of comparative example 59, and the sterilization rate is low.
The guanidine salt polymer/polyethylene glycol/zinc-loaded antibacterial agent/zinc pyrithione/sodium dioctyl sulfosuccinate is prepared, the proportion of the zinc-loaded antibacterial agent in the comparative example 18 is too large, when the zinc-loaded antibacterial agent is uniformly stirred, the formed composite antibacterial agent has poor hydrophilicity and is not easy to be drawn into strips, and the sterilization effect after washing in the comparative example 61 shows that the sterilization rate of candida albicans (fungi) added with zinc pyrithione in the composite antibacterial agent is obviously superior to that of the composite antibacterial agent without zinc pyrithione. In comparative example 45, the master batch of dioctyl sodium sulfosuccinate was not added, after the washing machine was started, the degerming and virus-removing instant master batch was added, and after 20 minutes of washing, residual agglomerated zinc pyrithione particles were found on the clothes after washing, and the hydrophilicity of zinc pyrithione was poor, causing agglomeration, the washing time was short, and the agglomerates remained on the surface of the clothes fibers, easily causing clothes contamination. Meanwhile, the antibacterial rate of Candida albicans (fungi) is obviously better than that of the added sodium dioctyl sulfosuccinate. It follows that the weight ratio of zinc-loaded antimicrobial agent to zinc pyrithione is preferably 50: 50-70: 30; the weight sum of the zinc-carrying antibacterial agent and the zinc pyrithione and the preferable weight sum of the dioctyl sodium sulfosuccinate are 70: 30-90: 10; the total weight ratio of the guanidine salt polymer/polyethylene glycol composite antibacterial agent to the zinc-carrying antibacterial agent, zinc pyrithione and dioctyl sodium sulfosuccinate is 50: 50-95: 5, and the preferable weight ratio is 60: 40-90: 10.
The guanidine salt polymer/polyethylene glycol/zinc-loaded antibacterial agent/zinc pyrithione/dioctyl sodium sulfosuccinate composite antibacterial agent is compounded with a surfactant, a builder, water, sodium carboxymethylcellulose and essence, the spherical antibacterial master batches prepared in comparative examples 32-33 and examples 22-25 have the advantages that when the ratio of the guanidine salt polymer/polyethylene glycol/zinc-loaded antibacterial agent/zinc pyrithione/dioctyl sodium sulfosuccinate composite antibacterial agent is low, the antibacterial effect is poor, when the ratio is high, the dispersibility is poor, and the extrusion granulation efficiency is low, so that the weight ratio of the guanidine salt polymer/polyethylene glycol/zinc-loaded antibacterial agent/zinc pyrithione/dioctyl sodium sulfosuccinate is 50-80%; comparative examples 34 to 35 and examples 26 to 27 were conducted to obtain spherical master batches, which were dried when the water content was too low, and which were easily broken when the strand was pulled, and which were easily cracked, and which were too thin and could not be formed when the water content was too high, and which were easily adhered to the wall, and which were difficult to produce, and the weight ratio of water was 10 to 30%; comparative examples 36 to 37 and examples 28 to 30, when the content of the spherical master batch was too low, it was found that the extrusion stretching rate was reduced, the surface smoothness of the antibacterial master batch was reduced, the solubility of the antibacterial master batch after stirring in water was poor, after washing, particles remained on the surface of clothes, which were inconvenient to clean and wash, and when the content was too high, it was found that more foam substances were precipitated on the surface of the particles during extrusion granulation, and thus, sodium dodecylbenzenesulfonate was obtained in a weight ratio of 3 to 5%; the spherical master batches prepared in comparative examples 38-39 and examples 31-32 have the advantages that when the content of sodium carbonate is too high, the alkalinity of a washing system is easily too high, and when the content is too low, the oily stains on polluted clothes are not easily removed, and the sterilization rate is influenced, so that the weight part ratio of the sodium carbonate is 1-2%; the spherical master batches prepared in comparative examples 40-41 and examples 33-35 have the advantages that when the proportion of the hydroxymethyl cellulose is low, the viscosity is insufficient, the strip cannot be drawn out, and when the proportion is too high, the viscosity is too high, the strip is extruded and broken, so that the weight part ratio of the sodium carboxymethyl cellulose is 3-20%; the spherical master batches prepared in comparative examples 42 to 43 and examples 36 to 37 have high essence content and too much smell, and have insignificant smell when the essence content is low, and the preferable content is 0.02 to 0.2 percent. If guanidine salt polymer/polyethylene glycol/zinc-carrying antibacterial agent/zinc pyrithione/dioctyl sodium sulfosuccinate are compounded with surfactant, builder, water, sodium carboxymethylcellulose and essence, the comparative example is not suitable, and the spherical antibacterial master batch cannot be successfully prepared.
When the spherical master batch is mixed with sodium stearate, the sodium stearate micro powder is too much, the powder is easy to fall off, the instant solubility is influenced, the sterilization efficiency is low during washing, the sodium stearate micro powder is too little, the surface is sticky and easy to adhere, and after the spherical master batch is placed for 2 months, the water retention rate of the particles is low, and undissolved granular substances exist in the particles during washing; the sodium stearate mesh is low excessively, and the granule is coarse, and the surface coating is incomplete, and the antibiotic globular size of making is inhomogeneous, and the roughness, the sodium stearate mesh is too high, and the granule is fine, and in low-speed mixer, the surface can only adhere a small amount of sodium stearate, and the sodium stearate layer of cladding is too thin in the capsule machine, and the easy fracture of sodium stearate layer on antibiotic ball surface falls the powder, follows from this, and the proportion of globular antibiotic granule and sodium stearate is 95: 5-99: 1, the particle size of the sodium stearate micro powder is preferably 300-500 meshes.
