H0 OH = where "-" and "~," respectively represent hydrogen bonds. As shown in the figure - Figure, it mainly includes: the following method: the weight of 15 to 25% of polyethylene Based on 1274798 (PolyviypyrroHdone, PVP) dissolved in 7〇~85% by weight of isopropanol or other alcohol solution' and uniformly stirred as &solution; 20~40% by weight of tetraethoxy Tetraeth(R) xysilane (TEOS) is dissolved in an amount of 6〇8% by weight of isopropanol (IPA) or other alcohol solution, and a predetermined amount of 0.03~0.1N hydrochloric acid or other inorganic acid is added. And stirring uniformly into a b solution; taking a predetermined amount of the a solution and the b solution by a sol-gel method at room temperature for a predetermined period of time, and evaporating the alcohol solution therein by a predetermined amount to produce a liquid PVP/ In the foregoing, the ratio of the composition of the a solution and the b solution is 25 to 55% by weight of the solution a, and 45 to 75% by weight of the b solution is the liquid PVP/Si described in the preferred embodiment. 〇2 mixed materials can also be placed in a vacuum oven Drying treatment, making it a solid Pvp/Si〇2 mixed material agent, as a backup, when it is used as a mixed material agent, it is placed in an isopropanol or other alcohol solution to reduce it into a liquid mixed material agent. The PVP/Si〇2 blended material prepared by the present invention is analyzed by FT-IR spectrum. As shown in the second figure, in the FT-IR diagram of the PVP/Si〇2 blended material, the pvp/ is not comparable. The Si〇2 mixed material agent has a distinct >C = 0 group absorption peak at 44cm 1 643cm, and gradually shifts to the low frequency region as the weight ratio of TE0S increases, while i〇78Cnri, 10 86C1T1, 1 082CHT1 There is also a distinct absorption peak, which is the Si-〇~Si group absorption peak, which proves that the synthesized pvp/s丨〇2 mixed material agent can be confirmed by Ϊ274798, and, due to pVp >c = 吸收 group absorption peaks have an offset phenomenon, which proves the existence of hydrogen bonds between the two. Further, when the PVP/Si〇2 prepared by the present invention is analyzed by c-NMR, as shown in the third figure, Different weight ratios of pvp/si02 mixed materials have 00 bases at 1 78 2, 1 78· 〇 and 1879·4 ppm, according to related techniques The report shows that in a mixed material, if a hydrogen bond occurs between two substances, it will cause a certain group to shift on the C-匪R pattern, and it is shifted to the high frequency region, and the result shows The PVP of the mixed chemical agent (> 〇 group will hydrogen bond with Si〇2 in the inorganic phase, and when the TEOS content is more, the higher frequency region shifts, and this result is related to pVP/ The FT丨R pattern analysis of the Si〇2 mixed material agent confirmed each other. As shown in the fourth figure, the PVP/Si〇2 mixed material agent of the present invention is subjected to TGA hot shell analysis. It can be seen from the figure that the initial decomposition temperature of the pvp/Si〇2 mixed material of different weight ratios will be As the amount of TE〇s increases, the decomposition rate decreases. This is due to the hydrolysis of TE0S in the mixed material to form S1(OH)4, and the process of polycondensation to form Sl2 is still SU0H)4 The polycondensation is completed, and this phenomenon is more obvious with the addition of TE0S. However, after the decomposition of Sl(〇H)4, most of the mixed materials are the network structure formed by pvp and Si〇2, and the decomposition rate is slowed down. That is, the thermal stability of the mixed material is relatively improved, and the more the TEOS content of the inorganic phase, the better the thermal stability. For the application of the PVP/Si〇2 mixed material prepared by the present invention in the fabric finishing process, a nylon (1^1〇11) fabric is taken as an example, and the nylon woven fabric is immersed in the dye solution previously disposed. 90 〇c under dipping for 45 minutes, and then 1274798' first for drying and then bagging, the above-mentioned 彡9 should be made of -p; colorant, or can be added to the hydrophilic agent and chlorine-resistant solid solution solution, 廿4 ~ MP / Si 〇 2 mixed material liquid injury,: a predetermined amount of water is stalked and mixed, forming - immersed in 4 times, then the configuration of the well immersed liquid γ pre-B And apply two. ^ ^ contact / another & hand slave, reach a pressure absorption rate of 80%, after the application of 75 ~ 850C, 1 ~ 3 points shovel eve cat private ..., buckle pre-drying treatment, And 145~1 550C, Z is the hot baking treatment of the clock, so that the fabric color does not form a coating layer, and the finishing process of the dyed fabric is completed. The dyed fabric is processed by the ρνρ "month rV1VSl〇2 mixed material agent to process the surface type energy, _#, as shown in the electron micrograph shown in the five figures of the heart, 〆, 'photograph ( A) shows that pure ρνρ矣; θ丄, sink ^ u , Ά the surface is smooth and flat, the bright film (B) shows that the surface is smooth..., the thousand whole kernels have small holes, the photo (C) is also the hole There is 'but the surface is not smooth and has overlapping, photos (8), (8) no U does not exist in the hole' and the particles are large and continuous, this is mainly

Because the amount of TE 0 S is less than 矣, # ^ it A ^ 颗粒 is formed by hydrolysis and polycondensation. The granules formed by the hydrolysis and polycondensation show a distinct hole. The diameter of the hole is extremely small, such as the attachment of the household. It is only about 2. 3nm~3·7nm. On the contrary, TEOS has more Si〇2 particles generated by Essence E) and mostly forms a three-dimensional arrangement of 'the particles are reduced in distance from each other even in a continuous shape, so the pattern presented is obviously granular. 'It is known that although the pores are too large, up to about 〇nm, the synthesized pvp/si〇2 mixed material agent of the present invention is applied to the dyed fabric finishing process, and the mixed material forming agent is coated. Layer holes can be up to nanometer size. As shown in Annex 2, the fabric is dyed and processed by the μ" 1274798 swin blending agent. The k/s value of the processed fabric can be seen from the chart. The pharmacy treatment, the pot color will become deeper, and as the proportion of Cong increases, the color will deepen. This is because the dyed fabric is sucked by PVP/Si() 2 (4), which is formed on the one hand. SlG2 particles promote the light to produce a refractive effect. On the other hand, the metal ions in the m-series have a complexation, so that the color of the processed fabric can be improved. However, the increase is *, and the Japanese towel has a limited degree. . The dyed fabric, the fabric, and the fabric which have been repeatedly sucked by the mixed material of the present invention have a higher fixing effect. Attachment - τ, the measured value of the moisture wicking and chlorine fastness of the dyed fabric, as can be seen from the chart, each fabric has a good effect on the hydrophilic part, and can be used in 5 The effect of completing the diffusion is achieved in seconds, and the relationship between the formation of the fabric on the surface of the fabric is slightly reduced, but the hydrophilic effect of the processed fabric after 5 times of washing is slightly reduced, especially in the processing of fabrics in which the fabric is not added with a hydrophilic agent. Even if it does not meet the standard of 5 seconds, it can be seen that the addition of the hydrophilic agent has a certain effect on the moisture wicking property of the processed fabric, but for example, the fabric is pressure-treated with a higher weight ratio of the pvp mixed material. The moisture absorption and wicking resistance are both good, and it is better than the compression only: VP poly: dyed fabric, thus showing the proper amount of si〇2, the PVP polymer formed in the 2 drug The fabric is less likely to be washed out, and has better resistance to illusion, whereas if it is not combined with W polymer, it may be easier to be washed out of the fabric PVP polymer. According to the above description, it can be concluded that the PVP/SA mixed material prepared by the preparation method provided by the present invention can be applied to the dyed fabric finishing plus 10 1274798, and the nano-holes are formed on the material. The coating layer, and the fabric dyed by the metal-synthesis salt dye of the drug-based material has the characteristics of perspiration and chlorine resistance, and the technology of Fang Hao, the effect of the cow, and the like, therefore, the present invention The proposed 〃 can provide a deep industrial value for the fabric manufacturing industry = simplification (4), the preparation of the application for the text.
