At present, some functional knitted fabrics appear in the market, have special effects of radiation protection, sterilization, fire prevention, heat insulation and the like, particularly have heating, warm keeping and heat preservation effects, are wide in application range and large in market demand, and are widely researched.
For example, a production process of an intelligent heating knitted fabric is disclosed in the chinese patent application with the application number of cn201510581480.x, and belongs to the technical field of textile processes. The application comprises the steps of uniformly mixing polyester fiber master batches and far infrared ore powder master batches, sequentially performing drum drying, melt spinning, forming, winding and barrel dropping, bundling, drafting, cutting and packaging, spinning, weaving and grey cloth finished product processes, and preparing the thermal underwear through a garment processing process, wherein the polyester fiber emits far infrared rays through far infrared emission particles dispersed in the polyester fiber to provide heat insulation and health promotion effects.
In view of the above-mentioned related technologies, the applicant believes that the far infrared mineral powder is doped into the fiber, which improves the heat retention performance of the fabric less, and cannot achieve a good heat retention effect.
Content of application
In order to solve the problem that far infrared mineral powder is doped into fibers to improve the heat preservation effect of the fabric to a small extent in the related art, the application provides the heating and heat preservation knitted fabric and the preparation method thereof, and the prepared fabric has more excellent heat preservation performance.
In a first aspect, the application provides a heating and warm-keeping knitted fabric, which adopts the following technical scheme:
the heating and warm keeping knitted fabric is provided with a heating and warm keeping coating, and the heating and warm keeping coating is prepared from the following raw materials in parts by weight:
polyvinyl alcohol: 20-50 parts of a solvent;
film-forming auxiliary agent: 10-15 parts;
far infrared master batch: 10-25 parts;
antioxidant: 0.03-1 part;
deionized water: 60-80 parts;
the far infrared master batch is aluminum-doped zinc oxide/hollow glass bead composite powder.
By adopting the technical scheme, the aluminum-doped zinc oxide/hollow glass bead composite powder is adopted in the heating and warm-keeping coating, so that the far infrared heating function of the fabric is enhanced, the heat-insulating property of the fabric is improved, and the warm-keeping effect of the fabric is effectively improved.
Preferably, the aluminum-doped zinc oxide/hollow glass bead composite powder is prepared according to the following steps:
s101, adding hollow glass beads and hydroxypropyl cellulose into deionized water, performing ultrasonic treatment for 10-15 min, and fully dispersing to obtain a suspension;
s102, dropwise adding a pH regulator into the suspension, controlling the pH of the suspension to be 2-4, and then adding Zn (CH) at the rotating speed of 1000-1200 rpm3C0O)2.2H20 and Al (NO)3)3.9H20, stirring for 7-10 h, heating to 70-90 ℃, and continuing stirring for 5-6 h to obtain gel;
and S103, aging the gel at a constant temperature of 105-125 ℃ for 10-12 h, taking out, sequentially washing with alcohol and water, filtering, drying, and calcining at a temperature of 600-700 ℃ for 3-4 h to obtain the aluminum-doped zinc oxide/hollow glass microsphere composite powder.
By adopting the technical scheme, the hollow glass beads are hollow spheres, and the closed small holes are formed in the hollow glass beads, so that the heat transfer inside and outside the fabric can be effectively reduced, and the heat insulation and warm keeping effects of the fabric are improved. Meanwhile, the aluminum-doped zinc oxide film is prepared on the surfaces of the hollow glass bead particles by adopting a sol-gel method, and the zinc oxide film can absorb heat radiation of a human body and feed back to the human body in a far infrared mode due to the far infrared effect, so that the loss of heat of the human body is reduced, the blood circulation of the human body is promoted, and the heating and warm-keeping effects are realized. In the high-temperature heating process, aluminum is doped into zinc oxide lattices, so that the zinc oxide lattices are distorted, the reflectivity of the oxide film layer to far infrared rays is favorably improved, and the warm-keeping effect is further improved.
Preferably, the hollow glass microspheres are mixed with (Zn (CH)3C0O)2.2H20/Al(NO3)3.9H20) The weight ratio of (5) to (10) is 100.
By adopting the technical scheme, (Zn (CH)3C0O)2.2H20/Al(NO3)3.9H20) The doping amount of the zinc oxide is too low, an aluminum-doped zinc oxide film which fully coats the hollow glass beads cannot be formed, and the infrared reflectivity is small(ii) a When (Zn (CH)3C0O)2.2H20/Al(NO3)3.9H20) The doping amount of the hollow glass beads is too high, the thickness of the doped zinc oxide film is gradually increased, the volume of the hollow glass beads is gradually increased, the specific surface area is reduced, the reflection effect on infrared rays is not improved, and the heat preservation effect is reduced.

Table 3 far infrared performance test results of heating warm-keeping knitted fabric
And (3) analyzing test results:
(1) by combining examples 1-17 and comparative examples 1-3 and table 2, it can be seen that the heating and warm-keeping coating prepared by adopting the aluminum-doped zinc oxide/hollow glass bead composite powder can effectively improve the warm-keeping performance of the fabric. The reason for this is probably that the hollow glass bead particles have hollow pores, the interior of the hollow glass bead particles contains static air, and the static air is loaded on the surface of the fabric, so that the heat conduction function of the fabric can be reduced, and the heat preservation effect can be achieved; meanwhile, an aluminum-doped zinc oxide film layer is formed on the surface of the hollow glass bead by a sol-gel method, so that a far infrared effect can be generated, heat radiated outwards by a human body can be absorbed, far infrared rays are reflected, the heating effect is achieved, and the heat preservation performance of the fabric is further improved.
(2) As can be seen by combining examples 1-6 with tables 2 and 3, the weight of the hollow glass microspheres added was compared to (Zn (CH)3C0O)2.2H20/Al(NO3)3.9H20) The weight ratio of the two is within 100 (5-10), and the prepared heat-emitting material generates heatThe thermal insulation fabric has good thermal insulation performance. The reason for this may be that (Zn (CH)3C0O)2.2H20/Al(NO3)3.9H20) When the doping amount is too low, an aluminum-doped zinc oxide film which fully coats the hollow glass beads cannot be formed, and the infrared reflectivity is low; when (Zn (CH)3C0O)2.2H20/Al(NO3)3.9H20) The doping amount of the zinc oxide film is too high, the thickness of the zinc oxide film is gradually increased, the volume of the hollow glass beads is gradually increased, the specific surface area is reduced, the infrared reflectivity is reduced, and finally the heat preservation effect of the fabric is reduced.
(3) As can be seen by combining examples 7-9 with tables 2 and 3, when Zn (CH) is added3C0O)2.2H20 and Al (NO)3)3.9H2When the molar ratio of 0 is 20 (3-5), the prepared heating and warm-keeping fabric has good heat preservation performance. The reason may be that the aluminum doping amount in the oxide film is too low, and the infrared reflectivity of the oxide film is affected; when Al (NO)3)3.9H2The 0 doping amount is too high, and the excessive aluminum causes the lattice defect area of the oxide film to be too large, so that the reflectivity of infrared rays is reduced, and the heat preservation effect of the fabric is reduced.
(4) In example 10, when the aluminum-doped zinc oxide/hollow glass bead composite powder is prepared, hydroxypropyl cellulose is not added, and the heat retention performance of the prepared fabric is reduced to some extent. The reason for this may be that the non-addition of hydroxypropyl cellulose causes the decrease in wettability and the uneven dispersion of the hollow glass beads, and the decrease in the density of an oxide film formed on the surface thereof causes the decrease in infrared reflectance, and finally causes the decrease in the heat retention effect of the fabric.
(5) By combining examples 11-12 and examples 13-15 with Table 2, it can be seen that the thermal insulation performance of the fabric can be effectively improved by using the carboxymethyl cellulose and the nonionic polyacrylamide as the film forming auxiliary agent. The carboxymethyl cellulose can fully wet the aluminum-doped zinc oxide/hollow glass bead composite powder, the nonionic polyacrylamide can reduce the flow resistance among particles of the composite powder, and the carboxymethyl cellulose and the nonionic polyacrylamide are matched to improve the dispersibility of the aluminum-doped zinc oxide/hollow glass bead composite powder, so that the load rate of the aluminum-doped zinc oxide/hollow glass bead composite powder on the fabric is improved, and the heat preservation effect of the fabric is improved.
Test 3: water resistance test of heating and warming knitted fabric
Test samples: the heat-generating and warm-keeping knitted fabrics prepared in examples 11 to 18.
The test method comprises the following steps: after soaking the sample in water at 2 ℃ for 30 days, the sample was dried under 50 ℃ under a hot base condition, and then the heat retention rate of the test was measured according to the test method in test 1, and the test results are shown in table 4.
Table 4 test results of water resistance of the heating warm-keeping knitted fabrics in examples 11 to 18
(1) By combining examples 11-12 and examples 13-14 with Table 4, it can be seen that the use of carboxymethyl cellulose and nonionic polyacrylamide is beneficial to improving the water resistance of the heat-generating warm-keeping knitted fabric, and the combination effect of the carboxymethyl cellulose and the nonionic polyacrylamide is better. The reason for the coating is probably that the film-forming assistant obtained by mixing the carboxymethyl cellulose and the nonionic polyacrylamide is beneficial to forming a uniform and compact coating on the fabric by the heating and warm-keeping coating, so that the porosity of the coating is reduced, water molecules are not easy to permeate the coating, the coating is damaged, the far infrared master batches are not easy to fall off, and finally the water resistance of the heating and warm-keeping knitted fabric is improved
(2) By combining examples 11-12 and examples 15-14 with Table 4, it can be seen that the use of isocyanate and defoamer is beneficial to improving the water resistance of the heat-generating warm-keeping knitted fabric, and the combination effect of the isocyanate and the defoamer is better. The reason for this is probably that the polyisocyanate can be crosslinked with the polyvinyl alcohol, and the defoaming agent can eliminate the carbon dioxide gas generated by the reaction of the polyisocyanate in water, which is beneficial to improving the compactness of the heating and warm-keeping coating and improving the water resistance of the heating and warm-keeping knitting.
