adding distilled water into beta-cyclodextrin to prepare saturated solution, adding AlCl3Mixing, stirring at 60-70 deg.C for 30-40min, standing, vacuum filtering, washing with ethanol solution, and oven drying to obtain clathrate A (coated with Al)3+Beta-cyclodextrin of (a); mixing the melamine phosphate solution with the inclusion compound A, and performing ultrasonic dispersion for 10-20min to obtain a flame retardant solution;
the melamine phosphate solution is a nitrogen-phosphorus synergistic flame retardant, is a commonly used high-efficiency flame retardant in the existing textile technology, and has the characteristics of low smoke toxicity, no halogen element, good durability and good flame retardant effect; but the compatibility of the melamine phosphate solution and the non-woven fabric interface is not ideal, and the electrical property is poor due to easy moisture absorption; the flame retardant property is not fully exerted, the flame retardant effect is not ideal, and the phenomenon of dropping of the melt is easy to generate. In the technical scheme, AlCl is treated by beta-cyclodextrin3When the beta-cyclodextrin is introduced into a system, the inner cavity space of beta-cyclodextrin molecules is large and hydrophobic, so that the moisture absorption phenomenon is avoided, and the beta-cyclodextrin has solubilization property and good compatibility with a non-woven fabric substrate. AlCl3Middle Al3+Synergize with the P = O bond on melamine phosphate; the thermal stability of the melamine phosphate is enhanced, more coke is generated by cracking the catalytic viscose during combustion, a carbonized covering layer is formed on the non-woven fabric base layer, external oxygen is prevented from entering and heat is prevented from being dissipated, and meanwhile, the generation of combustible gas is inhibited; the flame retardancy of the non-woven fabric is improved.
(2) The modified viscose fiber is prepared by the following steps:
adding viscose fiber spinning solution into the flame retardant solution; magnetically stirring for 30min at the stirring speed of 180-; vacuum defoaming the blended solution at 27-32 deg.C for 40-45min to obtain modified viscose spinning solution;
contacting the modified viscose spinning solution with a coagulant in a coagulating bath, and outputting through a spinning hole to form nascent fiber; drafting the nascent fiber; neutralizing and washing with water; obtaining the modified viscose fiber.
(3) Preparing a non-woven fabric base layer by the following steps:
s1, opening and mixing modified viscose fibers, polyester fibers and polypropylene fibers;
s2, carding to remove impurities, stacking and paving into a fiber net, wherein the number of layers of the fiber net is 8-10;
s3, needling and consolidating the fiber web from top to bottom; sequentially carrying out one-time pre-needling, three-time main needling, high-temperature hot rolling and winding; wherein the needling frequency of the pre-needling is 600 needling/min, and the needle depth is 12 mm; the frequency of the first main needling is 750 needling/min, and the depth of the needles is 10 mm; the frequency of the second main needling is 750 needling/min, and the depth of the needles is 8 mm; the frequency of the third main needling is 750 needling/min, and the depth of the needles is 5 mm; high-temperature hot rolling, wherein the hot rolling temperature is 220-225 ℃; winding in a crimping machine; preparing a needle punched non-woven fabric;
s4, enabling the needled non-woven fabric to pass through the prepared flame retardant solution at a constant speed of 7-9m/min, and enabling the needled non-woven fabric to be fully soaked in the flame retardant solution; the needle-punched non-woven fabric soaked by the flame retardant solution is sequentially rolled by double rollers at the speed of 7-9m/min and the rolling drying force is 3-6 kg; tentering; drying at 145-150 deg.c and pressing the surface to obtain the non-woven fabric base layer.
Polypropylene fiber and polyester fiber belong to intrinsic flame-retardant fibers; the modified viscose fiber has flame retardant property after being treated by the flame retardant solution; the three fibers are blended, and the non-woven fabric produced by needling is soaked in a flame retardant solution, so that the non-woven fabric has a good flame retardant effect.
(4) The method for preparing the water washing resistant layer and the flame retardant layer comprises the following steps:
s1, a water-washing resistant layer: adding epoxy acrylate, butyl acrylate and dodecyl alcohol ester into deionized water according to the mass ratio of 5:1:0.1, and stirring for 10-15min to obtain a mixed solution A;
mixing beta-cyclodextrin and glycidyl methacrylate in a mass ratio of 1:2, adding the mixture into a dimethylacetamide solvent, adding hydroquinone, and reacting for 6 hours at the temperature of 57-62 ℃; naturally cooling; adding acetone solution into the mixture to react to generate white fixed powder; filtering the white precipitate, and washing with acetone solution; vacuum drying to obtain clathrate B;
placing the non-woven fabric base layer into the mixed solution A, and soaking for 40-60 min; adding the inclusion compound B, and mixing the inclusion compound B with the mixed solution A; soaking photoinitiator 1173 (2-hydroxy-2-methyl-1-phenyl acetone) in a photoinitiator at 37-40 deg.C for 6-8 h; vacuum drying to form a water washing resistant layer;
because the epoxy acrylate is an excellent epoxy resin and has excellent water resistance, hot water resistance, drug resistance, cohesiveness and toughness, the protective film with strong water resistance can be formed by soaking the non-woven fabric base layer with the epoxy acrylate; but the epoxy acrylate is extremely viscous and has no fluidity at normal temperature, butyl acrylate is added as an active diluent to dilute and reduce the viscosity of the epoxy acrylate and the crosslinking density of a film of the epoxy acrylate, so that the gel degree of the epoxy acrylate is reduced; so that the non-woven fabric base layer forms a better epoxy acrylate film. Introducing glycidyl methacrylate into beta-cyclodextrin molecules to form beta-cyclodextrin supramolecules including vinyl groups; the beta-cyclodextrin supermolecule is grafted to a crosslinking system of epoxy acrylate, butyl acrylate and dodecyl alcohol ester through a photoinitiator, and vinyl and the epoxy acrylate are copolymerized, so that the breaking elongation of the film is increased, and the toughness of the film is improved; the self-repairing function of the epoxy acrylate film is improved, and when the surface layer is scraped by external force, the film can complete self-repairing without generating cracks. Therefore, the epoxy acrylate, the butyl acrylate, the beta-cyclodextrin and the glycidyl methacrylate act together to form the washable layer, and the washable layer has a good self-repairing function.
