[0020] A preparation method for modified sisal carpet, comprising the following steps:
[0021] a. Immerse the sisal carpet in a sodium hydroxide solution with a concentration of 8-10%, cook it at 75-85°C for 3-5h, filter it out and dehydrate it at 600-800r / min for 1-2min to obtain the infiltrated sisal carpet ;
[0022] b. Put the impregnated sisal carpet into the autoclave, spray the additives of 1‰-2‰ relative to the weight of the sisal carpet into the autoclave, and preheat at 80-100r / min under the saturated steam pressure of 0.6-0.8MPa. Heat for 10-15min to obtain pretreated sisal carpet;
[0023] c. Add metasilicic acid, coupling agent and antioxidant with relative sisal carpet weight ratio of 100: (3-5): (1-3): (1-3) to the pretreated sisal carpet, at 50 Mix at -60°C at 300-500r / min for 5-8min, heat up to 165-180°C for 40-60min after vacuuming, and cool naturally to obtain a modified sisal carpet;
[0024] d. Rinse the modified sisal carpet with a high-pressure water...

[0032] A preparation method for modified sisal carpet, comprising the following steps:
[0033] a. Immerse the sisal carpet in a sodium hydroxide solution with a concentration of 10%, cook it at 75°C for 5 hours, filter it out and dehydrate it at 600r / min for 2min to obtain the infiltrated sisal carpet;
[0034] b. Put the soaked sisal carpet into the autoclave, spray the pulping penetrant of 1‰ relative to the weight of the sisal carpet into the autoclave, and preheat it at 80r / min for 10min under the saturated vapor pressure of 0.8MPa to obtain Pretreatment of sisal carpets;
[0035]c. Add metasilicic acid, water-based silane coupling agent and antioxidant 264 to the pretreated sisal carpet at a weight ratio of 100:3:3:1, and mix at 50°C for 8 minutes , heat up to 165°C for 60 minutes after vacuuming, and cool naturally to obtain a modified sisal carpet;
[0036] d. Rinse the modified sisal carpet with a high-pressure water gun, soak it in saturated salt water for 30 minut...

[0038] A preparation method for modified sisal carpet, comprising the following steps:
[0039] a. Immerse the sisal carpet in a sodium hydroxide solution with a concentration of 8%, cook it at 85°C for 3 hours, filter it out and dehydrate it at 800r / min for 1min to obtain the infiltrated sisal carpet;
[0040] b. Put the soaked sisal carpet into the autoclave, spray 2‰ of ML penetrating softener relative to the weight of the sisal carpet into the autoclave, and preheat at 100r / min for 15min under the saturated steam pressure of 0.6MPa to obtain the preheated Treatment of sisal carpets;
[0041] c. Add metasilicic acid, coupling agent and antioxidant 1010 with a weight ratio of 100:5:1:3 to the pretreated sisal carpet, and add textile dyes with a weight of 5‰ relative to the sisal carpet, Mix at 300r / min at 60°C for 5min, heat up to 180°C for 40min after vacuuming, and cool naturally to obtain a modified sisal carpet;
[0042] d. Rinse the modified sisal carpet with a high-p...
