Embodiment 1
[0055] Embodiment 1, sodium carboxymethyl cellulose fiber non-woven fabric modification
[0056] Take a non-woven fabric with a certain gram weight, the fabric weight is 500 grams, and then put the non-woven fabric into an aqueous solution of sodium hydroxide with a concentration of 18% for alkalization, let it stand for 1 hour, then take out the fabric and put it into the prepared In the sodium chloroacetate solution (9 kilograms of sodium chloroacetate, 8 kilograms of ethanol, 9 kilograms of sodium hydroxide, 18 kilograms of water), react at 40-60 ℃ for 40-80 minutes, then take out the fabric, wash in ethanol solution, Neutralize and dry. The degree of substitution of sodium carboxymethylcellulose fiber non-woven fabric is controlled by adjusting the reaction temperature and time.
Embodiment 2
[0057] Embodiment 2, a kind of hygroscopic gel transparent mask preparation
[0058] 1) The spunlaced tencel non-woven fabric with a grammage of 39 grams per square meter was modified with sodium carboxymethyl cellulose according to the method in Example 1, and the initial reaction temperature was 40°C for 40 minutes to obtain carboxymethyl cellulose with a substitution degree of 0.25. Sodium methyl cellulose fiber non-woven fabric; the sodium carboxymethyl cellulose fiber non-woven fabric is punched and cut into an area of 480cm 2 , weight is the facial mask cloth of 1.8g, obtains facial mask base cloth; This facial mask base cloth is 34g / g to deionized water liquid absorption, and wet strength is 0.7N / 20mm, and wet thickness is 1.3mm;
[0059] 2) In terms of mass percentage: 99.34% of deionized water, 0.05% of xanthan gum, 0.01% of potassium citrate, and 0.6% of 1,2-hexanediol were used as raw materials to obtain a pH of 6.52 and a viscosity of 5mPa s, the facial mask ess...
Embodiment 3
[0061] Embodiment 3, preparation of a kind of facial film that absorbs moisture and becomes gelatinous transparent
[0062] 1) The spunlaced tencel non-woven fabric with a grammage of 29 grams per square meter was modified with sodium carboxymethyl cellulose according to the method in Example 1, and the reaction starting temperature was 42 ° C for 60 minutes to obtain carboxymethyl cellulose with a substitution degree of 0.35. Sodium methyl cellulose fiber non-woven fabric; the sodium carboxymethyl cellulose fiber non-woven fabric is punched and cut into an area of 480cm 2 , weight is the facial film cloth of 1.4g, obtains facial mask base cloth; This facial mask base cloth is 42g / g to deionized water liquid absorption, and wet strength is 0.5N / 20mm, and wet thickness is 1.5mm;
[0063] 2) In terms of mass percentage: 99.14% deionized water, 0.25% xanthan gum, 0.01% potassium citrate, 0.6% 1,2-hexanediol as raw materials, the prepared pH is 6.63, and the viscosity is 230mPa ...
