Example Embodiment
[0038] Example one:
[0039] A processing technology of waterproof yarn, refer to the attached figure 1 As shown, including the following steps:
[0040] Step 1: Add 1Kg of degreaser and 500g of caustic soda to 1m 3 In clean water, mix evenly at 500 rpm to obtain degreasing liquid;
[0041] Step 2: Heat the degreasing liquid to 90℃, soak the yarn in the degreasing liquid, and keep it warm for 30 minutes;
[0042] Step 3: Use an acetic acid solution with a concentration of 0.2g / L to neutralize and clean the degreasing yarn for 5 minutes, and then rinse with water for 3 minutes;
[0043] Step 4: Put the yarn into the dyeing vat, and add 55% of the volume of the dyeing vat with clean water, add the leveling agent GS and the dye HFRL Violet to the dyeing vat at a ratio of 1:2 to obtain the dye liquor with the dye HFRL Violet concentration of 5wt%. Dyeing in sequence (① heating up at 1.5℃ / min to 80℃; ② heating up to 135℃ at 1.2℃ / min and keeping it for 40 minutes; ③ directly draining the dy...
Example Embodiment
[0060] Embodiment 6:
[0061] The difference between this embodiment and the fifth embodiment is that the starch of the present application is soaked in 3% hydrogen peroxide for 1 hour to obtain oxidized starch.
Example Embodiment
[0062] Embodiment Seven:
[0063] The difference between this embodiment and the fifth embodiment is only that the cyanuric chloride of the present application is modified with palm-based secondary amine.
[0064] The specific steps are as follows: The first step: 0.1mol cyanuric chloride, 0.5mol anhydrous K 2 CO 3 , 0.25mol palm-based secondary amine was sequentially added to a 250mL three-necked flask, protected by nitrogen, allowed to stand for 0.5h under an ice-water bath, and injected with 200mL of dry THF and dry dioxane [V(THF):V(dioxane)= 1:4], respectively react in an ice-water bath and room temperature for 4 hours, then reflux the reaction, remove the solvent under reduced pressure, wash with water to neutrality, and separate by column chromatography [eluent: V (ethyl acetate): V (petroleum) Ether) = 1:200] to obtain a white solid powder;
[0065] Step 2: Add 0.5mol anhydrous K 2 CO 3 , 50mL 1,6-hexamethylenediamine and 150mL dioxane were added to the white solid powder of...
