Embodiment 1
[0030] (1) configure 10g / L hydroxylamine hydrochloride aqueous solution, use 5M sodium hydroxide solution to adjust the pH value of hydroxylamine hydrochloride solution to be 8 to obtain hydroxylamine solution;
[0031] (2) Put the wool woven fabric in a hydroxylamine solution with a pH value of 8 (bath ratio 1:10), add 2g / L Tween-80, and shake at a constant temperature of 50°C in a shaking water bath for 3 hours, Wash again, dry;
[0032] (3) configure 8g / L L-cysteine aqueous solution, use ammonia water to adjust the pH value to 8;
[0033] (4) Put the hydroxylamine-treated wool in an L-cysteine solution with a pH value of 8 (bath ratio 1:30), place it in a oscillating water bath at a constant temperature of 50°C for 3 hours, then wash it with water and dry it. dry to obtain wool fibers with high surface reactivity;
[0034] Use contact angle tester, fabric antistatic instrument and electronic single fiber strength tester to test the water drop spreading time, antistati...
Embodiment 2
[0038] (1) configure 12g / L hydroxylamine hydrochloride aqueous solution, use 5M sodium hydroxide solution to regulate hydroxylamine hydrochloride solution pH to get hydroxylamine solution after being 8 values;
[0039] (2) Put the wool woven fabric in a hydroxylamine solution with a pH value of 8 (bath ratio 1:10), add 2 g / L Tween-80, and place it in a oscillating water bath for 3 hours at a constant temperature of 50°C. Wash again, dry;
[0040](3) configure 10g / L L-cysteine aqueous solution, use ammonia water to adjust the pH value to 8;
[0041] (4) Put the hydroxylamine-treated wool in an L-cysteine solution with a pH value of 8 (bath ratio 1:30), place it in a oscillating water bath at a constant temperature of 50°C for 3 hours, then wash it with water and dry it. dry to obtain wool fibers with high surface reactivity;
[0042] (5) In the dye bath containing 2% owf formic acid, 5% owf sodium sulfate, 1% owf nonionic surfactant and 6% owf Anofix C-BS (reactive dyes f...
Embodiment 3
[0054] (1) prepare high surface reactivity wool fiber according to the modification method of embodiment 2;
[0055] (2) In the dyeing bath containing 2% owf acetic acid, 5% owf sodium sulfate, 1% owf additive (nonionic surfactant) and 2% owf weak acid brilliant red B dye (weak acid acid dye), the modified The non-modified and unmodified wool fabrics were dyed at room temperature and heated up to 60°C at a rate of 1°C / min, kept for 60min, washed and dried.
[0056] The color strength (K / S) of the dyed wool fabric was evaluated with a Datacolor 650 reflection spectrophotometer (Datacolor, USA). Calculate K / S value according to Kubelka-Munk theory:
[0057] where R is the reflectivity.
[0058] Use UV-1800PC spectrophotometer (Mapada, Shanghai), measure the dye uptake (E%) of acid dye according to the following equation:
[0059]
[0060] where A 1 and A 2 are the absorbance of the solution at the maximum wavelength at the beginning of staining and at the end of staini...
