Embodiment 1
[0052] First soak the wool fabric in the 50°C treatment solution (JFC penetrant 1g / L) for 30s, and pass through the padding machine once; / L, Savinase 16L 1.3g / L, 50°C, bath ratio 1:100) soaked for 30s, passed through a rolling mill once (time 10s, liquid carrying rate 85%). Continuous immersion and liquid squeezing for 5 times, the error range of the control liquid carrying rate is within 1%. Immediately after continuous padding, soak the fabric in hot water at 80°C for 10 minutes to inactivate protease, then wash it in cold water for 10 minutes, and then dry it in an oven at 100°C to obtain enzyme-treated woolen fabric for later use.
[0053] The breaking strength of the fabric after enzyme treatment is tested; the breaking strength of the fabric is operated according to the method described in GB / T3923.1-2003 "Tensile Properties of Textile Fabrics Part One Determination of Breaking Strength and Elongation at Break" . The test fabric is a cloth strip with a length of 30 cm...
Embodiment 2
[0059] First soak the wool fabric in the 50°C pretreatment solution (JFC penetrant 1g / L) for 30s, and pass through the padding machine once; / L, Savinase 16L 1.3g / L, 50°C, bath ratio 1:100) for 200s; soak the soaked fabric in 80°C hot water for 10 minutes to inactivate protease, then wash in cold water for 10 minutes, and wash thoroughly Put it into an oven for drying at 100° C. to obtain the wool fabric after enzyme treatment.
[0060] This enzyme treatment method can also improve the inkjet printing effect of wool fabrics, but the final effect is not as good as that of continuous padding.
Embodiment 3
[0066] Prepare 2wt% sodium alginate printing paste: First, dissolve 10g of urea and 2g of ammonium sulfate in 86g of distilled water under the action of mechanical stirring, stir with a stirrer RW20 at a speed of 1000r / min, and then slowly mix 2g of sodium alginate Pour into the dissolved solution to obtain the sodium alginate printing paste with a pH value of 5.6-6.6 and a viscosity of 1000-2000mPa·s.
[0067] Use the P-B0 horizontal padding machine to pad the prepared printing paste onto the wool fabrics obtained in Example 1 and Comparative Examples 1-2 respectively, and the pressure on both sides of the roll is 0.1kg / cm 2 , The roll speed is 12r / min, and the liquid carrying rate of the fabric is (80±1)%. The padded fabrics were dried in an oven at 80° C. to obtain modified wool fabrics respectively.
