Problems solved by technology

[0007] The method of biological enzyme treatment of wool before inkjet printing is green and environment-friendly compared with the traditional chemical method, but it combines hydrogen peroxide oxidation pretreatment, which not only causes certain damage to the strength of the fabric, but also has a long process flow, which is not conducive to large-scale production

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.

Abstract

The invention provides an enzyme treatment method of a wool fabric. The enzyme treatment method comprises the steps that alkaline protease and an activating agent are applied to the wool fabric simultaneously, wherein the activating agent is selected from one or more of tricarboxylic ethyl phosphine, sodium pyrosulfite, sodium hydrogen sulfite and mercaptoethanol, the fabric is treated under an alkaline condition at the temperature of 40-65 DEG C, and protease inactivation is carried out to obtain the wool fabric after enzyme treatment. The invention provides a method for ink-jet printing of the wool fabric. The method comprises the steps that printing paste modification is carried out on the wool fabric obtained through the enzyme treatment method to obtain the modified wool fabric; ink-jet printing is carried out on the modified wool fabric by using reactive dye ink or acidic dye ink, the fabric is steamed after being dried, the fabric is washed with water, and the ink-jet printed fabric is obtained. The wool fabric modified through the enzyme treatment method is subjected to ink-jet printing, so that an obtained ink-jet printing pattern is clearer, the color is brighter, the process flow is short, and the fiber damage is small.

Description

technical field [0001] The invention belongs to the technical field of wool printing, and in particular relates to an enzyme treatment method for wool fabric and a method for inkjet printing of wool fabric. Background technique [0002] Wool fiber is mainly composed of the scale layer outside the fiber, the cortex layer forming the main body of the fiber, and the cell membrane complex as a bridge between cells, which is a natural protein fiber. Wool fabric is woven from wool fiber. It has a rich feel and good warmth retention. It is one of the natural fiber fabrics commonly used in textiles. [0003] For printed fabrics, textile digital inkjet printing is a new printing method, referred to as inkjet printing or digital printing. Inkjet printing is directly sprayed on the fabric, which improves the printing accuracy and realizes small batch, multi-variety, multi-color printing, etc. In the inkjet printing process, ink droplets are ejected by the extrusion force of the inkje...
