Example Embodiment

[0016] Example 1: Improvement of pressing performance

[0017] Select two wool fabric samples, each about 70 grams, with a bath ratio of 1:15, and an enzyme concentration of 2.5% (owf). The enzyme solution at 50 degrees Celsius and the water at 50 degrees Celsius were treated for 1 hour each, and then washed with tap water and dried. Cut cloth samples with a size of 40*20mm, iron them for 3.5 minutes with an iron at 100 degrees Celsius (not wet), after different recovery times, measure the changes in their pressing angles, see Table 1:

[0018] Experiment number

[0019] It can be seen from the data that the press angle of the enzyme-treated fabric is significantly smaller than that of the untreated fabric. After 3.5 minutes of recovery, the reduction is 26.4%; after 1 hour of recovery, the reduction is 9.3%. It also shows that after the enzyme treatment, the ironing performance of the wool fabric has been significantly improved.

Example Embodiment

[0020] Example 2: Improvement of dimensional stability

[0021] Cut 3 pieces of cloth samples, similar in size, the weight of the cloth samples is about 22.5 grams. The quality of the finished enzyme 1 and the finished enzyme 2 are both 0.75 grams, 450 ml of aqueous solution, bath ratio 1:20, and the concentration is 3.3% (o.w.f.). Without pretreatment, soak the fabric in the corresponding solution for 90 minutes, and the test temperature is still 50 degrees Celsius to ensure a sufficient response. The processed sample cloth numbers are 1, 2, and 3, corresponding to finished enzyme 1 treatment, finished enzyme 2 treatment and blank samples.

[0022] Before the enzyme treatment, iron the three pieces of fabric flat, and mark the L1 (100mm) stitch with a ruler. After treatment, put the fabric in a washing machine for washing, rinsing, spin-drying, and drying, then iron the fabric, measure the stitch length L2, calculate the warp shrinkage aj, the test data is shown in Table 2. :

[0026] Example 3: Improvement of wrinkle resistance

[0027] Cut 3 pieces of cloth samples, similar in size, the weight of the cloth samples is about 22.5 grams. The quality of the finished enzyme 1 and the finished enzyme 2 is 0.75 grams, 450 ml of the aqueous solution, and the concentration is 3.3% (o.w.f.). Without pretreatment, the fabric is soaked in the solution for 90 minutes, and the test temperature is still 50 degrees Celsius to ensure a sufficient response. Three samples of the same specifications were treated with the finished enzyme 1 treatment (No. 1), the finished enzyme 2 treatment (No. 2) and the blank sample (No. 3).

[0028] After the cloth sample was washed and hung in a proper washing process, several unknowing professionals were asked to evaluate the wrinkle situation. The results were unanimously agreed that in terms of wrinkle resistance of wool fabrics, No. 1 is the best, No. 2 is the second, and not used. Enzyme No. 3 is the worst, indicating that the wri...

Abstract

The invention is a method for using glutamine transaminage to process wool textile. The glutamine transaminage is dissolved in water to produce the enzyme processing liquid, then the wool textile is put into the liquid to be processed, the invention enhances the association effect of wool protein fiber, realizes the effect of easy nursing. At the same time, the invention uses MTG enzyme process, the invention accords with the demands of environment protection, it has no contamination.

Description

technical field [0001] A method for treating wool fabrics with transglutaminase, relating to the use of transglutaminase for protein fibers, especially wool fibers; and to the treatment of wool fabrics. technical background [0002] At present, there are many methods for easy care of wool fabrics, such as chemical methods such as chlorination of wool, physical methods such as plasma surface treatment, in order to overcome the difficult care of wool fibers. However, the environmental protection problems brought by chemical methods and the limitations of plasma treatment are waiting for people to find more ecological and effective methods. To make wool fabric easy to care, the evaluation of easy care mainly includes the following aspects: felting shrinkage, dimensional stability, pressing property and wrinkle resistance. There are many studies on shrink-proof wool fabrics at home and abroad. There is a process for treating wool with protease in foreign countries. This proces...
