Problems solved by technology

The advantage of using resin anti-wrinkle is that the effect is more obvious, but because the treatment liquid contains harmful substances such as formaldehyde, it is not conducive to environmental protection; at the same time, the durability is not strong, etc.
Therefore, many successful anti-wrinkle processes can no longer be used as people pay more and more attention to environmental protection issues.

Embodiment 1

[0016] Embodiment 1: Improvement of pressing performance

[0017] Select two woolen fabric samples, about 70 grams each, bath ratio 1:15, enzyme concentration 2.5% (o.w.f.). First, the two cloth samples are pretreated with distilled aqueous solution at 43 degrees Celsius (time 30 minutes), and then respectively in The enzyme solution at 50 degrees centigrade and the water at 50 degrees centigrade were each treated for 1 hour, then washed with tap water and dried in the air. Cut fabric samples with a specification of 40*20mm, and iron them with an iron at 100 degrees Celsius for 3.5 minutes (without getting wet). After different recovery times, the changes in their pressing angles are measured in Table 1:

[0018] Experiment number

[0019] It can be seen from the data that the pressing angle of the enzyme-treated fabric is significantly smaller than that of the untreated fabric. After 3.5 minutes of recovery, the reduction rate reaches 26.4%; after 1 hour of recovery...

Embodiment 2

[0020] Example 2: Improvement of Dimensional Stability

[0021] There are 3 pieces of cut fabric samples, the size is similar, and the weight of the fabric samples is about 22.5 grams. The quality of finished enzyme 1, finished enzyme 2 is all got 0.75 gram, aqueous solution 450ml, bath ratio 1: 20, 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 sufficient reaction. The numbers of the treated samples are 1, 2, and 3, corresponding to finished enzyme 1 treatment, finished enzyme 2 treatment and blank samples.

[0022] Before enzymatic treatment, iron the three fabrics flat, and mark the stitches of L1 (100mm) with a ruler. After the treatment, put the fabric in the washing machine for washing, rinsing, drying, and drying, then iron the fabric, measure the length L2 of the stitches, and calculate the warp shrinkage aj. The test data are shown in T...

Embodiment 3

[0026] Example 3: Improvement of wrinkle resistance

[0027] There are 3 pieces of cut fabric samples, the size is similar, and the weight of the fabric samples is about 22.5 grams. The quality of the finished enzyme 1 and the finished enzyme 2 is 0.75 grams, and the aqueous solution is 450 ml, 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 sufficient reaction. Three samples of the same specification were treated with finished enzyme 1 treatment (No. 1), finished enzyme 2 treatment (No. 2) and blank sample (No. 3).

[0028] The fabric samples were washed properly, hung, and several uninformed professionals were invited to evaluate the wrinkle condition. The results agreed that No. 1 was the best in terms of wrinkle resistance of wool fabrics, followed by No. 2. The No. 3 enzyme is the worst, indicating that the wrinkle resistance of the enzyme-tr...

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...
