Embodiment

[0013] The non-iron finishing process of real silk in this embodiment adopts chemical methods, and uses a formaldehyde-free non-ironing finishing agent to finish the silk. The specific steps are as follows: (1) Preparation of finishing solution: put glycerol into a three-necked bottle and vacuumize Remove water, then add catalyst boron trifluoride ether and additive epichlorohydrin, keep warm at 50°C for 35 hours, continue to add ring-closing catalyst, special mixed solvent, and control the temperature at 40°C, and finally add sodium hydroxide And keep warm for 1 hour to discharge the material, and obtain the finishing solution after vacuum filtration and atmospheric distillation. The finishing solution: the epoxy value is O. 45. Residual organic chlorine 0.38%, PH value: 7.2; (2) Add penetrating agent to the finishing solution, then immerse the silk and roll it evenly with a paddle; (3) Soak the finished silk in the catalyst solution After 2 minutes, roll it evenly with a rol...

Abstract

The invention discloses a silk broadcloth non-iron finish process. The method for preparing finishing liquid comprises the following steps: adding glycerol into a three-necked bottle, and vacuumizing to remove the water; adding a catalyst boron trifluoride diethyl etherate and an additive epoxy chloropropane, and preserving the temperature under the temperature condition of 50-55 DEG C for 30-40 hours; continuously adding a closed-loop catalyst and a special mixed solvent, controlling the temperature to be 40-45 DEG C, and finally, adding sodium hydroxide, preserving the temperature for an hour, discharging, performing vacuum filtration and atmospheric distillation, thereby obtaining the product, wherein the catalyst boron trifluoride diethyl etherate, the additive epoxy chloropropane and the sodium hydroxide are added under anhydrous conditions. The obtained finishing liquid has high purity; the chlorine content is effectively controlled by virtue of vacuum filtration; according to the treatment process, a large wet wrinkle recovery angle is obtained by adopting a two-bath method of separate dry and wet treatment; and the finished silk broadcloth is good in handfeel, and the style of the silk broadcloth can be well maintained.

Description

[0001] technical field [0002] The invention belongs to the technical field of silk functional treatment, and in particular relates to a non-ironing finishing process of real silk. [0003] Background technique [0004] Real silk is composed of protein fibers, which has excellent biocompatibility with the human body. In addition, its surface is smooth, and its frictional stimulation coefficient to the human body is the lowest among all kinds of fibers, so it is loved by people. With the continuous improvement of people's living standards, the performance requirements of silk are getting higher and higher, such as wrinkle resistance. The finished silk has good wrinkle resistance, but the overall performance cannot meet people's requirements. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems existing in the prior art, the object of the present invention is to provide a non-ironing finishing process for real silk, so t...
