Embodiment 1

[0034] A preparation method of a novel modified silicone softening agent, comprising the following steps:

[0035] Step 1: Preparation of Catalyst:

[0036] Add 2g of zinc sulfate and 2g of D-sodium D-gluconate solid into 100ml of water, stir evenly, and treat in an ultrasonic oscillator in a water bath at 40°C for 10 minutes to prepare a catalyst solution;

[0037] The second step: preparation of modified silicone softener:

[0038] According to the molar ratio of 1:3:2, polysiloxane, butyl methacrylate, and n-butyl acrylate were mixed and stirred for 1 hour, and then the temperature was raised to 50°C. After the temperature was raised, a catalyst solution with a mixing weight of 1% was added, mixed and stirred evenly, and the temperature was raised to 100°C to obtain a modified silicone softener.

Embodiment 2

[0040] A preparation method of a novel modified silicone softening agent, comprising the following steps:

[0041] Step 1: Preparation of Catalyst:

[0042] Add 2g of zinc sulfate and 4g of D-sodium D-gluconate solid into 100ml of water, stir evenly, and treat in an ultrasonic oscillator in a water bath at 45°C for 15 minutes to prepare a catalyst solution;

[0043] The second step: preparation of modified silicone softener:

[0044] According to the molar ratio of 1:4:3, polysiloxane, butyl methacrylate, and n-butyl acrylate were mixed and stirred for 2 hours, and then the temperature was raised to 60°C. After the temperature was raised, a catalyst solution with a mixing weight of 1.5% was added, mixed and stirred evenly, and the temperature was raised to 120°C to obtain a modified silicone softener.

Embodiment 3

[0046] A preparation method of a novel modified silicone softening agent, comprising the following steps:

[0047] Step 1: Preparation of Catalyst:

[0048] Add 2g of zinc sulfate and 3g of D-sodium gluconate solid into 100ml of water, stir evenly, and treat in an ultrasonic oscillator in a water bath at 45°C for 10 minutes to prepare a catalyst solution;

[0049] The second step: preparation of modified silicone softener:

[0050] According to the molar ratio of 1:4:2, polysiloxane, butyl methacrylate, and n-butyl acrylate were mixed and stirred for 2 hours, and then the temperature was raised to 50°C. After the temperature was raised, a catalyst solution with a mixing weight of 1.5% was added, mixed and stirred evenly, and the temperature was raised to 100°C to obtain a modified silicone softener.

Abstract

The invention discloses a preparation method and application of a novel modified organic silicon softening agent, and belongs to the technical field of textile chemical industry. The preparation method comprises the catalyst preparing process and the softening agent preparing process, wherein zinc sulfate and D-sodium gluconate solids are added into 100 ml of water to be mixed to prepare a catalyst solution, polysiloxane, butyl methacrylate and n-butyl acrylate are mixed and stirred, the catalyst solution is added after the temperature is increased, and a temperature increasing reaction is performed to obtain the modified organic silicon softening agent. The invention further discloses application of the organic silicon softening agent in a flax fabric finishing technology. The preparation method is simple, convenient, easy to operate, low in cost and suitable for the large-scale industrialized production requirement; after the novel modified organic silicon softening agent is applied to flax fabric finishing, the good flexibility and wrinkle resistance are given to flax fabric fiber, the smoothness and brightness are also excellent, and the extremely high market promotion value is achieved.

Description

Technical field: [0001] The invention discloses a preparation method of a novel modified silicone softener and applies it to the finishing process of linen fabrics, belonging to the technical field of textile chemical industry. Background technique: [0002] Linen fabric belongs to natural cellulose fiber and is the main raw material of linen fabric. It is known as "Fiber Queen". Linen textiles have fast moisture absorption and moisture dissipation, good air permeability, and wearing properties such as crispness. At the same time, due to the nature of the fiber itself, it also has natural excellent hygiene, antibacterial and anti-mildew effects, and good antistatic and anti-ultraviolet properties. In the wave of advocating clothing to return to nature, these advantages undoubtedly make linen textiles the focus of attention. However, the crystallinity and orientation of flax fibers are high, and the macromolecules are arranged neatly and tightly, resulting in small elongatio...
