Embodiment 1

[0025] The surface impurities of the silk fiber are removed and activated, and then soaked in 12% sodium carbonate weak alkaline solution to swell. Mixing 38-126nm nano-silica and pentaerythritol ester to prepare a heat-resistant antioxidant, wherein the mass fraction of pentaerythritol ester is 2%, and the mass fraction of nano-silica is 0.1%. Pour the heat-resistant antioxidant into the solution for mixing, vibrate at room temperature, and take out after the silk is completely soaked to obtain pretreated silk.

[0026] After washing the container with deionized water, put the pretreated silk in it and seal it for heating reaction. The initial temperature is 25°C, and the temperature is raised to 60°C at a rate of 1°C / min. After 2 hours of heat preservation, the temperature is naturally cooled to room temperature and cooled. Finally, take the silk out of the container, dry it completely at 60°C, wash it with water at 20°C once, remove the loosely bonded substances on the surf...

Embodiment 2

[0028] The surface impurities of the silk fabric are removed and activated, soaked in 12% sodium bicarbonate weak alkaline solution to swell. Mixing 38-126nm nano-silica and pentaerythritol ester to prepare a heat-resistant antioxidant, wherein the mass fraction of pentaerythritol ester is 3%, and the mass fraction of nano-silica is 0.5%. Pour the heat-resistant antioxidant into the solution for mixing, vibrate at room temperature, and take out after the silk is completely soaked to obtain pretreated silk.

[0029] After washing the container with distilled water, put the pretreated silk in it to seal and heat the reaction. The initial temperature is 25°C, and the temperature is raised to 70°C at a rate of 2°C / min. After 3 hours of heat preservation, the temperature is naturally cooled to room temperature. Take the silk out of the container, dry it completely at 60°C, wash it twice with water at 30°C, remove the loosely bonded substances on the surface, and dry it naturally to...

Embodiment 3

[0031] The surface impurities of the silk fiber are removed and activated, soaked in 12% sodium bicarbonate weak alkaline solution to swell. Mixing 38-126nm nano-silica and pentaerythritol ester to prepare a heat-resistant antioxidant, wherein the mass fraction of pentaerythritol ester is 2.5%, and the mass fraction of nano-silica is 0.3%. Pour the heat-resistant antioxidant into the solution for mixing, vibrate at room temperature, and take out after the silk is completely soaked to obtain pretreated silk.

[0032] After washing the container with deionized water, put the pretreated silk in it and seal it for heating reaction. The initial temperature is 25°C, and the temperature is raised to 65°C at a rate of 1.5°C / min. After 2.5 hours of heat preservation, the temperature is naturally cooled to room temperature After cooling, take the silk out of the container, dry it completely at 60°C, wash it once with water at 25°C, remove the loosely bonded substances on the surface, an...

Abstract

The invention discloses special high-temperature-resisting silk and a preparation method thereof. The method comprises the following steps: removing impurities from the surface of raw silk, activating, and soaking in a weak alkaline solution for swelling; mixing with a heat resisting antioxidant; oscillating at room temperature; taking out after the silk is completely wetted, putting into a container and sealing; heating and reacting; naturally cooling; finally taking out the treated silk from the container and drying completely; washing by water to remove substances which are not tightly combined with the surface; and drying to obtain the special high-temperature-resisting silk. The method is used for simply preparing the special high-temperature-resisting silk by utilizing swelling and hydrothermal reaction, and the prepared silk is obviously improved in high temperature resistance in comparison with untreated silk.

Description

Technical field: [0001] The invention belongs to the technical field of silk products, in particular to a method for preparing high temperature-resistant special silk Background technique: [0002] As we all know, silk is one of the materials with the best wearing comfort among clothing fibers. Its good thermal conductivity (about 0.055W / m*℃) and porous structure in the structure make silk fabrics have good moisture absorption, moisture release, and air retention. The ability of breathability can spontaneously adjust the airflow and humidity of the skin surface, making the user feel comfortable, warm in winter and cool in summer, and the heat resistance of silk is good. When heated above 100 ℃, a large amount of water will be lost, and the strength will be reduced. , Silk will begin to decompose and carbonize when heated above 150°C. Therefore, the heat resistance and warmth retention of silk itself are better, which can meet the needs of daily civilian use, but its applica...
