Embodiment 1

[0017] Chitosan is modified by atom transfer radical technology to obtain chitosan derivative chitosan methacrylate with an average molecular weight of 38000Da and a particle size of 120-180nm, and chitosan methacrylate is made into a concentration A 60% solution of modified chitosan derivatives. After removing surface impurities and activating the surface of the silk fabric, soaking in the modified chitosan derivative solution for 10 minutes, taking out the water, washing and drying to obtain the pretreated silk fabric.

[0018] Microwave the pretreated silk fabric for 10 minutes at a power of 500W to polymerize the chitosan derivatives on the surface of the silk. After reaching an average degree of polymerization of 12, wash with ethanol, wash with water, dry at 50°C, and dry at 150°C. Dry down for 3 seconds to obtain a flame-retardant silk fabric.

Embodiment 2

[0020] Chitosan is modified by atom transfer radical technology to obtain chitosan derivative chitosan methacrylate with an average molecular weight of 38000Da and a particle size of 120-180nm, and chitosan methacrylate is made into a concentration A 70% solution of modified chitosan derivatives. After removing surface impurities and activating the surface of the silk fabric, soaking in the modified chitosan derivative solution for 20 minutes, taking out the water, washing and drying to obtain the pretreated silk fabric.

[0021] Microwave the pretreated silk fabric for 5 minutes at a power of 600W to polymerize the chitosan derivatives on the surface of the silk. After reaching an average degree of polymerization of 17, wash with ethanol, wash with water, dry at 60°C, and dry at 150°C. Dry down for 5 seconds to obtain a flame retardant silk fabric.

Embodiment 3

[0023] Chitosan is modified by atom transfer radical technology to obtain chitosan derivative chitosan methacrylate with an average molecular weight of 38000Da and a particle size of 120-180nm, and chitosan methacrylate is made into a concentration A 65% solution of a modified chitosan derivative. After removing surface impurities and surface activation of the silk fabric, soaking in the modified chitosan derivative solution for 15 minutes, taking out the water, washing and drying to obtain the pretreated silk fabric.

[0024] Microwave the pretreated silk fabric for 8 minutes at a power of 550W to polymerize chitosan derivatives on the surface of the silk. After reaching an average degree of polymerization of 12-17, wash with ethanol, wash with water, and dry at 55°C. Dry setting at 150°C for 4s to obtain a flame-retardant silk fabric.

Abstract

The invention discloses a method for preparing an environment-friendly flame-retardant silk fabric. The method comprises the following steps: removing surface impurities from the silk fabric, activating the surface of the silk fabric, soaking the silk fabric in a modified chitosan derivative solution, taking out the silk fabric, washing and drying to obtain pre-treated silk fabric, carrying out microwave treatment on the pre-treated silk fabric to generate a polymerization reaction on a chitosan derivative, washing the silk fabric with ethanol, washing the silk fabric with water and drying, and carrying out horizontal drawing and tentering to obtain the flame-retardant silk fabric. According to the method disclosed by the invention, the chitosan derivative is used as a flame retardant, and the grafting technology is combined with the polymerization technology to automatically form a fire retardancy material on the silk surface, so as to improve the limit oxygen index of the silk fabric. The preparation method is simple, the prepared silk fabric has excellent flame retardant property, the quality is scarcely influenced, and the silk fabric is non-toxic and environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of silk products, and in particular relates to a preparation method of an environment-friendly flame-retardant silk fabric. Background technique: [0002] In our daily life, textile fabrics are widely distributed in various fields, such as clothes, curtains, car decoration fabrics, etc. Statistics show that the number of fires caused by textiles accounts for about 50% of the total annual fires, and most of the textiles are in direct contact with the human body. The burning of textiles will cause burns to human skin and even endanger life. [0003] The thermal denaturation of silk fiber itself is small, relatively heat-resistant, the combustion temperature is 300-400°C, and the limiting oxygen index is about 23-24. It is a non-flammable fiber and has certain flame retardancy. Performance requirements also require flame-retardant finishing of silk fibers to increase the added value of silk products and expan...
