Embodiment 1

[0027] Dissolve 4.5g of boron phosphate in 50mL of deionized water at 80°C, stir continuously until the solution is colorless, then add the dissolved mixed solution dropwise to 100mL of industrial silica sol, and react at 80°C for 3h , and finally the fabric is immersed in the prepared doped silica sol for 10 minutes, and is finished by the finishing process of two dipping and two rolling (residue rate 90% to 100%)→pre-baking at 80°C for 3 minutes→baking at 180°C for 3 minutes.

[0028] The fabric used in the present invention is real silk 10m / m electric spinning.

[0029] After testing, the limiting oxygen index of the finished silk fabric is 32.4%, and after 30 times of washing, the limiting oxygen index is 24.2%. in addition. In the fabric vertical burning test, the damaged length of the unfinished silk fabric is 30 cm, and the damaged length of the finished silk fabric is 11.7 cm.

Embodiment 2

[0031] Dissolve 4.5g of boron phosphate, 7.5g of citric acid monohydrate, 6g of tartaric acid, and 6.75g of sodium hypophosphite in 50mL of deionized water at 80°C until the solution is colorless, then add the dissolved mixed solution dropwise to 100mL of industrial Use silica sol, and react at 80°C for 3 hours, and finally immerse the fabric in the prepared doped silica sol for 10 minutes, and use two dipping and two padding (reduction rate 90% to 100%) → 80°C pre-baking 3min → 180°C baking 3min finishing process for finishing.

[0032] The fabric used in the present invention is real silk 10m / m electric spinning.

[0033] After testing, the limiting oxygen index of the finished silk fabric is 31.1%, and after 30 times of washing, the limiting oxygen index is 26.6%. in addition. In the fabric vertical burning test, the damaged length of the unfinished silk fabric is 30 cm, and the damaged length of the finished silk fabric is 12.9 cm.

Embodiment 3

[0035] Dissolve 4.5g of boron phosphate, 7.5g of citric acid monohydrate, 3g of tartaric acid, and 6.75g of sodium hypophosphite in 50mL of deionized water at 80°C until the solution is colorless, then add the dissolved mixed solution dropwise to 100mL of industrial Use silica sol, and react at 80°C for 3 hours, and finally immerse the fabric in the prepared doped silica sol for 10 minutes, and use two dipping and two padding (reduction rate 90% to 100%) → 80°C pre-baking 3min → 180°C baking 3min finishing process for finishing.

[0036] The fabric used in the present invention is real silk 10m / m electric spinning.

[0037] After testing, the limiting oxygen index of the finished silk fabric is 28.9%. After 30 times of washing, the limiting oxygen index is 25.8%. In the fabric vertical burning test, the damaged length of the finished silk fabric is 14.3cm.

Abstract

The invention discloses a finishing method of flame-retardant real silk fabric and an application of the finishing. The method comprises the processes of preparing a finishing liquid, preparing the finishing liquid/silica sol, and finishing the real silk fabric, and application of the method in improving the fire resistance of the real silk fabric. The real silk fabric prepared by the finishing method has certain durability. Reagents adopted by the finishing method all are nontoxic and harmless green products, so that green and environment-friendly preparation processes are ensured. The finishing method is suitable for industrial finishing of the real silk fabric.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry and relates to a new fabric finishing method, in particular to a finishing method of flame-retardant silk fabric and its application. Background technique [0002] The rapid economic development is accompanied by prominent environmental problems. In the 21st century, people pay more and more attention to the environment. Therefore, the textiles that are closely related to everyone's life are the first thing people pay attention to. The environmental problems and hazards caused by fabric burning have also been paid more attention to. These demands have prompted printing and dyeing textile workers to develop flame-retardant textiles with higher standards, more effective, durable and without affecting the feel and comfort of fabrics, which is of great significance to human beings and the living environment. [0003] Real silk is a natural fiber with excellent performance. Compared with cel...
