Problems solved by technology

Acetic acid is commonly used as an acid agent in the dyeing of protein fibers such as silk and wool with acid dyes, but acetic acid is volatile and the pH of the dye solution fluctuates greatly, which affects the reproducibility of dyeing
The traditional dyeing and flame-retardant finishing of protein fibers such as silk and wool need to be carried out in two baths, that is, dyeing first and then finishing, which takes a long time to process and will cause certain damage to the fibers. The feel and color have a certain negative impact

Embodiment 1

[0024] Dissolve phytic acid in water, then add weak acid dye Everacid Yellow N-3R (acid dye with azo structure), and mix to obtain a dyeing and finishing solution, wherein the amount of acid dye is 2% owf (to the weight of the fabric Percentage), the consumption of phytic acid is 150%owf (percentage to fabric weight). Then immerse the silk power spinning and wool fabrics into the dyeing and finishing solution prepared above, heat to 80°C in a water bath, and keep it warm for 60 minutes, then drain the liquid, wash the above fabrics and dry them to obtain the treated fabrics . Performance tests were performed on treated and untreated fabrics, respectively. Among them, the limiting oxygen index (LOI) of the untreated silk fabric was 22.1%, and the LOI of the untreated wool fabric was 23.6%. Untreated silk and wool fabrics burned completely during the vertical burning test, with a char length of 30 cm. And the LOI of the silk fabric treated by the method of the present inventi...

Embodiment 2

[0026] Dissolve phytic acid in water, then add weak acid dye Everacid Red N-RFL (acid dye with azo structure), and mix well to obtain a dyeing and finishing solution. The amount of acid dye is 2.5% owf, and the amount of phytic acid is 120% owf. Then immerse the silk electric spinning and wool into the dyeing and finishing solution prepared above, heat to 90°C in a water bath, and keep it warm for 50 minutes, then drain the liquid, wash the above fabric and dry it to obtain the treated fabric. Performance tests were performed on treated and untreated fabrics, respectively. Among them, the limiting oxygen index (LOI) of the untreated silk fabric was 22.1%, and the LOI of the untreated wool fabric was 23.6%. Untreated silk and wool fabrics burned completely during the vertical burning test, with a char length of 30 cm. And the LOI of the silk fabric processed by the method of the present invention reaches 30.2%, and the charcoal length is only 10.3cm, which satisfies the requi...

Embodiment 3

[0028] Dissolve phytic acid in water, then add 1:2 type acid complex dye Everset Red M-G (1:2 type acid metal complex dye), and mix to obtain dyeing and finishing solution, wherein the amount of acid complex dye is 5% owf, the dosage of phytic acid is 40% owf. Then immerse the silk electric spinning and wool into the dyeing and finishing solution prepared above, heat to 90°C in a water bath, and keep it warm for 60 minutes, then drain the liquid, wash the above fabric and dry it to obtain the treated fabric.

Abstract

The invention relates to a method of dyeing and finishing protein fibers with phytic acid. The method comprises the following steps of: dissolving phytic acid in water, then adding an acidic dye and uniformly mixing the mixture to obtain a dyeing and finishing processing liquid; and soaking the protein fibers in the dyeing and finishing processing liquid, raising the temperature to 80-98 DEG C and keeping the temperature for 30-90 minutes, wherein the dosage of the phytic acid is 20-200%owf. By taking the phytic acid as an accelerating agent and a flame-retardant finishing agent for dyeing the protein fibers at the same time, the protein fibers treated by the phytic acid not only have a bright color, but also has a good flame-retardant property. The method provided by the invention shortens the wet processing flow of the protein fibers and can guarantee that the flame-retardant protein fibers are environmental-friendly and safe in a using process.

Description

technical field [0001] The invention relates to the technical field of textile printing, dyeing and finishing, in particular to a method for dyeing and finishing protein fibers with phytic acid. Background technique [0002] Natural protein fibers are closely related to people's daily life and are widely used in various fields, among which silk and wool are the most important. Silk is called the "Queen of Fibers" because of its soft luster, comfortable wearing, and soft touch. It is widely used in clothing and high-end interior decoration products, such as bedding, carpets, furniture decoration products, curtains, etc. Wool is widely used in sweaters, suits, carpets, high-temperature protective clothing, aircraft interior decoration materials and other fields because of its good wearing performance, easy dyeing, and difficult to ignite. [0003] At present, fires caused by textiles are increasing all over the world, posing a great threat to the safety of human life and prop...
