Problems solved by technology

Among the improved flame retardant finishing agents for wool suit fabrics, oxide sols such as zinc oxide, tin oxide, silica sol, etc. are often used, or traditional halogen-containing flame retardants are used. The scales in the fibers of wool suit fabrics are cracked. The fabrics finished with sol have poor washability, while the fabrics finished with halogen-containing flame retardants are not safe enough, and the adhesion of permanent and semi-permanent finishing agents on the fiber surface is poor
In addition, flame retardant finishing will also significantly reduce the depth of dyeing and affect the strength of the cloth surface.

Embodiment 1

[0014] Embodiment 1 The dyeing and flame-retardant finishing method of wool suit fabric comprises the following steps:

[0015] S1: Put the woolen suit fabric in the dyeing liquor composed of reactive dyes, sodium sulfate, non-ionic surfactant, ammonium polyoxyethylene ether ammonium sulfate, acidic pH regulator and water, the pH of the dyeing liquor is 4.5, The dyeing temperature of the dyeing liquor is 50°C, the temperature of the dyeing liquor is raised to 90°C and kept warm for 7 minutes, the wool suit fabric is taken out, washed and dried;

[0016] S2: Mix β-(N-phenylamide) ethylmethylphosphinic acid, wetting agent and water to prepare a flame-retardant padding solution, and place the wool suit fabric obtained in S1 in the flame-retardant padding solution for at least two The second padding treatment, pre-baking, baking, washing and drying to obtain dyed wool suit fabric with flame retardant function.

[0017] The heating rate of the woolen suit fabric in the dyeing solu...

Embodiment 2

[0021] Example 2 is based on Example 1, the difference is that: the pH value of the dyeing solution is 5.5, the dyeing temperature of the dyeing solution is 45°C, the temperature of the dyeing solution is raised to 90°C and kept for 90 minutes, the wool suit fabric is taken out, washed and dried;

[0022] The heating rate of the wool suit fabric in the dye solution is 1°C / min, and the bath ratio of the wool suit fabric to the dye solution is 1:50.

[0023] The content of reactive dye in the dye liquor is 1.5% (o.w.f.), the content of nonionic surfactant is 2% (o.w.f.), and the content of polyoxyethylene ether ammonium sulfate is 5% (o.w.f.).

[0024] The pH value of the flame retardant padding solution is 6.2, and the content of β-(N-phenylamide) ethylmethylphosphinic acid in the flame retardant padding solution is 5g / L.

Embodiment 3

[0026] Example 3 is based on Example 1, with the difference that the heating rate of the wool suit fabric in the dye solution is 1.25°C / min, and the bath ratio of the wool suit fabric to the dye solution is 1:45.

[0027] The content of reactive dyes in the dye liquor is 2% (o.w.f.), the content of nonionic surfactant is 1.2% (o.w.f.), and the content of polyoxyethylene ammonium sulfate is 6% (o.w.f.).

[0028] The pH value of the flame retardant padding solution is 5.8, and the content of β-(N-phenylamide) ethylmethylphosphinic acid in the flame retardant padding solution is 8g / L.

Abstract

The invention discloses a dyeing and flame-retardant finishing method for a wool suit fabric. The method comprises the two steps of dyeing and flame-retardant finishing, wherein a reactive dye is adopted for dyeing, and an active component of a flame-retardant finishing agent is beta-(N-phenylamide) ethylmethyl phosphinic acid. According to the dyeing and flame-retardant finishing method for the wool suit fabric, the reactive dye is adopted for dyeing, the beta-(N-phenylamide) ethylmethyl phosphinic acid containing nitrogen and phosphorus and having reaction activity is adopted as the active component of the flame-retardant finishing agent, the flame-retardant active component is crosslinked with a wool molecular chain, the obtained wool suit fabric has a similar semi-permanent flame-retardant effect, and the dyeing color depth K / S value is reduced by 15% or below.

Description

technical field [0001] The invention relates to the technical field of fabric manufacturing, in particular to a method for dyeing and flame-retardant finishing of wool suit fabrics. Background technique [0002] The flame retardant finishing of wool is divided into three types: non-permanent, semi-permanent and permanent according to the duration of flame retardant effect. Non-permanent flame-retardant finishing is not resistant to washing. For example, wool can be temporarily flame-retardant after being impregnated and dried in an inorganic acid such as orthophosphoric acid or an organic acid solution such as sulfamic acid. It will fail after washing; semi-permanent flame-retardant finishing can withstand about five washings. , or resistant to multiple washings under specific conditions, permanent flame-retardant finishing can withstand more washing times, semi-permanent and permanent flame-retardant finishing in the prior art such as sulfamic acid and urea rolling and baki...
