Description
Technical Field
The invention belongs to the field of textile printing and dyeing, and particularly relates to a one-bath one-step dyeing method of a wool/polyamide 56 fiber blended fabric.
Background
The one-bath one-step dyeing method is a dyeing process that the blended fabric is dip-dyed by selecting respective dyes in the same dyeing bath and is fixed by the same color fixing process.
The wool fiber as a high-grade natural protein fiber has the advantages of excellent elasticity, plump hand feeling, good heat retention, excellent hygroscopicity and the like. The polyamide 56 has the performance advantages of good elasticity, high wear resistance, high strength and the like of polyamide 6 and polyamide 66, and also has the performance advantages of moisture absorption, softness, low-temperature dyeing and the like. Particularly, the modulus of the polyamide 56 is lower than that of the polyamide 6 and the polyamide 66, the softness is close to that of wool, and the polyamide is more suitable for being blended with the wool. The wool and the polyamide 56 can be blended to integrate the advantages of the wool and the polyamide, and have excellent wearability and unique style.
Amino groups exist at the tail ends of macromolecular chains of wool and polyamide fibers, weak acid dyes and 1:2 metal complex dyes can be adopted for dyeing, but the weak acid dyes and the 1:2 metal complex dyes have obvious differences in dyeing affinity, dyeing rate, dyeing saturation value and the like of the wool and the polyamide fibers due to the difference of molecular structures, crystalline structures and the like of the wool and the polyamide fibers, and color difference is easy to occur during one-bath one-step dyeing, and the phenomena of dark polyamide color and light wool color are generally expressed. The polyamide 56 has a special odd-even molecular chain arrangement mode, has the characteristic of low-temperature dyeing compared with polyamide 6 and polyamide 66, is higher in dyeing rate and dye dyeing affinity, and is more prone to the phenomena of dark polyamide component color and light wool component color compared with polyamide 6 and polyamide 66 when the polyamide 6 and polyamide 66 are subjected to one-bath one-step dyeing by wool weak acid dye or 1:2 metal complex dye, so that the traditional one-bath one-step dyeing method for the wool/polyamide 6 or polyamide 66 fiber blended fabric is not suitable for dyeing the wool/polyamide 56 blended fabric. Therefore, although the one-bath one-step dyeing method is simplified to some extent, many problems occur, such as dye hydrolysis, uneven coloring, occurrence of color shift, color difference and the like. At present, the one-bath one-step dyeing method of the wool/polyamide 56 fiber blended fabric is not disclosed in the related art.
