Piece dyeing technique of alpaca fiber, wool and nylon

Abstract

The invention discloses a piece dyeing technique of alpaca fiber, wool and nylon. The technique includes steps of step one: pretreatment of alpaca fiber; step two, piece dyeing of alpaca fiber, wool and nylon; the piece dyeing process mainly includes (1), sewing alpaca fiber, wool and nylon to be a fabric and then placing in a dye cylinder; adding pretreatment agent; (2), heating the dye cylinderto 80 DEG C at the heating rate of 1 DEG C / min and then preserving temperature for 20 minutes; cleaning the fabric; (3), adding dye leveler, penetrant, blocking agent and dye; running the dyeing cylinder for 25 minutes, and heating it to 60 DEG C at the heating rate of 1.5 DEG C / min, and preserving temperature for 15 minutes; heating to 75 DEG C at the heating rate of 1.5 DEG C / min, preserving temperature for 20 minutes and then fixing the dye; (4), heating the dye cylinder to 100 DEG C at the heating rate of 1 DEG C / min; if tint is dyed, preserving temperature for 70 minutes and then coolingand cleaning; if deep color is dyed, preserving temperature for 100 minutes, and dyeing deep color and then performing soaping treatment. The piece dyeing technique can perform piece dyeing on a mixedfabric of the alpaca fiber, wool and nylon.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing technology, in particular to a piece dyeing technology for alpaca, wool and nylon. Background technique [0002] Alpaca, also known as alpaca, belongs to camel hair fiber. It is soft, white, brown, fawn or black in color, and its strength and warmth are much higher than that of wool. There are four purebreds of alpacas: Vicuna, Alpaca, Werkona and Gannaco. After Alpaca was crossed with llamas, two hybrids were produced: the offspring of alpaca rams and Alpaca ewes was called Hualicha; the offspring of Alpaca rams and llama ewes was called Misi ladder. [0003] Because alpaca has many advantages, more and more alpaca is used as fabric in the existing textile industry. Some current fabrics are made of a mixture of alpaca, wool and nylon, but because the wool of alpaca is thick, it is difficult to color, while wool and nylon are relatively thin and easy to dye. If they are mixed together f...

Problems solved by technology

Some current fabrics are made of a mixture of alpaca, wool and nylon, but because the wool of alpaca is thick, it is difficult to color, while wool and nylon are relatively thin and easy to dye. If they are mixed together for dyeing, the dye Both will be dyed on wool and nylon, so the existing treatment method is to dye alpaca, wool and nylon separately, and then weave them into fabrics, which will cause low dyeing efficiency and cannot meet the batches of enterprises chemical high production
