CN1079267A - A kind of rare-earth dyeing process for loose wool - Google Patents

Abstract

The rare earth flock dyeing is to loose and dye at goats hair, local hair, and used prescription is rare earth chloride, acid mordant dye, sulfuric acid, acetic acid, sodium dichromate, mothproofing agent.Adopt and dye earlier back matchmaker's method technology, bath raio 1: 15,100 kilograms/pot of dyeing quantity, 4 hours 0 10 minutes overall process time.

Loose at traditional of all kinds number and to dye in the prescription, add on 0.2-0.8% rare, deduct 2-8% dye auxiliary material, with the acid amount, subtract glauber salt entirely and draw back powder.

Rare-earths dyeing can make dye colour pure, lovely luster, and good level-dyeing property is avoided the look flower, and COLOR FASTNESS improves the 0.5-1 level, low energy, the surcharge height improves dye-uptake, alleviates environmental pollution.

Description

A kind of rare-earth dyeing process for loose wool

The invention belongs to the wool textile technology field.

About the rare earth element application in the caused by spinning industrial production at home, had only in recent years on knitting wool, knitting wool dyeing, the acrylic fibre dye, the application in the drap-de-berry piece dyeing got better benefited.

Flock dyeing in the domestic caused by spinning industrial production is continued to use traditional diffusing dyeing technique based on mordant dyes always, part look user is reflected the hair color obfuscation of dyeing back, lack light and vividness, look flower phenomenon occurs now and then, and product quality plays pendulum always.

The rare earth flock dyeing is in order to make full use of the rare earth resources application what flock dyeing that my district accounts for national reserves 90%, to open up new dyeing process for loose wool and prescription, increasing high additive value.Not only energy-conservation, low consumption, and will improve to loose and dye product quality, the ratio of first-grade products and the qualification rate of product improved.Conscientiously improve the dyestuff dye-uptake, alleviate and improve that pin water is dense uprises the environmental pollution that causes.

Rare-earths dyeing adopts and dyes back matchmaker's method technology earlier, 4 hours 0 10 minutes overall process time, and dyeing quantity 100kg/ pot, bath raio 1: 15, dyeing is at goats hair, local hair.By weight, if incarnadine, green, the body lotion to 30 ℃ of then heating adds 1. rare earth chloride 0.2-0.8kg, 0.2-0.8kg in turn with 100kg local hair to be dyed; 2. acetic acid 2.8kg, 0.9kg, 3. acid mordant dye 2.959kg, 1.48kg rise to 100 ℃ of boiling water states by 1 ℃/minute Wen Su then; Keep adding in turn after 10 minutes, 4. sulfuric acid 0.24kg, 1kg, continue to keep boiling water to go liquid 1/3 to add water for cooling to 80 ℃ after 40 minutes, add again in turn, 5. sulfuric acid 0.24kg, 0.4kg, 6. sodium dichromate 1.25kg, 0.76kg, 7. mothproofing agent 0.6kg, 0.6kg, rise to 100 ℃ of boiling water states with 1 ℃/minute again and kept 50 minutes, last flushing with clean water goes out machine three times.With 100kg goats hair to be dyed if incarnadine, green, brown, then heat body lotion to 30 ℃, add 1. rare earth chloride 0.2-0.8kg, 0.2-0.8kg, 0.2-0.8kg in turn, 2. acetic acid 1.9kg, 0.9kg, 1.9kg, 3. acid mordant dye 2.09kg, 1.71kg, 2.38kg, rising to 100 ℃ of boiling water states by 1 ℃/minute Wen Su then keeps adding in turn in 10 minutes, 4. sulfuric acid 0.48kg, 1kg, 0.5kg, continue to keep boiling water to go liquid 1/3 to add water for cooling to 80 ℃ after 40 minutes, add 5. sulfuric acid 0.47kg, 1.4kg, 0.45kg in turn again; 6. sodium dichromate 1kg, 0.85kg, 1.14kg; 7. mothproofing agent 0.6kg; 0.6kg, 0.6kg; Rise to 100 ℃ of boiling water states with 1 ℃/minute again and kept 50 minutes, last clear water dashes to select and goes out machine three times.Promptly loose and dye in the prescription, add the rare earth of 0.2-0.8% at traditional of all kinds number, deduct 2-8% dye auxiliary material, with the acid amount, original formulation uses glauber salt and draws back pink colour person and subtracts glauber salt entirely, draws back powder.

Rare-earths dyeing makes full use of me and distinguishes abundant rare earth resources application what flock dyeing, makes resources advantage sell of one's property product advantage, and low energy has been opened up new dyeing process for loose wool and prescription.Rare-earths dyeing makes that to dye the thing color pure, lovely luster, and soft and bright, good level-dyeing property, COLOR FASTNESS improves the 0.5-1 level, and production run, physical index are stable.Product surcharge height improves the diffusing ratio of first-grade products and qualification rate of dying product, increases the dyeing flower chromaticity kind of loosing, and auxiliary material is dyed in the low energy saving, reduces product cost, i.e. 5.44 yuan/pot of more of all kinds number average saving of rare-earths dyeing and traditional dyeing recipe ratio.Improve the quality of products, because of the rare-earths dyeing dye-uptake improves, promptly dye utilization rate height and the dense step-down of pin water greatly alleviates and improved environmental pollution has tangible mixed economy, social benefit.
