Abstract

The invention relates to a staining method of terylene by low temperature plasma. Steps are as follows: (1) Dacron is physical modified by low temperature plasma. Impulse normal pressure plasma or impulse low pressure plasma is applied to deal with dacron.(2) Cationic dye is used for dyeing, which is clean, fast, non-pollution and low cost.

Description

A kind of low temperature plasma terylene dyeing method

Technical field

The invention belongs to textile and dyeing industry, particularly relate to a kind of low temperature plasma terylene dyeing method.

Background technology

The application of lower temperature plasma technology in textile dyeing and finishing is a new technology, the new method of clean production process for spinning.Low temperature plasma is dry type reaction between the gas-solid two-phase to the processing of fabric, and this system has significantly reduced water consumption and the contaminated wastewater in the textile dyeing and finishing processing.This anhydrous process technology has lot of superiority simultaneously, and is extremely low as the consumption of chemicals; Processing is quick, and the general processing time only is a few minutes, even tens seconds, treatment effect only limits to the surface, fiber bodies is had no adverse effects etc.Plasma technique will have good application in weaving aspect the processing.

The method that produces low temperature plasma has a lot, generally have corona discharge (Corona Discharge), dielectric barrier discharge (Dielectric Barrier Discharge, DBD), glow discharge (Glow Discharge) etc.

Terylene (polyethylene terephthalate PET) has advantages such as strong, endurable, but its degree of crystallinity, degree of orientation height, structure are tight, and hygroscopicity, swellability are little, and the big molecule of dyestuff is difficult to be diffused into fibrous inside, thereby dyeing difficulty, and dyeability is poor.In order to solve the chromophobe problem of terylene, except dyestuff and auxiliary agent that exploitation adapts with it, people develop some new polyester kinds, and for example polytrimethylene terephthalate ptt fiber and polybutylene terephthalate (PBT) PBT fiber are in the hope of improving its dyeability.Though but by improving the physics and the chemical constitution of terylene, but it still belongs to hydrophobic fibre, lack the group that as cellulose fiber peacekeeping protein fibre, can combine in the fiber with dyestuff, can not be with the water-soluble dye dyeing of dying cellulose fiber peacekeeping dsred protein fiber, must use relative molecular mass less, do not contain ionic water-soluble group by force, solubility is lower in water nonionic disperse dyeing.Use disperse dyeing to need higher temperature and pressure, caused the waste of the energy and the raising of cost so beyond doubt.

The someone has chemical modification method to handle terylene at present, use cationic dyeing as after anion-modified, the NaOH modification, but the process through chemical finishing is very big to the whole damage of terylene, the intensity of the terylene after the processing descends significantly, and this processing method is more serious to the damage ratio of environment.

Plasma with its cleaning, characteristics attract people's attention gradually efficiently, many people use Cement Composite Treated by Plasma mylar, fiber, fabric, improve its adhesion property, hydrophilicity, dyeability.Because the development of plasma is also only from the fifties, the report that also terylene is not carried out system research and industrialized production with cationic dyeing both at home and abroad.Therefore be necessary it is carried out systematization research, develop as early as possible to promote it.

Summary of the invention

Technical problem to be solved by this invention provides a kind of low temperature plasma terylene dyeing method, this method dyeing cleaning, quick, pollution-free, cost is low.

A kind of low temperature plasma terylene dyeing method of the present invention comprises that step is as follows:

(1) low temperature plasma is to the dacron physical modification

One of technical scheme provides the pulse of air atmospheric plasma and handles dacron,

Two of technical scheme provides the pulse low pressure plasma and handles dacron,

Treatment conditions: power 20-100W, processing time 1-10min, vacuum 30-40Pa;

(2) use cationic dyeing,

With cation dyes at pH3.5-4.5, levelling agent TAN 0.5%, bath raio 1: 50, temperature 80-100 ℃, dyeing time 30-60min dyes.After the washing, oven dry.

Described CATION is selected from the red X-GRL in the nearly river of CATION (C.I.Basic Red 46), the yellow X-GL (C.I.Basic Yellow 28) in the nearly river of CATION, and a kind of among the CATION blue X-BL in nearly river (C.I.Basic Blue 66),

Color of the present invention is obvious, has widened the restriction of dyeing terylene with DISPERSE DYES.
