Description
Technical field
The utility model belongs to new dyeing technical field, specifically a kind of supercritical CO 2 non-aqueous dyeing dyestuff kettle.
Background technology
In traditional dyeing course, we generally adopt and use water as main medium.The sustainable development of environment all can be caused bad impact by the chemical substances such as substantial amounts of dyestuff, surfactant.It additionally, process such as the sewage needs discharging dyeing are neutralized, sedimentations, is required for spending substantial amounts of manpower and materials.According to incompletely statistics, China's textile printing and dyeing industry year water consumption reaches 1,700,000,000 tons, and the discharge of sewage reaches 1,600,000,000 tons.And in recent years, the development further of the serious restriction dyeing and finishing industry of the water resource critical shortage of China's most area, the particularly problems such as sewage discharge.It is therefore prevented that pollute, the green effective dyeing of exploitation, become the correct direction of following dyeing and finishing.
In recent years, a kind of novel green staining method supercritical CO2Non-aqueous dyeing brings new dawn to following dyeing and finishing industry.The excellent features such as this technology has high efficiency due to it, pollution-free, and dyeing time is short, enjoy parent to rely.This technology uses supercritical CO2As dyeing medium, at CO2Heated temperature is more than 31 DEG C, when pressure is more than 7.3MPa, now becomes the state above-critical state of the non-liquid of a kind of non-gas.Then suppressed by circulating pump and constantly circulate between fuel tank and dyeing pot, CO2The dyestuff of dissolving being delivered to the hole of fiber, making dyestuff contaminate evenly and rapidly above fabric, whole process does not needs the process cleaned, dry.At present many countries all have energy-saving and emission-reduction, widely applicable novel green equipment for dyeing and finishing developing of making great efforts is this, it is intended to realized industrialization, practical.
But, as an emerging dyeing industrial equipment, requisite in actual production process there is various problem.In existing supercritical dyeing system, dyeing installation can only successfully contaminate single single color, and such as: red, yellow, blue etc., but for one to be introduced to the market the equipment mass producing, dyeing installation to realize that multiple dyestuff union dyeing is essential.But there is also many problems among these: 1. different dyestuffs is at supercritical CO2In solubility be different, when 120 degrees Celsius, disperse red solubility when pressure is 24 MPas is 2.5/molar fraction × 106, but disperse blue solubility at that same temperature is up to 17.9/molar fraction × 106.So, if simply both dyestuffs being mixed, will result in by the pattern of dyeing and weaving thing.
How the problems referred to above existing for prior art, design a kind of for supercritical CO2The dyestuff kettle of non-aqueous dyeing, reduces pattern, uneven dyeing phenomenon during non-aqueous dyeing, and this is technical problem urgently to be resolved hurrily at present.
