Abstract
The invention discloses a new process for scouring and dyeing polyester cotton in a one bath manner. The process comprises the steps of dyeing, soaping, fixing color, rinsing, dewatering and drying. Raw materials without formaldehyde and APEO and with easiness in biologic degradation and environmental-friendliness are utilized. A new printing and dyeing agents SR synthesized by a macromolecule polymerization reaction is environmental friendly, and also has the characteristics of high temperature resistance, electrolyte resistance, wide pH vale range and stability; the dyeing process requirements are completely met, the product quality is stable, and the use effects of products in different batches are the same. During the pre-treatment, use of alkali in the traditional treatment process is prevented for pretreatment, so that the problems that hardly repaired alkali spots are generated because the rinsing is incomplete and the fabric surfaces have residual alkali after the fabrics are boiled in alkali liquid is completely avoided, and the stability and the reproducibility of the process are ensured; the technical procedure is shortened, and the purposes of saving energy, reducing emission and improving the machining efficiency and quality are realized.
Description
Technical field
The invention belongs to dyeing, be specifically related to a kind of polyester-cotton blend scouring and dyeing new technology.
Background technology
Polyester-cotton fabric is one of weaving face fabric most popular with consumers, due to containing polyester-cotton blend bi-component, has taken into account the advantage of two kinds of fibers, has had cheap, that good hygroscopicity, shape-retaining ability are good advantage.But due to containing different component, dyeing course is comparatively loaded down with trivial details, traditional Colour Difference must comprise cotton component pre-treatment, washs dyeing, cotton dyeing three flow processs, not only time-consuming, and power consumption is large, efficiency process point that is low, quality control is many, and product quality is wayward.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of polyester-cotton blend scouring and dyeing new technology is provided, shorten technological process, reach energy-saving and emission-reduction, improve the object of working (machining) efficiency and quality.
Polyester-cotton blend scouring and dyeing new technology provided by the invention, technological process is as follows:
A () is dyeed: polyester-cotton blend is put into 40 DEG C of solution containing SR, soaks to add acetic acid, DISPERSE DYES after 30min and to operate in BOF 10 min, is warming up to 130 DEG C of insulation 40 min, cooling reduction cleaning;
B () soaps: in containing the solution of Chinese honey locust 0.25-0.4g/L, carry out soap boiling to polyester-cotton blend, soap boiling temperature is 90 DEG C;
(c) fixation: polyester-cotton blend is immersed in the soda ash solution of 85 DEG C and carry out fixation, the fixation time is 20-40min;
D () washes: use clean water polyester-cotton blend;
(e) dewatered drying.
Polyester-cotton blend scouring and dyeing new technology provided by the invention, its beneficial effect is, uses not containing formaldehyde, APEO, easily biological-degradable, eco-friendly raw material, by the novel printing and dyeing finishing agent SR that macromolecular polymerization reaction synthesizes, not only environmental protection, and have high temperature resistant, the feature of the stability of electrolyte-resistant, wide ph range, meet dyeing requirement completely, ensure the product with stable quality of producing, the result of use of different batches is identical.Use alkali to carry out pre-treatment owing to avoiding in conventional machining process, because washing is not thorough, cloth cover lixiviating not to the utmost and easily produces the defects such as the alkaline spot being difficult to repair after thoroughly having stopped fabric soda boiling, ensure stability and the repeatability of technique.Shorten technological process, reach energy-saving and emission-reduction, improve the object of working (machining) efficiency and quality.
Detailed description of the invention
Below in conjunction with an embodiment, polyester-cotton blend scouring and dyeing new technology provided by the invention is described in detail.
Embodiment
A () is dyeed: polyester-cotton blend is put into 40 DEG C of solution containing SR, soaks to add acetic acid, DISPERSE DYES after 30min and to operate in BOF 10 min, is warming up to 130 DEG C of insulation 40 min, cooling reduction cleaning;
B () soaps: in containing the solution of Chinese honey locust 0.25-0.4g/L, carry out soap boiling to polyester-cotton blend, soap boiling temperature is 90 DEG C;
(c) fixation: polyester-cotton blend is immersed in the soda ash solution of 85 DEG C and carry out fixation, the fixation time is 20-40min;
D () washes: use clean water polyester-cotton blend;
(e) dewatered drying.
Claims (1)
1. a polyester-cotton blend scouring and dyeing new technology, is characterized in that, processing step comprises:
