Abstract
The invention relates to an environment-friendly pigment dyeing process which specifically comprises the following steps: (1) performing the following process flow, namely performing pretreatment scouring and bleaching, removing hair and enzymes, performing cationic agent treatment, washing with water, performing pigment dyeing, washing with the water, fixing, dewatering, drying and setting; (2) performing knitted fabric pretreatment; (3) performing cationic modification treatment, namely dyeing at room temperature by using a cationic modification agent, regulating the pH value, controlling the heating speed to be 1-2 DEG C per minute, controlling the test bath ratio to be 1 to (25-30), heating to the temperature of 60-70 DEG C, preserving the temperature for 20-30 minutes, washing with the water at the normal temperature, and performing the pigment dyeing; and (4) performing the pigment dyeing, wherein in the dyeing test stage, the initial dyeing temperature is generally controlled to be 30-40 DEG C, the heating speed is controlled to be 1-2 DEG C per minute, the test dyeing temperature is 60-70 DEG C, and the heat preservation time is 20-30 minutes. The process disclosed by the invention is environmentally friendly, good in effect and obvious in benefit, and pigments can be well dyed.
Description
Technical field
The present invention relates to a kind of environmental protection coating material dyeing, belong to pigment dyeing technical field.
Background technology
Its technique of pigment dyeing is simple, bright in colour, flow process is shorter, and is not too high to the requirement of equipment; Pigment printing paste chromatogram is complete, has good sublimation reliability and sunlight fastness, and it has a set of gorgeous fluorescence chromatogram that REACTIVE DYES can not be compared; Pigment dyeing is to the strong adaptability of fiber, and repeatability is relatively good, and form and aspect are stablized, and can be applicable to the dyeing of cotton fiber and blending or intertexture, can obtain the fabric effect of unique style, novel fashion simultaneously.
The another large feature of pigment dyeing, it meets the theory of current eco-dyeing and finishing, energy-saving and emission-reduction very much, and have and save the energy, feature that environmental pollution is little, it is again one and takes into account cleaner production, economize energy and raw-material innovative technology; Wherein pigment dyeing technology was once classified as in key industry production technology guidance quality catalogue by State Economic and Trade Commission, went research and development as new technology.
In recent years, along with market is to the demand of pigment dyeing product style, dyeing and finishing industry and associated garments industry thereof are to the attention of the variety development work of pigment dyeing, the pad dyeing of pigment dyeing, dip-dye and ready-made clothes dyeing technique are further enhanced, for the development of expanding textile garment market plays a role; But for knit fabric, compare from the coating pad dyeing process of routine and also exist larger different, overflow dyeing equipment carries out produce in batches there is problems in some production practices simultaneously; Because the structure of knit fabric is special, after pigment dyeing, easily there is look flower, folding line and cloth cover mantle friction trace; Still there is the weak points such as crock fastness (dry, wet friction and scrub friction) is poor.
Summary of the invention
The object of the present invention is to provide a kind of environmental protection coating material dyeing, more to carry out pigment dyeing to environmental protection.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of environmental protection coating material dyeing, specifically comprises:
(1) technological process: pre-treatment is scouringed and bleaching---defeathering ferment---cationics process---washing---pigment dyeing---washing---set---dehydration---oven dry---sizing;
(2) knitted cloth pre-treatment requires: due to cotton knitted cloth embryo cloth existing a large amount of finishes, boll hull and impurity etc., conventional pre-treatment Scouring and bleaching process must be adopted, abundant removal impurity, the wettability that maintenance fabric is good and permeability, capillary effect good (test fabric controls at 8-10cm/30 minute); In order to improve and improve the adsorption effect of coating to fabric and the fineness of cloth cover, the polishing of defeathering ferment is carried out to the knitted cloth after pre-treatment;
(3) cation modifying process: cation modifying agent room temperature enters dye, regulates pH value, and programming rate is at 1-2 DEG C/min, and test bath raio, at 1:25-30, is warmed up to 60-70 DEG C of insulation 20-30 minute, after normal temperature washing, treats pigment dyeing;
(4) pigment dyeing: the dye test stage comprises the dye temperature that begins, programming rate and final dyeing temperature, the dye that begins temperature general control is at 30-40 DEG C, and programming rate controls at 1-2 DEG C/min, and test dyeing temperature is at 60-70 DEG C, and temperature retention time is at 20-30 minute.
This beneficial effect of the invention is: present invention process environmental protection, and can coating be utilized preferably to dye, effective, income be obvious.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described, better to understand the present invention.
