Technical Field

The invention relates to the field of printing and dyeing, in particular to a printing and dyeing method of micro-bead type efficient vapor-permeable cloth.

Background

Also known as dyeing and finishing. Is a processing mode and is also a general term for pretreatment, dyeing, printing, after finishing, washing and the like; the dyeing and finishing specialty of the department is incorporated into the light chemical engineering specialty; as early as six or seven thousand years ago, in the age of neolithic apparatus, our ancestors were able to dye flax red with hematite powder. The original tribe living in the Nuomu flood area of Qinghai Chaida basin can dye the wool into yellow, red, brown, blue and other colors to weave the wool cloth with color stripes. The staining technique is continuously improved during the week period. The palace manual workshop is provided with a professional chihuili 'dyer' to 'palm dye grass', and manages the dyeing production. The color developed is also increasing. By the han generation, staining techniques reached a fairly high level.

Dyes can be classified into water-soluble dyes and insoluble dyes according to their solubility.

After the water-soluble dye is ionic dye and added into water, because water molecules are polar molecules, hydrophilic parts of the dye can form hydrogen bond with the water molecules and form hydrated ions or hydrated molecules with the water according to the strength of hydrophilicity to be dissolved to form aqueous solution of the dye, such as leuco bodies of direct, acidic, active, cationic and vat dyes and sulfur dyes; the solubility is related to factors such as the type of dye, temperature, pH value of dye liquor and the like; adding cosolvent (such as pigment and surfactant) to facilitate the dissolution of dye; the solubility of the naphthol containing hydroxyl is improved under the alkaline condition; containing amino or substituted amino, under acidic condition to produce ammonium salt and ionize into dye cation insoluble azo, and form complex neutral dye with metal ion; the dye is aggregated in different degrees due to the action of hydrogen bonds and Van der Waals force of hydrophobic parts among dye molecules, and the aggregation tendency is a conjugated system which is related to the dye molecular structure, temperature, electrolyte, dye concentration and the like, has a complex molecular structure, large molecular mass and the same plane, is easy to aggregate, has low temperature and large aggregation tendency, is added with the electrolyte, and has increased aggregation, high concentration and large aggregation tendency; in the dye liquor, there is a dynamic balance relation among dye ions, molecules and aggregates thereof, the dye-uptake on the fiber is carried out in a single molecule or ion state, and the aggregates are continuously depolymerized along with the dye-uptake until the balance is achieved.

Insoluble dyes have low solubility in water, such as disperse dyes, vat dyes, and the like. In actual dyeing, the dye amount is far larger than the solubility of the dye, the dye mainly exists in a dispersed state in water, and the dye particles are stably dispersed in a solution by the action of a surfactant to form a suspension
