Abstract

The invention relates to a natural yellow series cotton fabric and belongs to the field of spinning. The cotton fabric is a pure cotton woven plus material, the dye is henna, the henna is selected and is pulverized into 10 to 100 meshes of powder by a pulverizer, water is added for heating solution, then, the filtering is carried out, and solid and water solution are in separated placement; the solid is placed in an extraction tank, ethanol solution is added, the stirring is carried out for extracting natural dye liquor, and the ratio of the solid to the ethanol solution is 1:1-1:20, and dye liquor A is obtained after filtering; the solid subjected to filtering is added into the ethanol solution for secondary extraction and filtering, the filtered dye liquor, the dye liquor A and the water solution are mixed, and dye extraction liquid is obtained; the dye extraction liquid is concentrated through a rotary evaporimeter, the vacuum degree of the rotary evaporimeter is 0.085 MPa, the water bath temperature is 65 to 75 DEG C, and dye concentrated liquor is prepared; the a pure cotton woven plus material is placed in a dyeing vat, the dye concentrated liquor, the water and dye mordant are added, the heat insulation is carried out to 90 DEG C, the dyeing is carried out for 2 hours, the temperature is lowered to the room temperature, and the pure cotton woven plus material is taken out; and the pure cotton woven plus material is washed by water and dried. The raw material obtaining is convenient, the production process is simple, the integral production is adopted, and the production efficiency is high. Good dye-uptake rate is realized on the dyeing of pure cotton fabrics.

Description

Natural yellow is COTTON FABRIC

Technical field

The present invention relates to natural yellow is COTTON FABRIC, and it belongs to field of textiles.

Background technology

Raising along with people's living standard, quality of life and living environment are more and more paid attention to, the biodegradation of natural plant dye self energy, do not affect environment, vegetable colour source plant can enlarge plantation, continuous production, and it is applied to textile dyeing, has significant Social benefit and economic benefit.The garden balsam plant contains pigment, is a kind of good pure natural dyestuff.The dyeing that is used for pure cotton fabric has good dye-uptake.

Summary of the invention

In view of the defective that prior art exists, the object of the present invention is to provide natural yellow is COTTON FABRIC, makes its technique simple, and production efficiency is high, easily extracts the natural plant dye with dyeing function.

For achieving the above object, the technology used in the present invention solution is that natural yellow is COTTON FABRIC, and COTTON FABRIC is textile woven fabric, dyestuff is garden balsam, chooses garden balsam, is ground into 10-100 purpose powder with pulverizer, add the water heating for dissolving, filter, solid and the aqueous solution split; Solid places extractor, adds ethanolic solution, stirs and extracts natural dye liquor, and solid is 1:1-1:20 with the ratio of ethanolic solution, namely gets dye solution A after the filtration; Solid after the filtration adds ethanolic solution and again extracts filtration, and the dye solution after the filtration, dye solution A and described aqueous solution obtain the dyestuff extract; The dyestuff extract is concentrated by Rotary Evaporators, vacuum 0.085 MPa of described Rotary Evaporators, bath temperature is 65-75 ℃, makes dye concentrated solution; Textile woven fabric is placed in the dye vat, add dye concentrated solution, water and mordant, insulation is to 90 ℃, on dyed 2 hours, be down to room temperature and take out; With textile woven fabric washing, oven dry.Described heating-up temperature is 60-80 ℃.

After adopting such scheme, compared with prior art have following beneficial effect: raw material sources are convenient, and production technology is simple, integrated production, and production efficiency is high.The dyeing that is used for pure cotton fabric has good dye-uptake.

The specific embodiment

Following the present invention is described further in connection with embodiment:

Natural yellow is COTTON FABRIC, and COTTON FABRIC is textile woven fabric, and dyestuff is garden balsam, chooses garden balsam, is ground into 10-100 purpose powder with pulverizer, adds the water heating for dissolving, filters again, and solid and the aqueous solution split; Solid places extractor, adds ethanolic solution, stirs and extracts natural dye liquor, and solid is 1:1-1:20 with the ratio of ethanolic solution, namely gets dye solution A after the filtration; Solid after the filtration adds ethanolic solution and again extracts filtration, and the dye solution after the filtration, dye solution A and described aqueous solution obtain the dyestuff extract; The dyestuff extract is concentrated by Rotary Evaporators, vacuum 0.085 MPa of described Rotary Evaporators, bath temperature is 65-75 ℃, makes dye concentrated solution; Textile woven fabric is placed in the dye vat, add dye concentrated solution, water and mordant, insulation is to 90 ℃, on dyed 2 hours, be down to room temperature and take out; With textile woven fabric washing, oven dry.Described heating-up temperature is 60-80 ℃.

The garden balsam raw material sources are convenient, and production technology is simple, integrated production, and production efficiency is high.The dyeing that is used for pure cotton fabric has good dye-uptake.
