Abstract
The invention provides a natural purple cotton fabric, belonging to the field of spinning. The cotton fabric is a pure cotton woven fabric. The dye is lithospermum. The cotton fabric is prepared by the steps of: selecting lithospermum, grinding lithospermum into 10-100-mesh powder with a grinder, putting the powder into an extracting tank, adding ethanol water solution, stirring the mixture to extract natural dye liquor and filtering to obtain dye liquor A, wherein the ratio of the lithospermum raw material to ethanol is (1:1)-(1:20); adding ethanol to the solid obtained after filtration to re-extract the solid, filtering the extract and mixing dye liquor obtained after filtration with the dye liquor A to obtain dye extracting liquor; drying and concentrating the dye extracting liquor via a rotary evaporator to prepare dye concentrated liquor, wherein the vacuum degree of the rotary evaporator is 0.085MPa and the water bath temperature is 50-60 DEG C; putting the pure cotton woven fabric into a dye vat, adding the dye concentrated liquor, water and a mordant, preserving heat to 90 DEG C, dyeing the pure cotton woven fabric for two hours, cooling the pure cotton woven fabric to the room temperature and taking out the pure cotton woven fabric; and washing and then drying the pure cotton woven fabric. The natural purple cotton fabric has the beneficial effects that the raw materials are convenient in sources; the production process is simple; the natural purple cotton fabric is integrally produced; the production efficiency is high; and the dye has good dye uptake when being used for dyeing the pure cotton fabric.
Description
Technical field
The present invention relates to natural violet COTTON FABRIC, 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 Asian puccoon 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
Defective in view of prior art exists the object of the present invention is to provide natural violet 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 natural violet COTTON FABRIC, COTTON FABRIC is textile woven fabric, and dyestuff is Asian puccoon, chooses Asian puccoon, be ground into 10-100 purpose powder with pulverizer, be placed in extractor, add ethanol water, stir and extract natural dye liquor, the Asian puccoon raw material is 1:1-1:20 with the ratio of ethanol, namely gets dye solution A after filtration; Solid after filtration adds ethanol again to extract filtration, and the dye solution after filtration and dye solution A are mixed to get the dyestuff extract; The dyestuff extract is dry concentrated by Rotary Evaporators, vacuum 0.085 MPa of described Rotary Evaporators, bath temperature is 50-60 ℃, makes dye concentrated solution; Textile woven fabric is placed in dye vat, adds 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.In described ethanol water, the mass fraction of water is 50-90%.Described heating-up temperature is 70-95 ℃.
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 violet COTTON FABRIC, COTTON FABRIC is textile woven fabric, dyestuff is Asian puccoon, choose Asian puccoon, be ground into 10-100 purpose powder with pulverizer, be placed in extractor, add ethanol water, stir and extract natural dye liquor, the Asian puccoon raw material is 1:1-1:20 with the ratio of ethanol, namely gets dye solution A after filtration; Solid after filtration adds ethanol again to extract filtration, and the dye solution after filtration and dye solution A are mixed to get the dyestuff extract; The dyestuff extract is dry concentrated by Rotary Evaporators, vacuum 0.085 MPa of described Rotary Evaporators, bath temperature is 50-60 ℃, makes dye concentrated solution; Textile woven fabric is placed in dye vat, adds 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.In described ethanol water, the mass fraction of water is 50-90%.Described heating-up temperature is 70-95 ℃.
The Asian puccoon 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.
