Abstract
The invention relates to a method for improving the color fastness to sunlight of a cotton fabric dyed with sodium copper chlorophyllin. In the method, natural pagodatree flower buds are added in a dyeing process. The method specifically comprises the following three methods of treating the fabric by using the natural pagodatree flower buds before dyeing, adding the natural pagodatree flower buds in a dye liquid and treating by using the natural pagodatree flower buds after dyeing. According to the method disclosed by the invention, the pagodatree flower buds are added in the dye liquid; and the difference between dyed fabric and the dyeing fabric without adding the pagodatree flower buds cannot be distinguished with naked eyes and the color fastness to sunlight of the dyed fabric is better.
Description
Technical field
The present invention relates to a kind of method that improves the sun-resistant fastness of sodium copper chlorophyllin dyeing cotton fabric, belong to the textile dyeing and finishing field.
Chlorophyll is to distribute on the earth the most extensively, mainly to be present in one of natural colouring matter in the green plants, but very unstable.Sodium copper chlorophyllin is the natural chlorophyll derivative; With reactions such as the chlorophyll process saponification of extracting, copperization; And form through refining; Being a kind of very metalloporphyrin of high stability that has, being used for food by international relevant health organization approval, also is the edible natural pigment that China's approval permission is used.Sodium copper chlorophyllin is blackish green powder, has a little metallic luster.
Sodium copper chlorophyllin dye COTTON FABRIC, its color fastness to washing, flatiron sub limation fastness, colour fastness to perspiration, fastness to rubbing etc. are all better, but sun-resistant fastness is relatively poor.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of method that can improve the sun-resistant fastness of sodium copper chlorophyllin dyeing cotton fabric is provided.
The objective of the invention is to realize like this: a kind of method that improves the sun-resistant fastness of sodium copper chlorophyllin dyeing cotton fabric; In dyeing course, add the natural sophora bud in the said method, comprise three kinds of methods: handle with the natural sophora bud with the natural sophora bud of adding, dyeing back in natural sophora bud processing fabric, the dye liquor before the dyeing.Three kinds of methods are specific as follows:
Method one: handle fabric with the natural sophora bud before the dyeing
The first step, use sophora bud pre-treatment
Treatment conditions: the natural sophora bud of the heavy percentage of 0.1 ~ 0.5% fabric, the heavy percentage paregal O of 0.1 ~ 1% fabric, 40 ~ 100 ℃ of temperature, time 10 ~ 60min, bath raio 1:10 ~ 1:60, the heavy percentage (o.w.f) of crosslinking agent CX-100 5 ~ 15% fabrics.
Second step, copper chlorophyll salt dyeing
The COTTON FABRIC of handling is placed dye liquor, and the mass concentration of sodium copper chlorophyllin is 1 ~ 10 g/l in the dye liquor, salt 5 ~ 15 g/l, the heavy percentage of paregal O 0.1 ~ 1% fabric, 50 ~ 100 ℃ of dyeing temperatures, time 30 ~ 80min, bath raio 1:10 ~ 1:60.
Method two: add the natural sophora bud in the dye liquor
The COTTON FABRIC of handling is placed dye liquor, and the mass concentration of sodium copper chlorophyllin is 1 ~ 10 g/l in the dye liquor, adds the natural sophora bud of the heavy percentage of 0.1 ~ 0.5% fabric; Salt 5 ~ 15 g/l, the heavy percentage of paregal O 0.1 ~ 1% fabric, crosslinking agent CX-100 5 ~ 15% (o.w.f); 50 ~ 100 ℃ of dyeing temperatures, time 30 ~ 80min, bath raio 1:10-1:60; In this co-bathing dyeing technology, the 0 ~ 60min of the joining day of the natural sophora bud for dyeing after beginning.
Method three: handle with the natural sophora bud dyeing back
First step dyeing
Dyeing: the COTTON FABRIC that will handle places dye liquor, and the mass concentration of sodium copper chlorophyllin is 1 ~ 10 g/l in the dye liquor, salt 5 ~ 15 g/l; The heavy percentage of paregal O 0.1 ~ 1% fabric; 50 ~ 100 ℃ of dyeing temperatures, time 30 ~ 80min, bath raio 1:10 ~ 1:60.
Second goes on foot, handles with the sophora bud
Treatment conditions: the natural sophora bud of the heavy percentage of 0.1 ~ 0.5% fabric, the heavy percentage paregal O of 0.1 ~ 1% fabric, 40 ~ 100 ℃ of temperature, time 10 ~ 60min, bath raio 1:10 ~ 1:60, crosslinking agent CX-100 5 ~ 15% (o.w.f).
The invention has the beneficial effects as follows:
Sodium copper chlorophyllin is a kind of natural dye of food-grade, studying the dyeing that is used for textiles at present, but the sun-resistant fastness of DYED FABRICS is lower.The sophora bud also is a kind of natural dye, and is nontoxic, is faint yellow; It has the function of good absorption daylight middle-ultraviolet lamp, in dye liquor, adds an amount of sophora bud, the fabric that dyes with do not compare with the DYED FABRICS of the sophora bud; Can not differentiate through naked eyes variant, but its sun-resistant fastness will be got well.
Because have hydroxyl on the natural sophora bud, can and cellulosic fabric between rely on hydrogen bonded, in order to improve its fastness, can add crosslinking agent.
The above-mentioned dyeing of taking, through the light fastness of test dyeing back fabric, the result shows; When in dye liquor, having increased an amount of sophora bud respectively, its color feature value of the COTTON FABRIC that dyes is more or less the same, and can not differentiating through naked eyes has difference; But shining under the daylight of mid or late December about 20 days; Through with the comparison of the dyed cotton fabric of the sophora bud, find that not DYED FABRICS with the sophora bud phenomenon of fading is obvious, and fade few with the DYED FABRICS of the sophora bud.
The specific embodiment
The present invention relates to improve the method for the sun-resistant fastness of sodium copper chlorophyllin dyeing cotton fabric, said method has three kinds:
First kind:, be divided into for two steps earlier with the green uniformly dyeing look of sophora bud preliminary treatment posterior lobe:
The first step: use sophora bud pre-treatment
Treatment conditions: the natural sophora bud of the heavy percentage of 0.1 ~ 0.5% fabric, the heavy percentage paregal O of 0.1 ~ 1% fabric, 40 ~ 100 ℃ of temperature, time 10 ~ 60min, bath raio 1:10 ~ 1:60, the heavy percentage (o.w.f) of crosslinking agent CX-100 5 ~ 15% fabrics
Second step: copper chlorophyll salt dyeing
The COTTON FABRIC of handling is dyeed according to following dyeing
Dyeing: the mass concentration of sodium copper chlorophyllin is 1 ~ 10 g/l, salt 5 ~ 15 g/l, the heavy percentage of paregal O 0.1 ~ 1% fabric, 50 ~ 100 ℃ of dyeing temperatures, time 30 ~ 80min, bath raio 1:10 ~ 1:60;
Second kind of chlorophyll and sophora bud co-bathing dyeing
Dyeing: the mass concentration of sodium copper chlorophyllin is 1 ~ 10 g/l, the natural sophora bud of the heavy percentage of 0.1 ~ 0.5% fabric, salt 5 ~ 15 g/l; The heavy percentage of paregal O 0.1 ~ 1% fabric; The heavy percentage (o.w.f) of crosslinking agent CX-100 5 ~ 15% fabrics, 50 ~ 100 ℃ of dyeing temperatures, time 30 ~ 80min; bath raio 1:10-1:60
In co-bathing dyeing technology, the 0 ~ 60min of the joining day of the natural sophora bud for dyeing after beginning.
The third uses earlier the copper chlorophyll salt dyeing, and handle with the sophora bud back
First step dyeing
Dyeing: the mass concentration of sodium copper chlorophyllin is 1 ~ 10 g/l, salt 5 ~ 15 g/l, and paregal O 0.1 ~ 1%, 50 ~ 100 ℃ of dyeing temperatures, time 30 ~ 80min, bath raio 1:10 ~ 1:60,
Second step: handle with the sophora bud
Treatment conditions: the natural sophora bud of the heavy percentage of 0.1 ~ 0.5% fabric, the heavy percentage paregal O of 0.1 ~ 1% fabric, the heavy percentage (o.w.f) of crosslinking agent CX-100 5 ~ 15% fabrics, 40 ~ 100 ℃ of temperature, time 10 ~ 60min, bath raio 1:10 ~ 1:60.
