Description

Method for rapidly determining availability of gambiered plant gambiered Guangxi yarn Wu river mud

Technical Field

The invention belongs to the field of dyeing and finishing of gambiered plant muskmelon, and particularly relates to a method for quickly determining availability of gambiered plant muskmelon river mud.

Background art:

the gambiered Canton gauze is a double-sided heterochromatic traditional silk fabric which is unique to Guangdong Shuider, and the generation of the gambiered Canton gauze can be traced back to the Ming dynasty and has a history of more than six hundred years to date; it is solid in color, unique in texture and antique in style, and is still a high-grade material for clothing up to now. The gambiered plant gambiered plant gambiered plant gambiered plant gambiered gambier. The specific production process flow is as follows: silk preparation → potato yam ball juice → sun-dried buttercup → repeated sun-dried buttercup → monkshood (covering river mud) → washing → sun-drying → fog spreading → rolled silk for package. Wherein the 'over-black' is the key for obtaining the black and bright color of the front surface of the gambiered plant gauze.

However, since the river gush in the zhujiang delta is seriously polluted in the urbanization process, the available river mud is sharply reduced, and the sustainable production of the gambiered plant is threatened, so that the river mud is very necessary to be screened widely, and meanwhile, a method for rapidly determining the availability of the river mud can provide convenience for screening the river mud.

In the past, the availability of the river mud is generally judged by a dyeing and finishing master with abundant experience according to experience, the scientificity is lacked, the actual dyeing and finishing effect is generally known after the river mud is taken back to a production factory for test dyeing, and the method has hysteresis and wastes silk.

FIG. 3 is a comparison of color developing solution of acid extract of river mud with a standard color chart (CMKY color system).

The specific implementation mode is as follows:

the following examples are further illustrative of the present invention and are not intended to be limiting thereof.

Example 1:

first, the over-black effect of river mud with different ferrous content

Dyeing and finishing the model: taking a plurality of river muds (from Fushanlungzhi, Romura river and Zhujiang front channel) with different ferrous contents, centrifuging at 3500rpm, and pouring out the supernatant; adding equivalent deionized water into each sample to adjust the mud into a mud state; spreading the same amount of slurry on the gambiered canton silk which has been subjected to gambiered canton liquid, and standing for 1 hour; washing to remove slurry on the silk, and naturally drying to obtain over-black cloth, as shown in figure 1.

And (3) judging the over-black effect: identifying the blackened cloth by a non-material cultural heritage inheritance heritage of a gambiered plant yarn dyeing and finishing process; the color parameter L of the non-self-illumination of the cloth surface was determined by means of an UltraScan PRO spectrocolorimeter (Datacolor 110. TM., USA).

Secondly, measuring the color development chromaticity and the absorbance of the color development liquid of the acid extracting solution of the river mud with different ferrous contents

1) Preparation of the experiment: preparing 1M hydrochloric acid solution (commercially available analytically pure concentrated hydrochloric acid (12M) diluted 12-fold), 0.1g/mL sodium acetate solution (10 g of sodium acetate added to 100mL of water), and 0.001g/mL phenanthroline solution (0.1 g of phenanthroline added to 100mL of water); preparing quantitative spoons (commercially available 0.25g semicircular spoons), 5mL and 10mL transparent centrifuge tubes;

2) extracting acid-soluble iron ions:

weighing 1 flat spoon (about 0.6g fresh weight) of river mud with a commercially available quantitative spoon, placing in 5mL of 1M hydrochloric acid solution, shaking, and standing for 10min to obtain extractive solution A; measuring 0.1mL of the supernatant of the extractive solution A, and placing in 9.9mL of 1M hydrochloric acid solution to obtain extractive solution B (acid extractive solution of river mud);

3) developing the color of the extracting solution: measuring 1mL of extracting solution B, adding 2mL of 0.1g/mL sodium acetate solution and 2mL of 0.001g/mL phenanthroline solution, shaking uniformly, and standing for developing for 5min to obtain a developing solution;

4) and (3) performing color comparison on an extracting solution: and (3) carrying out colorimetry on the color development liquid after the color development is stable and a CMYK standard color card or measuring the absorbance of the color development liquid at 510 nm.

Thirdly, experimental results:

as shown in fig. 1, the black color of the front surface of the over-blackened cloth is related to the color development chromaticity (ferrous) of the color development liquid of the acid extraction liquid of the river mud, and the deeper the color development is, the deeper the black color dyeing of the front surface of the gambiered plant yarn is, the better the over-blacking effect of the river mud is.

As shown in fig. 2, the absorbance value of the color developing solution of the acid extract of the river mud is significantly and positively correlated with the non-self-illumination color parameter L on the surface of the musty yarn cloth, wherein L represents brightness, and the numerical value range is from the highest value of 100 (white) to the lowest value of 0 (black), which indicates that the black color of the front surface of the musty yarn can be indirectly represented by the color developing color of the acid extract of the river mud.

As shown in fig. 3, samples No. 11(M ═ 90) and 12(M ═ 100) (cloth after blackening) were identified as successful over-blackening samples by non-genetic support, and the absorbance at 510nm of the chromogenic solution of the acid extract of the corresponding river mud was 2.0 and 2.7, and the chromogenic solution of the acid extract of the corresponding river mud was greater than 90 when compared with CMYK standard colorimetric card (fixed C ═ 0, Y ═ 100, K ═ 0).

Therefore, the color developing solution of the acid extracting solution of the river mud has the absorbance of more than or equal to 2.0 at 510nm or is compared with a CMYK standard color comparison card, the river mud corresponding to the fixed value of C being 0, Y being 100, K being 0 and M being more than 90 is the river mud which can be used for the gamboge gauze overuse.
