Description

Technical Field

[0001] The invention belongs to the technical field of textile materials, and in particular relates to an environmentally friendly process method for dyeing wool fabrics by using ginseng pulp. Background Art

[0002] Natural dyes are obtained from different parts of plants through certain extraction methods. Due to the advantages of these dyes being widely available, non-toxic, harmless, eco-friendly and easily biodegradable, natural dyes are widely used in the dyeing and design production of high-end clothing and home textiles, adding natural, safe and environmentally friendly characteristics to these products.

[0003] Ginseng fruit, also known as melon eggplant, is oval or conical in shape. When ripe, the peel is light yellow, some have purple stripes, and the flesh is yellow. At present, most of the research on ginseng fruit as raw materials is in the field of food engineering, such as patent document number CN103549313A for a method of extracting ginseng fruit essence, and patent document number CN102613630A for a method of preparing juice with high trace element content. Current research on ginseng fruit mainly focuses on its nutritional value and medicinal value. There are relatively few studies on it as a natural dye, and a systematic preparation method and application system have not yet been formed.

[0004] The present invention aims to provide an environmentally friendly process for dyeing wool fabrics with ginseng pulp. By extracting pigments from the pulp of ginseng fruit to prepare natural dyes, and using the pigments to dye textiles, an environmentally friendly textile dyeing method is developed, thereby providing practical experience for the application of natural dyes in the textile industry. Summary of the invention

[0005] The purpose of the present invention is to provide an environmentally friendly process method for dyeing wool fabrics using ginseng fruit pulp, by extracting pigments from ginseng fruit pulp and exploring its coloring effect on protein fiber wool fabrics, so as to solve the above-mentioned background technology of preparing plant dyes from ginseng fruit and applying them in the textile field.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An environmentally friendly process for dyeing wool fabric using ginseng pulp comprises the following steps:

[0008] S1. Preparation of base fabric: (1) Cut wool fabric into fabric samples; (2) Weigh and record the cut fabric samples respectively, and calculate the sample average value;

[0009] S2. Preparation of dye: (1) peeling and crushing an appropriate amount of ginseng fruit and filtering the mixture several times to obtain a solution of ginseng fruit pulp; (2) pouring the solution into a beaker; (3) heating the beaker in a water bath for 0.5 to 1 h and filtering the mixture to obtain ginseng fruit dye;

[0010] S3. Preparation of dyed fabrics: (1) Place the fabric sample in ginseng fruit dye with a bath ratio of 1:60, soak and stir continuously, then add appropriate amounts of NaOH and NaCl, continue to stir continuously, (2) Take out the fabric sample and dry it naturally.

[0011] Preferably, the water bath temperature in S2 is maintained at 80-90°C.

[0012] Preferably, 5 to 10 g / L of NaOH and NaCl are added to S3.

[0013] Preferably, the total immersion and stirring time in S3 is 1 to 2 hours.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The present invention uses natural dyes obtained from ginseng fruit pulp, which are environmentally friendly and non-toxic, and can avoid the release of a large amount of harmful substances during the production and use of traditional chemical dyes, which helps to reduce environmental pollution. In addition, ginseng fruit is a nutritious and high-yield fruit. By rationally utilizing its pulp, the added value of the fruit can be increased, promoting the development of the agricultural economy and the income of fruit farmers.

[0016] (2) The ginseng fruit used in the present invention is a renewable natural resource, and the prepared natural dye is also renewable and can be produced continuously for a long time, thereby ensuring the stability and sustainability of the dye supply. The prepared natural dye has good biodegradability and can be decomposed by the natural environment after use, without causing persistent environmental pollution, and is helpful in maintaining ecological balance.
