Advantages of Plant dye？

1、Non-toxic，non-allergenic and non-carcinogenic to the skin;

2、Good biodegradability and environmental compatibility;

3、The dyed textile is soft and elegent ;

4、Have effect on health care and medicinal value.Green product is popular in our daily life,so plant dye must have a prospective future.

Special functions of plant dye？

1、Anti-bacterial and odor

The plants have the dual effects of dyeing and anti-bacterial. It contains the anti-bacterial active ingredients such as alkaloids, acids, ketones, phenols and citric acid.

2、Anti-UV

The plant structure gives the fabric a good UV absorption or reflection function, which could reduce the UV transmittance.

3、Anti-oxidation

Ellagic acid and polyphenolic compounds are contained in plants.

4、Anti-insect and mildew

Indigo is commonly used by ethnic minorities to resist diseases and sores. Plant-derived fungicides is made from dry distillation liquids such as eucalyptus and maple.

Application 

1、Natural fiber (Wool, Linen,Silk, Cotton)

Most Artificial fiber (Milk fiber, soybean fiber, bamboo fiber, modal, etc.)

2、Textile (Loose fiber, yarn, fabric, garment etc.)

3、Crafts, leather, bamboo and wooden products, cosmetics.Recommended dye dosage<5% (o.w.f).

Dyeing uniformity

1、Macromolecules such as sugar and pectin in plants will affect the affinity of pigments and fabrics.

2、Fabrics or yarns should be fully pre-treated before dyeing, which could ensure uniform color absorption of the fabric.

3、Most of the plant pigments absorb color at normal temperature. plant dye liquor should be slowly added to dyeing bath at room temperature.

Color yield

1、The yield of protein fiber in natural fiber is higher, cellulose fiber is lower and Linen is the lowest.

2、The tightness of the fabric weaving has a significant effect on the color yield,  The fabric is the tighter, the color yield is lower.

3、The bath ratio and pH value will affect the color yield of the fiber.

Dyeing Process

1、The dyeing methods : loose fiber dyeing, yarn dyeing, knitted fabric dyeing, woven fabric dyeing, garment dyeing, tie dyeing, hanging dyeing,

2、We could choose the dyeing method and equipment according to the fabric composition. For silk-linen fabrics, if the silk dyeing process is followed, the linen color yield is less.

3、A variety of process combinations can get more colors. Some plant dyes can not be mixed for color matching, so it is necessary to apply multiple dyeing methods such as counterstaining dyeing.
