ABSTRACT

The worldwide demand for natural dyes is nowadays of great interest due to the increased awareness on therapeutic properties of natural dyes in public. Natural dyes are derived from naturally occurring sources such as plants, insects, animals, and minerals. Several synthetic colorants have been banned because they cause allergy-like symptoms or are carcinogens. Among theall natural dyes,plant- based pigment have wide range of medicinal value.Although known for a long time for dyeing as well as medicinal values.Although known for a long time for dyeing as well as medicinal properties ,the structure and protective properties of natural dyes have been recognized only in the recent past .Many of the plant used for dye extraction are classified as medicinal and some of these have recently been shown to posses remarkable antimicrobial activity. The present review, describes the detail information about medicinal importance found in naturally occurring dye yielding plants, which are helpful to further development of pharmaceutical formulation .

KEYWORDS: Dyes, medicinal value, Dyes, Terry fabric

INTRODUTION

In ancient times, the natural dyes were only used for colouring the fabrics. Natural dyes were used in 2000 years ago and culture exhibits this. Ajantha and Ellora are the examples, which high lights the uses of natural dyes. Most of the natural dyes have great medicinal values too. The medicinal properties of natural dyes are well known in the Indian sub continent for thousands of years. After the innovation of synthetic dyes the natural dyes were replaced by synthetic dyes. Synthetic dyes produce brilliant colours and shades but the waste water and chemicals from the dyeing process ultimately polluted the water, soil and the air. So the use of natural dyes were again concentrated to save the Earth.Nowadays the consumers are aware about their product quality and they are ready to pay more for eco-friendly products. Leading global brands and private labels are increasing their emphasis on eco- friendly textiles.

So the study was planned with the following objective

  1. To study the effect of Natural herbal dyeing on cotton terry fabric.

  2. To study the wearability of Natural herbal dyed cotton terry fabric.

  3. To study the quality of Natural herbal dyed cotton terry fabric colour fastness after 5 and 10 washes.

MATERIAL-HISTORICAL DEVELOPMENT

Originally terry towels were produced on hand looms, but to produce loops, it was necessary to insert long wines in the same way that picks of weft are inserted. After a number of wires had been beaten up by the reed in Lon sequence with the weft, it was necessary to start withdrawing them by hand, to be reinserted thick wires were used to from long loops in the cloth and thinner wires were used for shorter (smaller) loops and ties determined the quality.The principal of terry weaving is thought to have originated in France in 1841, and was first used in the weaving of silk pile cloths. In 1841, john Bright of Rochdale used the terry principal in the weaving of worsted.Credit for the introduction of the terry towel construction as it is known today is often given to Henry Christ, second son of William Miller Chrishy while on the visit to the middle East in the eighteen forties (1848), in Constantinople (Istanbul), he visited Topliapi place of the sultan. During his visit he saw ladies making towels, the texture of which he had not seen before, and obtained the sample of towels. He sent the sample to his brother Richard at his Hill gate mill in stockport, who asked Samuel Holt, the manager of the silk plush weaving department at hill gate mill to produce this structure. Holt obtained a patent Bp (13572, 1851) for, making terry without using wires, the structure and method for producing it were a heady known.

MEDICINAL IMPORTANCE OF HERBAL DYES

The dye process attempts to keep medicinal properties alive on the textile. Dye fixation is accomplished using natural and harmless resource having high medicinal value. This process uses innovative way to standardize the quality and quantity of colour consistently in long running length. Herbal dyeing is applied to textile article like raw fiber, woven fabric, knitted fabric on wove fabric, stitched garment etc. Generally it takes 3-7 days to make the fabric depending upon the application and ailment.

    MEDICINAL PROPERTIES OF CATECHU

    CATECHU 1883: Scudder Catechu is astringent and tonic. It is often used as an alvine astringent in cases of chronic diarrhea and dysentery, unattended with inflammation. In those cases attended with a

    relaxed state of the intestinal exhalants, catechu is an appropriate agent. In these cases it is often associated with prepared chalk, magnesia, opiates, and aromatics, with decided advantage. Its powerful astringent qualities adapt it to the relief of atonic hemorrhages. It is especially useful in immoderate menstruation, for which purpose it may be unite with aromatics and opium.1909: Kings Dispensatory Catechu possesses strong astringent properties. It is used for arresting mucous discharges when excessive, for removing relation or congestion for mucous membranes, and for checking hemorrhages. In chronic diarrhea, chronitc catarrh, colliquativediarhea, and chronic dyssentery, it has proved beneficial especially when combined with opium. As a local application, it is a valuable agent for removing cynancetonsilaris, apthous ulcerations of the mouth, elongation of the uvula, and relaxation and congestion of the mucous membrane of the fuaces, especially of the kind to which public singers are subject; it is also useful in congestion, tenderness, and spongines of the gums, particularly when the result of mercuiralptyalism. Dr.,E.Hopkins states that catechu is not incompatible with opium and quinine, as no presipatate ensues when their respective solutions are united. He recommends, in diarhea, a compound of catechu ten grains, opium one grain, sulphate of quinine two grains, mix, and make into or two powders, according to the urgency of the case. Catechu pallidum has similar properties, but is less astringent it seem to have an especial affinity for the uterus, exerting powerful tonic and alterative influence upon this organ, and has hence been found highly beneficial in many uterine derangements, as in amenorrhea, some forms of dysmenorrhea, menorrhagia, chronic congestion of the uterus, enfeebled uterine nervous system, etc. it is said that the squaws drink a decoction of this plant for several weeks previous to their confinement, for the purpose of rendering parturition safe and easy.

    RESULT AND DISCUSSION

    The results of naturally died fabric has been tested with different laboratory test and statistical analayais has been analaysed by using following test method.

    One-Sample T Test

    The One-Sample T Test procedure tests whether the mean of a single variable differs from a specified constant. Examples. A researcher might want to test whether the average IQ score for a group of students differs from 100. Or a cereal manufacturer can take a sample of boxes from the production line and check whether the mean weight of the samples differs from 1.3 pounds at the 95% confidence level.

    CONCLUSION

    From the study it can be concluded that natural and medicinal value of dyes like indigo, pomegranate peel,Eclipta,Berberry stem, Sappan , Katha can be used for colouring the fabric and the same can serve in ayurvasthraupto ten washes. So this study will be helpful for the creators of ayrvasthra.
