FIELD OF INVENTION

The present invention relates to dyed textile articles which have a natural color tone and a natural feeling, deep and fast shades and have antimicrobial and anti allergic properties. The invention further relates to a method of producing such articles.

BACKGROUND OF THE INVENTION

Use of the natural colors for dyeing i.e. herbal dying is known since long. The use of natural colors for dyeing has seen a decline in the past with the use of more cost effective synthetic dyes which can give varied colors. However, because of the unique and exquisite characteristics of the natural colors they have again been receiving due recognition in recent years as is shown by general trends towards favoring naturalness.
The term “herbal dyeing” means dyeing with plant-derived coloring materials. The majority of natural colors are of vegetable origin. However, sometimes colors from animal dyes, such as cochineal and purple of the ancients (secretions of Murex brandaris, a sea snail) and mineral dyes, such as Berlin (Prussian) blue, is sometimes referred to as herbal dyes.
A great detail of the natural colors applicable to herbal dyeing is available in the U.S. Pat. No. 5,880,044, WO2004072182A2 etc. which include coloring matters available from a large variety of plants such as Carthamustinctorius (safflower), Sophora japonica (Japanese pogada tree), Uncariagambir (gambir), Prunusmume (Japanese apricot), cherry tree, Punicagranatum (pomegranate), Theasinensis (tea), Ternstoremiagymnanthera (evergreen tree), Rubiacordifolia (madder), Caesalpiniasappan (sappan wood), lithospermum, Rhusjavanica (Japanese sumac), Eurya japonica, Artemisia princeps (wormwood), Miscanthussinensis (eulalia), Chrysanthemum morifolium var. sinense (Chinese chrysanthemum) etc. Further, there are several disclosures where use of the microorganisms such as fungi, algae has been proposed as a dyestuff.
Japanese Patent Kokai Publication No. 132886/1989 describes a method of dyeing a textile article which comprises dispersing a microfine powder of quartz porphyry in a water-soluble acrylic resin solution, pouring the dispersion in hot water, adding a plant extract and a dyestuff thereto, dipping a substrate textile product in the resulting dye bath and carrying out the usual after-treatments such as soaping and drying.
In the conventional herbal dyeing the process is not only complicated but has inferior dye reception and color fastness, particularly in the case of cotton and linen, resulting in the fact that the unique characteristic of the coloring substance is not lasting and this has been the greatest disadvantage of herbal dyeing.
The present invention has been developed, against the above background, to provide a dyed textile article having the natural and unique hue and feeling and having antimicrobial and anti-allergic activities.
The present invention also relates to dyed textile articles having healing properties wherein the raw fibre of the textile article is dyed with the herbal extract and is stuffed between the layers of the herbally dyed textile articles in the desired shapes.
Ayurveda uses various methods and material to heal. One of the common material that is used for healing is herbs. Herbs as name signifies are of plant kingdom. Stem, leaves, bark, root, fruit, flower are used externally or internally as properties and requirement. Some herbs through aroma, others through intake or touch, help in healing. Ayurveda works on the principle of enhancing and nourishing natural healing powers. It supports the maintenance of natural health as well curing through illnesses. Illness could be mental or physical illness.
Various traditional herbs are known for healing through touch, smell are used for dying, mixing with cotton, wool and stuffing in clothes (quilting), pillows, mattresses and clothes to support health and healing for normal health conditions.
Thus one aim of this invention is to support and disseminate the healing through the use of Ayurveda in modern societies where the true benefits of Ayurveda have been long forgotten and the life is filled with chemical products either during the healthy times or during the time when one is sick.
Another aim of the invention is to imbibe the benefits of Ayurveda in the daily life in more effective and simple ways. For example, our skin has a property to absorb and we in the usual manner try to coat it with chemicals which may be harmful. In one of the embodiments of the invention, the cotton yarn dyed and stuffed with the herbal extract can be a good option for healthy living conditions.

SUMMARY OF THE INVENTION

The dyed textile article according to the present invention is prepared using organic cotton yarn, wherein the raw fibre, yarn and the resulting fabric is dyed and mixed with the predetermined herb to support a particular health or health conditions.
In another embodiment of the invention, the herbs are blended in the yarn itself as compared to the option of dyeing the textile article, since herbs and their extracts are lost through frequent washings where as stuffed and blended yarns can have a higher potency through various methods like wetting, infusion of steam etc.
In yet another embodiment of the invention, the textile article is prepared by carefully inserting the raw fibre commingled with the herbal extract, between the layers of textile articles already dyed with the herbal extract. The herbal extracts are blended and stuffed in the fibre yarn as compared to the option of dyeing the textile article. In such articles, higher potency of the effects of herbs can be achieved through various methods like wetting, steaming etc. Further, the loss of the herbal extracts are reduced as compared to the herbal dyed textile articles, in these stuffed articles as hereinbefore described, since the herbal extracts are intermingled with the fibre yarn and the loss of the herbal extracts are greatly reduced during frequent washing/drying of the textile article.
The present invention also provides for the method of producing such dyed textile articles wherein the article to be dyed is put in a bath having the extract of the dye, which has been prepared by grinding the said herb. Further, the present invention also provides for the method of producing such textile articles wherein the herbs are blended and stuffed in the yarn so that the yarn retains the properties of herb even after several washings.

DETAILED DESCRIPTION OF THE INVENTION

The dyed textile article according to the invention can be any and all the raw fibers, yarns woven fabrics, knitted fabrics, nonwoven fabrics etc. The raw materials for such textile articles are not limited to but include cotton, linen, wool, silk etc. However, the invention lays emphasis on the cotton yarn which can be dyed, blended with the and also stuffed with the herbs.
In accordance with the present invention, raw fibre, the yarn or the article to be dyed is bleached, pretreated and then contacted with a pre-treating bath. Bleaching is done with natural components like lemon water, reetha or vinegar in the ratio of 1/20 (bleaching agent/weight of cloth).
The bath ratio for pretreatment is about 10 to 100 times (particularly about 20 to 60 times) based on the weight of the textile article. The bath temperature is about 50° to 95° C. Preferably between 55° C. to 70° C., and the treating time is about 2 hrs. The concentration of tannic acid is usually about 5% by weight based on the weight of the textile product, although the range is not exclusive.
After performing the acid pre-treatment the textile article is contacted with a mordant bath containing alumina or sea salt for mordanting. The process of mordanting is very important and unless it is carried out, both dyeing affinity and fastness of color will not be upto the mark in the next dyeing stage.
Sea salt is most commonly used mordant because some herbs like turmeric changes color with alumina and wherever the change in color is required, alumina is used. After bleaching the cloth, the mordanting is done by mixing the mordant in 1/20 ratio (mordant/water) in normal water while dipping the cloth in mixture for 1 hour.
The mordant bath ratio is about 1:10 to 1:100 (particularly 1:20 to 1:60). The bath temperature may range from ordinary temperature to boiling temperature, the treating time is about 10 minutes to 1 hour, and the concentration of the alumina mordant is usually about 3 to 15% by weight, as aluminum ion, although these ranges are not critical
After said pre-treatment and mordanting, the textile article is dyed by contacting it with a dye bath containing an extract of the desired herb having the desired properties. It is important to note that the dyeing should not precede the acid treatment and mordanting. If mordanting is performed after dyeing, the desired effect will not be upto the mark. Various formulations for herbal dyes are given below:
Formulation for Yellow Color:

- 50%-100% of turmeric extract/wt. of fabric. The turmeric extract is useful for various skin and liver disorders. The extract can be utilised in different ratios depending on the requirements.

Formulation for Red Color:
50%-100% of the extract of Rattan Jyot/wt. of fabric. If pink color is required, the herb is used in moderation. The extract of this herb is useful in skin diseases and as a blood purifying agent.

Formulation of Green Color:

- 50%-100% of the extract of Neem/wt. of fabric. The extract of this herb is useful for skin and acts as an antiseptic.
- 50%-100% of the extract of tulsi/wt. fabric. The extract of this herb is useful for cough and cold and it also acts as an anti-viral agent.
- Both of these herbs can also be used in equal proportions to have effects of both the herbs.

Formulation for Brown Color:

- 50%-100% of extract of Ajwain/wt. of fabric. The extract of this herb is useful in cough, indigestion and liver problems.

By combination of the above colors, many other shades/colors can be obtained. Further many other extracts from different herbs can be utilised for getting a particular color.
The required dye is extracted from the herbs by soaking the herbs in water wherein the quantity of water is about 15 to 20 times the wt. of herbs. The solution is boiled at 90° C. for about 1.5 hrs-2 hrs. The solution thus prepared is kept overnight. It is then strained through cloth to avoid unwanted dyes & bigger particles of herbs or any other particles. The strained solution is now ready as herbal dye solution. In preparing dye solution of turmeric the method is same as above but the temperature should be maintained at 60° C.
The bath ratio for dyeing reaction is generally about 10-100 times and the bath temperature is about 50 to 95° C. The treating time is generally kept about minimum of 30 minutes to about a maximum of 180 minutes. The concentration of the dye can be selected according to the type of the article, type of the herb and also the size of the article to be dyed.
After the dyeing process is completed, the article is subjected to the standard after treatment such as cleaning, washing, rinsing and drying. The resulting textile article is thus a herbal dyed article with a herbal healing quality. It is to be noted that no soap is used for cleaning. However, the article is rinsed with water at high temperatures to obtain proper sanitization.
The dyeing of the textile article with the herbal extract having an active ingredient, imparts to the textile the healing properties such as anti allergic properties, antimicrobial properties etc.
Thus the textile article or the further articles made of these textile articles can be used for various healing purposes.
In one of the embodiment aroma of some herbs like jasmine, tulsi, sehdei, sandal, devdar is being utilized for producing the textile articles.
In one of the further embodiments of the invention, the wearable clothes such as diapers etc. used by the healthy infants as well as adults having some medical conditions are made with the raw fibre dyed with the herbal extract and stuffed in between the layers of the textile article. Further, customized clothing for particular health conditions can be prepared with the appropriate herbs.
In yet another embodiment of the invention, the gynecological problems can be treated using the textile articles stuffed with the extract of the particular herbs.
In yet another embodiment of the invention, the pillows, mattresses, breast pads, quilts, napkins etc. are stuffed with organic cotton fibre or any other raw textile fibre which are processed and dyed with herbs which helps in various health conditions and helps maintain healthy life.
