Dyed Textile Products

Abstract

A Dyed textile article including raw fiber, yarn, woven fabrics, knitted fabrics, non-woven fabrics pre-treated with natural components citrus limonum francais, sapindus mukorossi or acetic acid in the ratio of 1/20 (bleaching agent/weight of cloth); treated with treating component like tannic acid; dyed with the extracts of the herbs wherein the raw fiber, yarn, woven fabrics, knitted/non-woven textile articles is blended with the herbs and; wherein the herbal extract is commingled, stuffed between the raw fibers of the textile article or the yarn and; the said raw fiber/yarn is used for preparing textile articles wherein the said raw fiber is carefully and hygienically stuffed in between the layers of textile articles; wherein the said raw fiber/yarn is capable of providing health benefits along with feel and hue of the naturally dyed textile articles.

Stuffing or comingling the herbs to make the pads used for various purposes. The method is in use for quite long, but advancement of using the technique for making hair cleanser/conditioner/scrub/washing of clothes and dishes, is an inventive step.

Potential use of the herbs for various purposes as cleaning, washing has been observed to be increased 3-4 times than the conventional method of use for same purpose. For example, 30 grams of herb is used to give result of 90 to 120 grams. Using the herb in this manner is advancement over previous conventional methods in water conservation as well as herbs conservation.

This technology makes the use of 100% herbs naturally with simple procedure and directly without any chemical process or preservatives and enhances the efficiency, yet comfortably (without creating mess in the use area). The herb is used as pad with natural cover.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0020] 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.

[0021] 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).

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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

[0026] 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:

[0027] Formulation for Yellow Color: [0028] 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.

[0029] Formulation for Red Color:

[0030] 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:

[0031] 50%-100% of the extract of Neem/wt. of fabric. The extract of this herb is useful for skin and acts as an antiseptic. [0032] 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. [0033] Both of these herbs can also be used in equal proportions to have effects of both the herbs.

[0034] Formulation for Brown Color: [0035] 50%-100% of extract of Ajwain/wt. of fabric. The extract of this herb is useful in cough, indigestion and liver problems.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Thus the textile article or the further articles made of these textile articles can be used for various healing purposes.

[0042] In one of the embodiment aroma of some herbs like jasmine, tulsi, sehdei, sandal, devdar is being utilized for producing the textile articles.

[0043] 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.

[0044] 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.

[0045] 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.
