Benefits of technology

The present invention is about a textile material that dries quickly. It is made by coating the textile with a special substance that absorbs near infrared energy. The method for making this material involves treating the textile with the coating and then processing it to make a quick dry textile material. The use of this coating results in a more efficient drying process for the textile material.

Problems solved by technology

However, all these techniques are limited to the transfer of moisture from skin touching fabric surface to outer fabric surface.

example 1

[0135]Scoured and bleached cotton fabric samples having 5 g of weight are used in the dyeing process. The fabric GSM (grams per square metre) is 170 grams per square meter and the structure is single jersey. The fabric samples are charged in to a sample dyeing container with 3000 ml of water having 1:15 material to liquor ratio (200 g of fabric) and Indium tin oxide nanoparticles having diameter in the range of 10-40 nm having a weight of 5% on weight of the fabric is also added to the solution. The dyeing capsule temperature is increased gradually up to 80° C. with a rate of 2° C. / minute. The temperature is maintained at 80° C. for 45 minutes and upon completion, slowly cooled down to the room temperature (25° C.). The fabric sample is taken out of the container, washed with water and dried (under 105° C. for 10 min). The AATCC Test Method 201-2013, Drying Rate of Fabrics: Heated Plate Method is used to analyze the drying rate performance. Untreated fabric shows an average drying r...

example 2

[0136]The same procedure as given in Example 1 is repeated with a change in textile substrate. The textile substrate or fabric used in example 2 is 1×1 rib fabric of cotton having a weight of 162 gram per square meter. The treatment of the fabric is similar to Example 1. The treated fabric is analyzed for the drying rate performance by AATCC Test Method 201-2013, Drying Rate of Fabrics: Heated Plate Method. Untreated fabric shows an average drying rate of 0.99 ml / h. Average drying rate of the treated fabric is 1.57 ml / h. The treated fabric sample thus shows a drying rate improvement of 58±4% compared to the untreated fabric.

example 3

[0137]The same procedure as given in Example 2 is repeated with a change in NIR energy absorbing agent. In this example, a weight of 5.0% on weight of the fabric, of 70:30 mixture of Aluminum doped zinc oxide and Indium tin oxide is used. The treatment of the fabric is similar to Example 1. The treated fabric is analyzed for the drying rate performance by AATCC Test Method 201-2013, Drying Rate of Fabrics: Heated Plate Method. Untreated fabric shows an average drying rate of 1.62 ml / h. Average drying rate of the treated fabric is 2.36 ml / h. The treated fabric sample thus shows a drying rate improvement of 46±8% compared to the untreated fabric.

Abstract

The present invention relates to production of textile with high rate of evaporation of moisture content. In this invention, a textile substrate is coated with Near Infrared (NIR) energy absorbing agent to increase the surface temperature of substrate and enhance the evaporation of moisture from the textile substrate.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to the field of textile industry in general, specifically to textile finishes and moisture management. In the present invention, the textile substrate is treated with a composition comprising near infrared energy absorbing agent that provides faster drying of moisture content from the treated textile, leading to quick drying textile material. The present invention relates to the quick drying textile material, a method to obtain the textile material and use of a composition comprising near infrared energy absorbing agent to obtain the textile material.BACKGROUND[0002]Moisture management generally refers to the ability of the textile material to absorb gaseous or liquid moisture from body, to transport it to the outer surface and to evaporate the moisture content. This property is a complex combination of a number of different human, material and environmental aspects. Given the same conditions, rate and intensity of ...
