Definitions
- the present invention relates to the field of textiles, in particular to a process for producing treated textile articles and to textiles articles obtained through the process.
- the process of the invention increases opacity of textile articles.
- the present invention also relates to compositions that are suitable to impart opacity to textiles to which they are applied, and that are suitable to be used in the mentioned process.
- white garments generally reveal the colour of the skin and/or the colour and the shape of the underwear of the user when the garments are worn.
- titanium dioxide is provided to fabrics to impart anti-UV, antibacterial and self-cleaning properties. It is also known to apply titanium dioxide or a composition containing T1O2 to fabrics to obtain opaque white garments.
- KR910006104(B1 ) discloses a process for the preparation of an opaque fibre textile.
- a fabric which is composed of polyester filament yarns is impregnated with a solution composed of titanium dioxide 4-7% and dispersing agent 0.1 - 0.5% by weight of treated fabric. Titanium dioxide has particle diameter 0.1 - 0.4 pm.
- the solution is applied by impregnation for 20-30 minutes, and fixed to the fabric.
- the treated fabric is then coated with a transparent resin, where the main component is diisocyanate.
- the process disclosed in KR910006104(B1 ) requires two separate steps, i.e. , a step of impregnation of the fabric with the titanium dioxide, and a second step of coating with resin. Therefore, the process disclosed in KR910006104(B1 ) is a complex manufacturing process which, additionally, requires long working time. Moreover, the resin coating, which covers the titanium dioxide, may provide an unpleasant aesthetical appearance to the fabric, and thus to the garments comprising it.
- GB2051163 discloses a method of preparing an opaque fabric by increasing its covering power with T1O2 .
- Still another aim of the present invention is to provide a process which allows to increase the whiteness of fabrics.
- a further aim of the present invention is to provide a fabric which is white or has a light colour and substantially hides the skin and body of the user, or hides the colour and shape of his underwear, when a garment including said fabric is worn by the user.
- Another object of the present invention is a fabric according to claim 17.
- Still further objects of the present invention are a garment according to claim 23, comprising the said treated fabric, an aqueous composition according to claim 24, and the use of said composition in the process of the invention, according to claim 26.
- Figure 1A and Figure 1 B are photographs showing a sample fabric before (Figure 1 A) and after ( Figure 1 B) the process of the invention.
- Figure 2A and Figure 2B are magnified photos at 10X that show a sample fabric before (Figure 2A) and after ( Figure 2B) the process of the invention.
- Figure 3A and Figure 3B are photographs taken at magnification of 60X that show a sample fabric before (Figure 3A) and after ( Figure 3B) the process of the invention.
- an object of the present invention is a process for producing a treated fabric, comprising the step of:
- aqueous composition comprising titanium dioxide and at least a binder, preferably a crosslinkable binder, and

- Opacity and CMC DE color difference
- the fabric was treated to obtain the “Treated fabric 1”, the “Treated fabric 3” and the“Treated fabric 4” according to Example 2.
- Opacity and CMC DE were measured spectrophotometrically, according to methods which are known per se, using white and black background cards, by Datacolor 600 spectrophotometer. Opacity of fabrics was measured, on paper backing, as the ratio expressed as a percentage, of the single-sheet luminous reflectance factor, Ro, to the intrinsic luminous reflectance factor, R , of the same sample, according to the formula:
- the single-sheet luminous reflectance factor,“Ro” is defined as the luminous reflectance factor of a single sheet of fabric with a black cavity as backing.
- the intrinsic luminous reflectance factor, “R” is defined as the luminous reflectance factor of a layer or pad of fabric which have a thickness such that a further increase in the thickness of the layer or pad results in no change in the measured reflectance factor.
- the single sheet of fabric is a single fabric when it is not folded, so that the thickness of the layer or pad above mention corresponds to the thickness of a single fabric.
- the thickness of the layer or pad may be increased, for example, by folding the fabric so that two or more portion of the same fabric are the superimposed in order to increase the thickness of the layer or pad to be analyzed, up to a thickness which provides for a reflectance factor value which does not changes if the thickness of the layer or pad is further increased.
- CMC DE is the difference between a sample color and a reference color.
- CMC DE was measured using white and black background cards, by Datacolor 600 spectrophotometer. Firstly, a fabric was placed over white background and reflectance was measured as reference, using Datacolor 600 spectrophotometer. Then, the same fabric was placed over black background and reflectance was measured as sample, using Datacolor 600.
- CMC DE i.e. , color difference
- the process of the invention allowed an increase in the opacity of the fabric of about 8% with respect to the untreated fabric. Also, the process of the invention allowed a reduction of the CMC DE (i.e., the color difference) of about 42% with respect to the untreated fabric.
- the process of the invention allowed an increase in the opacity of the fabric of about 8,8% with respect to the untreated fabric. Also, the process of the invention allowed a reduction of the CMC DE (i.e., the color difference) of about 40% with respect to the untreated fabric.
- the process of the invention allowed an increase in the opacity of the fabric of about 8,3% with respect to the untreated fabric. Also, the process of the invention allowed a reduction of the CMC DE (i.e., the color difference) of about 39,7% with respect to the untreated fabric.
- Figure 1A and Figure 1 B are photographs showing a sample fabric before (Figure 1 A) and after ( Figure 1 B) the process of the invention.
- Figure 2A and Figure 2B are photographs taken at magnification of 10X and
- Figure 3A and Figure 3B are photographs taken at magnification of 60X.
- the treated fabric of the invention has an improved opacity and whiteness with respect to the untreated fabric.
- Figure 3B particles of titanium dioxide between the fibers and yarns of the treated fabric can be observed. Such particles cannot be observed in Figure 3A, which shows an untreated fabric.
- Figure 3A and Figure 3B show that the present invention is, advantageously, effective in providing titanium dioxide to fabrics.
