Description
Technical Field
The invention relates to a low-temperature bleaching detergent composition for cotton fabrics, a preparation method and application thereof, belonging to the field of household washing.
Background
In daily life, textiles, especially white textiles, are easily stained with colored stains, so that the appearance of the textiles is seriously affected, and therefore, in the washing process, the color substances contained in the fiber materials, the textiles and the like need to be removed by a chemical bleaching method, so that the whitening effect is achieved. The bleaches currently used in the whitening wash of textiles are mainly chlorine bleaches and hydrogen peroxide and its derivatives.
The chlorine-containing bleaching agent cannot be mixed with the cleaning agent containing ammonia during the use process; chlorine bleaches cannot be used to clean up urine stains either because toxic chloramine and explosive nitrogen trichloride are produced; chlorine-containing bleaches cannot be mixed with toilet cleaners because this produces toxic chlorine, which not only causes pollution of the water and harm to human health, but also causes severe damage to textiles and also causes corrosion to human skin. And therefore have certain limitations in the white washing of textiles.
The hydrogen peroxide and the derivatives thereof are mainly decomposed into oxygen and water in the using process, and are safe and clean bleaching agents, so the application development in the whitening washing of textiles is quicker. Peroxides such as sodium perborate, sodium percarbonate, carbamide peroxide, etc. are hydrogen peroxide derivatives that release hydrogen peroxide in aqueous solutions and effectively remove colored stains on textiles under alkaline (pH > 10) and high temperature (not lower than 80 ℃), and are therefore commonly used as the main ingredient for white washing of textiles. However, since the home laundering temperature is much lower than the effective temperature of these peroxides, the development of low temperature whitening laundering techniques for textiles has become an important issue facing the home laundering industry.
The bleaching activator is an organic peroxyacid precursor, and can react with hydrogen peroxide released by peroxide in an aqueous solution to generate more active organic peroxyacid, so that colored stains on textiles can be effectively removed at a lower temperature. Two of the more commonly used bleach activators in current household detergents are Tetraacetylethylenediamine (TAED) and sodium Nonanoyloxybenzenesulfonate (NOBS).
Tetraacetylethylenediamine (TAED) is used in combination with sodium perborate or sodium percarbonate as an oxide bleaching system in washing processes, and the peracetic acid anion generated after their reaction in water is the main bleaching agent in the system, and plays a role in whitening, stain removal and antimicrobial. However, at water temperatures below 60 ℃, perborate or percarbonate alone cannot exert a bleaching effect, and thus TAED is required to exert a bleaching effect. In short, at water temperatures below 60 ℃, the bleaching detergent requires the addition of TAED; TAED cannot be used alone, and must be used in combination with perborate or percarbonate. Under the alkaline condition, 1 mol of TAED reacts with 2 mol of perhydroxide anions to generate 1 mol of DAED and 2 mol of peracetic acid anions, and the TAED and the DAED are immediately biodegraded and are nontoxic; peracetic acid anion is used for bleaching and sterilizing.
The nonanoyloxy benzene sulfonic acid sodium (NOBS) is a second-generation bleaching activator, belongs to a low-temperature bleaching activator with lower oxygen-release activation energy, and generates peroxycarboxylic acid with bleaching capacity obviously stronger than that of hydrogen peroxide by reacting with hydrogen peroxide anions in a bleaching system, so that the system has better low-temperature bleaching capacity. Meanwhile, NOBS is a high-efficiency low-temperature bleaching activator, can achieve the bleaching promoting effect to the maximum extent under the condition of extremely small addition amount, and is widely applied to the fields of washing, papermaking, spinning, printing and dyeing and the like.
However, these two bleach activators are only effective at temperatures between 40 ℃ and 60 ℃ and have found widespread use in countries with higher home laundering temperatures. However, domestic washing of textiles in China and some countries is usually carried out at room temperature (25 ℃), and the physical and chemical properties of the existing bleaching activators cannot meet the requirements.

As can be seen from table 2: the whiteness of the white cotton fabrics polluted by different cotton fabric low-temperature bleaching detergent compositions is different and greatly different after the white cotton fabrics are treated by the detergent compositions. The whiteness values of the fabrics treated by the sodium dodecyl benzene sulfonate, the sodium percarbonate and the TBLC (formulas 1, 2 and 3) are low and the color difference is large, which indicates that coffee stains can not be completely removed by the sodium dodecyl benzene sulfonate, the sodium percarbonate and the TBLC; when the fabric is washed by the sodium dodecyl benzene sulfonate, the sodium percarbonate and the TBLC (formula 4, 5 and 6) detergent, the whiteness cannot be recovered to the level before being polluted, and the color difference with the original uncontaminated cloth is larger. Only the whiteness of the white pure cotton woven fabric treated by the composition of sodium dodecyl benzene sulfonate, sodium percarbonate and TBLC is close to the whiteness of the uncontaminated white pure cotton woven fabric, and the rinsing effect is good, so that the three components of the composition have a synergistic bleaching effect, the performance of the cotton fabric is basically not influenced, and the moisture absorption and the softness of the fabric are improved.
Example 2
A cotton fabric low-temperature bleaching detergent composition comprises sodium dodecyl benzene sulfonate, sodium percarbonate solid, N- [4- (N, N-dimethyl dodecyl ammonium methylene) benzoyl ] caprolactam chloride (TBLC) and water, and the specific dosage is as shown in Table 3:
TABLE 3 formulation of different detergents
| Formulation of | Sodium dodecyl benzene sulfonate (g/L) | Sodium percarbonate (g/L) | TBLC(g/L) |
| Formulation 7 | 1 | 0.75 | 2.5 |
| Formulation 8 | 1 | 0.75 | 0.63 |
| Formulation 9 | 1 | 0.75 | 1.25 |
| Formulation 10 | 1 | 0.5 | 2.5 |
| Formulation 11 | 1 | 1 | 2.5 |
Adding 30g of coffee into 300mL of 100 ℃ water, and uniformly mixing to obtain a coffee solution; and then soaking 30g of white pure cotton woven fabric in coffee solution for 5min, taking out, washing with water and naturally drying to obtain the cotton fabric to be rinsed.
Placing the cotton fabrics to be rinsed in the low-temperature bleaching detergent compositions in the table 3 at normal temperature (25 ℃) respectively, washing for 30min by using a household washing machine, taking out, drying and testing the performance of the cotton fabrics.
The test results are given in table 4 below:
table 4 test results after treating coffee stained cloths with different formulations
| Index (I) | Original cloth | Coffee stained cloth | Formulation 7 | Formulation 8 | Formulation 9 | Formulation 10 | Formulation 11 |
| Whiteness (CIE WI) | 77.41 | 16.16 | 75.07 | 48.65 | 60.35 | 66.93 | 76.38 |
| Color difference (CMC delta E) | 0 | 10.56 | 0.46 | 6.55 | 4..92 | 5.98 | 0.42 |
| Strength (N) | 491.69 | 470.56 | 478.65 | 458.56 | 469.85 | 464.85 | 456.32 |
| Moisture regain (%) | 6.91 | 6.5 | 8.87 | 7.86 | 7.12 | 7.89 | 7.64 |
| Softness | 67.54 | 63.65 | 71.66 | 68.67 | 69.89 | 68.52 | 67.45 |
As can be seen from table 4: the whiteness of the white cotton woven fabric polluted by the treatment according to different proportions of the formula 7 is different but not very different. When the TBLC bleaching agent is used at a low concentration (formulas 8 and 9), the detergent has certain detergency, but coffee stains cannot be completely removed, and an ideal detergent effect cannot be achieved. The use of sodium percarbonate at lower concentrations (formula 10) resulted in detergency, but the detergency was not as good as that of formula 7. The whiteness of the white pure cotton woven fabric treated by the formula 7 is close to the whiteness of the white pure cotton woven fabric without pollution, the rinsing effect is good, and meanwhile, the moisture absorption and softness of the fabric are improved.
Example 3
Adding 30g of coffee into 300mL of 100 ℃ water, and uniformly mixing to obtain a coffee solution; and then soaking 30g of pure cotton white woven fabric in coffee solution for 5min, taking out, washing with water and naturally airing to obtain the cotton fabric to be rinsed.
Placing the cotton fabrics to be rinsed in the detergents shown in the table 5 respectively at normal temperature (25 ℃), washing the cotton fabrics for 30min by a household washing machine, taking out the cotton fabrics, drying and testing the performance of the cotton fabrics.
The test results are given in table 5 below:

Note: formulation 7 is the formulation 7 mentioned in examples 1 and 2, the usual detergents 1 and 2 are commercially available detergents which are usually used for washing coffee stains, and the addition concentration of the active ingredient is 15g/L.
As can be seen from table 5: the fabric treated with the combination of sodium dodecylbenzenesulfonate, sodium percarbonate, TBLC (formula 7) had better whiteness values, while neither of the two detergents sold on the market had the ability to treat coffee stains and the whiteness could not be restored to the level before staining.
Example 4
Adding 30g of coffee into 300mL of 100 ℃ water, and uniformly mixing to obtain a coffee solution; and then soaking 30g of white pure cotton woven fabric in the coffee solution for 5min, taking out, washing with water and naturally drying to obtain the cotton fabric to be washed and bleached.

| Softness | 67.54 | 63.65 | 71.66 | 67.46 | 68.21 |
As can be seen from table 7: the fabric treated with the combination of sodium dodecylbenzenesulfonate, sodium percarbonate, TBLC (formulation 7) had a better whiteness value; the whiteness of the white pure cotton woven fabric treated by the composition of the sodium dodecyl benzene sulfonate, the sodium percarbonate and the sodium nonanoyloxy benzene sulfonate (formula 12) is improved to a certain extent, but is not close to the whiteness of the white pure cotton woven fabric without pollution, while the rinsing effect of the composition of the tetraacetylethylenediamine (formula 13) is the worst, the TAED is hardly dissolved at room temperature (25 ℃), and the bleaching effect is poor.
Example 5
A cotton fabric low-temperature bleaching detergent composition comprises sodium dodecyl benzene sulfonate, sodium percarbonate solid, N- [4- (N, N-dimethyl dodecyl ammonium methylene) benzoyl ] caprolactam chloride (TBLC) and water; wherein the concentration of sodium dodecylbenzenesulfonate is 1g/L, the concentration of sodium percarbonate solid is 0.75g/L, and the concentration of N- [4- (N, N-dimethyldodecylammoniummethylene) benzoyl ] caprolactam chloride (TBLC) is 2.5g/L (formula 7).
Adding 30g of coffee into 300mL of 100 ℃ water, and uniformly mixing to obtain a coffee solution; and then soaking 30g of white pure cotton woven fabric in coffee solution for 5min, taking out, washing with water and naturally airing to obtain the cotton fabric to be rinsed.
Placing the cotton fabric to be rinsed in the formula 7 at the temperature of 10, 25, 30, 35 and 40 ℃ respectively, washing for 30min by using a household washing machine, taking out, drying and testing the performance of the cotton fabric.
The test results are given in table 8 below:
TABLE 8 test results at different washing temperatures
| Index (es) | Original cloth | Coffee stained cloth | 10℃ | 25℃ | 30℃ | 35℃ | 40℃ |
| Whiteness (CIE WI) | 77.41 | 16.16 | 50.36 | 75.07 | 76.5 | 77.89 | 80.02 |
| Color difference (CMC delta E) | 0 | 10.56 | 7.89 | 0.46 | 0.32 | 0.11 | 0.36 |
| Strength (N) | 491.69 | 470.56 | 480.62 | 478.65 | 469.56 | 456.8 | 446.49 |
| Moisture regain (%) | 6.91 | 6.5 | 7.69 | 8.87 | 8.33 | 8.57 | 8.69 |
| Softness | 67.54 | 63.65 | 67.69 | 71.66 | 69.29 | 70.53 | 72.62 |
As can be seen from table 8: bleaching with the TBLC combination is less effective at very low temperatures, and is excellent and comparable at normal and higher temperatures. The composition has a good bleaching effect at room temperature, can be bleached to be close to the whiteness of an uncontaminated white pure cotton woven fabric, and has a good bleaching effect. The bleaching effect is increased along with the increase of the temperature, and the whiteness of the bleached cotton fabric polluted at 40 ℃ is higher than the original whiteness of the fabric, which shows that the bleaching effect on the original impurities of the cotton fabric is realized.
Example 6
Adding 30g of coffee into 300mL of 100 ℃ water, and uniformly mixing to obtain a coffee solution; then, 30g of red pure cotton woven fabric (cotton fabric dyed by red reactive dye) is soaked in coffee solution for 5min, taken out, washed by water and naturally dried to obtain the cotton fabric to be rinsed.
