Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile auxiliaries, and particularly relates to a novel low-foam scouring agent, a preparation method, application and product thereof. BACKGROUND

[0002] In recent years, the development trend of cotton sales market is good, and there is an increasing demand for the quality of cotton fabrics. The pretreatment process before dyeing and finishing is the basis for ensuring the good quality of cotton products. Cotton yarn needs to be pretreated to achieve good pretreatment effects including moisture absorption, whiteness, strength and hand feeling, which will directly affect the subsequent dyeing process and the quality of the final product. However, with the continuous increase of new product types, the production of cheese dyeing has encountered more and more problems, which has become a problem that cannot be avoided by cheese dyeing processing plants. For example, the problem of cheese inner and outer layer difference.

[0003] The main reason for the cheese inner and outer layer difference is that the pretreatment of cheese is not in place, including the poor penetration of some scouring agents, which can only penetrate the surface of the cheese and cannot enter the inside during pretreatment, and some scouring agents have too much foam, which makes the pretreatment not in place. Traditional scouring and bleaching processes mostly use caustic soda and hydrogen peroxide, which seriously damages the strength of the yarn, and the generated wastewater pollutes the environment, so the scouring agent needs to provide some protection. Therefore, developing a green and environmentally friendly scouring agent with good scouring effect will be the key to solving the problem of cheese inner and outer layer difference.

[0004] CN107653671A provides an environmentally friendly multifunctional scouring agent and a preparation method thereof. The environmentally friendly multifunctional scouring agent provided by the invention does not contain banned substances such as alkyl phenol polyoxyethylene ether and adsorbable organic halides, is easy to dissolve in water, is resistant to acid, alkali and hard water, has low foam, and is easy to use. The environmentally friendly multifunctional scouring agent of the invention integrates penetration, emulsification, chelation, dispersion, and hydrogen peroxide stability, making the pretreatment process simple, reasonable, and economical, and energy-saving and environmentally friendly. It can be widely used in the process of cotton and its blended fabrics, and can be used in conventional desizing / boiling / bleaching process, or short-flow cold piling process, to achieve good desizing rate. However, the invention stabilizes the properties of hydrogen peroxide, but lacks specific data disclosure on the performance indicators such as the strength of textile materials.

[0005] CN111749022A discloses a low-foam high-concentration scouring agent and a preparation method thereof. In the preparation, fatty alcohol polyoxyethylene ether 3EO, fatty alcohol polyoxyethylene ether 5EO, fatty alcohol polyoxyethylene ether 7EO, isomeric tridecanol polyoxyethylene ether, fatty alcohol polyoxyalkyl ether, and an organic solvent are sequentially added to a reactor, and the mixture is stirred uniformly while being heated to 40-50°C. Heating is stopped, and polypropylene glycol antifoaming agent and amide antifoaming agent are sequentially added and stirred uniformly. Then, water and a solubilizer are added, and the mixture is stirred uniformly and filtered. The scouring agent has high concentration, low foam, transparent appearance, stable storage, low transportation cost, and small addition amount during use. The fabric treated by the scouring agent has good whiteness, capillary effect, strength, and no oil spots. The preparation method of the scouring agent is also provided. However, the whiteness level of the scouring agent is still not ideal, and the scouring agent is difficult to be applied to cheese products due to the lack of component compounding and processing for permeability.

[0006] According to the content of CN111749022A, how to provide a low-foam scouring agent is one of the problems to be solved in the field.

[0063] Comparative Example 2 A novel low-foam scouring agent and a preparation method thereof

[0064] The difference between this comparative example and Example 1 is only that the raw materials and their amounts used are different, specifically:

[0065] Isomeric alcohol ether carboxylate (AEC-1107) 28 parts, fatty acid methyl ester ethoxylate sulfonate (FMES) 10 parts, isomeric alcohol polyoxyethylene ether 17 parts, glacial acetic acid 20 parts, sodium secondary alkyl sulfonate (SAS) 26 parts, sodium dodecyl benzene sulfonate (LAS) 16 parts, defoamer 3 parts and antibacterial agent 3 parts.

[0066] A novel low-foaming scouring agent and a preparation method thereof

[0067] The difference between the present comparative example and Example 1 is only that different raw materials and amounts are used, specifically:

[0068] Only isomeric alcohol ether carboxylate (AEC-1107) 20 parts is replaced by isomeric C10 alcohol polyoxyethylene ether carboxylate sodium (AEC-10) 25 parts.

[0069] Test Example 1: Test of different scouring agent impregnated scouring and bleaching fabric effect:

[0070] Formulation: NaOH 2 g / L + H2O2(100%) 2 g / L + the type and amount of scouring agent as shown in Table 1;

[0071] Fabric: 20x16 / 128x60 raw fabric 5 g + all-cotton knitted fabric 5 g;

[0072] Bath ratio: 1:10;

[0073] Steel beads: 10 per cup;

[0074] Process: 1.5℃ / min temperature rise→98℃ for 60 min→test fabric effect

[0075] The specific method for testing the fabric effect is:

[0076] Cut 20*2.5 cm (weft* warp) fabric samples on the fabric to be tested, and make sure that the starting end of the climb is in the middle of the fabric strip; test the 30-minute 0.2% potassium dichromate solution climb height, if the climb height is uneven, draw the climb interface and take a photo, and at the same time, record the fabric effect (unit: cm) at the lowest point, and the average value of the results of different fabrics is obtained;

[0077] The results are as follows:

[0078] Table 1: Test results of different scouring agents for scouring and bleaching fabric effect:

[0079]

[0080] As can be seen from the above table, the new low-foaming scouring agent provided by the embodiments 1-5 of the present application has excellent scouring effect, wherein, the comparative examples 1 and 2 use the same raw materials as the comparative example 1, but the raw materials used exceed the range provided by the present application, resulting in unreasonable dosage ratio, so that the boiling and bleaching effect test results of the comparative examples 1 and 2 are significantly worse than that of the embodiment 1, and more prominent under the condition of 0.5 g / L dosage;

[0081] In the comparative example 3, the surfactant isomerol ether carboxylate salt (AEC-1107) used in the present application is replaced, and the dosage is adaptively adjusted. However, according to the test results in Table 1, after replacing the surfactant, the performance of the comparative example 3 decreases similarly to the comparative examples 1 and 2; this is because the adjustment of the components destroys the synergistic effect between the specific content components, resulting in performance decline;

[0082] As compared with the market samples, the performance of the existing market samples is far inferior to the new low-foaming scouring agent provided by the present application, and even lower than the comparative examples 1-3.

[0083] Test example 2: different scouring agent immersion boiling and bleaching effect whiteness test:

[0084] Formulation: NaOH 2 g / L + H2O2(100%) 2 g / L + scouring agent X g / L;

[0085] Fabric: 20x16 / 128x60 raw cloth 5 g + 100% cotton knitted fabric 5 g;

[0086] Bath ratio: 1:10;

[0087] Steel ball: 10 per cup;

[0088] Process: 1.5℃ / min heating→98℃x60min→test whiteness

[0089] The method for testing whiteness is:

[0090] Use a full-automatic whiteness meter to test five points of the fabric respectively, and record the corresponding Wg value;

[0091] The results are as follows:

[0092] Table 2: different scouring agent boiling and bleaching whiteness test results:

[0093]

[0094] As can be seen from the above table, the fabric boiled and bleached by the new low-foaming scouring agent provided by the embodiments 1-5 of the present application has excellent whiteness, which is significantly better than the comparative examples 1-3 and market samples 1# and 2# under different concentrations.

[0095] Test Example 3: Inner, middle and outer layer whiteness of the cheese

[0096] Formulation: NaOH 3g / L + H2O2(27.5%) 8g / L + scouring agent g / L;

[0097] Fabric: all-cotton cheese;

[0098] Bath ratio: 1:7;

[0099] Process: 2℃ / min→ warming to 60℃ and adding H2O2→ 3℃ / min warming to 110℃→ holding for 30min→ testing whiteness and capillary effect;

[0100] Table 3: Inner, middle and outer layer whiteness and capillary effect of the cheese

[0101]

[0102] As can be seen from the above table, the fabric after boiling and bleaching with the new low-foaming scouring agent provided by the inventive examples 1-5 has excellent inner, middle and outer layer whiteness and capillary effect of the cheese; meanwhile, the whiteness and capillary effect of the inner, middle and outer layers are less different, and have good uniformity; while the comparative examples 1-3 and the market samples 1# and 2# have lower whiteness, and the capillary effect of the inner, middle and outer layers is greatly different; in terms of capillary effect, the capillary effect of the inner, middle and outer layers of the comparative examples 1 and 3 is less different, but the capillary effect is still significantly lower than the new low-foaming scouring agent provided by the inventive examples 1-5.

[0103] Test Example 4: Defatting rate after treatment with different scouring agents

[0104] Formulation: NaOH 2g / L + scouring agent 2g / L;

[0105] Fabric: polyester stained cloth;

[0106] Bath ratio: 1:10;

[0107] Steel balls: 10 per cup;

[0108] Process: 1.5℃ / min warming→ 98℃×40min→ testing defatting rate (referring to AATCC 130)

[0109] Table 4: Defatting rate after treatment with different scouring agents

[0110]

[0111] From the above table, it can be seen that the new low-foaming scouring agent provided by the inventive examples 1-5 has higher degreasing rate after scouring and bleaching, which means that the content of fat and impurities in the fabric is lower, which is beneficial to maintain the strength and flexibility of the fabric; the comparative examples 1-3 and the market sample 2# show lower fabric degreasing rate than the inventive examples 1-5; only the ordinary level in the art; and the degreasing rate of the market sample 1# is only 50%, which is the worst.

[0112] The strength after treatment with different scouring agents in test example 5 is shown in Table 5.

[0113] Formulation: NaOH 3g / L + H2O2(27.5%) 8g / L + scouring agent 2g / L;

[0114] Fabric: 100% cotton cheese;

[0115] Bath ratio: 1:7;

[0116] Process: 2℃ / min→warm up to 60℃ and add H2O2→3℃ / min warm up to 110℃→keep warm for 30min→test strength (refer to national standard GBT 3923.1-2013);

[0117] The strength after treatment with different scouring agents in test example 5 is shown in Table 5.

[0118]

[0119] From the above table, it can be seen that the new low-foaming scouring agent provided by the inventive examples 1-5 has smaller strength loss after scouring and bleaching; at the same time, the strength loss at different temperatures is basically consistent, which can further illustrate that the new low-foaming scouring agent provided by the application can be suitable for various temperatures; although the strength loss of comparative examples 1 and 3 is consistent at different temperatures, the strength loss level is still significantly higher than that of the inventive examples 1-5; the strength loss level and the difference of strength loss at different temperatures of the remaining test groups are worse than those of the inventive examples 1-5.

[0120] Foam situation of different scouring agents in test example 6

[0121] Working liquid treatment: 2g / L of white cat detergent + 0.5g / L of refining agent

[0122] Foam test method:

[0123] Prepare 250ml of working liquid, take 200ml in a burette, install the instrument to the upper end of the graduated cylinder, completely open the stopcock of the burette to make the solution flow vertically, when the solution in the burette flows out, immediately start the stopwatch and read the initial foam height (record the height of the foam peak, if the difference between the high and low points of the foam is too large, record the two data of the highest and lowest points), record the foam height at 10, 30, 60, 120, 180, 300 seconds.

[0124] Table 6 Different scouring agent foam situation:

[0125]

[0126] From the above table, it can be seen that the new low-foaming scouring agent provided by embodiments 1-5 of the present application has extremely fast defoaming speed; since foam can cause problems such as spots and defects on the fabric, the new low-foaming scouring agent provided by the present application can effectively reduce the generation of fabric spots and defects; Comparative Example 1 needs more than 60s to completely defoam due to the adjustment of the amount of components, even with up to 9 parts of defoaming agent; which is significantly higher than the foam amount of the new low-foaming scouring agent provided by the present application; although Comparative Example 3 shows fast defoaming speed and can complete defoaming within 60s, its foam amount is also significantly higher than that of the new low-foaming scouring agent in the embodiments of the present application.

[0127] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical solutions of the present application made by ordinary skilled in the art do not deviate from the essence and scope of the technical solutions of the present application.
