1.1 an end-side epoxysilicone oil was prepared by adding 36.2g of 1, 3-bis (3-glycidyloxypropyl) tetramethyldisiloxane, 23.6g of 3- (2, 3-glycidyloxy) propyltrimethoxysilane and 100g of octamethylcyclotetrasiloxane to a tetramethylammonium hydroxide catalyst and reacting at 100 ℃ for 24 hours,
1.2 adding 200g of polyetheramine M1000 (Henschelman, USA) into a reaction bottle, dropwise adding 80g of the epoxy silicone oil at 80 ℃ for 8-12 hours, and reacting for 3-5 hours after dropwise adding to obtain a compound A;
the preparation method of the compound B comprises the following steps:
2, sequentially adding 100g of laureth-9-carboxylic acid and 51.5g of polyether amine ED410 (American Henschel) into a reaction bottle, introducing nitrogen into the bottom of the reaction bottle at the temperature of 120 ℃, reacting for 5-7 hours, and cooling to obtain a compound B;
and 3, uniformly mixing the compound A, the compound B, glacial acetic acid and water to obtain the finishing agent.
Comparative example 1
A high-permeability finishing agent for woven fabrics comprises, by weight, 35 parts of a compound A, 10 parts of glacial acetic acid and 55 parts of water,
the rest is the same as example 1 and is not specifically described here.
Comparative example 2
A high-permeability finishing agent for woven fabric comprises, by weight, 35 parts of a compound B, 10 parts of glacial acetic acid and 55 parts of water,
the rest is the same as example 1 and is not specifically described here.
The finishing agents obtained in the examples 1-5 and the comparative examples 1-2 are prepared into aqueous solution to carry out after-finishing on the cotton fabric, and a blank control (the finishing agent is water) is carried out, then, the performance test is carried out, and the test result is shown in the table 1-2.
Hydrophilicity: the hydrophilicity was judged by dropping 1 drop of water from 1cm away from the fabric using a standard dropper (25 drops/mL) using the static drip method, with the time for complete absorption of the drop indicating the better hydrophilicity.
Hand feeling test property: and (3) a physical hand feeling evaluation method is adopted, the finished cloth sample is cooled and remoistened, and the original cloth hand feeling is rated as 1 point through comprehensive evaluation of multiple qualified hand feeling evaluation professionals from the aspects of smoothness, softness, filling power and the like, the hand feeling evaluation is preferably rated as 5 points, and the average value is taken.
Stability: and (5) standing for 24h in use environments with different pH values, ion interference and the like, and observing the state change of the solution.
TABLE 1 hydrophilicity and hand feel test results
| Test group | Hand feeling test | Hydrophilicity |
| Example 1 | 5 points of | 2s |
| Example 2 | 5 points of | 3s |
| Example 3 | 5 points of | 2s |
| Comparative example 1 | 3 points of | 6-10s |
| Comparative example 2 | 2 is divided into | 8-15s |
| Blank control | 1 minute (1) | - |
Table 2 stability test results
From the test results in tables 1-2, it can be seen that after the post-finishing of the fabric, the blank hand feeling is 1, while the fabric after the post-finishing by the high-permeability finishing agent for woven fabric of examples 1-3 of the present invention has excellent hand feeling and good hydrophilicity, while the working solution stability, especially alkali resistance and anion resistance of comparative examples 1-2 is obviously insufficient, the overall bulkiness of the hand feeling of the woven fabric after the finishing is poor, the hydrophilicity is obviously slow and is represented as that the hydrophilicity of different positions of the cloth surface after the finishing is not uniform, even is close to one time different, obviously, the finishing agent compounded by two different styles of compounds of compound a and compound B has the effect of greatly enhancing permeability during the post-finishing of the woven fabric, endowing the woven fabric with good hydrophilicity, hand feeling and fluffy feeling, and the finishing agent has self-emulsifying property and also provides more stable environmental adaptability, acid resistance, alkali resistance and good stability.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
