The REACH regulation, batch 25, item 8 SVHC, list requires that no 1, 4-dioxane is detectable in the chemicals, and accordingly, environmental regulations such as Bluesign, GOTS, etc. also propose to disable 1, 4-dioxane, ethylene oxide. Therefore, the finishing agent capable of endowing the fabric with durable hydrophilicity and soft and smooth hand feeling is prepared, does not contain ethylene oxide impurities, and has less than 10ppm of 1, 4-dioxane, so that the finishing agent is urgently required by the market.

Example 4
The difference from example 1 is that in step A, 20g of fatty alcohol-polyoxyethylene ether is used.
Example 5

3) equimolar amounts of white solid and NaOH were dissolved in ethanol, stirred for 3h, and the solvent was removed, yielding the dispersant sodium octanoyl tryptophan.
Comparative example 1
The difference from example 7 is that tryptophan is replaced by phenylalanine.
Performance testing
The environment-friendly finishing agent for the sports fabric prepared in each example is subjected to 1, 4-dioxane and ethylene oxide content test and fabric finishing performance test.
The finishing method comprises the following steps: preparing a finishing agent into 10g/L working solution by using tap water, soaking and rolling the polyester knitted fabric at room temperature, shaping and drying at 160 ℃, dampening at room temperature for 2 hours, dividing the fabric into three parts, testing the hydrophilicity of one part, evaluating the hand feeling of the other part, and testing the hydrophilicity of the other part after washing for 20 times according to GB-8629.
The hand feeling evaluation method comprises the following steps: the hand feeling effect of the fabric is evaluated by touching the finished fabric surface with hands, the hand feelings in the aspects of smoothness, softness and the like can be respectively evaluated by more than five persons, and then comprehensive sequencing is carried out. The best hand fabric was rated on a 5 scale and the worst hand fabric was rated on a 1 to 5 scale.
Hydrophilic test method: selecting four different points on the surface of the finished fabric, dripping a drop of water on the surface of the fabric from the height of 2cm, testing the time required for the mirror reflection of the drop of water to disappear, namely the wetting time, taking an average value, and evaluating the good and bad hydrophilicity (water absorption) of the fabric according to the time length.
From the comparison of the data of examples 1 and 2, the ethylene terephthalate is added in an excessive amount, the reaction is not completed, and the unreacted monomer may produce side reaction to produce 1, 4-dioxane during the reaction. Comparing the data of examples 1 and 4, it can be seen that when the amount of the emulsifier is too small, the emulsification is incomplete, the particle size of the emulsified product is large, the reaction is not facilitated, and 1, 4-dioxane as an impurity may be generated.
Compared with the data of the examples 1 and 3, the hand feeling and the hydrophilicity are relatively improved when the addition amount of the amino-terminated silicone oil is increased; the data of examples 3 and 5 show that when the addition amount of the ethylene terephthalate is increased, the hydrophilic speed of the treated fabric is increased, and the hydrophilic speed of the fabric is also obviously increased after 20 times of washing, which indicates that the increase of the addition amount of the ethylene terephthalate is beneficial to the improvement of hydrophilicity and washability.
Example 7 did not differ much from example 5 indicating that the addition of home-made dispersant did not affect the fabric properties. Example 7 the advantage of adding a homemade dispersant is mainly represented by the shortened homogenization time. In examples 1 to 6 including example 5, the step B needs to be homogenized for 1 to 1.5 hours to ensure that the particle size is less than 500nm, and in example 7, the step B needs to be homogenized for 24 minutes to ensure that the particle size is less than 500nm, so that the homogenization time is greatly shortened, and the method has important significance for practical production. Comparative example 1 a dispersant was prepared using phenylalanine instead of tryptophan with a homogenization time of 40min, and the efficiency was clearly inferior to that of example 7, indicating that the tryptophan structure plays an important role in the homogenization efficiency.
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.
