15-S-5, 15-S-9, 15-S-12 and 15-S-15 are secondary alcohol polyoxyethylene ether designations provided by the Dow chemical.
Further, the isomeric alcohol polyoxyethylene ether is preferably XP 50: XP90 ═ 1: 4, mixed isomeric alcohol polyoxyethylene ether.
Or further, the secondary alcohol polyoxyethylene ether is preferably 15-S-5: 15-S-9 ═ 3: 7. 15-S-5: 15-S-12 ═ 2: 3 or 15-S-5: 15-S-15 ═ 1: 1, mixed secondary alcohol polyoxyethylene ether.

The positive progress effects of the invention are as follows:
compared with the prior art, the zwitterionic amino silicone oil in the hydrophilic softening agent for silk fabrics not only retains part of unmodified amino silicone oil, but also increases anionic hydrophilic groups, quaternary ammonium cationic groups and hydroxyl groups. The silk fabric finished by the silicone oil emulsion has soft and elegant hand feeling of the silk fabric finished by the amino silicone oil, and meanwhile, the yellowing property of the fabric is reduced; hydroxyl in the silicone oil structure can be subjected to dehydration condensation with hydroxyl and carboxyl in the fabric, so that the reactivity and the washability of the fabric are improved; the existence of quaternary ammonium cation in the silicone oil structure can improve the fluffy feeling of the silk fabric after finishing. The ester quaternary ammonium salt in the softening agent has small irritation, and can effectively improve the hand feeling and the hydrophilic performance of treated fabrics by compounding with the zwitterionic amino silicone oil. The nonionic emulsifier can effectively improve the emulsification effect during the preparation of the softening agent and improve the stability of the softening agent. The strong base weak acid salt and the organic acid are used as pH regulators, so that the quality stability of the softening agent can be further improved. The components are mutually cooperated and matched, so that the hydrophilic softening agent for the silk fabrics has good quality stability, not only can endow the silk fabrics with soft, fluffy and elegant handfeel, but also does not influence the splitting and color of the silk fabrics, and simultaneously increases the hydrophilic performance of the silk fabrics.

Comparative examples 1 to 4 were prepared according to the procedures of examples 1 to 4.
Examples of effects
The products prepared in the above examples 1 to 4 and comparative examples 1 to 4 were used to prepare 10g/L of finishing liquid to finish the natural color heavy crepe silk fabric with the yarn size of No. 2.8. After the second immersion and the second rolling, the liquid carrying rate is controlled to be 60 percent, and after the drying at 120 ℃, the performance test is carried out after the moisture regaining:
(1) hand feeling
The hand feel was assessed by 5 experienced professionals using a touch method. Grade 1 indicates the worst hand and grade 5 indicates the best hand.
(2) Hydrophilicity
The faster the time of inhalation, the better the surface hydrophilicity as measured by AATCC 79-2000, measurement of Water absorption of textiles.
(3) Whiteness degree
And detecting the whiteness by adopting an SBDY-1 digital display whiteness meter. A larger number indicates a better whiteness.

The hydrophilic softening agent for silk fabrics prepared in examples 1 to 4 of the present invention has excellent quality stability, and as can be seen from tables 1 and 2, silk fabrics treated with the hydrophilic softening agent for silk fabrics prepared in examples 1 to 4 have good hand feeling and greatly improved hydrophilicity.
Compared with example 1, comparative example 1 is a silk softener commonly used in the market, and the composition difference is large, while comparative example 2 is not added with esterquat, comparative example 3 is not added with sodium acetate, and comparative example 4 is not added with zwitterionic amino silicone oil SF6150 and a nonionic emulsifier. Comparing tables 1 and 2, it can be found that the silk fabric treated by the hydrophilic softening agent for silk fabric prepared in example 1 has obvious advantages in hand feeling and hydrophilic performance compared with the silk fabric treated in comparison ratios 1-4, and meanwhile, the whiteness is not affected basically. The fabric treated by the comparative example 2 has good hand feeling and enough hydrophilicity, but the fabric can be dissolved and split, and the service performance is influenced. Therefore, each component plays a key role, and the components are mutually cooperated, so that the silk fabric softener disclosed by the invention is good in quality stability, not only can be used for endowing silk fabrics with soft, fluffy and elegant handfeel, but also the splitting and color of the silk fabrics are not influenced, and meanwhile, the hydrophilic performance of the silk fabrics is increased.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited thereto, and that various changes and modifications may be made without departing from the spirit of the invention, and the scope of the appended claims is to be accorded the full scope of the invention.
