Problems solved by technology

[0005] However, the existing softeners can only improve the softness of the fabric to a certain extent, and cannot make the softness of the fabric reach the level of real silk. So far, the world can fully realize the imitation silk and the crepe chine imitation silk of ultra-fine silk imitation silk products. Products, world-class silk products, including wool products, there are only two countries at present, but the corresponding technology adopted has not been made public
In addition, the existing softening and finishing methods all use dipping and finishing methods. In order to impregnate the fibers, a large amount of water (the amount of water used is about 30 times that of the softening agent) is required, thereby correspondingly producing a large amount of waste liquid (3 One ton of soaking liquid will produce more than 2 tons of waste liquid), the treatment of these waste liquids is also a problem, and the cost will be increased if the treatment is carried out, and the environment will be seriously polluted if it is not treated
Moreover, the existing process cycle is long, usually up to 24 hours, the long-term operation is inconvenient for temperature control, and greatly increases the cost

Embodiment 1

[0032] The invention provides a fiber softening composition, which consists of 19.27kg of waste silk extract, 26.04kg of lemon vinegar, 2.8kg of PK antistatic agent, 1.4kg of emulsified silicone oil OP-4, 160kg of distilled water (re-distilled) and dodecyl Dimethyl benzyl ammonium chloride is mixed with 0.5kg, and the waste silk extract is extracted from waste silk through ether reflux, which contains 38.4% silk protease; lemon vinegar is vinegar made from lemons, which contains acetic acid 40%; the content of active ingredients in PK antistatic agent is 35.7%, and the content of active ingredients in silicone emulsifier is 35.7%.

Embodiment 2

[0034] The invention provides a fiber softening composition, which is formed by mixing 1.2kg of SN series softener, 28kg of Pingpingjia, 7.7kg of diisopropanolamine stearate, 1kg of PK antistatic agent, 2kg of butyl cellosolve and 160kg of distilled water .

Embodiment 3

[0036] A soft treatment method for silk-like polyester fiber (50D / 96F high-fine denier yarn), the device used includes a pressure vessel capable of withstanding a steam pressure of 0.3MPa (3kg), a steam supply device and two pressure gauges of more than 5kg , The pressure vessel has an air inlet and an air outlet, and is equipped with a safety valve. The steam supply device supplies steam through the air inlet, and the supply and disconnection of the steam are controlled by valves.

[0037] The processing method in this example includes the following steps:

[0038] (1) Pack the imitation silk polyester fiber into the required measurement, wrap it with cloth, add it to the pressure vessel, and dilute the fiber softening composition with the composition of Example 1 at a concentration of 10% of the composition content Prepare the fiber softening treatment liquid, and spray the fiber softening treatment liquid on the surface of the fiber, the fiber will be submerged in the trea...

Abstract

The invention relates to a synthetic fiber softening treating method and a fiber softening treated composition. The treating method comprises the following steps: (1) spraying a fiber softening treating liquid on synthetic fiber to be treated in a pressure container; (2) introducing vapor into the pressure container, exhausting simultaneously, using the introduced vapor to discharge cold air in the pressure container, after the cold air is discharged, closing an exhaust opening, simultaneously introducing vapor until the pressure inside the pressure container is 0.1 to 0.2 MPa at the temperature of 110 to 115 DEG C, stopping the introduction of the vapor, standing for 20 to 30 minutes, opening the pressure container, taking out the synthetic fiber, and drying. The composition contains fibroin enzyme, acetic acid, an antistatic agent, a silicone emulgator, dodecyl dimethyl benzyl ammonium chloride and water. The softening treating method disclosed by the invention is short in treatment time, is free of waste liquid emission and treatment problem, green and environmentally-friendly, economical and efficient, convenient in operation and safe; and moreover, the method disclosed by the invention has an excellent softening effect on fiber.
