Especially in large-scale fluffing, the fluffing must reach a certain length of fluff, and the fluff on the cloth surface is required to be uniform, smooth, smooth, and full in hand. Use common fluffing agents (such as: softener-101, softener HC, soft Agent BS-31, flake softener-71, fabric fluffy fluffing agent WF-10, fluffy amino silicone oil TS-170K) cannot meet the above requirements

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing and embodiment, but should be understood that these embodiments do not limit the scope of the present invention, without departing from the spirit and scope of the present invention, those skilled in the art can make changes and modifications to the present invention Improved to make it suitable for different use cases, conditions and implementations.
[0015] The production technique of this raising agent of the present invention, step is as follows:
[0016] (1), add 600-800 kilograms of octamethylcyclotetrasiloxane (organosilicon basic product D 4 ), 0.2 to 1.8 kilograms of catalyst, the air in the kettle is replaced with nitrogen, and the reaction kettle is closed after 15 to 20 minutes at a flow rate of 25 to 50 liters / minute;
[0017] (2) Use jacket steam to heat up to 100-125°C for ring-opening polymerization reaction for 2-10 hours to obtain high-molecular-weight sili...

The invention relates to a production process of raising agent, which adopts the following steps: 1. Glass-lined reactor is filled with octamethycyclotetrasiloxane and catalyst, after the air in the reactor is replaced by nitrogen, the reactor is closed; 2. Use jacketed steam to raise temperature to 100-125 DEG C and perform ring-opening polymerization reaction for 2-10 hours, and then at 120-130DEG C vacuum level is controlled at 600-700mmHg for 0.5-2 hours; 3. cool to 60-70 DEG C, the material is turned to an emulsifier, emulsifying agent is added into the emulsifier for even mixing, and the deionized water is added so as to prepare into be an emulsified liquid with specified content, and then the emulsified liquid is turned into a mixing pan and finally a matched auxiliary agent is added into the mixing pan, so that the raising agent is formed. The invention has the advantages that: emulsifying device is adopted to prepare emulsified liquid, the emulsified liquid is prepared with the matched auxiliary agent compositely so as to reach the requirements of coordinate efficiency of each component and also the fluffing of pure polyester leather substrate; the production process hasthe advantages of simple flow process, low production cost, no three- wastes, and industrialized production.
Description
technical field [0001] The invention relates to a polymer organosilicon compound and a supporting auxiliary agent, mainly a production process of a raising agent. Background technique [0002] Pure polyester woven fabrics, warp-knitted and weft-knitted fabrics are the main base fabrics for shoe upper leather. Pure polyester fabrics are raised and finished after high-temperature and high-pressure disperse dyeing. Pure polyester fiber is a polyester polymer compound, the surface of the fiber is smooth, the mechanical strength is high, and it is generally not easy to fluff and fluff. Especially in large-scale fluffing, the fluffing must reach a certain length of fluff, and the fluff on the cloth surface is required to be uniform, smooth, smooth, and full in hand. Use common fluffing agents (such as: softener-101, softener HC, soft Agent BS-31, flake softener-71, fabric fluffing agent WF-10, fluffy amino silicone oil TS-170K) cannot meet the above requirements.
