Embodiment 1-1

[0016] Example 1-1 Preparation of α, ω-amino polysiloxane intermediate

[0017] In a 2000ml three-necked flask equipped with a constant speed electric stirrer and a thermometer, add 1230g of octamethylcyclotetrasiloxane (D4) and 50 grams of 1,1,3,3-tetramethyldiaminopropyl disilazane Oxygen, stir and heat up to about 90-95°C, then add 1.28g (CH 3 ) 4 NOH content of 10% (CH 3 ) 4 NOH alkali glue, heat preservation reaction for 6 hours, after the heat preservation is over, the temperature is raised to 135 ° C, and the heat preservation is 1 hour, and the catalyst (CH 3 ) 4 The NOH is fully decomposed, vacuumized slowly, and a large amount of low boiling material flows out. Under the condition of temperature of 150°C and relative vacuum degree of -99.9KPa, pull out the low boiling material for 1 hour until no material flows out. The synthesized product is a colorless transparent viscous liquid, the ammonia value is 0.345mmol / g, the viscosity is 50-55cs, and the volatile con...

Abstract

The invention relates to the textile finishing agent field, in particular to a super-soft finishing agent of silicone oil. The super soft finishing agent of the silicone oil comprises a silicone oil compound with the following cation structural formula as followed. The silicone oil compound occupies a weight percentage of 2%-60% in the finishing agent, the n1 is 5-10, the R is a polyether group, and a polymerization degree is 3-50. The super soft finishing agent of the silicone oil is suitable for feel finishing of one or more fiber constituted fabric such as cotton, Dacron, chinlon and acrylic fibers, and provided with better soft, smooth and fluffy effects than amino-modified silicone oil and excellent stability in resistance to acid and alkali, electrolyte, high temperature, shearing and the like; and problems of easy demulsification, floating oil, roll banding, difficult rework and the like in the existing amino-modified silicone oil are completely solved.

Description

technical field [0001] The invention relates to the field of textile finishing agents, in particular to a supersoft silicone oil finishing agent. Background technique [0002] At present, more than 80% of the hand finishing agents for textiles on the market need to use amino silicone oil. Amino silicone oil is a modified silicone oil developed in the 1980s and mainly used for soft, fluffy and smooth handle finishing. Its molecular main chain is composed of Si-O bonds with excellent flexibility. The aminosilane coupling agent introduces amino groups of different structures, which have strong polarity, reactivity, adsorption and other chemical characteristics, thus endowing amino silicone oil with innate advantages in the effect of fabric hand finishing. However, amino silicone oil cannot be used directly, and must be emulsified with an emulsifier before use. After years of technological development, the selection of amino silicone oil emulsifiers and the optimization of the...
