Abstract

The invention relates to the technical field of organosilicon softeners in textile softeners, in particular relates to an organosilicon compound for textile softeners and a preparation method thereof. The organosilicon compound is finally obtained by adding octamethylcyclotetrasiloxane and hydrogen-containing silicone oil to react, carrying out a further reaction after vacuumizing and adding alkali for neutralization and then adding glycidyl ether, NH2(CH2CH2O)aR1NH2, NH2R2(CH2(CH3)CHO)c-(CH2CHO)dR3NH2 and the like, wherein R1, R4R1, R2, R3 and R4 are 2-8 alkylamines of a carbon chain; a is equal to 3-10; b is equal to 2000-10000; c and d are equal to 3-15; and e is equal to 2000-10000. The organosilicon has excellent film-forming property, stability and handfeel on the textiles by adopting a new structure and has better stability and handfeel compared with that of the conventional amino / polyester silicone oil.

Description

[technical field] [0001] The invention relates to the technical field of silicone softeners in textile softeners, in particular to a novel linear amino and polyether modified organosilicon compound used in textile softeners [Background technique] [0002] Softening is an important auxiliary agent for the treatment of natural fibers and synthetic fiber fabrics. The softeners used in the early days include amino-modified polydimethylsiloxane, etc., which have solved the problem of industrialization and scale. The cost has its own special advantages, but because it needs to solve the problem of oil in water, its poor stability (commonly known as sticking rollers and oil floating problems in the market) limits its use. [0003] In order to solve the problem of insufficient stability of amino silicon in the market, there is also a softener based on polyether silicone oil in the market. For example, the domestic application CN101418518A discloses a durable hydrophilic polyether mo...
