Problems solved by technology

[0009] However, although DETA itself is not AEEA and is an environmentally friendly substance, it cannot completely replace AEEA due to the yellowing of the products produced by it.

Embodiment 1

[0032] Example 1. Preparation of hydroxypropylethylenediamine

[0033] In this example, hydroxypropylethylenediamine is prepared as one of the softener raw materials. Carry out with reference to the technical scheme and the reaction kettle recorded in the patent ZL200910032856.6 "Continuous production of hydroxyethylethylenediamine production process and its reaction kettle". Specifically, in this embodiment, the reaction tower of the patent is used, and propylene oxide is used to replace the ethylene oxide in the patent, and other process conditions are basically unchanged, and the purity is above 99% after synthesis and rectification. of hydroxypropylethylenediamine (AEPA).

Embodiment 2

[0034] Example 2. Preparation of N-hydroxypropyl diethylene triamine

[0035] In this example, N-hydroxypropyl diethylene triamine (hydroxypropyl diethylene triamine) is prepared as one of the softener raw materials. Utilize the reaction kettle, under nitrogen protection, under the condition of 80~150 ℃, 0~0.5MPa, add propylene oxide to the continuous feeding method of diethylenetriamine; wherein the molar ratio of diethylenetriamine and propylene oxide is 1 : 1, the obtained product is N-hydroxypropyl diethylene triamine (referred to as hydroxypropyl diethylene triamine).

Embodiment 3

[0036] Example 3. Preparation of N-hydroxyethyldiethylenetriamine and N,N'-dihydroxyethyldiethylenetriamine

[0037] In this example, N-hydroxyethyl diethylene triamine and N,N'-dihydroxyethyl diethylene triamine are prepared as one of the softener raw materials. Using the reaction kettle, under the protection of nitrogen, under the conditions of 80~150℃ and 0~0.5MPa, ethylene oxide is added to diethylenetriamine by continuous feeding method; When the molar ratio is 1:1, the obtained product is N-hydroxyethyl diethylenetriamine; when the molar ratio of diethylenetriamine to ethylene oxide is 1:2, the obtained product is N,N'- Dihydroxyethyldiethylenetriamine.

Abstract

The invention provides an environment-friendly softening agent which is used for hand feeling finishing of fabric. The softening agent is a product obtained through the following steps: dehydrating raw materials: organic amine and fatty acid in nitrogen atmosphere with phosphorous as a catalyst at the temperature of 180-200 DEG C and then dehydrating under the vacuum condition at the temperature of 200-240 DEG C; and finally, performing quaterisation and acidification. According to the invention, the softening agent, which has good hand feeling and low yellowing performances consistent with those of a softening agent commonly used at present, can be obtained by replacing a raw material: AEEA (aminoethylethanolamine) of the softening agent commonly used at present with a series of organic amine such as hydroxy-propyl-ethylenediamine and the like under the condition that the molar ratio is not changed, so that the environment and health problems caused by AEEA can be solved.

Description

technical field [0001] The invention relates to the field of textile functional finishing agents, in particular to an environment-friendly softener and a preparation method thereof. Background technique [0002] Softeners used in textiles can generally be divided into silicones and non-organic silicones. The latter are mainly cationic products, generally with saturated hexadecanoic acid, octadecanoic acid, and hydroxyethylethylenediamine (AEEA or ethylenediamine). It is called aminoethylethanolamine), diethylenetriamine, etc., to obtain imidazoline or amide, which is quaternized and acidified to obtain common products. Amines mainly focus on the use of the above two raw materials, which are relatively simple. Although there are many types of other raw materials, the quantity is not large. [0003] The unsaturated acid is replaced by the saturated acid, and the corresponding hydrophilic softener can be obtained according to the above-mentioned process, and such products are ...
