Embodiment Construction

[0033] A cellulose fiber fabric modification finishing process disclosed by the present invention, the steps are as follows:

[0034] The first step is to use γ-aminopropyl triethoxysilane as raw material, through acidification catalysis, hydrolysis and condensation, to synthesize polyγ-aminopropyl silsesquioxane (POSS) with a caged structure containing octaamino groups. -NH 2 ).

[0035] Hydrolysis and condensation reactions:

[0036]

[0037] When Si-OH and Si-OH collide, a nucleophilic attack occurs, the water molecules are removed to complete the condensation process, and Si-O-Si bonds are formed. By controlling the process conditions of hydrolysis and condensation, POSS with a regular structure containing octaamino groups can be synthesized , a cage-structured polyγ-aminopropyl silsesquioxane (POSS-NH 2 )as follows.

[0038]

[0039] In the second step, polyγ-aminopropyl silsesquioxane (POSS-NH 2 ), the reactive poly-N methoxy clathrate silsesquioxane (POSS-N(C...

Abstract

The invention discloses a modification finishing process of a cellulose fibre fabric. The technological process is as follows: by using gamma-aminopropyl triethoxysilane as a raw material, synthesising out poly-gamma-aminopropyl polyhedral oligomeric silsesquioxane POSS-NH2 with a regular octa-amino-group-containing cage structure through acidification catalysis, hydrolysis and condensation, preparing reactive multi-N-methoxyl cage-like silsesquioxane POSS-N(CH2(OH))2 through formylation reaction, and then carrying out padding cross-linking modification finishing, drying and roasting on the mixture solution of the cellulose fibre fabric and the POSS-N(CH2(OH))2, thus the elastic recovery performance of the finished cellulose fibre fabric is effectively improved, and with the increasing of the concentration of the POSS-N(CH2(OH))2, the (warp-directional and weft-directional) wrinkle recovery angles of the finished cellulose fibre fabric are obviously increased, thus improving the shrink-proof and wrinkle-proof performances of the fabric.

Description

technical field [0001] The invention relates to the technical field of modification and finishing of cellulose fiber fabrics in the textile manufacturing industry, in particular to the printing and dyeing fabrics of cotton, tencel, modal, viscose fibers and their blended fabrics and (POSS-N (CH) 2 (OH)) 2 ) mixture solution padding, cross-linking modification finishing process. Background technique [0002] With the development of science and technology, human beings have put forward more and higher requirements for the performance of materials. Single organic materials or inorganic materials can no longer meet the needs of industrial and social development. The development of new materials that can take into account the properties of hydrocarbon organic materials and inorganic ceramic materials has become a hot spot in current materials science research. Silicone resin is a cross-linked semi-inorganic polymer with Si—O—Si as the main chain and organic groups connected to ...
