涂料印花粘合剂概述

一、前言涂料印花粘合剂是涂料印花浆的主要成份,各种染料或颜料靠粘合剂成膜使其粘盖在织物上,从而达到着色印花之目的。涂料印花所用的颜料主要是分散染料,也可用萤光颜料、金粉、银粉等颜料。所用粘合剂从无机到有机物质,从低分子到高分子物质,其发展历史是比较悠久的。特别是七十年代出现的可以交联的粘合剂,如丙烯酸酯共聚乳液(单体中加入了自交联单体)粘合剂问世以后,涂料印花粘合剂的发展更为迅速。它在印染行业中占有极其重要的地位。本文结合科研工作,将国内外涂料印花粘合剂的发展、合成和应用情况,作一简要介绍。

Synthesis of cationic binder through surfactant-free emulsion polymerization for textile pigment applications

The cationic P(DMDAAC-BA-MMA-HEA) copolymer latex was prepared with diallyldimethylammonium chloride, butyl acrylate, methylmethacrylate and hydroxyethyl acrylate as monomers via surfactant-free emulsion polymerization. The structures and morphologies of the latex were confirmed by Fourier transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM). The utilization performance of the cationic latex as a binder for pigment dyeing of cotton fabrics was investigated. FT-IR showed that the polymer was prepared successfully. TEM micrograph revealed that the hybrid latex particles were uniform spheres with the diameter ranged from 500 to 600 nm. Cotton fabric dyed with the cationic binder demonstrated 3–4 grade dry and wet rubbing fastness and 4 grade soaping fastness, which were comparable with commercial binders. Moreover, the binder can be used safely in pigment dyeing to give the dyed fabric improved hand feel and excellent elongation at break. It could be said that an efficient way to produce a binder with good performance was developed by the use of cationic emulsifier-free emulsion polymerization.     

A novel strategy for realising environmentally friendly pigment foam dyeing using polyoxyethylene ether surfactant C14EO5 as a foam controller

Development of an environmentally friendly pigment dyeing process with excellent colour depth and levelness is an effective strategy for solving pollution problems in traditional dyeing. A functional polyoxyethylene ether nonionic surfactant, tetradecyl alcohol polyoxyethylene ether with an EO chain length of 5 (C₁₄EO₅), was used as a foam controller, namely a foaming agent and foam stabiliser, in the pigment foam dyeing process. The foamability and the foam stability of C₁₄EO₅ were tunable by adjusting its concentration. The foaming ratio and the foam half-life of C₁₄EO₅ were 5.22 and 32.21 min, respectively, at a concentration of 8 wt%. The addition of pigment dispersion (ranging from 1 to 6 wt%) slightly affected the foaming ratio and the foam half-life owing to the interplay of increased viscosity and pigment particle destabilisation. After the influences of binder on foam properties of C₁₄EO₅ were investigated, the concentration of binder and the stirring time for foaming were determined as 15 wt% and 7 min respectively. Owing to the stable foaming ratio and foam half-life of the pigment foam dyeing dispersion, the colour depth of dyed cotton fabric was tailored solely by changing the dosage of pigment dispersion. Furthermore, the dyed cotton fabric showed not only a high K/S value but also perfect colour levelness and fastness. These results demonstrate that the pigment foam dyeing process with a foam controller, C₁₄EO₅, reduces chemical and water consumptions, as well as improving the colour depth and levelness. This represents a significant step forward as regards environmentally friendly pigment dyeing.     

Novel pigment binders based on S-thiosulphato (Bunte salt) terminated polyethers

An initial study has been undertaken to determine the viability of using S-thiosulphato (Bunte salt) terminated polyethers as pigment binders. Three such polymers (two synthesised and a commercial product) of different molecular mass and functionality were investigated. Two substrates were employed: wool fabric as prepared for dyeing and cotton fabric modified with a cationic polyamine. Pigments dispersed in anionic surfactants show high substantivity for the latter substrate and as a result these dispersions can be successfully applied to appropriately treated fibre by exhaust methods. In all cases high standards of wash fastness were achieved without affecting the fibre handle. On cotton each binder showed relatively low fastness to rubbing. On wool a good all-round fastness was achieved with one of the Bunte salt polyethers. The polymers also displayed excellent properties for use as dispersing, wetting and shrink-resist agents.

Modelling the properties of pigment‐dyed polyester/cotton sheeting fabrics by response surface methodology

The aim of this study was to model the effect of pigment, binder and fixer concentrations on the rubbing fastness, crease recovery, tear strength and stiffness of pigment‐dyed polyester/cotton sheeting fabrics. The design and analysis of experiments were carried out using Minitab^® statistical software according to the central composite design of response surface methodology. It was found that an increase in the binder concentration significantly improves the dry rubbing fastness, crease recovery and stiffness of the fabric, with a corresponding decrease in fabric tear strength, without significantly affecting the wet rubbing fastness. An increase in the fixer concentration significantly improves both the dry and wet rubbing fastness and crease recovery, with a decrease in fabric tear strength and stiffness. The effect of binder and fixer concentrations on crease recovery was not linear and there was significant negative interaction between these factors for dry rubbing fastness. The effect of pigment concentration was not found to be statistically significant for the types and range of concentrations of pigment, binder and fixer used in this study.

Modelling the properties of pigment‐printed polypropylene nonwoven fabric using the Box–Behnken technique

The aim of this study was to develop statistical models for the effect of binder concentration and curing temperature and time on the air permeability, tear strength, tensile strength, and crocking fastness of pigment‐printed nonwoven polypropylene fabric. The design and analysis of the experimental work were carried out using Minitab ^® statistical software according to the Box–Behnken design of response surface methodology. Models were successfully developed. It was found that binder concentration improves the wet crocking and tensile strength while having a negative impact on all other responses. Increase in curing temperature and time affects the fabric tear strength negatively but has a positive effect on wet crocking fastness and fabric tensile strength. It could be concluded that pigment prints of good dry crocking fastness may be obtained on polypropylene nonwovens without deterioration in the mechanical strength and air permeability to a commercially unacceptable level. However, further work is required to improve the wet crocking fastness properties.     

Dyeing and fastness properties of benzodifuranones, naphthodifuranones and naphthofuranonepyrrolidones

Dyeings were carried out on polyester with benzodifuranones, naphthodifuranones and naphthofuranonepyrrolidones (which had been synthesised previously) to study dyeing properties. Symmetrically and asymmetrically substituted naphthodifuranones showed poor dyeing properties in terms of dyeing and fastness. Asymmetrically substituted red benzodifuranones showed excellent dyeing properties and fastness. Asymmetrically substituted blue benzodifuranones showed good dyeing properties; however, the colour hue was dull and the light fastness was inferior. The naphthofuranonepyrrolidones showed similar dyeing and fastness to those of symmetrically substituted naphthodifuranones, but the colour hue was duller.
