Abstract

The invention relates to a finishing process for self-cleaning anti-bacterial and odor-resistant multifunctional dacron fabric. The finishing process comprises the steps of dyeing, anti-bacterial and odor-resistant finishing in one bath, soaping, processing and self-cleaning finishing. The dacron fabric finished through the finishing process has the self-cleaning anti-bacterial compound function and is good in moisture-penetrability.

Description

A kind of self-cleaning antibacterial deodorization multifunctional terylene fabric finishing technique

Technical field

The application relates to a kind of polyester fabric finishing technique, relates in particular to a kind of self-cleaning antibacterial deodorization multifunctional terylene fabric finishing technique.

Background technology

Polyester fabric is chemical fiber garment fabric commonly used in daily life, its wrinkle resistance and conformality are fine, be applicable to makeing the overcoat clothes, but the polyester fabric anti-microbial property that traditional finishing technique arranges out is poor, without the automatically cleaning effect, need badly a kind of polyester fabric finishing technique that makes polyester fabric have the good and automatically cleaning effect of anti-microbial property be provided based on this.

Summary of the invention

For these reasons, the present invention proposes a kind of self-cleaning antibacterial deodorization multifunctional terylene fabric finishing technique, it comprises the following steps:

1) dyeing, anti-bacterial purifying finish are with bathing;

2) post processing of soaping;

In this step;

Acidic reduction cleaner: 2.0-4.0g/L

Bath raio: 1:10-15, same temperature * time of bathing: 80 ℃ * 20min;

Heat is washed, washes, dewaters, is dried, and bake out temperature is 100 ℃, and the time is 3min;

3) self-cleaning finishing;

In this step, adopt the nano TiO 2 composite photo catalyst, this nano TiO 2 composite photo catalyst is the metal doping nano TiO2 transparent photo-catalytic emulsion that Changchun Hua Jing Environmental Protection Technology Co., Ltd produces, crosslinking agent polyurethane 10-15g/L (mass concentration), the nano TiO 2 composite photo catalyst is poured in the soak of 40 ℃ of water temperatures that prepare with dacron weight 1:10-15, stir, by clean and dewater after dacron evenly put into described soak and soak; After soaking 30min, dewatered, to the carpet preliminary drying of the rear corresponding fabric that dewaters, the preliminary drying temperature is 110 ℃, and the time is 165 ℃ of 3min, baking temperatures, and the time is 1min, makes the nano TiO 2 material be adsorbed onto securely dacron inside.

Dacron after this technique arranges has antibiotic, self-cleaning composite function, and the poisture-penetrability maintenance better, and gas permeability slightly descends.The antibacterial finishing agent used is a kind of non-dissolution type durable antibiotic finishing agent, is an organic inorganic composite antimicrobial finishing agent, wherein contains our antibiotic common element of knowing such as silver, titanium, silicon, and itself is nontoxic, and higher security performance is arranged, and it is convenient to arrange.Adopt dyeing anti-bacterial purifying finish one-bath finishing technique, not only easy to operate, and TPM9007 dyes polyster fibre inside on when high temperature, TPM9007 is fixed in fibrous inside and is subject to the protection of fiber, therefore have washability and broad-spectrum antimicrobial effect reliably.In addition through the dacron of self-cleaning finishing for organic oil stain, there is good automatically cleaning effect under the condition of illumination, and there is fastness to washing preferably, kept the original style of dacron simultaneously.

For after improving and soaping, function reduction is a lot.By introducing polyurethane, polyurethane is the base polymer that main chain contains carbamate groups (NHCOO-) constitutional repeating unit, by isocyanates (monomer) and hydroxy compounds, is polymerized.Contain more reactive group in polyurethane, large intermolecular generation is crosslinked, again owing to containing more carbamate groups (NHCOO-), urea groups (NHCONH-) isopolarity group, under strong electrostatic interaction, just can produce more hydrogen bond, the formation hydrogen bond is crosslinked, has good film forming, toughness, ABRASION RESISTANCE and cohesiveness, can improve the binding strength of nano TiO 2 composite photo catalyst to fabric.

The specific embodiment
