The reason of half of clothing and shoes exported to Europe and the United States were recalled

Recently, Shanghai Caison Technical Dept. is working for collection of industrial information, and one article published on the "Shanghai Dyes" magazine, it was written by Mr. Zhang who is one of senior engineer of dyes. Its title is "Hazards factor analysis of chemical composition in the recalled Chinese clothing and shoes products in recent years" Caison Technical dept. has focused on it and paid more attention to these industrial news about pigment paste or dyes.

The European Union RAPEXalarm system is introduced by Mr. Zhang in this paper, it is EU's non-food-based dangerous consumer goods rapid warning system, which was established based on the European Union 2001/95 / EC "General Product Safety Directive”. And the goal is finding out non-food based dangerous consumer goods information and promptly transferring to all other EU Member States regulatory bodies!
RAPEX warning notification is running for 12 years, China is the country that received the most notices and recalls. During these recalled products, clothing and footwear products is the highest proportion, and involved in the notification mainly including chemical hazards and related personal injury.

Nearly three year, Chinese exporting clothing and shoes products noticed by RAPEXD have to be noted that 16 violation incidents of REACH regulations in 2014, and suddenly up to 38 incidents in 2015. The proportion of clothing and shoes products in this had increased from 5.06% in 2014 to 21.59% in 2015.
Shanghai Caison Technical Manager has noted that the using of prohibited azo dyes in clothing and shoes products is main reason of recalled products from EU, and its proportion is reach 47%, and except other chemicals components exceeded in REACH which has nothing to do with textile printing and dyeing. So we think this is entirely caused by choosing and using no safe dyes in the textile printing and dyeing.  Some of prohibited AZO dyes would produce carcinogenic aromatic amines under the condiiton of reduction, such as 4-amino azobenzene, 3,3-dimethoxy benzidine, benzidine, and so on!

Why does these Chinese suppliers use prohibited AZO dyes in the production of apparel and footwear?
Mr. Zhang has talked about two reasons:
One is that several dyes companies still illegal produce and sale those strictly prohibited carcinogenic aromatic amine intermediates and banned azo dyes, because they want to obtain improper interests and malicious competition.
Two is the lacking of studying and learning of banned AZO dyes in some textile printing and dyeing factoies. Or unintentional using prohibited AZO dyes, and those dyes will release carcinogenic aromatic amines in the specific conditions.

Why does Caion Technial Manager would so concern about these industry articles?
Because Caison has three main series water based pigment paste developed for textile printing and dyeing. They are Casion CTH series eco-friendly water based pigment paste for textile pigment printing; Caison D series eco-friendly water based pigment paste for textile pigment dyeing; Caison CD series textile cationic dyeing pigment paste.  And these pigment paste all meet REACH regulatory standards, and also conform to 24 kinds of prohibited aromatic amine limited requirement in EU textile safety standards OEKO-TEX100 Standard.

One case of after-sales service |fade complaint of garment dyed by Caison pigment paste|why?

One morning in early Septemper, Mr. Cui who is one of saler in Shanghai Caison Color received a call from one iof his clients in Zhejiang Province, the client told him that his customer had a complaint about T-shirt product dyed by Caison water based pigment paste D-204 Golden yellow and D-304 Navy blue. He said the dyed T-shirt had been fade after one month displayed in the showcase of store, just as picture shown, the blue color was uneven.

Mr.Cui reported this case  and transferred the T-shirt picture to the Caison Technical dept., Manager Li analyzed it and checked the pigment paste fastness index, he thought the color fade reason was lower color sunlight fastness, and mainly fade color was blue,but yellow was not. So he confirmed that blue color was lower sunlight fastness.  But Caison D-304 Navy blue pigment paste had higher sunlight fastness, it could not happen color fade.  The sunlight fastness of Caison these two types of pigment paste was following:

D-204 Golden yellow: 4-5 Grade;

D-304 Navy blue: 5-6 Grade;

Here Manager Li found that this case was not normal caused from this client, so he asked the final customer's call number from this client, and wanted to check with him two questions:

 1. Did the customer use other colors to dye the T-shirt with Caison pigment paste together?

 2. Did the gray fabric dyed by Caison D series pgiment paste directly?

 3. If it was ture, Caison would do the same testing of color fade in lab, then to check if any problems?

At last, the final customer told Manager Li that they has used direct sky blue  dyes bottoming, then dyed shirts with Caison D series pigment paste, because they wanted to make a special style.

Manager Li had called this agent in Zhejiang Province, and pointed out the actual reason was lower sunlight fastness of direct sky blue dyes.   Because its main material was direct blue 15, and its sunlight fasntees is only 1-2 grade which was far lower than Caison D-204 and D-304.

The final customer acknowledged this reason and showed more trust in our pigment paste products。

The experiment of dyeing temperature and dyeing bath ratio of CD cationic pigment paste

The experimental purpose: CD series textile cationic dyeing water based pigment paste developed by ourselves can directly combine with fabric cellulose matrix. The particle size of pigment dispersed in pigment paste is about 2 microns, color is depth and vividness, so can be made "one-step dyeing" with it. This dyeing process is simple, can save energy and labor, reducing colored waste water discharge. And this experiment purpose is finding out the suitable bath ratio of CD water based pigment paste, in order to make the data preparation for users.

The experimenters: CD product project team members of Shanghai Caison R&D Dept.

The experimental material: CD series textile cationic dyeing pigment paste, matched CAISON CDB-1 cationic binder, cotton knitted fabric 105g/m2.

The experimental equipment: commonly small equipment in lab;

The testing method: dip dyeing way, preparing different ratios of CD cationic pigment paste liquid, then make dyeing rate calculation after dyeing finished when using different dyeing temperstures， and record the data.

The standard dyeing liquid ratio: separately formulate 1mg/L, 2.5mg/L, 5mg/L, 7.5mg/L, 10mg/L, 15mg/L, 20mg/L.

Testing a certain concentration of dip dyeing, then take out some residue dyeing liquid and dilute to a lower concentration according to certain proportion,  making the comparison with standard concentration of dyeing liquid and determine the concentration diluted. At last, calculating the residual liquid concentration Ci before dilution. The dyeing uptake is calculated as follows:

The dyeing uptake = (1 - Ci / Co) × 100%

 Co---- dyeing liquid concentration before dyeing;

 Ci---- dyeing liquid concentration after dyeing;

Experimental results

1. Temperature factor：

The dye uptake of dip dyeing with CD series pigment paste is higher than normal pigment paste, 6-8% dyeing concentration is almost dyed fully. So we just to choose the lower concentration which also can reach the same dyeing uptake to check the connection of completion time and tempreature.

According to this experimental result, CD series pigment paste dyeing in higher temperature is better for reducing of residue concentration after high concentration dyeing. But we can find that over high dyeing liquid temperature will cause color creases on dyed fabric. So the low temperature is needed at the beginning of dyeing process, to avoid bigger dyeing uptake and unevenly dyeing. Now we can know that CD series cationic pigment paste dip dyeing would make uniform heating way of first low and ther high, and heating temperature should not be too high. The dyeing process is just uniform heating and then heat preservation.

Dyeing principle of CAISON CD series cationic water based pigment paste, is the pigment fine particles are being on competitive situation of textile fibers electrostatic interaction and water surface tension during the textile dyeing process. When the electrostatic force is greater than the surface tension, the pigment fine particles will be adsorbed on the textile fibers. When textile fiber is fully absorbed by pigment particles, the diffusion movement of pigment particle is more intense, pigment particle is easily released from the fabric. If higher temperature, this phenomenon is more obviously. So the temperature holding time of the dip dyeing should not be too long.

2. Dyeing bath ratio confirmation.

The dyeing bath ratio is the key point that pigment dyeing paste and textile fiber can reach the equilibrium concentration. Controlling the dyeing bath ratio is very important for textile dyeing effect. This experiment is to test the ratio and each amount of CD cationic pigment paste, water and textile fabric in the dyeing process.

CD series cationic pigment paste is the same as reactive dyes, dyeing ratio has a certain influence on the dyeing depth of textile fabrics.

When the pigment paste amount is a certain, the dyeing uptake will decrease along with the bath ratio is increasing, and the residual pigment paste amount will increase based on it. For the dyeing levelness, when bath ratio is lower, dyeing is unevenly. And the bath ratio reaches 1:30, the dyeing liquid is almost colorless when dyeing is finished. 

So the conclusion of this testing is that the reasonable dyeing bath ratio is 1:30 for CD series cationic water based pigment paste.

Study of CAISON P series pigment paste in natural latex application

The summarization: this paper introduces the application of latex colorant ( P series pigment paste) in production of natural latex goods.

Keywords: water-based pigment paste, natural latex, CAISON, P series pigment paste.

In the natural latex products industry, latex balloons and latex gloves have a large proportion, the industry competition is fierce. How to reduce producing costs? How to improve the fastness and quality of latex products? Every manufacturer should think about it. Especially in the coloring step, how to choose and use eco-friendly water based pigment paste? 

Affecting factors of the quality of latex products

Grade and Quality of latex products is mainly determined by following factors: raw latex quality, latex vulcanizing process control, colorant choice, after-treatment of products and etc. Among them, the real greater impacts on product quality is latex vulcanizing process and colorant using.

Latex products coloring

For the coloring of latex products, so many factories still use the old way of "dry powder coloring", just mix the pigment powders and latex materials to stir, and the pigment powders are processed by rough grinding and dispersing.  And you should know the latex coloring is key factor in latex product quality. 

Actually, preparation of dry pigment powder formulation is too simple, production equipment is is relatively backward.Even if making dozens of hours grinding and stirring, the fineness and color strength of pigment paste still hard to be greatlly improved, and poor storage stability. It easily casuses precipitation phenomena, just can be produced when needing at the moment.

In order to meet the requirement of latex product customers, Shanghai Caison has developed the P series water based pigment color paste for natural latex tinting. This series pigment paste has higher concentration, pure colors, bright color shade, extensive chromatography and excellent compatibility with natural latex system. From the P series pigment paste introduced to now, CAISON P series latex tinting pigment paste reaches the higher quality and grade requirement from customers.

When the water based pigment paste is used in the latex system, it can provide bright colors and excellent brightness for latex products. First,  pigment paste must has vey good compatibility with latex materials, otherwise, it will cause uneven color, poor brightness and other problems.So when we design the P series latex tinting pigment paste formulation, we should make some compatibility testings between selected additives and latex materials, to avoid various problems because of bad compatibility.

At the same time, water-based pigment paste should reach the best dispersion degree before applied in latex system. Not only it can avoid latex agglutination because of big particles pigment, but also can improve higher color strength, bright shade and excellent brightness.

CAISON P series water based pigment paste is produced with high quality raw material, an unique formulation and advanced process equipment, the pigment paste fineness is up to less than 4 microns, most of them is less than 2microns. So P series pigment paste has a good storage stability, vividness and brightness is much higher than the "dry pigment powders".

The proportion of latex tinting pigment paste in whole latex system is not big, but its performance will directly affect the quality and grade of latex products, the users should pay sufficient attention to it.

Why do we insist on developing new type textile cationic dyeing pigment paste?

Lead： Textile printing and dyeing industry is a major water user. The traditional printing and dyeing of dyestuffs has complex process and poor coloring rate, a large amount of wastewater with various organic materials and salt are produced during the process of printing and dyeing. This will pollute the environment, is a big problem of wastewater treatment. Along with the increasingly stringent on environmental requirements, waste water controlling has become an important factor restricting the further development of printing and dyeing industry.

1. Comparison of textile dyeing process

Reactive dyes, 1980s traditional water based pigment paste, (new) textile cationic dyeing water based pigment paste CD series.

In recent years, more and more textile printing and dyeing factories are urgently finding more simpler and environmental dyeing ways because of production costs and environmental protection pressure. In the textile dyeing industry, everyone knows pigment dyeing is more eco-friendly than dyestuffs dyeing.

Traditional pigment textile dyeing needs modifying treatment in order to make pigment particles adsorbed on the textile. Before pigment dyeing, textile needs cationic grafting treatment, heating, so that the textile fibers connected to the cationic groups and needs cleaning, cleaning excess cationic grafting agents!

Shanghai Caison Color had developed the new water based pigment paste in three years, it is CD series textile cationic dyeing water based pigment paste, to make dyeing process simpler and environmental.And this new product is in line with the requirement of reducing costs and wastewater consumption.

2. Characteristics and advantages of CD series textile cationic dyeing pigment paste

1). Use CD series pigment paste to dyeing gray fabric and garment, no cationized (graft) pre-treatment needed, just one-pot direct dyeing, it can shorten dyeing working time by 30% or above, save costs by 20%, reduce wastewater discharging by 40%, so it can improve prodcution efficiency, conforming to the low-carbon economy development.

2). CD series water based pigment paste is suitable for dyeing cotton, hemp, silk and other gray fabrics, higher dyeing rate of garment dyeing;

3). Dyeing depth is Medium color or light color,  almostly can reach complete dyed. It can achieve dyed water colorless as long as appropriate bath ratio.
