Description

Green food-grade detergent for textile printing and dyeing

Technical Field

The invention belongs to the field of textile printing and dyeing, and particularly relates to a green food-grade detergent for textile printing and dyeing, which takes original ecological food and food-grade substances as raw materials.

Background

After the dye on the dyed fabric is fixed through various conditions, the dyed fabric needs to be subjected to the treatment process of a detergent in a detergent process, so that the loose color, the sizing agent, the auxiliary agent and the like on the colored fabric are washed away. The detergent commonly used at present is mainly an anionic surfactant or a compound mainly comprising the anionic surfactant and a nonionic surfactant. The detergent has the defects of large using amount, poor biodegradability and the like.

The detergent is used for removing various impurities, dirt, auxiliaries, sizing agents and the like remained on fibers or fabrics thereof in the processes of printing, dyeing and post-finishing, and mainly comprises various types of surfactants. Many varieties of detergents supplied in the market at present contain or can generate chemical substances harmful to human bodies and ecological environments, serious ecological problems can be caused when people use the detergents, the products have high permeability and large residue in textiles and cause textile pollution, and when people wear textiles and clothes containing the residual harmful detergents, especially class A and class B clothes such as children clothes, underwear and the like, the harmful substances can enter the skin through pores to cause skin irritation, and further can be spread all over the body through microcirculation of capillary vessels to cause harm to human health.

Therefore, many countries and organizations internationally, particularly in the european union, have enacted regulations and regulations for banned and limited use textile detergents through ecological and toxicological studies of various detergents. Taking Eco-Label of European Union and Eco-Tex Standard 100 of International society for the study and testing of ecological textiles, which are currently the most influential, as an example, the former promulgated a new Standard for Eco-Label of European Union textiles in 2002, 5.15.2002, and the Standard for textile additives and chemicals specifically stipulates that 7 surfactants such as alkylphenol ethoxylate, linear alkylbenzene sulfonate, bis (hydrogenated tallow alkyl) dimethyl ammonium chloride, distearyldimethyl ammonium chloride, ditallow alkyl dimethyl ammonium chloride, ethylene diamine tetraacetic acid, diethylenetriaminepentaacetic acid, etc., and formulations or formulations composed of them are prohibited from being used. The problems of the above surfactants are mainly focused on their toxicity, poor biodegradability, environmental hormones and the production of harmful by-products during the production process. Because of the toxicity problem of the surfactants, the corresponding cleaning process needs two or more times of soaping, the soaping temperature is high, the single soaping time is long, the energy and water resource consumption is too high, the energy and water resource waste is caused, and the time consumption is longer.

Detergents are an important class of textile auxiliaries, whose ecological requirements, like other textile auxiliaries, are roughly eight as follows: high biodegradability, low toxicity, low or no formaldehyde, no environmental hormones, no more than a permissible limit of extractable heavy metals, no more than a permissible limit of 24 carcinogenic aromatic amines produced by cracking, no adsorbable organic halides, no other harmful chemicals. According to the requirements, most products in the market can not meet the requirements at present, so that the development of an environment-friendly, safe and energy-saving detergent is particularly urgent.

Disclosure of Invention

The invention provides a green food-grade detergent for textile printing and dyeing, aiming at the problems that the traditional detergent is not environment-friendly and has potential safety risk.

In order to achieve the purpose, the invention adopts the following technical scheme.

A green food-grade detergent for textile printing and dyeing comprises the following components in parts by mass:

100 portions of deionized water

4-8 parts of maltodextrin

4-6 parts of cane sugar

40-60 parts of glucose

Tween 806-8 parts

18-26 parts of alkyl glucoside

2-4 parts of potassium sorbate

4-8 parts of potassium hydrogen peroxymonosulfate.

The preparation method of the green food-grade detergent for textile printing and dyeing comprises the following steps:

(1) adding deionized water into a food-grade stainless steel reaction kettle, adding maltodextrin, sucrose and glucose under stirring, and uniformly stirring;

(2) slowly adding tween 80 into the step (1), uniformly stirring, adding alkyl glucoside, and stirring for 10 minutes;

(3) and (3) adding potassium sorbate into the step (2) and stirring uniformly, and then adding potassium hydrogen peroxymonosulfate and stirring uniformly to obtain the potassium hydrogen peroxymonosulfate.

The stirring speed in the step (1) is 80 revolutions per minute; the stirring speed in the step (2) and the step (3) is 30 revolutions per minute.

The alkyl glucoside in the detergent is a nonionic surfactant, has the advantages of high stability, no toxicity, high solubility, easy biodegradation, low irritation to skin and the like, and has good compatibility with Tween 80; the foam is fine and smooth, and the use of a defoaming agent can be reduced or avoided; and the viscosity is higher, and the viscosity, the adsorption and the impurity suspension capacity of the detergent can be increased by the detergent with maltodextrin, sucrose, glucose and the like. The potassium hydrogen peroxymonosulfate in the formula has strong oxidizing capability, the use and treatment process meets the requirements of safety and environmental protection, and no organic chlorine residue is caused; the water solution is acidic, and the detergent solution can be acidic without adding an acidic agent; is relatively stable in a normal state, and is easy to decompose when the temperature is higher than 65 ℃. In the post-treatment soaping process, the residual in the fabric can be eliminated by decomposing at high temperature.

The invention has the following beneficial advantages: various components of the detergent of the invention are harmless to human body; no pollution to the environment; strong hard water resistance; has excellent effect on pure cotton and polyester-cotton blended textiles, and can play roles in sterilization, softness, bright and bright color, antistatic property and the like. The detergent has better effect than the existing detergent, is widely applicable to various textile printing and dyeing processes, and has wide application prospect in the printing and dyeing industry.

Detailed Description

The present invention will be further illustrated with reference to the following examples, but the present invention is not limited to the following examples.

EXAMPLE 1 preparation of detergent

(1) Adding deionized water into a food-grade stainless steel reaction kettle according to the weight part ratio in the table 1, adding maltodextrin, sucrose and glucose under stirring, and uniformly stirring at the rotating speed of 80 revolutions per minute;

(2) slowly adding tween 80 into the step (1), uniformly stirring, adding alkyl glucoside, and stirring for 10 minutes; the rotating speed is 30 revolutions per minute;

(3) adding potassium sorbate into the step (2) and stirring uniformly, adding potassium hydrogen peroxymonosulfate and stirring uniformly, wherein the rotating speed is 30 revolutions per minute; thus obtaining the green food-grade detergent sample S1-S5 for textile printing and dyeing.

TABLE 1

EXAMPLE 2 soaping of textile printing detergent

The textile printing and dyeing detergents S1-S5 prepared in example 1 were respectively subjected to a washing process for textile cheese at a dye concentration ratio shown in Table 2, wherein the cheese was dyed at a bath ratio (weight ratio of textile to dye liquor) of 1: 5.

TABLE 2

As can be seen from the data in the table above, compared with the traditional detergent, the detergent of the invention has the advantages of less dosage, short single-time soaping time and low temperature, and can achieve the effect only by soaping for 1 time, thereby saving the process steps, time consumption and waste water amount of soaping and being more environment-friendly.
