Currently we habitually refer to plush toys as plush toys. For a long time, the biggest problem affecting the sales and recovery of plush toys is easy adsorption of dust and bacterial breeding. During playing, the children chew or even swallow the toy through skin contact, eye contact and chewing, so that certain dust adhered to the fluff is sucked into the lungs or certain bacteria are mistakenly eaten into the body, and the health development of the children is adversely affected. In addition, plush toys are discarded during long play because the surface fills with dirt, and toy factories often refuse to recover because of these hard to handle dirt.

At present, no special plush toy cleaning agent exists in the market, and a laundry detergent is generally used for washing, but because a large amount of filling materials are contained in the plush toy, the moisture is difficult to volatilize completely, bacteria and mould are easy to propagate and breed, and the plush toy is unfavorable for health; the toy is easy to deform, the surface is hardened, and the plush is not fluffy after washing; chemical synthetic substances and essence residues in the liquid laundry detergent can cause certain irritation to the skin of children, have potential safety hazards and pollute the environment.

Salt (namely sodium chloride) is used as the most common seasoning in daily diet, so that the food has salty taste, low price and high safety, and has obvious adsorption effect on dirt. The project is to re-wrap and crystallize large-particle salt and substances such as plant surfactant, natural herbal extract or natural antibacterial factors through a wet coating technology, efficiently remove stains while not reducing the adsorption capacity of the salt, continuously inhibit bacteria, have mild formula, avoid water washing, greatly reduce potential safety hazards, and can be used in combination with a cleaning device to rapidly and efficiently treat toy stains.

3. Detection result

TABLE 2 influence of the number of edible salt on the cleaning effect of plush toys

As can be seen from Table 2, the number of edible salt has a significant effect on the cleaning effect of the plush toy. When the mesh number of the edible salt is more than 80 meshes (the mesh number is large, the corresponding granularity is small), the auxiliary materials can be effectively and uniformly attached to the surfaces of the edible salt particles due to the large specific surface area of the edible salt, so that the auxiliary materials are high in attachment rate and good in decontamination capability, but the particle size of the product is too small, dust emission is easy to occur in the preparation process and the cleaning and using process of the product, and the product is not easy to fall off from plush gaps in the cleaning process, so that the residual rate is high after dry cleaning, and plush is hard and knotted; as the mesh number of the edible salt is reduced, namely the corresponding granularity is increased, the dust emission is weakened, the residual rate is reduced, the softness is increased, and the comprehensive cleaning effect of the product is optimal when the mesh number is 14-30 meshes; however, when the mesh number is continuously reduced, the granularity of the edible salt is too large, so that the product cannot fully enter between the floss gaps on the surface of the plush toy, and other auxiliary materials are difficult to effectively wrap on salt particles in the preparation process of the product or are easy to fall off after wrapping, so that the adhesion rate of the auxiliary materials of the product is reduced, the detergency is reduced, and the efficacy of the product is affected.

Example 13

The dry cleaning salt of the present invention has a cleaning effect and skin irritation.

1. Experimental materials

Preparing a sample to be cleaned: preparing a plurality of plush toys with the same specification, wherein the plush toys are plush Teddy bear, and the size of the plush toys is 40cm long, 20cm wide and 20cm high (based on the outer packing size); and (3) selecting a sunny day, and placing the plush toy in an open air environment for 3 days so that the plush Teddy Xiong Ziran is adhered with pollutants such as dust, soil, bacteria and the like to serve as the plush toy to be cleaned.

Preparation of a cleaning agent: sample 1 is a commercially available general cleaner (laundry detergent), sample 2 is a commercially available general dry cleaning powder (cloth dry cleaning powder), and sample 3 is a product prepared in example 9 of the present invention.

2. Experimental method

The method for using sample 1 is: dissolving the sample 1 in water, soaking for 30min, rubbing, rinsing for 3 times according to the common cleaning habit, and spin-drying or wringing; typically 30 kg of water is added to 30mL of laundry detergent.

Sample 2 application method: and uniformly spreading the sample 2 on the plush toy, reversely rubbing the wool by using a bath brush for a few minutes, and after the washing is finished, brushing dry-cleaning powder by using a comb.

The using method of the sample 3 is carried out by adopting the method of the embodiment 11, placing the plush toy to be cleaned in a sealable container, adding dry cleaning salt according to the mass ratio of the plush toy to the dry cleaning salt of 3:1g/g, rapidly overturning the sealed container for 5min, pouring out, shaking the plush toy, and shaking the residual dry cleaning salt on the plush toy.

3. Detection index

(1) Cleaning ability and fixation ability: selecting 12 product experimenters to form an assessment group, observing and judging the decontamination capability, softness and color fixing capability of the plush toy cleaned by using three groups of products, scoring according to the scoring standard of the table 1, and then taking an average value, wherein the measurement method is the same as that of example 12;

(2) Skin irritation: the back and spine sides of the test animal are sheared off by the hair before the test, the hair removing range is 3cm multiplied by 3cm respectively, 1g (mL) of the test object is uniformly coated on the skin with the area of 2.5cm multiplied by 2.5cm, four layers of gauze are coated on the skin after the coating, then a layer of non-stimulated plastic film is used for covering, and then the non-stimulated adhesive tape is used for fixing. The other side of the dehaired skin was used as a negative control with sterilized normal saline. After 12h of application, the residue was removed by washing with water. The coating is applied once a day for 14 days continuously, and the conditions of red spots, edema and the like of the coating part are observed and recorded by naked eyes.

Table 3 comparison of cleaning effect and skin irritation of dry cleaning salt for plush toy with conventional method

As is clear from Table 3, the dry cleaning salt for plush toys according to the present invention has little difference in detergency from the conventional cleaning agents and dry cleaning powders on the market, but is excellent in softness after washing, color fixing ability and skin irritation effect. This is due to the fact that in the commercial general cleaners, certain chemical reactions between the detersive ingredients and the dye occur during the cleaning process, resulting in slight discoloration; in addition, the common cleaning agent needs to be cleaned by adding water, so that the cleaning agent can be removed by rinsing, and the residual quantity of the cleaning agent is smaller after the conventional rinsing for 3 times in the embodiment, so that the skin irritation is smaller; the common dry cleaning powder sold in the market is easy to remain and cause irritation to skin due to fine powder, and the phenomena of redness, swelling and the like are generated.
