Description
Technical Field
The invention relates to the technical field of clothing accessories, in particular to a glue dipping slurry, a glue dipping rope end and a preparation method thereof.
Background
The rope head is a common clothing accessory and is widely applied to clothing such as clothes, shoes and hats. Along with the fashion trend of clothes and the mass aesthetic sense, people have more and more appearance requirements on clothes, and abundant varieties are derived from the rope ends, wherein the rope ends with the color-embossed effect are obvious in randomness and natural properties, and various DIY elements are easily blended by adjusting the color, the number and the size of the embossing on the surface of the rope ends, so that the personalized requirements of people on clothes are met, and the rope has a good application market.
The rope ends are usually prepared by spraying or dipping, but both methods have defects. The spraying method can realize the mutual mixing and stringing of different colors, one color is sprayed at one time, the effect of multiple colors is realized by spraying for multiple times, and the raised irregular spots are formed by adjusting the viscosity of the spray gun and the ink. However, the sprayed droplets are easy to deform and flow after being sprayed at a certain speed and impacting a substrate, so that the raised spots are in a star shape instead of a nearly circular shape, if the atomization degree of the spray gun is improved, the spots formed by partial surface drying of the droplets in the flight process can be relatively circular, but the spots are difficult to have stereoscopic impression due to too small droplets. Therefore, the rope head prepared by adopting the spraying method can realize multicolor effect only by multiple times of spraying, the steps are complicated, the atomization degree of the spray gun is difficult to control, and the embossing effect is poor.
The dipping rope head is prepared by adopting a dipping method, the trouble of spray gun atomization degree can be avoided through the dipping mode, but the multi-color effect can be realized only through one-time dipping and coating of one color, so that the dipping rope head is very inconvenient, and the prepared dipping rope head has obvious boundaries among different color layers, is expressed as one section of one color and has poor effect. In addition, the existing impregnation sizing agent is difficult to realize the relief effect of the impregnated rope head.
