A preparation device for cohesive sand grains used for fabric sand washing

Abstract

The invention discloses a preparation device for cohesive sand grains used for sand washing of fabrics, comprising: a screen and an injection mechanism facing the screen, characterized in that grooves are densely arranged on the screen, and openings on the grooves are The plane coincides with the screen plane, the upper opening of the groove can only pass through a single grain of sand, the lower opening of the groove is located at the bottom of the groove, and the diameter of the lower opening of the groove is smaller than the diameter of a single grain of sand. The depth direction of the recessed groove can only hold a single grain of sand at the same time; the injection mechanism is located on the side close to the lower opening of the groove, and the injection port of the injection mechanism can move, and the movement range of the injection port is as close as the screen mesh A parallel plane; the screen is provided with an air injection mechanism on the side facing the upper opening of the groove, and the air injection mechanism is obliquely sprayed towards the screen plane. The present invention can bond a small amount of sand grains regionally, reducing the The volume of the bonded sand block.

Description

technical field [0001] The invention relates to physical treatment and chemical treatment of fiber products. In the invention, mechanical operation and biochemical treatment of polymer compounds work together to process fiber fabrics, especially a preparation device for cohesive sand grains used for fabric sand washing. Background technique [0002] Cotton polyester refers to the fabric blended with cotton and polyester fibers, with cotton as the main component. Cotton polyester blends are made of cotton as the main component, using 65%-67% cotton and 33%-35% polyester blended fabrics. Textiles, cotton polyester cloth is commonly known as cotton polyester, which is the opposite of polyester cotton. Polyester cotton is a mixture of polyester and cotton, which is not as comfortable as cotton. It is not as sweat-absorbing as cotton. Polyester is the largest variety with the highest output among synthetic fibers. Polyester has multiple trade names, and "polyester" is a common...

Problems solved by technology

[0004] However, in the existing sand washing process, the size of the sand particles is difficult to be effectively controlled, and the obtained bonded sand block is too large in size to achieve accurate bonding of two or three sand particles, which limits the development of the sand washing industry to a certain extent.
