Embodiment 1

[0024] The erasing cloth in this embodiment is used for wiping the black ash on the surface of the tinplate with a coating thickness of 1.1-2.8 thickness. For this tinplate, the coating is not easy to be scratched due to the thin coating thickness. The main consideration is to wipe the dust effect, its formula and production process are:

[0025] The content of cotton in the wiping cloth is 75%, wool fiber contains 5%, chemical fiber contains 20%, and chemical fiber adopts polyester fiber;

[0026] The fiber blending containing the above-mentioned components is spun out of a spindle, and a gray cloth is woven into a gray cloth by a circular weft machine. The thickness of the gray cloth is controlled at 1.2 mm, and the gray cloth is singed;

[0027] The woven gray fabric is softened by an overflow machine. The softener used for softening contains 5% emulsion type high-temperature softener, 2% inorganic antistatic agent, 1% penetrating agent, 1.5% fluorosilane coupling agent, an...

Embodiment 2

[0033] The erasing cloth in the present embodiment is used for coating thickness to be greater than the black ash of 2.8 thickness tinplate surfaces to wipe, for this tinplate, because the thickness of tinplate is big, coating is easy to produce scratch, so mainly will consider wiping In addition to the softness of the cloth, its formula and production process are:

[0034] The content of cotton in the wiping cloth is 90%, wool fiber contains 0%, chemical fiber contains 10%, and chemical fiber adopts polyester fiber;

[0035] The fiber blending containing the above-mentioned components is spun out of a spindle, and a gray cloth is woven into a gray cloth by a circular weft machine. The thickness of the gray cloth is controlled at 1.5 mm, and the gray cloth is singed;

[0036] The woven gray fabric is softened by an overflow machine. The softener used for softening contains 10% emulsion type high-temperature softener, 2% inorganic antistatic agent, 1% penetrating agent, 2.0% fl...

Embodiment 3

[0040] The erasing cloth in this embodiment is used for erasing the black ash on the surface of the secondary cold-rolled tinplate, usually the black ash on the surface of the secondary cold-rolled tinplate is more serious than the black ash on the surface of other types of substrates, so The factor to be considered is the dust absorption ability of the erasing cloth, and its formula and production process are:

[0041] The content of cotton in the wiping cloth is 85%, wool fiber contains 10%, chemical fiber contains 5%, and chemical fiber adopts polyester fiber;

[0042] The fiber blending containing the above-mentioned components is spun out of a spindle, and a gray cloth is woven into a gray cloth by a circular weft machine. The thickness of the gray cloth is controlled at 1.5 mm, and the gray cloth is singed;

[0043] The woven gray fabric is softened by an overflow machine. The softener used for softening contains 5% emulsion type high-temperature softener, 5% inorganic a...

Abstract

The invention discloses a wiping cloth for tin plate surface black ash and a manufacturing process thereof. The wiping cloth for the tin plate surface black ash is blended with cotton, wool and chemical fiber, wherein the content of cotton is 60% to 80%, the content of wool fiber is 0 to 10%, and the content of chemical fiber is 10 to 40%; after the cotton, wool and chemical fiber are blended, a conventional ring spinning machine is used for obtaining a spindle, and then a circular weft knitting machine is used for weaving the gray fabric; after singeing and mercerizing the gray fabric, an overflow machine is used for performing softening treatment; the gray fabric is dipped twice and rolled twice in a far-infrared finishing liquid, and dried after rolling; and after the wiping cloth is softened, the edges are sizing for 1 to 5 mm to fix. The wiping cloth for the tin plate surface black ash disclosed by the invention has softness, oil repellency and certain ash absorption, and can absorb the black ash wiped off when wiping the surface of the tin plate; meanwhile, the wiping cloth for the tin plate surface black ash also has a certain elasticity, which meets the requirements of a ash wiping device to automatically transport the wiping cloth; and the wiping effect of the wiping cloth is good, and at the same time, the oil film on the surface of the tin plate cannot be damaged during the wiping process, and the scratches cannot be generated.

Description

technical field [0001] The invention relates to the field of fiber-cotton blended cloth, in particular to an erasing cloth for black ash on the surface of a tinplate and a manufacturing process thereof. Background technique [0002] Tinplate is an important food packaging material. People's living standards are improving day by day, and the application range and consumption of tinplate are increasing day by day. At the same time, people have higher and higher requirements on the quality of tinplate, especially the surface quality of tinplate. [0003] Black ash on the surface of tinplate is a major surface defect of tinplate. The formation of this kind of black ash is related to the characteristics of the production process of tinplate. At present, it is impossible to prevent the formation of black ash by changing the production process conditions. Therefore, only physical methods can be used to erase this layer of black ash on the surface of the tinplate. The structure ...
