Problems solved by technology

[0004] The above existing technical solutions have the following defects: the adhesive coated on the flocking paper generally needs to have a certain consistency to ensure the stability of the adhesive on the flocking paper and to ensure that the adhesive is not easy to flow during the flocking process In addition to flocking paper, it is usually necessary to add a thickener to the adhesive. However, the main component of the existing thickener is polyurethane, which is extremely difficult to degrade and easily pollutes the environment. Therefore, there is still room for improvement.

Embodiment 1

[0082] A production process of a biodegradable electrostatic flocking paper product, comprising the following steps:

[0083] S1, cutting, as follows:

[0084] The lyocell fibers are cut into short fibers with a length of 0.4-0.5 mm using a cutting machine.

[0085] S2, dyeing, specifically as follows:

[0086] Add 50kg of short fibers into the dyeing vat, and add 180kg of water into the dyeing vat, and stir and mix evenly at a speed of 200r / min. After adding water for 5 minutes, add 5 kg of substitute alkali while stirring, and add it after adding substitute alkali for 5 minutes. Stir again Add 12.5 kg of reactive dyes, and then feed steam into the dyeing vat while keeping stirring, so that the temperature of the mixture in the dyeing vat increases at a rate of 0.5°C / min. When the temperature in the dyeing vat rises to 50°C, keep The temperature in the dye vat is 50°C, keep warm for 60 minutes, and then discharge the dye solution in the dye vat.

[0087] Then add 100kg of ...

Embodiment 2

[0103] The difference with embodiment 1 is:

[0104] The consumption of each component in the step S2 is as follows: short fiber 50kg; water 190kg; substitute alkali 4kg; reactive dye 15kg. And the temperature in step S2 is raised to 60° C., and the dye solution is discharged after being kept warm for 55 minutes.

[0105] The dosage of each component in step S3 is as follows: water glass 0.4kg; softener 1.5kg; aluminum acetate 0.8kg; silica sol 1kg; magnesium sulfate 1.5kg. And the temperature in step S3 is increased to 40° C., and finally kept for 10 minutes.

[0106] The dosage of each component of the adhesive in step S6 is as follows: polylactic acid 82.5kg; sodium hydroxymethylcellulose 2kg; chitosan 0.75kg.

Embodiment 3

[0108] The difference with embodiment 1 is:

[0109] The consumption of each component in step S2 is as follows: short fiber 50kg; water 200kg; substitute alkali 3kg; reactive dye 10kg. And the temperature in step S2 is raised to 70° C., and the dye solution is discharged after being kept warm for 50 minutes.

[0110] The dosage of each component in step S3 is as follows: water glass 0.3kg; softener 1kg; aluminum acetate 0.4kg; silica sol 0.5kg; magnesium sulfate 1kg. And the temperature in step S3 is raised to 45° C., and finally kept warm for 5 minutes.

[0111] The amount of each component of the adhesive in step S6 is as follows: 85 kg of polylactic acid; 1 kg of sodium hydroxymethyl cellulose; 0.5 kg of chitosan.

Abstract

The invention relates to the technical field of electrostatic flocked products, and concretely relates to a production process of a biodegradable electrostatic flocked paper product. The production process comprises the following steps: S1, cutting; S2, dyeing; S3, electro-deposition treatment; S4, drying; S5, screening; S6, gluing; S7, flocking; and S8, drying. Added substances comprise, by mass,50 parts of short fibers, 180-200 parts of water, 10-15 parts of a reactive dye, 3-5 parts of a substituted alkali, 1-2 parts of magnesium sulfate, 0.5-1 part of silica sol, 0.4-0.8 part of aluminumacetate, 1-2 parts of a softening agent and 0.3-0.5 part of water glass; and an adhesive comprises, by mass, 80-85 parts of polylactic acid, 1-3 parts of sodium carboxymethyl cellulose and 0.5-1 partof chitosan. The electrostatic flocked paper has the effect of facilitating good biodegradation of the electrostatic flocked paper product.

Description

technical field [0001] The invention relates to the technical field of electrostatic flocking products, in particular to a production process of biodegradable electrostatic flocking paper products. Background technique [0002] At present, electrostatic flocking paper products have been widely used in various countries because of their unique decorative effects of suede and embroidery, as well as the characteristics of simple process, low cost and strong adaptability. [0003] Existing electrostatic flocking paper products use the physical characteristics of same-sex repulsion and opposite-sex attraction to make the fluff negatively charged, and put the flocking paper that needs to be flocked under zero potential or grounding conditions, and the fluff is charged by the different potential. The flocking paper attracts and accelerates vertically to the flocking paper that needs to be flocked. Since the flocking paper is coated with adhesive, the fluff is vertically stuck on th...
