Embodiment 1

[0025] A production process of digital printing base paper includes the following steps:

[0026] 1) Preparation

[0027] ①Preparation of raw materials: 920Kg of peeled alpine bamboo yellow from Anji alpine bamboo, 228Kg of polyester fiber, and 296Kg of industrial-grade calcium sulfate dihydrate whiskers are prepared by weight;

[0028] ② Preparation of auxiliary materials: prepare enough endo-β-1,4-xylanase water, enough solute mass fraction 10%-20% sodium hydroxide aqueous solution, MJB-NS type bamboo silk softener;

[0029] 2) Pretreatment

[0030] ①The peeled alpine bamboo yellow prepared in step 1) is mechanically cut into bamboo strips of (0.5mm-2mm)×(0.5mm-2mm)×(100mm-200mm);

[0031] ② Immerse the bamboo strips obtained in step ① into the sodium hydroxide aqueous solution prepared in step 1) step ②, pressurize it to 2 to 2.5 times the atmospheric pressure and heat to boiling at the same time, continue until the solid content in the solution is constant weight, take it out Solid ...

Embodiment 2

[0042] The whole is consistent with Example 1, the differences are:

[0043] A production process of digital printing base paper includes the following steps:

[0044] 1) Preparation

[0045] ①Preparation of raw materials: 800Kg of peeled alpine bamboo yellow, 250Kg of polyester fiber, and 320Kg of industrial grade calcium sulfate hemihydrate whiskers are prepared by weight;

[0046] ② Preparation of auxiliary materials: prepare sufficient α-L-arabinosidase aqueous solution, sufficient sodium hydroxide aqueous solution with a mass fraction of 10%-20% solute, and MB bamboo silk softener;

Embodiment 3

[0048] The whole is consistent with Example 1, the differences are:

[0049] A production process of digital printing base paper includes the following steps:

[0050] 1) Preparation

[0051] ①Preparation of raw materials: according to parts by weight, prepare 1000Kg of peeled alpine bamboo yellow, 200Kg of polyester fiber, and 280Kg of industrial-grade anhydrous calcium sulfate whiskers;

[0052] ② Preparation of auxiliary materials: prepare sufficient amount of α-D-glucuronidase water agent, sufficient amount of sodium hydroxide aqueous solution with a mass fraction of 10%-20% solute, and ZZB-NS type bamboo silk softener;

Abstract

The invention discloses a production process of digital printing base paper. The digital printing base paper is prepared from 80-100 parts of peeled high-mountain bamboo inner skin, 20-25 parts of polyester fibers and 28-32 parts of ardealite whiskers. A xylanase aqueous solution, a sodium hydroxide aqueous solution and an MJB-NS type bamboo filament softener are used as auxiliary materials. The peeled high-mountain bamboo inner skin is subjected to primary water boiling, secondary enzymatic decomposition, composite softener modification purification bleaching and third light-carbonization composite activation treatment, and then the treated peeled high-mountain bamboo inner skin and other raw materials are subjected to hot melting forming under a protective atmosphere. The base paper is high in fiber arrangement consistency, good in stiffness, high in whiteness, resistant to water loss, moderate in electrical performance and smooth in surface.

Description

Technical field [0001] The invention relates to the technical field of papermaking technology, in particular to a production process of digital printing base paper. Background technique [0002] Digital printing paper in the existing technology has the following characteristics: In recent years, digital information technology has received unprecedented attention. New paper types that serve digital information technology continue to emerge. The new digital printing coated papers that have been developed around the world mainly include the following categories: (1) Coated paper for electronic imaging printing-glossy full chemical pulp coated paper. (2) Commercial digital printing machine (liquid color former) printing coated paper-gloss full chemical pulp cloth paper. (3) Coated paper used in inkjet printers-various inkjet printing papers. [0003] New requirements for digital printing paper: People may think that digital printing is non-contact printing. Unaffected by the substr...
