Embodiment 1

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

[0026] 1) Preparation

[0027] ① Raw material preparation: Prepare 920Kg of peeled alpine bamboo yellow from Anji alpine bamboo, 228Kg of polyester fiber, and 296Kg of industrial grade calcium sulfate dihydrate whiskers by weight;

[0028] ②Auxiliary material preparation: prepare a sufficient amount of endo-β-1,4-xylanase aqueous solution, a sufficient amount of sodium hydroxide aqueous solution with a solute mass fraction of 10%-20%, and MJB-NS bamboo silk softener;

[0029] 2) Pretreatment

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

[0031] ② Completely immerse the bamboo strips obtained in step ① into the aqueous sodium hydroxide solution prepared in step 1) step ②, pressurize to 2 times to 2.5 times the atmospheric pressure and heat to boil at the same time, continue until t...

Abstract

The invention discloses a production process of digital printing base paper. The digital printing base paper uses 80-100 parts of peeled alpine bamboo yellow, 20-25 parts of polyester fiber, and 28-32 parts of phosphogypsum whiskers as raw materials ; Xylanase water, sodium hydroxide aqueous solution, MJB-NS bamboo silk softener as auxiliary materials, peeled alpine bamboo yellow is first boiled with water, modified, purified and bleached by a compound softener for two times of enzymatic decomposition, and three times of lightening. After carbonization compound activation treatment, it is hot-melted with other raw materials in a protective atmosphere. The invention has the advantages of high uniformity of fiber arrangement, good stiffness, high whiteness, water loss resistance, moderate electrical performance and smooth surface.

Description

technical field [0001] The invention relates to the technical field of papermaking technology, in particular to a production technology of digital printing base paper. Background technique [0002] The digital printing paper in the prior art has the following characteristics: In recent years, digital information technology has received unprecedented attention. New types of paper that serve digital information technology continue to emerge. The new digital printing coated papers that have been developed around the world mainly fall into the following categories: (1) Coated paper for electronic imaging printing—glossy full chemical pulp coated paper. (2) Coated paper for commercial digital printing (liquid coloring agent) printing—glossy full chemical pulp Xu cloth paper. (3) Coated paper used in inkjet printers - various inkjet printing papers. [0003] New paper requirements for digital printing: People may think of digital printing as non-contact printing. Pigment parti...
