Problems solved by technology

[0006] The water transfer printing paper prepared by the existing water transfer printing technology is composed of multiple layers, and the base layer is the original paper layer. In order to improve the stiffness, uniformity and smoothness of the paper, it is necessary to add a coating layer on the basis of the original paper. In addition, the square meter weight and thickness requirements of base paper are also relatively high. The preparation process of water transfer printing paper has the technical problems of long preparation process, large product thickness and gram weight, and high preparation cost.

preparation example Construction

[0034] figure 1 It is a method flow chart of a method for preparing non-woven water transfer printing paper shown according to an exemplary embodiment, such as figure 1 As shown, the method includes:

[0035] Step (1): The coniferous wood pulp board with a brightness of 85%-88% is sequentially subjected to hydraulic opening treatment and mechanical beating treatment to obtain a wood pulp slurry with a concentration of 3.0-3.4%, and the wood pulp slurry is sent to the distribution After the pulp pool is evenly mixed, dilute with water to reduce the concentration of the wood pulp slurry to 0.08-0.12%, control the pulp-net speed ratio to 0.85-0.88, the frequency to 110-150 times / min, and the amplitude to 8-11mm. The weight is 40-60g / m after being formed by the net former 2 wood pulp fiber web layer.

[0036] Among them, hydraulic opening treatment can obtain wood pulp fibers with longer length, and mechanical beating treatment can further increase the subsequent entanglement p...

Embodiment 1

[0055] (1) Preparation of the wood pulp fiber web layer: after the coniferous wood pulp board with a brightness of 85% is subjected to hydraulic opening treatment and mechanical beating treatment, a wood pulp slurry with a concentration of 3.0% is obtained, and the wood pulp slurry is sent into After mixing evenly in the pulp mixing tank, dilute with water to reduce the concentration of the wood pulp slurry to 0.08%, control the pulp net speed ratio to 0.88, the frequency to 150 times / min, and the amplitude to 11mm, and form it with an inclined wire former to obtain the grammage 40g / m 2 The wood pulp fiber web layer, wherein, the hydraulic opening treatment process comprises: carry out hydraulic opening treatment pulverization to described coniferous wood pulp board and obtain wood pulp slurry, the length of wood pulp fiber in the described wood pulp slurry is 5mm, and width is 60.8 μm, the pulping concentration is controlled to be 3.0% during the hydraulic pulping process, an...

Embodiment 2

[0063] (1) Preparation of the wood pulp fiber web layer: after the coniferous wood pulp board with a brightness of 87% is subjected to hydraulic opening treatment and mechanical beating treatment, a wood pulp slurry with a concentration of 3.2% is obtained, and the wood pulp slurry is sent into After mixing evenly in the pulp mixing tank, dilute with water to reduce the concentration of the wood pulp slurry to 0.10%, control the pulp net speed ratio to 0.86, the frequency to 130 times / min, and the amplitude to 10 mm, and form it with an inclined wire former to obtain the grammage 50g / m 2 The wood pulp fiber web layer, wherein, the hydraulic opening treatment process comprises: carry out hydraulic opening treatment pulverization to described coniferous wood pulp board and obtain wood pulp slurry, the length of wood pulp fiber in the described wood pulp slurry is 3mm, width is 52.1 μm, the pulping concentration is controlled to be 3.2% during the hydraulic pulping process, and t...

Abstract

The invention discloses a non-woven water transfer printing paper and a preparation method thereof, and relates to the cross technical fields of textile and water transfer printing. A kind of non-woven water transfer printing paper provided by the present invention and its preparation method, through the reasonable selection of wood pulp fiber, polylactic acid bicomponent fiber and polylactic acid fiber, and the selection and regulation of special double-layer fiber network structure, water The adjustment of thorn reinforcement and thermal pressure setting process, and the creative application of non-woven fabrics in water transfer printing technology, makes the prepared non-woven water transfer printing paper not only have excellent strength, but also have good size, It is not easy to curl in water, the product thickness and grammage are small, the preparation process is short, the preparation cost is low, and the technical effect of safety and environmental protection is achieved.

Description

technical field [0001] The invention relates to the cross technical field of textile and water transfer printing, in particular to a non-woven water transfer printing paper and a preparation method thereof. Background technique [0002] Water transfer printing technology uses the pressure of water to dissolve and transfer the peeling layer on the water transfer printing carrier, so that the pattern is transferred to the surface of the substrate. The principle of indirect printing solves the decoration and printing problems of many special-shaped surfaces. Among them, the water transfer printing carrier is usually made of special paper, which plays a very critical role in the water transfer printing process. People use water transfer printing paper to transfer the pattern to the surface of the substrate of special shape and material, such as ceramics, metal, wood, Cloth, glass, plastic, crystal, etc., do not need the complicated processes of steaming, color fixing and washing...
