Problems solved by technology

However, the softness and strength of paper products are just a pair of indicators that restrict each other in most of the existing domestic manufacturing processes. If you want to get better softness, the strength will be greatly lost. , and if you want to get better strength, softness will be sacrificed
On the other hand, at present, the few household paper companies that rank among the top in China are unable to achieve ideal results in the softness and strength of paper products due to cost or technical reasons.

Embodiment Construction

[0014] The manufacturing method for improving the softness of tissue paper of the present invention includes the steps of material selection, beating, filling, papermaking, scraping and pressing drying, and also includes selection and addition of a softener.

[0015] During the above material selection process, the raw materials and their weight contents are respectively 30%-40% of Canadian high-quality softwood kraft pulp, 30%-40% of Indonesian high-quality acacia fluff pulp, and 30%-30% of Brazilian high-quality eucalyptus fluff pulp. 40%.

[0016] During the above-mentioned beating steps, the pulp is decomposed by the deflaker before being refined by the refiner, and the concentration range of the pulp after decompression is controlled at 4.5% to 4.8%. The proportion of chemical, control the viscosity increase coefficient in the range of 1.2 to 1.3.

[0017] During the scraping process above, use the sharp-angled surface of the scraper to contact the surface of the dryer c...

Abstract

The invention discloses a manufacturing method for improving the softness of tissue paper. The method comprises the following steps of: sorting, pulping, filling, making paper, scraping the paper, squeezing and drying, and also comprises a step of selecting and adding a softener, wherein a fluffer and refiner series connection free pulping method is adopted and the range of a tackifying coefficient is strictly controlled in the pulping process, and an appropriate scraper angle is selected and the crepe ratio of the paper is adjusted in the paper scraping process. Compared with the prior art, the method has the advantages that: the softness and handfeel of a paper product are obviously improved while the paper product has high strength, the softness of paper towel raw paper is lower, the handfeel of the raw paper is better and the strength of the paper product is slightly influenced when processing conditions are met, and the satisfaction of a consumer with the product is obviously improved.

Description

technical field [0001] The invention relates to a paper production method, which belongs to the technical field of paper manufacturing, in particular to a production method for improving the softness of household paper. Background technique [0002] As we all know, an important focus of consumers on products such as paper towels and face towels is that paper products have good flexibility (that is, softness) and a certain dry and wet strength. In order to seize the dominant position in the market, the first thing is to make paper products cater to the concerns of consumers. However, the softness and strength of paper products are just a pair of indicators that restrict each other in most of the existing domestic manufacturing processes. If you want to get better softness, the strength will be greatly lost. , and if you want to get better strength, softness will be sacrificed. On the other hand, at present, a small number of tissue paper companies that rank among the best i...
