Description
[technical field]
The invention belongs to pulp technology for making paper, and in particular to a kind of toilet paper prepared using bleaching process.
[background technique]
The production method of paper pulp mainly includes the productions stream such as chemical method, semichemical method, Mechanical Method and chemical mechanical pulping at present
Journey.Wherein chemical pulping is occupied an leading position among current numerous pulping process.Claim by paper pulp made from chemical method boiling
For true qualities paper pulp, true qualities paper pulp limits its application since whiteness is lower, and true qualities paper pulp will could generally give birth to after bleaching
Produce the paper kind of higher level.
Paper for daily use, particularly toilet paper are a kind of common daily consumption articles, still, in psychologically to whiteness
It needs and the demand to some physical indexs, generallys use the pulp manufacture based on bleached wood pulp.Even if being starched using herb
Prepare toilet paper, also all use bleached pulp, however gained paper pulp yield and whiteness are still lower, the brightness of toilet paper, tensile index,
Pliability is not also high.
With the continuous expansion of paper industry, constantly opening up for pulp applications is wide, originally the wood as main paper making raw material
Gradually supply falls short of demand for material, and forest is caused excessively to be cut down, and influences ecological environment, therefore, it is necessary to seek new raw material substituent.
Sinocalamus latiflorus (Dendrocalamus latiflorus Munro) is that south China cultivates most wide one of bamboo kind, is standing grain
Undergraduate course (Poaceae) Bambusoideae (Bambusoideae) Dendrocalamus (Dendrocalamus) large-scale sympodial bamboo kind, is distributed mainly on
The provinces and regions such as Fujian, TaiWan, China, Guangdong and Guangxi Provinces, Yunnan, Hainan, Sichuan, the Guizhou middle and south are protected for edible, material use, Ye Yong, water and soil
It holds, afforest the multipurposes bamboo kind such as ornamental, to produce bamboo shoot or do based on pulpwood.Sinocalamus latiflorus growth is fast, the bamboo shoot phase is long, yield is high, bamboo shoot are of fine quality
Good, sinocalamus latiflorus fast growing is widely used, and primary plant utilizes for many years, is that a kind of economic value is high, excellent calculation profitable on ecology
The dual-purpose bamboo kind of material, economic benefit, ecological benefits and social benefit Three benefits are significant.
Therefore be conducive to avoid result in forest and excessively cut down as wood raw material is replaced using artificial growth sinocalamus latiflorus, influence
Ecological environment.
