Embodiment 1

[0022] A method for manufacturing a flushable wet tissue paper base paper, comprising the following steps:

[0023] a. Papermaking process: after the pure wood pulp is disintegrated by a hydropulper, it is disintegrated and beaten to obtain a wood pulp slurry with a concentration of 2.5 wt% and a degree of percussion of 18oSR; Mix with wood pulp slurry in the pulp tank, and finally prepare papermaking slurry consisting of 35% wood pulp fiber, 25% polylactic acid fiber, and 40% coconut charcoal fiber according to the dry pulp ratio, and the concentration of papermaking slurry is controlled at 1.5 wt % Add papermaking special dispersant accounting for 0.5% of the total weight of papermaking slurry to the papermaking slurry for batching, then pass through the inclined wire papermaking wire part former, press dehydration, and dry the base paper to obtain the base paper;

[0024] b. Spunlace entanglement process: The base paper obtained in the papermaking process is treated with sp...

Embodiment 2

[0028] A method for manufacturing a flushable wet tissue paper base paper, comprising the following steps:

[0029] a. Papermaking process: after the pure wood pulp is disintegrated by a hydropulper, it is disintegrated and beaten to obtain a wood pulp slurry with a concentration of 2.5 wt% and a degree of percussion of 18oSR; Mix with wood pulp slurry in the pulp tank, and finally prepare papermaking slurry consisting of 30% wood pulp fiber, 28% polylactic acid fiber, and 42% coconut charcoal fiber according to the dry pulp ratio, and the concentration of papermaking slurry is controlled at 1.5 wt % ; Add papermaking special dispersant accounting for 0.6% of the total weight of papermaking slurry to the papermaking slurry for batching, then pass through the inclined wire papermaking wire part former, press dehydration, and dry the base paper to obtain the base paper;

[0030] b. Spunlace entanglement process: the base paper obtained in the papermaking process is spunlace enta...

Embodiment 3

[0034] A kind of manufacturing method of the base paper of flush type wet tissue paper, specifically is the following steps:

[0035]a. Papermaking process: after the pure wood pulp is disintegrated by a hydropulper, it is disintegrated and beaten to obtain a wood pulp slurry with a concentration of 3.0 wt% and a degree of percussion of 20oSR; Mix with wood pulp slurry in the pulp tank, and finally prepare papermaking slurry consisting of 35% wood pulp fiber, 25% polylactic acid fiber, and 40% coconut charcoal fiber according to the dry pulp ratio, and the concentration of papermaking slurry is controlled at 1.2 wt % Add papermaking special dispersant accounting for 0.5% of the total weight of papermaking slurry to the papermaking slurry for batching, then pass through the inclined wire papermaking wire part former, press dehydration, and dry the base paper to obtain the base paper;

[0036] b. Spunlace entanglement process: the base paper obtained in the papermaking process i...

Abstract

The invention relates to a production method for a nonwoven material, in particular to raw paper for dispersed wet tissues and a production method for the raw paper. The raw paper for the dispersed wet tissues is a nonwoven material obtained by sequentially executing a papermaking procedure, a spunlace entanglement procedure and a dehydration drying procedure on papermaking pulp consisting of 25 to 28 weight percent of polylactic acid fibers, 40 to 42 weight percent of coconut coal fibers and the balance of wood pulp fibers, and does not contain any additional bonding agent and wet strength agent. According to the raw paper for the dispersed wet tissues and the production method, a gap in a production technology for the raw paper for the dispersed wet tissues in China is supplied, foreign and domestic market requirements are met, and a conventional raw paper production process is simplified; papermaking is combined with spunlace, so that the production cost is lowered, and the wet strength, wet wiping effects and hydrolytic property of the raw paper for the dispersed wet tissues are importantly improved; an obtained product is high in dispersibility and biodegradability.

Description

technical field [0001] The invention relates to a production method of a non-woven material, in particular to a base paper of a flushing type wet tissue paper and a production method thereof. Background technique [0002] In the past two decades, the non-woven fabric industry has developed rapidly and technology is changing with each passing day. Non-woven fabric industrial products have entered thousands of households, especially in developed countries in Europe and the United States with high consumption levels. Dry and wet wipes, female sanitary napkins, children's diapers, etc. made of non-woven fabrics have entered people's daily life because of their low price, convenience, practicality, cleanliness and sanitation. However, the currently used non-woven fabric products, especially the wet wipes used in wet conditions, if discarded in the toilet, will block the bottom hole of the toilet, household drainage pipes and urban sewage pipe systems, which will bring inconvenien...
