Description
Technical field
The present invention relates to a kind of terylene wood pulp wet tissues and preparation method thereof, belong to wet tissue technical field.
Background technique
The wet tissue market of sustainable growth and people constantly stimulate wet tissue product to health, health, the demand of environment-friendly products
Weed out the old and bring forth the new.At the same time, higher requirements are also raised for performance of the people to wet tissue spunlace non-woven material.Existing city
Wet tissue on face, which is generally formulated, to be produced for terylene viscose glue or full terylene as raw material, the rigid big, moisture absorption of polyester fiber
It is small, water conservation is poor, content excessively easily leads to product flexibility is poor, formulation absorption ability is poor, the resting period is short etc., therefore pure polyester production
Product are not typically used as wet tissue.
Become viscose glue terylene wet tissue by the way that a certain amount of viscose rayon is added, the hydrophilicity of terylene hydro-entangled non-woven fabric is big
It is big to improve, but when viscose glue content is greater than 10%, with the increase of viscose glue content, the mechanical property of terylene hydro-entangled non-woven fabric is bright
Aobvious decline；Strong stretching property, hard and soft and moisture absorbability and moisture retentivity are the important indicators for measuring wet tissue physical property.
Viscose glue and terylene do cost of material generally will be high, and manufacturing cost is high.In comparison wood pulp cellulose and polyester fiber
Compound wood pulp cloth formulation absorption ability is strong, and water retention property, mechanical property and moisture absorbability and moisture retentivity all improve a lot, while because of wood
Pulp fibres price is lower, and manufacturing cost is greatly reduced.
Chinese patent document CN106283839A (application number: 201610660119.0) is disclosed a kind of ultrashort using polyester
Fiber, wood pulp are by raw-material weight percentage by the spun lacing material of wet process water jet process machine-shaping for primary raw material
The wood by defibrination wire-dividing broom purification that the polyester superbhort fiber of 10-80%, the reinforced superbhort fiber of 0-5%, 15-90% are matched
Slurry mixes.Its forming method: wood pulp pulping rear sub-wire brooming, polyester superbhort fiber and reinforced superbhort fiber open liquid after packet
Mutually disperse, is then pierced in advance after the mixing of three's liquid phase, hygrometric state forming in titled net formation net, spun lacing, suction, drying, stain are examined
It surveys, coiled, cutting packaging after grammes per square metre detection.However, wood pulp cloth substitutes common wet tissue, there is also some problems, such as: wood pulp is fine
Dimension hplc excessively easily leads to that product flexibility is poor, and wet tissue thickness does not reach requirement, and later period packaging molding has been not easy to wrap.General wood
It starches in cloth production process in line with save the cost, reduces the principle of energy consumption, wringer is needed to carry out physics after platform spun lacing is compound
Dry, heated drying carries out dehydration and drying processing.But in order to make wood pulp cloth reach thickness requirement, reaches post-production packet as far as possible and want
It asks, squeezes the physics dehydration of mode, while dehydration, greatly reduce the thickness of product.It is applied alone steam-heated mode to carry out
Dry mode improves production cost firstly, steam consumption increases considerably, and produces speed critical constraints；Secondly heated drying
Temperature is excessively high, and drying too long in flow can make product hair shaft harden, and is not suitable for enhancing product performance.
Therefore, exploitation softness is high, and it is urgently to be resolved to become this field for the wood pulp cloth wet tissue of the performances composite demand such as thickness
The technical issues of.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of terylene wood pulp wet tissue and preparation method thereof.
The present invention adjusts wood pulp cloth terylene and finds with wood pulp proportion and terylene viscose glue can be replaced soft by adjusting production technology
Soft optimum formula, by adjusting the compound rear drying mode of wood pulp cloth, so that wood pulp cloth wet tissue thickness during post-production
Common wet tissue thickness on the market can be met or exceeded.
Technical scheme is as follows:
A kind of terylene wood pulp wet tissue, the raw material including following mass percent:
