Abstract
The invention relates to a manufacture method of a sisal fiber wet nonwoven fabric. According to the manufacture method, the sisal fiber wet nonwoven fabric is mainly prepared from reproducible and naturally degradable sisal fibers and wood in the presence of a small amount of chemical fibers by a wet papermaking process. Mainly aiming at the disadvantages that the chemical fiber nonwoven fabric is difficult to degrade, the invention discloses a sisal fiber nonwoven fabric having the characteristics of simple formula, environmental friendliness and easiness in process operation.
Description
Technical field
The present invention relates to a kind of manufacture method of sisal fiber wet nonwoven fabrics.
Background technology
Nonwoven fabric is not " cloth " in fact, but a kind of plastic products.The raw material of nonwoven fabric formation mainly is plastics at present, namely 63% is polypropylene, 23% is polyester, and 8% is viscose glue, and 2% is acrylic fiber, 1.5% is polyamide, remaining 3% is other fibers, and they not only can not be degraded, and in case a large amount of the use, also can cause huge consumption to non-renewable resources such as oil, its production and use all bring petroleum resource consumption and produce environmental problem.
The manufacture method of nonwoven fabric mainly contains two kinds at present, i.e. dry method and wet method, and dry method comprises spun-bond process, needle point method, meltblown etc.The wet nonwoven fabrics technology is a new technology utilizing paper making equipment and technology to produce non-woven cloth products.To place the fibrous raw material of aqueous medium to discongest into filament, different fibrous raw materials are mixed, make the fiber suspension slurry, the slurry that suspends be transported to lapper, and fiber becomes net to reinforce into cloth under hygrometric state again.Wet nonwoven fabrics is because adopted paper technology, so many countries include wet nonwoven fabrics in papermaking category, i.e. papermaking process in the world.
Present main study hotspot is to replace synthetic fiber for natural fabric.The intensity of bast-fibre is best in numerous natural fabrics, can satisfy to have high-intensity characteristics.
Sisal fiber is a kind of very good fibre resources, belongs to hard fibre, and fiber is long; Width is little, and near broad-leaved wood fiber, thereby length-width ratio is large.The former pulp brightness of sisal hemp is good, and pulling force is large, and is glossy, and elasticity is high, and elastic modelling quantity is large, rub resistance, anti-sunlight.Sisal hemp pulp not only has extra high tearability, but also has good air permeability, high bulk, high absorbent capacity, folding strength and wet strength.Its fiber interweaving ability is strong, and intensity is high.
Domestic existing technology mainly concentrates on research flax, hemp, bastose etc.The Qu Lijun of textile garment institute of University Of Qingdao had once attempted replacing polyethylene with flax, hemp, mix with wood pulp, carry out the shaping research of nonwoven fabric at six roller paper machines, the result shows, give birth to fiber crops after series of process is processed, mix with 50: 50 ratio with wood pulp, can form the nonwoven fabric that fiber is evenly distributed, but its method of processing hemp, flax is that it is cut off by soda boiling bleaching, carding process processing, this method still need be used a large amount of chemical reagent, cost is high, and the sewage disposal task is heavy.The Zheng Laijiu of Dalian Polytechnic College has then studied the technology that kenaf bast fiber slurrying and wet method prepare non-weaving cloth, draw by the quantitative measurement analysis to product: bastose should adopt pulping by cooking, bastose is short, intensity is large, proportion is little, moisture absorption and wet putting are strong, are used for the wet method non-weaving cloth and become net effective.Patent (CN101324012B) discloses one or more common nonwoven fabric that form that adopt in tossa and low melting point chemical fibre or tossa and low melting point chemical fibre and cotton fiber, polyster fibre and the viscose, but it is by techniques such as shredding mixing, acupuncture moulding, hot-roll formings; But make nonwoven fabric than wet method, this technique is too complicated, and easily causes the fracture of flax fibre in the shredding step, thereby has reduced the intensity of nonwoven fabric.Patent (200410054382.2) also discloses a kind of manufacture method of bast fiber nonwoven fabric, it is characterized in that adopting bloom fluffy, comb and parallel cotton fibers prior to spinning to become the steps such as net or air lay, acupuncture moulding, calendering moulding, wherein fibrous is comprised of the flax fibre of 50%-80% and the low-melting fiber of 50%-20%, perhaps fibrous by other of the flax fibre of 50%-70% and 50%-30%, perhaps formed by 100% flax fibre or 100% fire-retardant flax fibre.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of wet nonwoven fabrics take sisal fiber as raw material, adopt special PROCESS FOR TREATMENT to obtain the sisal fiber slurry, and mix an amount of wood pulp fibre and chemical fibre, adopt the wet method papermaking process to prepare the environmental protection type nonwoven cloth of excellent performance.
Technical solution of the present invention is to be made by following main materials and weight ratio:
More than the content percentage sum of each component equal 100%.
Its manufacture method is following steps:
A) commercially available living sisal fiber raw material is cut into the section that is about 1～10cm, Yu Shuizhong soaks the above after heat of 6h and wears into mechanical pulp, puts into the beater making beating to 15～40 ° of SR in proportion with after wood pulp fibre mixes;
B) batching, sisal fiber and the wood pulp fibre mixture that will possess certain beating degree by said ratio, together put into together with chemical fibre and dispersant and to discongest after device fully discongests and mix, adding water regulates between moulding concentration to 0.01%～0.5%, in the sheet forming apparatus online moulding of manufacturing paper with pulp, 105 ± 3 ℃ of oven dry of heating in vacuum namely get round shape nonwoven fabric.
Described wood pulp fibre is the composition of one or more materials in bleaching softwood kraft pulp, bleaching needlebush sulfite pulp, the groundwood pulp.
Described synthetic fiber are the composition of one or more materials of viscose, vinal, polyester fiber, polyamide fiber, and fibre length is 2～8mm.
Described dispersant can be a kind of in carboxymethyl cellulose, polyethylene glycol oxide, polyacrylamide, the guar gum.
Innovative point of the present invention is: prepare wet nonwoven fabrics take sisal fiber as raw material, sisal fiber intensity is high, good springiness, and the properties of product of preparing are good; Process sisal fiber with the method that thermomechanical is processed, technique is simple, pollutes and lacks, and production efficiency is high, strong adaptability, and the production process environment-protecting clean, product is easily degraded.
The specific embodiment
In conjunction with the embodiments the present invention is described in further details:
1. commercially available living sisal fiber raw material is cut into the section that is about 1～10cm, defibrator process became mechanical pulp 3 times after Yu Shuizhong soaked 10h, then put into the beater making beating to 30 ° of SR after getting 50 parts of (parts by weight, lower same) sisal fibers and 35 parts of bleaching softwood kraft pulp fibers mixing.
2. batching is got respectively 10 parts of vinals again, and 1 part of carboxymethyl cellulose mixes, and fully discongests on fluffer, mixes;
With the slurry that mixes in the wet-web former online moulding of manufacturing paper with pulp, moulding concentration 0.03%, oven dry gets product.
