Problems solved by technology

This invention provides a technical route to solve the disadvantages of pure wood pulp paper filter rods, but the raw material is cellulose acetate tow for waste cigarettes, which has the problem of limited raw material sources and easy doping with impurities; and acetic acid The chemical properties of fibers are unstable, and deacetylation is easy to occur, which affects the smoking taste of cigarettes and the strength of paper; in addition, acetate fibers are obtained from wood pulp fibers, which still need to consume a large amount of wood fibers, which is not friendly to the environment, and higher price

Embodiment 1

[0028] Polyester fiber staple fibers with a specification of 2 denier and a length of 6 mm such as polyethylene terephthalate (PET) fibers are used, and the functional additive soybean polypeptide equivalent to 1% of the weight of polyester fibers is used. figure 1 As shown, polyethylene terephthalate fibers are added with functional additives for grinding to obtain polyester fiber pulp. Meanwhile, the non-wood pulp fiber straw pulp fiber slurry is prepared in addition or the finished product is directly purchased from the market. Mix the polyester fiber slurry and the straw fiber slurry in the ratio of polyester fiber slurry: straw fiber slurry = 30:70 in the mixing pool, and then use a paper machine to form and dehydrate , after drying once to obtain dry paper, the water-soluble chitosan solution of the coating material is coated on the paper surface according to 1% of the weight of the dry paper online, or the dry paper is rolled up and then coated offline on the paper surf...

Embodiment 2

[0030] Use polyester fibers with a specification of 0.6 denier such as poly(β-hydroxybutyrate) (β-PHB) fibers and pre-cut them to 8mm, add polyvinyl alcohol as a functional additive of 0.5% by weight of polyester fibers, and grind the paddles. Obtain polyester fiber slurry. Then, add prepared softwood pulp fiber, hardwood pulp fiber, according to the percentage ratio, softwood pulp fiber slurry: hardwood pulp fiber slurry: polyester fiber slurry=32:38:30 in the mixing tank Mix evenly with slurry. according to figure 1 As shown, use a paper machine to make a shape, dehydrate and dry once to obtain a dry paper, use a coating material macrostigmatrienone-polyethylene glycol aqueous solution of 0.1% by weight of the dry paper and apply it on the dry paper, and then After secondary drying, the quantitative value is 30g / m 2 , The finished paper filter material containing polyester fiber with a thickness of 0.1mm.

Embodiment 3

[0032]Adopt the polyester fiber that specification is 6 deniers and pre-cut to 3mm such as polyethylene terephthalate (PET) fiber, add the functional auxiliary agent soluble starch of 0.1% of polyester fiber weight, carry out paddle grinding, obtain poly Ester fiber size. Then, add prepared tobacco fiber slurry, coniferous wood pulp fiber, hardwood pulp fiber, according to percentage, tobacco fiber slurry: coniferous wood pulp fiber: hardwood pulp fiber slurry: polyester fiber slurry=10: 25:45:20 Mix the pulp evenly in the pulp mixing tank. Use a paper machine to make a shape, after dehydration and primary drying to obtain dry paper, apply the Zimbabwean tobacco extract solution on the dry paper according to 5% of the dry paper weight, and then dry it twice to obtain a weight of 150g / m 2 , A paper filter material containing polyester fiber with a thickness of 1.5mm.

Abstract

The invention provides a paper filter material containing polyester fibers for a cigarette filter tip and a preparation method thereof. The paper filter material comprises 10-90% of polyester fibers and the balance of wood pulp fibers or non-wood pulp fibers and also comprises a functional additive accounting for 0.1-5wt% of the polyester fibers and a coating material accounting for 0.1-5wt% of the paper filter material. The preparation method comprises the following steps: adding the functional additive into the polyester fibers, and jordaning to obtain a polyester fiber slurry; then respectively blending the polyester fiber slurry with the respectively prepared non-wood pulp fiber slurry or wood pulp fiber slurry in a blending tank; utilizing a paper making machine to make paper with pulp and shape, dehydrating and performing primary drying to obtain dry paper; coating the coating material accounting for 0.1-5wt% of the dry paper onto the surface of the paper; and performing secondary drying, thus obtaining the paper filter material provided by the invention. The paper filter material provided by the invention is rich in source, appropriate in price and environmentally-friendly. According to the invention, the range of available fiber raw materials for making the paper filter material is enlarged, the paper performance is improved, and the influence of the paper filter material on the smoking quality of cigarettes can be reduced.

Description

technical field [0001] The invention belongs to the technical field of auxiliary materials for cigarettes, and in particular relates to a filter material used for filling cigarette filter tips and a preparation method thereof. Background technique [0002] Cigarette filter is an integral part of cigarettes, and the filter material has a significant impact on the smoking quality and tar retention efficiency of cigarettes. Paper filter, as an effective coke reducing material, has received more and more attention from the tobacco industry. The traditional paper filter is usually made of special paper made of pure wood pulp fiber. The filter for cigarettes produced has disadvantages such as bad smell and easy collapse and deformation during the smoking process. [0003] Chinese patent application 200710098076.2 discloses a "manufacturing technology of cellulose acetate paper", which uses special paper (CAP) containing cellulose acetate as the paper filter material of cigarette...
