Embodiment 1

[0024] Choose weight percentage (dry weight, the same below) as 5% wood fiber, weight percentage is 10% acetate fiber, weight percentage is 80% polylactic acid fiber, weight percentage is 2% non-toxic organic silicon water repellent, There is also a non-toxic aluminum hydroxide flame retardant with a weight percentage of 3%, and solvents and auxiliary agents for papermaking are selected in addition. Such as figure 2 As shown, the above raw materials are added together to make a suspension-like pulp, and paper is made by conventional papermaking technology; after papermaking, 1g / m2 is coated on the paper surface 2 chitosan, dried; rolled into rolls..

[0025] According to the thickness specified in the national standard of cigarette filter rods, unwind the above-mentioned paper rolls at a certain speed in the filter rod forming machine, wrinkle them, spray an appropriate amount of triacetin plasticizer on the paper, and then roll them on the filter rods. Gather in a rod form...

Embodiment 2

[0028] Choose the grass fiber that is 25% by weight (dry weight, the same below), the polypropylene fiber that is 20% by weight, the polylactic acid fiber that is 50% by weight, the nontoxic polyvinyl alcohol hydrophobicity that is 1% by weight agent, as well as 4% by weight non-toxic dimethyl phosphate flame retardant, paper-making solvents, additives, derivatives of chitosan, etc. Such as figure 2 As shown, the above raw materials are added together to make a suspension-like pulp, which is made into paper using a suitable papermaking process and rolled into a paper roll.

[0029] According to the thickness stipulated in the enterprise standard for cigarette filter rods, the above paper rolls are unwound and wrinkled at a certain speed in a filter rod forming machine. The subsequent implementation process is the same as the subsequent process in Example 1.

Embodiment 3

[0031] Choose weight percentage (dry weight, the same below) as 45% cotton fiber, weight percentage is 40% acetate fiber, weight percentage is 5% polylactic acid fiber, weight percentage is 3% white activated carbon fiber, weight percentage is 2% % non-toxic polyvinyl alcohol water repellent, and 5% by weight non-toxic dimethyl methyl phosphate flame retardant, paper-making solvents, additives, chitosan derivatives, etc. Such as figure 2 As shown, the above-mentioned raw materials are added together to make a suspension-like pulp, which is made into paper by a suitable papermaking process and rolled into a paper roll.

[0032] According to the thickness of the filter rod agreed by the supplier and the buyer, the above-mentioned paper roll is unwound and wrinkled at a certain speed in the filter rod forming machine. Then spray an appropriate amount of triacetin plasticizer on the paper, and then gather it into a paper core 2 in a filter rod forming machine.

Abstract

The invention discloses a paper-core filter rod for cigarettes and a manufacturing method thereof. A paper core containing polylactic acid fibers, non-toxic flame retardants and non-toxic water repellents is taken as a filter material of the filter rod, and the paper core also can contain acetate fibers and wood fibers and the like. The paper-core filter rod is manufactured by using a method comprising the steps of adding various components into a paper pulp to carry out paper making firstly, manufacturing the obtained product into a paper core, and then manufacturing the paper core into a filter rod. The paper-core filter rod achieves an excellent degradation effect and a good filtering effect, and has a good flame retardant property, a good moisture-resistant property; and a new paper-core filter rod which is economic in cost and really has an industrialization prospect can be provided for users in the tobacco industry.

Description

technical field [0001] The invention relates to a filter material for cigarettes and a manufacturing method thereof, in particular to a paper core filter rod containing polylactic acid fibers, a non-toxic water repellent and a non-toxic flame retardant and a manufacturing method thereof. Background technique [0002] Cigarette filter rods are important materials in the tobacco industry. The initial cigarette filter rods use pure wood pulp paper as the filling filter material. Pure wood pulp paper filter rods have the advantages of good filtration performance and low price. However, their manufacturing The finished cigarette filter rod still has deficiencies in aspects such as flame retardancy, moisture resistance, and flavor absorption. Later, cigarette filter rods made of cellulose acetate were significantly improved in terms of elasticity, appearance, and taste, but the cost was relatively high. [0003] The paper core filter rod introduced in some patent documents refers...
