The basic principle of technical solution of the present invention foundation is: silk fiber is a kind of protein, form by accounting for 70% fibroin and 30% silk gum, the hydrophobic amino acid proportion is about 70% on the fibroin strand, hydrophilic amino acid is 30%, and the hydrophobic amino acid proportion is about 30% on the silk gum strand, hydrophilic amino acid is 70%, therefore, silk fiber has the ability of oil loving organic matter of absorption and hydroaropic substance, as the cigaratte filter core, can effectively hinder harmful components such as tar in the filter cigarette smoke and nicotine to a certain extent; The ratio of viscosities of low concentration sodium alginate soln is bigger, the Ca in the system
2+Ion on the one hand can make sodium alginate become calcium alginate to reduce its dissolubility and hygroscopicity, can between alginic acid and fibroin strand, form certain crosslinking effect on the other hand, help that fibroin is adsorbed by silk fiber and (mainly at fiber surface) forms and have certain flexible film in filter rod inside, improve the non-deformability of silk fiber, simultaneously, alginic acid (salt) also has certain bacteriostasis.
Compared with prior art, advantage of the present invention is:
1, the present invention adopted with human body and eco-friendly silk fiber be the primary raw material of cigaratte filter, with fibroin and alginate solution to the cocoon fibre cigarette filter tip processing of finalizing the design, therefore can avoid or reduce other chemical fibre material make and use in environment is polluted.
2, the silk of Huo Deing is the fibrous reticular structure that a kind of micron order fento forms, and specific area is big, helps adsorbing harmful substances such as the tar held back in the cigarette smoke and nicotine, to the not influence of taste of cigarette; And silk is a kind of long fibre, can avoid short fiber easily to be inhaled into the injury problem that human body (lung) is caused.
3, the source of silk is abundant, and is simple with its technology that is prepared into cigaratte filter, therefore, can obviously not increase product cost, easy to utilize.
