Method for manufacturing mattress by using jute fiber

Abstract

The invention relates to a method for producing mattress by using tossa, which comprises following steps that 1, the tossa undergoes via complex enzyme degelatinizing process, while the complex enzyme degelatinizing process uses the complex enzyme water solution prepared from pectic enzyme and laccase to degelatinize tossa, which first adjusts the pH value of the complex enzyme water solution not lower than 4.0 but lower than 5.0, and increases temperature to 35-65DEG C and holds the temperature for 20-120min, then adjusts the pH value of the solution to 7.5-9.5, and holds the pH value under 40-70DEG C for 20-120min, and then inactivates the treated tossa, 2, the degelatinized tossa is mixed with chemical fiber, and the mixed fiber undergoes the processes of carding, mesh placement and needling, 3, the needled mixed fiber is thermally pressed and shaped. The inventive mattress is flexible and convenient, without bad feeling, while the mattress has better antibiosis and mite-proof functions.

Description

technical field [0001] The invention relates to a method for manufacturing a mattress, in particular to a method for manufacturing a mattress from jute fibers. Background technique [0002] At present, soft mattresses made of mixed fibers such as tussah silk, cotton, chemical fiber or kapok are soft and comfortable, and people usually use them directly under the sheets, but this kind of mattress is easy to deform, and has poor air permeability and hygroscopicity. , and the moisture is not easy to volatilize after absorbing moisture. After using it for a period of time, it is easy to make the user feel damp, which is not very comfortable, especially when using it in summer. High-quality mattresses are not easy to dry, which is not conducive to the health of children or patients. And the mattress made of tussah silk, cotton fiber, chemical fiber or kapok is easy to breed bacteria or other microorganisms, which is very unfavorable to people's health. Moreover, chemical fibers...

Problems solved by technology

But because the lignin content in jute is higher (up to 10-13%), several times higher than flax, makes jute fiber relatively thick, hard, not only makes the weaving of jute fiber, acupuncture performance poor, and contact with human body During use, people usually feel itching, not very comfortable, so it is necessary to remove the lignin impurities in jute as much as possible, and it is difficult to obtain ideal degumming and lignin removal by using common degumming methods. As a result, this greatly restricts the application of jute in daily necessities. At present, jute fiber can only be used to make sacks, hemp rope and other products with very low added value.

"Journal of Tianjin Polytechnic University" in August 2005, Volume 24, No. 4 "Enzyme Treatment Effects on the Properties of Jute Fiber" studied the effects of cellulase, hemicellulase, ligninase and pectin depolymerase on jute fiber. The impact of treatment, but the main research of this paper is to use the above-mentioned various enzymes to treat jute fiber separately, even if it is the compound enzyme treatment mentioned therein, it is only to use laccase and hemicellulase and cellulase respectively. Composite, Chinese patent document CN1232691C discloses a kind of method that application compound enzyme is carried out degumming to jute, and this method carries out degumming process to jute fiber with the compound enzyme of pectinase and laccase, but said method is degummed to jute fiber lignin impurity The removal is not ideal enough, and the removal rate is only about 76%, and the lignin content in the resulting jute fiber is still relatively high. When the products of this jute fiber are used to contact with human skin, people still have a tingling sensation, so it is not suitable for Manufacture of mattresses and other daily necessities that are in close contact with the human body
