Abstract
The invention is a mulberry skin fiber and the manufacturing method. The average length of the mulberry fiber is 31.50mm. The length C and V is 33.95 percent. The fracture strength is 5.30CN/dtex. The method comprises the processes of skin-removing, chemical boiling and refining, mechanical production, rinsing, acid cleaning, softness increasing, drying, combing, packaging and so on. The products of the invention are superior to or similar with the property of cotton fiber and have the luster of silk, but the cost is only half of that of the cotton fiber. The invention expands a new domain of natural fiber, adds new species of textile fiber, and initiates a new way of utilizing mulberry skin resources.
Description
The invention relates to mulberry fibre and preparation method thereof, more particularly about from paper mulberry bark, extracting textile fiber material-mulberry fibre and preparation method thereof.
Mulberry tree belongs to Moraceae, is deciduous tree, and its branch is made up of bast and cane two parts, and bast fiber content is up to 57.5%, and 1,200 ten thousand mu in mulberry is planted by China, and resource is extremely abundant, uses but generally only make fuel or vegetables hack lever at present.
Along with the progress of society, science and technology development, the shortage of natural resources force people to seek new resources, new varieties, and increasing people has recognized the importance of paper mulberry bark, use but generally all make paper making raw material at present.
One of purpose of the present invention provides a kind of mulberry fibre that supplies textile raw material to use.
Two of purpose of the present invention provides a kind of method of extracting mulberry fibre from paper mulberry bark.
These and other objects of the present invention will further be set forth and illustrate by following detailed description.
In the present invention, method of the present invention comprises to be removed that epidermis, chemical boiling-off, machinery are produced, rinsing, pickling, increases gentle, dry, combing, packaging and other steps, and the prepared mulberry fibre that goes out has following feature at least:
Average length 31.50mm
Length C, V 33.95%
The following fiber 7.95% of 16mm
Public of line density 2.86dtex(3500)
Fracture strength 5.30CN/dtex
Ultimate strength 15.15CN
Powerful C, V 10.35CN
Than resistance Ω 1.20 * 10
