Embodiment Construction

[0008] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0009] see figure 1 , the concrete processing steps of the present invention are as follows:

[0010] 1. Raw material: The raw material is rice straw or wheat straw or corn stalk or other crop stalks.

[0011] 2. Cutting: Cut off the straw with a cutting machine.

[0012] 3. Cooking: Put the cut straw into a cooking container, add water to the water surface, and cook for 1-3 hours under the condition of 1-4 atmospheric pressure. Cooking can disinfect, sterilize, remove insects and remove other hybrid transmission chains.

[0013] 4. Dehydration: Dry and dehydrate the cooked straw to a moisture content of 10%-30%. Dehydration can be dehydrated in the sun or dried naturally, or sent to a dryer for dehydration.

[0014] 5. Extraction: After dehydration, the straw is sent to the fiber extraction machine for fiber extraction, and the dust removal equipm...

Abstract

The invention relates to a method for extracting the straw fiber, comprising: cutting the straws by cutting machine, boiling, dewatering, and extracting the straw fiber with diameter of 0.1mm~1.2mm and length of 2mm~5mm and the adhesive tissues thereof. The straw fibers produced by said method can be used for manufacturing products like mulching film and seedlings casting disc replacing plastic.

Description

1. Technical field [0001] The invention relates to a straw deep-processing product and a process method, in particular to a purely physical extraction method of straw fiber. 2. Background technology [0002] Chinese patent once disclosed a kind of " technology of extracting bamboo fiber by physical method " (application number: 01108748X, CN1406725A, open date: April 2nd, 2003), and its technological process is: former bamboo is cut off, rolling lamination, cooking Separation, fiber extraction, sieving and drying, and packing into storage. Chinese patent once disclosed " a kind of method for extracting banana stalk fiber " (application number: 031136435, CN1517456A, open date: on August 4th, 2004), and banana stalk is cut off with cutting machine, along its axis with breaking machine To break open, the stems are torn into flakes by hand, and the flake banana stems are extracted with a hand-pulled pineapple hemp scraping machine. But none of them are sui...
