Benefits of technology

[0008] One objective of the invention is to provide tree bast fiber that features low price, wide applications, abundant source, and high economic benefits.
[0009] Another objective of the invention is to provide a method for processing tree bast fiber that features a feasible process route and a stable product quality.
[0012] The invention provides a textile fiber having a cheap price and wide applications for the textile industry. The fiber has similar performance to bast fiber, higher intensity than cotton fiber, good dyeing properties, and wide application prospect. It can be blended with other natural fibers, manual fibers and reproductive fibers to form fiber yarn for different purposes. This changes waste into a commodity, and brings about great economic and social benefits.

Problems solved by technology

As described in the patent, planting area of mulberries in China is very wide, but an objective of plating mulberries is to produce mulberry leaves for the sericulture industry instead of providing wood, therefore it is impossible for the market to provide a large amount of cheap mulberry barks for producing fiber.

example 1

[0028] In this example firtrees were used. Aged bark was manually removed from the surface of the trees. Tree bark was separated from trunks, paying attention so as to avoid introducing a hard lignified fiber layer within the trunk. Tree bark was immersed in a water pool comprising sulfuric acid at a concentration of 12 g / L, and 0.5% by weight of common laundry powder. The temperature was maintained at 60° C. for 12 hours. The obtained product was taken out and dried, and then put into a humidifying bin. Silicon oil-water emulsion was uniformly sprayed thereon, and it was covered and preserved with a canvas for 18 hours. The preserved tree bast fiber was placed into a tanning agent containing Lamepon A, JFC, peanut oil, engine oil and water for tanning. The tanned tree bast fiber was cut into pieces with a size of approximately 70 mm. The cut fiber was opened with a commonly-used fiber opener and then carded 3-5 times through a carding machine. The carded fiber was collected and put...

example 2

[0029] In this example ficus trees were used. Tree bark was manually separated from trunks. Tree bark was immersed in a water pool comprising sulfuric acid at a concentration of 3 g / L, and 1% by weight of common laundry powder. The temperature was maintained at 20° C. for 48 hours. The obtained product was taken out and dried, and then put into a humidifying bin. Silicon oil-water emulsion was uniformly sprayed thereon, and it was covered and preserved with a canvas for 24 hours. The preserved tree bast fiber was placed into a tanning agent containing Lamepon A, JFC, peanut oil, engine oil and water for tanning. The tanned tree bast fiber was cut into pieces with a size of approximately 70 mm. The cut fiber was opened with a commonly-used fiber opener and then carded 3-5 times through a carding machine. The carded fiber was collected and put into a dryer for drying. The tree bast fiber was finally separated into different dimensions using an air separator. The performance of the fib...

example 3

[0030] In this example nerium indicum mill were used. Tree bark was manually separated from trunks. Tree bark was immersed in a water pool comprising sulfuric acid at a concentration of 8 g / L, and 1% by weight of common laundry powder. The temperature was maintained at 50° C. for 24 hours. The obtained product was taken out and dried, and then put into a humidifying bin. Silicon oil-water emulsion was uniformly sprayed thereon, and it was covered and preserved with a canvas for 24 hours. The preserved tree bast fiber was placed into a tanning agent containing Lamepon A, JFC, peanut oil, engine oil and water for tanning. The tanned tree bast fiber was cut into pieces with a size of approximately 70 mm. The cut fiber was opened with a commonly-used fiber opener and then carded 3-5 times through a carding machine. The carded fiber was collected and put into a dryer for drying. The tree bast fiber was finally separated into different dimensions using an air separator. The performance of...

Abstract

Taught is tree bast fiber, along with a method for processing the same, the fiber being a natural textile fiber made of bark of trees except for mulberries and paper mulberries. The length of the fiber is 5 mm-65 mm. The fineness of the fiber is 0.3-2.5D. The intensity of the fiber is 0.275-0.582 N / tex. The breaking elongation rate of the fiber is 3%-7%. The method comprises the steps of peeling, sorting, degumming, skimming, drying, preserving, tanning, grinding, carding, baking, boxing and classifying, and packaging. The textile fiber is produced from a resource abundant in nature. The fiber has similar performance to bast fiber, higher intensity than cotton fiber, good dyeing properties, and wide application prospects. It can be blended with other natural fibers, man-made fibers and recycled fibers to form fiber yarn for various purposes. This method changes waste into a commodity, and brings about great economic and social benefits.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of International PCT Patent Application No. PCT / CN2006 / 000585 with an international filing date of Apr. 3, 2006, designating the United States, now pending, and claims priority benefits to Chinese Patent Application No. 200510034203.3 filed on Apr. 19, 2005. The contents of the aforementioned specifications are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a textile fiber, and more particularly to a tree bast fiber, as well as to a method for processing tree bast. [0004] 2. Description of the Related Art [0005] Wood is a natural resource of enormous significance to the survival and development of human beings. It has a wide range of application fields, and is close to people's daily lives. At present, most applications involve the utilization of tree lignin thereof, and tree bark is usually discarded in the process. How to ...
