Problems solved by technology

Patent (CN101324012B) discloses the non-woven fabric that adopts jute fiber and low melting point chemical fiber or jute fiber and low melting point chemical fiber and cotton fiber, polyester fiber and viscose fiber to form one or more jointly, but it is by opening Loose mixing, needle punching, hot rolling and other processes; but compared with the wet manufacturing of non-woven fabrics, this process is too complicated, and it is easy to cause the breakage of hemp fibers in the opening step, thereby reducing the non-woven fabric. strength

Embodiment Construction

[0018] The present invention is described in further detail in conjunction with embodiment:

[0019] 1. Cut commercially available raw sisal fiber raw materials into sections about 1 to 10 cm in length, soak them in water for 10 hours, heat them for 3 times to form a mechanical pulp, then take 50 parts (by weight, the same below) of sisal fiber and 35 parts Bleached softwood kraft pulp fibers are mixed and put into a beater for beating to 30°SR.

[0020] 2. For ingredients, take 10 parts of polyvinyl alcohol fiber and 1 part of carboxymethyl cellulose to mix, fully decompose on the decomposer, and mix evenly;

[0021] 3. Put the mixed slurry on the wet-laid machine and form it on the net, the forming concentration is 0.03%, and dry it to get the finished product.

Abstract

The invention relates to a manufacture method of a sisal fiber wet nonwoven fabric. According to the manufacture method, the sisal fiber wet nonwoven fabric is mainly prepared from reproducible and naturally degradable sisal fibers and wood in the presence of a small amount of chemical fibers by a wet papermaking process. Mainly aiming at the disadvantages that the chemical fiber nonwoven fabric is difficult to degrade, the invention discloses a sisal fiber nonwoven fabric having the characteristics of simple formula, environmental friendliness and easiness in process operation.

Description

technical field [0001] The invention relates to a manufacturing method of sisal fiber wet-laid nonwoven fabric. Background technique [0002] Non-woven fabric is not actually "cloth", but a kind of plastic product. At present, the raw material composition of non-woven fabrics is mainly plastic, that is, 63% is polypropylene, 23% is polyester, 8% is viscose, 2% is acrylic fiber, 1.5% is polyamide, and the remaining 3% is other fibers. Not only are they non-degradable, but once they are used in large quantities, they will also cause huge consumption of non-renewable resources such as petroleum. Both their production and use will lead to the consumption of petroleum resources and environmental problems. [0003] There are currently two main methods of manufacturing non-woven fabrics, namely dry method and wet method. The dry method includes spunbond method, acupuncture method, melt blown method, etc. Wet-laid non-woven technology is a new technology that uses papermaking equi...
