Embodiment Construction

[0019] In the figure: the straw 1 is the grass stem of the plant, and the straw 1 is piled on the top of the conveying mesh belt 2, and the conveying mesh belt 2 is connected with the grass inlet of the straw chopper 3, and the chopped straw 1 fiber is conveyed The net is transported to the primary fiber splitter 4, and then transported to the fine fiber splitter 6 through the fan 5 and the conveying pipe, and then the straw 1 fiber is sent to the air chamber 7 by the conveying pipe of the fan pipe, and the air chamber 7 is equipped with Airflow device: The fibers are in a uniform suspension state, so that the straw 1 fiber slowly settles on the polyester net 8, and the polyester net 8 is continuously pushed forward, and enters a pair of upper and lower pre-rollers 9 for pre-pressing. An infrared heater 10 is installed next to the pre-roller 9 for heating, so that the water in the fiber web is evaporated, and then heated and rolled by a pair of hot rollers 11, so that the fiber...

Abstract

The invention discloses a straw non-woven fabric and a production method of the straw non-woven fabric. Straws, a conveying mesh belt, a straw chopper, a primary fiber separator, a fan, a fine fiber separator, an air chamber, a polyester mesh, a pre-roller, an infrared heater, a hot roller and a non-woven fabric roll are adopted. The non-woven fabric is produced by effectively using the straws, the waste is changed into valuable, and the cost is low. The straw non-woven fabric manufactured by using the method has good use performance, soft handfeel and good water absorption, does not cause fiber drop, is particularly suitable for manufacturing industrial wiping cloth, is used for automobile heat insulation layers or building heat insulation layers and the like, and can also be used as moisture absorption cores in the middle of incontinence products such as paper diapers, sanitary towels and the like. A chemical processing method is not used for manufacturing the straw non-woven fabric, so the straw non-woven fabric has no secondary pollution, is totally biodegradable and is an environmentally-friendly product. The flow can be performed in fields, and the operation is simple, convenient and safe.

Description

technical field [0001] The invention relates to a nonwoven material, in particular to a straw nonwoven fabric and a production method thereof. Background technique [0002] Since my country's reform and opening up: agriculture has entered a new development opportunity, and agriculture has a bumper harvest every year. During the joyful harvest process, a large amount of rice, wheat, corn and other stalks will be produced. It is estimated that more than 600 million tons of straw will be produced in rural areas every year. For convenience, farmers generally use incineration to solve the problem of straw, which has brought serious environmental pollution, aggravated the greenhouse effect, and endangered human health. Therefore: straw burning has a great impact on people's normal life. After investigation, many technicians in the same industry continue to study the method of using straw without burning straw, which is in line with the direction of national industrial developme...
