A kind of ecological composite polypropylene non-woven fabric for agriculture and gardening and its production line

Abstract

The invention discloses an ecological composite polypropylene nonwoven fabric for agriculture and gardening and its production line. The upper surface of the forming template is provided with a forming groove and a living hinge A. The forming template is movably installed with a support rod through the living hinge A. The inner wall of the forming template is There are multiple air ports on the top, one side of the forming template is provided with an air port, and one end of the air port is provided with an air pipe, and the outer surface of the cover plate is fixedly installed with a hot pressing block and a living hinge B. After the spinning is completed, the forming The groove forms a complete non-woven fabric. Due to the limitation of the forming groove, the non-woven fabric can only be made into the shape of the forming groove. When the good non-woven fabric is blown onto the conveyor belt, the resulting non-woven fabric is in block shape and does not need to be wound and wound by a winding drum, which greatly reduces the working intensity and improves the processing efficiency at the same time.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric processing, in particular to an ecological composite polypropylene non-woven fabric for agriculture and gardening and a production line thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabric has moisture-proof, breathable, flexible, light weight, non-combustible, easy Decomposition, non-toxic and non-irritating, rich in color, low in price, recyclable, etc., for example, polypropylene (pp material) pellets are mostly used as raw materials, which are continuously melted at high temperature, sprayed, laid, and hot-pressed Produced in one step, polypropylene non-woven fabric is a new type of fabric product that does not require spinning and weaving. It has many advantages such as extensive sources, simple process flow, low cost, goo...

Problems solved by technology

[0002] Non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabric has moisture-proof, breathable, flexible, light weight, non-combustible, easy Decomposition, non-toxic and non-irritating, rich in color, low in price, recyclable, etc., for example, polypropylene (pp material) pellets are mostly used as raw materials, which are continuously melted at high temperature, sprayed, laid, and hot-pressed Produced in one step, polypropylene non-woven fabric is a new type of fabric product that does not require spinning and weaving. It has many advantages such as extensive sources, simple process flow, low cost, good mechanical properties, and relatively stable physical and chemical properties. It is widely used in the fields of clothing and textile industry, medical protective equipment, industrial matrix materials, etc., but because there are only regularly arranged methyl groups in its molecular structure, it lacks more functional groups and polar groups, making polypropylene non-woven fabrics There are defects such as poor aging resistance, poor hydrophilicity and dyeing ability, among which the poor hydrophilicity largely limits its application as a functional material in the fields of medical care, clothing, wiping materials, battery separators, etc.

[0003] The current high-temperature melting of polypropylene non-woven fabrics is to put the raw materials into the high-temperature cylinder and then melt them. There is a phenomenon that the melting is not complete, resulting in uneven melting of the overall mixture, and the residual volume of large particles inside it affects the processing process. Secondly, in the existing non-woven fabric production process, the produced non-woven fabric is rolled up, and the non-woven fabric in block shape cannot be produced, which has certain limitations, and the winding process is time-consuming , affect work efficiency, and the non-woven fabric made does not have flame retardant performance
