Spinning, vacuumizing and mixing extruder of dacron waste cloth

Abstract

The invention discloses a spinning, vacuumizing and mixing extruder of dacron waste cloth. The spinning, vacuumizing and mixing extruder comprises an agglomeration machine, a reciprocating type mixing extruder and a single-screw-rod extruder in sequence along a line production direction, wherein the reciprocating type mixing extruder comprises an extruding and mixing system, a reciprocating driving system, an electric appliance control system and a temperature control system; the extruding and mixing system comprises a machine barrel which is arranged by sections, and a screw rod and a pin which are matched with each other and are arranged in the machine barrel; the machine barrel which is arranged by sections comprises an extruding section and a mixing section; the extruding section and / or the mixing section are / is provided with a vacuumizing hole; the vacuumizing hole is connected with vacuumizing equipment. By virtue of the equipment disclosed by the invention, the reciprocating type mixing extruder is innovatively used for mixing dacron materials before materials enter the single-screw-rod extruder, and steam and an oiling agent in the dacron materials, and auxiliary agents used in other spinning processes are pumped away, so that the degradation of the dacron is reduced, and the quality of regenerated dacron fiber yarns is improved.

Description

technical field [0001] The invention relates to a vacuum mixing extruder for spinning polyester waste cloth. Background technique [0002] As we all know, my country is a big country in the textile industry, and it is also a big country in textile consumption. Every year, my country's waste textiles are as high as tens of millions of tons. Polyester (PET) fabrics account for a considerable proportion of waste textiles. Therefore, how to recycle waste polyester fabrics through reasonable and effective methods has become an urgent problem to be solved. The existing polyester Almost all waste materials are buried and incinerated as garbage, causing damage to the environment, and the reuse rate is extremely low. In the existing polyester green treatment, the waste polyester fabric can be recycled and reprocessed to make it into recycled polyester fiber filaments. However, the existing polyester is often mixed and extruded directly through a single-screw extruder. Such mixing e...

Problems solved by technology

Polyester (PET) fabrics account for a considerable proportion of waste textiles. Therefore, how to recycle waste polyester fabrics through reasonable and effective methods has become an urgent problem to be solved. The existing polyester Almost all waste materials are buried and incinerated as garbage, causing damage to the environment, and the recycling rate is extremely low

In the existing polyester green treatment, the waste polyester fabric can be recycled and reprocessed to make it into recycled polyester fiber filaments. However, the existing polyester is often mixed and extruded directly through a single-screw extruder. Such mixing equipment and processes often lead to a large number of micropores in the polyester yarn in the later stage, which reduces the tensile strength of the polyester yarn and fails to meet the use requirements.
