SU1250803A1 - Laboratory unit for impregnating,drying and heat treatment of textile materials - Google Patents

Description

f

The invention relates to the technique of day and heat treatment of lengthy materials, such as textile materials, and can be used in rubber, tire and textile industry.

The purpose of the invention is to increase the profitability of laboratory research.

 The drawing shows a diagram of a laboratory installation for impregnation, drying and heat treatment of textile materials,

The laboratory unit for the impregnation, drying and heat treatment of textile materials contains a thermally insulated chamber 1 with heat fan equipment including a heater 2, a fan 3 and air ducts A, infrared emitters 5 can be installed inside the chamber 1. The installation also contains an impregnator 6, a hydraulic cylinder 7 for tensioning an endless belt of material; a device for pressing material, including a swing roller 8 and a hydraulic cylinder 9, a drive roller 10, a tension roller 1, and guide rollers 12-16. The endless ribbon of material is made up of two parts, one of which is longer than the distance between the guide rollers 12 and 13, made of heat-resistant material 17, for example T. Parfenova's glass fiber editor.

tissues, and the other - from the material under study 18. Sections of the endless belt 17 and 18 are connected at points A and B. In this case, all the rollers are taken out

5 outside the camera 1.

A laboratory unit for the impregnation, drying and heat treatment of textile materials operates as follows.

10 First, test material 18 is charged and attached to strip I7 and fiberglass fabric in chamber 1. Then the installation is switched to a mode for which heat 5 includes a ventilation system and infrared emitters 5 and sets the required tension with an endless belt hydraulic cylinder 7, and the pressing force - hydraulic cylinder 9.

20 After achieving a stable thermal condition in the chamber 1, the drive of the roller 10 is turned on, and the material under study is drawn through the chamber 1 with the required speed processing mode. After all the test material passes through chamber 1 and the glass cloth strip 17 enters it, the drive 10 is turned off, the sample of the material under study 18 is replaced and the processing mode is changed. At the same time, with each experiment, the material under study is saved in an amount equal to the length of the glass fabric section.
