Characteristics of cold-proof felt in greenhouse:

In order to minimize heating costs and improve benefits, how to enhance the greenhouse heat preservation capacity and reduce heat loss has become the concern of many greenhouse users. The thermal insulation performance of solar greenhouse is a comprehensive result of many factors. The greenhouse insulation felt is laid on the front slope of the greenhouse. It is mainly used for night insulation of the greenhouse. Therefore, good insulation performance is the primary requirement for the insulation quilt. Secondly, the greenhouse thermal insulation is required to roll up after sunrise and put down before sunset, so the corresponding thermal insulation system is also a kind of movable coil system, so the thermal insulation material must be flexible material. Third, the solar greenhouse thermal insulation will always work in outdoor open-air conditions after installation. Therefore, it is required to be wind-proof, waterproof and aging-resistant to adapt to the daily natural climatic conditions such as wind, rain, snow and hail. * There should also be a wide range of sources of materials, low manufacturing and processing costs and market prices.

The felt is made of wool and processed and bonded (non-warp-weft interweaving). The main characteristics are as follows:

Elastic, can be used as shock proof, sealing, liner and elastic steel wire clothing felt material. Good adhesion, not easy to loose, can be punched into various shapes of parts. _The thermal insulation performance is good and can be used as thermal insulation material. Tight structure and small pore can be used as a good filter material. It has good wear resistance and can be used as polishing material. It is flexible, so it is bonded by shrinkage principle. After shrinkage bonding, the density and specifications can be used separately. Because of its compact density and stable performance, the felt can be stamped to produce various felt parts. The felt has good flexibility and can reach the specified length, which can be used for leather rolling belt and paper suction belt. The felt has good thermal insulation and can be made into a standard felt insole. The felt has moisture retention and elasticity and can be made into automobile door and window seals and central door and window seals. It does not use warp knitting, so it has good filtration performance and can be used to absorb oil. Most of the bottom of oil drums are made of felt to keep the ship clean. The machine parts packed with felt have high whiteness, good shock-proof performance, and can adjust the sound rate of musical instruments according to the size of felt.
