Why a Fabric Building is better?

from http://www.greatsheltercn.com

 Fabric building are an excellent alternative to conventional buildings for many reasons and have become a preferred solution in the building marketplace. 



Clear-Span Design

The absence of internal pillars or posts allows for maximum use of space. The high ceilings allow you ample clearance for moving or storing large equipment.

Naturally Bright for Lower Operating Costs

The translucent fabric cover plus the reflection from the white interior of the fabric increases the natural light within the building. This can reduce or eliminate the need for artificial lighting during daylight hours. A steel or wood building could cost thousands of dollars each year in additional lighting costs.

Easily Relocated

Fabric buildings are designed to be permanent, but can be quickly disassembled and relocated with minimal impact on the environment when compared to steel or wood structures.

Quick to Install

Fabric buildings typically require less lead and construction time than conventional construction, getting you up and running faster.

What is the nonwoven fabric component ?

Nonwovens  fabric, is directed or random fibers constitute a new generation of environmentally friendly materials , with moisture , breathable , flexible, lightweight , non-combustion , easily biodegradable, non-toxic non -irritating, colorful , inexpensive, can be recycling and so on. Such as multi-use polypropylene (pp material ) pellets as raw materials, high temperature melting, spinning , shop classes, hot coiling continuous one-step from production. Has the appearance and performance by some cloth called cloth .
. Spinning polypropylene thermally bonded together directly paved network , product strength is better than the average staple products , the strength of non-directional , vertical and horizontal strength similar. 8 , the environment, the majority of non-woven materials currently used is polypropylene, polyethylene and plastic raw materials , although the names of the two substances are similar, but are very different in chemical structure . The molecular structure of polyethylene having a very strong chemical stability , degradation is extremely difficult , so the decomposition of the plastic bag 300 years to complete ; the chemical structure of polypropylene is not solid, the molecular chains can easily be broken , which can effectively degrade , and the next step in the form of a non-toxic environment in circulation , a non-woven shopping bags in 90 days can be completely decomposed. And woven shopping bags can be reused more than 10 times the pollution of the environment after the waste is also only 10% of plastic bags
Non-woven fiber production is mainly polypropylene (PP), polyester (PET). In addition, polyamide (PA), viscose , acrylic , Polyethylene (HDPE), polyvinyl chloride (PVC). According to application requirements , woven into a one-time application-oriented and durable two categories.
Currently, non-woven rayon still dominate production , and by 2007 , this situation will not change much . Fiber used worldwide in the production of non-woven polypropylene , 63% , 23% polyester , 8% viscose, 2% acrylic fibers , polyamide 1.5% , and the remaining 3% for other fibers.
