Choose a sofa must see, what sofa fabric is good

Let's start with the testing standards
The testing standards for fabrics are very complex, including but not limited to the following

1. Physical indicators:

Yarn count, density, weight, breaking strength, tearing strength, anti-sliding, washing dimensional change rate, dry cleaning dimensional change rate, pilling, light fastness, light and sweat composite color fastness, hot color fastness , Color fastness to wet rubbing, flame retardancy, etc.

2. Chemical indicators:

Including formaldehyde content, PH value, presence or absence of odor, whether it contains prohibited dyes (decomposable aromatic amine carcinogenic dyes), whether it contains heavy metals, whether it contains fluorescence, whether it contains APEO\NPEO\PFOS and other prohibited surfactants, etc.

3. Performance:

Generally include feel, smoothness, bulkiness, softness, color difference level and so on.

4. appearance quality:

Specifications and sizes, defects, color difference, weft skew, etc.

Each of the above indicators will bring huge cost differences.
Wear resistance index, which determines how long the sofa can be used.

The cloth is made of fiber, which kind of fiber is wear-resistant: Of course it is polyester (polyester), nylon (nylon, nylon is the first synthetic fiber in the world. It is 10 times more wear-resistant than cotton and 20 times higher than wool. Times), acrylic fiber has better abrasion resistance than wool, so it is mostly used for synthetic wool fabrics.

Adding some man-made fibers to the blended fabric can greatly improve its abrasion resistance, so we often see polyester and nylon components in sofa fabrics

The next step is to look at the organizational structure. The tighter the organization, the greater the thickness, the more wear-resistant. Weight can reflect part of it, but not all of it.

For example, it is usually said that canvas is wear-resistant because canvas is much thicker than ordinary cloth. But compared with the same thickness, canvas is incomparable with polyester. Polyester cloth can exceed the wear resistance of cotton canvas as long as it is less than half the thickness of canvas.

The most wear-resistant natural fiber is wool and various rare animal hairs, and the most wear-resistant natural fiber is flax.
