Silk is the best textile material in the world. It is light and cool, moisture absorbing, moisturizing and heat resistant, has certain elasticity, feels full, full and smooth, and has a straight drape. However, all kinds of silk fabrics on the market dazzle everyone, and Golden Sun fabric experts teach you a few tricks to identify the good or bad of silk.
1. Fold: The fabric is pinched by hand and then released. The silk product has good elasticity and is basically free of creases, while the rayon fabric has obvious creases and it is difficult to quickly restore the original shape.
2. Touch: Silk feels like a handle, but chemical fiber does not have this feeling. Although rayon will feel smooth and soft, it is not crisp.
3. Pulling: Pull out a few yarns, wet a part with water and pull it off. If it is broken from the wet place, it is rayon fabric, and the broken head is a silky piece with different lengths.
4. Grab (grinding): Rubbing two layers of fabrics together will produce “silk†or “squeakyâ€, while other raw materials are not.
5. Combustion: Some parts of the yarn are burned, the silk can't see the open flame, the smell of burning hair, the black particles, can be crushed by hand, the silk is fired by the fire, the plastic smell, the fire is extinguished and the hard is left. Glue.
Check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Check valves have a poppet design for reliable, leak-free operation. they are in-line mounted. Ports are "/12" for SAE or G-pipe threads. This new series has a higher pressure rating. J3 corrosion protection is now included(240 hour salt spray test according to EN ISO 9227).
Features:
l Sizes 08 to 30
