According to the different information of the manufacturers, the products made by our fire-fighting ribbon manufacturers are different and have different characteristics. Climbing ropes are divided into main ropes and auxiliary ropes. The main rope is 60-100 meters long and about 10 mm in diameter, and the weight per meter is required to be 0. 08 kg or so, and the tensile strength is not less than 1,800 kg. In the past, jute was mostly made, but recently nylon fiber has been used as raw material. There is also a main rope with a diameter of 8-9 mm and a weight of 0 per meter. 06 kg, the tensile strength is not less than 1,600 kg, used to climb steep rock walls. The waist elastic band has good low-temperature flexibility and excellent stretch resilience, which can be kept consistent for a long time. Breathable elastic band, also called elastic thread and rubber thread, can be used as the bottom line of clothing accessories, especially suitable for underwear, pants, baby clothes, sweaters, sportswear, rhymes, wedding dresses, T- shirts, hats, busts, masks and other clothing products. According to the information, the fire ribbon manufacturer introduced the characteristics of the products to us.
Polyester:
1, strong wear resistance.
2. The water absorption is poor, and the official moisture returns to 0.4%(<20℃, relative humidity 65%, 100g polyester absorbent 0.4g).
3, simple problems affect static electricity, simple pilling.
4. Acid is not alkali. The manufacturers of fireproof webbing pay great attention to the damage of alkali concentration to the fabric surface at a certain temperature, which makes the fabric feel soft.
5, corrosion resistance and very good light resistance.
6. Polyester fiber fabric is not easy to wrinkle, has good dimensional structure stability, and is easy to use, clean and boring.
Polyester spinning of fireproof webbing;
1, FDY (filament): single fiber parallel lubrication, sub-bright, bright, semi-bright, extinction, brightness is getting weaker and weaker.
2. DTY (elastic yarn): monofilament winding, low spread, loose as shown in the figure.
Mesh (low elastic thread): there are various mesh points to increase the cluster capacity between fibers (mesh points have no mesh, light mesh, medium mesh and heavy mesh, which can be used for heavy mesh).
Under normal circumstances, it is necessary for manufacturers of fireproof webbing to adjust or distort the dimensions when using FDY and DTY, which can be used as warping.
Scale: add the strength of a silk; It is necessary for fibers to stay together. The fiber is externally lubricated and easy to weave.
Misrepresentation: increase strength; Increase the cohesion between fibers. Fireproof ribbon factory fabric has the function of wrinkling.
