2results about How to "Reduce or avoid losses" patented technology

The utility model relates to the technical field of detection cables, in particular to a packaging tube cable which comprises at least one tube cable body, a fireproof layer and a packaging layer, and the fireproof layer is arranged on the peripheral side of the at least one tube cable body; the packaging layer is arranged on the peripheral side of the fireproof layer, and the packaging pipe cable can still keep a normal working state within a certain time when encountering a fire burning condition, so that the time for taking emergency measures is reserved for workers, and the loss caused by fire is further reduced or avoided.

The application discloses an environment-friendly antibacterial blended yarn and a preparation method thereof. Raw materials of the blended yarn include natural plant fibers and modified modal fibers in a mass ratio of (65-70):(30-35); and the modified modal fibers are grafted with phenolic chitosan on surfaces. The natural plant fibers and the modified modal fibers are both green and environment-friendly fiber products. The natural plant fibers can provide part of antibacterial performance. The modified modal fibers have high dry and wet strength, and can compensate for the insufficient strength of the natural plant fibers. The obtained blended yarn has excellent strength and certain antibacterial property. Meanwhile, the modified modal fibers are grafted with phenolic chitosan on surfaces. The chitosan has excellent antibacterial performance, and the phenolic group can improve the poor cohesion between the natural plant fibers, so that the natural plant fibers and the modified modal fibers can be tightly combined together. The dry and wet strength and the antibacterial property of the obtained blended yarn are obviously improved.
