A method for manufacturing a deodorant and antibacterial high-strength protective cloth includes: providing a first fiber thread and a second fiber thread, where the first fiber thread is a core-spun yarn formed by a blended slurry, a nano metal solution, a plurality of inorganic particles, and a plurality of thermoplastic polyurethane colloidal particles, the thermoplastic polyurethane colloidal particles are hot melted and then wrapped around a peripheral side of a core thread of the core-spun yarn for isolation from an outer wrapping layer of the core-spun yarn, and the second fiber thread is the same as the first fiber thread or is a single-thread yarn formed by the blended slurry and the nano metal solution; and intersecting and laminating the first fiber thread and the second fiber thread to form a plurality of bonding layers.

This application provides a fruit extract leather. The fruit extract leather includes a prepolymer material A, a prepolymer material B, and a base fabric. The prepolymer material A includes a fruit powder, and the fruit powder is obtained by grinding a remaining residue material obtained after fruit peels and/or fruit kernels are extracted. This application further provides a method for preparing the fruit extract leather. According to the fruit extract leather and the preparation method thereof provided in this application, polyester and other components in leather are substituted, fruit peels and/or fruit kernels are recycled, and waste and environmental pollution are reduced.

Reinforcing filaments or fibers, such as aromatic polyamide (aramid) fibers, can be reliably measured and consistently mixed into asphalt cement concrete by soaking the fibers in a wetting agent, then severing them to a desired length, and mixing the segments with other ACC ingredients. The wetting agent holds the fibers together loosely, so they can be distributed more uniformly throughout the ACC without clumping. The wetting agent soaks into the ACC mixture and/or evaporates, leaving the reinforcing fibers behind.

A liquid crystal polyester multifilament has an initial modulus variation of 3.0% or less and a tensile strength of 18 cN/dtex or more.

The present invention relates to a sealing head for machines for heat treating threads, comprising a frame fixed to a pressurized chamber through which a conveyor belt passes, a pair of horizontal rollers placed on top of each other and pressed against the opposite faces of the conveyor belt and of seals to form a sealed closure between the rollers and the frame, at least one of the horizontal rollers and the seals being connected to the corresponding movement actuators. Sealing head characterized in that the actuators of the horizontal roller or rollers and the seals between the rollers and the frame are in the form of pneumatic actuators without pistons, namely of the balloon or bellows type.
