In recent years, textile and leather rollers, apron many new product forms, such as the structure of double skin rollers, inverted and artificial leather with a specific surface state of the apron, in order to adapt“Heavy pressure and high speed, high pressure“Spinning process demands, reduced deformation, improved stress crack resistance, high spinnability bonds. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.
The emergence of new technology in apron production meets the needs of automatic, continuous and efficient production efficiency. The patented technology introduced by Nippon Ozumang Industrial Enterprise Co., Ltd. is the jointless apron. It is made of a non-woven fabric impregnated with a polyaminase solution as an inner layer and an outer layer of rubber, and is formed by vulcanization and bonding.
The aprons introduced in French Patent (31) are made of synthetic glue or sheet material made of pinhole chemical fiber layers and cover layers. The coating can be PVC or polyurethane. Chemical fibers have a much thicker coating.
If the apron thickness is O. It is 5~1.3mm, the thickness of the chemical fiber layer is 0.4~1.2mm, and the thickness of the coating is 0.2mm. Cut the slices to length and glue them together.
In addition, according to reports (32), the British Ritson (Ritson) company replaced the traditional leather aprons with short fiber as the bottom of the polyurethane aprons, and the use of the aprons showed that it has a high sound sleep, ozone resistance and anti- The electrostatic property and the strength are slightly lower than that of synthetic rubber, but higher than that of Chinese leather. It is easy to connect and bond on my country's textile service machine, and the width of the bonding material is 2.10 mm. According to the situation, this apron is cheaper than cowhide apron.
