Abstract
The invention discloses a high flame-retardant antistatic yarn and a processing method thereof, wherein the yarn comprises the following raw materials in parts by weight: 100-160 parts of polybutylene terephthalate/adipate, 1-3 parts of polyethylene glycol, 0.6-1 part of antistatic agent, 3-5 parts of flame retardant, 70-90 parts of wool fiber and 70-90 parts of cotton fiber; the processing method comprises the following steps: respectively carrying out vacuum drying on the poly (terephthalic acid)/butylene adipate and the polyethylene glycol, blending the poly (terephthalic acid)/butylene adipate and the polyethylene glycol with the antistatic agent and the flame retardant after drying treatment, carrying out melt spinning by a screw type spinning machine at the temperature of 250-290 ℃ and the spinning speed of 800-1200r/min, cooling, oiling, pre-drafting and winding to obtain polyester fiber; and secondly, performing flame retardant treatment on the wool fibers and the cotton fibers, twisting the wool fibers and the cotton fibers into a thread, and then performing a spinning process on the thread and the polyester fibers to obtain the high-flame-retardant antistatic yarn.
Description
Technical Field
The invention belongs to the technical field of spinning, and particularly relates to a high-flame-retardant antistatic yarn and a processing method thereof.
Background
The conventional textile fibers, especially the chemical fibers, are mostly combustible or inflammable materials and have high insulating property. In consideration of these two defects, both durability and comfort of the garment are considered to ensure the safety of workers involved in dangerous fields such as mining, fire fighting, and military industry. When people wear the clothes, people have a trouble that static electricity is easily generated, and the use of people is influenced.
The polyester fiber is difficult to bundle and wound on a machine part due to static electricity generated by friction during post processing; the finished product is easy to stain and absorb dust; when the shoe is worn, a human body has uncomfortable feeling due to electrostatic phenomenon, and particularly under a low relative humidity environment, the human body has electric shock feeling, stimulates nerves of the human body, generates adverse physiological reaction, and can cause skin inflammation and blood pH value increase locally; when electronic equipment is operated, static electricity generated by friction interferes with precise electronic equipment and electronic components, causes misoperation and component damage of the equipment and even whole circuit failure, and limits the application of polyester fiber in many fields.
Disclosure of Invention
In order to overcome the technical problems, the invention provides a high flame-retardant antistatic yarn and a processing method thereof.
The technical problems to be solved by the invention are as follows:
the chemical fiber not only belongs to combustible or inflammable materials, but also is difficult to bundle and wound on a machine part due to static electricity generated by friction during post processing; the finished product is easy to stain and absorb dust; the static electricity makes the human body feel uncomfortable when wearing the clothes.
The purpose of the invention can be realized by the following technical scheme:
the high-flame-retardant antistatic yarn comprises the following raw materials in parts by weight:
160 parts of polybutylene terephthalate/adipate, 1-3 parts of polyethylene glycol, 0.6-1 part of antistatic agent, 3-5 parts of flame retardant, 70-90 parts of wool fiber, 70-90 parts of cotton fiber and 200 parts of flame retardant treatment fluid;
