The definition of the recycle polyester yarn




Polyester twisted yarn refers to the use of polyester cloth, waste polyester bottle chips, spinning waste silk, bubble material and pulp block as raw materials. The waste bottle chips are crushed and cleaned, and the mixture of various materials is dried, melt extruded, spun, wound, bunched, drawn and crimped (at the same time, different oil agents are added during crimping according to the needs of customers), relaxed and heat set, After cutting, polyester staple fibers of different lengths are formed.

Polyester twisted yarn 
The length is generally 32-102mm, and the size has many specifications of 1.5d-20d. It belongs to the full utilization of renewable resources. It has a broad market because of its low cost and good performance. There are many different varieties of polyester twisted yarn fiber, such as ordinary fiber, hollow fiber, triangular fiber, flame retardant fiber, etc. it is generally used in the filler industry of furniture and toys, bedding and clothing industry, Needle punched cotton industry, sewing and weaving industry.

The main test items of drying are moisture content, which is too high, poor spinning and easy hydrolysis.

Semi finished products are mainly used to detect the viscosity of oil-free wire.
The main test items of finished products include size (dtex), size unevenness, length (mm), length unevenness, breaking strength (CN / dtex), strength unevenness, elongation unevenness, specific resistance (Ω· sink cm), double length fiber content (mg / 100g), oil content, 180 ° C dry heat shrinkage, crimp number, crimp degree, crimp elasticity and crimp back
