JapanDraw texturing yarn (DTY) is a texturing yarn type of polyester chemical fiber. It uses polyester chips (PET) as raw material, and uses high-speed spinning polyester pre-oriented yarn (POY), and then draws it. False twist processing. It has the characteristics of short process, high efficiency, and good quality.
Polyester low-stretch yarn is an ideal raw material for knitting (weft knitting, warp knitting) or woven processing, suitable for making clothing fabrics (such as suits, shirts), bedding (such as quilts, bedspreads, mosquito nets) and decorative items (such as curtain cloth) , Sofa, wall cloth, car interior decoration cloth) etc. Among them, fine denier yarns (especially trilobal shaped yarns) are more suitable for silk-like fabrics, and medium-thick denier yarns can be used for wool-like fabrics.
Ranji’s research and injection theory and compounding techniques were discussed; the formulation of the pouring agent was drawn up and tested after the fiber was oiled, and it proved that its antistatic and smooth properties can meet the requirements. Most of the oils used in nylon high-elastic yarns and polyester low-elastic yarns still rely on imports, so the problem of localization of oil production is quite prominent.
It has the characteristics of high breaking strength and elastic modulus of general polyester, excellent heat setting, good resilience, heat resistance, light resistance, strong corrosion resistance, easy to wash and quick drying, etc., but also has high bulkiness, Good heat insulation, comfortable hand feeling, soft luster and so on.
Low-stretch yarn also has a sewing effect. Overlocking is also called overlocking, which is called overlocking in English. This process is required for all pieces of clothing. Since the main purpose of overlocking is to prevent the Textured sewing thread of the pieces from falling apart, the strength of the overhanging thread is not high. In order to save costs, the overburden thread is generally made of polyester network yarn, without twisting, and its strength is lower than that of sewing thread. It is different from ordinary sewing thread in that the overburden thread is made of polyester filament without twisting, while the sewing thread is made of polyester staple fiber with twisting.
