Abstract
The invention discloses a production process of novel chinlon spandex air-coated yarn. The production process comprises the steps of polyamide-6 granula feeding, melt spinning, side air blowing cooling, oiling and bundling and winding, yarn guide heating, cooling and false twisting, drafting and netting and winding forming are carried out on an elasticizing and air yarn covering all-in-one machine, and the production process is characterized in that after side air blowing cooling, a smoke exhaust system is added; drafting rollers are adopted in front of and behind a deformation heat box respectively in the yarn guide heating step of the elasticizing and air yarn covering all-in-one machine. The smoke exhaust system is added after side air blowing cooling, carbonized impurities guided out after resin heat melting can be effectively removed, and the quality of chinlon-6 fibers is improved. The two sets of drafting rollers are adopted in front of and behind the chinlon-6 raw silk deformation heat box of the elasticizing and air yarn covering all-in-one machine, fiber number control is more precise and evener, and quality is stable. Through the shape of a section of a spinneret hole of a spinning component, the fibers are provided with special-shaped sections, and therefore fabric manufactured through the special-shaped sections has the good hand feeling, air permeability and bulkiness.
Description
technical field:
The present invention relates to the field of polyurethane covered yarn, relate in particular to a kind of novel bright and beautiful ammonia air-coating silk and production technology thereof.
background technology:
Along with the continuous expansion of weaving face fabric kind demand, all kinds of special fibres, special processing process, the yarn of mannerism arises at the historic moment, and the empty bag silk of bright and beautiful ammonia is comparatively popular a kind of characteristic yarn on market in recent years.It is to take spandex thread as core, is composited with chinlon filament looping.Interweaving of spandex and polyamide fibre, not only can make fabric dye at normal temperatures and pressures, avoid the damage of High Temperature High Pressure to fabric, and it is ventilative to make knitted fabric have moisture absorption, soft, flexible and recovery, met people comfortable and easy to wear to clothes, the next to the skin and constant requirement of maintenance profile, is widely used in socks product, underwear, sweat shirt etc.
Common artificial fibre adopts circular cross section, but the fiber alignment of circular cross-section too closely causes gas permeability poor, moisture absorbing and sweat releasing weak effect, anti-perspective weak effect.Odd-shaped cross section is due to the variation of its shape, interfibrous frictional force is changed, simultaneously also variant to the sense of touch of human body skin, thus people or softness or smooth or fine and smooth feel given, and gas permeability and the bulkiness of odd-shaped cross section fabric also improve.
Publication number is that the patent of invention of CN101130910A discloses a kind of method of utilizing twisting Texturing Machines one-step method to manufacture bright and beautiful ammonia sky cladding plying, reached and only needed a machine can produce the silk of various kinds, thereby reduced the storage place of floor space and the high-elastic POLYAMIDE YARNS of machine, improved production efficiency and reduced cost.But it is unstable that the filament fiber number of POLYAMIDE YARNS prepared by this method is controlled, fiber quality needs further to improve.
