Description
Technical field
The present invention relates to chemical fibre wrap yarn field, particularly relate to encasing system and the preparation technology thereof of the different pulled down yarn of a kind of polyamide fibre.
Background technology
Colour-spun yarns is first by stock-dye, the dyed yarn then spinned; Dyed yarn is by gray yarn through kiering, the dyed yarn that dyeing is obtained, and polyamide fibre is the Chinese title of synthetic fiber nylon, and translation title is again " nylon ", " nylon ", and formal name used at school is polyamide fibre, i.e. polyamide fiber.Terylene it be with p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) for raw material is through esterification or ester exchange and polycondensation reaction and obtained fiber-forming polymer---polyethylene terephthalate (PET), through the fiber that spinning and post processing are made.The yarn blackly to wash, washed raw material blending is in vain referred to as pearl yarn.
The different pulled down yarn of current polyamide fibre generally adopts covering machine/wrap yarn machine to weave, the spindle rotated by spool and drive spool carries out bag yarn, this structure is due to the Silk Road short (similar about 2m), woven polyamide fibre different pulled down yarn Tension Evenness is poor, high series yarn is required for COLOR FASTNESS, easily cause decorative pattern/type difference (depth lines is different), and graining (band bar).
Summary of the invention
Goal of the invention of the present invention is to overcome above-mentioned technical problem, provides one directly to utilize existing elasticizer structure, lengthens the Silk Road at about 5m, ensures encasing system and the preparation technology thereof of the different pulled down yarn of polyamide fibre of yarn COLOR FASTNESS.
In order to realize foregoing invention object, the technical solution used in the present invention is:
An encasing system for the different pulled down yarn of polyamide fibre, adopts polyamide fibre yarn and spun polyester thread to weave, comprises Jin Sha mechanism, preliminary treatment mechanism, bag yarn drafter and spooler along yarn direct of travel;
Described Jin Sha mechanism comprises the yarn spool-holder tube of feeding silk roller and two placement different size spun polyester threads, and the yarn on yarn spool-holder tube enters encasing system by feeding the drive of silk roller;
Described preliminary treatment mechanism comprises hot case and coldplate, and described hot case is deformation hot box, and for carrying out heating plasticizing to yarn, described coldplate is used for yarn coiled structure fixing after twisting;
Described bag yarn drafter comprises false twister, the second roller, Network device and the 3rd roller, by the second roller and hello silk roller, the second roller and the 3rd roller output drafting force, by false twister and Network device, bag yarn is carried out to polyamide fibre yarn and spun polyester thread, between described Network device and the 3rd roller, be also provided with auxiliary roller and lower hot case;
