The specific embodiment:

Technological process of the present invention is: cotton mill tube yarn-loose yarn-dye-weave, improvements have been to remove from the winding procedure of weft yarn between dyeing and weaving process, have the improved operation of part to relate to dyeing and weaving process.

Technological core of the present invention is in the soft stage of dyeing yarn to be carried out the liquid water-soluble Treating Cuttings with Paraffin Wax with bathing.In the winding process practice after in the past cancelling yarn dyeing, only, directly dyed yarn is carried out looming weaving with the winding procedure cancellation.In such cases, the tube yarn since after the centrifugal dehydration distortion greatly and oven dry back bobbin shape restorative poor, finally cause cone yarn forming bad, the coefficient of friction of yarn is very big in addition, cause when weaving yarn unwinding difficulty from the bobbin, it is serious that the loom latitude stops phenomenon, thereby fail to realize cancelling the purpose of winding procedure.The application of water soluble wax material among the present invention, can make the fiber surface of yarn cover one deck cere, be similar to the wax effect on raw cotton fiber surface, make yarn soft more and have certain elasticity, therefore, helping the shape of bobbin in drying course recovers, the cere of yam surface helps significantly reducing the skin-friction coefficient of yarn simultaneously, reduce that yarn rubs between yarn section and the bobbin surface in the unwinding process, the frictional force between yarn and the yarn guide member, finally simply and effectively address the above problem.

The soft operation of mistake after dyeing is to yarn water soluble wax mass treatment, guarantee that tube yarn oven dry back shape is good, improve the mantle friction performance of yarn simultaneously, the friction load when reducing High-Speed Yarn Unwinding in the follow-up weaving process between friction yarn section and the yarn surface, between yarn and the yarn guide member.

Wherein, the water soluble wax material, solid content is 35%-100%, finishes with bathing with the softener of conventional processes behind yarn dyeing, addition is 3-30g/L.

Wherein, the tube yarn is the product package form between loose charka, can be the paralleling tube yarn, also can be the taper socket yarn of tapering less than 4 degree.

Require at weaving process behind the cancellation winding procedure,, need install bobbin stabilizing ring 13 additional, use the auxiliary unwinding ring 11 of position of it's robbin means for correcting and internal layer yarn simultaneously for only being applicable to the holder creel of a yarn tapering greater than 5 degree; For the holder creel that the spool tapering is not required, need to use the position of it's robbin means for correcting and adjust the spool position, use the auxiliary unwinding ring 11 of internal layer yarn simultaneously.

Position of it's robbin stabilizing ring 12 needs to cooperate common winder cone 14, and bobbin stabilizing ring 13 inwall taperings are mated the tapering unanimity of the cone 14 of use, and its external diameter is than the little 0.5-2mm of parallel yarn dyeing bobbin 1 internal diameter.

In the present invention, bobbin stabilizing ring 13, position of it's robbin means for correcting and the auxiliary unwinding ring 8 of tube yarn internal layer are in conjunction with the bobbin matching component of concrete production practices development, have low, the practical characteristics of cost.In the technology of the present invention, the weft yarn package form of weaving process is consistent with product package form between loose charka, it is paralleling tube yarn or bobbin tapering tube yarn less than 4 degree, compare with the winder yarn that tapering is bigger, the less tube yarn of tapering has comparatively strict requirement to holder creel thread guide eyelet position, simultaneously for nonexpondable yarn dyeing tube, inevitable scared the and damaged situation in tube limit appears, so cause fracture during unwinding internal layer yarn very easily thus.But using the auxiliary unwinding ring 11 of bobbin stabilizing ring 13 of the present invention, position of it's robbin means for correcting and internal layer yarn can successfully address these problems.The bobbin stabilising arrangement is mainly used in and only is fit to the holder creel of tube yarn tapering greater than 5 degree, makes it need not change the holder creel and just can guarantee the spool fixed-site.The position of it's robbin means for correcting is mainly used in the center of proofreading and correct spool on the holder creel, the excessive tension fluctuation when reducing unwinding yarn.The auxiliary unwinding ring 11 of internal layer yarn makes internal layer yarn (in the 10～12mm thickness of bobbin surface) the yarn section of reducing friction significantly, effectively prevent from simultaneously to help the tail end of work bobbin and the head end of standby bobbin and smoothly transit owing to the damaged yarn breakage that causes in tube limit.

The position of it's robbin means for correcting mainly is made of the bobbin 1 and the correcting unit that have a same size with yarn dyeing tube, correcting unit can be that expansion link or laser pen 2 or other can play the object of positioning action, requires during operation expansion link elongation back over against thread guide eyelet 6 centers or with the center of the laser point directive thread guide eyelet 6 of laser pen 2.This device simulation tube yarn is placed on the state on the holder creel, utilizes expansion link or laser pen 2 light check bobbin 1 center line whether to be in thread guide eyelet 6 centers, proofreaies and correct to instruct.Referring to Fig. 2, wherein, connecting ring 5 is connected retainer ring 3 with bobbin 1, and retainer ring 3 matches with connecting ring 5 by screw thread, conveniently is that laser pen is changed battery, and built-in fixed screw 4 is fixed in laser pen 2 center of this device.

In the present invention, use tube yarn position correction apparatus, so that thread guide eyelet 6 is on the center line of straight tube yarn, last lower deviation is not more than 5mm, make cop be in the position that helps unwinding most, avoid a yarn position deviation to cause the yarn tension undue fluctuation too greatly and the broken end that causes.

The auxiliary unwinding ring 11 of internal layer yarn can be referring to Fig. 3, Fig. 4 in the Figure of description.Fig. 3 is auxiliary unwinding ring 11 profiles of internal layer yarn of the present invention.Wherein, unwinding circle 7 connects by being connected arc 8 curved surfaces with ring body 9.Fig. 4 is that the auxiliary unwinding ring 11 of internal layer yarn of the present invention cooperates figure with the work of spool 10.Wherein, auxiliary unwinding ring 11 ring bodies of internal layer yarn insert and are fixedly arranged in spool 10 yarn discharging ends, and unwinding circle 7 is higher than spool 10 surfaces.Wherein, the external diameter of unwinding circle 7 is than the big 12mm of external diameter of spool 101, thickness 3～6mm, the outer diameter of ring body 9 is slightly less than yarn dyeing bobbin 1 internal diameter 0.5-1mm, wall thickness 3～5mm, the radian that connects arc 8 is the 15-30 degree, arc length is 5-20mm, it connects arc 8 can well make this device be fixed on the yarn dyeing bobbin 1, does not need other fixtures.
