Abstract
The invention provides a kind of transfer type bobbin releasing method of stretch yarn, it is characterized in that adopting following steps: be on the bobbin or support of 150～300mm in external diameter 1) the stretch yarn metal; 2) stretch yarn on bobbin or the support being transferred to external diameter is on 30～75mm perforated pipe.Owing to transfer on the bobbin after the present invention changes the bread yarn into bread yarn process metal, not only can do the lower low bullet yarns such as nylon of elastic force, can also do the higher high-elastic yarns such as nylon bag spandex of elastic force, not only the elastic force loss is little, doing high-elastic yarn also can guarantee seldom hard waste amount to reduce cost significantly.This invention is an example with the nylon bag spandex, but the kind of producing is not limited to kinds such as nylon bag spandex.
Description
Technical field
The invention provides a kind of transfer type bobbin releasing method of stretch yarn, belong to technical field of textile printing.
Background technology
Stockinette is moderate because of its elasticity, act freely, make clothes show new vitality, catered to people's freedom, bold and unrestrained consumption concept, more and more liked by people, for the textile industry of 21 century provides completely new concept.At present, in order to guarantee guarantor's bullet of weft yarn in the yarn-dyed fabric, usually from following method is arranged:
1) with cotton with loose formula pipe winder: the direct network of stretch yarn is gone up dyeing to cotton with Song Shiguan, the temperature influence Yarn-recovery, because of the bobbin shielding, the collapsible space of internal layer is little, the elastic force damage is big, elastic force is inhomogeneous inside and outside the whole yarn.
2) bread yarn: the design internal diameter is the big bobbin of 2.5～3 times in cotton bobbin, and reforming equipment chuck and traverse behind the winder are extracted bobbin out, form the bread yarn; The bread dyeing yarn, the collapsible space of internal layer is enough, but yarn excessively bounces back, the easy adhesion of internal layer, and not only rewinding difficulty and internal layer yarn are unavailable, cause serious waste.
3) bourdon tube: reforming equipment chuck and traverse, directly doff is to bourdon tube, and because of the elastic reaction of pipe easily causes density irregularity, after the dyeing, shrink space is still very little, and the elastic force damage is big, and elastic force is inhomogeneous and the rewinding difficulty is big inside and outside the whole yarn.
4) disposable pipe: reforming equipment chuck and traverse, the doff poststaining, bobbin deformation fracture residue is difficult to be removed, and also damaged of elastic force.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned defective, can guarantee that stretch yarn dyeing back elastic force almost not have loss and the dyeing back tight tube hard waste amount transfer type bobbin releasing method than the stretch yarn of bread yarn minimizing 95%.Its technical scheme is:
A kind of transfer type bobbin releasing method of stretch yarn is characterized in that adopting following steps: be on the bobbin or support of 150～300mm in external diameter with the stretch yarn metal 1); 2) stretch yarn on bobbin or the support being transferred to external diameter is on 30～75mm perforated pipe.
Be the realization goal of the invention, the transfer type bobbin releasing method of described stretch yarn, in the step 1), the circular diameter made from the support outer is 150mm～300mm.
For realizing goal of the invention, the transfer type bobbin releasing method of described stretch yarn, step 2) in, perforated pipe adopts nonexpondable pipe, disposable pipe or bourdon tube.
Its operation principle is: is on the bobbin of 150～300mm or the support time with the stretch yarn metal in external diameter, and the elongation of stretch yarn elastic filament is 200～400%, transfer on the perforated pipe that external diameter is 30～75mm again after, the stretch yarn elongation can be reduced to former length substantially.So the stretch yarn of handling is under former elongation state, in dyeing course, and the elastic filament aging speed significantly reduces, and the elastic force loss of dyeing course does not have substantially, has guaranteed stretch yarn elastic force.
The present invention compared with prior art has following advantage:
1, in the metal of stretch yarn is handled, owing to stretch yarn elder generation metal on large diameter bobbin or support, is transferred on the minor diameter perforated pipe again, stretch yarn can be dyeed under approximate no tension force condition, elastic force is injury-free, and guarantees the Dry Sack rate height of lax dyeing;
2, internal layer has certain support, does not have hard waste, and cost significantly reduces;
3, technology is simple, the efficient height.
The specific embodiment
Embodiment 1: select 500Kg PA70D+LY20D for use, adopt the support that diameter makes for the 300mm stainless steel, the bourdon tube pipe that external diameter is 65mm.
Step 1) is on the support of 300mm in diameter with the PA70D+LY20D metal;
Step 2) after metal is finished, stretch yarn is transferred on the bourdon tube that external diameter is 65mm again.
After experiment showed, the stretch yarn dyeing of handling through said method, elastic force loss 0, the hard waste amount is 0.
Embodiment 2: select 200Kg PA40D+LY20D for use, adopt the cylinder that diameter makes for the 200mm resin, the resin bobbin that external diameter is 70mm.
Step 1) is on the cylinder of 200mm in diameter with the PA40D+LY20D metal;
Step 2) after metal is finished, stretch yarn is transferred on the bourdon tube that external diameter is 70mm again.
After experiment showed, the stretch yarn dyeing of handling through said method, elastic force loss 1%, the hard waste amount is 0.
Claims (3)
1, a kind of transfer type bobbin releasing method of stretch yarn is characterized in that adopting following steps: be on the bobbin or support of 150～300mm in external diameter with the stretch yarn metal 1); 2) stretch yarn on bobbin or the support being transferred to external diameter is on 30～75mm perforated pipe.
2, the transfer type bobbin releasing method of stretch yarn according to claim 1 is characterized in that: in the step 1), the circular diameter made from the support outer is 150mm～300mm.
3, the transfer type bobbin releasing method of stretch yarn according to claim 1 is characterized in that: step 2) in, perforated pipe adopts nonexpondable pipe, disposable pipe or bourdon tube.
