Description

Ring bobbin for elastic core-spun yarn steaming

Technical Field

The utility model relates to an elasticity covering yarn evaporates yarn and uses ring bobbin belongs to weaving equipment technical field.

Background

Along with the improvement of the living standard of people, the outdoor sports life style is rising, and the demand on elastic clothes is more and more. The spandex core-spun yarn is a raw material for weaving the elastic fabric, and can be dyed and woven only through yarn steaming and shaping due to larger elastic extension. In the prior art, the spun yarn tube for normal yarn steaming has the quality problems that due to the fact that no eyelet or elastic net exists, inner yarn and outer yarn close to the spun yarn tube are limited by the space of yarn steaming heat shrinkage, the setting effect is inconsistent, neps are increased after yarn steaming, the elongation rate is reduced, and the like.

The elastic core-spun yarn is produced through steaming spun bobbin yarn or cone yarn at 80-135 deg.c, vacuumizing for 20-35 min and winding into cone yarn. Particularly, the elastic core-spun yarn used as yarn-dyed fabric has the quality problems of uneven dyeing and reduced elastic elongation CV% due to poor yarn steaming uniformity. The patent publication No. CN2122159U discloses a breathable yarn steaming tube for the yarn steaming process of wool spinning industry, which comprises a top tube wall and a bottom tube wall, wherein the top tube wall and the bottom tube wall are provided with a porous tube wall and a non-porous solid, and the bobbin is in the shape of a winding bobbin. When the surface of the breathable yarn steaming pipe is wound with wool yarns, strip channels are formed between the adjacent axial ribs. The high-temperature steam can fully and effectively steam the inner layer wool yarn on the steam pipe through the high-temperature steam and the wall hole, so that the inner layer wool yarn and the outer layer wool yarn are uniformly steamed, and the quality of the wool yarn is improved. The patent is to steam the wool yarn, because the elastic yarn is wound tightly, the tube is used for steaming the spandex core-spun elastic yarn, and the problem of uneven elasticity of the inner and outer layer yarns can not be solved.

The invention discloses an elastic yarn and a processing method thereof through searching the invention patent publication number CN107675317A elastic yarn and the processing method thereof. The processing method comprises the steps of obtaining elastic yarns, and carrying out pretreatment, dyeing and post-treatment on the elastic yarns, wherein the pretreatment comprises the steps of obtaining the elastic yarns, namely carrying out first tube loosening on the elastic yarns, and carrying out pretreatment on the elastic yarns after the first tube loosening, namely carrying out treatment for 5-40 min at 80-125 ℃; performing secondary tube loosening and bullet eliminating treatment on the pretreated elastic yarn, wherein the tube loosening density of the secondary tube loosening is 0.2g/cm³～0.35g/cm³. The elastic yarn with uniform elasticity of the inner layer and the outer layer can be obtained by the processing method, the flow of the whole processing process is stable, and the quality of the elastic yarn is improved. The patent twines into a loose tube to steam the yarn, and the used loose tube bobbin cannot solve the problem of the inner layer of the yarn because of the normal eyelet yarn dyeing bobbinThe shrinkage has no elastic space, which causes the problem of uneven elasticity of the inner and outer layer yarns.

The main reasons of the technical difficulty are that the elastic core-spun yarn has high elasticity, the yarn density is 5% -10% higher than that of the normal cop, the yarn steaming shrinkage is high, the inner layer yarn is heated to shrink without an elastic space, and the elastic loss and the difference between the elasticity of the inner layer and the elasticity of the outer layer are high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the above-mentioned defect that exists when current elasticity covering yarn evaporates the yarn, provided an elasticity covering yarn evaporates yarn and uses ring bobbin, through set up a plurality of meshs in ring bobbin body middle section, realized that elasticity covering yarn obtains inside and outside elasticity unanimous after evaporating the yarn, ensured the quality of elasticity covering yarn.

The utility model discloses an adopt following technical scheme to realize:

a spun yarn tube for steaming elastic core-spun yarn comprises a spun yarn tube body;

the inner cavity is arranged inside the ring bobbin body and penetrates through the ring bobbin body;

a plurality of meshes are uniformly arranged on the middle section of the ring bobbin body, and the meshes are communicated with the inner cavity.

Preferably, the outside cover that the interlude of spun yarn tube body corresponds the mesh is equipped with the stainless steel net, the stainless steel net is elasticity stainless steel net. The elastic stainless steel net can well ensure that the inner side yarn has better elasticity as well as the outer layer yarn in the yarn steaming process, but is not attached to the outer wall of the ring bobbin body to influence the elasticity of the inner side yarn.

After the yarn is aerated with high-temperature steam, the yarn is shrunk by 1.6 to 2.8 percent, and the elasticity of the inner layer yarn is 0.1 to 0.5 percent less than that of the outer layer yarn. A layer of elastic stainless steel net is wrapped outside a ring bobbin body with meshes, and a space is reserved for thermal contraction of inner-layer yarns. After the stainless steel mesh is wrapped, the yarn winding part of the bobbin is reduced by 2-3 mm compared with the diameter of the traditional bobbin and is filled up by the stainless steel mesh, and the stainless steel mesh can be fixed by adopting a mode that the silicone high-temperature glue is firmly adhered outside the ring bobbin body or a mode of buckling with the ring bobbin body.

Preferably, the ring bobbin body is arranged in an inverted cone shape, and the inner cavity is consistent with the ring bobbin body in shape.

Preferably, the diameter of the meshes is 4-5mm, and the vertical spacing of the meshes is 10-15 mm.

The meshes of the elastic stainless steel net are 7-18 meshes. The elasticity and the air permeability of the stainless steel net are ensured.

The utility model has the advantages that:

the ring bobbin for steaming the elastic core-spun yarn is provided with the fine sand tube body, the fine sand tube body is provided with a plurality of groups of meshes, and the meshes solve the problem that the inner layer and the outer layer of the steamed yarn are unevenly heated;

elasticity covering yarn evaporate yarn and use ring bobbin, be provided with the stainless steel mesh on the outer ring bobbin body of mesh and adopt the inlayer to wrap there is elasticity stainless steel mesh measure, solved the great problem of inlayer elastic elongation loss for inside and outside yarn shrinkage factor is the same, makes to evaporate yarn back yarn elastic elongation and keep better.

Elasticity covering yarn evaporate yarn and use ring bobbin, saved and fallen into loose formula section of thick bamboo yarn and evaporated the yarn, fallen into tight formula section of thick bamboo yarn process again, once only fall into tight formula section of thick bamboo yarn, it is few with time, cost reduction.
