Abstract

PURPOSE: Provided is a process for producing a different shrinkage mixing yarn fabric which has excellent bulkiness, lubrication and draftiness improved by conjugated spinning polyester polymer by using conventional polyester polymer. Thereby, it is possible to improve lubrication, bulkiness, feeling, wearring property and it is possible to obtain the conjugated spinning polyester polymer by using the conventional polyester polymer. CONSTITUTION: The process comprises the steps of: combining a conjugated spinning high shrinkage polyester polymer with conventional polyester polymer; weaving warp and weft into plain weave. The different shrinkage mixing yarn is suitable 8-14% of shrinkage ratio(SR). If shrinkage ratio is more than 14%, different shrinkage effect is appeared excessively, so that lubrication is decreased. If shrinkage ratio is less than 8%, different shrinkage effect is deficient, so that bulkiness and drapability are decreased.

Description

Manufacturing method of biaxial blended yarn with excellent appearance and feel

The present invention relates to a method for producing a biaxial blended yarn fabric having excellent appearance and feel.

The conventional method for producing bi-shrink blended yarn fabric was to combine the high shrink yarn and the low shrink yarn manufactured by varying the stretching conditions. The residual shrinkage shrinks as the post-processing process, such as dyeing, progresses, and the shrinkage difference between the high shrinkage yarn and the low shrinkage yarn in the final processed product is narrowed, thereby insufficient the shrinkage effect. In addition, the interlacing and taslan method of air entanglement, which is adopted in the combination of high and low shrinkage yarns, has good process permeability in processes such as weaving preparation and weaving, and high shrinkage and low shrinkage. Although it has the advantage of preventing the separation of the yarn, the processing yarn is mixed with the entanglement and the non-lacing part, so many streaky phenomena occur due to salt and irregularities between the entanglement and the non-lacing part in the final processed product. There is a drawback that a clean surface cannot be obtained.

An object of the present invention is to use a di-shrink blended yarn prepared by complex spinning a modified polyester polymer having a high shrinkage property and a conventional polyester polymer as a light and weft yarn to give a rich volume, excellent drape, and soft touch. It is to provide a method for producing a yarn fabric.

The present invention is described in detail as follows. The bishrink blended yarn used in the present invention is produced by composite spinning by discharging a highly shrinkable modified polyester polymer and a conventional polyester polymer so that the shrinking effect is excellently expressed on the fabric surface. The yarn is woven into plain weave using light and weft yarns. The biaxial blended fiber may have a shrinkage ratio (SR) of 8 to 14%. If it exceeds 14%, the shrinkage effect is excessively expressed, so the smoothness is not preferable, and if it is less than 8%, the shrinkage effect is not sufficiently exhibited after processing, thereby significantly reducing the bulkiness and drape.

Shrinkage rate (SR) is defined by the following equation.

L ₀ -L ₁

Shrinkage (%) = ━━━━━━━ × 100

L ₀

(Wherein L ₀ is the length of the sample measured under a load of 0.1 g / d, L ₁ is the length of the sample after treatment for 15 minutes in 100 ℃ dry heat to a constant length and then shrinks again for 15 minutes in the tension state in 100 ℃ hot water) Measured in the same way as L ₀ )

At this time, when using the entanglement treatment in the stretching process to improve the workability in the weaving preparation or weaving process, because the streaks occur due to the entanglement after processing, the surface of the fabric is not clean, so the present invention is used as it is without tangling treatment It was. As a result, a uniform and smooth fabric was obtained.

When weaving fabrics made of a composite yarn of a high shrinkage modified polyester polymer and a conventional polyester polymer as a light and weft yarn, the weft density acts as an important factor that effectively shows the shrinkage effectively. 160-200 bones / inch is suitable, and weft density should be 90-110 bones / inch. If the inclination density is less than 160 bones / inch, the elasticity of the fabric is reduced and slippage occurs. If the warp density exceeds 200 bones / inch, the surface smoothness is reduced.

In addition, when the weft density is less than 90 bones / inch, excessive shrinkage in the inclined direction in the processing process causes the fabric to lose smoothness and drape and slip. In addition, if it exceeds 110 bones / inch, excessive shrinkage occurs in the weft direction in the processing process, and a weak stripe (streaky phenomenon) is formed in the warp direction in the fabric, and the warp weight: the weft weight ratio of the weft weight ratio exceeds 1, Productivity decreases and manufacturing costs rise.

Example

Using a modified polyester polymer having a heat shrinkage of 70% and a conventional polyester polymer (5% heat shrinkage), the composite was spun to have a fineness of 75 deniers. At this time, the discharge hole of the modified polyester polymer having high shrinkage characteristics was 12 holes, and the discharge hole of the conventional polyester polymer was 60 holes. The percent shrinkage (%) of the yarn was 14% and there was no air entanglement in the stretching process. The yarn was used as a warp yarn, but the warp density was 185 pieces / inch, and the weft was woven into plain weave with a density of 90 pieces / inch. This is a conventional post-processing method, which has undergone refinement, presetting, weight loss, dyeing, resin processing, etc., resulting in excellent bulkiness, smooth surface, no streaky phenomenon, and excellent elasticity and drape. there was.
