Abstract

PURPOSE: A wrap knitted fabric is provided to have the excellent touch and the drape property by controlling the mixture of yarn material when the wrap knitted fabric is produced. CONSTITUTION: A wrap knitted fabric is produced by controlling the fineness of single fiber and the weight ratio of surface-texture-yarn and reverse side-texture yarn. The yarn of surface structure is a very fine fiber of polyester having the fineness of single fiber under 0.07denier, the yarn of rear structure is a thick fineness yarn of synthetic fiber having the 15-30deniers fineness of single fiber, and the weight ratio of the surface structure yarn and the rear structure yarn is 80-95wt%: 20-5wt%.

Description

Light hand paper with excellent touch.

The present invention relates to a warp knit excellent in touch.

As the fiber becomes thinner, the bending stiffness is lowered, so that the forge made of the ultrafine fiber has the advantage of having a very soft touch. In addition, the development of ultra-fine technology of synthetic fibers has been the motive for greatly improving the merchandise of clothing-sensitive materials.

In general, the production method of ultra-fine fibers can be classified into three types: direct spinning, two-component split spinning, and two-component eluted spinning. The fineness of the ultrafine fibers manufacturable by the direct spinning method is 0.3-0.5 denier, and the fineness of the ultrafine fibers manufacturable by the bicomponent split spinning method is 0.2 denier, whereas the fineness of the ultrafine fibers manufacturable by the bicomponent eluting spinning method is 0.05. Even denier levels can be produced. Commercialization using such ultra-fine fibers is progressing in various ways in the textile sector, but in the knitting sector, especially in the warp knitting sector, the commercialization is not progressed due to various defects generated during canon and post-processing.

Specifically, when the ultrafine fiber manufactured by the direct spinning method is applied to the warp knitted fabric, since the filaments are dispersed, the diameter is very poor, and the surface feel and the lighting effect of the manufactured warp knitted fabric are also poor.

On the other hand, when the ultra-fine fibers made by the two-component split composite spinning method composed of nylon / polyester are applied to warp knitted fabric, nylon and polyester are incompatible with nylon or polyester due to the tension or friction that is received during warp and weave due to their incompatibility. It is isolated and the warp and knitting is poor, the appearance of the warp knitted fabric is poor.

On the other hand, when the warp knitted fabric is manufactured using the ultra-fine fibers manufactured by the two-component elution spinning method, the warp and knitting properties are excellent and the appearance of the processed paper is good, but the one-component is eluted at the post-processing stage to become ultra-fine. There is a problem that the warp letter becomes too soft and the practical commerciality is insufficient.

The present invention is to provide a warp knit with excellent touch and drape property by appropriately adjusting the combination of the yarn material in the manufacture of warp knit in order to overcome the various problems described above.

The present invention seeks to provide a warp knitted paper having excellent processability such as diameter and size of the knitting and excellent touch, drape, lighting effect and appearance.

The present invention relates to a warp knit having a soft touch and excellent drape, lighting effect and appearance.

Specifically, the present invention is characterized in that when preparing the warp knitted using ultra-fine yarn, the single yarn fineness and weight ratio of the surface tissue yarn and the back tissue yarn are properly adjusted.

More specifically, in the present invention, the surface tissue yarn is a polyester ultra-fine yarn having a single yarn fineness of 0.07 denier or less, and the back surface yarn is a synthetic fiber Taeseodo yarn having a single yarn fineness of 15 to 30 denier, and the weight ratio of the surface tissue yarn: the back surface yarn is 80 to 95. % By weight: 20 to 5% by weight.

Hereinafter, the present invention will be described in detail.

First, the surface tissue yarn of the warp knitted fabric of the present invention is a polyester ultrafine yarn having a single yarn fineness of 0.07 denier or less. The polyester microfiber may be prepared by a method of dissolving the warp knitted fabric with a bicomponent eluting composite fiber having a polyester component and an alkali soluble copolyester of the sea component, and then eluting the sea component in a post-processing process. When the single yarn fineness of the surface tissue yarn exceeds 0.07 denier, the touch becomes hard and the lighting effect is lowered.

Next, the back surface yarn of the warp knitted fabric of the present invention is a synthetic fiber Taeseodo yarn having a single yarn fineness of 15 to 30 denier. It is more preferable that the impregnated fiber Taeseomyeonsa is monofilament because the weight of the warp knitted paper can be uniform, and specific examples thereof include polyester monofilament or polyamide monofilament.

If the single yarn fineness of the backside tissue yarn is less than 15 denier, the weight percent of the backside tissue yarn in the warp knitted fabric (processed paper) becomes too much, resulting in a good drape but no soft touch, and the single yarn fineness exceeding 30 denier. In such a case, fairness such as canon and chips is deteriorated.

The warp knitted fabric of the present invention has a weight ratio of surface tissue yarn: back tissue yarn of 80 to 95 wt%: 20 to 5 wt%. If the weight ratio of the back surface tissue yarn in the warp knitted fabric (based on the processed paper) is less than 5% by weight, the drape property is deteriorated, and when the weight ratio is more than 20% by weight, the soft touch is degraded.

The warp knitted fabric of the present invention uses a two-component eluting composite fiber, which is a polyester having an island component of 0.07 denier or less and a sea component of an alkali-soluble copolyester, as a yarn of surface texture, and has a single yarn fineness of 15 to 30 denier The amide monofilament can be prepared by knitting a warp knit using yarn as a backside tissue, followed by brushing, preliminary set, weight loss, dyeing, buffing and final setting under known conditions.

Since the warp knitted fabric of the present invention is a two-component eluting type of surface tissue yarn, it has excellent process passability such as diameter and cutting, and at the same time, the sea component is eluted at the time of post-processing, so that the surface tissue yarn becomes ultra-fine and has excellent lighting effect and soft touch. Can be expressed.

On the other hand, the warp knitted fabric of the present invention can solve the problem of excessively soft touch when manufacturing the warp knitted fabric with the conventional two-component eluting yarn because the back tissue yarn has an appropriate fineness and can express excellent drape.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited only to the following examples.

Example 1

The mono-filament of which 20 denier is used as a yarn of a back surface structure, and the light knitted paper of 23 densities / cm of density is manufactured. At this time, the weight ratio of surface tissue yarn: back tissue yarn in warp knitted fabric should be 85 wt%: 15 wt%.
