Abstract

A polyester fabric useful as a cleaning and having a volume feeling was manufactured by confounding a high shrinkage yarn and an ultrafine yarn as a weft yarn. An ultrafine polyester conjugated and the conjugated twisting yarn and a high shrinkage polyester yarn having unaqueous shrinkage rate of 20-40 % were confounded at air pressure of 2.0-2.5 kg/cm2 in the velosity of 1,300-1,500 m/min, thereafter weaved and treated with NaOH solution.

Description

Manufacturing method of polyester foam for cleaning

The present invention relates to a method for producing a polyester polyester for cleaning by improving the volume and cleaning performance by using a composite twisted yarn in which the high shrinkage yarn and the microfibers are air entangled.

Conventionally, forge is manufactured from a divided composite yarn composed of nylon and polyester, and the composite yarn is divided by physical or chemical methods to produce a cleaning cloth having a single yarn fineness of about 0.2 denier.

However, this cleaning forge has a limitation in improving the cleaning performance because of poor staining and the appearance of the product and the surface of the forge is smooth.

In order to solve the problem of dyeability, it is possible to prepare a paper by using a high shrinkable polyester or a composite yarn composed of nylon and a water-soluble ingredient, and dissolve and remove the water-soluble ingredient in a later process so that only one component of polyester or nylon is added to the final product. This existing forge has been proposed.

However, this product was able to improve the degradation of dyeing due to the two components, but the cleaning performance was not improved compared to the two-component forge.

In addition, we tried to improve the feel and cleaning performance by lowering the fineness of the used yarn. However, the lower the fineness, the lower the volume and shape stability of the final product.

The present invention solves the problems of the prior art, and it is an object of the present invention to improve the volume and shape stability of forge, and at the same time provide a method for producing a polyester polyester for cleaning having excellent cleaning performance.

The present invention is characterized in that weaving by using a composite twisted yarn made of air-entangled ultrafine polyester yarn and high shrink polyester yarn as a weft yarn and using a microfine polyester yarn as a warp yarn.

Hereinafter, the present invention will be described in detail.

The ultrafine polyester yarn used in the present invention has a final single yarn fineness of 0.3 denier or less and is composed of a fiber-forming polyester component and a usable component.

In addition, the high shrinkage polyester yarn of the present invention is that the non-shrinkage is 2 times or more than that of ordinary polyester yarn, that is, the non-shrinkage is 20 to 40%.

Since the high shrink polyester yarn shrinks more than the ultrafine polyester yarn in a later process, the microfine polyester yarn is blown out on the surface of the forge. These forged microfine polyester yarns improve the volume and cleaning performance of the forge of the present invention. In addition, since the high shrink polyester yarn is contracted to make the tissue dense, the shape stability of the forge is improved.

The weft yarn used in the present invention has an air pressure of 2.0 to 2.5 kg / cm ² and a yarn speed of 1300 to 1500 meters / minute when the microfiber polyester yarn and the high shrink polyester yarn are interlaced.

In the present invention, when the air pressure is less than 2.0kg / cm ² is not sufficient blending is made, if it exceeds 2.5kg / cm ² entangled (斑) is formed in the blended yarn is inferior in productability. In addition, when the yarn speed exceeds 1500 meters / min, the focusing properties of the ultrafine polyester yarn and the high shrink polyester yarn are significantly lowered, and when the yarn speed is less than 1300 meters / minute, there is a problem that the subsequent twisting process is not easy.

Example 1

A fiber composite polyester component having an intrinsic viscosity of 0.64 and a soluble polyester component obtained by copolymerizing 5% by weight of dimethyl sulfoisophthalic acid with respect to a computer component were composite spun to obtain an ultrafine composite yarn having 100 denier / 36 filaments.

On the other hand, 10 wt% of neopentyl glycol components were copolymerized to obtain a high shrinkage yarn of 30 denier / 12 filaments having a specific shrinkage ratio of 30%.

The ramp was subjected to arc treatment after twisting the ultrafine composite yarn at 300T / M of combustible water, a heat setting temperature of 170 ° C., and a winding speed of 64 meters / minute.

After weaving the micro-fine composite yarns at a heat setting temperature of 175 ° C and a firing speed of 300 meters / min, air-interlocking the high-yielding yarns with an air pressure of 2.5kg / cm ² and a firing speed of 1300 meters / min, and 300T / M Fired by.

Using the warp and weft yarn, weaving was done in a dobby tissue with a weaving density of 114 × 74 patterns / inch, and refined at 110 ° C. to shrink the high shrink yarn.

After heat-treating the woven fabric at 180 ° C., the microfiber yarn extruded on the surface was made fine by removing the usable component by reducing the process for 15 minutes at 100 ° C. in 7% caustic soda solution.

It was shown in Table 1 to dye the weight loss paper in a general manner and to evaluate the physical properties.

Example 2

When used, the weft yarn and weaving process is the same as in Example 1, but when the weft yarn is prepared, the ultra-fine polyester yarn was air-interlocked with a high shrinkage polyester yarn and air pressure 2.0kg / cm ² , yarn speed 1300 meters / min and twisted at 300T / M.

The woven fabric is weight loss processed and dyed in the same manner, and the physical properties thereof are shown in Table 1 below.

Example 3

When used, the weft yarn and weaving process is the same as in Example 1, but when the weft yarn is prepared, the ultra-fine polyester yarn was air-interlocked with a high shrinkage polyester yarn and air pressure of 2.5kg / cm ² , the yarn speed 1500m / min and twisted at 300T / M.

The woven fabric is weight loss processed and dyed in the same manner, and the physical properties thereof are shown in Table 1 below.

Comparative Example 1

As the ramp, the same microfine composite yarn as in Example 1 was used, and the weft yarn was twisted at 300T / M after twisting only the microfine composite yarn at a temperature of 175 ° C. and 300 m / min. Processed and stained and evaluated in physical properties are shown in Table 1.

Comparative Example 2

When used, the weft yarn and weaving process was prepared by weaving the same microfiber yarn as in Example 1 and air-interlocked with a high shrinkage polyester yarn and air pressure 3.0kg / cm ² , yarn speed 1300 meters / min and twisted at 300T / M.

The woven fabric is weight loss processed and dyed in the same manner, and the physical properties thereof are shown in Table 1 below.

However, the cleaning performance was evaluated by wiping the glasses with the fingerprints under the same conditions with the cleaning paper, and having the best cleaning power of ◎, excellent ones, ○, ordinary ones, and ≤ ordinary ones.
