Description

FINISHING PROCESS FOR IMPARTING WATER-WASHABLE PROPERTIES TO SHRINKABLE TEXTILE BY WATER}

The present invention relates to a processing method for imparting washing dimensional stability to a fabric shrinking by water washing, and more particularly, the present invention provides a physical forced shrinkage and heat setting from the fabric manufacturing step to the fabric shrinking by water washing The present invention relates to a processing method in which a shrinkage phenomenon of a fabric caused by water washing is repeatedly suppressed to enable a shrinkage deformation within ± 3%.

In general, laundry is classified into a wet washing agent which removes water-soluble contaminants using a detergent and a water based surfactant and an organic solvent and dry washing (dry cleaning) which removes grease using an organic solvent.

Wet washing is an inexpensive washing method that can be easily performed at home, and is a washing method that is applied universally except for fabric materials which cause shrinkage deformation by water.

Fabric materials contracted by water washing include wool, silk, rayon, and the like, and along with the materials, fine fibers having elasticity in one or two directions depend on dry washing (dry cleaning).

Dry washing, however, does not wash clothes completely dry, but instead of water, a method of washing using a liquid compound called ethylene tetrachloride (C ₂ Cl ₄ ) or a mixture of hydrocarbons derived from crude oil, a "Stoddard solvent". to be.

Water used in wet washing is relatively inexpensive and can be easily discarded, but ethylene tetrachloride, a solvent used in wet washing, is more expensive than water, cannot be discarded unnecessarily, and may pollute the air or water. Therefore, the US Environmental Protection Agency (EPA) has taken a variety of measures to reduce the release of ethylene tetrachloride and prevent people from being exposed to ethylene tetrachloride.

In addition, as an alternative to dry washing (dry cleaning), a dry washing method using no ethylene tetrachloride has been developed, and petrochemical products which are less flammable than a stodard solvent are being developed. However, the solvent proposed by this method does not cause contamination, but it is expensive, which makes it difficult to use for washing.

Korean Patent No. 2001-7002320 discloses a laundry composition for reducing shrinkage of fabrics, more specifically a group consisting of all isomers of ethylene glycol, propanediol, butanediol, pentanediol and hexanediol and mixtures thereof. Fabric treatment compositions comprising a fabric shrink reduction composition (a) and liquid laundry / refresh composition (b) selected from are known.

In addition, Korean Patent No. 195-5563 treats a silk fabric with a water-soluble processing agent solution and crosslinks it to modify the product into a durable product having excellent fume and shrinkage properties, with almost no damage to tear strength, abrasion resistance, or touch, even when washed with water. Known methods for processing silk fabrics are known. The water-soluble processing agent solution is at least one of polyethylene-based softeners or amino-modified silicone softeners after adding a catalyst to the polycarboxylic acid compound having three or more carboxyl groups in one molecule at a ratio of 1: 0.5 to 1: 2.

An object of the present invention is to provide a processing method for imparting washing dimensional stability to a fabric shrinking by water washing.

It is another object of the present invention to provide a processing method for imparting washing dimensional stability to a fabric of rayon and nylon having poor dimensional stability of a fiber material.

In order to achieve the above object, the present invention is dipped into a resin composition for reducing fabric shrinkage in the fabric manufacturing step using the fiber material, for the fabric shrinking by water washing, and then dried and inclined by drying in a tension-free expansion tumbler And forcibly shrinking in the weft direction and thermally setting the contracted fabric, and repeating the immersion and heat setting steps, thereby providing a processing method for imparting washing dimensional stability to the fabric contracted by water washing.

More specifically, the processing method of the present invention

Pre-treated and dried fabric shrinking by water washing,

After immersing the dried fabric in the resin composition for reducing the fabric shrinkage, and then dry in the tension-free expansion bumbler forcibly shrink in the warp and weft direction,

Primary heat-setting the shrunken fabric in a wood cutter;

The heat-treated fabric is composed of a secondary immersion in a resin composition for reducing fabric shrinkage or water, and then secondary heat setting in a wood cutter.

In the above primary immersion, glyoxal resin 30-50 g / l, glyoxal catalyst 9-15 g / l, amino modified silicone 10-20 g / l, antistatic agent 5-10 g / l, acrylic resin 5 It is immersed in a resin shrink reduction resin composition consisting of ~ 10g / l and the residual amount of water, squeezed with a mangled pick-up rate of 50 to 60% and completely dried.

The secondary immersion is immersed in a resin composition for reducing fabric shrinkage or water consisting of 10-20 g / l of an amino-modified silicone, 5-10 g / l of an antistatic agent, 5-10 g / l of an acrylic resin, and remaining water, It is squeezed to 50-65% and dried completely.

As an example of the fabric shrinking by water washing, any one or two or more selected from the group consisting of rayon, nylon, silk, silk, wool, and hemp are woven and mixed.

More preferably, as the fiber material, a fabric of rayon and nylon manufactured by weaving warp yarns and rayon single yarns carburized with nylon and spandex at a ratio of 3 to 3.5 to 1 is used as a weft yarn.

Due to the processing method of the present invention, the wash shrinkage property of the fabric shrinking by water washing shrinks and deforms within ± 3%.

Hereinafter, the present invention will be described in detail.

The present invention provides a processing method for imparting washing dimensional stability to a fabric shrinking by water washing. That is, the fabric shrinking by water washing is immersed in the resin composition for reducing fabric shrinkage in the manufacturing step and then dried and then dried in a tension-free expansion tumbler to force shrinkage in the warp and weft direction, and open the shrinked fabric, but It is characterized by repeating the immersion and heat setting steps.

More specifically, the processing method of the present invention

1) pre-treat the fabric shrinking by water washing and then dry it,

2) the first immersion of the dried fabric in the resin composition for reducing the fabric shrinkage, and then dry in the tension-free expansion tumbler to force shrinkage in the warp and weft direction,

3) the heat-shrinkable fabric is first heat-fixed in a wood cutter;

4) After heat-treated fabric is immersed in the resin composition for reducing fabric shrinkage or water for the second time, the second heat setting in the wood braces.

The pretreatment of the step 1 is a degassing to remove the woolen (gassing) burning fine hairs on the surface of the dough surface, the acrylic resin impregnated on the slope to increase the weaving, and the antistatic agent to the fabric shrinking by water washing (脫 糊; desizing), the process of dyeing with reactive dyes, acid dyes, etc. according to the desired color.

In step 2, the primary immersion is 30-50 g / l glyoxal resin, 9-15 g / l glyoxal catalyst, 10-20 g / l amino modified silicone, 5-10 g / l antistatic agent, acrylic It is immersed in the resin composition for reducing fabric shrinkage, which is composed of 5-10 g / L of resin and the residual amount of water, and squeezed at 50-60% of pickup with mangles, followed by complete drying at 150 ° C. for 100-120 seconds.

The amount of the resin composition used for reducing the fabric shrinkage may vary depending on the number of yarns, the tissue constituting the form of the fabric, the weight according to the thickness of the fabric, the color of the fabric and the degree of softness.

The glyoxal resin performs a function of imparting fusiformity and shrinkage property, and it is preferable to use 30 to 50 g / l based on the total resin composition weight. If glyoxal resin is used at less than 30 g / l, the cellulose-based fabric is not wrinkled and shrinkage easily occurs after washing, and when used in excess of 50 g / l, shrinkage deformation after washing is The problem arises, although it is improved but it is not commodity as a fabric.

Glyoxal catalyst is a function that promotes the crosslinking reaction of glyoxal resin. The amount of glyoxal catalyst varies depending on glyoxal resin, and when using glyoxal resin 30g / l, 9-15g / L is preferably used. At this time, less than 9 g / l, crosslinking of glyoxal resin falls and lacks fugitiveness and shrinkage property, and if it exceeds 15 g / l, the handle of the fabric becomes worse and inferior in commerciality.

Amino-modified silicone is an essential component in the resin composition for reducing fabric shrinkage by the function of improving the softness of the woven fabric to improve the marketability, preferably 10 to 20 g / l. At this time, if the amount of use is less than 10g / l, the flexibility is insufficient, and if it is more than 20g / l, the surface of the fabric is slippery, poor commerciality.

The antistatic agent is used for the purpose of antistatic between fibers, and is not particularly limited, but the amount of the antistatic agent is preferably 5 to 10 g / L depending on the composition of each fabric material.

In addition, the acrylic resin serves to improve the excessively flaky handle, and in order to express the characteristics of the fabric material as much as possible, it is preferable to use 5 to 10 g / l of the total immersion liquid.

After the immersion, the resultant is squeezed at a pick-up rate of 50 to 60% with a mangle and then completely dried at 150 ° C. for 100 to 120 seconds. Thereafter, the dried fabric is dried in a tensionless expansion tumbler and forcedly contracted in a warp and weft direction.

The mangle is squeezed at a pick-up rate of 50 to 60%. If the pick-up rate is less than 50%, the amount of the composition resin to be processed on the fabric becomes low, so that the resin properties are difficult to be exhibited. It is not preferable to increase the cost and rough the handle.

At this time, forced shrinkage is dried in tension-free expansion tumbler maintained at 140 ° C for 5 minutes while passing through three cylinders having a surface temperature of 130 ° C. do. Various differences can be made depending on the material of the fabric, so the change of the fabric shrinkage before and after the stay must be accompanied in the tension-free expansion tumbler to achieve forced shrinkage.

The heat setting of the step 3 is to perform the fabric contracted in the step in the wood straightener, the wood straightener is to correct the shape of the fabric spread in the full width and length in the process of forced shrinkage.

The heat setting performed in the wood cutting machine is treated at 35 ° C for 45 seconds at 180 ° C with an inclined overfit of 18 to 23%. In this case, when overfitting in the inclined direction, ± 3% of the fabric by washing with water in the inclined direction It has the advantage of having shrinkage within washing, and if it is performed with less than 18% inclined direction, the shrinkage can be more than ± 3% by water washing, and if it is performed over 23%, Wrinkling of feces occurs.

In addition, since the material that requires washing dimensional stability in the fabric by suppressing the shrinkage of the fabric caused by temperature water washing is a cellulose-based, the heat setting temperature does not require a temperature of 180 ° C or higher, but only a yellowing phenomenon when the temperature exceeds 180 ° C. cause.

After the heat setting is completed, the present invention is characterized by imparting washing shrinkage within ± 3% to the fabric shrinking by washing by repeatedly performing the second dipping and the second heat setting.

At this time, the secondary immersion in step 4 is immersed in a resin composition for reducing fabric shrinkage or water consisting of amino modified silicone 10-20g / L, antistatic agent 5-10g / L, acrylic resin 5-10g / L and the remaining amount of water, After squeezing with mangled with a pick-up rate of 50-65%, it is completely dried at 150 ° C. for 100 to 120 seconds.

Since the composition of the resin composition for reducing fabric shrinkage used in the secondary immersion process is the same as described in the primary immersion process, it is omitted.

Also, the second heat setting degree is performed in the same manner as the first heat setting in step 3.

As the material of the fabric shrinking by water washing in the present invention, any one or two or more selected from the group consisting of rayon, nylon, silk, silk, wool and hemp are mixed and woven.

More preferably, as the fiber material, a cross-woven fabric of rayon and nylon manufactured by weaving warp yarn and rayon single yarn weaved with nylon and spandex at a ratio of 3 to 3.5 to 1 is used as a weft yarn.

Due to the processing method of the present invention, a fabric shrinking by water washing shrinks and deforms to within ± 3% of wash shrinkability.
