Embroidery lace and its manufacturing method

) 및 이사 (

)에 모두 사용되며 유연성, 염색성 및 열 고정성이 우수한 자수 레이스에 관한 것이다.The present invention relates to an embroidery lace (embroidery lace) used in women's clothing, and the like, in particular modified polyester filament yarn bubble (base cloth), embroidery yarn (

) And director (

It is used for all) and relates to embroidery lace with excellent flexibility, dyeability and heat fixability.

Until now, embroidery lace has been embroidered with rayon, cotton yarn, etc. in light bubbles such as tulle, organdy, lawn, georgette, habutae, etc. It has been used in women's wear and the like as a high-quality lace fabric produced by practice.

Recently, with the development of synthetic fibers and processing techniques thereof, synthetic fibers have become widely used as bubbles and embroidery yarns in embroidery lace. For example, if the bubble is thin and the dimensions of the fabric are unstable, this drawback can be overcome by using a thin, high strength synthetic filament yarn such as nylon. On the other hand, in the case of a polyester filament yarn having a large rigidity, its rigidity can be reduced by alkali treatment in the form of a fabric which can be used well in the embroidery part or the bubble part, thereby giving flexibility to the product.

In this manner, when various fibers are used in combination, an embroidery lace made of various materials can be provided according to the purpose. Therefore, the use of embroidery lace is gradually expanding.

However, in the basic form of embroidered lace products, the bubbles, embroidery portions and moving parts must be identical in color. Moreover, as its use expands in recent years, heat stability has become an important factor for carrying out molding.

Embroidery laces, which use nylon yarn as the bubble and rayon or cotton yarn as the embroidery yarn, which are the most important products in the field of embroidery lace, must be dyed twice and have insufficient moldability due to difficulty in color mixing during dyeing. There are many problems.

It can be considered that these problems can be solved by using the same material for all parts. However, natural fibers are inferior in dimensional stability and formability, and nylon fibers are inferior in aptitude as clothing material such as discoloration resistance and have insufficient moldability. Thus, the above mentioned problems cannot be solved with such fibers.

Alternatively, the use of polyester fibers as the material forming all parts can also be considered. The rigidity of the polyester fibers can be reduced by caustic treatment with the above-mentioned alkalis, but their high temperature and high pressure are required for their dyeing, in particular high pressure treatment can significantly reduce the bulkiness of the embroidery portion, leading to a decrease in product value. There is concern.

In view of the above point of view, the same material is rarely used in all parts of the conventional embroidery lace, and the above-mentioned difficulties are still unavoidable at present.

It is an object of the present invention to solve the above mentioned problems by providing an embroidery lace which can be dyed in the same color without difficulty and exhibits excellent formability.

A subject matter of the present invention for carrying out the above-mentioned objects is a modified poly made by copolymerizing a dibasic acid component in which all of the bubbles, embroidery yarns and directors contain metal sulfonate residues with a polyethylene terephthalate component. Embroidery lace composed of ester filament yarn.

In preparing embroidery laces, a copolymer of a dibasic acid component containing a metal sulfonate moiety is copolymerized with a polyethylene terephthalate component to obtain a modified polyester filament yarn, which creates bubbles. Then, using the modified polyester filament yarn produced by the method described above to form the embroidery portion and the moving portion in the above-mentioned bubble, the embroidery product is treated with alkaline solution and sun bathed at atmospheric pressure.

Hereinafter, the present invention and its operation will be described in detail.

In the embroidery lace of the present invention, the bubble portion, the embroidery portion and the moving portion thereof are all formed of filament yarns composed of modified polyester fibers.

The modified polyester filament yarns used in the present invention are obtained by copolymerizing a dibasic acid component containing a metal sulfonate moiety with a polyethylene terephthalate component and are well known as cationic salt polyester polyester fibers. The modified polyester filament yarn may be a filament yarn prepared by copolymerizing a third component with the above-mentioned components, if necessary. The detailed manufacturing method is described in Japanese Patent Laid-Open No. 83-136, 826 and the like.

The modified polyester filament yarns used in the present invention contain metal sulfonate residues and can be dyed with cationic dyes at atmospheric pressure, which is indispensable for the present invention. In other words, this is a modified polyester filament yarn which, unlike conventional polyester fibers, does not require high temperature and high pressure in dyeing.

The tissue of the bubbles used in the embroidery lace of the present invention may be one of knit, woven and nonwoven fabrics. However, fabrics with plain weave are most preferred in view of ease of handling. As the filament yarn, one of arbitrary multifilament yarns and monofilament yarns may be used. Split fiber yarns and tape yarns may also be used.

Next, a method for producing the embroidery lace of the present invention will be described.

The modified polyester filament yarn used in the present invention is obtained by copolymerizing a dibasic acid component containing a metal sulfonate moiety with a polyethylene terephthalate component and melt spinning the copolymer. A method for producing such fibers is already described in Japanese Patent Laid-Open No. 83-136,826.

In the present invention, the bubble portion, the embroidery portion and the moving portion are all formed of the same material using filament yarn made of modified polyester fibers.

The embroidery style for bubbles may be the same as that used in conventional embroidery laces. After embroidering the bubbles, the modified polyester fibers are caustic treated with an aqueous alkali solution.

Caustic treatment is generally carried out under the following conditions.

Caustic treatment is carried out for the purpose of removing the rigidity of the polyester fibers and giving the fabric a beautiful surface gloss and flexibility. The weight loss by caustic treatment is controlled by the race according to the purpose and use. Typically, modified polyester fibers are easier to caustic than ordinary polyester fibers, so that the modified polyester fibers can have lower alkali concentrations and shorter treatment periods. The reduction rate by caustic treatment is preferably about 0% to 20%.

In the next step, the dyeing treatment is performed.

The modified polyester filament yarns used in the present invention contain metal sulfonate moieties as their fiber components and can be dyed with cationic dyes at atmospheric pressure. It can be dyed in a bath in boiling water under conventional dyeing conditions. The dye used for this purpose may be one of a cationic dye and a disperse dye.

Although it can be treated using an aqueous alkali solution after dyeing, it is not preferable because the dye dyeed by the dyeing process may be released.

In the present invention, the caustic treatment using the aqueous alkali solution and the dyeing treatment at normal pressure can be performed simultaneously. In this case, the dyes used are limited to disperse dyes. This simultaneous treatment can streamline the process and reduce the cost. Moreover, due to the alkaline bath used in the dyeing, the fabric can be flexibly treated during the dyeing, thereby preventing the loss of embroidery yarns and the like.

EXAMPLE

Next, the present invention will be described in more detail based on the following examples.

Example 1

The embroidered lace fabric thus obtained has the same color as bubbles, embroidery yarns and moving yarns, and is excellent in appearance.

Example 2

The embroidery lace fabric obtained in the same manner as in Example 1 was treated in a boiling bath containing 10 g / l sodium hydroxide for 30 minutes at a bath ratio of 1:30. As a result, the weight loss rate by caustic treatment was 10.7%.

Subsequently, dyeing is carried out using a cationic dispersion dye in the same manner as in Example 1.

The embroidered lace fabric obtained in this way has the same color of bubbles, embroidery yarns and yarns, and is excellent in appearance and rich in drape.

The lace fabric was steamed at 100 ° C. for 20 minutes to perform wrinkling, followed by washing. As a result, it showed excellent wrinkle retention. In the comparative test, a rayon embroidery yarn and nylon tulle were treated in the same manner as described above. In this case, the wrinkles disappeared after washing.

In comparative experiments, dyeing is performed with disperse dyes under conventional dyeing conditions.

Compared with the dyeings dyed under conventional conditions, the dyed fabrics of the present invention were more flexible in texture and more excellent in coloration between different parts.

The loss rate by dyeing in an alkaline bath was 5.2%.

In the embroidery lace of the present invention, the bubbles, embroidery yarns and yarns are all formed of commercial dyed modified polyester filament yarns. Therefore, it can be dyed by one bath at normal pressure. By carrying out the caustic treatment at the same time, it is possible to easily obtain an embroidery lace having excellent flexibility and color development and the same color of the bubble portion, the embroidery thread portion and the moving portion.

Furthermore, since the bubbles, embroidery yarns and yarns are all formed from the same modified polyester filament yarn, the heat fixability is very good. According to the present invention, the molding performance of the embroidery lace by wrinkle processing or the like which has been considered difficult to carry out so far can be significantly improved. Accordingly, the present invention exhibits excellent effects such as expanding the use of embroidery lace and the like.
