Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fabric having a special watermark pattern and a method for manufacturing the same.

Conventionally, watermark patterns have been produced by contact processing by using a fabric made of two or more types of fibers with different chemical properties and contacting only one of the fibers with a chemical. For example, there is a method of removing a mixed fabric of polyester fiber and cellulose fiber, a mixed fabric of polyester fiber and polyamide fiber, a mixed fabric of polyester fiber and wool, etc. using an agent that dissolves or decomposes one of them. Also.

A method has also been attempted in which a fabric made of a mixture of cationic dyeable polyester fibers and regular polyester fibers, which are the same polyester/l/fibers and have significantly different hydrolyzability, is treated with alkali and brought into contact with the cationic dyeable polyester fibers. However, all of these methods completely contact one fiber in the contact area, resulting in little change and poor aesthetics.

The design was lacking. Some attempts have been made to achieve incomplete contact, but these have had the disadvantage of unstable quality.

The present inventors have arrived at the present invention as a result of intensive research in order to provide a fabric with a special watermark pattern that is rich in aesthetics and design and is stable in quality. That is, 1 the present invention is a fabric including a special yarn feed having knots in which the core yarn is a corrosion-resistant polyester filament yarn), and the yarn feed is made of a polyester filament yarn with a polyester thread, in which the yarn is partially in contact with the polyester filament yarn with a polyester thread. There is also a watermark pattern part.

A fabric with a special watermark pattern characterized by the presence of knots of polyester μ fibers in the watermark part, and one or more corrosion-resistant polyester filament yarns (A
), one or more highly shrinkable and accessible polyester filament yarns CB) are placed in the heated area during false twisting.
II) After manufacturing a fabric using a special fed yarn having knots obtained by feeding at a feeding speed that satisfies the formula, contact processing is performed to form a watermark pattern and to add polyester polyester to the watermark pattern. This is a method for producing a fabric having a special watermark pattern characterized by leaving knots of fibers.

The present invention will be explained in more detail. The corrosion-resistant polyester filament yarn used in the present invention is a polyester filament yarn that is difficult to dissolve or become brittle due to chemicals or solvents. Examples include high quality polyester. In addition, copolymerized polyester (
Corrosion resistance can also be improved by treating with a chemical resistance improver such as an oil repellent agent or a water repellent agent.

tA, as polyester filament yarn, modified polyester μ obtained by blending polyalkylene glycols, an acid component capable of forming an ester containing an ionic group such as a metal salt sulfonate group during polymerization of polyester, and/or Examples include cationic dye-dyeable polyester fibers obtained by copolymerizing 1-67 glyco-components with all acid components constituting the polyester. Particularly preferred polyester filament threads include 1 to 5 mo/L'% of isophthalic acid containing metal salt sulfonate groups and 3 to 15 mole of isophthalic acid, adipic acid, sepacic acid, geltaric acid, etc. based on the total acid component. Polyester copolymerized with /I/, 1 to 5 mo) v- metal salt sulfonate group-containing isophthalic acid and 1 to 15 mo/
This is a cationic dye-dyeable polyester obtained by copolymerizing a polyhydric alcohol/alkylene oxide adduct (7111=μ number 1 to 10 mo/I/) of L/lIk. It is effective to add additives such as kaolin, silica, sodium alkylbenzenesulfonate, and sodium polystyrene sulfonate to the spinning polyester filament yarn in order to improve the spinning speed, and to increase the spinning speed. It is preferable that the difference in alkali solubility (30 f/1 caustic soda aqueous solution, bath ratio 1:100, treatment at 100° C. for 60 minutes) between the corrosion-resistant polyester filament yarn and the multi-cast polyester filament yarn is 5 times or more.

In addition, the erodible polyester filament yarn must have high shrinkage, usually 10% or more.

In particular, a dry heat shrinkage rate of 12- or more (JIS-L1073 (1)
965) B method) is preferred. The shrinkage rate of the corrosion-resistant polyester filament yarn is not particularly limited, and can be selected as appropriate depending on the desired effect, but it should be smaller than the normal polyester filament yarn, and the shrinkage difference is 5 inches or less, especially 1 to 3. % yarn is preferred.

In the present invention, the above-mentioned corrosion-resistant polyester filament A (A) and polyester filament yarn (B
) is used to manufacture a special yarn with knots, but yarn (
It is preferable to feed yarn CB) to the heating zone in the false twisting process of A) at a feeding rate that satisfies formula CI).

The reason for increasing the heat shrinkage rate of the supplied yarn (B) is to stably entangle the supplied yarn around the core yarn (A) by heat shrinkage. Due to the shrinkage difference between the feeding yarn (B) and the core yarn (A), the entanglement is stabilized by heat contraction, and the yarn simply wraps around the core yarn (A) and does not move in the longitudinal direction of the yarn, forming a stable node. become unable to do so. On the other hand, when the number exceeds 3, the intertwining becomes loose and it becomes difficult to leave stable joints by contact processing.

In the present invention, a fabric is produced by using such special yarns alone or with other filament yarns, such as regular polyester filament yarns, if desired.
The resulting fabric is contact processed to form a pattern. Contact processing can also be carried out by pre-treating areas other than the contact areas so that they are not touched, and then treating them with a contact liquid, but it is usually preferable to print a contact liquid thickened with a suitable adhesive on the contact areas.

After drying as desired, contact processing is preferably carried out by heat treatment. Next, remove the glue.

After neutralization and washing with water, it is finished. As a contact agent, an acid or an alkali is appropriately used, but an acid and an alkali can also be used together in a multistage treatment. The whole or a part of the fabric may be treated with an acid or an alkali before the contact treatment, or the whole fabric can be treated with an alkali after the contact treatment. In any case, in the present invention, it is important to leave at least a portion of the knots of the yarn feeder (B) in the contact area. In the method of the present invention, there is a large amount of yarn feeding (B) in the joints in the contact area compared to other parts, and the adhesion of the contact liquid is relatively small in the joints. Yarn feeding (
Even under the contact condition where B) is in complete contact, the yarn feeding at the knot (
Of course, it is easy to leave B) and it is bright.

According to the present invention, it is possible to provide a highly designed fabric in which knots remain in the watermark pattern. Also before contact and/or
Alternatively, by dyeing or printing after contact or during contact processing, the effect of different colors or shading of the core yarn (A), feeding yarn (A), and knots can be obtained, resulting in a fabric rich in aesthetics.

The present invention will be explained below with reference to Examples. In addition.

Parts and parts in the examples are based on weight.

Example 1 Polyethylene terephthalate filament (150d/48f) with a dry heat shrinkage rate of 12% was used as the core yarn, and a cationic dye-dyeable polyester filament with a dry heat shrinkage rate of 13.5% (5% based on the total acid component) was used as the core yarn.
