Description

Water-repellent dresspants}

The present invention relates to a water-repellent dress pants, and more particularly to a water-repellent dress pants to apply the water-repellent fabric so that the liquid, such as coffee, water, rain, snow and the like flows down.

General dress pants were made of suit pants applied to a fibrous fabric, such as polyurethane, acrylic, wool.

However, they are easily absorbed by these fibrous fabrics. Therefore, pants using these fabrics are easily wetted when it rains.

And, it is common to form the dress pants at the height of the shoe heel. If there is moisture on the bottom, the moisture is absorbed along the end of the pants, and the end of the pants is wet, causing bad fit.

In order to solve the above disadvantages of the prior art, it is carried out by high durability processing by the fluorine-based water and oil repellent agent in the fabric to suppress the absorption of moisture.

However, it is difficult to apply to the dressing pants that need to maintain the quality of gum (gum) is easily generated.

As described above, the water-repellent suit pants according to the prior art may have a problem in that the gum may be induced during the current water-repellent treatment process, and may not be applied to the part that can maintain the suit pants and the quality.

The present invention is to solve the problems of the prior art, the purpose of using a water- and oil-repellent agent-treated fabric to the pants or skirt to be well ventilated without moisture is absorbed.

1 is a schematic diagram of forming a water-repellent dress pants in the processing step using a crosslinking agent according to the present invention.

Water-repellent formal pants according to the present invention to achieve the above object,

It is characterized by using a fluorine-based water- and oil-repellent agent consisting of three components such as a functional group, a tactile regulator and a reactor to process the fabric fibers and to use them as a cloth for pants.

The present invention is described in detail as follows.

Structural formula 1 is a structural formula of the fluorine-based water and oil repellent agent treated on the fabric of the present invention.

Structural Formula 1.

The structural formula 1 is a general structural formula of a fluorine-based water and oil repellent, and is a kind of acrylic resin called an alkyl acrylate copolymer.

The resin consists of three components, such as a functional group, a tactile regulator, and a reactor.

Here, the functional group is a fluorine group, i.e., a fluoroalkyl group component, and contributes to the water / oil repellent performance, and the tactile regulator is usually an alkyl group component and the touch changes with the length of the chain. At this time, the longer the chain, the softer the touch.

In addition, the reactor is a part that plays an important role in the durability of performance, and is the most important factor in the development of high durability water and oil repellent processing technology. At this time, the durability is to improve the adhesion between the fiber and the water repellent and to prevent the separation and dropping even by the strong exercise effect by washing or dry cleaning. Here, the adhesion between the fibers, the fabric and the water repellent, is largely divided into the intermolecular van der Waals forces and covalent bonds.

The processing step using the fluorine-based water and oil repellent agent of the above formula 1 is carried out by the following method.

First, as an intermolecular force processing process, the force acting between two molecules when an object gets closer from the molecular set is called intermolecular force.

In general, the fluorine-based water and oil repellent agent is hydrophobic, and has strong adhesion, that is, intermolecular force, with a hydrophobic material such as polyester, while the adhesion, that is, intermolecular force, is weak with hydrophilic material such as cotton, and thus durability is reduced when washing.

The second method is an under coating method. In the case where the properties of the fabric fibers and the water-repellent agent are different as described above, both the materials are formed by forming a processing agent familiar with both materials between the fabric fibers and the water-repellent agent as a neutral agent of the third component. It is to indirectly improve the adhesion between materials. In this case, as the coating agent used in the undercoating method, melamine resin is most used.

A water and water repellent treatment as described above enables the durable water and oil repellent processing for a wide range of fibers.

However, the durable water- and oil-repellent processing of cellulose fibers such as cotton and rayon has a disadvantage in that the adhesive force is degraded due to a severe difference in properties between the water repellent and the fabric fiber.

Third, a method of using a crosslinking agent to solve the disadvantages of the above-described methods, to combine the functional groups of the general fabric fibers and functional groups of the water and oil repellent agent by chemical reaction with the crosslinking agent.

For reference, cellulose fibers are rich in functional groups called -OH groups.

By processing the fabric fibers with fluorine-based water and oil repellent agent as described above, to make suit pants to prevent the damage to the elegance of suit pants due to liquid, such as water, liquor, coffee, juice, rain, snow, etc. that exist around the living To improve the dignity as well.

Hereinafter, with reference to the accompanying Figure 1 will be described an embodiment of the water and oil repellent treatment method using a chemical method using a crosslinking agent of the third method as follows.

First, a sample is made of 100% cotton twill and T / C, a twill fabric containing polyether / cotton at a ratio of 65 and 35%.

Then, the sample is immersed once in a solution containing a fluorine-based water and oil repellent agent, MF, SU-125F, BP-11, melamine resin, catalyst, penetrant and acid, and then squeezed once, and then padded. Pick up with 55% cotton and 53% T / C, dry at 110 ° C. for 2 minutes, and heat treat at 170 ° C. for 1 minute.

Then, it was washed with JIS L 1092 3 · 3 (1-C) method and tumbler dried for 30 minutes at a temperature of 60 ° C.

Table 1 shows the performance test of the fibrous fabric processed by the water and oil repellent treatment method according to the water repellent JIS L 1092 · 5 · 2 method and the oil repellent AATCC-118 method.

(However, MF, BP-11 and SU-125F are block type crosslinking agents in the form of white powder, MF and BP-11 are block isocyanate type crosslinking agents, and SU-125F is an ethylene amine type crosslinking agent.)

As shown in Table 1, in Examples 1 to 7, the water repellency and oil repellency of the cotton and T / C is perfect at the beginning, the effect is reduced depending on the degree of washing, but the effect is maintained for a long time.

Another embodiment of the present invention is applied to a golf pants or a formal skirt or the like that requires maintaining the classy like a formal pants.

As described above, the water-repellent dress pants according to the present invention are made of fabric processed so that there is no gum (gum), thereby preventing the damage caused by the liquid in the surrounding environment, thereby providing the effect of maintaining the quality as a suit. .
