Abstract

The present invention relates to a superabsorbent towel, pile yarn is a combination yarn of cotton yarn and 4-leaf PET yarn, the branch tissue is made of 4-leaf PET yarn.

In the present invention, since the cotton yarn constituting the pile yarn protrudes longer than the four-leaf PET yarn, it absorbs moisture from this portion quickly and then spreads and spreads through the capillary tube of the four-leaf PET yarn, so the moisture absorption and diffusion are excellent.

Therefore, it does not give moist feeling than cotton towel and always gives a soft feeling of comfort.

The superabsorbent towel of the present invention has a water diffusion area ratio of 1.3 or more.

Description

High Absorbent Towel

The present invention relates to a superabsorbent towel that is excellent in absorbency and moisture diffusion and maintains a comfortable state at all times by reducing the moist touch caused by moisture during use.

Most conventional towels are made of cotton because the cotton material is natural and has a soft touch and good absorbency.

The term "washing" includes all the activities of contacting body parts with water, such as swimming, bathing and showering, and the "towel" refers to the tools used to remove water from the body before and after washing. Regardless of its size or shape.

Towels for this purpose should be soft to the touch, there should be no foreign matter, and above all, the good absorbency should be able to quickly absorb and diffuse moisture after use.

The reason why cotton is most commonly used for towels so far is due to the significantly higher process moisture content compared to common fiber materials.

However, cotton-based towels have low static water absorptivity, which makes them uncomfortable at the time of initial use. It has the disadvantage of being stiff.

In order to improve this disadvantage, there is a case in which post-processing such as hygroscopic processing is performed in parallel, but such hygroscopic processing has a drawback that the material's inherent touch is lowered and durability for washing is poor.

Therefore, the object of the present invention was devised to solve the above problems, it does not lag behind the towel of the conventional cotton material, high moisture diffusion, high dryness, it is possible to maintain a soft touch even by increasing the number of washing To provide an excellent washable superabsorbent towel.

1 is an enlarged cross-sectional view of a polyethylene terephthalate long fiber yarn used in the present invention.

2 is an explanatory diagram showing a state in which a cotton yarn protrudes from a pile yarn of a towel;

The present invention will be described in detail by way of illustration.

The present invention consists of a paper tissue (1) and pile yarn (2) floating on the upper portion of the paper tissue (floating).

In the present invention, the pile yarn 2 is a twisted yarn that combines a cotton yarn 2a and a polyethylene terephthalate long fiber yarn 2b (hereinafter, abbreviated as 4-leaf PET yarn) having four protruding cross sections. The tissue 1 is made of polyethylene terephthalate long fiber yarn 2b having four protrusions in cross-sectional shape.

The 4-leaf PET yarn 2b of the present invention has a long capillary tube 2c formed between the protrusions.

The fabric of the towel according to the present invention can be both a woven fabric and a knitted fabric, but more preferably a warp knitted fabric.

Towels of warp knitting tissue have better shape stability than circular knitting products, so there is no problem of thread unraveling even after a part of the towel is broken, and the productivity is high and the price is low.

In the towel of the present invention, as shown in Fig. 2, the pile yarn 2 protruding to the surface is made of a twisted yarn of cotton yarn 2a and 4-leaf PET yarn 2b, but the post-processing treatment such as dyeing and heat setting the fabric When the 4-leaf PET yarn (2b) causes the contraction, the cotton yarn (2a) portion naturally protrudes to form a form in which the cotton yarn (2a) portion is extended longer from the pile yarn (2).

In this case, the cotton yarn (2a) protruding long when using the towel absorbs the water first, and then the moisture is quickly transferred through the capillary (2c) formed in the adjacent 4-leaf PET yarn (2b) The superabsorbent towels have excellent moisture absorption and diffusivity, so they can always give a soft and comfortable feeling compared to cotton towels that give a damp feeling.

The superabsorbent towel of the present invention has a water diffusion ratio of at least 1.3 or more because the water diffusion ratio is excellent as described above when the water towel between the surface where the water droplet is dropped and the opposite surface is 1.0.

The present invention will be described in more detail with reference to the following examples.

In addition, the following method was used for measuring various functionalities.

[Measurement of static water absorptivity]

After making the sample 25 cm in length and 2.5 cm in width, the absorption height of water per unit time was measured by the method of JISL1096B method, and water absorption was compared with the average value of 5 times.

[Measurement of Dryness]

After making the sample so that the width × length to 7.5 ㎝ × 7.5 ㎝, it is left in a constant temperature and humidity room for one day and then the weight (Wo) is measured, immersed in a distilled water bath of 27 ℃ ± 2 ℃ sufficiently immersed for 30 minutes and dehydrated for 10 seconds Measure the weight Wa.

While drying the sample in this state at room temperature, the weight (Wb) is measured every 10 minutes until the moisture is completely dried and no more change in weight to calculate the moisture dry amount.

Repeating this five times, the average value of the moisture drying amount is calculated according to the following formula.

Initial amount of remaining water = Wa-Wo

Water content remaining after 10 minutes = Wb-Wo

Drying amount after 10 minutes (Z10) = (Initial remaining water content)-(Remaining water content after 10 minutes)

Drying amount after 20 minutes (Z20) = (remaining moisture after 10 minutes)-(remaining moisture after 20 minutes)

※ Repeat drying every 10 minutes.

[Measurement of Absorption]

After making the sample so that the width × length to 7.5 ㎝ × 7.5 ㎝, it is left in a constant temperature and humidity room for one day and then the weight (Wo) is measured, immersed in a distilled water bath of 27 ℃ ± 2 ℃ sufficiently immersed for 30 minutes and dehydrated for 10 seconds After measuring the weight (Wa), calculate the absorption based on the following equation.

[Measurement of Diffusion]

After making the sample so that the width × length is 7.5cm × 7.5cm, it is allowed to stand in the constant temperature and humidity room for one day, and then 0.3cc of water is dropped at the height of 2cm from the towel surface to measure the diameter of water diffusion from the opposite surface.

Example

A pile letter was prepared from a 4bar warp knitting machine using a plywood yarn prepared by combining 150 denier / 144 filament polyethylene terephthalate long-fiber combustible with 30 cross-sections shown in FIG.

The pile letter was processed by dyeing and processing a general cotton and polyester composite product to prepare a super absorbent towel of the present invention.

In order to evaluate the functionalities of the towels thus manufactured, a comparative evaluation was performed with cotton towels on the market in accordance with the above evaluation method, and the results are shown in Table 1.
