Description

Functional clothing providing comfortable fit and manufacturing method thereof }

The examples below relate to functional clothing that provides a comfortable fit and manufacturing method technology thereof.

Recently, as interest in wellness culture has increased around the world, outdoor activities have become popular and demand for outdoor activities has increased. Outdoor clothing is gaining great popularity among consumers as the latest trend in all sports and leisure activities. , demand in that market is increasing dramatically.

Materials to be applied to such outdoor clothing require a lot of functionality. In particular, they require moisture permeability, waterproofing, lightweighting, thinness, and stretchability for convenience during sports and leisure activities.

In general, moisture-permeable waterproof fabric refers to a fabric that has the characteristic of allowing water in the form of vapor to pass through and not allowing water in the liquid state to pass through. These moisture-permeable and waterproof fabrics are mainly used in outdoor clothing such as mountaineering clothing or ski clothing. Clothing using the moisture-permeable waterproof fabric discharges sweat in the form of water vapor generated from physical activity to the outside and prevents water in the form of water droplets, such as rainwater, from penetrating into the clothing.

Technology development for these moisture-permeable and waterproof fabrics has been steadily progressing since the 1960s and accelerated with the development of Gore-Tex ^® in the mid-to-late 1970s, and various technological developments to improve its performance are still in progress.

Depending on the manufacturing method, these moisture-permeable waterproof materials can be roughly divided into a coating type that forms a film and a laminating type that bonds thin films. The coating type has fine pores on the fabric in water. A wet coating type that forms a polyurethane coating layer, and a resin composition containing a highly volatile organic solvent is coated on the fabric to a certain thickness and then heat treated to volatilize the volatile organic solvent to form a porous polyurethane film layer on the fabric. It can be classified into dry coating type.

Conventional technologies for the moisture-permeable waterproof material include Japanese Patent Application Publication No. 5-124144, which discloses a moisture-permeable waterproof sheet manufactured by bonding a non-woven fabric composed of a porous polyethylene film and heat-sealable fibers with heat and pressure in connection with a laminating method, and L-lysine and There is a Japanese Patent Application Laid-Open No. 3-213581, etc., which discloses a moisture-permeable waterproof fabric with excellent abrasion resistance manufactured by laminating a moisture-permeable film made of polyamino acid-based polyurethane containing more than 0.1% of powder made of organic acid reactants onto the fabric.

In addition, Republic of Korea Patent Publication No. 10-2012-0086149 discloses a base layer including a porous film layer and a base fabric layer; Preparing a moisture-permeable waterproof fabric including a nanoweb layer laminated on the porous film layer and a fabric laminated with a porous film; Preparing a nanoweb manufactured by electrospinning; and a laminating step of laminating the nanoweb to the porous film on the fabric.

However, in the case of the manufacturing method of the moisture-permeable waterproof material disclosed in the above prior arts, environmental pollution problems arise due to the use of organic solvents, and in addition, since most fabrics are used, it is impossible to make it ultra-light and ultra-thin, and it lacks functionality such as stretch. There is a problem.

Gore-tex (Gore-tex) is a fiber that was invented by R.W.GORE of Dupont in the U.S. and was given the name GORE-TEX. Teflon resin, which is resistant to heat and chemicals, is stretched and heated to form countless small, It is a material with thin pores, and when added to other materials or fabrics, it has a definite waterproof effect that does not make it wet or damp when moisture is injected from the outside, and is designed to immediately discharge the injected moisture to the outside.

In this way, Gore-Tex is not strictly the same as regular fibers. It is a method of bonding Gore-Tex to general fibers and is characterized by attaching it to the clothing of the hospital. The nature of Gore-Tex is that the pores are smaller than water molecules and larger than water vapor. The Gore-Tex itself is difficult to process into clothing, and it is important to attach the inner lining to the clothing, and it is important to provide comfort and have moisture permeability that quickly permeates moisture generated from the body when attached to the Gore-Tex outer fabric.

In the present invention, the present invention was completed by using an existing functional fabric such as Gore-Tex and applying a special lining to manufacture a clothing material that has a comfortable and soft fit, has a moisture permeability effect, and has excellent elasticity.

Example 1. Functional clothing material with comfortable fit

Gore-Tex fabric, which is waterproof and made of Teflon, was obtained from GORE Korea. The thickness of the Gore-Tex fabric is 0.10 mm and the density is 2.1-2.3 g/ml.

Nano silica of 10 to 50 nm was treated with phenyl trimethoxysilane to obtain surface modified nano silica particles.

90% by weight of thermoplastic polyurethane resin, 8% by weight of the surface-modified nano-silica particles, 1% by weight of silver chloride, and 1% by weight of zinc oxide were mixed and added to an extruder to melt. By melt spinning at a spinning speed of 3,500 m/min in a circular spinneret, yarn with a circular cross section was obtained.

A polypropylene/polyester hot melt adhesive was prepared with a curing temperature of 150°C and a viscosity of 200 mPa·s. It was applied to the polyurethane yarn using a dot screen.

The Gore-Tex fabric and polyurethane yarn were combined in a compression roll. The combination was performed at 2 bar and 110°C. Afterwards, clothing material was manufactured by drying in a hot air dryer at 130°C for 15 minutes.

Comparative Example 1. In Example 1, silver chloride is not included and 9% by weight of surface-modified nano-silica particles are included.

Comparative Example 2. In Example 1, zinc oxide is not included and 9% by weight of surface-modified nano-silica particles are included.

Comparative Example 3. In Example 1, silver chloride and zinc oxide are not included, but 10% by weight of surface-modified nano-silica particles are included.

Experimental Example 1. Physical property evaluation

The physical properties of the test pieces manufactured through the examples and comparative examples prepared as described above, namely air permeability, water resistance, moisture permeability, tensile strength, and peel strength, were measured in the following manner and the results are shown in Table 2.

1) Air permeability: The air permeability of the test specimen was measured in accordance with KS K ISO 9237, where the test area was 20 ㎠ and the pressure was 125 Pa.

2) Water resistance: The water resistance of the test specimen was measured according to KS K 0591 (low water pressure method). The water resistance is the resistance of the fabric to water leakage or submersion. It measures the height of the water column until 3 water droplets are visible by applying pressure to the surface of the fabric with a water column. Check whether The thicker it is, the higher the water resistance, but for functionality, both moisture permeability and water pressure resistance must be high. Water pressure was measured based on 600 mmH2O.

3) Water vapor transmission rate: The water vapor transmission rate of the test specimen was measured using KS K 0594 (calcium chloride method). In other words, the moisture permeability measures the amount of moisture that passes through an area of 1 cm 2 for 24 hours. Measure the initial weight, leave it in a constant temperature and humidity room (24 ℃ 65%), and measure the weight 24 hours later to check the degree to which moisture has escaped. At this time, the area of the moisture permeable cup is 0.00283 m 2, the height of the moisture permeable cup is 25 mm, the measured temperature is 40 ± 2 ℃ and the relative humidity is 90 ± 5 % RH.

4) Tensile strength: The tensile strength of the test specimen was measured according to KS K 0520 (Grabbe method).

5) Peel strength: The peel strength of the test specimen was measured according to ASTM D 2724.

Air permeability (cc/cm 2 /sec) Water resistance (mmH2O) Water vapor permeability (g/m 2 /24hr) Tensile strength (kg/cm 2 ) Peel strength (g/cm 2 ) Example 1 1.1 9,300 5,500 83 110 Comparative Example 1 0.8 8,400 5,300 71 103 Comparative Example 2 0.7 8,800 5,200 75 101 Comparative Example 3 0.6 8,200 5,100 72 99

As above, it can be seen that in the present invention, the simultaneous addition of silver chloride and zinc oxide acts synergistically to improve moisture permeability and other properties of clothing materials. Accordingly, it appears that Example 1 has a moisture absorption and quick drying effect.

Experimental Example 2. Elasticity evaluation

The strength and elongation of the examples and comparative examples prepared above were measured according to the test standard of KS K 0642, 8.14.1 A method (strip method) and are shown in Table 2.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Cutting strength (N) 197.3 185.2 182.4 176.4 Breaking elongation (%) 53.2 45.3 41.2 33.4

As mentioned above, all of Example 1 had excellent elasticity, and this is expected to be the result of the combination of excipients added during the production of lining polyurethane.
