A Simple Test Method For Moisture Absorption And Sweat Perspiration Fabrics.

The moisture absorption and sweating finishing fabrics are made of moisture absorption and sweat perspiration finishing materials. The main components of moisture absorption and sweat perspiration materials are block copolymer of polyethylene glycol and polyphenyl two formic acid glycol (CH2-CH2-O) n- (PET) - this hydrophilic polymer is compatible with polyester fibers and gives fiber hydrophilic effect.

It can also give the following excellent properties to fabric at the same time:

1, sweat absorption breathability:

The fabric finished by this product has good sweat absorption, good air permeability, excellent wearability, moisture absorption and quick drying. It can remove sweat and moisture from the skin surface.

Fabric drying, airtight and no sweat.

2, hydrophilic and antistatic properties: the fabric finished by this product has excellent hydrophilicity, good antistatic performance, little electrostatic effect, no dust absorption, certain antifouling property and easy washing.

3. Softness:

Soft and smooth, comfortable handle and elegant style.

How to test the performance of moisture absorption and perspiration?

CNAS accreditation items: AATCC 79-2010, water absorbency of textiles, test method for surface absorbency of ASTM D4772-2009 thick pile fabric (water flow test method), test method for water absorbency of GB/T 22799-2009 towel products

1, Mao FA method:

Capillary effect, or capillary effect.

The wool effect test is generally used to detect the pretreatment effect of textiles.

In particular, two kinds of plain dyeing methods, namely rolling and pad dyeing, are used to test the uniformity of water absorption in the left, middle and right parts, and the uniformity of water absorption of the yarn before, after, and after dyeing.

The specific method is to measure the specified width of the fabric or yarn, a section of suspension fixed, a section of water or 0.5% Potassium Permanganate solution at a specified temperature, to test the specified time of water or water.

The rising height or the time required to rise to the specified height is expressed in cm or sec.

The equipment is relatively simple:

2. Drip method:

Drip method is generally used.

Rapid detection of water absorbency, for example, when the third party inspecting the goods, can quickly test the water absorbency of textiles with drip method.

The specific method is to drop a drop of water in the textile according to the specified height, and record the time of the water droplet being absorbed by the stopwatch in seconds.

(1ml is about 18-20 drops, so 1 drops of water is about 0.05ml.

For a demanding customer, the drip method will require instant suction (less than 1 second).

3. Settlement method:

The sedimentation method is the time to test the required area of fabric to sink into the water, for example, the water absorption test method of the national standard towel is the sedimentation method.

The specific method is to cut out the prescribed quantity of fabric in different parts, and then put it in the water according to the specified height, and record the time when the fabric completely sink into the water with a stopwatch. Remember, it must be completely submerged.

Sedimentation is also expressed in seconds. The smaller the value, the better the water absorbency.

For more than 60 seconds, it is usually expressed in >60 seconds.
