Description

Rubbing color fastness tester {Rubbing color fastness tester}

In the friction fastness tester of the present invention, in order to test the friction fastness of the fabric, the specimen part for fixing the fabric separates and combines the specimen fixing top plate and the specimen support at once by the operation of the one-touch clamp, and the specimen part prevents the fixed fabric from slipping , It relates to a friction fastness tester that can adjust the reciprocating distance of the friction rod according to the test standard, and prevents the friction rod from being damaged by impact during descent by operating the friction rod in a cylindrical manner, which is installed, operated, and stopped.

In general, when dyed fibers, fabrics, or fabrics are rubbed, the dye on the surface moves to the rubbed object.

Contamination moving from the surface of the dyed material to another object by friction is one of the important problems occurring in fibers, fabrics, and fabrics, and is a very important quality item, and can be evaluated as friction fastness for textile products.

That is, friction fastness is an item that is a measure of the degree of staining of dyes due to friction with other products when using dyed textile products.

Friction fastness is largely divided into dry rubbing (dry rubbing) fastness and wet rubbing (wet rubbing) fastness. It is an item about the degree of contamination that moves from the surface of dyeing material to another object by friction in a wet state.

The rubbing fastness test is a method of measuring the degree of staining of dyes by friction with other products when a consumer uses a dyed textile product by using a rubbing fastness tester.

There are various methods such as the crockmeter method, the vertical crockmeter method, and the academic-type friction fastness test method, and it is tested using a friction fastness tester.

The Crockmeter method is a method of determining the degree of contamination after wrapping a dry or wet white cotton cloth in a friction rod with a diameter of 1.5 cm located on the bottom of a friction rod attached to a crank with a load of 900 g and reciprocating 10 times in 10 seconds for a distance of 10 cm. am.

The Vertical Crockmeter method is a method to determine contamination by wrapping a dry or wet white cotton cloth in a friction bar with a diameter of 1.5 cm and a load of 1,134 g at a fixed position and rotating it forward and backward 20 times.

Hakjin-type friction fastness is a method of determining the degree of contamination after a 2 × 2 cm friction rod with a load of 300 g is wrapped with dry or wet white cotton cloth and moved 100 times at a rate of 30 reciprocating movements per minute over a distance of 10 cm.

On the other hand, in the conventional friction fastness tester for testing the friction fastness, the fabric is seated on the specimen pedestal, and the specimen part coupled to the specimen fixing top plate for fixing it is driven by a motor to rub the fabric fixed to the specimen part. It is formed in a structure in which a white cotton cloth is wrapped around a friction rod for reciprocating linear motion and a friction rod located on the bottom surface of the front end of the friction element.

Conventional friction fastness testers have a problem inconvenient for the user to use because the fabric is seated on the specimen support and the specimen part that couples the specimen fixing top plate is tightened with a bolt type.

In addition, the specimen part should maintain the flat unfolded state of the fabric, but in the process of reciprocating the frictional motion, the fabric itself cannot be fixed in the first unfolded state, and wrinkles are generated due to movement by frictional force. There is a problem that needs to be repeated.

In addition, the conventional friction fastness tester has a problem in that the reciprocating distance of the friction member cannot be adjusted according to national and international standards.

In addition, in the conventional friction fastness tester, the operator manually rotates and lifts the friction material in an upward direction in order to seat the fabric on the specimen part or wraps the white cotton cloth around the friction rod, and then the operator manually rotates the friction material downward to return it to its original state. In the process of pushing and rotating, there is a problem in that the lower part of the friction rod made of acrylic material is damaged by the impact caused by the strong collision with the specimen support by carelessness.
