Wrinkle Resistance And Wrinkle Retention Of Fabrics

Crease resistance of fabrics

Crease and

Wrinkle - the wrinkling property of a fabric when it is rubbed and rubbed. It is called wrinkle.

Crease resistance - the ability of fabric to resist flexural deformation caused by rubbing is called crease resistance, also called crease (wrinkle) resilience, which is closely related to the elasticity or plasticity of the fabric.

The main factors affecting the crease resistance of fabrics are discussed.

Fiber properties, fiber geometry: rough, round, smooth fiber wrinkle recovery is better.

Fiber elasticity: the property that fiber can recover after deforming is a key factor for fabric wrinkle resistance. The greater the value, the higher the wrinkle recovery of fabric.

Such as spandex and wool fabrics have good crease resistance.

The friction property of fiber is the second essential factor of wrinkle resistance. Theoretically speaking, no slip occurs between fibers, i.e. no energy consumption, and no slip recovery is found. However, it will lead to large changes in fibers, or no slip between fibers, no energy consumption, which is conducive to the recovery of fibers when they are released.

Yarn structure: yarn twist is moderate, fabric wrinkle resistance is good.

Fabric geometry: fabric thickness has a significant effect on crease recovery, and crease recovery of thick fabrics is better.

Environmental conditions: when the temperature and humidity increase, fiber material is more plastic, and the frictional resistance between fibers will also become larger.

The way to improve crease resistance is to follow two basic mechanisms of wrinkle resistance: high elasticity of fibers and low friction or elastic connection between fibers.

Fabric pleats retention

A general concept of pleated retention.

Pleated retention - the wrinkles (including striations and creases) formed by ironing, and the degree of preservation after washing are called pleated retention.

Pleated retention is essentially a form of thermoplastic properties of most synthetic fabrics.

Since most synthetic fibers are thermoplastic polymers, they can be generally treated by heat setting, so that all kinds of pleat, grain or creases that are needed for the use of such fibers or fabrics blended with this type of fibers can be obtained.

The main factors that influence pleats retention.

Basic factors: stability of fiber structure and stability of fiber structure after setting.

The thermoplastic and elastic fibers, thermoplastic and elastic fibers, can form good wrinkle and other deformation during heat setting.

Although the use of external force produces new deformation, once the external force is removed, the ability to return to the original fold or crease or rolling shape is better.

Polyester and acrylic fabrics have the best wrinkle durability, and the wrinkle durability of nylon fabrics can also be achieved. The wrinkle durability of vinylon and polypropylene fibers is poor.

The twist of the yarn and the thickness of the fabric, the twist and the thickness of the fabric are better after the ironing.

The temperature, pressure and moisture content of fabric, the moisture content of fabric and the durability of the pleat are very great. When the moisture content is constant, the crease effect is the largest, and the increase of moisture content will cause the surface temperature of the iron to decrease, and the crease effect will be reduced.

When the iron temperature is raised, the most suitable moisture content moves to high direction.

Ironing time, at suitable temperature, when thick fabrics are ironed 10s, a good crease can be obtained in general, and the crease is balanced at 30s.

After finishing with resin, non hot-melt fabric is treated with resin.
