Super Imitation Cotton: Dyeing And Finishing Of Yi Lun Cotton / Yi Lun Fabric

It has natural fibers and

Characteristics.

The fiber is embedded in the CO - NH - chain segment, which is flexible and has the handle of cotton. Under the friction, the hairiness is easy to break and not easy to pilling.

Cotton / polyamide fiber has the advantages of easy dyeing, softness, anti pilling, moisture absorption and quick drying.

The fiber has reached mass production, and there are 10000 tons of continuous production equipment.

From the development direction,

The larger area of application is the casual wear, including shirts, trousers, and trousers.

Jackets and coats.

Other applications include sports, home textiles and special style textiles.

Mass production process

Turn the cloth to the seam head, then roll the enzyme to stack, then cook, bleach to shape, then mercerizing to dyeing.

Customer requirements

The zonal breaking strength is greater than 420 N, the shrinkage rate is less than -2.5%, the finished product density is 150 g/m2, and the finished door width is 150 cm.

Matters needing attention

The products are contained in polyamide fibers, so they are in progress.

The characteristics of polyamide fiber must be considered in processing.

In the process of boiling and bleaching, low temperature scouring and bleaching process is adopted to reduce fiber damage. The setting temperature should not be too high (not more than 180 g/L), otherwise the handle will harden; the mass concentration of mercerized alkali should not exceed 180 g/L, so as not to affect fabric strength.

Dyeing process

Dip dyeing, pre drying, drying, baking, baking, drying, rolling, reducing, evaporating, steaming (102 degrees), washing, soaping, hot water washing, cold water washing, drying.

Matters needing attention

(1) polyamide fiber is not resistant to high temperature. Therefore, low temperature disperse dyes can be used to dye polyamide fiber. The temperature disperse dyes can also be dyed, but the temperature can not exceed 180 degrees. The baking temperature is best controlled at 170~175 C.

(2) to control the temperature of pre drying and drying, prevent the drying of the cloth from excessive heat.

Finishing process

Drying, moisture absorption and sweating finishing

Matters needing attention

(1) it is advisable to control the temperature of finishing after drawing at (155 + 5) centigrade.

(2) control the widening and down door width to ensure that the door width is 148 cm after precompression.

(3) before using the moisture absorption and sweating finishing agent, wash the material pipe, material barrel and material trough to prevent the effect of other auxiliaries on moisture absorption and sweat perspiration.

The cotton / polyamide fiber sample test and the large production practice show that the cotton / polyamide fiber finished product can obtain soft handle, and the anti pilling effect and color fastness and strength are all well controlled by controlling the temperature and alkali mass concentration of each key point in the production process.

Now tens of thousands of meters have been produced, which can meet the requirements of customers.
