Description

TECHNICAL FIELD

[0001] The present application relates to the field of cashmere drying, in particular to a cold dryer for cashmere drying. BACKGROUND

[0002] Cashmere, also known as sheep cashmere, is woven by a circular knitting machine. After being woven, the gray cloth is dyed, and then subjected to a variety of complex processes such as drawing, combing, shearing, and shaking. The front of the fabric is drawn, and the cashmere is fluffy and dense, but not easy to shed or pill. Instead, the drawn hair is sparse and uniform, and the fluffy elasticity is excellent. The composition of cashmere is generally polyester, and the hand feeling is soft.

[0003] The processing procedures of cashmere are as follows: cashmere yarn (ground yarn) → hank yarn → weaving → gray cloth inspection and repair → pre-shaping → dyeing (printing) → softening → drying → setting → grabbing → combing → shearing (ironing) → shaking → finished product setting → inspection → rolling and packaging → warehousing.

[0004] In the drying stage, cold drying or hot drying is used. Cold drying is less harmful to cashmere than hot drying. Cold drying uses a cold dryer, which generates dry cold air through a heat exchange device. The dry cold air enters the cold drying box to dry the cashmere inside. The dry cold air absorbs the moisture on the cashmere. In actual production, multiple layers of cashmere are generally arranged in the direction of the cold air to improve the utilization rate of the cold air. However, since the number of layers of cashmere is fixed, when the cold drying effect is found to be poor in actual production, the air volume can only be increased to adjust. This greatly reduces the flexibility of the cold dryer. SUMMARY

[0063] The working principle of a cold dryer for chenille drying:

[0064] The dry cold air from the heat exchange device (not shown) enters the air guide main pipe 321, and then is discharged from the air guide branch pipe 322. Then, all the air flow drives the air flow driving impeller 332 to rotate, so that the dry cold air is sprayed upward through the several layers of the shake wool 50 directly above. This process takes away the water vapor on the shake wool 50, and then the air flow returns to the heat exchange device (not shown) through the air exhaust pipe 17 to be heat exchanged again to become dry cold air, so as to be re-entered into the air guide main pipe 321 for the next round of drying.

Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
