AI Technical Summary

Benefits of technology

The technical effect of this new design is improved heat dissipation for electronic devices due to an increase in surface area between layers caused when multiple small bubbles are formed inside each other during manufacturing process or use after assembly. This increases the amount of airflow within the device while maintaining its overall size.

Problems solved by technology

This patented technical solution described by our company relating to improving garments' ability to absorb and release perspiration without causing them getting wet during rapid movements such as exercise activities like running or jumping.

Embodiment 1

[0043] Using 110dtex-48f-PET composite fiber (8-lobe ordinary PET weight ratio is 75%, easily soluble PET weight ratio is 25%) and 84dtex-144f-PET false-twisted yarn are woven on a 28G double-sided knitting machine under conventional conditions. The double-sided tuck structure is used, so that the PET false twist yarn is exposed on the surface layer, and the composite fiber is exposed on the inner layer. After scouring to remove oil and intermediate setting, caustic soda is used to reduce the weight, so that the easily soluble PET is completely dissolved to form an 8-leaf yarn. Then it is dyed according to ordinary PET knitted fabric, processed by water absorption, and after finishing and shaping, the weight is about 140g / m 2 of knitted fabrics.

[0044] Scouring conditions: 0.2% surfactant solution was treated at 85°C for 20 minutes, and the intermediate setting was set at 190°C for about 2 minutes.

[0045] Use 0.1% maleic acid solution to treat at 120°C for 30 minutes, dr...

Embodiment 2

[0048] Except that the ordinary PET in the composite yarn has a 10-leaf shape, the others are the same as in Example 1.

[0049]The inner layer yarn in the obtained knitted fabric is 100% 10-lobe PET yarn, accounting for 47% of the whole fabric; its monofilament fineness is 2.9 times that of the outer layer yarn, and the monofilament specific surface area is that of the same denier PET yarn. 6 times, the surface-to-surface diffusion area ratio is 3.6:1; the contact coldness value is 1.26 W / cm2.

Embodiment 3

[0051] Using 84dtex-48f-PET composite fiber (6-leaf type ordinary PET weight ratio 75%, easily soluble PET weight ratio 25%) and 84dtex-144f-PET false twisted yarn are woven on a 28G double-sided knitting machine, and the rest are the same as in Example 1 . The obtained gram weight is about 130g / m 2 of knitted fabrics.

[0052] The inner layer yarn in the obtained knitted fabric is 100% 6-lobe PET yarn, accounting for 40% of the whole fabric; its monofilament fineness is 2.3 times that of the outer layer yarn, and the monofilament specific surface area is that of the same denier PET yarn. 4 times, the surface-to-interior diffusion area ratio is 3.3:1; the contact coldness value is 1.24 W / cm2.

Abstract

The invention discloses cool sweat-absorbent quick-drying knitted fabric and application of the cool sweat-absorbent quick-drying knitted fabric. The cool sweat-absorbent quick-drying knitted fabric is double-faced knitted fabric, the surface layer of the knitted fabric is made of fine-denier or superfine-denier PET yarn, the inner layer is partially or completely made of multi-blade type fracture surface PET yarn, the number of blades of the multi-blade type fracture surface PET yarn ranges from 5 to 10, the multi-blade type fracture surface PET yarn is 15-90% of the whole fabric, the filament number of the multi-blade type fracture surface PET yarn is 1.1-5.0 times that of the PET yarn on the surface layer, and the filament specific surface area of the multi-blade type fracture surface PET yarn is 1.2-10 times that of PET yarn the same as the multi-blade type fracture surface PET yarn in filament number. The ratio of the water surface diffusion area to the water inner diffusion area of the knitted fabric is (2-8):1. After a person wears a sport suit made of the cool sweat-absorbent quick-drying knitted fabric, the person feels soft and cool when the skin makes contact with the inner layer of the suit, and does not feel stuffy or wet after sweating.
