5.??Neutralization - ?? Normal temperature - - 6.5-7.0
13
???? Production Process
14
??? ?? Stage 1 Padding
? ???????????????????? To ensure the liquid are
being absorbed and spread evenly in short time
15
??? ??(?) Stage 1 Padding (Cont)

• ???????????
• The benefits of half-soaking and half-showering
• ????????
• Ensure liquids are evenly spread
• ????,??????????
• Safe operation, barrels are equipped with
  automatic sensors
• ???????
• Save manpower and cost

??? Liquid Tank
??? Shower Tank
??? Refill Barrels
16
??? ??(?) Stage 1 Padding (Cont)
??????????? Padder ensures rolling liquid rate is
even
???????????????,?????????? Adopt specially
designed structure to control tension and roll
edge
????? Extension Device
?? Padder
????? Spiral Extension Roll
17
??? ?? Stage 2 Yarding
??????????????????? Concentration , Emulsion,
Saponification, Decomposition, Oxidation,
Swelling
???????????????????????????????? The alkali and
surface active agent of the liquid and hydrogen
peroxide slowly react to the impurities and
pigment
????????? Place sealed fabric trolley in stacking
area
????4?? Piled up for 4 hours
18
??? ?? Stage 3 Steaming
? ????????,??????????,?????????,?????? Steaming
is a quick catalytic process -gt accelerates
decomposition activity of the hydrogen peroxide,
shorten yarding time and improves production
efficiency
???????? Knitted Fabric under Steaming
19
??? ?? (?) Stage 3 Steaming (Cont)
????????????,?????????????,????????????????? Prehe
ating device reduces fabrics temperature
difference when enters steam box and prevents
adverse effect caused by temperature
difference ???????????????????????? Two rolling
knitted fabric devices to ensure steam are even
20
??? ?? Stage 4 Washing
? ??????????????????????????????,??????????????,??
????? Washing place decomposed, degraded and
emulsification impurities in continuous cleaning
water. It washes residues away and meets the
semi-finished products requirements
21
??? ??(?) Stage 4 Washing (Cont)

• ??????????????????

?????????????Introduction of the Post-treatment
of Rope Color-fixing Softer Machine
31
??????????? Post-treatment of Rope Color-fixing
Softer Machine

• ????????????????
• latest dyeing post-process equipment of
  Jintian
• ?????,???????????????,???????,
  ????????????,?????????,????????? ????????????
• In traditional production, color stabilizing,
  softening process within the dyeing
  machine is time and energy consuming. It fails to
  meet the new trend of energy saving and
  environmental protection, thus rope
  color-fixing softer machine is developed
• ????6????5?????????????????????? ???????
• Can complete color stabilizing and softening
  process shortly with 6 groups of rolls, 5
  groups of liquid tank and refillable additives

32
???? Competitive Advantage

• ?????????,?????????????,????, ??????
• Improve utilization rate of dyeing machine,
  shorten the time of dyeing process, reduce
  energy consumption and enhance productivity
