Degumming process are summarized as follows:
A. A cooking method This method is suitable for spinning twine. Process as follows: the unpacking Xie beam → original Ma Baptist acid → lye → a scouring → washing → fiber fight and washing → acid pickling → washing → dewatering → → drying oil. Customized Garden Flags
Two. Two cooking method this method is suitable for low-spun yarn. The process is: dip the unpacking Xie beam → acid → → washing → washing → first scouring second scouring → pickling → playing fiber and washing → washing → dewatering → dehydration to the oil → → drying.
3. The two cook a bleaching method is suitable for spinning branched yarn. The process is: dip the unpacking Xie beam → acid → → washing → washing → time scouring the second scouring → playing fiber and water washing → bleaching → pickling → Customized Garden Flags washed → dehydration → to oil → dehydration → drying.
4. Two cook two drift method This method is suitable for spinning yarn. The process is: dip the unpacking Xie beam → acid → → washing → washing → time scouring the second scouring → the playing fiber and phenylephrine → pickling → washed → dehydration → to oil → dehydration → drying.
(B) ramie woven material pre-treatment
Ramie fabric pre-treatment, is basically similar to the pretreatment of cotton fabric, composed mainly by singeing, desizing, scouring and bleaching process.
A. Singeing the number of ramie fabric hairiness, ramie fiber rigidity, therefore, singeing than the cotton fabric is more important, otherwise the fabric fluff be prickly. Customized Garden Flags Ramie singeing require high-speed burn through the most appropriate equipment is gas singeing machine, requiring configuration to dual-jet crater or cyclone premixed jet new crater, these crater flame temperature up to 1350 ° C in the hot and fast conditions, Customized Garden Flags which would ensure both burn the fluff, does not damage the fiber, a burn through the crater above the configured not to cold water roller to enhance the penetration of the flame. The singeing recoverable two positive and two anti-speed 80 ~
Two. Desizing, scouring and desizing purpose is to remove the slurry on the fabric and some impurities. The purpose of scouring is to remove the fibers with biological, so that the fabric is absorbent, so that in the adsorption and diffusion of dyes and chemicals. Ramie fabric scouring at atmospheric pressure. Ramie thin fabric, desizing, scouring and one heavy fabric or cotton products, desizing after scouring; ramie and polyester blended fabric, Customized Garden Flags ramie fiber is pre-full unglued, so do not special scouring. Desizing, scouring and the key is to evenly through to the complex to the net. In addition, due to poor ramie resistance to acid, alkali and oxidant, in the formulation process should pay particular attention to. Scouring solution of NaOH
Desizing, scouring and width of continuous steaming equipment, steaming should be in the double liquid crawler steaming box or R steaming box, these devices have the function of steam under cook, capacity large quantity of cloth, steaming time, fabric dipping in lye full, desizing, scouring and more through good effect.
3. Bleached ramie fabric bleach can be used chlorine bleach or oxygen bleach, sodium hypochlorite bleach, dilute solution for a long time bleaching, Customized Garden Flags the bleaching effect of the bleaching effect of a shorter time better, this is because of the ramie fibers were thicker, a short period of time the chemicals are not well soaked . Sodium hypochlorite bleach will produce yellowing phenomenon, which can be resolved by the use of hydrogen peroxide dechlorination. Therefore, using oxygen and chlorine pairs drift is a good process. Ramie fabric treatment process in addition to the thin fabric to the width processing.
