Description

Fabric mercerization equipment for mercerizing range

The utility model relates to the fabric caustic dip facility of dyeing and finishing pretreatment stage chain mercerizer in the braiding industrial production.

The mercerising process is through strong caustic (alkali lye) impregnation process with cellulose fibres such as cotton, fiber crops, make fiber that irreversible swelling take place and cause that the fiber lattice parameter changes, part changes the amorphous region into by the crystalline region, thereby has improved the ability of fiber absorbing dye; Swelling also can be eliminated the internal stress that fiber forms and improve its plasticity in growth course, thereby improves the physical property of cellulose base fiber fabric, as reducing washing shrinkage, increase the fabric door width of cloth, improving fabric sheen etc.

The capital equipment of mercerising process employing at present is a chain mercerizer.The chain mercerizer of existing structure all adopts compact form caustic dip facility (referring to accompanying drawing 1).Fabric 12 is entered by entering arrangment 1, make fabric 12 have a certain amount of caustic lye of soda through the first road alkali immerging device 2, march to jockey pulley 3 and 18～21 cloth rewinder rolls 4 that stretch tight then, jockey pulley 3 applies tension force to fabric 12 warp-wises and produces gloss in the hope of making fabric 12, and the cloth rewinder roll 4 that stretches tight makes fabric 12 and alkali lye that be arranged 45～50 seconds action time.Fabric 12 enters the second road alkali immerging device 5 after cloth rewinder roll 4 outputs of stretching tight under tensioning state.So far finish the caustic dip process, last fabric 12 enters cloth gripper device (not demonstrating among the figure) and carries out tentering and soda.This compact type mercerization technology and equipment are used existing many decades history till today, though over the years equipment is constantly improved to some extent, the principle that the compact form caustic dip is handled remains unchanged.Compact form is handled significant disadvantages: when fabric floods caustic soda under tensioning state, alkali lye is difficult to infiltrate through fiber and only reaches fabric face, owing to be subjected to the restriction of device length, have only 45～50 seconds the action time of fiber and caustic soda, far can not reach the required time of alkali lye and fibration simultaneously.Theory and practice shows that the time fabric of this effect also needs just to make fiber reach swelling effect preferably more than 5 minutes under loose formula condition.So the swelling effect that compact form is handled is neither irregular again thoroughly, except that increasing the fabric sheen, other functions can not be brought into play effectively.

The purpose of this utility model is that the loose formula of setting up a kind of chain mercerizer is banked up and the caustic dip facility of the dual-purpose form of degree of tightness, soaks into the action time of alkali lye and fiber and alkali lye to guarantee fiber, reaches and gives full play to the due every function of mercerization.

The loose formula of the utility model design caustic dip facility of banking up comprises the entering arrangment that is placed in respectively on the mercerizing range frame, the first road alkali immerging device, the mop roller, cutting device, the bank up large cloth containing device of fabric, the second road alkali immerging device, jockey pulley, the some cloth rewinder rolls and make fabric produce essential gloss to the bar milk that fabric applies tension force of stretching tight also make the length of fabric and filling density conform with the product specification requirement simultaneously.Join with the cloth gripper device subsequently.The caustic dip facility of the dual-purpose form of degree of tightness is the design feature of banking up the caustic dip facility based on loose formula, stretch tight and set up a jockey pulley and one group of cloth rewinder roll that stretches tight in addition between the cloth rewinder roll and the first road alkali immerging device at bank up a group of alkali lye facility of loose formula, make fabric behind the first road alkali immerging device caustic dip, both can enter the second road alkali immerging device and make loose formula and handle, and enter the second road alkali immerging device behind the jockey pulley that can pass through to be set up again and the cloth rewinder roll that stretches tight and make compact form and handle by the bank up appearance cloth device of fabric of mop roller, cutting device, loose formula.

The utility model has the advantages that, fabric can be detained 5～10 minutes in large cloth containing device (500～1000 meters) under the tension-free loose formula state, caustic lye of soda can be not only infiltrated fiber thoroughly but also equably, the fiber swelling is abundant, wherein the cellulose quantity that is converted into cellulose can reach the 30%(swelling more fully, and inversion quantity is bigger).The fiber amorphous region increases, thereby has improved the adsorption capacity to dyestuff significantly, and the Dry Sack rate improves, and can save dyestuff, and dyeing vividness and level-dyeing property also are improved.Also basic elimination of the internal stress of intermolecular generation in the cellulose fibre developmental process owing to the separating key of intermolecular most of hydrogen bonds in the loose formula processing procedure, improved the plasticity of fiber, make the fabric door width of cloth be easy to stretch, fabric fully stretches again through the intermolecular hydrogen bond that forms again regularly on new position behind soda and the drying, the corresponding DIMENSIONAL STABILITY that improved has reduced the washing shrinkage of fabric.Used caustic soda concentration also can be reduced to 170～180 grams per liters from 240～360 grams per liters of compact form when mercerising was handled.
