The present invention is described in detail below:
The object of Tencel fabric pre-treatment is identical with other fabrics, namely the impurity such as slurry, finish, pigment, spot on grey cloth is fully removed, the fabric of processing is made to have good wettability, soft feel and good wearability, for dyeing and stamp processing provide suitable semi-products.But due to the characteristic of Tencel fiber self and the requirement of finished product, need pre-treatment process and the technological parameter of applicable Tencel fiber own characteristic, the present invention has determined its pre-treatment processing process and technological parameter through a large amount of.
(1) singe
The surface of Tencel fabric is the same with COTTON FABRIC, and surface has irregular fine hair to exist, and the object of singing is exactly remove these fine hair of fabric face, improves the fineness of fabric face, is beneficial to fibrillation and ferment treatment in postorder processing.Because Tencel is easy to fibrillation, have very high bloating tendency, and have very strong " memory ", any folding line namely formed under hygral expansion state first all can be fixed up by lasting, so the fire extinguishing after singing generally adopts steam smoothering, and open width caustic dip fire extinguishing that need not be conventional, under hygrometric state, produce folding line to reduce Tencel fabric, singeing adopts two positive two instead, speed of a motor vehicle 90-100m/min, burner temperature 900-1000 DEG C, progression 3-4 level of singing.
(2) alkaline oxygen bath process
Tencel fiber belongs to regenerated celulose fibre, without natural impurity on cloth cover, for artificial impurity such as the slurries on fabric, alkaline oxygen bath can be adopted to carry out impurity elimination bleaching.Alkali destarch all has good removal effect to chemical sizwe, natural slurry, finish etc.; Hydrogen peroxide also has the impurity elimination effect on strengthening fabric concurrently; Caustic soda can also take the hydrogen bond between the strand of fiber amorphous region apart, even enters crystal region segmental defect place and makes swelling of fiber.When alkali is washed away, when fabric stands swelling again, then can not reach original puffed degree, so leave in fabric " free space ", thus fabric stiffness index in wet processing is below reduced, the danger producing folding line reduces.
Alkaline oxygen bath belongs to the short route pre-treatment of moving back and boiling drift, and it can reduce scratch because easily producing under humid tropical condition mechanism repeatedly and wrinkle.The present invention determines to adopt cold dome abbreviated system by a large amount of tests, and determines suitable technological parameter.
The optimised process prescription of alkaline oxygen bath process is:
(3) fibrillation
Fibrillation is a key property of Tencel fiber.Fibrillation is exactly that microfiber (diameter is less than 1-4um) stretches out along fiber surface cracking, and it is the distinctive performance of Tencel fiber.The generation of fibrillation comes between fabric or fabric and intermetallic wet friction, and the fento split is close to transparent, forms the effect of white as " frost " at fabric face, and excessive fibrillation, fento can be entangled, makes fabric face be full of ball top.For dyeing and finishing processing, the fibrillation of Tencel fiber has double effect, on the one hand by effects such as the machineries in control dyeing and finishing processing, produces the fabric of different aesthetic feeling, as peach face; On the other hand, for making Tencel fabric have bright and clean outward appearance, and have " machine washable " performance, the fibrillation in must effectively preventing fabric from taking, this can utilize physics or chemical method to process realization.The former belongs to " utilization of fibrillation " and the latter belongs to " control of fibrillation ", except the minority products such as peach face, other a large amount of Tencel fabric product all must avoid the appearance of fibrillation, for this reason, effectively to prevent and the method for removing fibrillation mainly contains Mechanical course, ferment treatment, crosslink finishing and ready-made clothes arrangement etc.This research, mainly for general T encel fabric product, first makes the abundant fibrillation of fiber, then it effectively to be removed by the method for ferment treatment and make cloth and bright and clean, thus ensures the colour brightness of painting cloth.
The fibrillation of Tencel fabric is important step in whole process, has larger impact to the following process of product and wearability.The object of fibrillation processing is lax and under rubbing state, make fiber after moisture expantion, being subject to mechanical external force effect makes micro-fibril peel off from main fibre layer, and then the staple fiber ends of yarn interior is discharged as far as possible, then adds a work through ferment treatment etc. the cilium of exposure is removed.Fibrillation process can improve feel and other dyeing and finishing processing characteristicies of Tencel fabric, if but fibrillation deal with improperly easily cause fabric pincher and fibril uneven, fibrillation is insufficient, easily makes it in aft-loaded airfoil and ready-made clothes washing process, again produce fibril, pilling, have a strong impact on the outward appearance of aft-loaded airfoil and ready-made clothes, so good fibrillation and ferment treatment must be carried out to it, to ensure that the generation that fabric no longer includes villus in aft-loaded airfoil and ready-made clothes use is made a noise.In fibrillation process, Mechanical course and selecting of auxiliary agent are the primary conditions controlling original fiber degree, and affect factor mainly treatment temperature, the time etc. of fibrillation, adopt the method such as alkaline agent, low bath raio, raised temperature, reinforcement mechanical friction to be all conducive to fibrillation simultaneously, make the fine hair of exposure be easy to remove with cellulase in rear operation, the performance of fibrillation fabric is mainly comprehensively weighed by feel and the powerful index declined.
Lubricant (wrinkle preventing agent) can be added when fibrillation, it effectively can reduce feel and to harden, prevent the generation (especially PURE YARN FABRIC) of fabric folds, wetting agent is generally fatty acid ester, polyamide derivative, phosphate derivative etc., their foaming characteristics are little, and the present invention is Ciba Cibafluid C through research employing.
The present invention determines to determine suitable technological parameter by a large amount of tests:
Technological process is: at 45-55 DEG C of obtain solution (Cibafluid C and Na2CO3), add Tencel fabric, is warming up to 80-90 DEG C of insulation 60-80min, cooling cleaning with 2 DEG C/min.
(4) ferment treatment
There is various fine and closely woven cilium in the Tencel fabric surface after fibrillation, easily winding mutually, knotting balling-up, make its surface very coarse, affect finished appearance and quality.The object of cellulase treatment Tencel fabric is exactly remove the cilium formed in fibrillation process, makes fabric face bright and clean, improves fabric feeling, improves drapability and the dyeability of fabric.Cellulase is the enzyme of a class high selectivity, 1.4-key in energy catalyzing hydrolysis cellulose macromolecule chain, by its process, the fibril on Tencel fabric comes off, eliminates cilium, improve its dyeability and wearability, meanwhile, in processing procedure, the termination of enzyme effect is also very important, because cellulase continues degraded to cellulose will cause the excessive damage of fabric, in like manner, washing after ferment treatment must fully, make the cilium come off thoroughly remove, to reduce dyeing defect.
Due to special construction and the performance of Tencel fiber, general cellulase preparation can not be made usually
The effect that people is satisfied, and ferment treatment process must strictly control, otherwise it is uneven that cilium can be caused to remove, especially can cause the loss of fabric strength and make it lose to take value.Therefore, the present invention is by a large amount of screening, and selected use holoenzyme, also claims conventional fibre element enzyme, be made up of, the synergy of these three kinds of enzyme components multiple restriction endonuclease, excision enzyme and cellobiase, very strong to " aggressiveness " of cellulose fibre.Use in its best serviceability temperature and pH value to make cellulase.For ensureing that fabric obtains best processing effect, any surface finish and without excessive degradation, larger damage can not be subject to, the present invention determines to determine suitable technological parameter by a large amount of tests:
Adding Na2CO3 after being disposed is 2g/L, makes pH9-10, is then warming up to 80 DEG C and makes enzyme deactivation 10-15min, last 60 DEG C of cleanings.After ferment treatment, fabric feeling obviously improves, and fineness improves.
The present invention has the following advantages: Tencel fabric is after pre-treatment processing, and the ultimate strength fall of fabric is little, but capillary effect significantly increases, and the ability of fabric absorption dye material improves.There is not Boardy Feeling in the product obtained after normal dyeing, fibrillation, uneven dyeing, color and luster wither secretly, the defect of the bright and clean difference of cloth cover and easy wrinkle.
