Abstract
The invention discloses a neutral cellulose washing back-to-old finish technology for jean. The method comprises the following steps of: adding 1.0-1.5 owf percent of neutral cellulose, adjusting the pH value to 7-8, adding 0-0.5 kilogram of floating stone, putting the jean into the mixture, treating at the temperature of 40-60 DEG C according to the bath ratio of (1:10)-(1:15) for 80-120 minutes, adding a chlorine-containing bleaching agent, inactivating for 10 minutes, washing, adding a whitening agent and a softening agent, drying, baking and ironing. With the method for performing back-to-old treatment by using neutral cellulose, the jean is high in processing quality, high in production efficiency and low in environment pollution; the available equipment range is wide; damage to a fabric is low; the flexibility and the drapability of a fabric are high; abrasion to equipment is low; and light and thin fabrics can be processed.
Description
Technical field
The invention belongs to the textile dyeing and finishing technical field, relate to the denim finishing technique, old finishing technique is returned in the neutral cellulase washing that is specifically related to a kind of denim.
Background technology
Jean can be in fashion countries in the world, keep unfailing status, except having unique charm wear-resisting, well-pressed, comfortable and easy to wear, the more important thing is because rough bold and unrestrained, the appearance effect that is rich in third dimension and soft and graceful sense that jean is given after returning old processing obtain the favor of various hierarchies of consumption and all ages and classes level.It is to make denim have the critical process of individual style that denim returns old finishing technique.The washing of traditional stone mill arranges the restriction due to factors such as technological process are long, technological requirement is higher and finishing effect is relatively poor, be not suitable for the trend of modern textile development, development along with the enzyme finishing technology, the exploitation of New-type adjuvant, denim returns old arrangement processing larger development on the basis of traditional handicraft, develop into the cellulase stone mill by traditional stone mill washing and arrange.
Summary of the invention
Old finishing technique is returned in the neutral cellulase washing that the invention provides a kind of denim, returns the effect of old arrangement to improve denim.
Biology enzyme is called as biocatalyst, is the protein that a class has catalysis.Compare with general catalyst, the catalytic efficiency of biology enzyme is 10 of general organic catalyst
3-10
6Doubly; The biology enzyme selectivity is strong, and reaction condition is gentle, does not need the violent condition such as high temperature, high pressure, strong acid, highly basic, and is minimum to ambient influnence.
It is cellulase that the biology enzyme stone mill arranges the enzyme of selecting, and cellulase is that a class has the enzyme of degradation capability to cellulose fibre, cellulose macromolecule can be hydrolyzed to short chain, low molecular oligosaccharides and glucose.Because the enzyme molecule is very large, therefore can not be penetrated into fabric, hydrolysis is only carried out at fabric face.Return old arrangement with cellulase, basically solved the problem that exists during the float stone washing arranges, also give simultaneously the style of fabric uniqueness.By the ablation of cellulase to fiber surface, make that fiber surface is worn, dyestuff is stripped from, produce the outward appearance of washing stone mill, thereby reach the imitative old sense effect that denim has.If in conjunction with stone mill, style is special.
Old finishing technique is returned in the neutral cellulase washing of denim of the present invention, comprises the steps:
Add the 1.0owf%-1.5owf% neutral cellulase, regulate the pH value to 7-8, add the float stone of 0kg-0.5kg, put into denim, process 80min-120min under the condition of 40 ℃-60 ℃ of temperature, bath raio 1:10-1:15, add chlorine bleaches, inactivation is processed 10min, rinses, add brightening agent and softener, dry drying, whole scalding.
Preferably, described neutral cellulase addition is 1.2owf%.
Preferably, described float stone addition is 0.2kg.
Preferably, process 100min under the condition of temperature 50 C, bath raio 1:12.
Return old arrangement with neutral cellulase and have that crudy is good, production efficiency is high, environmental pollution is few, the optional equipment scope is wide, the flexibility of, fabric little to fabric (especially crack of stone line, corner and mark) damage and drapability is good, equipment attrition is few, can the advantage such as process to frivolous fabric.
The specific embodiment
Below in conjunction with embodiment, old finishing technique being returned in the neutral cellulase washing of denim of the present invention is described in detail; thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
