Abstract
The invention discloses a kind of low damage wool fabric Placer tin deposit technique.The strength damage that tradition Sand Wash Process brings wool fabric is large.Wool fabric after ACID DYES or reactive dyeing loads in acidproof sludge proof mesh bag by the present invention, and then put into industrial washing machine, control ph is at 4.2-4.8; Be warming up to 60-80 DEG C, the strong oxidizer adding 0.5-10%o.w.f in industrial washing machine carries out sand washing, and described strong oxidizer is potassium permanganate or compound potassium permanganate sustained release; Be cooled to 45-55 DEG C of washing, add the softener of 4-6%o.w.f; And then dewater, dry.The present invention adopts the synergy of specific pH value and strong oxidizer, makes wool fabric reach significantly imitative old finishing effect, and effectively prevent the strength damage that traditional Sand Wash Process brings.
Description
Technical field
The present invention relates to wool fabric or wool ready-made clothes finishing field, specifically a kind of low damage wool fabric Placer tin deposit technique.
Background technology
After stone mill denim fabric is in fashion, washing, sand washing fabric are arisen at the historic moment, and the sand washing processing of silk, viscose glue and COTTON FABRIC is very general, and less to the sand washing research of wool fabric.The sand washing of usual wool fabric is placed in the mesh bag of terylene by fabric or ready-made clothes, after preparing sand washing bath, packed fabric or ready-made clothes put into sand washer with alkali, acid or neutral salt (as zinc chloride, calcium sulfate and calcium chloride etc.); Then, depending on required fabric napping degree, fabric or ready-made clothes are rolled 30-120min in sand washing bath.The effect of sand washing agent is to make fiber because of expanded and thicker, increases fiber friction of motion in a relaxed state, so that surface is because of impaired and napping, so traditional woolen sand washing essence is exactly napping.
For many years, style of missing old times or old friends is always by industry is praised highly, and particularly recreation is more and more subject to people's attention, and misses old times or old friends fabric then because its comfortable and cordiality unique on color and flower pattern becomes the main flow fabric of leisure wear.Fabric of missing old times or old friends is realized by the selection of raw material and the postfinishing process such as washing, ENZYME WASH, forms the appearance effect of nature cordiality, and based on cotton, fiber crops, silk, and majority is realized by ENZYME WASH, and ENZYME WASH is large to Wool Fibre Damage.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming the existence of above-mentioned prior art, provides a kind of low damage wool fabric Placer tin deposit technique, with the strength damage effectively avoiding traditional Sand Wash Process to bring wool fabric.
For this reason, the present invention adopts following technical scheme: a kind of low damage wool fabric Placer tin deposit technique, and its step is as follows:
1) wool fabric after ACID DYES or reactive dyeing is loaded in acidproof sludge proof mesh bag, then industrial washing machine is put into; bath raio controls at 1:10-50; at room temperature add pH buffer system; control ph is at 4.2-4.8; make it be strict controlled within the scope of wool isoelectric point, strength damage is minimum;
2) be warming up to 60-80 DEG C, the strong oxidizer adding 0.5-10%o.w.f in industrial washing machine carries out sand washing, and the sand washing time is 10-60 minute, and described strong oxidizer is potassium permanganate or compound potassium permanganate sustained release;
3) cooling discharge opeing, 45-55 DEG C of washing, adds the softener of 4-6%o.w.f, soften handled 10-30 minute; And then dewater, dry, the fabric obtained after oven dry has imitative old style.
Isoelectric point is a kind of key property that protein has, and protein is when its isoelectric point, and the trend or the degree that are dissociated into CATION and anion are equal, in electroneutral, now osmotic pressure, conductance, viscosity, solubility reach minimum, without the repulsion effect between electric charge between protein, easily reunite.Wool is a kind of native protein, and therefore during wool isoelectric point, swelling behavior and chemism reduce, and inhale mollic acid the slowest, have maximum stability and minimum reactivity worth at isoelectric point region wool.Therefore, isoelectric point state is optimal state to alleviating wool damage.
The present invention adopts strong oxidizer in conjunction with the isoelectric point characteristic of wool fibre, develops the low damage Sand Wash Process that a kind of applicable wool imitates old arrangement.The present invention adopts the synergy of specific pH value and strong oxidizer, makes wool fabric reach significantly imitative old finishing effect.Wool fabric after sand washing, has and misses old times or old friends outside style, and feel is more plentiful, soft.Placer tin deposit technique of the present invention is equally applicable to wool ready-made clothes.
As improving further and supplementing technique scheme, the present invention takes following technical measures:
Described pH buffer system preferred acetic acid-acetate buffer system, acetic acid-ammonium acetate buffer system or acetic acid-ammonium sulfate buffer system.
Step 3) in, add the oxalic acid of 0.1-5%o.w.f during washing, oxalic acid is used for the metallic elements such as complexing manganese and remains, and removes potassium permanganate residual on fabric and loose colour.
Step 3) in, the optimum temperature of soft treatment controls at 50 DEG C, and bake out temperature controls at 60-70 DEG C.
Described mesh bag is preferably terylene mesh bag, and acidproof resistance to oxidation effect is good.
Step 3) in, the consumption of strong oxidizer is preferably 2-5%o.w.f, and other organic principle in suitably excessive strong oxidizer energy degradation water, whole process is environment friendly and pollution-free.
Described softener is preferably quaternary ammonium softener or the non-silicone softener of nonionic, and described quaternary ammonium softener is as SAPAMINEFPS or SAPAMINEOC.
Compared with existing wool Sand Wash Process, the present invention has the following advantages:
1) the present invention processes under wool isoelectric point, now wool swelling behavior and active reduction, reduce the effect of oxidant to wool, oxidant is made to mainly act on surface and the dyestuff above thereof of wool, decrease the consumption of oxidant, decrease the destruction of damage to cortex of wool and dye inside, strength damage is little, effectively prevent the strength damage that traditional Sand Wash Process brings.
2) the present invention selects potassium permanganate to be oxidant, and oxidability is strong, and execution that is acid to conventional hair or REACTIVE DYES is obvious, uses and can reach well imitative old effect on a small quantity; Potassium permanganate has sterilization, waste water except functions such as colourities simultaneously, overcomes tradition and uses sulfur-bearing reductant to imitate the old environmental problem brought.
