Abstract
The invention discloses a method for fabricating color-absorbing cleaning pouches or cleaning strips for washing machines in the technical field of light and chemical industry, and the method comprises the steps of firstly preparing 5-10g/L of aminated polyepichlorohydrin or polyacrylic acid water solution, keeping the bath ratio at 15-55:1, heating to 80-100 DEG C, and then forming pre-treatment agent solution; adding 2-7g/L of sodium hydroxide into the pre-treatment agent solution for regulating the pH value; then placing non-woven fabric after cleaning into the solution for carrying out reaction for 20-50 minutes; and finally sewing the non-woven fabric into fabric pouches or fabric strips, wherein the weight of each fabric pouch or each fabric strip is 1-5g. Groups for absorbing dyes are grafted on fibers of the non-woven fabric, and the groups and the dyes faded during the water washing process of clothes are in mutual attraction through the electrostatic attraction role, thereby achieving the effects of rapidly absorbing the dyes in the water and not staining other clothes; and the method is applicable to colored wastewater with the dyes faded during the washing process of the clothes dyed by a variety of dyes, and has the advantages of convenient use, high-efficient color absorption and capability of protecting the clothes and the environment.
Description
Technical field
The present invention relates to the light industry technical field, be specifically related to a kind of suction look clean bag or cleansing bar made from nonwoven fabric, this clean bag or cleansing bar are used for textiless such as washing machine washing clothes.
Background technology
Nonwoven fabric is one of a kind of and human lives articles for use in close relations, the Along with people's growth in the living standard, and nonwoven fabric gets into various fields in life day by day, brings convenience to people's life.The daily clothes of buying; Particularly there is the washing problem that fades mostly in textiles such as dark clothes; When putting into washing machine together and shuffle with other clothing, its dyestuff that comes off is prone to stain other clothes, has destroyed the overall appearance of other clothes; Stain serious clothes and can not wear once more and cause huge waste, the sanitary sewage that contains a large amount of dyestuffs has also caused pollution to environment.Usually, the method that addresses this problem is to add a little salt to reduce the degree of fading, and the clothing that maybe will fade washs separately, but these two kinds of methods have all increased workload, and effect and not obvious.
Summary of the invention
The use in washing machine nonwoven fabric that the purpose of this invention is to provide a kind of adsorbable dyestuff that fades with low cost, easy to use is inhaled look clean bag or cleansing bar.
The technical scheme that the present invention adopts is: preparation 5-10 grams per liter polyepichlorohydrin amine thing or polyacrylic aqueous solution bath raio are 15-55 earlier: 1, form pretreating reagent solution after being heated to 80-100 ℃; In this pretreating reagent solution, add NaOH and regulate the pH value, addition is the 2-7 grams per liter; Nonwoven fabric after will cleaning is then put into solution reaction 20-50 minute; At last the gained nonwoven fabric is sewn into cloth bag or cloth, each cloth bag or cloth weight are that the 1-5 gram gets final product.
The invention has the beneficial effects as follows:
1, the dyestuff that fades in the group of grafting absorbing dye on non-woven fabrics fiber, this group and clothes water-washing process is inhaled through the electrostatic attraction effect mutually, has reached dyestuff in the rapid adsorbed water and the effect of other clothing of not staining.
2, the present invention inhales the look nonwoven fabric and is applicable to the various dyeing clothings laundry colorful wastewater that fades.
3, easy to use, efficiently inhale look, can protect other clothing and environment.
The specific embodiment
Nonwoven fabric is to be made up of fiber orientation or at random, is environment-friendly materials of new generation, has advantages such as powerful good, air permeable waterproof, environmental protection, pliable and tough, nonpoisonous and tasteless and low price.Nonwoven production mainly is polypropylene fibre or terylene with fiber, in addition, also has polyamide fibre, viscose, acrylic fibers, polyethylene or polyvinyl chloride fibre etc.It is raw material that the present invention selects the viscose nonwoven fabric, earlier nonwoven fabric is carried out pre-treatment, then the nonwoven fabric after the pre-treatment is made clean bag or cleansing bar, and detailed process is following:
Earlier the preparation 5-10 grams per liter polyepichlorohydrin amine thing or the polyacrylic aqueous solution, bath raio is 15-55: 1, form pretreating reagent solution after being heated to 80-100 ℃.Nonwoven fabric after will cleaning is again put into this pretreating reagent solution reaction 20-50 minute; Make on the oh group of non-woven fabrics fiber and be grafted with the absorbing dye group; The dyestuff that fades in this group and the clothes water-washing process is inhaled through the electrostatic attraction effect mutually, has reached dyestuff in the rapid adsorbed water and the effect of other clothing of not staining.
Reach the optimal adsorption effect to dyestuff, pretreatment stage must be carried out under alkali condition, therefore; Adopt NaOH to regulate pretreating reagent pH value; In this pretreating reagent solution, add NaOH during the preparation pretreating reagent, addition is the 2-7 grams per liter, makes the pH value be not less than 10.
The gained nonwoven fabric is sewn into cloth bag or cloth; Each cloth bag or cloth weight are 1-5 gram, prepare amount of dye respectively and are the water of 0.5-3% and pour washing machine into, add above-mentioned cloth bag or cloth that the 2-8 gram is sewn into; Other adds calico and carries out mixing, washing; The result is: contain limpid that the water of color becomes, and calico does not have staining, it is obvious to inhale chromatic effect.
