Abstract
The invention provides a preparation method of a novel blended superfine dustless fabric and the prepared dustless fabric. The preparation method comprises the following main steps: polyester silks and polyester polyamide superfine fibers with 1: 2 of the mass ratio are mixed and woven by a knitting machine to prepare a gray fabric; the gray fabric is fed in a dye vat by 1: 5-7 of the bath ratio; penetrating agent, sodium hydroxide, EDTA-4Na and degreasing agent are added in the dye vat; the cleaning is performed in a manner of discharging while washing; acetic acid is used for dipping; the cleaning is performed again; detergent is added; and the gray fabric is cleaned again in the manner of discharging while washing. According to the preparation method of the blended superfine dustless fabric provided by the invention, the prepared novel dustless fabric has such characteristics as excellent wear resistance, cleanness and decontamination capacity, effectively reduces the cost, and is simple in technological process.
Description
Technical field
The invention belongs to non-dust cloth field, relating in particular to is a kind of new no-dust cloth by terylene and polyester-nylon composite superfine fibre blending, for replacing the bright and beautiful composite superfine non-dust cloth of washing of industry routine.
Background technology
Non-dust cloth is a kind of chemical cloth that is widely used in electron-optical medical treatment semiconductor equipment, the cleanliness factor of itself, absorbability, dedusting, ABRASION RESISTANCE are had to very high requirement, in row, generally use terylene non-dust cloth at present or wash the compound ultra-fine non-dust cloth of brocade.Terylene non-dust cloth competitively priced but dust removing effects is general, and rough surface easily abrades sophisticated product surface.And polyester-nylon composite superfine fibre non-dust cloth absorbability, dust removal performance are excellent, surface is fine and smooth is difficult for scratch sophisticated product surface, but expensive, product cost is increased greatly, therefore be not widely adopted yet.
In addition, the defect that the non-dust cloth that current non-dust cloth preparation method makes exists the aspects such as cleannes, dust adsorption capacity, ABRASION RESISTANCE and dirty removal capacities to be difficult to meet the demands toward contact, and production process is comparatively loaded down with trivial details.
Summary of the invention
For making up the deficiencies in the prior art, the invention provides the preparation method of the ultra-fine non-dust cloth of a kind of blending, the new no-dust cloth that the method makes not only has the characteristics such as good ABRASION RESISTANCE, cleanliness factor and dirty removal capacities, and it effectively reduces cost, and technological process is simple.
The present invention is for reaching its object, and the technical scheme of employing is as follows:
A preparation method for the ultra-fine non-dust cloth of novel blending, comprises the steps:
1) terylene thread that is 1:2 by mass ratio and polyester-nylon superthin filament carry out mixed weaving with knitting machine, make grey cloth;
2) in dye vat, add RO water, according to the bath raio of 1:5～7 by step 1) grey cloth that makes puts in dye vat;
3) in dye vat, add bleeding agent, NaOH, EDTA-4Na and degreaser; The temperature of solution in dye vat is risen to 105～110 ℃, be incubated 30～40 minutes; Bleeding agent, NaOH, EDTA-4Na and the degreaser concentration in dye vat is respectively 1～1.5g/L, 6～10g/L, 1～1.5g/L, 2～4g/L.
4) in limit side washing row mode (that is, outwards discharging the solution in dye vat in the time of cleaning), clean the grey cloth in dye vat, cooling
To 50 ℃, be incubated 2～5 minutes;
5) in dye vat, add acetic acid to soak;
6) again in limit side washing row mode, clean grey cloth, then the water in drained dye vat;
7) in dye vat, add washing agent, and inject RO water in dye vat, be warming up to 120～125 ℃, be incubated 55～65 minutes;
8) again in limit side washing row mode, clean grey cloth;
9) in dye vat, inject RO water, be warming up to 60 ℃, be incubated 8～15 minutes;
10) in limit side washing row mode, clean grey cloth, cooling simultaneously, is incubated 8～15 minutes after being cooled to 40 ℃;
11) in dye vat, inject RO water, and again in limit side washing row mode, clean grey cloth, then the water in drained dye vat, goes out cloth.
Its specification of described terylene thread is 50D/72F, described its specification of polyester-nylon superthin filament is 75D/35F, use terylene thread and the polyester-nylon superthin filament collocation blending of this specification, make non-dust cloth best results, not only cost is well controlled, and the non-dust cloth making is all better in the performance of the aspects such as ABRASION RESISTANCE, cleanliness factor and dirty removal capacities.
Further, step 5) in, the concentration of acetic acid is 0.3～0.5g/L.
Preferably, step 5) in, with acetic acid, soak 4～7 minutes.
Preferably, step 7) in, the concentration of washing agent is 1～2g/L.
The present invention's bleeding agent, degreaser, washing agent used all selected the conventional product of the art, for example, bleeding agent can adopt JFC, and degreaser can adopt the LZC301A of degreaser ZJ-C301, the science and technology production of the connection village etc., washing agent can be used liquid detergent, as white cat board liquid detergent.
The ultra-fine non-dust cloth of novel blending that second aspect present invention provides a kind of basis preparation method as described above to make.
Polyester-nylon superthin filament those skilled in the art described in literary composition are called again polyester-nylon composite superfine fibre or polyester-nylon superthin silk.
RO described in literary composition (Reverses Osmosis) is the water of counter-infiltration.Bath raio described in literary composition is the routine techniques term of the art, and it refers to the ratio (quality) of fabric and solution.
Technical scheme provided by the invention, has following beneficial effect:
The present invention passes through certain proportion blending by terylene thread and polyester-nylon superthin silk, again grey cloth is washed according to the washing process of optimizing, the aspects such as its absorbent properties of the non-dust cloth making, ABRASION RESISTANCE and cleanliness factor and dirty removal capacities can reach the standard that requires of superfine fibre, can substitute on a large scale superfine fibre.
Non-dust cloth prepared by the present invention, its raw materials used cost is low compared with superfine fibre dust-free cloth, but grey cloth cleanliness factor is higher, and washing process is simplified, and greatly limit reduces the cost of non-dust cloth.
The present invention repeatedly adopts limit side washing row's mode can prevent contamination in the water-washing process of grey cloth, can improve to greatest extent cleaning degree.
The non-dust cloth called after Pylon that present inventor makes preparation method of the present invention.
The specific embodiment
Below in conjunction with embodiment, technical scheme of the present invention is described further:
