CN103396905A - Liquid bleacher - Google Patents

Abstract

A liquid bleacher is composed of sodium hypochlorite, sodium tripolyphosphate, trisodium phosphate, aluminum potassium sulfate, sodium sulfate, sodium dodecyl sulfate, sodium carbonate, a leveling agent, carboxymethylcellulose and ethanol. The liquid bleacher is prepared through putting the above components in a synthetic kettle, sequentially adding the above chemical raw materials according to proportions, stirring for emulsifying, and putting the obtained product in a finished product pot for use. The liquid bleacher has the advantages of improvement of the bleaching effects of fibers and fabrics, maintenance of the firmness of the fibers, just needing of one-time scouring and bleaching, simple operation and low cost.

Description

Liquid bleach

Technical field

The present invention relates to a kind of chemical products, in particular for the SYNTHETIC OPTICAL WHITNER of garment material.

Background technology

Present cotton, hemp fabric and fiber product thereof, except the hyperchromatic product of part, all need through bleaching, and up to now, SYNTHETIC OPTICAL WHITNER commonly used is three kinds of hypochlorite, hydrogen peroxide and Textones.The bleaching effect of hydrogen peroxide is better, but its poor stability needs stablizer to stablize, and the requirement that stores is stricter, need to be placed on shady place, avoids heavy metal and the oxide compounds thereof such as copper, iron, aluminium, nickel, so the bleaching container is also had to requirement; Though the sodium hypochlorite bleaching effect is good, but its cost is high, and this product is explosive poisonous chemical again; With hypo(chlorite)bleaching, mainly select clorox and Losantin, but the latter easily produces calcium cold shot defect on fabric, with hypochlorite, can not once scouring and bleaching, and needs through postprocessing working procedures such as acidleach, influential to the fibre strength of fabric.

Goal of the invention

The object of the present invention is to provide a kind of liquid bleach of preserving of producing under normal temperature condition, it can improve the bleaching effect to fiber, fabric, can keep again the fiber firmness not reduce, and only need once scouring and bleaching, and operation is simple, and expense is cheap.

Summary of the invention

Liquid bleach of the present invention its by: clorox, tripoly phosphate sodium STPP, tertiary sodium phosphate, aluminum potassium sulfate, sodium sulfate, sodium lauryl sulphate, sodium carbonate, levelling agent, hydroxyl methylcellulose, ethanol form, and wherein each weight ratio of constituents is: clorox: tripoly phosphate sodium STPP: tertiary sodium phosphate: aluminum potassium sulfate: sodium sulfate: sodium lauryl sulphate: sodium carbonate: levelling agent: the hydroxyl methylcellulose: ethanol is 90-98: 0.2-0.4: 0.1-0.3: 0.2-0.3: 0.2-0.3: 0.1-0.4: 0.1-0.4: 0.2-0.4: 0.2-0.4: 0.2-1.0.

Above composition is put into to synthesis reactor, the ammonia proportioning adds above chemical feedstocks successively, stirring and emulsifying is put into finished pot, can use, adopt liquid brightener of the present invention can improve the bleaching effect to fiber, fabric, can keep again the fiber firmness not reduce, only need once scouring and bleaching, operation is simple, and expense is cheap.

Claims (1)

1. liquid bleach, it is characterized in that: it is by clorox, tripoly phosphate sodium STPP, tertiary sodium phosphate, aluminum potassium sulfate, sodium sulfate, sodium lauryl sulphate, sodium carbonate, levelling agent, the hydroxyl methylcellulose, ethanol forms, wherein each weight ratio of constituents is: clorox: tripoly phosphate sodium STPP: tertiary sodium phosphate: aluminum potassium sulfate: sodium sulfate: sodium lauryl sulphate: sodium carbonate: levelling agent: the hydroxyl methylcellulose: ethanol is 90-98: 0.2-0.4: 0.1-0.3: 0.2-0.3: 0.2-0.3: 0.1-0.4: 0.1-0.4: 0.2-0.4: 0.2-0.4: 0.2-1.0.
