Definitions
- This invention relates to a new and improved process for the continuous bleaching of cotton woven fabrics. More particularly it relates to a process of pro-treating such cotton goods whereby they may be treated with caustic and bleached with hydrogen peroxide in a single continuous storage stage.
- gray woven cotton goods are first subjected to pre-treatment for removal of fabric sizes and finishes, then subjected to a relatively strong caustic soda solution, steamed and stored in a continuous storage system such as a J-box, saturated with a hydrogen peroxide bleaching solution, steamed and stored in a second .l-box at a temperature of ZOO-212 F. and finally washed and dried.
- a relatively strong caustic soda solution such as a J-box
- saturated with a hydrogen peroxide bleaching solution steamed and stored in a second .l-box at a temperature of ZOO-212 F.
- the objects of this invention may be accomplished, in general, by pre-treating unbleached woven cotton goods with an aqueous solution of a surface active wetting agent and a phosphate, rinsing the cotton goods, and then bleaching the same with an alkaline peroxide solution.
- the first step may be carried out by immersing the woven cotton material in an aqueous solution of a surfactant and a phosphate for a short time so that the cotton is thoroughly wet with the solution.
- a surfactant and a phosphate for a short time so that the cotton is thoroughly wet with the solution.
- immersion usually about 1 to 30 minutes immersion is suitable and about 1 to 3 minutes is effective to produce good results.
- a longer period of immersion may be utilized, if desired, especially if the woven materials being treated are heavy or tightly woven. Less than 1 minute may be satisfactory for light or loosely woven materials.
- the temperature of the wet-out should be above room temperature for best results and it is preferred to operate at about 120 to 140 F. Temperatures higher than about 140 F. are satisfactory and excellent results have been obtained at 180 F. However, in most instances temperatures below 180 F. are satisfactory and more economical. At temperatures below about 120 F., difficulty may sometimes be encountered in reproducing results and brightness of the bleached cotton will be lower than obtained with the higher temperature wet-out.
- concentrations of surfactant or phosphate within the range of 0.1% to 1.0% are useful. Preferably about 0.3% to 0.5% is used for best results. Concentrations above 1% may be used but show little or no added advantage. Below about 0.3% a somewhat lower brightness will be obtained.
- Anionic, cationic or nonionic surfactants may be used in the wet-out with equally good results.
- suitable surfactants are the alkoxylated aryl polyether alcohols, polyethylene oxide condensates, sodium alkyl sulfates, sodium hydrocarbon sulfonates, the stearamide of diethylene triamine, fatty alkylol amine condensates, substituted oxazoline, amino alkane sulfates of a fatty acid, sulfonated esters of dicarboxylic acid and alkyl aryl sulfonates.
- the phosphates having utility in the process of this invention are the molecularly dehydrated salts of phosphoric acid, for example, sodium hexametaphosphate, sodium tripolyphosphate and sodium pyrophosphate.
- the woven cotton from the wet-out step be rinsed.
- the rinse water is heated to about the same temperature as the wet-out.
- the woven cotton is bleached with an alkaline peroxide, preferably in the damp condition.
- the cotton is treated with sufficient bleach solution to become thoroughly wet and will in most cases contain bleach solution in an amount equal to about 50% to of the weight of cotton.
- the cotton containing bleach solution is heated, for example, by steaming to temperatures of about 16 to 212 F. or higher if desired and then maintained at the elevated temperature, while preventing evaporation, until the desired degree of bleaching is obtained.
- the cotton may be steamed to raise the temperature of the goods to about 205 to 212 F. and then stored in an insulated i-box for between 30 minutes and 1 /2 hours. At the end of the bleaching period, the goods are rinsed in water until essentially free of bleach solution.
- the usual well-known stabilizers and alkalies for peroxide bleaching may be used, for example, sodium silicate, caustic soda, borax and sodium pyrophosphate.
- the preferred percompound for the bleaching step is hydrogen peroxide.
- hydrogen peroxide other known equivalents for hydrogen peroxide may be used, for example, sodium peroxide, sodium perborate and the like.
- the coneentration of hydrogen peroxide employed will be within the range of about 0.5% to 2.0% (100% H 0 basis).
- Sodium silicate is the preferred stabilizer in the bleach ing step of this invention and, for optimum results, sodium silicate should be used in amounts greater than those commonly utilized in bleaching woven cotton goods. It is preferred to use about 2% to 3% sodium silicate (the 42 Be. silicate regularly used in the textile bleaching trade). Higher concentrations may be used but show no advantage. Less than about 2% silicate may be used but improved results are obtained with 2% or more.
- the preferred alkali in the bleach solution is sodium hydroxide and about 0.1% to 0.8% sodium hydroxide may be used. However, it is preferred to use about 0.2 to 0.6% for best results.
- E 6 The following examples illustrate the invention: xamp e A 25 g. sample of gray woven cotton was immersed Example] directly in a bleach solution containing 1.05% H 0 Samples of gray cotton sheeting weighting 25 g.
- Example 1 Du bhl if ?(653 5::IIIIIIIIIII I 9110 Example? The procedure of Example 1 was followed except that Example; the cotton sample was wet-out in a solution containing 1% olive oil soap instead of sodium alkyl sulfate sur- The proceclure of Example 1 Z repealffd except the factant. Brightness of the bleached sample was 91.4. wet-out solution contained 0.5 Duponol ME and the In an of the above examples using the process of the Phosphates hsted below: present invention, the bleached samples were mote-free or had a mote count of not more than 1 per square foot Phosphate Brightness and an absorbency less than 2 seconds.
- a major advantage of the process of this invention is ggg fi g gi ff fgggfigg 3 ⁇ : that it provides a practical process for bleaching gray Sodium pyrophosphate 911s woven cotton goods without the necessity for extensive sdium hexametaphtlsphate (01113 pretreatments. It is surprising that the combination disclosed herein produces bleached cotton of high brightness, Examplej free of motes and having excellent absorbency in view of the fact that previously known commercial operations hexametaphosphate; the bleach solution 1.05% H 0 xi g to Obtam saitlslactow 3.0% sodium silicate 0.6% NaOH and 0.5% borax.
- Pei-em has primary utility in bleaching gray woven cotton it may Wet-out temperature--80 F. be used in bleaching woven cotton previously subjected to Brightness91.0 various treatments, for example, enzyme desizing, acid Wet-out temperature 140 F.; brightness-91.8 souring, mercerizing or a combination thereof. How- Emm [e 4 ever, it may be necessary for optimum results to adjust P 70 the alkalinity of the bleach formula.
- Example 1 The procedure of Example 1 was followed using a Since it is obvious that many changes and modifications wet-out solution containing 0.5 sodium hexametaphoscan be made in the above described details without dephate and 0.5 Duponol ME for 3 minutes at 140 F. parting from the nature and spirit of the invention it is The bleach solution contained 1.05 H 0 2.0% sodium to be understood that this invention is not to be limited to said details except as set forth in the appended claims.
- alkaline peroxide bleaching solution contains between .5% and 2.0% H 0 between 2% and 3% sodium silicate (42 B.), between 0.1% and 0.8% sodium hydroxide and between 0.3% and 1% borax.
