• Starching agents for use in domestic starching should meet various requirements, especially the following:
• A. a cloth or clothing treated with such a starching agent should allow an iron to slide thereon smoothly
• a cloth treated with a starching agent should have an excellent flexural stiffness or bending resistance
• a cloth treated therewith should have an excellent compressive elasticity, that is, it should have a massiveness or feeling of fullness.
• lubricants for instance, a silicone oil and a polyoxyethylene glycol in, respectively, Japanese Patent Publication Nos. 17093/63 and 18593/63.
• a starching agent containing such a lubricant has a good working property and affords animproved finish with respect to ironing.
• a starching agent containing a smaller amount of such a lubricant provides, to a cloth treated therewith, superior slipperiness to an iron, as compared to an agent not containing such a lubricant, but it is not satisfactory in the above properties (B), (C) and (D), namely, adsorption of the starching agent by a cloth immersed in a starching solution, stiff ness orv flexural resistance and massiveness of the finished cloth.
• the present invention has for its object to solve such problems and to provide a starching agent of an improved quality. That is, the starching agent of the present invention is well adsorbed by a cloth and affords a finished cloth which is excellent not only in slipperiness to an iron, but also in the feelings of stiffness and massiveness. It is an important feature of the present invention that the lubricant of the present invention is sufficiently-effective even if it is used in a small amount .of 5 wt. percent or less, based onthe weight of the effective starch component, while the known lubricants must be used in amounts-of at least 1.0 wt. percent to obtain completely satisfactory results.
• the present invention provides a starching composition which is characterized by the fact that it contains from 0.5 to 5 percent by weight of at least one compound .of'a molecular weight of 4,500 to 12,000, which compound is obtained'by adding ethylene oxide to a compound selected from the group consisting of C C higher alcohols, (preferably saturated fatty alcohols), C Ci higher saturated fatty acids and C aklylphenols (alkyl C C As the higher alcohol, there may be used any higher alcohol from lauryl alcohol of C to octadecyl alcohol of C although it is preferred to use cetyl alcohol and octadecyl alcohol.
• the higher fatty acid there can be used any of those from lauric acid of C to stearic acid of C although it is preferred to use palmitic acid and stearic acid.
• the alkylphenol there can be used any of those from octylphenolsof C to dodecylphenols of C
• the compound is prepared by adding ethylene oxide to such an alcohol, fatty acid or alkylphenol to obtain molecular weights of 4,500 to 12,000, preferably 7,000 to 9,000.
• the amount of such a lubricant compound of the pres- .ent invention added to the starching composition dance with known practice.
• the ratio of the starching agent to water is generally in the range of from 0.5 to 3 percent, preferably 1 to 2 percent by weight.
• Invention A As an invention which may be compared with the present invention, there is an invention disclosed in Japanese Patent Publication No. 9517/67 (hereinafter referred to as Invention A).
• Invention A relates to a starching composition containing therein 30 to 70 wt. percent, based on the weight of the effective starching components in the liquid starching composition, of a surface active agent of the structure of a random 'or block adduct of ethylene oxide and propylene oxide to a higher alcohol.
• the composition of the present invention differs essentially therefrom especially in the following aspects:
• the present invention is characterized by containing in the starching composition a lubricant in a small amount of 5 percent or less, whereas the Invention A is characterized by containing a lubricant in a large amount of 30 to 70 percent.
• the lubricant in the present invention is only an assistant, whereas the lubricant in Invention A is regarded as a base material rather than an assistant, in view of its high concentration.
• starching composition of the present invention differs from that of the Invention A by comparing the properties of a starching composition containing a small amount of a lubricantof the present invention with those of another starching compositioncontaining a small amount of the lubricant of the Invention A, for instance, as illustrated in the following examples, in which are compared starching compositions comprising a starch paste, carboxymethylcellulose, polyvinyl alcohol or like base containing therein 1.5 percent by weight of (1') a lubricant according to the present invention and (2) the adduct of the Invention A.
• the lubricant of the lnvention A is a relatively low molecular compound of a molecular weight of 1,000 to 2,000, as is understood from the description of its specification, and it has a high surface activity as indicated by a surface tension of an order of 30 dyne/crn as shown in the following Table 1, whereas the lubricant of the present invention is a high molecular weight compound of a molecular weight of at least 4,500 and, therefore, it has little surface activity as is indicated by its surface tension of about 50 dyne/cm as shown in the Table 1.
• the lubricant of the present invention does not serve as a surface active agent, but rather serves as merely a water-soluble polymer.
• a lowermolecular weight compound of the same type of structure as the lubricant of the present invention has a remarkably high surface activity and is unsuitable for use as a lubricant for the preparation of the starching composition of the present invention.
• Starch based composition In 100 parts of water were suspended 100 parts of potato starch, 2.3 parts of sodium carbonate and 1.5 parts of a lubricant. The suspension was then processed at temperatures within the range of 130 to 140C. by means of a drum dryer to convert the starch into the astate and the composition was ground by means of a grinder into a powder of a particle size of 60 mesh or less to obtain a product.
• Polyvinyl alcohol based composition In 100 parts of water were dissolved 5 parts of a polyvinyl alcohol (Gohsenol GL05, Nippon Synthetic Chemical Industry Co.) and 0.075 part of a lubricant with stirring to obtain a starching liquid.
• a polyvinyl alcohol Gohsenol GL05, Nippon Synthetic Chemical Industry Co.
• Carboxymethylcellulose based composition In water were dissolved 5 parts of a carboxymethylcellulose (supplied by Shikoku Kasei K.K.) and 0.075 part of a lubricant to obtain a viscous solution and the solution was then sufficiently dried by means of a drum dryer at 100C. and then was ground by means of a speed mill into a powder of a particle size of 60 mesh or less.
• the thickness A of the pile was measured under a load of 10 g. After being left under a load of 600 g for 3 minutes, the pile was again subjected to measurement of its thickness A under a load of 10 g. Calculating the elastic recovery from the ratio A /A the compressive elasticity ratio of each test piece was calculated, with reference to a control sample assigned an arbitrary value of 100.
• the results are summarized in the following Table 3. The larger the value in the Table, the greater is the compressive elasticity, i.e., the better is the feeling of massiveness.
• Table there are also summarized the results of tests of feeling of massiveness as determined by a test panel of 10 persons who manually felt the samples. The test panel evaluated the feeling of massiveness by assigning to each sample a quality value in accordance with the following standard. The larger the value; the better is the feeling of massiveness.
• the starching composition of the present invention is excellent in all of the desired properties, namely, (1 capacity of being adsorbed by cloth, (2) ironing property, (3) flexural resistance and (4) feeling of massiveness of a cloth treated therewith and in all-round rating.
• the surface tension was determined at C. on a 0.01 percent by weight aqueous solution by means of a du Nouy surface tension balance.
• the concentration was determined by considering theconcentration of a bles 3 and 4, these terms have the same meanings.
• a starching agent selected from the group consisting of starch, polyvinyl alcohol and carboxymethylcellulose and (2) from 0.5 to 5 percent by weight, based on the weight of starching agent, of at least one lubricant of a molecular weight in the range of from 4,500 to 12,000 selected from the group consisting of ethylene oxide adducts of a higher alcohol containing 12 to 18 carbon atoms, ethylene oxide adducts of a higher fatty acid containing 12 to 18 carbon atoms and ethylene oxide adducts of an alkylphenol containing 14 to 18 carbon atoms.
