ジャーナル フリーMany kinds of surfactants and other agents were tested for the purpose of finding the agents which had a strong softening effect upon raw silk. Results obtained:
(1) Every non-ionic surfactant had a weak softening effect upon raw silk.
(2) Raw silk was considerably softened by the treatment with the mixed solution of a non-ionic surfactant and a higher alcohol.
(3) Some cationic surfactants showed considerably strong softening effects, but even in these cases the small amount of moisture contained in the treated raw silk played also an important role.
(4) The relation between the numbers of carbon of the higher alcohol in the treating solution and the softning effect upon raw silk was not clear.
(5) Some ampholytic surfactants had a considerably strong softening effect upon raw silk.
(6) Ethylen glycol and its polymers had weak softening effects.
(7) Dimethyl urea had a weak softening effect, while tannic acid had, on the contrary, a hardening effect on raw silk.抄録全体を表示PDF形式でダウンロード (307K) -

ジャーナル フリーA method to compare the resistance to elongation of different fibres was divised, a tester was made, the examination showed:
1) The distribution of elongation degree of raw silk seems to be normal, and it can be considered that the longer the length of the test piece is, the smaller the error becomes.
2) There is practically no error due to the defect of the tester.
3) The mean value obtained by using this tester for lowering modulus of elasticity of raw silk caused by its treatment with urea solution is almost the same with that obtained by using KS Senimeter.
4) The variation of measured value by this tester seems almost the same with that obtained by Instron tensile tester, when the test pieces are the same in length.
5) Experimentally the comparison of meduli of elasticity of two kinds of raw silk of different deniers may be done by modifiing the deniers.抄録全体を表示PDF形式でダウンロード (835K) -

ジャーナル フリーThe Auther has shown that a single pulp fiber strength can be casily measured with considerable accuracy by the modified Du Nouy Tensimeter in which a supporter dish is replaced by chuck and the diameter of piano wire increased up to 1, 2mm. With this modified tensimeter, He found that the breaking strength of a single pulp fiber of Kraft insulation paper for high voltage cable is 27 to 29kg/mm2 for 125μ paper, 35_??_37kg/mm2 for 100μ paper, and 37_??_40kg/mm2 for 70 and 40μ paper.
The method of determining cross sectional area is especially important in the measurement of the single pulp fiber strength.抄録全体を表示PDF形式でダウンロード (282K) -

ジャーナル フリーIn order to compare fine structure of transitional area, an acetate grade cotton linter pulp and a viscose grade prehydrolyzed pine sulfate pulp were steeped in 4_??_18% sodium gydroxied solutions at 20°C, washed and dried, and then subjicted to acid hydrolysis. Lateral order distribution curves showing the fine structure of transitional area in total, and each in the direction of length and width of micells (highly ordered regions) were obtained from the change in amount of micells (known as crystallinity by hydrolysis method), leveling off degree of polymerization. and rate constant of hydrolysis, respectively. X-ray diffraction intensity curves of alkali-treated pulps were obtained as auxiliary informations.
Wood pulp has larger amount of transitional area over wide range of lateral order in both directions of micells, while cotton linter pulp has smaller in the direction of length and scarecely in the direction of width of micells. From the results of X-ray diffraction mecsurements, it might be possible that wood pulp has some amount of micells which have especially small crystalline core, being decrystallized with sodium hydroxide solutions under 9%, while cotton linter pulp has no such fine structure.
X-ray measurements showed the presence of small amount of cellulos II lattice in the commercial pulps, and they increased gradually with increased concentration of steeping sodium hydroxide solution from 4 to 8_??_9%. These may be formed from relatively highly ordered regions due to rearrangement effect of swelling and deswelling.抄録全体を表示PDF形式でダウンロード (450K) -

ジャーナル フリーThe fastness of dyeing with dispersed dyes depends on how deeply the particles of dyes are inserted. The microscopic test of the cross section of the dyed fiber has been widely used to know the distribution of dyes in fiber. Expecting that only the surface of polyester fiber dissolves in alkali treatment and leaves the inner part of the fiber unswollen, and a rigid stucture of Tetoron prevents. dyes from penetrating into inner part of fiber under ordinary condition, Alkali treatment of Cr treated Tetoron is continued till the combination of dyes with Cr at the surface of tetoron ends. under normal pressure.
The polyester fiber used in this experiment was treated with K2 Cr2 O7 solution for 5hrs at 120°C and washed with water. Several portions of Cr treated tetoron, each 0.5g, were heated in 10% NaOH solution at 85°C changing the hours of the treatment and washed with water, and dyed with Sunchromine Pue Blure B. extra. Weight loss and absorption of dyes were determined. The relation between weignt losses and the time of alkali treatment is shown in Fig. I. The effect of absorption of dyes by Cr treated tetoron on the weight loss is shown in Fig. 2. Point A is a critical point where Cr is contained on fiber. From the weight loss at point A, the penetrated distance of Cr from the surface of fiber was calculated.抄録全体を表示PDF形式でダウンロード (237K) -

ジャーナル フリーIn order to study the effect of chelate formation at cystine bridge in wool on its properties, cystine bridge was broken and then treated with Cu solution to form metallic salt with S and the recombined wool was compared with original wool and the chelated wool in alkali duarability, the changes in S content during alkali treatment and mechanical properties. Thioglycolic acid which. is known to break only cystine bridge in wool without damaging other parts of it was used. Degreased Merino wool was used. Wool was immersied in 0.05M of thioglycolic acid at the ratio. of 1:100 for 4hours at 20°C. and washed with water. The mixture of 50ml of 0.05M Cu(NO3)2, 20ml of 0.5N HNO3, 50ml of 2M KNO3, 50ml of 3% aqueous solution of nonionic surface active agent and 200ml of water was used for Cu treatment. About 15g of wool were immersed in the mixture at 30°C for 67 hours and washed and dried. Alkali solubility was determined in 0.1N NaOH solution at 65°C. The results are shown in Fig. 1.
The recombined wool showed to have nearly same durability to alkali as the chelated wool. It is much improved in alkali resistance in comparison with the original wool. The change of S content during alkali treatment is shown in Table 1. This also shows that the recombined wool has the same tendancy as the chelated wool.
From these results, the combination of Cu ion with S in wool irrespective of S in cystine bridge or S in free state has a relation to alkali durability, therefore chelate formation is preferable.抄録全体を表示PDF形式でダウンロード (316K) -

ジャーナル フリーThe solubility of some dissolving pulps in alkaline sodium zincate solution is studied.
Two components of the solutions used are, one containing 120g/l NaOH, 20g/l ZnO, 2g/l Na2SO3, and the other 120g/l NaOH, 5g/l ZnO, 2g/l Na2SO3. Comparing of the results of the determinations of chain length distribution curves of the pulp, these values of solubilities corresponded to the amount of fractions with the degree of polymerisation below about 300 and about 200, respectively. These results do not agree with the values obtained by T. N. Kleinert. These values are called LZ-20 and LZ-5.
DZ of pulps which means the difference between LZ-5 and LZ-20 corresponds to LZ-5 of aged alkaline cellulose.
LZ-5, however, is not reprisentative of the amount of fraction below the degree of polymerisation 200 in aged alkaline cellulose. It is considered the effect of the structural factors, though it is not certain.抄録全体を表示PDF形式でダウンロード (388K) -

ジャーナル フリーThe application of our automatic draft control system by Ever Even which has the decided neutral zone in controller was performed for our cotton spinning process. This application is classified into two types, one is for double and more deliveries, and the other for single delivery.*
One kind of the former type is the application for automatic draft control of the variation of average sliver thickness produced from drawing frame. This automatic control means the control of long term variation of average sliver thickness produced control means the control of long term variation of average sliver thickness produced and our conventional control method is performed by so-called X-R control chart system.
Form the test by Ever Even, the following are observed:
(1) The variation of average sliver thickness produced from drawing frame #2 is controlled in the range ±0.5% for standard value.
(2) Average counts of yarn is controlled in the same range of drawing sliver the coefficient of variation of yarn counts is about 1.2_??_1.4%. The variation of lea strength for 40S is also decreased and the percentage of lea strength under 50 lbs in controlled lot is about 9% and that of conventional lot is 19%.
(3) The variation of cake weight of control lot is about 1/2 of that of conventional lot.
(4) It is proved by Nyquist criterion that the stability of this control system is maintained.
The short cut of the spinning process by the automatic draft control system for single delivery is proven beneficial by our mill test.
It may be expected that if the draft control system is applied for draft element with single delivery to which some card slivers are fed as the same feed method of comber draw-box. excellent uniform sliver may be produced.

ジャーナル フリーTo investigate the mechanism of dyeing of Vinylon with basic dyes, the absorption isotherms of C. I. Basic Blue 9, C. I. Basic Violet 3, C. I. Basic Bed 2, C. I. Basic Blue 26, C. I. Basic Violet 10 and C. I. Basic Orange 2 in presence or in absence of salt were determined at 80°C.
The isotherms obtained were represented approximately by the following equation which was a linear combination of two functions.
It is considered that in the equation (1), the term K[D]s[S]/1+K[D]s correponds to the dyeing mechanism which takes place by adsorption of dye cations by carboxyl anions in Vinylon, and that the term K′[D]s corresponds to the dyeing mechanism which takes place by solution of dye into the fibre.
By the use of the equation (1), the saturation value, the number of carboxyl groups in Vinylon, can be calculated from the isotherms. The values calculated were ca. 8m. mol/kg fibre. ([D]F and [D]s are the concentration of dye in the fibre and in solution, [S] the saturation value, K, K′ constant).抄録全体を表示PDF形式でダウンロード (313K) -

ジャーナル フリーThe optimum condition, obtained in the previous paper (part III) on the polymerization of monomeric CH2CHCOOH in open weighing bottle with redox (Na2S2O3-H2O2) catalyst, is tested on the polymerization on the viscose staple fabric.
The following results are obtained:
1. The yields of polymer are somewhat lower than the case of open weighing bottle, but 70_??_ per cent. yields are obtained.
2. Adequate values of Na2S203 are similar in both cases.
3. Lower yielde of polymer are obtained when concentration of monomeric are halved, especially when a small quantity of Na2S203 is used, yields of polymer are notably diminished.抄録全体を表示PDF形式でダウンロード (343K) -

ジャーナル フリーThe authors measured both the physical properties (such as crease recovery, imbibition value, elastic recovery) and the repeated-soaping effect on those physical properties and on nitrogen content of the treated fabrics, in order to investigate how the mechanism of crease recovery of the viscose rayon fabrics treated with Sumitex resin 901 (Dimethylol ethylene urea) is. The results obtained are summarized as follows.
1) The mutual relations of physical properties showed an intermediate value of the fabrics treated with formaldehyde and dimethylol urea.
2) Nitrogen content and crease recovery of the treated fabrics were distinctry reduced, while little change was observed on elastic recovery and imbibition value by 1_??_2 times of soaping.
3) Compared with dimethylol urea treatment, the physical properties and nitrogen content of the fabrics are stable for soaping.
From these results, crease recovery of the fabrics treated with Sumitex resin 901 is presumably affected by the formation of cross linkage between cellulose molecule and resin formed within the fiber.抄録全体を表示PDF形式でダウンロード (375K) -
