JOURNAL FREE ACCESSThis paper aimed at clarifying the relations between bonding conditions of fusible interlinings for men's dress shirts collar which was called ‘top fusing’ and their end-use performances. Factors and levels in the design of experiment were as follows;
A: Bonding temperature…A1; 140°C, A2; 165°C, A3; 190°C.
B: Combination of angles of bonded fusible interlinings to the warp direction of face babric…B1; 45°-0°, B2; 45°-90°, B3; 45°-135°, B4; 30°-150°
Results obtained were as follows:
(1) The contributing ratio of A to the shrinkage percentage at pressing for bonding was extremely smaller than that of B.
(2) The shrinking behavior of warp direction of the interlinings affected the shrinkage of face fabric.
(3) The contributing ratio of A to the peeling strength was 56-72% and there were significant differences among the levels of factor A.
(4) The optimal bonding temperature were estimated by the orthogonal polynomials.
(5) The bending rigidity and the bending hysteresis increased with rising the bonding temperature.View full abstractDownload PDF (717K) -
Part 3: Effect of Chelating Agents to Cloths dyed with Metal Complex Dyes in Bleaching by Sodium PercabonateRitsuko Oura, Seibe Yoshikawa1983 Volume 24 Issue 10 Pages 446-451

JOURNAL FREE ACCESSIt has been found that the tensile strength of the cloths dyed with metal complex dyes often decreases with the repeated bleaching. In this paper, using some chelating agents (EDTA, NTA, IDA, etc.), an attempt was made to prevent this degradation by blocking the metal in dyes, resulting in the decrease of the catalytic decomposition rate of bleaching agent (sodium percarbonate) . The results were summarized as follows:
(1) When sodium percarbonate was added to the solution of metal complex dyes pretreated with these chelating agents, the decolouring of this solution was little observed. But if the solution of the dyes did not treated with these agents, remarkable decolouring was observed.
(2) When the dyed cloths were pretreated with these chelating agents and repeatedly bleached by sodium percarbonate, the tensile strength of he cloths hardly decreased.
(3) Colour difference (ΔE) of the dyed cloths treated with EDTA increased with repeated bleaching, whereas, in the case of IDA, 4E was little observed.
Considering these experimental results, it was shown that IDA was most effective chelating agents to prevent the degradation of the dyed cloths.View full abstractDownload PDF (678K) -

JOURNAL FREE ACCESSPolymeric films are often employed as packing materials to prevent the contamination of formaldehyde (HCHO) to a fabric. The effects of chemical structure and super-structure of polymeric films on the anticontamination of formaldehyde to a fabric were examined for the variouskinds of polymeric films. For this purpose, two kinds of measurements were carried out. One is a bag method which enables to measure the contamination of HCHO to a wool fabric packed in polymeric films. Another is a cup method, devised for the determination of the permeability of HCHO through a polymeric films placed on a brim of the cup by measuring the absorption of HCHO into water in the cup.
The results obtained are as follows:
(1) The amount of contamination to the wool fabrics increased in proportional to an exposure time.
(2) Among the polymeric films used in this study, the PVDC-coated OPP film was most effective to anticontamination of HCHO.
(3) The permeability of HCHO was satisfactorily determined by the cup method, but the effect of the moisture content must be taken into acount.
(4) The permeability coefficient (P) of HCHO for the hydrophobic polymeric films are satisfactorily estimated from the value of“Permachor” (π) by the following equation:
P=1.86×10-7e-0.111π
(5) The permeability coefficient of HCHO was strongly dependent upon the moisture content in a film for every kinds of hydrophilic polymers.
(6) The values of the permeability determined by the cup method were always higher than those by the bag method. However, the both methods gave the same sequence order in permeabilities for the polymeric films used in this study.View full abstractDownload PDF (859K) -

JOURNAL FREE ACCESSThe warmth retention (H) of composite fabrics has been investigated by the constant temperature method. Interlinings including fusible interlinings on the market and face fabrics have been used as constituent fabrics of the composite fabric. The results obtained were as follows:
(1) The adhesive resin on the surface of face fabrics laminated with fusible interlinings seems to affect the value H.
(2) The value H of composite fabrics can almost be explained by the theoretical equation. However, careful consideration has shown that the measured value deviates, depending on the surface condition of the face fabrics, from the values predicted by the theoretical equation.
(3) For the same constituent composite fabrics, the H of the adhesive fabrics is lower than that of piled up fabrics. The measured H of the adhesive fabric is remarkably lower than theoretical one. It would result from the fact that the adhesion of the fabrics remarkably reduces the air content between boundary region between two fabrics.View full abstractDownload PDF (2886K)
