用BTCA/ACT复合体系改善棉织物防皱整理后的强力

针对单独使用BTCA或ACT作为防皱整理剂存在的不足，提出用BTCA和ACT组成棉织物的复合防故整理体系。通过实验得出，ACT在该复合体系中不仅可通过其热分解的产物与纤维素交联，催化BTCA与纤维素交联，还能调节整理液的pH值，可改善处理后织物的强力。     

The Effect of Variation of the Isocyanate Content on the Refractometric Determination of the Concentration in Polyurethane Treatment Baths

A knot not previously used in the textile industry, the double-harness bend, is described and its performance in torque-unbalanced weaving yarn reported.

It is shown that the knot can be tied in three distinct ways, which behave differently under stress when tied in torque-unbalanced yarn. The performance of the knots is compared with that of the fisherman's knot, and it is shown that the best of the double-harness bends is likely to offer improved weaving.     

聚马来酸的制备及其在棉织物免烫整理中的应用

以马来酸为单体,过硫酸钾为引发剂,合成了聚马来酸,并将其用于棉织物的免烫整理,同时探讨了最佳合成及应用工艺.通过对棉织物整理后的测试结果表明,整理后织物回复角为270°左右,纬强60%左右,5次水洗,回复角仍为260°左右,聚马来酸整理与BTCA整理效果相当.     

棉织物的丝胶整理及其相关性能研究

为利用丝胶独特的性能改善棉织物的服用性能,以BTCA为交联剂,采用轧烘焙的方法用丝胶对纯棉织物进行整理。经傅里叶变换红外光谱(FT-IR)和扫描电镜(SEM)分析,证明在高温条件下,丝胶交联固着在织物表面。可用柠檬酸钠和酒石酸钠混合代替次亚磷酸钠作为BTCA的催化剂。整理后棉织物的吸湿、放湿及保温性能有明显提高。     

纯棉细纱卡无甲醛免烫整理工艺探讨

本文通过平行试验和正交试验法优化了丁烷四羧酸（BTCA）与自制无甲醛复合催化剂用于纯棉细纱卡的免烫整理工艺。并与低甲醛整理剂整理效果进行了试验对比,BTCA与自制复合催化剂整理后织物湿折皱回复角达226．4°,水洗后DP级达3～3．5级,泛黄率及撕破强力损伤率低于低甲醛整理剂,干态弹性回复性能与低甲醛整理荆整理效果基本相同。     

用BTCA对亚麻织物无甲醛免烫整理的工艺条件

为了实现无甲醛整理,采用BTCA剂对亚麻织物进行免烫处理。通过探讨整理过程中各因素对织物折皱回复角和强力保留率的影响,运用正交分析优选出整理剂配方及工艺条件。在BTCA80g/L、SHP60g/L、S 96020g/L、预烘80℃2min、焙烘150℃3min条件下进行免烫整理,亚麻织物的抗皱性能可得到明显的改善,且强力保留率较高。     

Photocatalytic functional cotton fabrics containing benzophenone chromophoric groups

In preparation of self‐decontamination clothing materials in high reactivities against toxic agents, photoactive benzophenone chromophoric groups were incorporated into cotton fabrics. The cotton fabrics were treated by using 4‐hydroxybenzophenone as a reagent, 1,2,3,4,‐butanetetra carboxylic acid (BTCA) as a crosslinker, and sodium hypophosphite as a catalyst. The fabric treatment was conducted by a pad‐dry‐cure method. The benzophenone chromophoric group incorporated cotton fabrics were characterized by FTIR, SEM, TGA, and so on. The results confirmed the expected structures of the benzophenone chromophoric group modified and BTCA crosslinked cotton fabrics. The treated cotton fabrics demonstrated radical reactivities and antibacterial activity under UV irradiation. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007     

Antibacterial properties of silk fabric treated with Aloe Vera and silver nanoparticles

Silk is one of the important textile fibres used in apparel application. Since it is hygroscopic proteinous fibre, it is affected by microbes during usage and storage. Hence, antimicrobial treatment is desired to contain with this problem. Antimicrobial treatment is done using natural and synthetic agents. Nanoparticles have been added as antimicrobial agent for the application. In the present work, composite treatment of silk with Aloe Vera– a natural product and silver nanoparticles is done through crosslinking of 1,2,3,4-butane tetra carboxylic acid (BTCA) with silk in the presence of sodium hypophosphite (SHP). Effect of varying the concentration of BTCA, Aloe Vera and silver nanoparticles has been investigated. Untreated and treated silk fabrics have been characterized by FTIR, SEM and XRD to elucidate the effect of the treatment in terms of binding of Aloe Vera and silver nanoparticles, morphological changes and degree of crystallinity. Mechanical properties have been evaluated and analysed to illustrate the effect of the treatment. Further, the antimicrobial properties of the treated samples were evaluated against S. aureus (gram positive) and K. pneumoniae (gram negative) bacteria and the antimicrobial activity is found to be excellent. In order to assess the durability of the treatment, dry-cleaning has been done and subsequently antimicrobial properties have been assessed. Treated silk fabric samples after dry-cleaning upto 5 cycles exhibited satisfactory antimicrobial activity indicating that the treatment is durable in all the recipes. It is inferred that Aloe Vera chemically binds with silk through BTCA crosslinking while silver nanoparticles get adhesively bound or entrapped in the fibre matrix resulting in durable antimicrobial activity.     

Investigation into the removal of a formaldehyde-free easy care cross-linking agent from cotton and the potential for subsequent regeneration of lyocell-type fibres

1,2,3,4-Butane tetracarboxylic acid (BTCA)-treated cotton fabrics were immersed in alkali for increasing time periods and the effectiveness of alkali in removing the cross-linking agent was investigated by surface (X-ray photoelectron spectroscopy, XPS) analysis, attenuated total reflectance Fourier transform infrared spectroscopy and solubility in specific solvents. The cellulose yield after the chemical ‘stripping’ processes was established and the effect of the alkali treatments on the degree of polymerization of the resultant cellulose determined. Surface analyses and solubility tests suggested that the alkali alone could successfully remove the BTCA from the crease resist-treated cotton fabric and produced a commercially viable yield of cellulose.
