纯棉织物的醚化2D树脂成衣免烫整理

为探索醚化2D树脂对纯棉织物抗皱整理的可行性和最佳工艺设置,设计正交试验探究醚化2D树脂、催化剂、保护剂、柔软剂在成衣免烫技术中的应用工艺,确定最佳工艺为醚化2D树脂F-AP质量浓度150 g/L、催化剂FM质量浓度40 g/L、保护剂HDP质量浓度35 g/L、柔软剂NUP质量浓度15 g/L。应用SPSS统计分析软件对4种助剂对棉织物的抗皱整理效果做显著性检验,结果表明:相对另外3种助剂,醚化2D树脂对棉织物的抗皱整理效果影响最为显著。重点分析了醚化2D树脂对整理后织物性能的影响,发现醚化2D树脂质量浓度超过160 g/L时,棉纤维与树脂的反应呈现饱和,使棉织物折皱回复角和断裂强力变化趋缓,过多的树脂残留使纱线间的摩擦力增加,对织物抗撕破起负效果。     

水性聚氨酯在全棉织物免烫整理中的应用

采用单因素变量法研究常见的8种水性聚氨酯在醚化2D树脂整理体系中对棉织物免烫整理效果和强力的影响,并讨论强力保护剂在醚化2D树脂和水性聚氨酯复配整理中对棉织物折皱回复性能和强力保留效果的影响。结果表明:水性聚氨酯加入醚化2D树脂整理体系后,棉织物折皱回复性能、强力保留率均有不同程度的增加,其中水性聚氨酯3458整理棉织物折皱回复角最高可达275.00°,强力保留率提升12.35%;水性聚氨酯6222整理棉织物强力保留率高达69.52%,折皱回复角达到243.75°。强力保护剂可提高免烫整理后棉织物的强力保留率,但过量的保护剂会使织物折皱回复性能下降。在醚化2D树脂质量浓度为100 g/L,水性聚氨酯3458质量浓度为40 g/L,强力保护剂质量浓度为35 g/L时,织物免烫效果最佳,折皱回复角高达271.25°,强力保留率高达65.12%。     

甲醇醚化2D树脂的合成及应用

为降低2D树脂中的游离甲醛量和整理织物的甲醛释放量,采用两步法合成2D树脂,再用甲醇对其进行醚化改性。优化的醚化2D树脂合成工艺为:n(甲醇)∶n(2D)=3.5∶1.0,催化剂1.5%,甲醛捕捉剂5%,反应p H值3.0,70℃反应4.0 h。用其整理的织物甲醛释放量为44.29 mg/kg,折皱回复角约为224.92°,撕破强力保留率为48.85%。     

纺织专利信息（Ⅱ）

本发明公开了一种抗皱整理强力保护剂，包括50～120g／L的改性2D树脂、5～30g／L的催化剂、10～50g／L的柔软剂、1～3g／L的渗透剂、40～200g／L的聚乙二醇。用该制剂整理织物，可以得到优异的抗皱性能，织物的弹性、强力保留率、染色K／S值等都得到大幅度的改善。另外，使用该强力保护剂可以使整理工艺中的焙烘温度由原来的150℃大幅度降低至120℃，可以降低生产中的能耗。     

牛仔织物压皱树脂整理

讨论了牛仔压皱树脂整理中,复配催化剂种类与配比、增硬剂和强力保护剂用量对压皱效果、强力损失和色变的影响。优化后的牛仔压皱树脂整理处方为:2D树脂用量70 g/L,增硬剂20 g/L,强力保护剂TF-65215 g/L,渗透剂JFC 2 g/L。整理的牛仔布压皱效果好,强力损失较小,色变较小。     

棉子糖基无甲醛亲水性免烫整理剂制备及应用

为解决染整行业常用抗皱整理剂整理棉织物甲醛释放、亲水性降低问题，通过TEMPO-NaIO4选择性氧化体系对棉子糖进行两步氧化，制备一种新型的无甲醛亲水性抗皱整理剂——棉子糖多醛酸整理剂（简称openRa）。采用盐酸羟胺-甲基橙滴定法测定其醛基含量，并利用FTIR、1H NMR表征了openRa分子结构；优化openRa对棉织物抗皱整理的最佳整理工艺，并对比分析openRa在提高织物抗皱效果和亲水性能的优势。结果表明：openRa整理织物的最佳工艺为：openRa的浓度为100～150 g/L,pH值为4.0,SHP∶MgCl2=8∶12,150℃焙烘3 min和180℃焙烘2 min。与丁烷四羧酸、柠檬酸、醚化2D树脂和戊二醛等常规整理剂比较，经过openRa整理后，折皱回复角达到了261.5°、白度为61.5%，强力保留率≥65.0%，同时整理后织物的润湿时间≤2 s。     

甲醛捕捉剂在棉色织物免烫整理中的应用

为降低免熨整理后棉色织物上的甲醛释放量,选择4种甲醛捕捉剂对2D树脂整理后的织物进行处理,探讨了甲醛捕捉剂种类、用量对甲醛残留含量、DP值以及强力的影响.结果显示,选用SD-306C捕捉剂,其质量浓度为60 g/L时具有较好的甲醛捕捉性能;甲醛捕捉工艺以皂煮+甲醛捕捉剂处理最为有效.此外,甲醛含量测试方法以水萃取法测试值较为稳定.     

纯棉织物的免烫整理工艺优化

采用不同的免烫树脂对纯棉织物进行整理,以平整度、撕破强力、拉伸强力、甲醛含量、折皱回复角等指标来表征整理织物的免烫性能。优化的整理工艺为:树脂FEL 100 g/L,催化剂20 g/L,强力保护剂20 g/L,柔软剂30 g/L,160℃焙烘2 min。整理后织物DP等级达3.2级,断裂强力保留率达到80%。     

纯棉织物免烫整理工艺的优化

对纯棉染色纱卡织物进行免烫树脂整理.以免烫等级、断裂强力保留率、撕破强力提升率为指标对整理剂、催化剂和纤维保护剂进行筛选,并对整理工艺进行优化.优化工艺为:PCR-2树脂80 g/L,纤维保护剂PE-208 20 g/L,催化剂F-M 30 g/L,JFC 2 g/L,160℃焙烘3 min.经测试,产品DP达到3.5级.此外,纤维保护剂PE-208对整理织物的撕破强力有显著的提升效果.     

醚化2D树脂潮态交联工艺

采用醚化2D树脂，以MgCl2·6H2O为催化剂，在室温条件下对棉织物进行潮态交联。研究了树脂用量、催化剂用量、pH值及堆置时间等因素对整理织物折皱回复角、断裂强力保留率、白度和甲醛释放量的影响。优化的醚化2D树脂的潮态交联工艺为：醚化2D树脂用量200g／L，MgCl2·6H2O用量为24％（相对树脂用量），pH值2，堆置时间24h。结果表明，整理后棉织物的折皱回复角有所改善，强力保留率在60％，甲醛释放量小于75mg／kg。     

Review of techniques to manufacture micro-hydrogel particles for the food industry and their applications

Microgels are ‘soft’ microscopic cross-linked polymeric particles that are being increasingly exploited in a variety of industries for rheology control, encapsulation and targeted delivery. They are valued because of the ability to tune their functionality to address specific applications in oil recovery, coatings, drug delivery, cosmetics, personal care and foods. Food microgels are typically biopolymer hydrogels in the form of microspheres, nanospheres (also called nanogels), spheroids and fibres. The utilisation of engineered microgels in foods has so far been limited, despite their great potential to address several needs in the food industry, including: satiety control, encapsulation of phytonutrients and prebiotics, texture control for healthier food formulations (e.g. reduced fat products), and targeting delivery to specific areas in the digestive tract. We review the scientific and patent literature on the utilisation and manufacturing methods for producing microgels with an emphasis on micro-hydrogels for food applications.     

12—A CRITIQUE OF SOME HYPOTHESES RELATING TO THE HETEROGENEITY OF THE HIGH-SULPHUR PROTEINS OF WOOL

Joubert and Burns prepared a large number of fractions from the high-sulphur proteins of wool and estimated their molecular weights and amino-acid compositions. Their data have been re-examined in order to look for statistically significant interrelations between amino acids and between the proportion of various amino acids and molecular weight. Statistical analysis of the data is also used to examine the credibility of some hypotheses concerning the mechanism of keratin biosynthesis and to provide further evidence for the existence of families of proteins within the high-sulphur fractions of wool.

Contamination of animal feed and food from animal origin with mineral oil hydrocarbons

Oils and fats used for the production of animal feed can become contaminated with mineral oil material originating from gas oils (C₁₈-C₃₅) or synthetic oils (poly alpha olefins, C₂₅ to beyond C₄₅). An important cause is assumed to be the discharge of waste oils, such as motor oil and hydraulic oils. Mineral oil material was analysed by on-line LC-GC-FID directly in the fat or in a raw extract from animal feed or foodstuffs. In Switzerland in summer/autumn 1999 concentrations in oils and fats for feed production were often found to be between 100 and 1000mg/kg. In the feeds, the average concentration was around 100mg/kg with values ranging up to a maximum of 1000mg/kg; few samples were free of contamination. In animal body fat, the average concentration determined in summer 1999 was 25mg/kg, with a maximum of 150mg/kg, although in samples from December 1999, contamination was substantially lower. In the fat phase of eggs, the average concentration was 30mg/kg, with a maximum of 80mg/kg. Paraffin oil is used for feed production, which may account for part of the contamination problem (e.g. eggs).
