As fragrances are volatile, only microencapsulated aroma can stay on textiles for long periods, since capsules greatly reduce the aroma evaporation rate. An aroma finished textile has to be washable. Therefore, aroma capsules finished on textiles should not only last for long time statically but also withstand harsh washing conditions. Due to low affinity between encapsulated aroma and fabric, a fixing agent must be applied with the capsules; the fabric has to undergo a curing treatment to make the agent fix these capsules. However, the curing process is usually a high-temperature thermal procedure that causes aroma loss from capsules by quick evaporation. Thus, fragrant durability on fabrics can vary significantly with different fixing agents and curing processes. Three fixing agents, three kinds of thermal curing equipment, and various curing conditions were investigated. By analysing properties of the fixing agents, heat transfer characteristics of the curing apparatus, and delivered energies in the curing conditions, a washing durable aroma capsule finishing process for cotton fabric was developed.}, number={2}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Li, Shiqi and Lewis, Joy E. and Stewart, Neil M. and Qian, Lei and Boyter, Henry}, year={2008}, pages={177–183} } @article{qian_li_2006, title={Dyeing behavior of melt spun acrylic fiber with basic dyes}, volume={6}, number={2}, journal={AATCC Review}, author={Qian, L. and Li, S.}, year={2006}, pages={44–48} } @inproceedings{li_xu_hinks_shamey_2006, title={Understanding and predicting shade variation based on fiber fineness and fabric structure}, booktitle={American Association of Textile Chemists and Colorists, International Conference & Exhibition (AATCC-ICE) 2006}, publisher={American Association of Textile Chemists and Colorists}, author={Li, S.-Q. and Xu, C.-H. and Hinks, D. and Shamey, R.}, year={2006} } @article{li_boyter_2005, title={Washfastness improvement for heavy shade microdenier nylon 6,6 fabric}, volume={5}, number={8}, journal={AATCC Review}, author={Li, S.

Adding CC to the crosslinkers improves acid dye uptake only slightly more than using the crosslinking agent alone. A disadvantage of cc is that the loose dye stains onto white unprinted areas during laundering. The main function of crosslinkers is not only to chemically link the dye to cellulose, but also to form a crosslinked network to block the entrance of the fiber pores where dye molecules have previously penetrated. }, number={9}, journal={Textile Research Journal}, author={Yang, Y. and Li, S.}, year={2003}, pages={809–814} } @article{yang_li_stewart_2003, title={One-step inkjet printing and durable press finishing}, volume={3}, number={3}, journal={AATCC Review}, author={Yang, Y. and Li, S. and Stewart, N.}, year={2003}, pages={29–31} } @article{yang_li_brown_casey_2002, title={Dyeing of PTT/PET blends}, volume={2}, number={8}, journal={AATCC Review}, author={Yang, Y. and Li, S. and Brown, H. and Casey, P.}, year={2002}, pages={54–59} } @article{yang_brown_li_2002, title={Some sorption characteristics of poly(trimethylene terephthalate) with disperse dyes}, volume={86}, ISSN={["0021-8995"]}, DOI={10.1002/app.10953}, abstractNote={AbstractSorption characteristics, such as sorption kinetics and isotherms, relation between dye sorption and shade development of poly(trimethylene terephthalate) (PTT) and their comparison with poly(ethylene terephthalate) (PET), were reported.

We found that PMA and TPMA were less effective than 1,2,3,4-butanetetracarboxylic acid (BTCA) due to the low mobility of the anhydride intermediates to access the cellulosic hydroxyl during a curing process. We found that the hydroxyl of citric acid (CA) hinders its esterification with cotton cellulose, and so is less effective than 1,2,3-propanetricar boxylic acid as a crosslinking agent for cotton. We also found that CA esterifies the anhydride intermediate of PMA or TPMA on the cotton fabric formed under curing con ditions. In this research, we observed a synergistic effect by combining PMA or TPMA with CA as co-crosslinking agents for cotton fabrics. The combination of TPMA/CA is more effective than the PMA/CA combination for imparting wrinkle resistance to the finished cotton fabrics. Cottons finished with the TPMA/CA combination show superior durable press performance, good laundering durability, and high fabric strength retention. The superior performance and cost effectiveness of this new finishing system makes it feasible as a replacement for formaldehyde-based durable press finishes. }, number={6}, journal={TEXTILE RESEARCH JOURNAL}, author={Yang, CQ and Xu, L and Li, SQ and Jaing, YQ}, year={1998}, month={Jun}, pages={457–464} } @inproceedings{yang_li_1998, title={Single bath one step dyeing of polyester/cotton with disperse/reactive dyes}, booktitle={Book of papers: 1998 international conference & exhibition, September 22-25, Philadelphia Marriott, Philadelphia, Pa.}, publisher={Research Triangle Park, N.C.: American Association of Textile Chemists and Colorists}, author={Yang, Y. and Li, S.}, year={1998}, pages={414–425} } @article{li_white_tincher_1997, title={Analysis for dyes over a wide concentration range for possible application to online measurement}, volume={19}, number={12}, journal={Textile Chemist and Colorist}, author={Li, S. and White, B. and Tincher, W.

Lyotropic numbers and the salt effect on water‐structure changes are considered to describe their influence on the physical interactions between the sorbate and the sorbent. It is found that some electrolytes, such as sulfates and phosphates, can increase the sorption of some negatively charged ions (e.g., acid dyes) on positively charged polyamide it salt concentration is high (e.g., > 0.5 M), after the initial decrease of ion sorption at a low salt concentration range. This result is difficult to explain by the model that treats all interactions other than ionic interaction as a constant.
