The Technology Design Of Alkali-minimization Treatment For C-type Hollow Polyester Filament

With the consumers’ interests turning to wearing comfort and health care, natural fibers andits blended fabrics are more popular again than the polyester and other chemical fibers which areeasily cared. Natural fiber, which is full feeling and good health care, is making a challenge for thepolyester. So the hollow polyester fiber is starting a new age for chemical fibers. C-type HollowPolyester, as a new product, will certainly attract much attention. The technology designed in thispaper has a significant meaning in development of new functional products and improvementproduct competitiveness for the company, and confirms the trends of polyester’s developing.The paper is mainly about the process design of alkali-minimization treatment for C-typehollow polyester filament. And some basic performances of the C-type hollow polyester filamentare tested. The main contents are as follows:Firstly, the processing equipment used for alkali-minimization treatment and the influencefactors is selected out according to some reference of the related literature and company’s situation.And then the experiment steps are prepared well. Before the experiment, the feasibility analysis isindispensable.Secondly, experimental scheme of alkali-minimization treatment for C-type hollow polyesterfilament is designed according to the result of the feasibility analysis. And then the experimentresults are summarized. Also some basic performances of the C-type hollow polyester filament aretest. At last the preliminary process which is satisfied by consumers is figured out with theanalysis of data.Thirdly, the feasibility analysis is made based on three processing factors that are the lyeconcentration, temperature and holding time, with the preliminary process.Fourthly, the orthogonal experiment is designed with the three processing factors accordingto the result of the feasibility analysis. And the optimal processing scheme is picked out from theresults. Also the optimal processing scheme is numerical corrected referring to the processingexperience. The experiments are made with the two kinds of process. Also the basic performancesof the C-type hollow polyester filament are tested.Fifthly, the optimized processing experiment is made with the corrected processing scheme.And the product inspection report, which is given by the consumer, is ok. Finally, the paper getsthe best technology of alkali-minimization treatment for C-type hollow polyester filament.
