Bicomponent fiber is a specific type of synthetic fibers with two different properties of polymers joined together in the same filament during spinning process. Bicomponent fibers have distinctive properties from monocomponent fibers. The properties of fibers are outcomes of type of cross section properties of composed polymers fiber spinning process condition and after-treatment process. The primary applications of bicomponent fibers are self-crimping (or self-bulkiness) fibers thermal binder fibers microfibers and special property fibers which can be added into the shealth of fiber. The fiber processing types and applications of bicomponent fibers are summerised and stated in this paper.

Biodegradable polymer blend fibers were prepared by melt spinning technique. Poly(lactic acid) (PLA) and poly(butylene succinate) (PBS) were blended in a twin screw extruder at various contents of PBS at 0-50 wt%. PLA/PBS blends were melt spun using a single screw extruder equipped with multifilaments spinnerette. The effect of PBS contents on morphology thermal properties and mechanical performance of PLA/PBS blend fiber was investigated. SEM micrographs indicated that the addition of PBS at 10 wt% showed miscibility of PLA/PBS blends while the other contents of PBS exhibited phase separation of the blends. The incorporation of PBS affected on the declination of crystallinity in the blends. It can be noted that the addition of PBS could enhance the elasticity of PLA/PBS blend fibers.

This study aims to develop household textiles from Surin Batik silk with pattern of Ancient Khmer Art at Sikhoraphum Castle and to study customers’ satisfaction of household textiles. The population was 400 assessors within the age range of 20 - 50 years in Surin province. The research instrument was questionnaire. Data were statistically analyzed for Percentage Mean and Standard Deviation. Results showed that the majority of respondents were females with ages around 31 - 35 years old. Most of them were married and had income of 15000 – 25000 baht. Most got Bachelor’s degree and used to use household silk textile. Working clothe was the most purchased category. Most household textiles were purchased as souvenirs. Personal preference was the initial motivation for purchase decisions and utilization was the key factor for selecting a product. Regarding onsumers’ satisfaction in 3 types of household textiles from Mudmee Batik silk - cushion lamp and bed cloth – it was found that satisfaction in style pattern colour price and utilization were in similar high level. Cushion was the most purchased household textile. Peacock was the most favorite pattern and consistency of the pattern was the most important factor for purchasing.

The purpose of this research was to study the basic needs of hand-woven cotton fabric with natural dyes the Nan Mon Chae Son group in Lampang. The research instruments were interviewing and evaluation form. The sample were 100 people. The statistic of this research was percentage. The findings revealed that there were different kinds of hand-woven cotton fabric with natural dyes such as scarves bedspreads towels tissue boxes hats bags clothes and pieces of cloth. The design of a luggage storage of heat and hand-woven cotton fabric with natural dyes the Nan Mon Chae Son group divided to 5 groups 25 patterns. The design of mother bag was appropriate at 82% the design of children bag was appropriate at 80% The design of lady bag was the most appropriate at 90% the design of health bag was appropriate at 82% the design of travel bag was appropriate at 81%. The recommendation from evaluation group are as follows. It should make a new products (13 evaluator). It should use the leather for bag handles and decoration (3 evaluator) It should develop the light fastness of fabrics which made from hand weave and natural dye. (4 evaluator).

The objective of this research was to study the feasibility for producing the dry Dioscorea hispida powder as a thickener. The product was investigated in their properties the compatibility with dye and chemicals in print paste color appearance by indicated with color hue value the time durability storage the residual substance after washing treatment and the color fastness in washing and rubbing methods. The results shown the dry Dioscorea hispida powder was used as thickener that it was the good characteristic like the famous textile printing thickener as alginate. The dry Dioscorea hispida powder thickener was 10%w/w had the equivalent viscosity as 8%w/w alginate. It had 3 days stability storage and good compatibility for direct dye reactive dye acid dye and disperse dye print pastes. The color appearances were corresponding with owned hue in color index databases. The thickener was completely in washing process. And the washing and rubbing fastness were good to excellent.
