The research was an objective to study the weaving proves in the central of Thailand. IT was focused on problem study and design consumption by special loom as jacquard for improving the weaving techniques. This research not only data analysis ofr jacquard production but also transfer knowledge as economic efficiency product by workshop. This study was an experimental development research by purposive sampling. The information were surveying from ๓ groups. The first was ๒๕ people what using native woven in north central of Thailand as Nern-kham woven cluster at Nern-kham district Chainat province. The second was ๒๕ people what using flying shuttle woven from Wat nam Tao in Ma-ha Rat district Ayutthaya province. And ๕๐ people what using produced loom. The results were evaluated in jacquard satisfaction as reduced time production by using ๑๒๐ heddles ease of jacquard setting up that was delicate and versatile styles on native woven such as Yok-Dok Yok-kit Teen-jok Praw-wa and the other native styles. The heddles tool was Rectangular and C-type steel whatever it was greater durability material. The additional this product had the returnable storage cards that they were controlled by cylinder. The working area was individual adjustable. However the combination of this product into the traditional loom weaving must be controlled by specialist. This produced machine was ease movement and reduced torn warp yarns. The fabric was rolled by hand lever to turn the both side together. The heddle was raised by foot lever in rhythmic weaving. The produced jacquard was a similar production cost as the same product but it had better efficiency and reasonable price. It was suitable for new weaver thus had a background in basis weaving for making the high efficiency production and good quality product. Thus the machine had an axil and gear for reed locked and hit regularly width fabric. The summarize research concerned with process technique weaving process. The main was jacquard system of heddle lift system. It promoted the development knowledge for semi-automatic loom weaving thus motor and electricity combination. Moreover the design of jacquard for loom weaving was basement knowledge of developing the new equipment tools pattern for textile product in ecology economical furthermore.

The purpose of this research was to develop new mixed fiber from waste cocoon and other plant fibers. It was found that waste cocoon has qualitative properties to produce new mixed fiber when mixed with five kinds of plant fibers namely cotton yarn linen yarn pineapple yarn ramie yarn and hemp yarn. The processes included boiling waste cocoon in wetting agent water and Sodium Carbonate for 30 minutes at 90 ºC and dehydrating it. After that short cocoon yarn was obtained. Then mix it with the five kinds of plant fibers with the ratio of 50:50 in carding at silk card and undergo mixing and spinning process. Qualitative test result of new mixed fiber from waste cocoon used as weft yarn and five kinds of plant fibers used as warp yarn in industrial weaving showed that fiber from waste cocoon mixed with hemp yarn has the best breaking strength of 194 CN/tex followed by waste cocoon mixed with ramie yarn of 149 CN/tex waste cocoon mixed with linen yarn of 146 CN/tex waste cocoon mixed with pineapple yarn of 145 CN/tex and waste cocoon mixed with cotton yarn of 143 CN/tex. Meanwhile fiber from waste cocoon mixed with heft yarn has the best mean elongation of 2.30 cm followed by waste cocoon mixed with cotton yarn of 2.32 cm waste cocoon mixed with ramie yarn of 2.77 cm waste cocoon mixed with linen yarn of 3.42 cm. and waste cocoon mixed with pineapple yarn of 3.43 cm. Thus the research results indicated that fiber from waste cocoon mixed with hemp yarn is good for producing home textile as it has the highest breaking strength while fiber from waste cocoon mixed with pineapple yarn is good for producing clothes.
