An efficient in vitro propagation of Samanea saman (rain tree) protocol has been successfully developed using nodal explants from a 20-year-old tree. Higher percentage (76 %) of explants produced up to five shoots per explant on Murashige and Skoog (MS) medium supplemented with 2 mg L-1 6-benzyladenine (BA), 0.1 mg L-1 gibberellic acid (GA3) and 100 mg L-1 casein hydrolysate after 3 weeks of culture. When explants were subcultured to fresh medium after harvesting first batch of shoots, more shoots could be generated (another eight shoots per explant). Shoot elongation was achieved (3 cm) when shoots were cultured on MS medium supplemented with 0.25 mg L-1 BA and 0.75 mg L-1 GA3. In vitro generated shoots rooted on MS medium fortified with 0.75 mg L-1 indole-3-butyric acid plus 0.1 % of activated charcoal. A higher percentage of explant response and shoots per explant were obtained on MS medium with BA and GA3. Each responsive nodal explant yields an average of 15 rooted plants within a period of 10 weeks. Rooted plantlets were successfully acclimatized in green house with a survival rate of 90 %. Micropropagated plants were tested for genetic stability using simple sequence repeats (SSR) markers. Use of the 12 high-resolution SSR markers revealed the exact same genetic profile between the mother tree (donor) and micropropagated plants, suggesting the genetic fidelity of our micropropagation protocol. The same protocol was also used successfully in propagating a ‘‘Golden Rain Tree’’ although response of explant and efficiency of propagation was much lower. This protocol will be useful for germplasm preservation/large scale production of true-to-type clones of desirable genotypes.

Cellulase has the ability to remove fuzz-fibres from cellulosic textiles, which endows fabric with a glabrous appearance and soft handle. In this paper, the combined uses of bio-polishing and reactive dyeing in one bath were carried out, aiming at shortening the treatment time and reducing the overall consumption of water and energy as well. The properties of cotton fabrics before and after the combined treatments were investigated, including the colour strength, colour fastnesses and tearing strength. The results indicated that the colour fixing agent of soda had noticeable inhibiting effects on cellulase activity. Meanwhile reactive dyes might react with cellulase proteins under alkaline conditions, resulting in decelerating influences on the dye-fibre covalent reactions. The acceptable one-bath process consisted of bio-polishing and dyeing of cotton in neutral solution, followed by dye fixation under alkaline conditions. Compared to polishing and dyeing in two baths, the one-bath method endowed fabric with a bit lower colour strength.

Celulaza ma zdolność do usuwania włosków zmechacenia z tekstyliów celulozowych, co pozwala na osiągnięcie gładkiej powierzchni o delikatnym chwycie. W pracy badano sumaryczny efekt biopolerowania i reaktywnego barwienia przeprowadzanych w jednej kąpieli. Metoda ta ma na celu skrócenie czasu obróbki i zredukowanie ogólnego zapotrzebowania na wodę i energię. Badano właściwości tkanin bawełnianych przed i po obróbce. Między innymi badano nasycenie kolorem, trwałość koloru i wytrzymałość na rozrywanie. Wyniki wskazują, że soda jako środek utrwalający kolor ma zauważalny wpływ na hamowanie działania celulazy. Porównując metodę równoczesnego polerowania i barwienia z metodą, gdzie obydwie obróbki stosowane są indywidualnie stwierdzono, że w metodzie równoczesnej obróbki uzyskuje się nieco niższe nasycenie koloru.

This research presented a novel method using 3D simulation methods to design customized garments for physically disabled people with scoliosis (PDPS). The proposed method is based on the virtual human model created from 3D scanning, permitting to simulate the consumer’s morphological shape with atypical physical deformations. Next, customized 2D and 3D virtual garment prototyping tools will be used to create products through interactions. The proposed 3D garment design method is based on the concept of knowledge-based design, using the design knowledge and process already applied to normal body shapes successfully. The characters of the PDPS and the relationship between human body and garment are considered in the prototyping process. As a visualized collaborative design process, the communication between designer and consumer is ensured, permitting to adapt the finished product to disabled people afflicted with severe scoliosis.

This paper presents a virtual design process for a tight-fitting garment pattern for adapter consumer garments, aimed at consumers with scoliosis. The design process proposed is based on a virtual human model created using a 3D scanner, allowing simulation of the morphological shape of an individual with atypical physical deformations. Customized 2D and 3D virtual garment prototyping tools are used in combination to create products through interactions between the consumer, designer and pattern maker. After following an interactive sequence: Scanning – Design – Display – Evaluation – Adjustment, a final design solution acceptable to both the designer and consumer can be obtained. Through this process, traditional 2D garment design knowledge, especially design rules influenced by the fabric information, is fully utilized to support the design process proposed. Using the knowledge based collaborative design process, design satisfaction can be largely improved.

W artykule przedstawiono wirtualny proces projektowania wzoru odzieży dla osób ze skoliozą. Zaproponowany projekt jest oparty na wirtualnym modelu ciała człowieka stworzonym przy użyciu skanera 3D, umożliwiającego symulację morfologicznego kształtu ciała osoby o nietypowych deformacjach fizycznych. Po wykonaniu sekwencji interaktywnej: skanowanie – projekt – wyświetlacz – ocena – dostosowanie, można uzyskać ostateczne rozwiązanie projektowe akceptowalne zarówno dla projektanta, jak i dla konsumentów. W tym procesie tradycyjna wiedza z zakresu zasad projektowania odzieży 2D jest w pełni wykorzystywana w celu wspierania zaproponowanego procesu projektowania. Korzystając z kombinacji obu systemów 2D i 3D można w znacznym stopniu poprawić jakość otrzymanego projektu. Udane rozwiązania projektowe można zintegrować z bazą wiedzy o projektowaniu mody, aby tworzyć nowe zasady projektowania i rozszerzać profesjonalną wiedzę dotyczącą projektowania.
