Abstract
The paper articulated the relevance of the Philippine Textile Research Insitute (PTRI), through the PTRI testing Laboratory (PTL), to the Small and Medium Enterprise (SMEs) and large companies as they face the challenge and threats of globalization. The testing services provided by PTL translated to the companies' quality assurance, which is instrumental to gain wider market acceptance, even without maintaining costly testing laboratory of their own, that redounds to saving in the companies' operating costs.
Mulberry Sapling Development as Affected by Variety and Planting Method
Fermin O. Bayeng, Jr. and Adelfa M. Basaen
Abstract
The study was conducted to compare the effect of horizontal and vertical planting methods for cutting of mulberry varieties Kanva, Kingson, S54 and Thailand on the monthly growth height, percentage cutting survival, and number of sapling developed. Results revealed that in vertical and horizontal planting methods the Thailand variety yielded significant difference in monthly growth height, percentage cutting survival and number of saplings developed over varieties Kanva, Kingson and S54. Kingson proved to perform better in horizontal planting method as compared to vertical. Vertical planting method showed more advantages than horizontal for Kanva and S54.
Double Sley Picker for Upright Handloom
Caridad M. Cuchon and Jovita A. Hayin
Abstract
The Philippine handloom weaving industry, which falls under the micro, small and medium enterprises (MSMEs), has reminded a significant contributor in providing economic activities in the remote and rural areas of the country. Handloom woven products are among the non-traditional export contributors of the country's foreign earnings. Today, handloom weaving still stands to be a major occupation not only of the indigenous people but also of the rural folks.
Textile Potential of Different Banana Fiber Varieties
Marites S. de Leon
Abstract
Six virieties of banana (Musa) plant namely Bongolan, Lakatan, Pakil, Saba, Siksik and Tordan were used in this study. The decorticated banana fibers exhibited gum content ranging from 40%-48%, tensile strength of 23-26 kgf-m/g and fineness of 67-93 denier.
The decorticated fibers were subjected to degumming treatment to render them spinnable into yarns. The residual gum content, tensile strength and fineness of the degummed fibers were compared to the previously studied Cavendish variety which served as the standard. All the varieties showed similar behavior towards degumming with about 80% of the gums effectively removed. Marked reduction in the tensile strength was observed but the values were still within the acceptable range for textile processing. While improvement in the fiber fineness was observed as evidence by 8%-30% reduction, all the varieties were still coarser compared to Cavendish. Summarizing the results, the potential of the banana fiber varieties for textile processing can be ranked from high to low as follows: Saba, Lakatan, Bongolon, Pakil, Saksik, Tordan.

Abstract
This short term study aimed to evaluate the formation of mildew to treated and untreated tikiw (Rhynchospora corymbosa), bangkuang (Actinoscisrpus grossus) and raffia (Corypha eleta) under normal environmental conditions. The study also evaluated the effect of washing and drying and the applicability and effectiveness of two commercial mildewcides on the fibers. The mildewcide treated fiber showed no signs of mildew growth, while untreated tikiw fibers were 40-80% and bangkuang and raffia were 1-3% covered with mildew. The application of mildewcides was effective in preventing the growth of mildew.
Phenotypic Characters of Silkworm Purelines LAT 2, LAT 71 and ST2
Alfrieta B. Olayo, Adelfa M. Basaen, Catherine M. Kimbongan and Evelyn A. Sicat
Abstract
This study was conducted to establish the phenotypic characters of silkworm purelines Lat 2, Lat 71 and ST2 that were evolved from foreign hybrids Japanese A, Guang Nong 3 and Su Tung, respectively. This silkworm purelines were reared five times between the period March 2000 - April 2002 to observe, verify and record distinguishable external characters that are used to describe and identify silkworm breeds. These characters shall serve as basis and guide for future silkworm breeding studies aside from providing additional database of silkworm genetic resources in the Philippine Textile Research Institute's germplasm.
