Kinetic model of photoinduced polymerization of phenyl glycidyl ether monomer

A kinetic model for the photoinduced polymerization of phenyl glycidyl ether with a sulphonium salt as photoinitiator obtained from Union Carbide is presented. The kinetics of the photoinduced reactions were monitored by differential photocalorimetry (DPC).

SUPERMOLECULAR STRUCTURE OF CELLULOSIC FIBERS.

Cellulosic fibers exhibit a variety of supermolecular structures. In industrial practice, smaller differences are evident, such as in the varying dye uptake of different fibers. In general, sorption testing methods are well suited for studying the differences in the physical structure of cellulosic fibers. The classic iodine sorption meth..

EFS KEYS MODERN COTTON FIBER PROCESS MANAGEMENT

Managing the selection and cost of raw materials is critical to the success of a fiber processing operation. Approximately 52 percent of the value of a pound of yarn is tied directly to the cost of the raw material. The use of a computer-based cotton fiber management system, such as the Engineered Fiber Selection (EFS), can minimize cotto..

TECHNOLOGICAL REPORT ON STANDARD INDIAN COTTONS -- 1988 TO 1989 SEASON.

Standard Indian Cottons are those varieties whose production exceeds 50,000 bales per year. The Cotton Technological Research Laboratory tests samples of varieties that are grown under specified conditions. Data on the crop from the 1988/1989 season are complied. Data on cultivation include bolls and seeds per plant, weight of seed and bo..

TECHNOLOGICAL REPORT ON TRADE VERIETIES OF INDIAN COTTONS FROM 1988 TO 1989.

The Cotton Agricultural Research Laboratory in India tests samples of trade varieties of cotton grown each season. Data on cotton grown during the 1988/1989 season are complied. The Grader's Report includes class, color, staple length and strength, regularity, and value. Fiber and yarn properties are tested in the laboratory. Data on cult..

GLIMPSES OF WORLD COTTON -- INDIA.

India, the largest cotton-growing country in the world, has increased its production dramatically over the past 30 years due to the production of hybrid cottons, the use of irrigation, and improved pest control. India is one of eight countries to produce long staple cotton and, with its quality hybride production, has raised cotton produc..

TEXTILE DEGRADATION

Recent literature dealing with the causes, mechanisms, effects, methods of assessing, and methods of reducing textile degradation is reviewed. The process of degradation in textile materials involves changes in the molecular structure that cause adverse physical and chemical changes. The scope of this study is limited to literature from t..

ULTRASONICS AND ITS APPLICATION IN THE FIELD OF TEXTILES.

A review of the patent literature reveals that concepts of bonding thermoplastic fibrous structures by means of ultrasonic energy first emerged around 1966. By the early 1970's, the Pinsonic Process, developed by Hunter Machine Company, became available for the continuous manufacture of quilted materials. A machine of the Pinsonic type ca..

TECHNOLOGICAL REPORT ON STANDARD INDIAN COTTONS -- 1987-1988 SEASON.

The fiber characteristics and spinning performance of seven standard varieties of Indian cottons were examined. A Baer sorter calculated mean fiber lengths. A digital fibrograph determined the 2.5 percent span lengths and uniformity ratios. Fiber fineness was determined both gravimetrically and by micronaire. The fiber maturity was graded..

TECHNOLOGICAL REPORT ON TRADE VARIETIES OF INDIAN COTTONS -- 1987- 1988 SEASON.

The fiber characteristics and spinning performance on 39 chief trade varieties of Indian cottons were examined. Mean fiber lengths were obtained by using a Baer sorter. A digital fibrograph determined the 2.5 percent span lengths and the uniformity ratios. Bundle-strength values were obtained by using a Pressley strength stelometer. A Shi..
