Narrow textiles

A length of narrow textile material which is tightly wrapped round a product, e.g., wrapped hose, to apply pressure during vulcanisation. The term is used also in the sense of lining. 

Braid n. (1) A narrow textile band, often used as trimming or binding, formed by plaiting several strands of yarn. The fabric is formed by interfacing the yarns diagonally to the production axis of the material. (2) In aerospace textiles, a system of three or more yarns which are interlaced in such a way that no two yarns are twisted around each other. 

Aronnd 10% of all new substances registered are nsed for the purposes of plastics processing. A further approximately 10% of new substance registrations are in each case for (i) dyes (especially for the textile industry) and (ii) photochemicals (photographic industiy and toners in the paper industry) and also (iii) cosmetics and perfumes. The majority of relevant substance innovations appear to take place in this relatively narrow market sector, while here too a relevant proportion of process iimovations could be in processing (with the exception of cosmetics and perfumes). 

Women tend to work in a narrow range of traditional female jobs (11). In Finland. 45 % of the women were employed in occupations totally predominated by women at least 91 % of the workers were women (12). Women are most often employed as service workers, clerical workers, or professional and technical workers. For instance, in Finland the most common occupations of women in i960 were farm worker, cleaning woman, sales worker, office clerk and nurse (13). Typical occupations of women in industry are textile, clothing, food industry, or packing work. 

Products Homopolymers can be produced with melt flows from less than 0.1 to 3,000 and isotactic content up to 99%. Random copolymers can be produced with up to 12 wt% ethylene or up to 21 wt% butene over a wide melt flow range (<0.1 to >100). A full range of impact copolymers can be polymerized with a good stiffness to impact balance. Products from narrow to broad molecular-weight distribution can be manufactured in grades suitable for film injection, molding, blow molding, extrusion and textile applications. 

This aqueous solution of a substituted starch provides excellent body and stiffness on textiles and narrow fabrics. 

One of the earliest uses of power ultrasound in processing was in emulsification. If a bubble collapses near the phase boundary of two immiscible liquids, the resultant shock wave can provide a very efficient mixing of the layers. Stable emulsions generated with ultrasound have been used in the textile, cosmetic, pharmaceutical, and food industries. Such emulsions are often more stable than those produced conventionally and often require little, if any, surfactant. Emulsions with smaller droplet sizes within a narrow size distribution are obtained when compared to other methods.

Most chemical products do not reach the ultimate consumer in their original form, but are used as ingredients in the products of other industries— textile, automotive, electrical, paper, and a host of others. Most chemical advertising has in the past been directed to rather narrow industry audiences, and these are, of course, the cheapest to reach. 

A full range of impact copolymers can be polymerized with excellent stiffness for even the most demanding applications. Products from narrow to broad molecular-weight distribution can be manufactured in grades with proven advantage for film injection, molding, blow molding, extrusion and textile applications. 

Test pieces are most often in the form of two-dimensional dumbbell shapes or flat strips, but there are exceptions, such as ring test pieces, sometimes used for rubbers, and three dimensional dumbbells, for certain types of plastic. Dumbbells have the basic attribute of being a way of concentrating the stresses so that failure takes place in the narrow portion and not preferentially where the test piece is gripped, although this is not always successful in practice. For textiles a dumbbell would mean that some threads at the ends were not supported, and no advantage over a flat strip has been found for many plastics films. Particular variations on these shapes have been developed for composite materials to cope with their particular properties. 

Experimental studies of various textile composites show that the maximum possible values of iy-FVF are in a relatively narrow band. Summarising various observations across literature (e.g. [20—22]) it can be stated that (1) actual iy-FVF can hardly exceed 75% and in most cases it is lower, (2) the o-FVF for some typical textile composites is rather high (above 50%) and can exceed 60%. That gives the YVF of 70—80% and higher, which is not easy to achieve in a model.
