Medical textiles is a vibrant emerging field in the area of technical textiles and its category is based on its performance and biofunctional properties for hygienic and health care products. Biodegradable fabrics are widely used for medical textiles in recent years. Seaweeds provide a wide range of therapeutic possibilities for human beings both internally and externally due to the presence of bioactive compounds. The paper aims to discuss these issues.

This present study investigates the development of bioactive gauze fabric from Chaetomorpha linum seaweed/cotton blended fibres and also analysed the characteristics of Chaetomorpha linum seaweed/cotton blended gauze fabric and 100 per cent cotton gauze fabric. The effect of fibres on physical properties of fabric such as tensile strength, air permeability, wickability, water drop test and colour fastness properties were analysed. The antibacterial properties and antioxidant activity were assessed by DPPH radical scavenging, AATCC 100 and EN ISO 20645 test methods.

The experimental results indicate that the maximum antioxidant activity of 103.28±1.23 per cent inhibition was achieved at minimum concentration (500 µg/ml) of the blended fabric extract, and maximum antibacterial reduction of 95 per cent and zone of inhibition of about 26 mm were achieved in a blended fabric. The tensile strength, percentage of elongation and air permeability were more or less the same in both gauze fabrics. It is also found that Chaetomorpha linum seaweed/cotton blended gauze fabric exhibit better wickability and water absorbency properties than 100 per cent cotton gauze fabric. The colour fastness properties to washing and rubbing showed excellent results in the blended gauze fabric, and it is used for making wound dressing materials.

This bioactive gauze fabric was used for non-implantable materials such as wound healing, face mask, surgical gowns and hygienic textiles in recent years.

Examines the effects of directional variations in woven fabric properties on the behaviour of fabrics as they are plied and sewn together to form a seam. This is an important practical consideration, since garment manufacturing frequently involves the sewing of two fabric plies of completely different and constantly changing bias angles — none of which is along the grain line. Examines the variations in the properties of five woven materials, all lightweight and commonly used in women's summer apparel. The Kawabata Evaluation System (KES) was used to measure the mechanical and surface properties of strips, cut at different angles, from the test materials. To investigate the effect of orientation on seam quality, two plies cut from the same fabric but at different angles were sewn together under selected conditions. The resulting seams were characterized for seam quality using AATCC standards.

The blades of an airscrew or spars and similar hollow structural parts of aircraft are formed of two shell sections of wood laminæ joined together with a moisture‐resisting adhesive, each shell section forming in the case of a blade substantially one face of the blade and being made by assembling very thin wood laminæ between shaped dies, which dies may be heated as well as pressed together. The wood laminæ is preferable less than one millimetre in thickness and the laminæ may be assembled so that parts which take higher stresses are more highly compressed. The laminæ 9 are treated with a resin and pressed between the dies, 7, 8 which have tubes 10 for conveying a heating medium. After pressing, the parts may be clamped together while the shell member is setting, and finally the free edges 11 are cut away. If desired, the shell‐like members 2, 3 may be strengthened by inner longitudinal ribs 22 and the parts are subsequently united by gluing at the leading and trailing edges. For the purpose of securing the blade root within a cylindrical socket, it may have an inner stiffening tube 15 and an outer hardwood sleeve 17 to which a metal sleeve 16 is attached. Alternatively, the hardwood sleeve and metal sleeve are both placed inside and outer clamping sleeves are employed. The shell members 2, 3 may be enclosed in a metal sheeting 23, 24, the edges of which are joined by welding or by interlocking the edges 25. The leading edge may be formed by a separate member 30 dovetailed as at 34 into the outer shells, and such member may be formed with a rubber tip 37 or be wholly of rubber. The resistance to bending stresses may be increased by loading the blade tip either by adding weight or using material of high density. The wood laminæ may be interleaved with laminæ of other suitable pliable material such as fabric or metal gauze.

The theoretical analysis indicates that the main factors of cover‐shelter properties of fabrics are cover factor of fabrics, fabric thickness, optical reflectance and absorbance of yarn. With a combination of distances and luminances, 512 experiments have been made to find out the relationship between the least distinguishable distance and reflectance coefficient.

SAND is very harmful to engines. During recent tests conducted by me in the North African Deserts, as much as half a pound of sand has been collected in ten minutes in each air intake of a Mosquito aircraft taxying, alone, downwind on a desert airfield. Had the Mosquito been following another aircraft, or had its air intake been situated lower, the quantity of sand would have been much larger. Under such conditions the importance of having efficient air cleaning intakes fitted to every aircraft engine is obvious. Sandy conditions are not confined to desert airfields, some airfields in this country and on the Continent are as bad.

Apparatus, for the lateral control of aeroplanes, comprises spoiler vanes adapted to be projected from the upper surface of the wings by the operation of a manual control device which operates so that a uniform increase in the displacement of the control device through substantially its full range of movement is arranged to effect a continuously decreasing increase in the effective extent of the projection of the spoiler vanes, whereby the rolling moment of the aeroplane is continuously increased during the displacement of the control device. The spoiler vane may be divided into two or more unequal sections in the direction of the wing span and the control device constructed so that in its initial movement it projects the smaller vane at a rapid rate and subsequently raises the larger vane or vanes at a reduced rate. In Fig. 7 (not shown), the spoiler vane is projected by a rotatable bell‐crank lever positioned so that rapid regular movement of the vane is attained during the initial movement of the bell‐crank lever. In an alternative construction Fig. 8 (not shown), a roller on the arm of a bell‐crank lever engages a cam‐shaped surface on the underside of the spoiler vane. As shown in Figs. 9, 10 the initial rapid movement may be effected by a shaped cam It and where the spoiler vane is divided into two unequal portions, the smaller part is projected by a cam k as shown in Fig. 9, whilst the slower movement of the larger vane is effected by a differently‐shaped cam k as shown in Fig. 10. In a modification Figs. 11, 12 the vane b is torsionally twisted, about an edge in the wing by a set of cams p1 . . p4 arranged along a rotatable shaft o and arranged to come into action successively with a decreasing rate of projection of the vane. In a further modified construction, Fig. 13, a vane b is projected from a slit in the wing d by a slider s formed with arms z1, z2 which engage lugs u2, u1 carried by the vane. The width of the vane may be varied along its length so that the area projected during the initial movement of the control member is additionally increased. The spoiler vanes may be held in their normal positions by springs arranged so that the spoiler vanes are automatically projected from their normal position when the pressure on the wing in the locality of the vanes is abnormally low, e.g., under high list conditions.

Synthetic resin‐based paints, for use in water‐coating techniques for painting gas holders, are applied to water and the holder moved up and down past this water seal. The use of this technique has previously given trouble because of the emulsification of the paint when pumped around, and a poor, wrinkled finish which does not adhere well. With the formulations given in this patent, coatings 4‐mil thick may be applied, equivalent to two standard brush coats.

This article analyses the issue of discipline violations in a Russian textile company. Discipline violations proliferated in Soviet times and were tolerated by managers. The cause has been identified in the limited form of control exercised over the production process, resulting from the social relations existing in the Soviet Union. Evidence from the case study indicates that no fundamental change has occurred in this area since the transition. The research documents the material and psychological hardships experienced by workers, the relational practices constraining line managers, and it tries to discern the conceptual and operative limits of disciplinary campaigns by top management.

Non‐recovery of wool Futon padding was investigated by compression and creep tests. Simulation tests are also carried out to use the minuter model Futon. Fibre crimp was found to be an important parameter to be considered in the non‐recovery of Futon. Futon padding which consists of crimpy fibre has large apparent fibre density and shows less reduction of thickness compared with those made from uncrimpy fibres. The moisture inside and outside the Futon has a large influence on the recovery process.
