    A theoretical analysis is given of the bending behavior of warp knit fabrics of two -bar tricot, and a method for making a prediction of the elastic component of the bending property is developed in the case when the radius of curvature is large.
    The values required for calculation are the bending and torsional properties of the constituent yarns and the structural constants of the fabric.
    In this analysis, the following are assumed : (1) a unit structure has three arcs of front -bar yarn and the same number of arcs of back-bar yarn, (2) the crossover region in unit structure is not deformed, (3) the deformation of an arc is, small and prefectly elastic, (4) no frictional restraint exists, (5) curling couple is zero. A theoretical expression is derived from the resistances to bend these arcs out of its plane of initial curvature, and to twist some part of the loop.
    As a course-way bending and a wale=way bending differ in mechanism and also the behavior is markedly asymmetry, its differences are examined in details . Finally, some examples of the calculation are shown to account for its characteristics.

    From the point of view of fiber wrapping on combing roller, effects of velocity of combing roller, types of teeth of metalic wire, delivery speed of sliver and fiber orientation in sliver were studied.
    Results obtained are as follows :
    1) The quantity of fibers wrapped around the combing rollers decrease exponentially as the velocity of rotation of rollers increase.
    2) The quantity of fibers wrapped around the combing roller increases as the quantity of slivers fed to combing rollers increase.
    3) The relation between the number of rotation, N, of the combing rollers at which the fibers initially wrap the roller and the quantity of slivers supplied, F, are approximately expressed as the following formula.
    N=aFb
    where a and b are constants depending on types of teeth, fiber orientation in slivers, direction of slivers supplied etc.

    To reduce the noise level of shuttle loom, the performance of several acoustic materials for an enclosure of a shuttle loom was investigated.
    In the present investigation, six kinds of acoustic materials, steel, polyurethane foam sheets, fibre glass board and damping sheets, were used as the materials of a 80 ×80 sound box (a simulater of noise source in loom).
    Inside of the box, three types of sound speakers were equipped as the sound sources. The sound pressure levels inside and outside of the box were measured according to the materials used.
    Some of the results obtained by using the simulater were applyed to the sound proof loom made, previously, by I. R. I. I.
    From the present investigation, it was found that the sound proofing by using the enclosure to the noise sources in the shuttle loom was not a superior way but more easier way to reduce a reasonable amount of the noise level to compared with mechanical remodelling.
