Abstract: A heat adhesive tape comprising a tape main body of heat-resistant woven or knitted fabric and a heat adhesive thread of thermoplastic resin provided at each side of the main body on one surface thereof. To form a finished hem on trousers, skirts or the like, the tape is placed on the main body of the hem portion and on a folded-back portion of the hem portion and then heat-pressed as by ironing. The heat adhesive thread is woven or knitted into the main body zigzag in a staggered or wavy form or in the form of a series of turns and is thereby made almost free of shrinkage longitudinally of the tape when heat-pressed. A thermoplastic resin thread meltable at a lower temperature than the adhesive thread and fastening the thread to the main body at its furrow portions melts before the adhesive thread during heat pressing so as not to permit the adhesive thread to exert a shrinkage force on the main body also widthwise thereof when the tape is heat-pressed.

Abstract: Disclosed is a warp knitted narrow lace and method of forming the same in which purls or decorative loops are formed in a curved line along curved scallops of the lace. This warp knitted narrow lace is manufactured by knitting the base fabric into a Raschel lace having a scalloped edge and simultaneously knitting laid in yarns into the edges forming the scalloped edge of the lace in such manner that the laid in yarns are laid in with stitches of soluble yarns and/or ravel yarns located outside base fabric at the outermost portion of the scalloped edge and with stitches of the base fabric in the indentations of the scallops. Dissolving the soluble yarns and/or pulling out the ravel yarns in the area of the outermost edge of the scallops, and cutting the stitches of the base fabric outwards of the purls in the indentations of the scallops results in the formation of a novel lace having purls formed in a curved line along the entire scallops.

Abstract: Fibrillatable multicomponent fibers of the matrix segment type and a process for production of fiber structures by splitting shrinkable, basically unset, multi-component fibers consisting of at least two incompatible components which in the fiber cross section are arranged in the form of a matrix and several segments, the latter accounting for about 20% to 80% of the total cross section. After having been processed into fiber structures such as staple fibers, yarns or fabrics, the multicomponent fibers are treated with a liquid or gaseous organic solvent, particularly chlorinated lower alkanes, to partially or completely split the segment filaments from the matrix component. Useful solvents are those which will reduce the zero-shrinkage temperature of the matrix or the segment polymer by at least 160.degree. C. and in which the polymer components constituting the fiber show different shrinkage behavior. Splitting may be further enhanced by the application of mechanical agitation, e.g. by ultrasonic waves.

Abstract: A double knit fabric includes a plurality of courses knitted to form first and second sets of alternating wales. The first set of alternating wales forms the face of the fabric while the second set of alternating wales forms the reverse side of the fabric. The courses are knitted in a preselected pattern to form stitches which join the courses together at selected wales. First yarns are used to form selected courses with the first yarns having a higher shrinkability than second yarns forming the remainder of the courses. Selected second yarns are knit in a pattern which allows portions of the second yarns to float on the face of the fabric. The floating portions are formed by causing the yarn to welt or miss at least two consecutive wales of the first set of alternating wales.

Abstract: Novel block copolymer formed by melt blending a melt spinnable polyamide, such as nylon-6, and a poly(dioxa-arylamide), such as poly(4,7-dioxadecamethylene terephthalamide) (also known as N-30203-T), is disclosed. Said copolymer has utility as a fiber. The fiber of a block copolymer, for example of nylon-6 and said poly(dioxa-arylamide) which is also known as N-30203-T/6, has superior moisture absorption and initial modulus characteristics than that of nylon-6. Furthermore, resulting fiber still substantially maintains the other desirable properties of the major constituent, for example, nylon-6.

Abstract: A method for producing conventionally usable, stable, preshrunk and crimped yarn from greige self-crimping bicomponent or biconstituent yarn. The method employs a knit-de-knit procedure to impart a so-called mechanical crimp in the self-crimping yarn as that yarn is subjected to an initial heat treatment. The knit-de-knit process has been modified in order to knit the knit-de-knit tubular sleeve more loosely and to obtain a crimp rate per thread line inch within a predetermined range. The knit tubular sleeve is collected in the form of a fabric roll, the internal diameter of which is controlled so that during heating the yarn crimp can develop uniformly. The yarn produced thereby can be used to produce "to size" greige fabric or garments which exhibit better snag or pick resistance than such fabrics or garments produced from conventional greige yarn. These fabrics or garments can thereafter be subjected to normal finishing procedures.

Abstract: An improved apparatus capable of carrying out a continuous method of forming yarn elements from a supply roll of thermoplastic film, which method is characterized by slitting the roll into flat strips of preselected width, simultaneously subjecting the strips to heat and to a pulling or drawing force to elongate the strips which reduces their width and at the same time minimizes their subsequent stretch capability, and thereafter interengaging said strips on a textile-forming machine, such as a knitting or weaving apparatus, to form a desired product. The method is particularly adaptable to the production of an improved knitted bag formed of said flat yarn elements.

Abstract: The snag resistant leg portion of this hosiery article is knit of a composite self-crimping yarn including a series of mechanical crimps imparted thereto prior to knitting, and a series of crimps imparted to the composite yarn by development of the latent crimp in the composite yarn after knitting. The hosiery article knit of the composite self-comprising yarn having both types of crimp therein has much greater snag or pick resistance than either a hosiery article knit of the same type of composite yarn but including only the crimps imparted by development of the latent crimp in the yarn, or a hosiery article knit of yarn having mechanical crimp only. The knitting of a mechanically crimped composite yarn also produces a normal size greige hosiery article blank which may be processed in the usual manner to produce the finished hosiery article.
