Abstract: The invention provides a method for knitting and forming a weft-knitted fabric with varying thickness by a flat knitting machine and a weft-knitted fabric thereof. The method is implemented in at least one knitting process of the weft-knitted fabric, comprising steps of: driving the flat knitting machine to knit a basic structure by at least one of two needle beds of the flat knitting machine, and controlling the two needle beds on the flat knitting machine to knit a three-dimensional structure connected with the basic structure. A thickness of the three-dimensional structure is greater than a thickness of the basic structure, the three-dimensional structure comprises two surface layer portions and a supporting portion connected with the two surface layer portions and located between the two surface layer portions. A junction between the three-dimensional structure and the basic structure is without the supporting portion.

Abstract: The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. Needle collision caused by guide bar shogging during pattern loading is avoided. Pattern loading steps of the double needle bar warp knitting machine are simplified; the work intensity is reduced; and the work reliability is improved.

Abstract: A warp knitted textile spacer fabric, a process for producing same, and articles utilizing same are disclosed. The spacer fabric is of an at least six-bar Raschel construction produced on a double needle bar Raschel knitting machine by knitting front and back stretchable fabric substructures of respective sets of ground and elastic yarns interknitted with one another in a stretchable resilient stitch construction while simultaneously knitting at least two sets of monofilament pile yarns in a pile substructure integrated with and extending between the fabric substructures to form pile segments extending transversely between the fabric substructures in differing angular orientations to the widthwise and lengthwise dimensions of the fabric, producing a pyramidal truss-like system of pile segments which maintain the fabric substructures in spaced parallel relation yet are resiliently compressible and resist relative shear movements of the fabric substructures.

Abstract: Novel spatial warp knitted structures are knitted on a double needle bar Raschel machine or a spatial warp knitting machine formed by modifying a double needle bar Raschel machine. A basic spatial warp knitted structure including two warp knitted fabrics facing each other, uniting threads uniting the two warp knitted fabrics, and insert warp threads and/or insert weft threads inserted between and in parallel to the two warp knitted fabrics so as to intersect the uniting threads or to be interlaced with the uniting threads.

Abstract: A burning wick for hydrocarbons and the like is manufactured by continuously forming two wick bodies by two juxtaposed raschel knitting machines, and then fastening the two bodies together transversely along spaced lines, by wrap yarns or other linking yarns. The composite strip thus formed is then cut off along those transverse junction lines, to provide a plurality of separate cylindrical sleeves, each of which serves as a wick. The individual knit wick bodies can have various weaves across their transverse width, such as a burning portion at one edge, an intermediate suction portion for drawing up the fuel, and a bending or stretching portion between the edges of the body and characterized by a reduced number of weft yarns. In this way a cylindrical wick is produced which has various characteristics along its axial length.

Abstract: A knitting technique in which opposed needles reciprocate towards and past one another in a time-varying motion which is at least principally lengthwise of the needle. One needle approaches and picks up a yarn-end from another needle and forms a loop in the yarn and over the one needle while the other needle withdraws. The other needle then approaches in its turn to pick up a yarn-end and form a further loop while the one needle sheds its loop on to the yarn-end now picked up to form the further loop, the cycle continuing to produce a seam of linked loops. Shogging action by needles and/or associated yarn-control elements produces seam interaction to link seams weft-wise as a knitted fabric. More complex interaction produces patterned fabrics and other knits where yarns link across several wales. An apparatus to carry out the technique includes a needle motion drive using linkages to produce a durable and precise drive action.

Abstract: A velvet-type or snap-together fastener web comprises a warp-knitted ground structure and series of interlooped loops disposed in at least every other wale, each loop including a pair of mushroomed stems projecting from the wale at each course. To produce such a fastener web, a double-faced fabric is knitted on a Raschel warp knitting machine, and is separated into a plurality of strips by dissolving transversely spaced water-soluble threads in the fabric. Each strip is divided into front and back fabric webs by severing thermoplastic thread portions therebetween, leaving a multiplicity of raised stems on each fabric web. The raised fabrc stems are then heated to mushroom their ends.

Abstract: A double, jacquard-patterned piled fabric is produced on a modified warp-knitting machine having two needle-rows whose needles form needle-pairs. Each needle-pair receives a respective set of pile threads, differing ones of which are at different points in a pattern to become patterning pile threads visible in the fabric's pile pattern. When a given pile thread is to be non-patterning, it is tied into one of the two ground fabrics in the form of a walewise-running unlooped thread, and is not knitted into the ground fabric in the form of either half or full loops, in order to greatly reduce the rate of consumption of non-patterning pile thread. When a pile thread is to become a patterning pile thread, it is displaced into the zone intermediate the two needle rows and incorporated into alternate ones of the two ground fabrics in the form of half-loops.
