Detailed description of the invention
Below in conjunction with embodiment, knitting fabric of a kind of on-run of the present invention and preparation method thereof is described in further detail.
The coil that traditional latitude jersey is formed by yarn bends mutually wears and constitutes. The elastic deformation relying on coil bending keeps its shape, if somewhere yarn breakage in fabric, coil loses form and press-offs, and punishes solution along stringer from broken yarn and decoherences. If the contact position worn by coil bonds together, yarn broken string circle loses form, but press-offs and will not occur again, is merely creating a duck eye that will not decoherence.
The mentality of designing of the present invention is based on this, as shown in Figure 1, the knitting fabric of a kind of on-run of the present invention, it is the flat pin network structure fabric of the latitude formed by the coil mutually worn, wherein, described coil is to be formed by the plaiting overlap of polyolefin elastic silk wire gauze and staple yarn/long filament, and the front making fabric is staple yarn/long filament, and reverse side is polyolefin elastic silk. Mutually bond after the contact point of the described coil mutually worn is melted.
Polyolefin elastic fiber is the high stretch filament mixed by the olefin copolymer of two kinds of different melting points, after 300% fixed elongation stretches, elastic recovery rate reaches more than 90%, finds that this material has two melting point peak through DSC thermal performance analysis, is 110 DEG C and 160 DEG C respectively. Therefore, when heat setting temperature maintains about 110 DEG C, fiber partial melting, the place of contacting with each other bonds together, and thermal finalization rate reaches the shape-retaining ability of 100%. So utilizing TPO elastic fiber mutually to wear the latitude jersey of formation, after 110 DEG C of thermal finalizations process, the junction point that fixed coil wears, formed without fibre migration, resilient network structure.
But, it is infeasible it is demonstrated experimentally that independent with polyolefin elastic fiber assembling-disassembling, it is necessary to can with traditional staple yarn or long filament Co-knit. Therefore the organizational structure of fabric is full plating structure. All coils in fabric is formed by plaiting and two yarn overlaps of polyolefin elastic silk wire gauze of staple yarn or long filament, and has covering relation, and staple yarn or long filament are in fabric face, and polyolefin elastic silk is in fabric backing.
Concrete preparation technology is as follows: polyolefin elastic silk bigger prolongs elasticity and frictional behavior because having, therefore adopt strip-type colyliform yarn guide Yarn-feeding mechanism, hello yarn tension controls at 6��8CN, and the tension force of plaiting controls within the scope of 1:2 at the thread-feeding amount ratio of 3��5CN, yarn feeding and plaiting. Choose the position of yarn guide during braiding, make the vertical carrying angle of plaiting more than polyolefine fiber, and cross level angle is less than polyolefine fiber, thus ensure that the configuration relation of two yarns. The wire gauze, the plaiting that prepare are woven into semi-finished product fabric through circular knitting machine lopping, Lian Quan.
Semi-finished product fabric carries out thermal finalization process after fully lax elimination fabric residual stress, fabric size can be made stable, reduce washing shrinkage, also can eliminate the defects such as wrinkle rope form fine wrinkle and grin simultaneously. Being defined below heat setting process by testing, adopt pin tentering forming machine, heat setting temperature is set in first fusing point of TPO elastic fiber about 110 DEG C, and the time controls at about 20��40S. To consider that after setting, material has a small amount of contraction, so setting fabric width should than final products fabric width big about 5��15% simultaneously. After hot melt and heat treatment, the contact portion that coil wears mutually bonds together because of melted by heating, forms the fixing network structure without transfer, so the dimensionally stable of product improves, shrinkage reduces, edge-curl phenomenon of decoherencing reduces. As shown in Figure 2.
