Definitions

  • the present invention relates to a stretch fabric with high speed snap back performance, and in particular to a warp knitted fabric formed from hard yarns and elastic yarns.
  • An elastic stretch fabric formed by polyurethane fibers has relatively good snap back performance under low speed and constant speed conditions, but it will not recover in time after stretching under high speed and abrupt-acceleration conditions. Moreover, different knitting stitches generate different binding forces on the stretch fabric, and this binding force will also affect the expansion and contraction performance of the stretch fabric, thereby affecting the snap back performance.
  • Chinese Patent Publication No. CN202323318U discloses a stretch warp knitted fabric, which is knitted by three guide bars, the surface guide bar knits with 20D polyamide yarn , and then the two guide bars respectively knit with 40D, 70D spandex weft laid-in stitches, and the obtained stretch fabric has superior elasticity and softness and is comfortable to wear.
  • Chinese Patent Publication No. CN205077227U discloses a novel warp knitted body shaping stretch fabric which is knitted by three guide bars , specifically, the front guide bar is made of synthetic fiber filaments and knitted by tricot stitches; the middle guide bar alternately knits by using spandex via tricot stitches and two needle stitches ; and the back guide bar knits by using spandex via reserve tricot stitches, and the obtained stretch fabric has different body shaping effects on different portions of the body.
  • Chinese Patent Publication No. CN102648313A discloses an elastic warp knitted fabric, wherein elastic yarns are knitted with knit stitches such as full tricot stitches, two needle stitches or warp sateen stitches, hard yarns are knitted with warp pile stitches or 5-needle warp sateen stitches, the tilt angle of the mesh is 20 to 70 degrees, the obtained stretch fabric has excellent elongation balance and elongation recovery in the warp and weft directions, is well-fitting and unlikely to generate pattern deformation during wear, and has excellent snap back performance , thereby being able to improve the sports functions.
  • knit stitches such as full tricot stitches, two needle stitches or warp sateen stitches

  • the tilt angle of the mesh is 20 to 70 degrees
  • the obtained stretch fabric has excellent elongation balance and elongation recovery in the warp and weft directions, is well-fitting and unlikely to generate pattern deformation during wear,
  • FR 3044217 A describes a compression bandage obtained by warp stitch technology comprising two textile surfaces each including elastic yarns, the surfaces being interconnected by spacer yarns.
  • the object of the present invention is to provide a stretch fabric having excellent snap back performance, which is particularly suitable for motion under high speed and abrupt-acceleration states.
  • the present invention provides a stretch fabric as defined in claim 1.
  • a stretch fabric with snap back performance of the present invention is a warp knitted fabric formed by hard yarns and elastic yarns, wherein the included angle ⁇ between a sinker loop of the elastic yarn and the knitting direction of a loop is 0-10°, and the included angle ⁇ between the sinker loop of the hard yarn and the knitting direction of the loop is 5-85°.
  • the elastic yarn is a polyurethane fiber which is the reaction product of polyether diol having a side chain and a diisocyanate compound with two or more diamine compounds, wherein the molar ratio of ethylenediamine contained in the diamine compound to a branched aliphatic diamine compound having 3 to 5 carbon atoms is 98: 2 to 82: 18.
  • the stretch fabric with snap back performance of the present invention can effectively prevent a wearing pressure increase caused by an elongation stress and a wearing pressure decrease caused by a delayed recovery, particularly under high-speed and abrupt-acceleration conditions, so that wearing comfort can be maintained, and muscle vibration can be prevented.
  • the stretch fabric of the present invention is less prone to problems such as busting and tearing even when being used for a long period of time, and has a long-lasting elastic effect.
  • the stretch fabric of the present invention can be used for making garments suitable for athletes and the like, and is particularly suitable for making tight-fitting athletic wear for top athletes to wear under high speed and abrupt-acceleration conditions.
  • the stretch fabric with excellent snap back performance of the present invention is a warp knitted fabric formed by hard yarns and elastic yarns, wherein the included angle between a sinker loop of the elastic yarn and the knitting direction is 0-10°, and the included angle between the sinker loop of the hard yarn and the knitting direction is 5-85°.
  • the specific structural characteristics of the elastic yarns and the hard yarns in the stretch fabric are key factors determining the snap back performance of the stretch fabric.
  • it is characterized by the included angle formed between the sinker loop and the knitting direction.
  • the specific angle size is observed by a SEM electron microscopy or a digital microscope.
  • the structure of the elastic yarn in the stretch fabric is mainly composed of two portions, namely needle loop and a sinker loop, wherein the needle loops are sequentially connected along the knitting direction and the stretchability can be maximized in the knitting direction .
  • the stretchability of the sinker loop portion it is required that the stretchability of the sinker loop portion should be contributed as much as possible in the knitting direction of the loop, that is, the greater projection amount of the sinker loop of the elastic yarn in the knitting direction of the loop is better, that is, the smaller included angle ⁇ between the sinker loop and the knitting direction of the loop is better.
  • the included angle is minimum and tends to 0°, the stretchability of the sinker loop is almost entirely contributed to the knitting direction of the loop.
  • the included angle ⁇ between the sinker loop of the elastic yarn and the knitting direction should be 0° to 10°, and preferably 2° to 9°.
  • the structure of the hard yarn in the stretch fabric is also composed of needle loop and a sinker loop.
  • the needle loops of the hard yarn are also distributed in the knitting direction, that is, the telescopic motion direction, and the needle loops of the inelastic yarn are overlapped with the needle loops of the elastic yarn.
  • the hard yarn itself has almost no stretchability, so it can only provide a telescopic space for the elastic yarn via the deformation of the loop structure; and on the other hand, as the strength of the hard yarn is higher than that of the elastic yarn, the hard yarn loop plays a certain "reinforcing" effect on the elastic yarn loop, which can improve the strength of the stretch fabric.
  • the sinker loop of the hard yarn can not only ensure the connection between the loops to smoothly form the fabric, but also can restrict the stretchability of the stretch yarn to some extent, that is, affect the snap back performance of the stretch fabric.
  • the snap back performance, the strength and other properties must be evenly distributed, which requires that the structures of the sinker loop of the hard yarn in the stretch fabric must be consistent, that is, the angles between the sinker loop of all hard yarns and the knitting direction of the needle loops should be consistent.
  • the included angle ⁇ between the sinker loop of the hard yarn and the knitting direction of the needle loop is less than 5°, the distribution of the sinker loop is biased toward the knitting direction of the loops, and links between the transverse loops are relatively small, and it is difficult to ensure the smooth knitting of fabric ;
  • the included angle ⁇ between the sinker loop of the hard yarn and the knitting direction of the needle loop is 86° to 90°, the sinker loop of the hard yarn is substantially perpendicular to the knitting direction of the needle loop.
  • the included angle ⁇ between the sinker loop of the hard yarn and the knitting direction should be 5° to 85°, and is preferably 7° to 65°.
  • the elastic yarn mentioned in the present invention is a polyurethane fiber (also called spandex, referred to as PU).
  • PU polyurethane fiber
  • the stretch fabric is required to have small corresponding tensile stress when a large elongation amount is obtained; meanwhile, it is required that the stretch fabric should have good instantaneous recovery and a higher recovery force retention rate.
  • the stretch fabric should maintain its original size and elasticity after repeated reciprocating expansion and contraction.
  • the elastic fiber used in the present invention is polyurethane fiber, which has low stress and high elongation property, can recover after stretching, and has a high recovery strength maintaining rate and good durability, and more specifically soft elastic spandex.
  • the soft elastic spandex refers to a polyurethane fiber obtained after the reaction of polyether diol having a side chain and a diisocyanate compound with two or more diamine compounds, wherein the molar ratio of ethylenediamine contained in the diamine compound to a branched aliphatic diamine compound having 3 to 5 carbon atoms is 98: 2 to 82: 18.
  • the soft elastic spandex used in the present invention has superior softness and elasticity, and its soft elastic index is 0.75-1.
  • the soft elastic index refers to a ratio of the elongation stress at 100% elongation to the recovery stress of 100% recovery after elongation to 300%.
  • the soft elastic index indicates that the soft elastic spandex has a high recovery force retention rate, which is advantageous for improving the elastic recovery of the stretch fabric and reducing the incidence of delayed recovery, thereby improving the motion followability of the stretch fabric.
  • the stretch fabric composed of 100% elastic yarns has the best snap back performance, but such a stretch fabric may have problems such as busting and tearing due to insufficient strength.
  • the hard yarns that is, "hard yarns" are used for reinforcement
  • the elastic stress of the stretch fabric is too small, and the work done to overcome the elastic stress during the stretching process is relatively small. Although it becomes easy to stretch, there is also a problem of insufficient wearing pressure and a tendency of worse muscle vibration prevention effect, and the recovery stress becomes small, and the timely recovery performance at high speed and abrupt acceleration also tends to deteriorate. On the other hand, if the distribution density of the elastic yarns is too large, the elastic stress and the recovery stress of the stretch fabric are too large.
  • the distribution density of the elastic yarns mentioned in the present invention is preferably 30 to 200 w/2.54 cm (30 to 200 w/inch).
  • the hard yarn referred to in the present invention preferably has an elongation of 5 to 50%. Since the yarn needs a certain amount of stretching for bending and circling, in a knitting process, if the elongation is less than 5%, the yarn is liable to break, and the knitting requirement may not be satisfied. When the elongation is greater than 50%, the yarn is likely to be over-drafted in the knitting process, so that the yarn feeding may not be smooth, and the passability may be poor.
  • the fiber raw material of the hard yarn satisfying the above elongation range can be a natural fiber such as cotton or wool, or can be an artificial fiber such as viscose or modal, or a synthetic fiber such as nylon or polyester.
  • nylon and polyester are preferred.
  • the nylon herein includes ordinary nylon and modified nylon (e.g., having hygroscopic groups or the like), and the polyester includes ordinary polyester and modified polyester (e.g., having cationic dyeable groups or the like).
  • the thickness of the yarn also affects the gram weight of the stretch fabric. If the gram weight is too large, the stretch fabric is too thick, the wearing pressure on the human body is relatively large, and the friction force with the skin surface is relatively large, which is not conducive to obtaining a good sport following effect, and also affects knitting comfort. If the gram weight of the stretch fabric is too small, the stretch fabric is too light and thin such that the anti-transparent performance and the like are not ideal enough to meet general cloth requirements. Therefore, it is necessary to make a reasonable choice on the fineness of the yarn used.
  • the hard yarn used in the present invention preferably has a fineness of 10 to 100 deniers (abbreviated as D), namely 11 to 111 dtex, and more preferably 10 to 50 D, namely 11 to 56 dtex, and the elastic yarn has a fineness of preferably 30 to 300 D, namely 33 to 333 dtex, and more preferably 70 to 140 D, namely 78 to 156 dtex.
  • D deniers
  • the hard yarn is selected as a relatively fine yarn as much as possible
  • the elastic yarn is selected as a relatively coarse yarn as much as possible. Therefore, it is preferred that the fineness of the elastic yarn is 1 to 10 times, more preferably 1 to 5 times, as large as the fineness of the inelastic yarn.
  • the present invention adopts a warp knitted stitch for knitting, and the number of guide bars is preferably 2 or 3, the number of guide bars is too large, and the shell fabric is too thick, which may affect the acquisition of the snap back performance effect.
  • the stretch fabric knitted by two guide bars is used as an example, the stretch fabric is divided into four hierarchical structures from the front face of the process to the reverse side of the process, which are respectively a loop surface of a front guide bar, the loop surface of a back guide bar, a sinker loop surface of the back guide bar and the sinker loop surface of the front guide bar and the structure formed by the four layers that are sleeved and connected to each other has better structural compactness and stability than the single-side weft-knitted fabric or a knitted fabric, and can ensure the stable performance of the snap back performance.
  • the elastic yarn is located in the back guide bar, so that both the loop surface and the sinker loop surface are located in the inner layer to prevent the same from being worn and to improve the durability.
  • the stretch fabric knitted by three guide bars is used as an example, the stretch fabric is divided into six hierarchical structures from the front face of the process to the reverse side of the process, which are respectively the loop surface of the front guide bar, the loop surface of a middle guide bar, the loop surface of the back guide bar, the sinker loop surface of the back guide bar, the sinker loop surface of the middle guide bar and the sinker loop surface of the front guide bar.
  • the stretch fabric formed by the three guide bars it is preferred that the front guide bar and the middle guide bar adopt a threading mode of threading one and leaving one and reversely laying the yarns, in this way, the stretch fabric can be prevented from being too thick on one hand, and the stretch fabric structure can be more stable on the other hand.
  • the present invention is produced by conventional refining and dyeing and sorting of a knitted fabric obtained by knitting, and the specific processing conditions are not particularly limited.
