Description

Technical Field

[0001] The invention relates to a terry fabric, in particular to a knitted fabric with terry loops directly formed by knitting structural units. Background Art

[0002] With the continuous improvement of living standards, consumers have higher requirements for the comfort, functionality and appearance of warm clothing or bathroom products. Among them, Terry fabrics are not only expected to have excellent comfort, fluffiness and thermal insulation, but also to have more diverse appearance. Currently, Terry fabrics on the market are mainly woven by Terry machines, flat knitting machines and tricot warp knitting machines, but the Terry of the three is an elongated sinking arc, and the appearance is not rich and diverse enough.

[0003] For example, Japanese patent document Tokukai 2020-59963 discloses a single-sided terry knitted fabric and a shoe interior material, specifically disclosing a knitted fabric containing synthetic fibers, including a base portion formed by a knitted structure and a terry portion arranged on the upper part of one side of the front base portion, the thickness of the front base portion is 0.3 to 2.0 mm, and the pile length of the front loop portion is 0.5 to 3.0 mm. In a plan view, the area ratio of the front loop portion is 30% to 80% relative to the front base portion. Such a fabric is not only light and thin, but also has good wear resistance, water retention and dry touch in the water-absorbing state. However, since the terry is formed by an elongated sedimentation arc, the appearance change of the terry is relatively limited, and the terry is prone to collapse and deformation during wearing.

[0004] For another example, Chinese patent document CN103668733A discloses a terry knitting method and a knitted fabric having a terry knitted fabric portion, and specifically discloses that the knitted fabric is woven using a flat knitting machine, the terry knitted fabric portion has a base portion woven by connecting warp threads and a terry loop formed by a portion of the terry yarn woven into the base portion, the base portion is composed of a plurality of joining portion coils and a plurality of loops, the terry yarn is woven into the base portion by overlapping the terry yarn loops on each joining portion coil, the terry loop is formed by connecting the closest loops in the knitting width direction in the terry yarn, there are no portions in the terry knitted fabric portion where the joining portion coils are continuous for more than 4 portions in the knitting width direction, such a knitted fabric is still woven by a terry machine, the terry structure of the fabric is formed by an elongated sinking arc, the terry loop has poor stability, and will deform when subjected to tension, and the terry yarn may even be easily pulled out during use, thereby affecting the stability of the base surface where the terry loop is located.

[0005] For another example, Chinese patent document CN108411461A discloses a terry fabric and a method for producing the terry fabric, specifically disclosing that the terry fabric includes an outer terry layer and an inner terry layer, which are woven into a grey cloth by knitting or weaving technology. However, the problem of poor stability of the terry fabric is still not solved. Summary of the invention

[0006] The object of the present invention is to provide a terry fabric with rich terry appearance changes, stable terry and not easy to deform.

[0007] The technical solution of the present invention is as follows: (1) Terry fabric, the loops are all formed by loop structural units, or are all formed by suspended arcs longer than the unit float length, or are formed by loop structural units and suspended arcs longer than the unit float length; and adjacent loops are separated by at least one wale.

[0008] (2) For the terry fabric described in (1) above, the height of the terry is not less than 0.20 mm.

[0009] (3) The terry fabric of (1) or (2) above, which is a double-sided terry fabric.

[0010] (4) The terry fabric of (1) or (2) above, wherein the yarn raw material forming the fabric comprises at least polyester fiber and / or polyacrylonitrile fiber.

[0011] (5) The terry fabric of (1) or (2) above, having a thermal insulation value of 0.700 or more.

[0012] The terry fabric of the present invention does not require a terry machine and is woven by ordinary circular knitting equipment. The appearance of the fabric can be changed by changing the structure design, thereby enriching the appearance style of the terry fabric. Moreover, compared with ordinary terry structures, the terry yarn in the fabric of the present invention is not easy to be drawn out, and has a more stable effect. Moreover, the warmth retention is comparable to or even better than that of sanded fabrics or raised fabrics, thereby avoiding the problem of fiber falling of sanded fabrics or raised fabrics. The terry fabric of the present invention can be widely used in making jackets, thermal underwear, pants, sports thermal sweatshirts, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the loop shape of Example 1 of the present invention. DETAILED DESCRIPTION

[0014] The loop fabric is characterized in that: the loops of the fabric are all formed by loop structure units, or are all formed by suspended arcs longer than the unit float length, or are formed by loop structure units and suspended arcs longer than the unit float length; there is at least one coil wale between adjacent loops. The loop here refers to the woven unit in a raised state observed on the transverse section, specifically refers to the coil in the fabric with the head end in a free and unrestrained state.

[0015] In the horizontal direction of the fabric, there is at least one wale between adjacent loops. To ensure the excellent warmth retention of the loop fabric, it is preferred that there are 1 to 3 wales between adjacent loops.

[0016] When two or more wales are spaced between adjacent loops, a corduroy appearance can be obtained, which has better elasticity and wear resistance than ordinary corduroy fabric. More preferably, three wales are spaced between adjacent loops, which gives an appearance most similar to corduroy.

[0017] Preferably, the height of the loops in the fabric of the present invention is not less than 0.20 mm. The height of the loops here refers to the straight-line distance between the highest point of the loops and the point perpendicular to the plane where the base surface of the loops is located. Considering the warmth retention of the fabric, the height of the loops is more preferably 0.80 to 1.20 mm.

[0018] The present invention can be woven by an ordinary single-sided circular knitting machine or a double-sided circular knitting machine, and no special terry equipment is needed. When a double-sided circular knitting machine is used for knitting, terry loops can be formed on only one side of the fabric, or on both sides of the fabric. Considering the thermal insulation of the fabric, it is preferred to distribute the terry loops on both sides; considering the stability and firmness of the terry loops, it is preferred to distribute the terry loops on one side.

[0019] The terry fabric of the present invention can be obtained by knitting using a common circular knitting machine. The circular knitting machine used is not particularly limited, and can be a 24G double-sided circular knitting machine, an 18G double-sided circular knitting machine, a 28G single-sided circular knitting machine, etc.

[0020] On a circular knitting machine, at least non-dissolving yarn A and dissolving yarn are selected for weaving to obtain grey cloth, which is then subjected to post-processing including pre-treatment, dyeing, and shaping to obtain a product.

[0021] The dissolvable yarn here refers to fibers that can be dissolved in water or alkaline solution, for example, water-soluble vinylon, water-soluble PET fiber, alkali-soluble PET fiber, etc.

[0022] The fiber raw material of the non-dissolving yarn A is not particularly limited, and can be natural fibers such as cotton, linen, silk, wool, etc., or artificial fibers such as viscose and acetate, or synthetic fibers such as polyester fibers, polyamide fibers, and polyacrylonitrile fibers. Among them, when the fiber raw material of the non-dissolving yarn A is a natural fiber, preferably a yarn with a thickness of 60 or more, so that the adjustable range of the braided line length is larger and the firmness of the terry is better; when the fiber raw material of the non-dissolving yarn A is a synthetic fiber, the cross-sectional shape of the fiber can be circular, elliptical, W-shaped, hollow, core-sheath, etc. In addition, the shape of the yarn is not particularly limited, and can be a fully drawn yarn FDY, a false twisted yarn DTY, etc., preferably DTY, and the resulting fabric feels more fluffy and soft. The non-dissolving yarn A is preferably DTY with a fineness of more than 75D and an F number of more than 36. In the present invention, as a preference, the fiber raw material of the non-dissolving yarn A includes at least ordinary polyester fiber and / or polyacrylonitrile fiber. This is because ordinary polyester fiber, as a type of synthetic fiber, has a wide range of applications and low cost; while polyacrylonitrile fiber (acrylic) is fluffy, curly, soft, and has a warmth retention rate that is about 15% higher than wool. It is known as synthetic wool and can improve the thermal insulation of fabrics compared to other fiber raw materials.

[0023] During the knitting process, if a double-sided weave is used, non-dissolving yarns A with different boiling water shrinkage rates can be fed simultaneously, so as to form a high-low terry fabric simulating the style of animal fur with good thermal insulation. The non-dissolving yarns A here can be 2 or 3 or more yarns with different boiling water shrinkage rates, among which the difference between the largest boiling water shrinkage rate and the smallest boiling water shrinkage rate is more than 3%.

[0024] The fabric structure of the present invention is not particularly limited, and can be a single-sided structure or a double-sided structure. In the case of a single-sided structure, the non-terry surface can have a plain appearance effect or a beaded mesh appearance effect. In the case of a double-sided structure, the single-sided structure can have a terry effect or a double-sided structure. Among them, when the single-sided structure has a terry effect, the non-terry surface can have a plain appearance beaded, corduroy or other appearance effects. When a double-sided structure with a terry effect on one side is used, the connecting yarn connecting the terry surface and the non-terry surface is preferably an elastic yarn with a certain elasticity, such as PBT / PET, polyurethane PU, etc. Using such an elastic yarn as a non-dissolving yarn C can make the fabric tighter and the cloth surface effect better.

[0025] In the above-mentioned shaping process, functional resins such as waterproof resin, water-absorbing resin and antistatic resin can be selected for processing as needed. The waterproof resin is not particularly limited here, and examples thereof include silicone resin, carbon 6 fluorine resin, etc., and the amount thereof is preferably 30 to 80 g / L; the water-absorbing resin is not particularly limited here, and examples thereof include polyester resin, etc., and the amount thereof is preferably 20 to 50 g / L. The antistatic resin is not particularly limited here, and examples thereof include ester ether resin, etc., and the amount thereof is preferably 10 to 60 g / L.

[0026] Preferably, the Terry fabric of the present invention has a thermal insulation value of 0.700 or more.

[0027] The present invention is further described below with reference to embodiments and comparative examples.

[0028] The test methods of various parameters involved in the present invention are as follows: (1) Loop height First, cut three pieces of fabric samples with a length of 5.0 cm and a width of 1.0 cm along the horizontal direction of the coils. Take one of the pieces of fabric samples and paste any of the two sections along the horizontal direction on a hard cardboard (if the fabric sample is light-colored, paste the fabric sample on black hard cardboard, otherwise, paste it on white hard cardboard), and then use a KEYENCE VHX-2000C microscope to observe the other section of the fabric sample along the horizontal direction. Specifically: adjust the microscope magnification to 50 times and measure the height of the pile at the observation point. Determine the lowest point on both sides of the pile sinking arc, connect these two lowest points to get line segment L, draw a parallel line of line segment L, get the tangent point of the parallel line and the pile loop column, and the vertical distance from the tangent point to line segment L is the height of the pile. According to this method, measure the pile loops at 10 locations of the sample fabric, and get a total of 10 sets of data. Remove the two larger values ​​and the two smaller values, and get the average of the 6 values ​​in the middle. The remaining two pieces of fabric samples were measured in the same manner to obtain a total of three sets of data, and the average value was taken as the pile height of the present invention.

[0029] (2) Thermal insulation CLO value The test samples were placed in a constant temperature and humidity environment (65±4%RH, 20±2℃) for more than 12 hours and then tested according to the KES method.

[0030] (3) Boiling water shrinkage Take the test skein from the packaged yarn with a yarn length gauge, wind it for 10 meters (1 turn = 1 meter), and pre-tension FDY: 0.05g / D, DTY: 0.1g / D, short fiber: 0.5cN / tex. Gently remove the skein from the yarn length gauge without any tension, and hang it on the yarn rack without any tension. Balance the skein under standard atmosphere for more than 12 hours before heat treatment. Apply the specified load (FDY: D×0.05g / D×10×2, DTY: D×0.1g / D×10×2, short fiber yarn: tex×0.5cN / tex×10×2) to the lower end of the skein on the yarn rack. And prevent the skein from twisting. After 30±3 seconds, read the yarn length L1 before heat treatment, accurate to 1 mm. Fold the yarn in half and then in half again, gently put it into the mesh bag in a relaxed state, tighten the bag mouth to ensure that the yarn will not leak out during heat treatment. Pour soft water into the constant temperature water tank to ensure that the water temperature remains constant at 98°C, the water in the water tank flows evenly, and the sample is heated evenly. After 30 minutes, drain the mesh bag for 30 seconds and take it out. After cooling for 10 minutes, take it out for testing. Hang it on the yarn rack in a relaxed state and balance it in a standard atmosphere for more than 12 hours. Hang the sample on a manual length measuring instrument, apply the specified load, and prevent the twisted yarn from twisting. After waiting for 30±3 seconds, read the length L2 of the sample after heat treatment, accurate to 1 mm. The calculation formula for boiling water shrinkage is as follows: S=[(L1-L2) / L1]×100 Where: S: boiling water shrinkage, % L1: Length of the sample before heat treatment, mm L2: Length of the sample after heat treatment, mm According to the same method, three samples are measured to obtain three groups of data, and the average value is the boiling water shrinkage of the present invention.

[0031] (4) Loop stability The stability of the terry is confirmed by pulling the terry surface on the fabric for a certain number of times under a certain load and observing the deformation degree of the terry on the fabric after the pulling test. The details are as follows: cut 5 pieces of sample cloth with a length of 10.0cm and a width of 5.0cm along the horizontal direction of the coil. Take one of the sample cloths, fix it on the laboratory table with the terry surface facing up; stick a Velcro with a length of 7.0cm and a width of 3.0cm on the terry surface, and add a load of 1kg (9.8N). After 3 seconds, remove the load and pull up the Velcro; repeat the above operation for a total of 5 times; under natural light, according to the following description, 5 people visually rate the terry state of the sample cloth (intermediate level, such as 1.5 level, can be taken) and record the results. Test the remaining 4 sample cloths in the same way, and take the average of 25 data for the final result, retaining 1 decimal place.

[0032] Among them, level 5: no appearance change at all; Level 4: There are slight deformation and collapse of the terry loops and changes in appearance; Level 3: There are changes in the appearance of the pile being deformed and falling apart; Level 2: There are many changes in the appearance of the pile being deformed and falling apart; Level 1: There are obvious changes in the appearance of terry loosening and deformation.

[0059] Embodiment 18: The first route uses 50-ne cotton yarn (produced by Shandong Hengtai Textile Co., Ltd.), and the eighth route uses 60-ne water-soluble vinylon staple yarn (produced by Hai'an Tenglong Chemical Fiber Co., Ltd.). The dyeing conditions are reactive dyes, 60°C×60 minutes, and the rest are the same as in Example 02, to obtain a 195 g / m 2 Terry fabric, specific parameters see Table 2.

[0060] Comparative Example 01: On a single needle bed weft knitting terry machine, 1 pass forms a tissue cycle. 100D / 144f PET DTY (manufactured by Jiangsu Hengli Chemical Fiber Co., Ltd.) is used as terry yarn, and 75D / 36f PET DTY (manufactured by Jiangsu Hengli Chemical Fiber Co., Ltd.) is used as ground yarn. The above yarns are fed at the same time for weaving. The ground yarn on the jaw of the sheet forms the ground tissue of the weft plain needle structure, and the terry yarn on the nose of the sheet forms a loop together with the ground yarn, and forms an elongated sinking arc on the reverse side to obtain a grey cloth, which is then refined (90℃×20 minutes) and dyed (130℃×30 minutes). The remaining Example 01 obtains a gram weight of 190 g / m 2 The specific parameters are shown in Table 2.

[0061] Comparative Example 02: On a double-needle bed weft knitting terry machine, 2 routes form a tissue cycle. 100D / 144f PET DTY (produced by Jiangsu Hengli Chemical Fiber Co., Ltd.) is selected as the front and back terry yarns, and 50D / 48f PBT / PET (produced by Jiangsu Shenghong Chemical Fiber Co., Ltd.) is used as the ground tissue yarn. Three yarns are fed at the same time for weaving, and the upper needle forms a loop, the upper needle forms a loop, the lower needle forms a loop, and the lower needle forms a loop; after weaving, 75D / 36f PET DTY forms the ground tissue, and two 100D / 144f PET DTYs form the front elongated sinker loop and the back elongated sinker loop, respectively, to obtain a grey cloth. The rest is the same as in Example 01, and a weight of 270 g / m 2 The specific parameters are shown in Table 2.

[0062] Comparative Example 03: On a warp knitting terry machine, two combs are used for weaving, GB1 uses 100D / 144f PET DTY (produced by Jiangsu Hengli Chemical Fiber Co., Ltd.), GB2 uses 75D / 36f PET DTY (produced by Jiangsu Hengli Chemical Fiber Co., Ltd.), the yarn padding rules of the two combs are GB1: 0-1 / 1-0 / / / , GB2: 1-0 / 1-2 / , and both combs are fully worn. During weaving, the open braided chain of the terry yarn comb GB1 performs yarn padding movement, the terry yarn sinker performs transverse movement, and the terry yarn is bent into a loop on the terry yarn sinker to form a terry loop with an elongated extension line. The rest is the same as in Example 01, and a gram weight of 210 g / m 2 The specific parameters are shown in Table 2.

[0065] According to Table 1 and Table 2, (1) It can be seen from Example 02 and Example 17 that, compared with the terry fabric with a terry height of 0.18 mm, the terry fabric with a terry height of 0.30 mm has higher terry than the latter, has higher thermal insulation and is significantly more stable than the latter.

[0066] (2) It can be seen from Example 06 and Example 13 that, under the same conditions, the double-sided terry fabric has higher terry loops, higher thermal insulation properties, and better terry stability than the single-sided terry fabric.

[0067] (3) It can be seen from Example 16 and Example 18 that, under the same conditions, the acrylic terry fabric has a higher terry, a higher thermal insulation, and a better terry stability than the cotton terry fabric.

[0068] (4) It can be seen from Comparative Example 01 and Example 13 that, under the same conditions, the single-sided terry fabric formed by the sinking arc has a significantly lower terry height than the single-sided terry fabric formed by the loop, and its thermal insulation is also significantly inferior to that of the latter, and its terry stability is poor.

[0069] (5) It can be seen from Comparative Example 02 and Example 01 that, under the same conditions, the double-sided terry fabric formed by the sinking arc has a lower terry height than the double-sided terry fabric formed by the loop, and its thermal insulation is not as good as the latter, and its terry stability is poor.

[0070] (6) It can be seen from Comparative Example 03 and Example 13 that, under the same conditions, the single-sided warp knitted terry fabric formed by the sinking arc has a lower loop height and lower thermal insulation than the single-sided weft knitted terry fabric formed by the loop, and the stability of the loop is poor.
