Description

Technical Field

[0001] The invention relates to the field of textile technology, and in particular to a soft woven label and a preparation method thereof. Background Art

[0002] Woven labels are cloth labels woven onto clothes, pants and other objects, which contain text, letters or LOGO patterns and other marks. For example, clothing factories, garment factories, home textile factories and other manufacturers will use woven labels when producing, manufacturing, processing or selling clothing and home textiles to mark the source of their clothing and home textiles. They generally include text, graphics, letters, numbers, three-dimensional marks, colors and other elements or a combination of these elements, and are marks with distinctive characteristics.

[0003] Woven labels are generally made on a woven label machine by fixing the warp yarn and using the weft yarn to express text, graphics, letters, numbers, three-dimensional logos, color combinations, etc. They are high-end, strong, and have clear lines. Woven labels are mainly divided into two types according to the process: selvedge fabric labels and trimmed fabric labels. Among them, trimmed fabric labels are woven in a whole piece on a special high-speed machine like weaving cloth, and then cut into strips according to the width of the label. Therefore, they have high output and are easier to mass produce.

[0004] However, the cut-edge fabric label often uses polyester as the weaving thread. During the cutting process, the polyester is easily melted by heat and sticks together. This can ensure that the edges will not fall apart, but for this reason, the appearance and feel of the cut-edge fabric label will be sacrificed, resulting in the polyester melted cut edges being exposed, the appearance effect is not very good, and more importantly, the feel is rough and not soft. Therefore, the existing technology still needs to be further improved. Summary of the invention

[0005] Based on this, the present invention provides a soft woven label and a preparation method thereof, wherein the soft woven label can have a good appearance and a soft feel without raveling.

[0006] The technical solution of the present invention is as follows.

[0007] The present invention provides a soft woven label, wherein the soft woven label uses high shrinkage yarn and cotton yarn as weft yarn and low elastic polyester yarn as warp yarn, and the mass proportion of the cotton yarn in the weft yarn is ≤45%;

[0008] Wherein, the shrinkage rate of the high shrinkage yarn in boiling water is ≥15%, and the shrinkage rate of the low-elastic polyester yarn in boiling water is ≤1%.

[0009] In the above-mentioned soft woven label, high shrinkage yarn and cotton yarn are used as weft yarn. Since the shrinkage of high shrinkage yarn is irreversible (i.e., one-time), by selecting high shrinkage yarn with a rated shrinkage rate, under specific conditions, the shrinkage rate of high shrinkage yarn is greater than that of cotton yarn. In this way, after being slit into strips, through the ironing process, the soft and non-melting cotton yarn will cover the hard edge of the high shrinkage yarn formed by hot cutting and melting, so as to achieve a soft and comfortable cutting edge effect, and further control the proportion of cotton yarn to ensure the bonding requirements; at the same time, due to the shrinkage difference between the high shrinkage yarn, cotton yarn and warp yarn, the cotton yarn passively shrinks and bends, and the obtained woven label feels softer and more comfortable, so that the soft woven label can have both good appearance and soft feel without raveling.

[0010] In some embodiments, the high shrinkage yarn satisfies at least one of the conditions (a) to (c):

[0011] (a) The high shrinkage of the high shrinkage yarn in boiling water is: 20% to 50%;

[0012] The shrinkage rate of the high shrinkage yarn is further regulated to further improve the soft feel of the soft woven label.

[0013] (b) the high shrinkage yarn comprises at least one of polyester and nylon;

[0014] (c) The high shrinkage yarn is white.

[0015] In some embodiments, the low-elastic polyester yarn satisfies at least one of the conditions (d) to (e):

[0016] (d) the low-elastic polyester yarn is DTY low-elastic polyester yarn;

[0017] (e) The low-elastic polyester yarn is a colored low-elastic polyester yarn.

[0018] In some embodiments, the cotton yarn satisfies at least one of the conditions (f) to (g):

[0019] (f) the cotton yarn is colored cotton yarn;

[0020] (g) Under the same conditions, the shrinkage rate of the cotton yarn is less than the shrinkage rate of the high shrinkage yarn.

[0021] Using colored cotton yarn and white high shrinkage yarn as weft and colored low-elastic polyester yarn as warp, pattern tissues of different colors or jacquard color structures are obtained.

[0022] Another aspect of the present invention provides a method for preparing a soft woven label, comprising the following steps:

[0023] (1) Yarn selection: providing weft yarn and warp yarn, wherein the weft yarn includes high shrinkage yarn and cotton yarn, the warp yarn includes low-elastic polyester yarn, and the mass proportion of the cotton yarn in the weft yarn is ≤45%; the shrinkage rate of the high shrinkage yarn in boiling water is ≥15%, and the shrinkage rate of the low-elastic polyester yarn in boiling water is ≤1%;

[0024] (2) Woven label edge lock design: the cotton yarn in the weft yarn is moved to the upper layer of the woven label edge lock area, and the high shrinkage yarn is moved to the middle and lower layers of the woven label edge lock area, and the pattern of the woven label edge lock area is designed;

[0025] (3) Woven label weaving: the warp yarn is drawn into a warp yarn head, and the warp yarn and the weft yarn are used for weaving to prepare a woven label cloth;

[0026] (4) Cutting and slitting: cutting and slitting along the edge-locking area of ​​the woven label cloth to obtain a prefabricated woven label;

[0027] (5) Post-finishing: placing the prefabricated woven label in a treatment liquid for immersion treatment to prepare a liquid-coated prefabricated woven label; the treatment liquid includes water or a resin finishing agent compound liquid;

[0028] The liquid-carrying prefabricated woven label is ironed and dried to prepare a soft woven label.

[0029] In the above-mentioned soft woven label, high shrinkage yarn and cotton yarn are used as weft yarn. Since the shrinkage of high shrinkage yarn is irreversible (i.e., one-time), by selecting high shrinkage yarn with a rated shrinkage rate, under specific conditions, the shrinkage rate of high shrinkage yarn is greater than that of cotton yarn. In this way, after being slit into strips, through the ironing process, the soft and non-melting cotton yarn will cover the hard edge of the high shrinkage yarn formed by hot cutting and melting, so as to achieve a soft and comfortable cutting edge effect, and further control the proportion of cotton yarn to ensure the bonding requirements; at the same time, due to the shrinkage difference between the high shrinkage yarn, cotton yarn and warp yarn, the cotton yarn passively shrinks and bends, and the obtained woven label feels softer and more comfortable, so that the soft woven label can have both good appearance and soft feel without raveling.

[0030] In some of the embodiments, in step (3), the hot stamping temperature of the weaving step is 120°C to 165°C.

[0031] By adjusting the hot stamping temperature during weaving, the shrinkage rate of each yarn in the weft and warp can be controlled so that the shrinkage rate of the cotton yarn is less than the shrinkage rate of the high-shrinkage yarn, thereby further improving the softness.

[0032] In some embodiments, in step (4), the step of cutting into strips is performed using an ultrasonic slitting machine.

[0033] Cutting with an ultrasonic slitter can further improve the appearance and soft feel.

[0034] In some embodiments, step (5) further includes the following steps:

[0035] The prefabricated woven label is immersed in a treatment liquid to prepare a liquid-coated prefabricated woven label; the treatment liquid includes water or a resin finishing agent compound liquid;

[0036] The soft woven label after ironing and drying is cut and folded.

[0037] In some embodiments, the treatment liquid is a resin finishing agent compound liquid, which includes, by weight: 45 to 55 parts of formaldehyde-free resin, 45 to 55 parts of MgCl2, 1 to 2 parts of acetic acid; 50 parts of hydrophilic microemulsion softener, 1 part of penetrant and 850 parts of water;

[0038] The immersion temperature is 60°C to 100°C;

[0039] The liquid-carrying rate of the liquid-carrying prefabricated woven label is 70% to 150%.

[0040] By adjusting the finishing conditions, the appearance and soft feel can be further improved.

[0041] In some embodiments, the temperature of the ironing and drying step is 130° C. to 160° C., and the ironing time is 20 seconds to 60 seconds. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are provided. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] The present invention provides a soft woven label, which uses high shrinkage yarn and cotton yarn as weft yarn and low elastic polyester yarn as warp yarn, and the mass proportion of cotton yarn in the weft yarn is ≤45%;

[0047] Among them, the shrinkage rate of high shrinkage yarn in boiling water is ≥15%, and the shrinkage rate of low-elastic polyester yarn in boiling water is ≤1%.

[0048] In the above-mentioned soft woven label, high shrinkage yarn and cotton yarn are used as weft yarn. Since the shrinkage of high shrinkage yarn is irreversible (i.e., one-time), by selecting high shrinkage yarn with a rated shrinkage rate, under specific conditions, the shrinkage rate of high shrinkage yarn is greater than that of cotton yarn. In this way, after being slit into strips, through the ironing process, the soft and non-melting cotton yarn will cover the hard edge of the high shrinkage yarn formed by hot cutting and melting, so as to achieve a soft and comfortable cutting edge effect, and further control the proportion of cotton yarn to ensure the bonding requirements; at the same time, due to the shrinkage difference between the high shrinkage yarn, cotton yarn and warp yarn, the cotton yarn passively shrinks and bends, and the obtained woven label feels softer and more comfortable, so that the soft woven label can have both good appearance and soft feel without raveling.

[0049] It is understood that the above-mentioned boiling water shrinkage refers to the boiling water shrinkage under normal pressure, which is a standard atmospheric pressure, which is 1013.25 kPa. The above-mentioned "the mass proportion of the cotton yarn in the weft yarn is ≤45%" means "the mass proportion of the cotton yarn in the weft yarn is greater than 0 and ≤45%".

[0050] In some embodiments, the high shrinkage of the high shrinkage yarn in boiling water is 20% to 50%.

[0051] The high shrinkage yarn is further regulated to further improve the soft feel of the soft woven label.

[0052] It should be noted that when a numerical range is disclosed herein, the above range is considered continuous and includes the minimum and maximum values ​​of the range, and every value between such minimum and maximum values.

[0053] For example, “20%-50%” includes but is not limited to: 20%, 25%, 30%, 35%, 40%, 45%, 50% and a range consisting of any two values.

[0054] In some of these embodiments, the high shrinkage yarn includes at least one of polyester and nylon.

[0055] In some embodiments, the high shrinkage yarn includes polyester, nylon, or a composite yarn of polyester and nylon.

[0056] In some of these embodiments, the high shrinkage yarn is white.

[0057] In some embodiments, the mass proportion of the cotton yarn in the weft yarn is 10% to 45%.

[0058] In some embodiments, the mass proportion of the cotton yarn in the weft yarn is 20% to 45%.

[0059] “10%-45%” includes but is not limited to: 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% and a range consisting of any two values.

[0060] In some of the embodiments, under the same conditions, the shrinkage of the cotton yarn is less than the shrinkage of the high shrinkage yarn.

[0061] It should be noted that the above-mentioned same conditions refer to the same processing and weaving conditions or testing conditions.

[0062] In some of these embodiments, the cotton yarn is colored cotton yarn.

[0063] It can be understood that colored cotton yarn refers to colored yarn that has been dyed on the basis of white cotton yarn, and its color can be any color except white, including but not limited to: red, orange, yellow, green, cyan, blue, and purple.

[0064] In some of the embodiments, the cotton yarn may be natural cotton yarn or artificial cotton yarn such as cotton staple fiber; further, it may be pure cotton yarn or pure cotton yarn with a cotton content of 75% or more.

[0065] In some embodiments, the low-elastic polyester yarn is DTY low-elastic polyester yarn.

[0066] DTY low-stretch polyester yarn is a yarn made of polyester low-stretch yarn. Polyester low-stretch yarn (Draw texturing yarn, referred to as DTY) is a type of textured yarn of polyester chemical fiber. It is made of polyester chips (PET) as raw materials, using high-speed spinning of polyester pre-oriented yarn (POY), and then processed by drawing and false twisting.

[0067] In some embodiments, the low-elastic polyester yarn is a colored low-elastic polyester yarn.

[0068] Similarly, colored low-elastic polyester yarn refers to colored yarn that has been dyed based on natural low-elastic polyester yarn. Its color can be any color except the natural color, including but not limited to: red, orange, yellow, green, cyan, blue, and purple.

[0069] Using colored cotton yarn and white high shrinkage yarn as weft and colored low-elastic polyester yarn as warp, pattern tissues of different colors or jacquard color structures are obtained.

[0070] Another aspect of the present invention provides a method for preparing a soft woven label, comprising the following steps (1) to (5).

[0071] (1) Yarn selection: Weft yarn and warp yarn are provided. The weft yarn includes high shrinkage yarn and cotton yarn, and the warp yarn includes low-elastic polyester yarn, and the mass proportion of cotton yarn in the weft yarn is ≤45%; the shrinkage rate of high shrinkage yarn in boiling water is ≥15%, and the shrinkage rate of low-elastic polyester yarn in boiling water is ≤1%;

[0072] (2) Woven label edge design: The cotton yarn in the weft yarn is moved to the upper layer of the woven label edge area, and the high shrinkage yarn is moved to the middle and lower layers of the woven label edge area, and the pattern of the woven label edge area is designed.

[0073] The pattern of the label edge area can be designed according to specific needs.

[0074] The side with the pattern is the front side, and the opposite side is the back side. The visible yarn on the front side is called the upper layer, the yarn visible on the back side is the lower layer, and the yarn that cannot be seen on both the front and back sides is called the middle layer.

[0075] (3) Woven label weaving: The warp yarn is pulled into a warp yarn head, and the warp yarn and the weft yarn are used for weaving to prepare the woven label cloth.

[0076] By weaving warp yarn and weft yarn, different woven fabrics can be woven according to needs, such as jacquard fabrics. Specifically, colored cotton yarn and white high-shrinkage yarn are used as weft yarn, and colored low-elastic polyester yarn is used as warp yarn to obtain pattern tissues of different colors or jacquard color structures.

[0077] In a specific example, a jacquard structure is obtained by using blue cotton yarn and white high shrinkage yarn as weft and black low-elastic polyester yarn as warp.

[0078] (4) Cutting and slitting: Cutting and slitting along the edge lock area of ​​the woven label to obtain a prefabricated woven label.

[0079] (5) Post-finishing: placing the prefabricated woven label in a treatment liquid for immersion treatment to prepare a liquid-coated prefabricated woven label; the treatment liquid includes water or a resin finishing agent compound liquid;

[0080] The liquid prefabricated woven label is ironed and dried.

[0081] In the preparation method of the soft woven label, high shrinkage yarn and cotton yarn are selected as weft yarn. Since the shrinkage of high shrinkage yarn is irreversible (i.e., one-time), by selecting high shrinkage yarn with a specific shrinkage rate, under specific conditions, combined with a suitable finishing process, the shrinkage rate of the high shrinkage yarn is made greater than that of the cotton yarn. In this way, after the strips are cut, through the ironing process, the soft and non-melting cotton yarn will cover the hard edge of the high shrinkage yarn formed by hot cutting and melting, so as to achieve a soft and comfortable cutting effect, and further control the proportion of cotton yarn to ensure the bonding requirements; at the same time, due to the shrinkage difference between the high shrinkage yarn and the cotton yarn and the warp yarn, the cotton yarn passively shrinks and bends, and the obtained woven label feels softer and more comfortable, so that the soft woven label can have both good appearance and soft feel without raveling.

[0082] In some of the embodiments, in step (3), the hot stamping temperature of the weaving step is 120°C to 165°C.

[0083] In some of the embodiments, in step (3), the hot stamping temperature of the weaving step is 150°C to 155°C.

[0084] By adjusting the hot plate temperature during weaving, the shrinkage rate of each yarn in the weft and warp can be controlled to ensure that the shrinkage rate of cotton yarn is less than that of high-shrinkage yarn, so as to further improve softness.

[0085] In some of the embodiments, in step (4), the step of cutting into strips is performed using an ultrasonic slitting machine.

[0086] Cutting with an ultrasonic slitter can further improve the appearance and soft feel.

[0087] In some embodiments, step (5) further includes the following steps:

[0088] The post-processing step comprises the following steps:

[0089] The soft woven label after ironing and drying is cut and folded.

[0090] In some of the embodiments, the soaking treatment step is repeated multiple times; specifically, the soaking treatment step is repeated 2 to 3 times.

[0091] In one specific example, the immersion treatment step is repeated 3 times.

[0092] In some of the embodiments, the treatment liquid is a resin finishing agent compound liquid, which includes, by weight: 20 to 55 parts of formaldehyde-free resin, 25 to 55 parts of MgCl2, 1 to 2 parts of acetic acid; 50 parts of hydrophilic microemulsion softener, 1 part of penetrant and 850 parts of water.

[0093] In some of the embodiments, the treatment liquid is a resin finishing agent compound liquid, which includes, by weight: 45 to 55 parts of formaldehyde-free resin, 45 to 55 parts of MgCl2, 1 to 2 parts of acetic acid; 50 parts of hydrophilic microemulsion softener, 1 part of penetrant and 850 parts of water.

[0094] By adjusting the finishing conditions, the appearance and soft feel can be further improved.

[0095] In some of these embodiments, the formaldehyde-free resin is Arkofix NZW LIQ resin and / or Arkofix NZK LIQ pre-catalyzed resin.

[0096] In some embodiments, the hydrophilic microemulsion softener is a cationic hydrophilic microemulsion softener. Specifically, the hydrophilic microemulsion softener includes SILYOUWET.

[0097] In some embodiments, the penetrant is a FKS penetrant.

[0098] The full name of penetrant FKS is fatty alcohol polyoxyethylene ether, which is a non-ionic surfactant.

[0099] In some embodiments, the immersion treatment temperature is 60°C to 100°C.

[0100] In some embodiments, the liquid impregnation rate of the liquid impregnated prefabricated woven label is 70% to 150%.

[0101] Liquid pick-up rate = (fabric weight after soaking - fabric weight before soaking) / fabric weight before soaking × 100%.

[0102] In some embodiments, the temperature of the ironing and drying step is 130° C. to 160° C., and the time of the ironing roller is 20 seconds to 60 seconds.

[0103] In some embodiments, the cutting and folding step specifically includes: folding two ends of the woven label in half and cutting and folding the woven label into pieces.

[0104] The present invention will be described below in conjunction with specific embodiments, but the present invention is not limited to the following embodiments. It should be understood that the attached claims summarize the scope of the present invention.
