Description

Technical Field

[0001] The present invention relates to the field of super fiber labels, in particular to the field of D04H1 / 00, and more specifically to a super fiber label and a preparation method thereof. Background Art

[0002] Microfiber is thinner than traditional fiber, so it has a more fluffy and soft touch than ordinary fiber, and can overcome the shortcomings of natural fiber that is easy to wrinkle and artificial fiber that is not breathable. In addition, it also has many irreplaceable excellent properties such as warmth retention, no mold, no insects, light weight, waterproof and even water absorption.

[0003] The patent with publication number 201921975135.4 discloses a protective cover that integrates multi-color silicone, microfiber and plastic shell. The prepared protective cover is highly manufacturable and can be combined with various three-dimensional complicated patterns, which greatly improves the sensory grade. However, over time, the silicone will fall off the surface of the protective cover, affecting the feel and aesthetics of the protective cover.

[0004] The patent with publication number CN201410315605.X discloses a condensed printing silica gel, preparation method and application. The floral silica gel can be printed on common fabrics such as cotton, lycra, microfiber, canvas, nylon, some waterproof nylon, some PU fabrics and leather. However, in the washing test, some floral silica gel will fall off from the surface of the fabric, which is not conducive to long-term use.

[0005] At present, microfiber materials have also been widely used in the manufacture of clothing labels. Microfiber labels are generally made of microfiber substrate and silica gel through a lamination process. However, the microfiber labels on the market generally have poor friction resistance, silica gel easily falls off from the substrate, and microfiber labels will fade and stain after washing, which seriously affects the quality and user experience of microfiber labels. Summary of the invention

[0006] In order to solve the above technical problems, the first aspect of the present invention provides a super fiber label, the raw materials for preparing the super fiber label at least include: a base material, and silica gel for logo. In the present invention, logo means a trademark.

[0007] Preferably, the substrate is an ultra-fiber substrate; the raw materials for preparing the silica gel for the logo include a hardener, a colorant, and silica gel.

[0008] Preferably, the raw materials for preparing the logo include, by weight: 8-15 parts of silica gel and 0.5-2 parts of hardener.

[0009] Preferably, the silica gel and the hardener are both in liquid state.

[0010] Preferably, the colorant is 5-20% by weight of the hardener.

[0011] Further preferably, the colorant accounts for 10% of the weight of the hardener.

[0012] Further preferably, the silica gel comprises 10 parts, the hardener comprises 1 part, and the colorant comprises 0.1 part.

[0013] Preferably, the substrate specification is 0.6-1.0MM.

[0014] Further preferably, the substrate has a specification of 0.8MM and a size of 5×10cm.

[0015] Preferably, the hardener is an organosilicon hardener.

[0016] Further preferably, the hardener is of model KD1380-40-B.

[0017] In order to improve the water-washing resistance of the microfiber label, the inventor creatively discovered that the use of KD1380-40-B hardener can improve the water-washing resistance of the microfiber label and improve the toughness of the silica gel used for the logo. The applicant speculates that the KD1380-40-B hardener can efficiently bond with the polyurethane resin on the surface of the microfiber substrate under high temperature pressing conditions, and KD1380-40-B can undergo efficient cross-linking polymerization reaction with the silica gel, thereby improving the toughness of the silica gel used for the logo and making the microfiber label more water-washable.

[0018] Preferably, the silica gel is a mixed silica gel.

[0019] Further preferably, the silica gel model is KD1380-40-A.

[0020] Preferably, the colorant has a specification of 100-500 mesh.

[0021] Further preferably, the colorant has a specification of 100 mesh.

[0022] The second aspect of the present invention provides a method for preparing a superfiber label, the steps comprising at least:

[0023] S1. Mixing silica gel, a hardener and a colorant to obtain silica gel for a logo, and using a pressing machine to press the silica gel for a logo onto a substrate to obtain a mold;

[0024] S2. The mold prepared in step S1 is subjected to a cooling process to prepare a superfiber label.

[0025] Preferably, the pressing temperature of the pressing machine is 150-180°C.

[0026] Further preferably, the pressing temperature of the pressing machine is 160°C.

[0027] In order to improve the water-resistant performance of the microfiber label, the inventors found that when the pressing temperature during the preparation of the microfiber label is 150-180°C, excellent water-resistant performance can be obtained. The inventors speculate that: when the pressing temperature is higher than 180°C, the microfiber substrate is easily deformed by heat at high temperature, affecting the use effect of the microfiber label; when the pressing temperature is lower than 150°C, the adhesion viscosity between the silica gel for the logo and the microfiber substrate is not enough, and the silica gel for the logo is easy to fall off under the action of external force. When the pressing temperature is maintained at 150-180°C, the adhesion strength between the silica gel for the logo and the microfiber substrate can be guaranteed, and the microfiber substrate will not be deformed at the same time.

[0028] Preferably, the pressing time of the pressing machine is 30-90s.

[0029] Further preferably, the pressing time of the pressing machine is 60s.

[0030] Preferably, the cooling mold treatment temperature is -20 to 0°C.

[0031] More preferably, the cooling mold treatment temperature is -15°C.

[0032] Preferably, the cooling mold treatment time is 20-60s.

[0033] Further preferably, the cooling mold treatment time is 30s.

[0034] Beneficial effects:

[0035] (i) In the present invention, by adding the hardener KD1380-40-B to the silica gel for logo, the liquid silica gel for logo can be firmly attached to the microfiber substrate after being mixed with the silica gel for logo by the pressing machine, and the friction resistance of the microfiber label is improved, and the silica gel for logo will not fall off from the microfiber substrate as time goes by.

[0036] (ii) In the present invention, the substrate used is an ultra-fine fiber substrate, which has good high temperature resistance. When the silica gel is printed on the ultra-fine fiber substrate at high temperature in a pressing machine, the ultra-fine fiber substrate will not melt, deform, or denature, and the ultra-fine fiber substrate will not fade after washing, and has excellent water washing resistance.

[0037] (III) In the present invention, by subjecting the pressed mold to a cooling treatment for 30 seconds at a temperature of -15°C, the logo can be qualitatively hardened with silica gel, effectively adhered to the surface of the microfiber substrate, not easily oxidized and not easily fallen off under water washing conditions.

[0038] (IV) In the present invention, when the working temperature of the pressing machine is 150-180°C, the ultra-fiber label obtained by pressing at this temperature has excellent water-washing resistance. BRIEF DESCRIPTION OF THE DRAWINGS
