Description

Technical Field

[0001] This invention belongs to the field of wig manufacturing technology, specifically relating to a lightweight and comfortable hairpiece and its manufacturing method. Background Technology

[0002] Hair bangs, as a common hair styling product, are widely used in hair decoration, hair repair, and other scenarios. Traditional hair bangs are mainly divided into two categories: machine-made hair bangs and hand-braided hair bangs. Machine-made hair bangs are made through multiple sewing processes, which is more efficient than hand-braided hair bangs, but they have problems such as uneven thickness, poor invisibility when worn, and low comfort. Hand-braided hair bangs are made by hand-weaving, which has certain advantages in terms of wearing quality, but the production process is time-consuming and labor-intensive, and hair loss is very likely after cutting and segmenting, which seriously affects the user experience.

[0003] Currently, there is no existing technology that can simultaneously solve the problems of poor wearing experience of machine-made hair flaps, easy hair loss in hand-woven hair flaps, and low production efficiency in hair flap manufacturing. Therefore, developing a hair flap that balances production efficiency, wearing comfort, invisibility, and hair loss prevention, as well as its manufacturing method, has significant practical application value. Summary of the Invention

[0004] Based on the above technical background, the main objective of this invention is to provide a lightweight and comfortable hair fringe and its preparation method, so as to overcome the shortcomings of the prior art.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this invention includes: The first aspect of this invention is to provide a method for preparing a lightweight and comfortable hairpiece, the method comprising the following steps: Step 1: Select the appropriate real human hair material according to the customization requirements; Step 2: Select different length options according to your customization requirements; Step 3: According to the required amplitude standard of the customization requirements, remove the hairs with poor hair quality from the wig, measure and calibrate whether the amplitude matches the customization requirements, and then measure and weigh the wig according to the customization requirements. Step 4: After weighing the wig, iron it flat, then sew the wig with double needles, and stick the sewn wig to the glass plate to fix it. Apply glue to the front of the top of the fixed hairpiece, and then apply glue to the back of the top of the hairpiece. Step 5: After drying, the hairpiece undergoes post-processing, including drying, trimming, ironing, weighing, trimming, and packaging.

[0006] The steps described above are described in detail below.

[0007] In step 2, select different length options according to the customization requirements. Common lengths range from 6 inches to 30 inches.

[0008] In step 3, the standard condition for the proportion range is that the proportion of common hair range in this range is 2 to 10%.

[0009] The standard condition for the proportion range is that the common hair range accounts for 3% of this range.

[0010] This range indicates the range for the longest hair in the custom-made wig.

[0011] The weight of the wig is measured and weighed according to the customization requirements. Common hair weights range from 1 g to 100 g. The weighed hair is then combed neatly.

[0012] In step 4, ironing the wig can prevent damage to the hair in subsequent processes.

[0013] The density of the double-needle sewing is 26 to 30 stitches per inch.

[0014] Preferably, the density of the double-needle sewing is 28 stitches per inch. This invention uses double-needle sewing to secure the wig.

[0015] Use masking tape to stick the product with the lines already set onto the glass plate, and fix the distance between the two lines evenly.

[0016] The method for applying adhesive to the top front of the hair fringe includes: applying one coat of anti-hair loss adhesive to the top front of the fixed hair fringe, then drying for 5-15 minutes, then applying two coats of anti-hair loss adhesive, drying for 5-15 minutes after application, and finally applying one coat of matte adhesive, and drying for 4-6 hours after application.

[0017] Preferably, apply one coat of anti-hair loss glue to the top front of the fixed hairline, then dry for 10 minutes, then apply two coats of anti-hair loss glue, dry for 10 minutes after application, and finally apply one coat of matte glue, and dry for 5 hours after application.

[0018] The method for applying adhesive to the reverse side of the top of the hair fringe includes: applying anti-hair loss glue twice to the reverse side of the top of the fixed hair fringe, then drying for 5 to 15 minutes, then applying one coat of matte glue, and drying for 4 to 6 hours after application.

[0019] Preferably, apply two coats of anti-hair loss glue to the reverse side of the top of the fixed hairline, then dry for 10 minutes, then apply one coat of matte glue, and dry for 5 hours after application.

[0020] The hair loss prevention glue is prepared by mixing Korean S-1070 glue, Korean S-1090 glue, Korean A-8006H glue, Korean CA-75 glue and methyl acetate in a mass ratio of (60-80):(20-40):(15-25):(10-15):(40-80).

[0021] Preferably, the anti-hair loss glue is obtained by mixing Korean S-1070 glue, Korean S-1090 glue, Korean A-8006H glue, Korean CA-75 glue and methyl acetate in a mass ratio of 70:30:20:12:60.

[0022] The matte adhesive is obtained by mixing Korean S-1070 adhesive, Korean S-1090 adhesive, methyl acetate and Japanese E-1009 polishing powder in a mass ratio of (60-80):(20-40):(40-100):(2-4).

[0023] Preferably, the matte adhesive is obtained by mixing Korean S-1070 adhesive, Korean S-1090 adhesive, methyl acetate and Japanese E-1009 gloss remover in a mass ratio of 70:30:70:3.

[0024] The drying temperature mentioned above is 45-50℃, preferably 45℃. If the baking temperature is too high (>50℃), the adhesive layer will easily become aging and brittle. If the baking time is too short (<12min), the curing will be incomplete. Both excessively high baking temperature and excessively short baking time will reduce the adhesive strength of the glue.

[0025] In step 5, the post-treatment includes: adding cold perm lotion and shampoo to warm water at 45-55°C, stirring well, soaking the dried hair strands in the solution for 10-20 minutes, then rinsing the hair strands 3-7 times with purified water at 40-50°C, and then soaking the rinsed hair strands in water containing conditioner for 10-20 minutes.

[0026] Preferably, the post-treatment includes: adding cold perm lotion and shampoo to warm water at 50°C, stirring evenly, soaking the dried hair strands in the solution for 15 minutes, then rinsing the hair strands five times with purified water at 45°C, and soaking the rinsed hair strands in water containing conditioner for 15 minutes.

[0027] The mass ratio of the cold perm lotion, shampoo, and warm water is (15-25):(5-15):1000.

[0028] Preferably, the mass ratio of the cold perm lotion, shampoo, and warm water is 20:10:1000.

[0029] The amount of cold perm lotion and shampoo used will affect the smoothness of the hair extensions. The cold perm lotion, shampoo and warm water are mixed in the above mass ratio. The cold perm lotion and shampoo can clean the impurities on the surface of the hair strands, so as to avoid the impurities affecting the bonding between the glue and the hair strands. At the same time, the conditioner can replenish the hair strands with nutrients, improve the hair strands’ flexibility, and reduce the breakage of the hair strands under stress. At the same time, the excessive amount of reagents will not weaken the adhesion between the glue layer and the hair strands due to residual ingredients. Ultimately, it achieves the dual reinforcement of “strong glue layer + hair strands’ breakage resistance”.

[0030] The mass ratio of the conditioner, water and hair extensions is (38-42):1000:(90-110).

[0031] Preferably, the mass ratio of the conditioner, water, and hairspray is 40:1000:100.

[0032] The above post-processing steps can replenish nutrients to the wig, making it smoother, more droopy, and drier.

[0033] The drying conditions are: drying at 40-50℃ for 550-600 min.

[0034] Preferably, the drying conditions are: drying at 45°C for 570 min.

[0035] The trimming includes cutting off the top edge of the hairpiece along the first line.

[0036] The ironing process includes: setting the iron to wool mode and ironing at 150-170°C until dry and smooth.

[0037] Preferably, the ironing includes: setting the iron to wool mode and ironing at 160°C until dry and smooth.

[0038] The weighing process includes: weighing and calibrating the finished hair curtain to confirm that the weight is correct.

[0039] The trimming includes: lightly trimming the hairline according to customized requirements.

[0040] This invention enhances hair retention through "double-needle fixation + double-layer anti-hair loss hair gel," and controls the thickness and shine of the hairpiece using "thin glue layer + matte glue." Post-treatment processes further improve hair smoothness. The resulting hairpiece has a thickness of 0.8–1.5 mm and a shedding rate of ≤0.1% after cutting. This solves the problems of traditional machine-made hairpieces being heavy and hand-braided hairpieces being inefficient and prone to hair loss. The hairpiece preparation method described in this invention has the advantages of high production efficiency, convenient installation, and lightweight, invisible wear, making it suitable for hair styling and hair replacement applications.

[0041] A second aspect of the present invention is to provide a lightweight and comfortable hairpiece prepared by the method described in the first aspect of the present invention.

[0042] The beneficial effects of this invention are as follows: (1) Compared with hand-knitted hair curtains, the present invention replaces manual weaving with "double needle running in one go + glue curing", which greatly shortens the production cycle by more than 60% and does not require a large number of skilled weaving workers, thus reducing labor costs. Compared with traditional machine hair curtains that require multiple sewing processes, the preparation method described in the present invention simplifies the sewing process and increases production efficiency by more than 40%.

[0043] (2) The present invention uses the process of “double-line fixing + double-layer anti-hair loss hair gel” to make the hair strands less likely to fall out after the hair curtain is cut. The installer can cut it arbitrarily according to the wearer’s head circumference without additional reinforcement. The installation time is shortened to 1 / 3 of the traditional hand-braided hair curtain.

[0044] (3) The present invention uses a process of "thin adhesive layer + matte adhesive" to make the thickness of the hair flap only 1 / 2 of that of the traditional machine-made hair flap. The thickness of the hair flap in the present invention is 0.8 to 1.5 mm, the hair fixing strength is ≥5 N (single hair tensile test), and the hair loss rate after cutting is ≤0.2%. The hair flap is lightweight and burden-free when worn. The matte adhesive avoids hair reflection and has a significant invisible effect. In addition, the post-care process adopted in the present invention improves the smoothness and drape of the hair, making it more natural after wearing. Attached Figure Description

Weigh and calibrate the finished hair extensions after ironing to confirm the weight is correct. Lightly trim the hair extensions according to the customized requirements, and finally package the finished product. Experimental Example Experimental Example 1: Hair Strand Fixing Strength Test The hair strand fixing strength of the hair curtains prepared in Examples 1 to 3 were tested respectively, and the test standard was GB / T 3923.1-2013 "Textiles - Tensile Properties of Fabrics - Part 1: Determination of Breaking Strength and Elongation at Break (Strip Method)". The test results are shown in Table 1.

[0063] Table 1. Results of hair fixation strength test

[0064] As can be seen from Table 1, the single hair strand fixing strength of the hair curtains prepared in Examples 1 to 3 is 5.5 to 6.2 N, all ≥ 5 N, and the minimum fixing strength of the bundled hair strands (10 strands per bundle) is 52.3 to 58.5 N, indicating that the hair curtains prepared according to the preparation method of the present invention have high hair strand fixing strength and are not easy to fall off.

[0065] Experiment Example 2: Hair Loss Rate Test After Cutting Hair loss rate tests were conducted on the hairpieces prepared in Examples 1-3. The test procedure was as follows: A standard sample of 10cm × 5cm (length × width) was cut from each of the finished hairpieces prepared in Examples 1-3, and the cutting position was uniformly in the middle of the hairpiece (avoiding the edge cutting loss area) to ensure that the initial number of hair strands and the distribution of the adhesive layer were consistent for each sample. Simultaneously, the initial weight of each sample (denoted as M0) was recorded using an electronic balance with an accuracy of 0.001g to avoid interference from loose fibers (before weighing, gently wipe away any loose fibers from the sample surface with a lint-free cloth; the weight of loose fibers is not included in the initial weight). Using prepared stainless steel scissors, a straight cut was made 1cm outside the top sewing line of the sample (the cutting direction was perpendicular to the direction of the hair strands). The cutting force should be uniform (controlling the cutting speed to 2cm / s) to avoid damage to the adhesive layer and additional hair loss due to forceful cutting. The lint-free paper containing the detached hair (including the detached hair) was weighed in an electronic balance with an accuracy of 0.001g and recorded as m1. The actual weight of the detached hair (M1) was calculated using the formula: M1 = m1 - m0 (subtracting the weight of the lint-free paper itself; the weight of the white lint-free paper is recorded as m0). Based on the initial sample weight and the weight of the detached hair, the hair loss rate (referred to as R) for each sample was calculated.

[0066] The formula for calculating hair loss rate is as follows: R = (M1 / M0) × 100%.

[0067] Where M1 is the actual weight of the shed hair and M0 is the initial weight of the sample. The test results are shown in Table 2.

[0068] Table 2 Hair shedding rate test

[0069] As can be seen from Table 2, the hair loss rate of the hair curtains prepared in Examples 1 to 3 is 0% to 0.2%, and the hair loss rate is ≤0.2%, indicating that the hair loss rate of the hair curtains prepared according to the preparation method of the present invention is low.
