Description

Technical Field

[0001] The invention relates to the technical field of clothing, in particular to a seamless gluing process for high-quality knitted shirt collars. Background Art

[0002] Knitted shirts are an increasingly popular style of shirt. Their skin-friendly feel and fabric stretch make them far more comfortable than regular shirts, making them popular and sought-after. However, the manufacturing process for high-quality knitted shirts is challenging, especially when it comes to the treatment of the placket and collar. First, knitted fabrics are highly elastic, requiring careful attention to the collar and placket, which are resistant to deformation. Second, the collar and placket of high-quality knitted shirts must be glued. Existing knitted shirts often have a poorly glued finish and are prone to degumming and deformation after repeated washing and wearing. Summary of the Invention

[0003] In view of the above problems, the present invention discloses a seamless gluing process for a knitted shirt collar to overcome the above problems or at least partially solve the above problems.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A seamless laminating process for knitted shirt collars, using the following materials:

[0006] Knitted fabrics, elastic double-sided tape, non-elastic single-sided tape;

[0007] The non-elastic single-sided adhesive strip is compacted with the elastic double-sided adhesive strip on its non-adhesive side using a high-temperature machine, the adhesive side of the non-elastic single-sided adhesive strip is compacted with the knitted fabric using a high-temperature machine, and the elastic double-sided adhesive strip is compacted with the knitted fabric using a high-temperature press.

[0008] Preferably, it specifically includes the following steps:

[0009] Step 1: Align the non-glue side of the non-elastic single-sided adhesive strip with one side of the elastic double-sided adhesive strip, and compact them through the high-temperature press to compound them together.

[0010] Step 2: Align the composite film obtained by compounding the elastic double-sided adhesive strip and the non-elastic single-sided adhesive strip with the collar surface clean plate, and cut off the excess adhesive surface so that the size of the composite film is consistent with the collar surface clean plate size.

[0011] Step 3: Compacting the adhesive side of the non-elastic single-sided adhesive strip in the processed composite film with the reverse side of the knitted fabric using a high-temperature machine.

[0012] Step 4: Place the front of the compacted knitted fabrics on the front side, sew the sides of the collar corners with a sewing machine, and cut the seam allowance to 0.15cm-0.2cm. After sewing the knitted fabrics, fold them over so that the side where the composite film is pressed is on the back side of the knitted fabrics, and compact them with the high-temperature press. Note that when using the press, the front side where the composite film is pressed should face down, and the side not pressed should face up.

[0013] Step 5: Cut off excess fabric according to the collar clean pattern.

[0014] Preferably, the knitted fabric is only one piece of fabric.

[0015] Preferably, the size of the non-elastic single-sided adhesive strip is 0.5 to 1.5 cm for the net seam of the collar surface, and the size of the elastic double-sided adhesive strip is 0.5 to 1.5 cm for the net seam of the collar surface.

[0016] As can be seen, the present invention's process improves the collar's shape retention by using a non-elastic, single-sided adhesive strip. After laminating the two films, the clean, cut surface is aligned with the collar surface, ensuring that the composite film is the same size as the collar surface. The non-deformable nature of the non-elastic, single-sided adhesive strip ensures that the composite film will not deform. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] To make the objectives, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The non-elastic single-sided adhesive strip adopts non-elastic hot-melt film, preferably Yingtong TY2227 hot-melt film (non-elastic), and the size is 0.5 to 1.5 cm for the net seam of the collar surface. The elastic double-sided adhesive strip adopts elastic hot-melt film, preferably Yingtong TY3301 hot-melt film (elastic), and the size is 0.5 to 1.5 cm for the net seam of the collar surface. The collar fabric is a high-elastic knitted fabric for shirts.

[0037] The back of the non-elastic single-sided tape is compacted with the elastic double-sided tape using a high-temperature press, the front of the non-elastic single-sided tape is compacted with the knitted fabric using a high-temperature press, and the elastic double-sided tape is compacted with the knitted fabric using a high-temperature press. The knitted fabric is preferably a high-elastic knitted fabric.

[0038] Example 1

[0039] Step 1: See Figure 6 , align the non-glue side of the non-elastic single-sided tape (i.e. the back of the non-elastic single-sided tape) with one side of the elastic double-sided tape, and compact them through a high-temperature press to bond the two hot-melt films together.

[0040] Step 2: See Figure 7 , align the composite film obtained by compounding the elastic double-sided tape and the non-elastic single-sided tape (in the figure below, the non-elastic single-sided tape is stacked under the (elastic) double-sided tape) with the collar clean plate, and cut off the excess tape surface.

[0041] Step 3: See Figure 8 The adhesive side of the non-elastic single-sided adhesive strip in the processed composite film is compacted with the reverse side of the high-elastic knitted fabric using a high-temperature machine.

[0042] Step 4: See Figure 9 , align the front sides of the knitted fabrics with the glue strips together, sew the sides of the collar corners with a sewing machine, and cut the seam allowance to 0.15cm~0.2cm (the blue part in the figure below is the seam allowance; in addition, cutting the seam allowance to 0.15cm~0.2cm means that there is 0.15cm~0.2cm left after cutting the seam allowance), fold the knitted fabrics after sewing them together, so that the side where the composite film is pressed is aligned with the back side of the knitted fabric, and press them with the high-temperature machine. Note that when using the press, the front side of the composite film pressed should face down and the side not glued should face up.

[0043] After the seams are cut, the collar is turned over to expose the front of the knitted fabric and the reverse side of the tape is pressed to become the inner side, that is, the side of the laminated film is pressed against the reverse side of the knitted fabric to obtain Figure 10 Item shown.

[0044] When using the press, the laminated film should be placed with the pressed side facing downwards and the unpressed side facing upwards (this can reduce the pressure marks on the seam edges).

[0045] Step 5: See Figure 11 , refer to the clean version of the collar and cut off the excess fabric at the bottom.

[0046] Comparative Example 1 (traditional turning and pressing process)

[0047] Materials: Collar panel (the collar panel is made by adding a 1cm seam allowance to the collar clean panel), collar clean panel, 15cm wide and 45cm long double-sided tape, knitted fabric. Figures 12-14 :

[0048] 1. Cut the knitted fabric according to the collar surface plate to obtain the collar surface fabric, and cut the double-sided tape according to the collar net plate to obtain the collar tape.

[0049] 2. Lay the collar tape on the reverse side of the knitted fabric and press it with a high-temperature press. Then cut and press the composite fabric according to the collar clean plate to obtain the collar lining.

[0050] 3. Stick the 1cm wide double-sided tape to the 1cm seam of the collar.

[0051] 4. First, glue the adhesive strip side of the collar lining to the reverse side of the collar fabric at low temperature. Then, fold the seam of the collar surface over the front side of the collar lining and press and glue them together using a high-temperature press. This will create a collar with a folded surface.

[0052] Comparative Example 2 (Traditional Seam Laminating Process)

[0053] Materials: Collar panel (the collar panel is made by adding a 1cm seam allowance to the collar clean panel), collar clean panel, 15cm wide and 45cm long double-sided tape, knitted fabric. Figures 15-18 :

[0054] 1. Cut the knitted fabric according to the collar pattern to obtain the collar face fabric and collar lining. Fold a 15 cm wide by 45 cm long double-sided adhesive strip in half and press it to obtain a double-layer double-sided adhesive strip composite film. Cut the composite film according to the collar clean pattern to obtain the collar adhesive strip.

[0055] 2. Stick the collar tape to the back of the collar fabric and press it with a high-temperature press.

[0056] 3. Align the front of the collar fabric with the front of the collar lining, sew the seams between the collar edge and the collar corner, and trim the seams to 0.1cm-0.2cm.

[0057] 4. After the seams have been cut, the collar is turned over so that the front of the knitted fabric is exposed and the back of the tape becomes the lining. This means that the tape is pressed against the back of the collar lining. After pressing in a high-temperature press, the seam-seamed collar is obtained.

[0058] By comparing the effect diagram of the process of Example 1 with the effect diagram of Comparative Examples 1 to 2 (traditional process) ( Figures 1 to 5 We can find that the traditional folding process splits the collar surface and the collar lining, and the collar surface wraps around the collar lining, resulting in a more obvious indentation on the front of the collar. At the same time, there is a clear glued seam on the back of the collar, and white edge offset easily appears at the glued area. The overall aesthetics of the collar is not good, and there is a risk of degumming when the seam is folded over the collar lining. The traditional patchwork collar surface is a split seam between the collar surface and the collar lining, leaving seam indentations around the outer circle of the collar surface. There is no glue inside the seam, and there is a gap that can move. There is a risk of blistering when the collar surface is glued.

[0059] This Example 1 utilizes only one piece of fabric. The collar and lining do not need to be separated, but can be directly folded and pressed. The folded edge is clean and smooth, leaving no seam marks, preventing issues such as seam indentation, white edges on the adhesive tape, and seam debonding. The excellent construction eliminates unnecessary seams. Furthermore, the collar and lining are folded integrally around the periphery, eliminating bubbling at the seam head. This further enhances the sophistication of the collar and lining, ensuring a smooth and aesthetically pleasing surface. Furthermore, the non-elastic hot-melt film enhances the collar's firmness. (Note: The lower the elongation, elongation, and deformation rate, the better; the higher the recovery rate, the better.)

[0063]

[0064] Comparing Tables 1 and 2, we find that under a 20N tensile force, the experimental data for the collar surface of Example 1 is comparable to that of the patchwork collar surface (Comparative Example 2), and all data points are improved compared to the pressed collar surface (Comparative Example 1). Under a 50N tensile force, Example 1 exhibits the best recovery and deformation rates. Although its maximum elongation is slightly greater (0.58mm) than that of the patchwork collar surface (Comparative Example 2), Example 1 exhibits the best overall performance.
