Description

Sewn product and application thereof

Technical Field

The invention relates to a sewn product and application thereof.

Background

For sewn products containing fillers, the problem of washing durability has been troubling. In order to solve this problem, patent document CN103097280A discloses a stuffed article in which a core yarn and an effect yarn that is opened to form a loop fiber are integrated, and long fiber wadding is doubled in at least one direction and sewn together with a cover cloth to be integrated with the cover cloth, and compared to a conventional short fiber wadding, the long fiber wadding does not have a phenomenon of being accumulated in a large area even after being washed many times, and therefore, a certain degree of bulkiness can be maintained, but a part of the long fiber wadding is entangled by washing with running water, and further, problems such as washing offset and deterioration in heat retaining property occur.

Also disclosed in patent document CN1067145994A is a method for stabilization and a garment comprising stabilized quilting insulation, which is to sew a plurality of quilting stitch lines after the bundle structure is uniformly distributed, the quilting stitch lines being orthogonal to the longitudinal axis of the bundle structure, the quilting stitch lines providing lateral as well as longitudinal stabilization of the bundle structure with uniform density. Quilting seam lines are generally horizontal, while the longitudinal axis of the bundle structure is vertical, but such sewing methods do not effectively solve the problems of washing offset, washing offset after washing of the sewn products, and reduced heat retaining properties.

Detailed Description

The sewing product comprises a surface layer fabric, an inner layer fabric and long fiber cotton of a core-sheath structure filled between the surface layer fabric and the inner layer fabric, wherein the arrangement direction of the long fiber cotton is crossed with the sewing direction of the fixed long fiber cotton in a non-perpendicular state.

The surface layer fabric and the inner layer fabric used in the present invention are not particularly limited, and may be woven fabric or knitted fabric. The fiber raw material can be chemical fiber or natural fiber. Can be properly selected according to different product requirements.

The long fiber cotton used in the present invention is composed of long fibers having a core-sheath structure. Under the action of the compressed air, the fiber bundle of the sheath yarn is separated into a plurality of single fibers, the single fibers form a three-dimensional multi-ring shape while passing through the fiber bundle of the core yarn to form cross points, and the cross points are not fixed fusion points and can freely move within a certain range. When the long cellucotton is extruded by external force and deformed, the cross point of the long cellucotton can generate certain displacement to absorb the external force, and the original shape is recovered after the external force is removed. In the fiber-forming polymer, the polyester fiber has relatively high Young modulus, and can endow long fiber cotton with good pressure resistance and recovery.

In the present invention, the arrangement direction of the long fiber cotton and the sewing direction of the fixed long fiber cotton are crossed in a non-perpendicular state. Under the condition of not influencing the heat preservation, the fixed length of the long fiber cotton quilt is lengthened, the free length of the long fiber cotton quilt is effectively controlled, and the slidable distance is reduced. That is, if the long fiber quilts are crossed perpendicularly, the fixed length of the long fiber quilts becomes relatively short, the free length thereof becomes relatively long, and the washing offset ratio becomes large. The sewing direction of the fixed long fiber cotton does not include the sewing direction of the periphery of the garment piece.

Note that if the acute angle of the included angle formed by intersecting the long fiber cotton quilt in the non-perpendicular state is less than 25 degrees, the fixed length of the long fiber cotton quilt is relatively long, and although the slippage of the long fiber cotton quilt can be limited to a certain extent, the bulkiness tends to be reduced. If the angle is more than 65 degrees, the distance for fixing the long fiber cotton quilt becomes relatively short, the free slip length becomes relatively long, and the possibility of displacement after washing becomes large, therefore, it is preferable that the angle is 25 degrees to 65 degrees.

In the invention, in the sewing direction, the sewing stitches are continuous or discontinuous. The continuous type may be a linear type, a W type, an S type, or the like, and the W type is preferable. The discontinuous type means that the sewing stitches are in an interval state.

Wherein, the straight line type means that the sewing stitch is a straight line. The W line type refers to the shape of a sewn stitch W and is formed by connecting a plurality of line segments, an angle exists between each line segment and each line segment, an angle vertex exists, and the angle is larger than 0 and smaller than 180 degrees. The S-shaped line refers to that the sewing stitch is in a curved shape and is connected by a plurality of line segments, angles are formed between the line segments, and the vertex is a smooth vertex. The traces may be parallel or non-parallel.

The sewing thread can be divided into three categories of natural fiber, synthetic fiber and mixed fiber sewing thread according to raw materials. In the present invention, ordinary polyester yarn, ordinary nylon yarn or spandex-containing elastic yarn is preferred.

In the invention, the long fiber cotton can be sewn with one or more of the surface layer fabric, the inner layer fabric and the textile except the surface layer fabric and the inner layer fabric. That is, the long fiber cotton of the present invention may be fixed only to the surface layer fabric or the inner layer fabric, may be fixed to both the surface layer fabric and the inner layer fabric, or may be fixed to the textile. The woven fabric may be woven fabric, knitted fabric, nonwoven fabric, or the like. The selection may be made as appropriate depending on the product requirements, and the nonwoven fabric is preferable. When the long fiber cotton is fixed on the textile fabric, the surface layer and the inner layer can be freely designed according to the requirement.

Preferably, the elongation of the long fiber cotton in the fiber axis direction is 1 to 200%. Within the range, the sewing product has certain motion following performance, does not block the body from stretching motion and the like in the motion process, and improves the motion effect. More preferably, the elongation is 10% to 80%. The elongation may be that of the long fiber cotton itself as the filler, or that of an elastic body attached to the end of the filler by an external force.

Preferably, the elongation of the surface layer fabric in the long fiber cotton direction is 1-200% and is less than the elongation of the long fiber cotton in the fiber axis direction. When the sewn product is used as clothing, if the long fiber cotton does not have certain elasticity under the condition that the elbow joint and the knee joint are large in bending, the long fiber cotton may have a tight feeling of foreign matters during movement, and the feeling is not very comfortable. And if the elongation of the surface fabric is smaller than that of the long fiber cotton, when the elbow joint or the knee joint is bent, the core yarn in the long fiber cotton cannot slide out of the seam due to bending.

Preferably, the elongation of the lining fabric in the long fiber cotton direction is 1-200% and is less than the elongation of the long fiber cotton in the fiber axis direction. When the sewn product is used as a sleeping bag, the sewn product can ensure that no obstacle feeling is generated during stretching, and the comfort is further improved. The elongation of the lining fabric is smaller than that of the long fiber cotton, so that the problem that core yarns in the long fiber cotton slide off from seams during stretching is avoided.

The sewn product of the invention may be a coat, pants, a vest, a coverall, a jacket, a quilt, a pillow, a sleeping bag, underwear, a pajama, a sweater, tights, socks, or a sportswear, etc.

The invention relates to a method for measuring various parameters, which comprises the following steps:

(1) rate of displacement in width direction after washing of filler

④ printing a photo, and distinguishing a long fiber cotton area W2 and a non-long fiber cotton area W1 in the cut area on the photo;

⑤ areas with and without long staple fibres were cut and weighed separately.

⑥, the shift rate after washing is = W1/(W1 + W2) × 100%.

(2) Appearance evaluation

The degree of shift change of the filler is observed under a D65 light source, and is divided into four types of ultra-slight, serious and ultra-serious, wherein ultra-slight, i.e. basically no shift is represented by '◎', slight, i.e. slight shift is represented by '○', serious, i.e. obvious shift is represented by '△', and ultra-serious, i.e. especially obvious shift is represented by 'x'.

(3) Elongation of surface layer fabric and lining fabric

Measured according to JIS L1096-2010.

(4) Thermal insulating property of Crohn's value

Determined according to the KES method.

(5) Elongation of long fiber cotton in the length direction

The long cellucotton is in a natural placing state, and a section of the long cellucotton with the length of 10cm is cut to be used as a sample to be detected. The sample to be tested is pulled to be in a straight state under the tension of 0.1g/dtex, and the length e is measured, and the elongation of the long fiber cotton is = (e-10)/10 × 100%.

(6) Thickness retention ratio

① folding the sewn product with side length of 50cm into triangle along diagonal line, and placing on table;

② placing a 20cm side length square plate with a pressure intensity of 0.163g/cm load at 10cm (measured along the hypotenuse after folding the stitch) from the vertex of the acute angle of the triangle, with the side of the square plate being parallel to the hypotenuse of the triangle;

③ measuring thickness before washing, taking 4 points of intersection of edge line of the square plate and folded edge line of the sewn product, measuring the height from the 4 points to the table top, and testing the other side according to the same method;

④ calculating the average of 8 points as the thickness before washing W1;

⑤ placing the sewn product in a mesh washing bag and then in a washing machine to wash according to JISL 0217103-1995;

⑥ measuring the thickness after drying, and measuring the height of 8 points according to the above method;

⑦ calculating the average value of 8 points as the thickness W2 after washing;

⑧ calculated thickness retention = W2/W1 x 100%.

As is clear from tables 1, 2 and 3,

(1) from examples 1 and 3, it is understood that the heat retaining property (the clo value) of the sewn product in which the long fiber cotton is fixed only to the surface layer is higher than that of the sewn product in which the long fiber cotton is fixed to both the surface layer and the back layer under the same conditions, but the washing durability is slightly lower than that of the sewn product in which the long fiber cotton is fixed to both the surface layer and the back layer.

(2) From example 4 and example 1, it is clear that the heat retaining property and the washing durability of the sewn product in which the long fiber cotton is fixed only to the textile are superior to those of the sewn product in which the long fiber cotton is fixed only to the surface layer under the same conditions.

(3) From example 5 and example 1, it is clear that the heat retaining property and the washing durability of the sewn product in which the long fiber cotton is fixed to the surface layer and the textile are superior to those of the sewn product in which the long fiber cotton is fixed to only the surface layer under the same conditions.

(4) From examples 7 and 5, it is understood that the heat retaining property and the washing durability of the sewn product in which the long fiber cotton is fixed to the surface layer and the back layer and the textile are superior to those of the sewn product in which the long fiber cotton is fixed to the surface layer and the textile under the same conditions.

(6) From examples 7 and 12, it is understood that under the same conditions, the heat retaining property and the washing durability of the sewn product of the continuous type seam track are superior to those of the sewn product of the discontinuous type seam track.

(7) From example 7 and example 13, it is clear that, under the same conditions, the heat retaining property and the washing durability of the sewn product in which the elongation of the long fiber cotton is larger than that of the lining fabric are superior to those of the sewn product in which the elongation of the long fiber cotton is smaller than that of the lining fabric.

(8) From example 14 and example 16, it is understood that under the same conditions, the heat retaining property and the washing durability of the sewing product with the elongation of the long fiber cotton of 190% are superior to those of the sewing product with the elongation of the long fiber cotton of 210%.

(9) From example 17 and example 7, it is understood that under the same conditions, the heat retaining property and the washing durability of the sewn product in which the elongation of the inner layer fabric is 5% are superior to those of the sewn product in which the elongation of the inner layer fabric is 0.

(10) From example 7 and example 22, it is understood that, under the same conditions, the heat retaining property and the washing durability of the sewn product in which the elongation of the long fiber cotton is larger than that of the surface layer fabric are superior to those of the sewn product in which the elongation of the long fiber cotton is smaller than that of the surface layer fabric.
