Description

Filler and use thereof Technical field

The invention relates to a filler body and its use.

Background technique

As we all know, feathers have excellent bulkiness and heat preservation, occupying the first place in the raw materials for making quilts, jackets, etc., but at the same time, they also have problems such as difficulty in washing, smell, and easy to slip, especially after a long time. It will make a stench.

In order to improve these defects of feathers, many other types of fillings have also been considered. For example, pearl cotton, which is a ball-shaped cotton made of three-dimensional crimped hollow fiber, automatically expands after quilting, and is not easily deformed even after machine washing, but the gas permeability is not so good, and if the filling amount is improper, it is easy to concentrate after washing. Leaky, difficult to distribute evenly.

In order to solve the problem of the washing durability of the filling, a filling body is disclosed in the patent document CN103097280A, which is formed by integrating a core yarn with a fancy yarn which is opened to form a loop fiber, and the long fiber filling cotton is at least one. The yarn is woven in a plurality of directions in the direction and is sewn together with the cover cloth to be integrated with the cover cloth. Even if the long-fiber cotton used as the filler is washed for a plurality of times, the movement is restricted, and the concentration is small and the bulkiness is high. The advantages, but no solution to the gas permeability of the filler body, etc.

In addition, in the field of down jackets, in order to achieve the purpose of putting down the body and body, a stretchable elastic down jacket is disclosed in the patent document CN2595204A. Both the fabric layer and the lining layer are stretched elastic fabric, and the inner layer of the lining layer and the fabric layer are composited. There is a flexible film, but due to the presence of the elastic film, the breathability of the down jacket will be affected; and the film may fall off after washing, which affects the quality of the down jacket; at the same time, the problem of easy pile accumulation after washing still exists.

Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a filler body having excellent washing durability and excellent gas permeability which is obtained by using long fiber-filled cotton instead of feather as a filler, and use thereof.

The filling body of the invention comprises a filling material between the surface layer fabric, the inner layer fabric and the surface layer fabric, wherein the ventilation of the inner layer fabric is between 10.0 and 200.0 cm ³ /cm ² /s, and the filling is a core sheath.

The invention solves the problem of wearing stuffy feeling by selecting the inner layer fabric with specific ventilation amount; at the same time, by using long fiber filling cotton, the inner layer fabric and the surface layer fabric are not easy to leak even if high density is not used, and the feather washing is avoided. After the easy concentration, there is a phenomenon of odor.

detailed description

The filling body of the invention comprises a filling material between a surface layer fabric, an inner layer fabric and a surface layer fabric; wherein the inner layer fabric has a ventilation capacity of between 10.0 and 200.0 cm ³ /cm ² /s, and the filling is a core sheath The long fiber of the structure is filled with cotton, and at least contains long polyester fibers. The surface layer and the inner layer fabric used in the present invention may be a woven fabric or a knitted fabric. The fiber raw material to be used is not particularly limited, and polyester fiber or nylon fiber is preferable in view of cost and the like.

In the present invention, the ventilation amount of the inner layer fabric is required to be between 10.0 and 200.0 cm ³ /cm ² /s, and if the ventilation amount is less than 10.0 cm ³ /cm ² /s, there is a stuffy feeling; and more than 200.0 cm ³ /cm. ² / s, even with long fiber filled cotton is easy to drill. In the present invention, it is preferred that the aeration amount of the surface layer fabric is also between 10.0 and 200.0 cm ³ /cm ² /s. In the selection of the fabric, for example, in order to obtain a light and warm warming effect, a lightweight high-density woven fabric can be used; in order to obtain a stretchable movement effect, an elastic knitted fabric or woven fabric can be used.

The long-fiber-filled cotton used in the present invention is composed of long fibers having a core-sheath structure. The single fiber of the sheath filament forms a three-dimensional multi-annular shape while forming an intersection point through the core fiber bundle, and the intersection is not a fixed fusion point and can move freely within a certain range. When deformed by external force, the intersection of the long-fiber cotton will undergo a certain displacement to absorb the external force, and after the external force is removed, the original state will be restored. In the fiber-forming polymer, the Young's modulus of the polyester fiber is relatively high, so the long-fiber-filled cotton produced therefrom has good pressure resistance and recovery, thus forming the invention. The fiber raw material for the core yarn and the sheath yarn of the fiber-filled cotton is required to contain at least polyester long fibers. The filament thickness of the sheath filament and the core filament is preferably in the range of 3.5 dtex to 10.0 dtex.

Preferably, the core filament forming the filling of the present invention further contains an elastic fiber. The presence of the elastic fibers allows the long-fiber-filled cotton to elongate as the filler body elongates, improving wearing comfort. If the elastic fiber is contained in the sheath wire, the wire length difference between the sheath wire and the core wire becomes small, and the bulkiness tends to decrease. The elastic fiber here may be a spandex bare silk or a spandex covered yarn (core spun yarn); or a polyester elastic fiber such as a high elastic yarn or a low elastic false twisted textured yarn, polybutylene terephthalate. / Side-by-side composite fiber such as polyethylene terephthalate (PBT/PET), polybutylene terephthalate (PBT), and the like. The content thereof is preferably from 0.5% by weight to 10.0% by weight, more preferably from 1.0% by weight to 6.5% by weight, based on the long-fiber-filled cotton. If the content of the elastic fiber is less than 0.5% by weight, the stretchability of the long-fiber-filled cotton is difficult to be manifested, which may restrict the movement of the human body; and if the content of the elastic fiber is more than 10.0% by weight, not only the cost may increase, but also may occur. Broken yarn and other phenomena.

Preferably, the filler of the present invention further comprises a ribbon, one side of which is joined to the front filler and the other side to the inner skin. The ribbon herein may be a woven tape, a belt-like nonwoven fabric, a belt woven fabric or a belt knitted fabric or the like. By using the ribbon to connect, it is possible to avoid the phenomenon of leakage at the pinhole during the quilting process. The width of the ribbon is preferably greater than 0.6 cm, more preferably from 0.6 to 10.0 cm. If the ribbon is too wide, it may affect the heat retention and weight reduction of the filler.

Preferably, the filling of the present invention has an elongation in the longitudinal direction of 1.0% to 200.0%, and within this range, the filling has a certain degree of motion followability, that is, the filling does not hinder the body during exercise. Stretching exercises improve athleticism. The elongation is more preferably from 1.0% to 80.0%. The elongation here may be either the long-fiber filled cotton itself as a filling or the external force by attaching a belt to the end of the filling.

Preferably, at least one of the fabric and the lining of the filler of the present invention is an elastic fabric. Here, the elastic fabric has an elongation in both the transverse direction and the longitudinal direction of 5.0% or more, and may be an elastic woven fabric or an elastic knitted fabric. The elasticity of the fabric can be obtained by using elastic fibers, a specific tissue structure, or a combination thereof. Elastic fibers such as spandex covered yarn (core yarn), polyester elastic fiber, and the like. The polyester-based elastic fiber is either a one-component elastic fiber, a two-component side-by-side elastic fiber (such as PBT/PET, etc.), or a high-elastic false-twisted yarn (such as polyester high-elastic DTY). The high elastic DTY in the present invention means a yarn having an elastic stretch ratio of 5% to 20%, and the ordinary DTY is a yarn having an elastic stretch ratio of less than 5%. Specific tissue structure such as twill weave of woven fabric, satin weave, etc., rib structure of knitted fabric, double reverse tissue, warp flat structure, satin weave, and the like. In autumn and winter, when wearing a winter jacket for life, study or work, the elbow joint and the knee joint are more curved. When the elastic elongation of at least one of the warp and weft directions of the elastic fabric is less than 5%, relatively speaking, these The activity of the part tends to be deteriorated. Therefore, the elastic fabric used in the present invention preferably has an elastic elongation in the warp and weft directions of not less than 5%, and the wearing comfort can be further improved.

Preferably, the filler of the present invention is obtained by ultrasonic sewing. Ultrasonic sewing can fuse the end of the filling with the fabric of the inner layer. Compared with the stitching, it can reduce the probability of leakage, and it is not easy to appear short hairiness, which can effectively improve the elongation of the filling in the longitudinal direction. Rate to ensure washing durability.

Preferably, the bottom thread used for sewing the filler of the present invention may be a elastic thread of a core structure; or may be a normal elastic thread such as a polyester elastic thread and a nylon elastic yarn.

Preferably, the filler of the present invention further comprises polypropylene long fibers. By utilizing the lightweight insulation properties of polypropylene long fibers, the filler body has superior thermal insulation properties based on further weight reduction. The content thereof is preferably 0.05% by weight to 50% by weight, and more preferably 0.1% by weight to 30% by weight based on the total weight of the long-fiber-filled cotton. Since the Young's modulus of the polypropylene long fiber is relatively light, if the content is more than 50% by weight, the rigidity of the long fiber filled cotton is lowered, and the bulkiness tends to decrease.

Preferably, after the filler of the present invention is washed for 5 times, the elongation change rate of the filler in the longitudinal direction is 10.0% or less, and the offset ratio in the width direction is 20.0% to 60.0%. If the elongation change rate of the filler in the longitudinal direction exceeds 10.0% after washing, the two ends may have detached from the seam; it is also possible that excessive entanglement distortion has occurred in the filling, and the warmth retention tends to decrease. .

Preferably, the filler of the present invention is a long-fiber-filled cotton in which air-wound is integrated. Through the integration of air winding, the sheath wire is formed into a coil, which can increase the bulkiness of the long fiber cotton and improve the warmth.

The filling body of the invention can be widely used for making jackets, pants, vests, jumpsuits, jackets, quilts, pillows, sleeping bags, underwear, pajamas, sweaters, tight pants, socks or sportswear.

The pileability, the appearance effect, the elongation change rate of the filled cotton in the longitudinal direction, and the offset ratio in the width direction are all comparable; however, the former is less comfortable to wear than the former.

(10) It can be seen from Comparative Example 1 and Example 1 that under the same conditions, the filling body obtained by using the aeration amount of 8.4 cm ³ /cm ² /s as the inner layer fabric and the ventilation amount of 13.5 cm ³ /cm ² /s were used. Compared with the filler obtained from the inner layer fabric, the former has poor air permeability.

(11) It can be seen from Comparative Example 2 and Example 15 that under the same conditions, the filling body obtained by using the aeration amount of 244.0 cm ³ /cm ² /s as the inner layer fabric and the ventilation amount of 189.0 cm ³ /cm ² /s were used. Compared with the filler body obtained from the inner layer fabric, the former has poor heat preservation properties.

(12) It can be seen from Comparative Example 3 and Example 1 that, under the same conditions, the filler body obtained by using the spandex bare yarn/nylon fiber as the filling cotton and the filler body using the spandex hollow/polyester fiber as the filling cotton are compared with the former. Both the heat retention and the appearance after washing are relatively poor.
