Description

Down pants

Technical Field

The invention belongs to the field of clothes, relates to down pants, and particularly relates to high-elasticity down pants capable of preventing down penetration.

Background

The prior art has two problems. Firstly, the down pants are not elastic, uncomfortable to wear and limited in movement; secondly, the down trousers are densely provided with needle holes, down can be drilled out along the needle holes, and the problem of down drilling cannot be solved.

The elastic problem is mainly solved by two methods in the prior art, firstly, the trouser legs are designed to be particularly fat, and the size required by activity is reserved, but the design is that the trousers are too fat, the trousers cannot be covered, and the appearance is not attractive; secondly, the screw openings with the length of 4-5 cm are added at the seams of the trousers to increase the transverse elasticity of the trousers, but in this way, the screw openings are thick and heavy, the processing difficulty is high, the trousers are easy to open, the trousers are thick and heavy, the comfort is poor, and compared with the heat preservation of down feather, the screw openings have poor heat preservation, and cold air can flow inwards along the screw openings to influence the heat preservation of the down feather trousers.

In order to uniformly distribute down on clothes, the clothes are divided into a plurality of small areas by sewing threads with a machine needle, and then down filling treatment is carried out to ensure uniform distribution of the down, which causes a problem. This is a difficult problem that has plagued clothing men for many years. Secondly, because the density of the common fabric is low, down can not be prevented, two layers of high-density liner cloth are required to be added between the fabric and the lining, and the down rushes into the liner cloth, so that four layers of cloth are formed from inside to outside, and the more the number of the cloth layers is, the more the flexibility and the comfortableness of the trousers are limited and the heavier the trousers are.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides down pants which have high elasticity, are down-proof, comfortable and warm.

The technical scheme adopted by the invention is as follows:

a pair of down pants comprises a front piece and a rear piece, wherein the front piece and the rear piece are both shells, down is filled in the shells, the shells of the front piece and the rear piece are both formed by one-time spinning, the front piece and the rear piece are both made of weft elastic fabric, and the weft elastic fabric is formed by weaving 80-90% of superfine nylon and 10-20% of spandex; the elasticity coefficient of the weft elastic fabric is larger than 12.5%.

Furthermore, the weft elastic fabric is formed by weaving 87% of superfine nylon and 13% of spandex.

Further, the superfine nylon is 20D nylon, and the elasticity coefficient of the weft elastic fabric is 12.8-13.0%.

Furthermore, the shell of the front sheet or the rear sheet is internally divided into a plurality of transverse chambers, each chamber is provided with a filling port, and each row of chambers are sequentially communicated through the filling ports; the filling port between two adjacent chambers is connected with a lint-blocking cloth, and the lint-blocking cloth is enclosed into a filling channel for filling heat-insulating materials.

Further, the filling openings are oriented in a consistent manner.

Further, the central lines of the filling openings of two adjacent chambers are on the same straight line.

Furthermore, the axis of each filling channel coincides with the midline of the corresponding filling port, and each flock blocking channel penetrates through the corresponding filling port.

Furthermore, two pieces of lint-blocking cloth which are identical in shape and size are connected to each filling opening, and the two pieces of lint-blocking cloth are oppositely arranged on two sides of each filling opening.

Furthermore, the filling ports are connected with the middle part of the lint resisting cloth.

The left and right sides of the two pieces of lint resisting cloth are connected, and the upper and lower sides are not sealed to form a cylinder shape, so that a lint filling channel is formed.

Further, the down-blocking cloth is polyester cloth.

The warp yarns of the weft elastic fabric are combined by adopting 75DPOY yarns and 68DFDY filaments in a grid-connected mode; the weft yarn 100D low stretch yarn and the coated 40D spandex yarn are woven by an advanced air jet loom in a fabric system of 1/4 satin change method weave structure, and after twice air jets, the fabric is soft and smooth in hand feeling, good in velvet feeling and high in transverse elasticity.

The front piece and the rear piece are both made of weft elastic fabric, preferably, the warp yarn of the weft elastic fabric is formed by combining and compounding 20DPOY yarn and 20DFDY filament yarn which are made of superfine nylon; the weft yarns are woven by adopting a 20D low-elasticity nylon yarn and a 40D spandex yarn-coated ultrahigh-density textile process. Wherein, the yarn count density is 521-. The ultrahigh-density textile enables the fabric to have better heat retention and is not easy to burrow.

Nylon is a way of Polyamide fiber (nylon), can be made into long fiber or short fiber, the English name is Polyamide (PA for short), Polyamide is mainly used for synthetic fiber, the most outstanding advantage is that the wear resistance is higher than all other fibers, 10 times higher than the wear resistance of cotton, 20 times higher than wool, and the wear resistance can be greatly improved by slightly adding some Polyamide fibers into blended fabric; when the stretch is extended to 3-6%, the elastic recovery rate can reach 100%; can withstand ten thousand times of bending without breaking.

FDY, FULLY DRAWN YARN, FULLY drawn yarn (taiwan called FULLY drawn yarn), which is a FULLY drawn yarn, can be obtained as a wound yarn having a high degree of orientation and a medium degree of crystallinity by introducing a drawing action during spinning. The conventional fully drawn yarns with terylene and chinlon belong to chemical fiber filaments. The FDY fabric has smooth and soft hand feeling and is often used for weaving the silk-like fabric. Has wide application in clothing and home textiles.

POY is spun at high speed to produce partially oriented, wound filaments, POY for short. The chemical fiber filament with the orientation degree between non-oriented yarn (UDY) and drawn yarn is obtained by high-speed spinning. It has the characteristics of higher orientation degree (general birefringence is 0.025-0.060), larger elongation at break (150-.

When the down pants are knitted, the front piece and the rear piece are both shells formed by one-time spinning, and the shells are internally provided with a plurality of cavities without later sewing. In the prior art, a plurality of cavities need to be sewn by threads, and the dense and hemp needle holes are easy to drill down. The shells of the front piece and the back piece are respectively filled with down after being knitted and formed, and then the edges of the front piece and the back piece are sewn into the down pants.

The invention has the beneficial effects that:

the down pants adopt the weft elastic superfine nylon fabric, the elasticity coefficient of the adopted superfine nylon fabric is close to 13 percent, the problem of insufficient elasticity of the down pants is effectively solved, and the down pants are more flexible and comfortable when squatting, stepping and other actions are performed after being worn;

the down pants adopt a one-time textile forming technology, do not need to be separately sewn in the later period, have double layers with partitions, avoid the generation of needle holes and effectively prevent down from drilling out.
