Abstract

The invention discloses waterproof down liner. The waterproof down liner comprises 80-85% of white goose down and 15-20% of white duck down. The down liner is coated with waterproof coating agent. The waterproof coating agent being 15-45% in mass concentration comprises, by weight, 60-80 parts of dodecanamide, 3-8 parts of silane coupling agent, 5-8 parts of ethyl hydrosilicone oil, 0.5-1.2 part of sodium polyacrylate dispersant, and the balance of water. The down liner is subjected to waterproofing coating and has superior waterproofing. A down coat made with the waterproof down liner is both highly waterproof and breathable. The down coat is still resistant to damp-induced deformation even in rainy days, and using effect and wearing comfort are totally unaffected.

Description

The waterproof down feather inner liner

Technical field

The present invention relates to a kind of waterproof down feather inner liner.

Background technology

Eider down is preferably up to now to be used for human warming natural material, after the PROCESS FOR TREATMENT such as washing, drying, classification, makes down jackets.Compare with artificial material, the warming ability of eider down is three times of general artificial material.The down products of producing the earliest has the shortcoming of revealing suede.Because the appearance of coated fabric makes down jackets reveal this shortcoming of suede and overcome, from then on down jackets become the main winter dress necessary article of people to this problem at 20 century 70s.Down jackets are the main products of Feather and down industry.Eider down is made of suede (Down) and plumage (Feather).High-grade down jackets are generally selected white goose down or the 90% above white duck down more than 90%, and the real down jackets warmth retention property more than 90% is strong, and fluffy degree is high again, and the down jackets dress is light again, comfortable again.Normal operation down content 90% eider down, the down jackets that fill suede amount 230g～320g (according to the commodity size) just adapt to the environment about northern minus 20 degrees～subzero 30 degree.

90% white goose down down jackets are by the feather that does not contain mao bar, and many bunches of filaments that grow at its pinnule have formed stable thermal-protective coating by the filament on the suede is interlaced.Therefore, suede is the main material of down thermal.Nearly 200 ten thousand filaments of the eider down of each ounce.The suede filament of better quality is longer, and the suede of formation is piece also corresponding larger.Plumage is the back of duck or goose and the featherlet with the plumage bar of afterbody, also has to fledge to smash rear formation, and the content of plumage can not be too high, but because it is improved the effect of eider down fluffy degree, therefore must contain certain ratio.After the PROCESS FOR TREATMENT such as the washing of eider down process, drying, classification, be made into down jackets.Become the dress ornament that keeps out the cold winter.Down jackets have anti-cold good, the advantage such as softly fluffy, convenient for washing, inexpensive and green pure be natural, so the consumer is more and more vigorous to the demand of down jackets, make the development space in down jackets market still very large.

Present down jackets generally do not possess water-proof function, and the make moist after-contraction distortion of the weather that rainy day or humidity are larger, the eider down in the down jackets inner bag can reduce its warming effect, deals with improperly and also can cause eider down caking, hardening, reduces degree comfortable and easy to wear.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of waterproof down feather inner liner, the defects that exists to overcome prior art.

For solving the problems of the technologies described above, waterproof down feather inner liner of the present invention comprises 80-85% white goose down and 15-20% white duck down, and described waterproof down feather inner liner is through the HAIR COLOR COMPOSITION spray treatment, and described HAIR COLOR COMPOSITION is comprised of the component of following weight portion:

Laurylamide 60-80 part;

Silane coupler 3-8 part;

Ethyl containing hydrogen silicone oil 5-8 part;

Sodium Polyacrylate dispersant 0.5-1.2 part;

Surplus is water, is made into the HAIR COLOR COMPOSITION that mass concentration is 15-45%.

Described Sodium Polyacrylate dispersant preferred viscosities 300-350mPas.

HAIR COLOR COMPOSITION adopts general mixed method to get final product.

The present invention carries out water-proof spraying to down feather inner liner and processes, and has excellent waterproof effect, and make waterproof behind the down jackets, air permeable effect is all good.Even under the rainy day situation, can not make moist distortion yet, not affect result of use and degree comfortable and easy to wear fully.

The specific embodiment

Embodiment 1

The waterproof coating agent prescription:

60 parts of laurylamides;

8 parts of silane couplers;

7 parts of ethyl containing hydrogen silicone oils;

1 part of Sodium Polyacrylate dispersant;

Adding water after each component is mixed, to be made into mass concentration be 40% HAIR COLOR COMPOSITION.

Above-mentioned HAIR COLOR COMPOSITION is evenly sprayed on the down feather inner liner, and down feather inner liner is comprised of 80% white goose down and 20% white duck down, obtains the waterproof down feather inner liner.

Embodiment 2

The waterproof coating agent prescription:

80 parts of laurylamides;

8 parts of silane couplers;

5 parts of ethyl containing hydrogen silicone oils;

0.6 part of Sodium Polyacrylate dispersant;

Adding water after each component is mixed, to be made into mass concentration be 20% HAIR COLOR COMPOSITION.

Above-mentioned HAIR COLOR COMPOSITION is evenly sprayed on the down feather inner liner, and down feather inner liner is comprised of 85% white goose down and 15% white duck down, obtains the waterproof down feather inner liner.
