Winter clothing

Cotton wadded jacket, a coat of thermal insulation materials such as cotton wool. Eclectic style.

A good cold-proof suit is actually stitching two parts of the cold-proof suit together-the inner part is cold-proof, and the outer part serves as a windshield. The inner layer mainly uses a layer of nylon lining, and then adds the key ingredients: a film that stabilizes and protects the thermal insulation material, and a thick layer of polyester thermal insulation material. At this time, the warmth layer is larger than the lining-this guarantees that every part of the jacket is warm.

There are three types of cold protective clothing: ordinary cold protective clothing, plateau cold protective clothing, and extremely cold cold protective clothing.

Ordinary cold protection clothing is designed in ordinary cold regions, and daily cold insulation such as cotton jackets and down jackets is ordinary cold protection clothing.

Plateau cold suits are based on ordinary cold suits and are designed for plateau cold regions. The plateau environment is windy and the air is thin. The design of cold suits must consider how to solve the load on the premise of effective warmth.

The extreme cold suit is based on ordinary cold suits and is designed for high cold areas. It must be able to tolerate the severe cold of -50 , emphasize wind protection, cold protection, and breathability. It must keep warm while letting skin moisture out. In order to achieve the level of cold protection under extreme cold conditions, it is possible to consider increasing the thickness of the cold-proof floc.

The following are the ambient temperature conditions when thermal equilibrium is reached under different activities and different contact times (minimum temperature is for reference only):

Very small activities (1) Small activities (2) Moderate activities (3)

Wearing time: 8 hours + 6 ° C -4 ° C -26 ° C

Wearing time: 1 hour -9 ° C -30 ° C -30 ° C

-Very small activity, body metabolism 90 W / m2 (stand still or sit, slightly arm movement)

-Small range of activity, body metabolism 115 W / m2 (walk or stand at 2 km / h with slight arm movement)

-Moderate activity, body metabolism 170 W / m2 (walk or stand at 4 to 5 km / h, upper body activity)

These values are set under no wind conditions, when the radiant temperature is equal to the ambient air temperature. In these cases, adequate protection must be provided for the hands, feet and head.

These values are measured without the sleeves removed and the entire garment closed.

The recommended maximum wear time for the entire outfit (top and pants, without thermal lining) is as follows:

Working environment temperature level 1 * Ret> 40 level 2 20 <Ret40 level 3 Ret20

25 ° C 60 minutes 105 minutes 205 minutes

20 ° C 75 minutes 250 minutes-

15 ° C 100 minutes--

10 ° C 240 minutes--

5 ° C---

"-" Means no wearing time limit.

(*) Clothing with Ret (water vapor protection performance) level 1 should be worn in accordance with the working temperature of the table above.

The applicable conditions of this form are: medium physiological acceptance intensity (M = 150W / m2), standard operator, relative humidity of 50%, effective ventilation opening speed Va = 0.5m / s.

Intermittent use can extend clothing wear time.

The maximum cleaning temperature is 30 ° C. Avoid mechanical treatment and dehydration as much as possible. Rinse normally. Do not use chlorine bleach. Do not iron or steam. Do not dry clean or decontaminate with detergent. Do not spin the drum. Storage Please keep cold protective clothing in the original packaging, and keep it in a dry place away from sunlight.

Stain soak

Before soaking in the winter clothing, first remove the dust on the surface and inside of the clothing with a clothes brush, then use a soft brush to soak the water in the detergent to remove the dirt on the collar, cuffs and excessively dirty parts, and then soak the winter clothing in water (Can not be twisted) and wait for washing.

cleaning method

When choosing the detergent for cold protection clothes, it is best to choose a detergent with little foam, little alkaline or neutral. Such detergent is conducive to clean water and protect fibers. During operation, first take an appropriate amount to dissolve in a small amount of warm water according to the instructions of the detergent, and then inject 20 ° to 40 ° of clear water. The soaking time is 3 to 5 minutes, that is, squeeze by hand, but do not knead, and tumbling while squeezing, repeat for 3 to 5 minutes. After washing, lift the collar of the cold-proof clothing, and squeeze the sewage out by hand from top to bottom. Do not twist it to prevent wrinkling the surface and twist the core-lined cotton.

Remove dirt

Put the squeezed winter clothing into more water. In order to maintain the brightness of the winter clothing, you can add a little white wine or edible vinegar when it is cleared for the first time, and repeatedly flip, swing, and squeeze to dissolve the dirt of the winter clothing. In the water, squeeze out the sewage. Repeat the cleaning process three to four times until the squeezed water is pure.

Dehydrated shade

In order to prevent the winter clothing from deforming and leaving no water stains, it is necessary to use absorbent cotton products (such as large towels, small cotton blankets, etc.) to help absorb moisture. Flatten the washed cold-proof clothes on the desk, and place a large towel on both the front and back, and put a large towel in the sleeve. The cold-proof clothing and a large towel are rolled into a tube and squeezed, so that the moisture of the cold-proof clothing penetrates into the absorbent material. Repeat several times until the water is squeezed out. Then spread the collar, sleeves, front placket and other parts of the cold-proof clothing, put it on a hanger, and hang it in the shade and ventilation place to dry.

Basic requirements for winter clothing

(1) Windproof and breathable: Most of the winter clothing has a certain degree of windproofness. Ventilation is an important aspect of comfort in winter clothing.

(2) Anti-fleece: There are three ways to enhance the fleece resistance of down fabrics. One is to lay a film or coating on the base fabric, and prevent the lint from leaking through the film or coating. Of course, the first premise is breathable and not Affects the lightness and softness of the fabric. The second is to pass the post-processing of high-density fabrics to improve the fabric's fleece resistance. The third is to add a layer of velvet cloth in the down fabric, the quality of the velvet cloth will directly affect the quality of the garment.

(3) Lightweight and soft: In today's lightweight equipment, the lightness of down jacket fabrics will directly affect the overall weight of a down jacket, and soft fabrics, for bloated down jackets themselves, will enhance the elderly's wearing down jackets Comfort. On the other hand, light and soft fabrics help to better play the fluffyness of down, so the warmth will be higher ^[1] .

Specific tips for winter clothing

I. The various marks on the winter clothing should be complete, such as the name of the factory, the location of the fabric, the content of the fabric lining, the weight of the cotton, the type of down and the index of the amount of down, the amount of filling, the logo of washing, and the quality Labels, quality levels, implementation standards, etc.

Second, it is necessary to pay attention to whether there is a plastic film and fake air-impermeable linings in the winter clothing.

Third, it should be purchased at large and medium-sized shopping malls with quality reputation and standardized after-sales service, in order to protect their legitimate rights and interests.

Fourth, look at the style: novel, chic, fit, generous and practical, as well as detachable.

Fifth, look at the price: It is generally appropriate to have a moderate price. If the price is too low, the inherent quality of the winter clothing cannot be guaranteed, and various quality disputes are prone to occur.

Sixth, try to wear cold-proof clothing, especially the size of the bust should be moderate, wear a sweater inside, and then put on a cotton jacket, down jacket, you must feel neither tight nor loose to fit.

Seven, cotton weight, velvet content and filling amount: should choose the velvet content and filling amount suitable for their needs. The fleece content of the winter clothing is generally 70% or more, which has a certain degree of fluffyness and softness. The amount of filling is related to the degree of warmth of the winter clothing, which should be determined according to the needs of the person wearing it. The same is true for cotton clothes. The weight of cotton is determined according to the needs of wearing.

8. Resilience: Puff the fluffy cold-proof clothing, and then release it, and then quickly rebound to restore the original shape, indicating that the fluff of cotton and down is good. If the amount of fleece is low and a certain amount of flakes or crushed hair is mixed, the resilience is poor, and the cold-proof clothing is heavy in the hand. Cotton clothing is based on your preferences to choose cotton or fluffy cotton.

Nine, anti-drilling cotton, fleece performance: cotton, down products should have anti-drilling cotton, down performance. Take a pat, shake it, and find that drilled cotton, down cotton, and down products are definitely inferior. Due to the silky nature of down, it is normal for a small amount of down to overflow from the suture. Cotton is rarely spilt.

X. Breathability: Cold-proof clothing cannot drill cotton and velvet, but it must also have a certain degree of breathability. For example, the fabric, lining, and gall material of the cold-proof clothing have poor air permeability. Feeling uncomfortable and not warm. The second is that it is not easy to dry after washing. The above two factors will cause the cotton clothes and down to deteriorate to different degrees under humid conditions, and emit odor.

XI. Smell: Smell it, and take a deep breath next to the down products. Smell the scent inside to avoid buying pungent products, but because it is animal feathers, it is normal to have a certain smell.

12. Auxiliary materials: On a piece of cold protection clothing, there are a lot of auxiliary materials, such as zippers, metal buckles, etc. Are they beautiful, smooth and elastic. Children's clothing must not have sharp and easily removable decorations.
