Description

TECHNICAL FIELD The present invention relates to the field of non-slip products, in particular to an anti-slip film and its preparation method and application.

As people's living standards have improved, the pursuit and commitment to dressing and coordinating has increased, and not only dressing but also comfort has come to be demanded. People prefer to wear clothes that can be kept in place and retain their original shape for a long period of time in order to keep the clothes more beautiful and comfortable. However, a great many garments today suffer from reduced slip resistance, and when people are wearing them, body movements and relative slippage with coordinating garments can cause the garment to fall into the initial position of wear. It cannot be held in place, reducing the wearer's comfort and aesthetics.

To prevent clothing from slipping, people often attach anti-slip structures to some clothing, and anti-slip structures are commonly used to keep the fabric in place against the wearer's thighs or arms. They are typically placed on the inside of the wearer's body near the folds of the thighs (e.g. shorts) or sleeves (sportswear outerwear) to reduce slippage on clothing on or under the skin and to prevent the free ends from folding over. prevent. Particularly in the hosiery or underwear industry, anti-slip structures are often provided on the inside of the heel and ankle of socks, or on the underbust and shoulder straps of underwear. At present, the material of the non-slip structure is usually silicone elastic polymer material or silica gel material, which is made by printing a silicone layer or liquid silica gel on the inside of the garment by screen printing process, and drying it at high temperature to solidify. However, the thickness of the non-slip structure manufactured by the above manufacturing method using silicone elastic material or silica gel material is thick, and the elasticity and shrinkage properties decrease after long-term use, which reduces the anti-slip effect of clothing. However, it affects the aesthetic appearance of the clothing, and some people are allergic to it, so it greatly reduces the comfort of wearing.

Therefore, when the non-slip film of any of Examples 1 to 3 is applied to clothing such as socks, underwear, gloves, pants, sunscreen clothing, or protective clothing, the friction at the contact position of the clothing and the wearer's body is increased. This effectively prevents the clothing from slipping on the wearer's body, and the wearing comfort is excellent with almost no cramped feeling.

(Example 4)
In order to better explain the installation position of the anti-skid film in the present invention, the present invention provides a schematic structural diagram of a shallow sock with an anti-skid film. As shown in FIG. 1, the sock includes a sock body 1 and a cuff 6. The sock body 1 includes a heel portion 4, a body portion 3, and a toe portion 2. A non-slip film 5 is provided. The anti-slip film provided in this sock is the anti-slip film obtained in any one of Examples 1 to 3, and in the present invention, the anti-slip film obtained in any one of Examples 1 to 3 is A sock having a locking structure is referred to as Example 4.

The material of the non-slip film in the comparative example is silica gel or silicon, and other parts are the same.

In order to test the wearing effect of the non-slip film prepared by silica gel or silicon material of Example 4 of the present invention (adopting any of the non-slip films of Examples 1 to 3) and the comparative example, the present invention 200 males and 200 females were randomly selected to try on the socks with anti-slip film of any of Examples 1 to 3 and the socks of the comparative example. 100 out of 200 men were selected as group A to try on the socks with anti-slip film according to any of Embodiments 1 to 3 of the present invention, and the remaining 100 men were group B, prepared with silica gel material. Try on socks with an anti-slip film, similarly select 100 out of 200 women as group C, try on the socks with an anti-slip film of any of Examples 1 to 3 of the present invention, and the remaining 100 Named group D, they were asked to try on socks with anti-slip membranes prepared with silica gel material. The four groups A, B, C, and D are basically the same in terms of external factors such as the type of shoes and walking time, and after wearing the socks for 3 days and washing them twice, , A, B, C, and D, the results of investigating the state of the sock coming off the heel when trying on the sock, the elastic effect, and the wearing comfort are shown in Tables 1 and 2, respectively. Here, the numbers in the table represent the number of people.

As can be seen from the results in Tables 1 and 2, regardless of gender, when wearing socks having an anti-slip structure made of the anti-slip film prepared according to the present invention, the probability of slipping off (off) from the heel is within 2%. It has very good elasticity and comfort. From this, it can be seen that the non-slip film prepared by the present invention not only has a very good anti-slip effect, but also has excellent elasticity and excellent wearing comfort.
