How Do I Choose the Best Eyelash Perm Kits?

Posted on by

The best eyelash perm kit is intended for at-home use, contain multiple applications, and have step-by-step simple instructions. These kits can help you to achieve a long-lasting eyelash curl, similar to the temporary results achieved by using a metal eyelash curler. Perming eyelashes can eliminate the need to curl eyelashes daily or to wear mascara. Eyelash perming kits are best handled and applied by a professional, but they are available for at-home use as well.

 

It may be difficult to find eyelash perming kits sold for at-home use due to the potential dangers associated with getting chemicals in the eyes. Choosing a kit that is intended specifically for at-home use will help ensure a smooth, injury-free eyelash perming experience. Kits intended only for use by salon professionals may not contain the detailed instructions needed by someone new to the eyelash perming process. If you attempt to use a kit at home, wear gloves at all times, and be sure to cleanse the eyes and eyelashes well after perming.

 

Browse reviews of eyelash perm kits to find a brand that has been satisfactory to other consumers, or ask for a recommendation in-person from an associate at a beauty supply store. The best kits contain pads for protecting the eyes and cleaning solution to remove the perming chemicals after the curling process is complete. Protecting the eyes from the perming chemicals used is of utmost importance. It may be useful to practice the eyelash rolling and setting techniques on a mannequin or on false eyelashes before attempting it on yourself. Watching online tutorial videos can also help clarify the process.

 

There are several dangers associated with eyelash perm kits. The U.S. Food and Drug Administration have not approved any perming kit. Using a kit at home instead of having a professional perform the task increases the risk, as it can be difficult to properly apply the solution to one’s own eyelashes. Self-perming can also negatively affect results, as errors in the process can lead to uncurled or lopsided lashes or can cause the lashes to fall out. If the perming solution accidentally comes into contact with the eyes, the eyes should immediately be flushed with water to prevent potentially serious damage.

 

An eyelash perm typically lasts two or three months, around the time it takes for eyelashes to grow out. Most kits come with multiple applications, and choosing one of these kits is often the most economical choice. The perm process usually takes about an hour. Some choose to combine perming with other eyelash-enhancing procedures, such as the application of false eyelashes or dye.

Introduction of Unidirectional Fabric

Posted on by

A unidirectional (UD) fabric is one in which the majority of fibres run in one direction only. A small amount of fibre or other material may run in other directions with the main intention being to hold the primary fibres in position, although the other fibres may also offer some structural properties. Some weavers of 0/90° fabrics term a fabric with only 75% of its weight in one direction as a unidirectional, whilst for others the unidirectional designation only applies to those fabrics with more than 90% of the fibre weight in one direction. Unidirectionals usually have their primary fibres in the 0° direction (along the roll ­ a warp UD) but can also have them at 90° to the roll length (a weft UD).

 

True unidirectional fabrics offer the ability to place fibre in the component exactly where it is required, and in the optimum quantity (no more or less than required). As well as this, UD fibres are straight and uncrimped. This results in the highest possible fibre properties from a fabric in composite component construction. For mechanical properties, unidirectional fabrics can only be improved on by prepreg unidirectional tape, where there is no secondary material at all holding the unidirectional fibres in place. In these prepreg products only the resin system holds the fibres in place.

 

Unidirectional Construction

 

There are various methods of maintaining the primary fibres in position in a unidirectional including weaving, stitching, and bonding. As with other fabrics, the surface quality of a unidirectional fabric is determined by two main factors: the combination of tex and thread count of the primary fibre and the amount and type of the secondary fibre. The drape, surface smoothness and stability of a fabric are controlled primarily by the construction style, while the area weight, porosity and (to a lesser degree) wet out are determined by selecting the appropriate combination of fibre tex and numbers of fibres per cm.

 

Warp or weft unidirectionals can be made by the stitching process. However, in order to gain adequate stability, it is usually necessary to add a mat or tissue to the face of the fabric. Therefore, together with the stitching thread required to assemble the fibres, there is a relatively large amount of secondary, parasitic material in this type of UD fabric, which tends to reduce the laminate properties. Furthermore the high cost of set up of the 0° layer of a stitching line and the relatively slow speed of production means that these fabrics can be relatively expensive.
