Description

1 TARIFF Pile Loop Tensile Test Device TECHNICAL AREA 5 The invention generally aims to improve the quality and performance of nap fabrics. It relates to the testing equipment that enables the investigation. The invention relates to the formation of fibers on the surface of nap fabrics, distributed by the nap fibers. determining the tensile strength of the loops formed on the fabric and the determined It relates to a loop tensile testing device that allows analysis based on force. STATE OF THE ART Pile fabrics, produced by weaving or knitting, have ground and pile surfaces. It consists of two different surfaces, forming the air surface. Pile fabrics are obtained by bonding the yarns between the ground yarns. It is made. Pile loops are the part of the pile yarns that are visible on the fabric surface. It is found in a free and loose form and is particularly sensitive to any contact, especially 20 The fabric is looped when it comes into contact with protruding surfaces or objects. It is pulled outwards from the surface. The loops pulled outwards are elongated yarn. Its appearance is quite disturbing and off-putting to the consumer, even giving the impression of a defective product. It causes too many loops to be pulled from the surface or the loop threads to break. In these cases, the integrity of the pile fabric is compromised, and consequently, the product's usability is reduced. Its lifespan is shortening. Prior to 2021, the existing technique aimed to solve the aforementioned loop pulling problem. No studies have been conducted with the aim of addressing this issue, nor has any research been done on the fabric causing this problem.
