In the method, one or more kinds of compounds selected from glyoxal resins or silicone compounds are formulated in the finishing agent. The fabric is treated by either a padding/drying method using a tenter or a dipping method using a jet dyeing machine or a drum dyeing machine. Thereby, the fiber structure treated with either one of the methods for finishing has the antisticking functions for the pollen. <P>COPYRIGHT: (C)2004,JPO

[Industrial application fields]
The present invention relates to a fiber structure having a pollen adhesion preventing function and a processing method thereof, more specifically, dust such as pollen is difficult to adhere, and even when pollen or the like adheres, it is easy to fall by tapping lightly, The present invention relates to a fiber structure having good soil diffusibility (hereinafter sometimes simply referred to as SR property) and good stitch slip-off property and a processing method thereof.
[0002]
[Prior art]
Various pollen such as cedar and cypress pollen in early spring, pollen of gramineous plants such as camouflage in May, ragweed pollen from the end of August, mugwort and rice pollen in September, pollen of autumn asteraceae, etc. from spring When it floats in the air until autumn and pollen enters the body, it becomes hay fever, and various symptoms such as sneezing, runny nose, headache, lacrimation, blurred vision and general malaise appear. In Japan, about 4.5 million hectares are planted with cedar alone, and cypress is planted about 2.4 million hectares. Together, these amounts to about 70% of the total population of Japan, and each year a huge amount of forest (Estimated: about 1 million tons) pollen is produced, and it is estimated that about 13 million people suffer from hay fever.
[0003]
The cedar pollen has an elliptical hemisphere shape with a major axis of about 30μ and a concave central part, and has a granular material with a major axis of about 1μ on the surface. It is easy to adhere to clothes outdoors and is brought indoors. It spreads indoors and makes hay fever symptoms worse.
As countermeasures against hay fever, it is sufficient to use a mask and glasses that do not allow pollen to pass, or to wear a wide-brimmed hat, but wearing these is cumbersome, reducing the amount of pollen adhering to clothes and preventing it from being diffused indoors. However, it is important as a countermeasure against hay fever. However, there is no literature regarding a processing method for preventing pollen from adhering to clothes. Therefore, a conventional technique which is not pollen but does not allow dust such as dust and dust to adhere to the cloth is shown below.
[0004]
As a technique for preventing dust such as dust and dust from adhering to the fabric, there is an antifouling process (water repellent, oil repellent and antistatic process). However, although water / oil repellent processing is effective against water-based stains, dry stains tend to adsorb dust.
Antistatic processing has an effect of preventing the adsorption of dust to synthetic fibers, but is not very effective for natural fibers and has insufficient washing durability.
Further, there is a method of applying a physical force to the surface of the fabric to smooth the surface and prevent dust. However, this method loses smoothness due to washing and cannot provide durability.
Furthermore, as another method, there is a method of increasing the fabric density. In this method, although an effect of preventing pollen from passing through the clothes is seen, there is no effect of preventing pollen from adhering to the fabric.
[0005]
[Problems to be solved by the invention]
