Down leak-proofing fabric and processing method thereof

Abstract

The invention provides a down leak-proofing fabric and a processing method thereof. WS type hot melt adhesives are sprayed on a textile fabric to be laminated with a film-covering material, and hot-pressing treatment is performed to obtain the down leak-proofing fabric. Compared with the prior art, according to the down leak-proofing fabric, a film-covering functional fabric is prepared through ahot melt adhesive laminating process. A natural fiber fabric with good air permeability and good skin-friendly property is selected as the textile fabric, organization structures are not limited, a jacquard fabric can even be selected, and a thin film with high permeability is selected as the film-covering material. The surface of the thin film is in contact with down filling materials, and the human body is in contact with natural fiber fabric components. No chemicals are added to the contact surface of a natural fiber fabric in contact with the human body, which will not lead to phenomena such as sensitization and the like of susceptible population. Moreover, down products processed have high down leak-proofing performance, almost zero down leak of the down products is achieved, and thedown products have broad application prospects. The down leak-proofing fabric has good down leak-proofing performance and fastness and can be washed repeatedly, and the down leak-proofing performanceand wearing comfort performance are not reduced after washing 10 times.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to an anti-drilling fleece fabric and a processing method thereof. Background technique [0002] Down products are favored by consumers in cold regions at home and abroad for their special advantages such as lightness, softness, softness and warmth retention, and the demand in the international market is strong. The down products industry is a labor-intensive industry, and the advantages of my country's export enterprises are relatively significant. Under the situation that the export of down products in my country is growing steadily year by year, the quality requirements of down products in many countries and regions in the world have become increasingly strict in recent years. exit. Among them, the down drilling phenomenon of down products has always been one of the hot topics of consumer complaints. If the down feather drills out of the down product during use, it will not ...

If the down and feathers are drilled out of the down product during use, it will not only affect the appearance but also affect its warmth retention

[0003] In the prior art, there are usually the following two methods to obtain down products with excellent anti-drilling performance: one is to use high-count and high-density chemical fiber fabrics as lining fabrics, and then choose suitable quilt fabrics, which means that the down filling materials There are two layers of fabric barriers, and the breathability and wearing comfort of down products processed by this method are poor; the second is to carry out the anti-drilling finishing method on the quilt fabric, specifically coating finishing, calendering and baking treatment , such processing will lead to a significant decrease in the feel and softness of the fabric, and the tear resistance will deteriorate

At the same time, the coating is a chemical additive. During the course of taking, the chemical agent may fall off, resulting in a decrease in the anti-drilling performance. In severe cases, some sensitive people will have allergies and other symptoms. The composition of the coating finishing agent is also prone to light yellowing The phenomenon that affects the appearance of the product
