Background

The filling non-woven fabric is a common variety of non-woven fabrics and is widely applied to the field of warm keeping and cold proofing. The human body exchanges heat with the environment through clothing, mattresses, sleeping bags, etc., thereby achieving the thermal comfort of the human body. The most basic condition for thermal comfort is to maintain the thermal balance of the human body, i.e. the relative balance between the heat generated by the human body itself and the heat dissipated to the environment. The function of the warm-keeping material is to strengthen or weaken the heat dissipation path, so that the energy exchange reaches relative balance, and the human body is warm and comfortable.

The conventional technology of the spray-bonded cotton is that the fiber raw material is carded into a single-layer thin net, then the single-layer thin net is laid into a flocculus, adhesive is sprayed on two sides of the flocculus, certain pressure is applied during spraying, vacuum suction is applied to the other side of the flocculus, the adhesive is permeated into the interior of the fibre net, and then the fibre net is dried and solidified, so that the connection points between the fibers are bonded together, and the spray-bonded cotton can be used as the thermal-insulation filler of clothes, trousers, mattresses and the like.

However, when the existing spray-bonded cotton is used as a warm-keeping filler, if the warm-keeping performance of the existing spray-bonded cotton is improved, the thickness of the spray-bonded cotton needs to be increased, so that clothes are overstaffed, and how to reduce the thickness of the spray-bonded cotton for warm-keeping filling on the premise of ensuring the warm-keeping performance becomes a problem to be solved.

In the first collodion-spraying layer 2 and the second collodion-spraying layer 4, high-crimp hollow polyester staple fibers are sprayed after being formed into a net, and then chemical adhesive is sprayed for crosslinking and drying to obtain the product. The chemical adhesive used is an environmentally friendly chemical adhesive. The high-crimp hollow short fibers have high crimpability, the fineness is 2D, the length is 38mm, the crimpability of the high-crimp hollow short fibers used in the embodiment is 10-20 pieces/inch, the hollowness of the high-crimp hollow polyester short fibers used is 16-18%, and the hollow fibers have good heat retention property.
