Detailed Description

A fabric containing PE (polyethylene) staple fibers and thermally adhered with resin comprises a fabric body, wherein the yarns of the fabric body are polyethylene staple fiber yarns, air gaps exist among the staple fibers of the polyethylene staple fiber yarns, and the air gaps form a heat insulation layer which can reduce the occurrence of thermal damage to the yarns due to direct contact with hot air. The surface of the polyethylene short fiber fabric body is adhered with resin at high temperature.

The polyethylene staple fiber yarn is one of a core spun yarn, a cladding spun yarn, a double-twisted spun yarn or a staple fiber single yarn containing polyethylene staple fibers, and the staple fiber yarn prepared by any one process can be used.

According to the requirements of the use environment of the product, the resin can be adhered to the surface of the fabric body in a bead, rubber block or whole rubber layer. The bead fabric can play a role of skid resistance, such as a glove with beads on the palm. The fabric of the patch may increase friction, such as a palm-sized glove. The glove with the whole adhesive layer is hot-pasted, so that the whole glove can be protected, and the adhesive force between the short fibers and the adhesive layer is higher.

In the above resin, the resin material may be one of PVC resin, PE polyethylene, PP polypropylene, PS polystyrene, PA polyamide, POM polyformaldehyde, PC polycarbonate, polyphenylene oxide, polysulfone, and rubber.

The following provides a weaving process of a fabric containing PE staple fibers and thermally attached with resin, which comprises the following steps:

s1, obtaining the polyethylene staple fiber yarn through core-spun, cladding, double-twist or spun yarn processes. The length of the polyethylene is controlled to be 25-75 cm, and the thickness of the polyethylene is controlled to be 20-100D.

And S2, weaving the polyethylene spun yarn into a fabric. The fabric may be a glove, cuff, or fabric.

In order to improve the softness and the resistance of the fabric at high temperature, the above process is added with the following steps before step S3: the fabric is cooled by a cooling device in advance, the cooling temperature is controlled to be 0-10 ℃, and the cooling time is controlled to be 3-5 s. The temperature is not low enough, the cooling effect is poor, and if the temperature is too low, the fabric is easy to become brittle. The softness of the fabric cooled in the temperature range is found to be softer than the hand feeling of the fabric subjected to the hot pressing treatment at normal temperature, and the fabric also has high temperature resistance.

And S3, hot-pressing the resin on the surface of the fabric at 150 ℃, wherein the resin is in the form of point beads, rubber blocks or rubber layers on the surface of the fabric body. When hot pressing, a high-temperature resistant breathable layer pad with a smooth and flat surface is padded below the fabric. The high-temperature-resistant breathable layer cushion is made of one canvas breathable layer and is formed by weaving special high-temperature-resistant cotton threads, the high-density processing technology adopted by the cotton threads can effectively prevent the cotton threads from being stretched like other cotton bags, but has breathability and air accommodating gaps. The high-temperature-resistant breathable layer can resist high temperature, and the high temperature resistance can reach 200 degrees. The original fabric is directly placed on a metal mold for hot pressing, and the heat of a part of the metal mold is fed back to the fabric, so that the fabric is subjected to double-sided high-temperature heat, and the tolerance of the fabric is poor. After the high-temperature-resistant breathable layer cushion is used in a hot pressing process, a part of heat can be led out of the high-temperature-resistant breathable layer cushion or a certain heat isolating layer is formed by an air gap of the high-temperature-resistant breathable layer cushion, so that the high-temperature heat on the other surface of the fabric is reduced, and the high-temperature resistance of the fabric is further improved. In conclusion, the hot-pressed polyethylene staple fiber fabric with the dotted beads, the rubber blocks or the whole rubber layer has the advantages of convenient processing and low processing cost in the whole process, and the product also has the advantages of softness, good tolerance, good anti-skid performance and the like.
