COMPOSITE YARN

Abstract

Provided is a composite yarn. The composite yarn includes a core and a sheath. The core is made of a thermoplastic material; wherein the thermoplastic material is selected from a group consisting of: a polyester, a polyamide, a polyacrylonitrile and any combination thereof. The sheath formed around the core is made of a cladding material, and the cladding material comprises polyvinyl butyral; wherein the polyvinyl butyral has a melt flow rate ranging from 2 g/10 min to 35 g/10 min; the melt flow rate is measured by a standard method ASTM D1238 at 190° C. with 2.16 kg load.

12. The composite yarn as claimed in claim 7, wherein the polyvinyl butyral has the melt flow rate ranging from 7 grams per 10 minutes to 15 grams per 10 minutes; the melt flow rate is measured by the standard method ASTM D1238 at 190° C. with 2.16 kilograms load.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The sole FIGURE is a structural schematic view showing that a composite yarn of one preferable example in accordance with the instant disclosure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, one skilled in the arts can easily realize the advantages and effects of the instant disclosure from the following example. Therefore, it should be understood that the descriptions proposed herein are just preferable examples for the purpose of illustrations only, not intended to limit the scope of the disclosure. Various modifications and variations could be made in order to practice or apply the instant disclosure without departing from the spirit and scope of the disclosure.

[0021] The preferred embodiment of the instant disclosure will hereinafter be described in conjunction with the appended drawing, provided to illustrate the technical means adopted to achieve the objective of the instant disclosure.

[0022] With reference to the sole FIGURE, a composite yarn 1 of Example 1 of the instant disclosure comprised a core 10 and a sheath 20.

[0023] The core 10 was a single yarn made by twisting multiple polyamide filaments.

[0024] The sheath 20 was wrapped around the core 10. The sheath 20 was composed of a cladding material, which comprised PVB and a plasticizer. Provided that the PVB was in an amount of 100 parts by weight, the plasticizer was in an amount of 20 parts by weight.

[0025] The PVB had a melt flow rate of 12 g/10 min according to a standard method ASTM D1238 at 190° C. with 2.16 kg load.

[0026] The PVB was obtained by recycling wasted laminated safety glass.

[0027] The sheath 20 had a thickness of 0.25 mm.

[0028] In conclusion, the sheath of the composite yarn of the instant disclosure is fully wrapped around the core and the sheath is composed of the cladding material comprising PVB, so the sheath can make an obtained fabric set directly through a hot-melt process when the composite yarn is used in subsequent manufacture of fabrics. Therefore, the textile manufacturing will be simplified. In addition, the cladding material is essentially composed of PVB, which can sufficiently meet the requirements of environmental protection, so the composite yarn indeed can achieve the objective of the instant disclosure.

[0029] Even though numerous characteristics and advantages of the instant disclosure have been set forth in the foregoing description, together with details of the structure and features of the disclosure, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
