On the weaving machine, the warp yarns are subjected to three frictions: stretch, strain and abrasion. So, the sizing of the warp yarn is essential to reduce breakage of the yarn and thus ensure production does not stop on the weaving machine.
As SMS knows that the value of a warp sizing material is related to its effectiveness in protecting yarns from breakage due to the forces of weaving, we are proud to present SIZETEX® Series, a solution created for ideal sizing, especially for cotton yarn.
SIZETEX® PVS300D is our high-end modified starch product for sizing, especially for cotton-spun yarn. It can be used for partial replacement (40-60%) of the PVA for textile sizing. It has much better penetrability and is more environmentally friendly than PVA.
SIZETEX® A55, SIZETEX® 5, SMS GSA are used in the adjustment of the appropriate viscosity of size with levels of penetration, while SIZETEX® A55 maintains a stable viscosity with the deviation of temperature.
SIZETEX® KLIC540D is a starch copolymer with an anionic character used as a sizing agent. It is used as a sizing material to function as a binder to improve the adhesion of primary base sizing (film former) and the yarn. There is no need to be cooked, but it can be heated up for dispersing a lubricant-like wax or adding other components, such as starch and PVA, which may be blended. A major advantage is the high binding strength of the yarn under weaving, which allows for a reduction in the hairiness of the sized yarn.
